  Previous information concerning my issue can be found here: Virus...? Tons of people talking. Not sure where else to ask. I heard the loud sounds and whatnot from one of the ads but nothing was harmed and other than having the life scared out of me nothing was immediately affected. Literally nothing has changed. I really don't know what to do. My PC seems fine and from what Malwarebytes and Spybot tells me none of my files have been infected with anything. If you need more information I will be glad to supply it. Thanks in advance. Malwarebytes quick and full scan: Clean. Spybot S&D scan: Clean.

• OSGI Declarative Services (DS): What is a good way of using service component instances

  - by Christoph

  I am just getting started with OSGI and Declarative Services (DS) using Equinox and Eclipse PDE. I have 2 Bundles, A and B. Bundle A exposes a component which is consumed by Bundle B. Both bundles also expose this service to the OSGI Service registry again. Everything works fine so far and Equinox is wireing the components together, which means the Bundle A and Bundle B are instanciated by Equinox (by calling the default constructor) and then the wireing happens using the bind / unbind methods. Now, as Equinox is creating the instances of those components / services I would like to know what is the best way of getting this instance? So assume there is third class class which is NOT instantiated by OSGI: Class WantsToUseComponentB{ public void doSomethingWithComponentB(){ // how do I get componentB??? Something like this maybe? ComponentB component = (ComponentB)someComponentRegistry.getComponent(ComponentB.class.getName()); } I see the following options right now: 1. Use a ServiceTracker in the Activator to get the Service of ComponentBundleA.class.getName() (I have tried that already and it works, but it seems to much overhead to me) and make it available via a static factory methods public class Activator{ private static ServiceTracker componentBServiceTracker; public void start(BundleContext context){ componentBServiceTracker = new ServiceTracker(context, ComponentB.class.getName(),null); } public static ComponentB getComponentB(){ return (ComponentB)componentBServiceTracker.getService(); }; } 2. Create some kind of Registry where each component registers as soon as the activate() method is called. public ComponentB{ public void bind(ComponentA componentA){ someRegistry.registerComponent(this); } or public ComponentB{ public void activate(ComponentContext context){ someRegistry.registerComponent(this); } } } 3. Use an existing registry inside osgi / equinox which has those instances? I mean OSGI is already creating instances and wires them together, so it has the objects already somewhere. But where? How can I get them? Conclusion Where does the class WantsToUseComponentB (which is NOT a Component and NOT instantiated by OSGI) get an instance of ComponentB from? Are there any patterns or best practises? As I said I managed to use a ServiceTracker in the Activator, but I thought that would be possible without it. What I am looking for is actually something like the BeanContainer of Springframework, where I can just say something like Container.getBean(ComponentA.BEAN_NAME). But I don't want to use Spring DS. I hope that was clear enough. Otherwise I can also post some source code to explain in more detail. Thanks Christoph UPDATED: Answer to Neil's comment: Thanks for clarifying this question against the original version, but I think you still need to state why the third class cannot be created via something like DS. Hmm don't know. Maybe there is a way but I would need to refactor my whole framework to be based on DS, so that there are no "new MyThirdClass(arg1, arg2)" statements anymore. Don't really know how to do that, but I read something about ComponentFactories in DS. So instead of doing a MyThirdClass object = new MyThirdClass(arg1, arg2); I might do a ComponentFactory myThirdClassFactory = myThirdClassServiceTracker.getService(); // returns a if (myThirdClassFactory != null){ MyThirdClass object = objectFactory.newInstance(); object.setArg1("arg1"); object.setArg2("arg2"); } else{ // here I can assume that some service of ComponentA or B went away so MyThirdClass Componenent cannot be created as there are missing dependencies? } At the time of writing I don't know exactly how to use the ComponentFactories but this is supposed to be some kind of pseudo code :) Thanks Christoph

• Adobe Coldfusion Railo OpenBD Apache Tomcat Multiple Sites

  - by chris hough

  Here's what I am trying to do, unless I am crazy: I am trying to use Tomcat with the multiple workers, so far I got OpenBD working, but having trouble with Railo, and will be tackling Adobe after. each engine deployed as a war separated by different workers I wanted to keep both the sites and engines inside my sites directory I have to remap the symlink for the WEB-INF when I switch engines = have not found a way around this my thought is to have everything separated into modules and I want to be able to execute both cfm and php code in a single site.  Ideally, it would be amazing if there would be a way to not have to remap the symlink as well. thoughts? can this be done? I am trying to mimic how this would be setup on a live server, not using eclipse for example. here is what I am working with so far: my apache workers.properties worker.list=openbd, openbdadmin, railo, railoadmin  worker.openbd.type=ajp13  worker.openbd.host=local.mydev.openbd  worker.openbd.port=8009 worker.openbdadmin.type=ajp13  worker.openbdadmin.host=local.admin.openbd worker.openbdadmin.port=8009   worker.railo.type=ajp13  worker.railo.host=local.mydev.railo  worker.railo.port=8009 worker.railoadmin.type=ajp13  worker.railoadmin.host=local.admin.railo worker.railoadmin.port=8009   my tomcat servers.xml < Host name="local.admin.openbd" appBase="/Users/[myusername]/Websites/coldfusion.engines"  unpackWARs="false" autoDeploy="true" xmlValidation="true" xmlNamespaceAware="false"        < Context path="" docBase="openbd/" reloadable="true" privileged="true" antiResourceLocking="false" anitJARLocking="false" allowLinking="true" < /Host        < Host name="local.admin.railo"   appBase="/Users/[my username]/Websites/coldfusion.engines" unpackWARs="false" autoDeploy="true" xmlValidation="true" xmlNamespaceAware="false"        < Context path="" docBase="railo/"  reloadable="true" privileged="true" antiResourceLocking="false" anitJARLocking="false" allowLinking="true" < /Host < Host name="local.mydev.openbd"   appBase="/Users/[my username]/Websites/coldfusion.engines" unpackWARs="false" autoDeploy="true" xmlValidation="true" xmlNamespaceAware="false" < Context path="" docBase="/Users/[my username]/Websites/example.mydev/wwwroot/"  reloadable="true" privileged="true" antiResourceLocking="false" anitJARLocking="false" allowLinking="true"< /Context < /Host < Host name="local.mydev.railo"   appBase="/Users/[my username]/Websites/coldfusion.engines"  unpackWARs="false" autoDeploy="true" xmlValidation="true" xmlNamespaceAware="false" < Context path="" docBase="/Users/[my username]/Websites/example.mydev/wwwroot/"  reloadable="true" privileged="true" antiResourceLocking="false" anitJARLocking="false" allowLinking="true" < /Host my apache vhosts ServerName local.admin.openbd DocumentRoot /Users/[my username]/Websites/coldfusion.engines/openBD/ #Mount OpenBD and tell it to only server cfml files JkMount /*.cfm openbdadmin ErrorLog "/Users/[my username]/Websites/apache.logs/local_openbdadmin_error.log" ServerName local.admin.railo DocumentRoot /Users/[my username]/Websites/coldfusion.engines/railo/ #Mount Railo and tell it to only server cfml files JkMount /*.cfm railoadmin ErrorLog "/Users/[my username]/Websites/apache.logs/local_railoadmin_error.log" ServerName local.mydev DocumentRoot /Users/[my username]/Websites/example.mydev/wwwroot ErrorLog "/Users/[my username]/Websites/apache.logs/local_example_mydev_error.log" ServerName local.mydev.openbd DocumentRoot /Users/[my username]/Websites/example.mydev/wwwroot #Mount OpenBD and tell it to only server cfml files JkMount /*.cfm openbd ErrorLog "/Users/[my username]/Websites/apache.logs/local_example_mydev_openbd_error.log" ServerName local.mydev.railo DocumentRoot /Users/[my username]/Websites/example.mydev/wwwroot JkMount /*.cfm railo ErrorLog "/Users/[my username]/Websites/apache.logs/local_example_mydev_railo_error.log" my folder structure I am using websites/apache.logs/ websites/coldfusion.engines/ websites/coldfusion.engines/cfusion/ websites/coldfusion.engines/openBD/ websites/coldfusion.engines/railo/ websites/example.mydev/ websites/example.mydev/wwwroot/ websites/example.mydev/wwwroot/index.cfm   websites/example.mydev/wwwroot/index.htm   websites/example.mydev/wwwroot/index.php   error log output [Thu Aug 27 00:54:50.443 2009] [11279:2686719776] [info] init_jk::mod_jk.c (3183): mod_jk/1.2.28 initialized [Thu Aug 27 00:54:51.346 2009] [11280:2686719776] [info] init_jk::mod_jk.c (3183): mod_jk/1.2.28 initialized [Thu Aug 27 00:55:18.963 2009] [11284:2686719776] [info] jk_open_socket::jk_connect.c (594): connect to 127.0.0.1:8009 failed (errno=61) [Thu Aug 27 00:55:18.963 2009] [11284:2686719776] [info] ajp_connect_to_endpoint::jk_ajp_common.c (922): Failed opening socket to (127.0.0.1:8009) (errno=61) [Thu Aug 27 00:55:18.963 2009] [11284:2686719776] [error] ajp_send_request::jk_ajp_common.c (1507): (openbdadmin) connecting to backend failed.

• jquery-autocomplete does not work with my django app.

  - by HWM-Rocker

  Hi everybody, I have a problem with the jquery-autocomplete pluging and my django script. I want an easy to use autocomplete plugin. And for what I see this (http://code.google.com/p/jquery-autocomplete/) one seems very usefull and easy. For the django part I use this (http://code.google.com/p/django-ajax-selects/) I modified it a little, because the out put looked a little bit weired to me. It had 2 '\n' for each new line, and there was no Content-Length Header in the response. First I thought this could be the problem, because all the online examples I found had them. But that was not the problem. I have a very small test.html with the following body: <body> <form action="" method="post"> <p><label for="id_tag_list">Tag list:</label> <input id="id_tag_list" name="tag_list" maxlength="200" type="text" /> </p> <input type="submit" value="Submit" /> </form> </body> And this is the JQuery call to add autocomplete to the input. function formatItem_tag_list(bla,row) { return row[2] } function formatResult_tag_list(bla,row) { return row[1] } $(document).ready(function(){ $("input[id='id_tag_list']").autocomplete({ url:'http://gladis.org/ajax/tag', formatItem: formatItem_tag_list, formatResult: formatResult_tag_list, dataType:'text' }); }); When I'm typing something inside the Textfield Firefox (firebug) and Chromium-browser indicates that ther is an ajax call but with no response. If I just copy the line into my browser, I can see the the response. (this issue is solved, it was a safety feature from ajax not to get data from another domain) For example when I am typing Bi in the textfield, the url "http://gladis.org/ajax/tag?q=Bi&max... is generated. When you enter this in your browser you get this response: 4|Bier|Bier 43|Kolumbien|Kolumbien 33|Namibia|Namibia Now my ajax call get the correct response, but there is still no list showing up with all the possible entries. I tried also to format the output, but this doesn't work either. I set brakepoints to the function and realized that they won't be called at all. Here is a link to my minimum HTML file http://gladis.org/media/input.html Has anybody an idea what i did wrong. I also uploaded all the files as a small zip at http://gladis.org/media/example.zip. Thank you for your help! [Edit] here is the urls conf: (r'^ajax/(?P<channel>[a-z]+)$', 'ajax_select.views.ajax_lookup'), and the ajax lookup channel configuration AJAX_LOOKUP_CHANNELS = { # the simplest case, pass a DICT with the model and field to search against : 'tag' : dict(model='htags.Tag', search_field='text'), } and the view: def ajax_lookup(request,channel): """ this view supplies results for both foreign keys and many to many fields """ # it should come in as GET unless global $.ajaxSetup({type:"POST"}) has been set # in which case we'll support POST if request.method == "GET": # we could also insist on an ajax request if 'q' not in request.GET: return HttpResponse('') query = request.GET['q'] else: if 'q' not in request.POST: return HttpResponse('') # suspicious query = request.POST['q'] lookup_channel = get_lookup(channel) if query: instances = lookup_channel.get_query(query,request) else: instances = [] results = [] for item in instances: results.append(u"%s|%s|%s" % (item.pk,lookup_channel.format_item(item),lookup_channel.format_result(item))) ret_string = "\n".join(results) resp = HttpResponse(ret_string,mimetype="text/html") resp['Content-Length'] = len(ret_string) return resp

• Can't connect to smtp (postfix, dovecot) after making a change and trying to change it back

  - by UberBrainChild

  I am using postfix and dovecot along with zpanel and I tried enabling SSL and then turned it off as I did not have SSL configured yet and I realized it was a bit stupid at the time. I am using CentOS 6.4. I get the following error in the mail log. (I changed my host name to "myhostname" and my domain to "mydomain.com") Oct 20 01:49:06 myhostname postfix/smtpd[4714]: connect from mydomain.com[127.0.0.1] Oct 20 01:49:16 myhostname postfix/smtpd[4714]: fatal: no SASL authentication mechanisms Oct 20 01:49:17 myhostname postfix/master[4708]: warning: process /usr/libexec/postfix/smtpd pid 4714 exit status 1 Oct 20 01:49:17 amyhostname postfix/master[4708]: warning: /usr/libexec/postfix/smtpd: bad command startup -- throttling Reading on forums and similar questions I figured it was just a service that was not running or installed.

• Groovy/Grails Using WSClient to consume .net web service

  - by ROb

  I'm pretty new to both Grails/Groovy/Web services and i'm consuming a .net web service .. I have some code connects to the service using grails WS-client plugin : WebService webService def result = { def wsdl = ApplicationHolder.application.parentContext.getResource('WEB-INF/productsSoap.wsdl') def proxy = webService.getClient(wsdl.getURL().toString()) def productTypeListResponse = proxy.ProductTypeList() } I also used soapUI to examine the data returned from the web service which gave .. <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <soap:Body> <ProductTypeListResponse xmlns="http://tempuri.org/"> <ProductTypeListResult> <xs:schema id="ProductTypeListResult" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata"> <xs:element name="ProductTypeListResult" msdata:IsDataSet="true" msdata:UseCurrentLocale="true"> <xs:complexType> <xs:choice minOccurs="0" maxOccurs="unbounded"> <xs:element name="ProductTypeListResult"> <xs:complexType> <xs:sequence> <xs:element name="PRD_TypeId" type="xs:int" minOccurs="0"/> <xs:element name="PRD_TypeName" type="xs:string" minOccurs="0"/> <xs:element name="PRD_Type" type="xs:string" minOccurs="0"/> </xs:sequence> </xs:complexType> </xs:element> </xs:choice> </xs:complexType> </xs:element> </xs:schema> <diffgr:diffgram xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1"> <ProductTypeListResult xmlns=""> <ProductTypeListResult diffgr:id="ProductTypeListResult1" msdata:rowOrder="0"> <PRD_TypeId>2</PRD_TypeId> <PRD_TypeName>ProdType2</PRD_TypeName> <PRD_Type>S</PRD_Type> </ProductTypeListResult> <ProductTypeListResult diffgr:id="ProductTypeListResult2" msdata:rowOrder="1"> <PRD_TypeId>3</PRD_TypeId> <PRD_TypeName>ProdType3</PRD_TypeName> <PRD_Type>C</PRD_Type> </ProductTypeListResult> <ProductTypeListResult diffgr:id="ProductTypeListResult3" msdata:rowOrder="2"> <PRD_TypeId>4</PRD_TypeId> <PRD_TypeName>ProdType4</PRD_TypeName> </ProductTypeListResult> </ProductTypeListResult> </diffgr:diffgram> </ProductTypeListResult> </ProductTypeListResponse> which is a .net dataset ..

• Open source CMS for a university department

  - by Greg Kuperberg

  I realize that this type of question gets asked over and over again. Nonetheless, I want to ask a more specific version. I'm in a university math department. Long ago our sysadmins (or just one at the time) switched to a web content management system. At the time, Zope looked like an informed choice. We have used Zope for years, but at least in my opinion, it has always been a controversial decision. At the time I didn't understand why it was so important to have a web CMS. Now I see that it certainly is important, but I don't know that it should be Zope. The good (even necessary) features of Zope for us are: It's free and Linux-based. It is a true CMS and not something else (e.g. wiki or blog) It lets you write HTML and scripts. What I really don't like about Zope is that the outcome of using it is all-or-nothing in a lot of ways. At least in convenient use, it ends up dividing the enterprise into superusers who can do everything, and lusers who can't do anything (except write their own home pages in plain HTML). It has a huge user manual, which end users won't have time to read. Somehow with the access permissions, the simple thing to do is to let a few admins access all of the source and data and that's it. Since this is a math department, the user base varies from real novices to people who understand computers reasonably well. But as it stands, any change that involves Zope has to go through the sysadmins. When the sysadmins are in a hurry, sometimes they will also just add plain HTML pages to the web site instead of using the Zope framework. It doesn't help matters that Zope is fairly disk-intensive and fairly hype-intensive. Not to dwell on Zope too much, but I am wondering what is the right web CMS for a mixed user base of terminal novices, quick studies, and experienced users. Some users might want intermediate permissions, e.g. read permission but not write permission, or permission to change some subset of the pages or see some subset of the database tables. Also it should be Linux-based and open source and a little bit scalable, and of course widely used and well-supported is a good idea. I might guess that the answer is Drupal just because that was the general answer before, but I don't know if it is the right type of CMS for this purpose. (But note that Python is a relatively popular language in a math department, among other reasons because Sage is based on Python.) I can see that I didn't completely define the question and that people are guessing what type of site it is. It is the UC Davis Math Department. The main structure of the site is not suitable for a wiki and it is also not the same thing as a course environment like Moodle. Rather, the site is mostly structured as a generic medium-small enterprise. Some components of the site could be a wiki, Moodle, LaTeX plugin, Request Tracker, etc. However, the main issue is not these components. The main issue is that it would be better to decentralize management of the site. Right now, everything that is in the Zope CMS has to go through the sysadmins. Every other user in the department either has to put in a request to them, or write their own web pages with no help from Zope. There are two main reasons for this: (1) Other people in the department don't have time to read the Zope manual. (2) It's a hassle to set up intermediate permissions in Zope. However, there are other people in the department who know how to write computer programs and use markup languages. I wouldn't want a solution that assumes that users either can't be trusted with much more than drag-and-drop, or that they are IT professionals who sleep with documentation manuals. I'm wondering if Plone/Zope still has this quality, since certainly Zope by itself does. But I also wonder sometimes if common-sense flexibility is unfashionable these days, and that things in general have be either mindlessly easy or incredibly powerful.

• Using AsyncTask to display data in ListView, but onPostExecute not being called

• Soft keyboard "del" key fails in EditText on Gallery widget

  - by droidful

  Hi, I am developing an application in Eclipse build ID 20090920-1017 using android SDK 2.2 and testing on a Google Nexus One. For the purposes of the tests below I am using the IME "Android keyboard" on a non-rooted phone. I have an EditText widget which exhibits some very strange behavior. I can type text, and then press the "del" key to delete that text; but after I enter a 'space' character, the "del" key will no longer remove characters before that space character. An example speaks a thousand words, so consider the following two incredibly simple applications... Example 1: An EditText in a LinearLayout widget: package com.example.linear.edit; import android.app.Activity; import android.os.Bundle; import android.view.ViewGroup.LayoutParams; import android.widget.EditText; import android.widget.Gallery; import android.widget.LinearLayout; public class LinearEdit extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); LinearLayout layout = new LinearLayout(getApplicationContext()); layout.setLayoutParams(new Gallery.LayoutParams(Gallery.LayoutParams.MATCH_PARENT, Gallery.LayoutParams.MATCH_PARENT)); EditText edit = new EditText(getApplicationContext()); layout.addView(edit, new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT)); setContentView(layout); } } Run the above application, enter text "edit example", then press the "del" key several times until the entire sentence is deleted. Everything Works fine. Now consider example 2: An EditText in a Gallery widget: package com.example.gallery.edit; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.ViewGroup; import android.view.ViewGroup.LayoutParams; import android.widget.ArrayAdapter; import android.widget.EditText; import android.widget.Gallery; import android.widget.LinearLayout; public class GalleryEdit extends Activity { private final String[] galleryData = {"string1", "string2", "string3"}; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Gallery gallery = new Gallery(getApplicationContext()); gallery.setAdapter(new ArrayAdapter(getApplicationContext(), android.R.layout.simple_list_item_1, galleryData) { @Override public View getView(int position, View convertView, ViewGroup parent) { LinearLayout layout = new LinearLayout(getApplicationContext()); layout.setLayoutParams(new Gallery.LayoutParams(Gallery.LayoutParams.MATCH_PARENT, Gallery.LayoutParams.MATCH_PARENT)); EditText edit = new EditText(getApplicationContext()); layout.addView(edit, new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT)); return layout; } }); setContentView(gallery); } } Run the above application, enter text "edit example", then press the "del" key several times. If you are getting the same problem as me then you will find that you can't deleted past the 'space' character. All is not well. If anyone could shed some light on this issue I would be most appreciative. Regards

This is done through the Jquery Animation, not through CSS (I do this so it can fade, instead of being a straight change). Everything looks nice when the page loads, and the fades look perfect. Infact if you drag your mouse all over the place, if gives you a "trail" almost like a snake. Anyway, My next problem is that you will see there is a box in the top left, which is going to tell you information about the tile you are hovering over. This seems to work fine. When you mouse over that information box, it switches it's position (So that you can reach the tiles that were previously hidden underneath it). From my understanding, this is all working fine, and to the letter. However, After one move of the info box (One hover). Viewing the page in Firefox turns slugish. As in, after a successful move of the info box, the fade effects become very stuttered, and it doesn't pick up events as fast meaning you can't draw a "trail" on the screen. Chrome doesn't have this issue. It seems to work fine no matter what. Safari also seems ok. Although I do notice if I move my mouse really fast, it does jump a bit but not as much as firefox. Internet explorer doesn't work at all. Seems to crash the browser... And there is an error with the rounded corner plugin im using (Not sure why...). All in all, I think whatever I'm doing inside my code must be heavily sluggish. But I don't know where it is happening. Here is the full code, but I would advise go to the link to view everything. <script type="text/javascript"> $(document).ready(function() { var WindowWidth = $(window).width(); var WindowMod = WindowWidth % 20; var WindowWidth = WindowWidth - WindowMod; var BoxDimension = WindowWidth / 20; var BoxDimensionFixed = BoxDimension - 12; var dimensions = BoxDimensionFixed + 'px'; $('.gamebutton').each(function(i) { $(this).css('width', dimensions); $(this).css('height', dimensions); }); var OuterDivHeight = BoxDimension * 10; var TopMargin = ($(window).height() - OuterDivHeight) / 2; var OuterDivWidth = BoxDimension * 20; var LeftMargin = ($(window).width() - OuterDivWidth) / 2; $('#gamePort').css('margin-top', TopMargin).css('margin-left', LeftMargin).css('margin-right', LeftMargin); $('.gamebutton img').each(function(i) { $(this).hover( function () { $(this).animate({'opacity': 0.65}); }, function () { $(this).animate({'opacity': 1}); } ); }); $('.rounded').corners(); $('.gamebutton').each(function(i) { $(this).hover(function() { $('.gameTitlePopup').html($(this).attr('title')); FadeActive(); }); }); function FadeActive() { $('.activeInfo').fadeIn('slow'); } $('#gameInfoLeft').hover(function() { $(this).removeClass('activeInfo'); $(this).fadeOut('slow', function() { $('#gameInfoRight').addClass('activeInfo'); FadeActive(); }); }); $('#gameInfoRight').hover(function() { $(this).removeClass('activeInfo'); $(this).fadeOut('slow', function() { $('#gameInfoLeft').addClass('activeInfo'); FadeActive(); }); }); }); </script> Thanks for any help :).

• Looking for a better design: A readonly in-memory cache mechanism

  - by Dylan Lin

  Hi all, I have a Category entity (class), which has zero or one parent Category and many child Categories -- it's a tree structure. The Category data is stored in a RDBMS, so for better performance, I want to load all categories and cache them in memory while launching the applicaiton. Our system can have plugins, and we allow the plugin authors to access the Category Tree, but they should not modify the cached items and the tree(I think a non-readonly design might cause some subtle bugs in this senario), only the system knows when and how to refresh the tree. Here are some demo codes: public interface ITreeNode<T> where T : ITreeNode<T> { // No setter T Parent { get; } IEnumerable<T> ChildNodes { get; } } // This class is generated by O/R Mapping tool (e.g. Entity Framework) public class Category : EntityObject { public string Name { get; set; } } // Because Category is not stateless, so I create a cleaner view class for Category. // And this class is the Node Type of the Category Tree public class CategoryView : ITreeNode<CategoryView> { public string Name { get; private set; } #region ITreeNode Memebers public CategoryView Parent { get; private set; } private List<CategoryView> _childNodes; public IEnumerable<CategoryView> ChildNodes { return _childNodes; } #endregion public static CategoryView CreateFrom(Category category) { // here I can set the CategoryView.Name property } } So far so good. However, I want to make ITreeNode interface reuseable, and for some other types, the tree should not be readonly. We are not able to do this with the above readonly ITreeNode, so I want the ITreeNode to be like this: public interface ITreeNode<T> { // has setter T Parent { get; set; } // use ICollection<T> instead of IEnumerable<T> ICollection<T> ChildNodes { get; } } But if we make the ITreeNode writable, then we cannot make the Category Tree readonly, it's not good. So I think if we can do like this: public interface ITreeNode<T> { T Parent { get; } IEnumerable<T> ChildNodes { get; } } public interface IWritableTreeNode<T> : ITreeNode<T> { new T Parent { get; set; } new ICollection<T> ChildNodes { get; } } Is this good or bad? Are there some better designs? Thanks a lot! :)

• wave.getState() returns null

  - by RMorrisey

  When trying to call wave.getState() in my Google Wave gadget, I get back null (no state object). How can I initialize the Wave state object? I am working in the Wave Sandbox. My ModulePrefs contains the following: <Require feature="wave" /> <Require feature="rpc"/> I got the "rpc" feature from some google groups post when searching for a fix, but it doesn't seem to be any help. The gadget contains a jQuery plugin, which defines the classes I use (not shown), attaches an event handler to the link that shows up in edit mode, and sets up the callback methods with the google wave gadget initializer: $.fn.extend({ $.gork.InitPass.newButtonClick = function newButtonClick() { var jer = new $.gork.InitPass.Player('Jeremias', 12, 2); var delta = {}; delta[jer.name] = jer.serialize(); wave.getState().submitDelta(delta); }; $.gork.InitPass.modeCallback = function modeCallback() { var state = wave.getState(); var mode = wave.getMode(); $.gork.InitPass.getContainer().ipCombatState(state, (mode == wave.Mode.EDIT)); }; $.gork.InitPass.stateCallback = function stateCallback() { $.gork.InitPass.getContainer().ipCombatState( wave.getState(), (wave.getMode() == wave.Mode.EDIT)); alert('state'); }; $.gork.InitPass.init = function init() { if (wave && wave.isInWaveContainer()) { var mode = wave.getMode(); $('.gork-ip-container').ipCombatState(null, (mode == wave.Mode.EDIT)); wave.setModeCallback($.gork.InitPass.modeCallback); wave.setStateCallback($.gork.InitPass.stateCallback); } }; })(jQuery); gadgets.util.registerOnLoadHandler($.gork.InitPass.init); $(function ready() { $.gork.InitPass.getContainer().find('.gork-ip-edit .addSection a.newButton').click( $.gork.InitPass.newButtonClick); }); So there are two main pieces of functionality here: When the mode changes, ipCombatState(...) is called. This changes the visual appearance of the gadget when the user puts the gadget in Edit mode (CTRL+E), by hiding the view DIV and displaying the edit DIV. The newButtonClick callback (which is attached to the link "a.newButton" in the edit container) is supposed to add Jeremias (Nate's Shadowrun character) to the gadget state, so that he'll be appear as a table row in edit mode. I have verified that the initializer method is called, and the view/edit mode switch works just fine (except the state is null). When I click on the new button link (the link at the bottom in edit mode), and trigger the newButtonClick handler, I get an error because wave.getState() also returns null. How can I initialize the wave state so that I can work with it? The purpose of my gadget will be to keep track of combat initiative order in a Shadowrun tabletop game (4th Ed). You can test it out in Wave and see what I have so far: http://gorkwobble.herobo.com/wave/init-pass.xml The actual javascript code is externalized to: http://gorkwobble.herobo.com/wave/init-pass.js P.S. If any Shadowrun players read this, and want to hear about it when I get the gadget working, leave a comment and I'll wave you.

• How to show form in front in C#

  - by corlettk

  Folks, Please does anyone know how to show a Form from an otherwise invisible application, and have it get the focus (i.e. appear on top of other windows)? I'm working in C# .NET 3.5. I suspect I've taken "completely the wrong approach"... I do not Application.Run(new TheForm ()) instead I (new TheForm()).ShowModal()... The Form is basically a modal dialogue, with a few check-boxes; a text-box, and OK and Cancel Buttons. The user ticks a checkbox and types in a description (or whatever) then presses OK, the form disappears and the process reads the user-input from the Form, Disposes it, and continues processing. This works, except when the form is show it doesn't get the focus, instead it appears behind the "host" application, until you click on it in the taskbar (or whatever). This is a most annoying behaviour, which I predict will cause many "support calls", and the existing VB6 version doesn't have this problem, so I'm going backwards in usability... and users won't accept that (and nor should they). So... I'm starting to think I need to rethink the whole shebang... I should show the form up front, as a "normal application" and attach the remainer of the processing to the OK-button-click event. It should work, But that will take time which I don't have (I'm already over time/budget)... so first I really need to try to make the current approach work... even by quick-and-dirty methods. So please does anyone know how to "force" a .NET 3.5 Form (by fair means or fowl) to get the focus? I'm thinking "magic" windows API calls (I know Twilight Zone: This only appears to be an issue at work, we're I'm using Visual Studio 2008 on Windows XP SP3... I've just failed to reproduce the problem with an SSCCE (see below) at home on Visual C# 2008 on Vista Ulimate... This works fine. Huh? WTF? Also, I'd swear that at work yesterday showed the form when I ran the EXE, but not when F5'ed (or Ctrl-F5'ed) straight from the IDE (which I just put up with)... At home the form shows fine either way. Totaly confusterpating! It may or may not be relevant, but Visual Studio crashed-and-burned this morning when the project was running in debug mode and editing the code "on the fly"... it got stuck what I presumed was an endless loop of error messages. The error message was something about "can't debug this project because it is not the current project, or something... So I just killed it off with process explorer. It started up again fine, and even offered to recover the "lost" file, an offer which I accepted. using System; using System.Windows.Forms; namespace ShowFormOnTop { static class Program { [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); //Application.Run(new Form1()); Form1 frm = new Form1(); frm.ShowDialog(); } } } Background: I'm porting an existing VB6 implementation to .NET... It's a "plugin" for a "client" GIS application called MapInfo. The existing client "worked invisibly" and my instructions are "to keep the new version as close as possible to the old version", which works well enough (after years of patching); it's just written in an unsupported language, so we need to port it. About me: I'm pretty much a noob to C# and .NET generally, though I've got a bottoms wiping certificate, I have been a professional programmer for 10 years; So I sort of "know some stuff". Any insights would be most welcome... and Thank you all for taking the time to read this far. Consiseness isn't (apparently) my forte. Cheers. Keith.

The problem with this is it takes a lot of time when creates session factory. here is the logs 2010-04-15 23:05:28,053 DEBUG [SessionFactoryImpl] Session factory constructed with filter configurations : {} 2010-04-15 23:05:28,053 DEBUG [SessionFactoryImpl] instantiating session factory with properties: {java.vendor=Sun Microsystems Inc., sun.java.launcher=SUN_STANDARD, catalina.base=/usr/local/InstalledPrograms/apache-tomcat-6.0.20, sun.management.compiler=HotSpot Tiered Compilers, catalina.useNaming=true, os.name=Linux, sun.boot.class.path=/usr/java/jdk1.6.0_17/jre/lib/resources.jar:/usr/java/jdk1.6.0_17/jre/lib/rt.jar:/usr/java/jdk1.6.0_17/jre/lib/sunrsasign.jar:/usr/java/jdk1.6.0_17/jre/lib/jsse.jar:/usr/java/jdk1.6.0_17/jre/lib/jce.jar:/usr/java/jdk1.6.0_17/jre/lib/charsets.jar:/usr/java/jdk1.6.0_17/jre/classes, java.util.logging.config.file=/usr/local/InstalledPrograms/apache-tomcat-6.0.20/conf/logging.properties, java.vm.specification.vendor=Sun Microsystems Inc., hibernate.generate_statistics=true, java.runtime.version=1.6.0_17-b04, hibernate.cache.provider_class=org.hibernate.cache.EhCacheProvider, user.name=root, shared.loader=, tomcat.util.buf.StringCache.byte.enabled=true, hibernate.connection.release_mode=auto, user.language=en, java.naming.factory.initial=org.apache.naming.java.javaURLContextFactory, sun.boot.library.path=/usr/java/jdk1.6.0_17/jre/lib/i386, java.version=1.6.0_17, java.util.logging.manager=org.apache.juli.ClassLoaderLogManager, user.timezone=Canada/Pacific, sun.arch.data.model=32, java.endorsed.dirs=/usr/local/InstalledPrograms/apache-tomcat-6.0.20/endorsed, sun.cpu.isalist=, sun.jnu.encoding=UTF-8, file.encoding.pkg=sun.io, package.access=sun.,org.apache.catalina.,org.apache.coyote.,org.apache.tomcat.,org.apache.jasper.,sun.beans., file.separator=/, java.specification.name=Java Platform API Specification, java.class.version=50.0, user.country=US, java.home=/usr/java/jdk1.6.0_17/jre, java.vm.info=mixed mode, os.version=2.6.18-128.el5, path.separator=:, java.vm.version=14.3-b01, hibernate.jdbc.batch_size=25, java.awt.printerjob=sun.print.PSPrinterJob, sun.io.unicode.encoding=UnicodeLittle, package.definition=sun.,java.,org.apache.catalina.,org.apache.coyote.,org.apache.tomcat.,org.apache.jasper., java.naming.factory.url.pkgs=org.apache.naming, sun.rmi.dgc.client.gcInterval=3600000, user.home=/root, java.specification.vendor=Sun Microsystems Inc., java.library.path=/usr/java/jdk1.6.0_17/jre/lib/i386/server:/usr/java/jdk1.6.0_17/jre/lib/i386:/usr/java/jdk1.6.0_17/jre/../lib/i386:/usr/java/packages/lib/i386:/lib:/usr/lib, java.vendor.url=http://java.sun.com/, java.vm.vendor=Sun Microsystems Inc., hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect, sun.rmi.dgc.server.gcInterval=3600000, common.loader=${catalina.home}/lib,${catalina.home}/lib/*.jar, java.runtime.name=Java(TM) SE Runtime Environment, java.class.path=:/usr/local/InstalledPrograms/apache-tomcat-6.0.20/bin/bootstrap.jar, hibernate.bytecode.use_reflection_optimizer=false, java.vm.specification.name=Java Virtual Machine Specification, java.vm.specification.version=1.0, catalina.home=/usr/local/InstalledPrograms/apache-tomcat-6.0.20, sun.cpu.endian=little, sun.os.patch.level=unknown, hibernate.cache.use_query_cache=true, hibernate.connection.provider_class=org.springframework.orm.hibernate3.LocalDataSourceConnectionProvider, java.io.tmpdir=/usr/local/InstalledPrograms/apache-tomcat-6.0.20/temp, java.vendor.url.bug=http://java.sun.com/cgi-bin/bugreport.cgi, server.loader=, os.arch=i386, java.awt.graphicsenv=sun.awt.X11GraphicsEnvironment, java.ext.dirs=/usr/java/jdk1.6.0_17/jre/lib/ext:/usr/java/packages/lib/ext, user.dir=/, line.separator=, java.vm.name=Java HotSpot(TM) Server VM, hibernate.cache.use_second_level_cache=true, file.encoding=UTF-8, java.specification.version=1.6, hibernate.show_sql=true} 2010-04-15 23:08:53,516 DEBUG [AbstractEntityPersister] Static SQL for entity: com.vsd.model.Order There you can see the time delay of more than 3 mins in executing these processes.

• Problem with Google Calendar API invocation at server side

  - by Raffo

  Hi guys, I have problems with the invocation of the Google Calendar API. I downloaded the library for java and I added as external JAR in eclipse the following files: gdata-core, gdata-calendar, gdata- calendar-meta, gdata-client-meta, gdata-client. Then, I created a the method as it follows: import com.google.gdata.client.calendar.CalendarService; import com.google.gdata.data.calendar.CalendarEntry; import com.google.gdata.data.calendar.CalendarFeed; import com.google.gwt.user.server.rpc.RemoteServiceServlet; public class GCalServImpl extends RemoteServiceServlet implements GCalServ { @Override public String RetrieveCalendars() { // TODO Auto-generated method stub // Create a CalenderService and authenticate try{ CalendarService myService = new CalendarService("taskR"); myService.setUserCredentials(***username***, "***password***"); // Send the request and print the response URL feedUrl = new URL("http://www.google.com/calendar/feeds/default/ allcalendars/full"); CalendarFeed resultFeed = myService.getFeed(feedUrl, CalendarFeed.class); System.out.println("Your calendars:"); System.out.println(); String s = ""; for (int i = 0; i < resultFeed.getEntries().size(); i++) { CalendarEntry entry = resultFeed.getEntries().get(i); s=entry.getTitle().getPlainText(); System.out.println("\t" + s); return s; } }catch(Exception e){ e.printStackTrace(); } return null; } I then call it from the client side doing a basic async invocation. If I try to launch the program I got the following errors: WARNING: Error for /taskr/cal java.lang.NoClassDefFoundError: com/google/gdata/client/calendar/ CalendarService at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Class.java:2389) at java.lang.Class.getConstructor0(Class.java:2699) at java.lang.Class.newInstance0(Class.java:326) at java.lang.Class.newInstance(Class.java:308) at org.mortbay.jetty.servlet.Holder.newInstance(Holder.java:153) at org.mortbay.jetty.servlet.ServletHolder.initServlet(ServletHolder.java: 428) at org.mortbay.jetty.servlet.ServletHolder.getServlet(ServletHolder.java: 339) at org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java: 487) at org.mortbay.jetty.servlet.ServletHandler $CachedChain.doFilter(ServletHandler.java:1166) at com.google.appengine.api.blobstore.dev.ServeBlobFilter.doFilter(ServeBlobFilter.java: 51) at org.mortbay.jetty.servlet.ServletHandler $CachedChain.doFilter(ServletHandler.java:1157) at com.google.apphosting.utils.servlet.TransactionCleanupFilter.doFilter(TransactionCleanupFilter.java: 43) at org.mortbay.jetty.servlet.ServletHandler $CachedChain.doFilter(ServletHandler.java:1157) at com.google.appengine.tools.development.StaticFileFilter.doFilter(StaticFileFilter.java: 122) at org.mortbay.jetty.servlet.ServletHandler $CachedChain.doFilter(ServletHandler.java:1157) at org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java: 388) at org.mortbay.jetty.security.SecurityHandler.handle(SecurityHandler.java: 216) at org.mortbay.jetty.servlet.SessionHandler.handle(SessionHandler.java: 182) at org.mortbay.jetty.handler.ContextHandler.handle(ContextHandler.java: 765) at org.mortbay.jetty.webapp.WebAppContext.handle(WebAppContext.java: 418) at com.google.apphosting.utils.jetty.DevAppEngineWebAppContext.handle(DevAppEngineWebAppContext.java: 70) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java: 152) at com.google.appengine.tools.development.JettyContainerService $ApiProxyHandler.handle(JettyContainerService.java:349) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java: 152) at org.mortbay.jetty.Server.handle(Server.java:326) at org.mortbay.jetty.HttpConnection.handleRequest(HttpConnection.java: 542) at org.mortbay.jetty.HttpConnection $RequestHandler.content(HttpConnection.java:938) at org.mortbay.jetty.HttpParser.parseNext(HttpParser.java:755) at org.mortbay.jetty.HttpParser.parseAvailable(HttpParser.java:218) at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:404) at org.mortbay.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java: 409) at org.mortbay.thread.QueuedThreadPool $PoolThread.run(QueuedThreadPool.java:582) Caused by: java.lang.ClassNotFoundException: com.google.gdata.client.calendar.CalendarService at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:315) at com.google.appengine.tools.development.IsolatedAppClassLoader.loadClass(IsolatedAppClassLoader.java: 151) at java.lang.ClassLoader.loadClass(ClassLoader.java:250) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:398) ... 33 more What can I do??

  Right now I'm running Wordpress w/ W3 Cache on nginx with varnish front end. I'm trying to use the WP Touch Pro plugin for wordpress to display mobile sites, but it is not working.

• Does JUnit4 testclasses require a public no arg constructor?

  I have a test class, written in JUnit4 syntax, that can be run in eclipse with the "run as junit test" option without failing.

• Why is the latency on one LVM volume consistently higher?

  - by David Schmitt

  I've got a server with LVM over RAID1. One of the volumes has a consistently higher IO latency (as measured by the diskstats_latency munin plugin) than the other volumes from the same group. As you can see, the dark orange /root volume has consistently high IO latency. Actually ten times the average latency of the physical devices. It also has the highest Min and Max values. My main concern are not the peaks, which occur under high load, but the constant load on (semi-)idle. The server is running Debian Squeeze with the VServer kernel and has four VServer containers and one KVM guest. I'm looking for ways to fix - or at least understand - this situation. Here're some parts of the system configuration: root@kvmhost2:~# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/system--host-root 19G 3.8G 14G 22% / tmpfs 16G 0 16G 0% /lib/init/rw udev 16G 224K 16G 1% /dev tmpfs 16G 0 16G 0% /dev/shm /dev/md0 942M 37M 858M 5% /boot /dev/mapper/system--host-isos 28G 19G 8.1G 70% /srv/isos /dev/mapper/system--host-vs_a 30G 23G 6.0G 79% /var/lib/vservers/a /dev/mapper/system--host-vs_b 5.0G 594M 4.1G 13% /var/lib/vservers/b /dev/mapper/system--host-vs_c 5.0G 555M 4.2G 12% /var/lib/vservers/c /dev/loop0 4.4G 4.4G 0 100% /media/debian-6.0.0-amd64-DVD-1 /dev/loop1 4.4G 4.4G 0 100% /media/debian-6.0.0-i386-DVD-1 /dev/mapper/system--host-vs_d 74G 55G 16G 78% /var/lib/vservers/d root@kvmhost2:~# cat /proc/mounts rootfs / rootfs rw 0 0 none /sys sysfs rw,nosuid,nodev,noexec,relatime 0 0 none /proc proc rw,nosuid,nodev,noexec,relatime 0 0 none /dev devtmpfs rw,relatime,size=16500836k,nr_inodes=4125209,mode=755 0 0 none /dev/pts devpts rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000 0 0 /dev/mapper/system--host-root / ext3 rw,relatime,errors=remount-ro,data=ordered 0 0 tmpfs /lib/init/rw tmpfs rw,nosuid,relatime,mode=755 0 0 tmpfs /dev/shm tmpfs rw,nosuid,nodev,relatime 0 0 fusectl /sys/fs/fuse/connections fusectl rw,relatime 0 0 /dev/md0 /boot ext3 rw,sync,relatime,errors=continue,data=ordered 0 0 /dev/mapper/system--host-isos /srv/isos ext3 rw,relatime,errors=continue,data=ordered 0 0 /dev/mapper/system--host-vs_a /var/lib/vservers/a ext3 rw,relatime,errors=continue,data=ordered 0 0 /dev/mapper/system--host-vs_b /var/lib/vservers/b ext3 rw,relatime,errors=continue,data=ordered 0 0 /dev/mapper/system--host-vs_c /var/lib/vservers/c ext3 rw,relatime,errors=continue,data=ordered 0 0 /dev/loop0 /media/debian-6.0.0-amd64-DVD-1 iso9660 ro,relatime 0 0 /dev/loop1 /media/debian-6.0.0-i386-DVD-1 iso9660 ro,relatime 0 0 /dev/mapper/system--host-vs_d /var/lib/vservers/d ext3 rw,relatime,errors=continue,data=ordered 0 0 root@kvmhost2:~# cat /proc/mdstat Personalities : [raid1] md1 : active raid1 sda2[0] sdb2[1] 975779968 blocks [2/2] [UU] md0 : active raid1 sda1[0] sdb1[1] 979840 blocks [2/2] [UU] unused devices: <none> root@kvmhost2:~# iostat -x Linux 2.6.32-5-vserver-amd64 (kvmhost2) 06/28/2012 _x86_64_ (8 CPU) avg-cpu: %user %nice %system %iowait %steal %idle 3.09 0.14 2.92 1.51 0.00 92.35 Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sda 23.25 161.12 7.46 37.90 855.27 1596.62 54.05 0.13 2.80 1.76 8.00 sdb 22.82 161.36 7.36 37.66 850.29 1596.62 54.35 0.54 12.01 1.80 8.09 md0 0.00 0.00 0.00 0.00 0.14 0.02 38.44 0.00 0.00 0.00 0.00 md1 0.00 0.00 53.55 198.16 768.01 1585.25 9.35 0.00 0.00 0.00 0.00 dm-0 0.00 0.00 0.48 20.21 16.70 161.71 8.62 0.26 12.72 0.77 1.60 dm-1 0.00 0.00 3.62 10.03 28.94 80.21 8.00 0.19 13.68 1.59 2.17 dm-2 0.00 0.00 0.00 0.00 0.00 0.00 9.17 0.00 9.64 6.42 0.00 dm-3 0.00 0.00 6.73 0.41 53.87 3.28 8.00 0.02 3.44 0.12 0.09 dm-4 0.00 0.00 17.45 18.18 139.57 145.47 8.00 0.42 11.81 0.76 2.69 dm-5 0.00 0.00 2.50 46.38 120.50 371.07 10.06 0.69 14.20 0.46 2.26 dm-6 0.00 0.00 0.02 0.10 0.67 0.81 12.53 0.01 75.53 18.58 0.22 dm-7 0.00 0.00 0.00 0.00 0.00 0.00 7.99 0.00 11.24 9.45 0.00 dm-8 0.00 0.00 22.69 102.76 407.25 822.09 9.80 0.97 7.71 0.39 4.95 dm-9 0.00 0.00 0.06 0.08 0.50 0.62 8.00 0.07 481.23 11.72 0.16 root@kvmhost2:~# ls -l /dev/mapper/ total 0 crw------- 1 root root 10, 59 May 11 11:19 control lrwxrwxrwx 1 root root 7 Jun 5 15:08 system--host-kvm1 -> ../dm-4 lrwxrwxrwx 1 root root 7 Jun 5 15:08 system--host-kvm2 -> ../dm-3 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-isos -> ../dm-2 lrwxrwxrwx 1 root root 7 May 11 11:19 system--host-root -> ../dm-0 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-swap -> ../dm-9 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-vs_d -> ../dm-8 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-vs_b -> ../dm-6 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-vs_c -> ../dm-7 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-vs_a -> ../dm-5 lrwxrwxrwx 1 root root 7 Jun 5 15:08 system--host-kvm3 -> ../dm-1 root@kvmhost2:~#

• Generics and Performance question.

  - by Tarmon

  Hey Everyone, I was wondering if anyone could look over a class I wrote, I am receiving generic warnings in Eclipse and I am just wondering if it could be cleaned up at all. All of the warnings I received are surrounded in ** in my code below. The class takes a list of strings in the form of (hh:mm AM/PM) and converts them into HourMinute objects in order to find the first time in the list that comes after the current time. I am also curious about if there are more efficient ways to do this. This works fine but the student in me just wants to find out how I could do this better. public class FindTime { private String[] hourMinuteStringArray; public FindTime(String[] hourMinuteStringArray){ this.hourMinuteStringArray = hourMinuteStringArray; } public int findTime(){ HourMinuteList hourMinuteList = convertHMStringArrayToHMArray(hourMinuteStringArray); Calendar calendar = new GregorianCalendar(); int hour = calendar.get(Calendar.HOUR_OF_DAY); int minute = calendar.get(Calendar.MINUTE); HourMinute now = new HourMinute(hour,minute); int nearestTimeIndex = findNearestTimeIndex(hourMinuteList, now); return nearestTimeIndex; } private int findNearestTimeIndex(HourMinuteList hourMinuteList, HourMinute now){ HourMinute current; int position = 0; Iterator<HourMinute> iterator = **hourMinuteList.iterator()**; while(iterator.hasNext()){ current = (HourMinute) iterator.next(); if(now.compareTo(current) == -1){ return position; } position++; } return position; } private static HourMinuteList convertHMStringArrayToHMArray(String[] times){ FindTime s = new FindTime(new String[1]); HourMinuteList list = s.new HourMinuteList(); String[] splitTime = new String[3]; for(String time : times ){ String[] tempFirst = time.split(":"); String[] tempSecond = tempFirst[1].split(" "); splitTime[0] = tempFirst[0]; splitTime[1] = tempSecond[0]; splitTime[2] = tempSecond[1]; int hour = Integer.parseInt(splitTime[0]); int minute = Integer.parseInt(splitTime[1]); HourMinute hm; if(splitTime[2] == "AM"){ hm = s.new HourMinute(hour,minute); } else if((splitTime[2].equals("PM")) && (hour < 12)){ hm = s.new HourMinute(hour + 12,minute); } else{ hm = s.new HourMinute(hour,minute); } **list.add(hm);** } return list; } class **HourMinuteList** extends **ArrayList** implements RandomAccess{ } class HourMinute implements **Comparable** { int hour; int minute; public HourMinute(int hour, int minute) { setHour(hour); setMinute(minute); } int getMinute() { return this.minute; } String getMinuteString(){ if(this.minute < 10){ return "0" + this.minute; }else{ return "" + this.minute; } } int getHour() { return this.hour; } void setHour(int hour) { this.hour = hour; } void setMinute(int minute) { this.minute = minute; } @Override public int compareTo(Object aThat) { if (aThat instanceof HourMinute) { HourMinute that = (HourMinute) aThat; if (this.getHour() == that.getHour()) { if (this.getMinute() > that.getMinute()) { return 1; } else if (this.getMinute() < that.getMinute()) { return -1; } else { return 0; } } else if (this.getHour() > that.getHour()) { return 1; } else if (this.getHour() < that.getHour()) { return -1; } else { return 0; } } return 0; } } If you have any questions let me know. Thanks, Rob

• Java Applet Deployment, ClassNotFoundException (primary class)

  - by Matt

  This is driving me up the wall. I have checked and rechecked spelling and paths. I have tried just about every combination of paths, including relative, absolute, and full http paths. I continue to get the following error when trying to load a Java applet: java.lang.ClassNotFoundException: AppletClient.class at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Unknown Source) at sun.plugin2.applet.Plugin2Manager.createApplet(Unknown Source) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Exception: java.lang.ClassNotFoundException: AppletClient.class The HTML used to load the applet: <applet width="100" height="100" archive="applet/myapplet.jar, applet/applet_dependency.jar" code="AppletClient.class"> <param value="blahblah" name="username"> <param value="false" name="codebase_lookup"> </applet> The applet is in a relative directory, "applet", from the path of the current page. I have unzipped the jar file and can see AppletClient.class. Also, in the source of the project, it is spelled that way (casing and all). I have tried with/without the parameters. I have changed the names of the archive jars in the applet include tag just to see if I get a different error for bad file names (same error). I have manually done GETs on the jars to make sure the server is responding to the requests (it is). I have tried with and without the codebase tag, with all different varieties of paths (start getting bad "magic number" errors on those). I know that this error sometimes pops up when a dependency fails to load, so it can be misleading, but all dependencies are present, accounted for, and are fetchable via manual GETs. Between each and every attempt I always clear my cache in FireFox. These problems are reproduced in IE8 and Chrome as well. Per my Java Console from the browser, I am running Java Plug-in 1.6.0_20. This is from the same machine that I develop the applet on, which runs fine via Eclipse. Finally, I kicked on Fiddler2, and I don't see a single request for the jar files anywhere The host site is running from my Visual Studio debugger, so it's running on localhost. But I see the requests for all the other resources on Fiddler. Just... no Jars. ANYWHERE. I clear the log, cleared my browser cache, and did a ctrl-R refresh. And still, not a single Jar request on the Fiddler log. I even did a delayed write (with JS) of the applet tag after the page loaded, once all the Fiddler activity slowed down. The element gets written to the document (and I can see the 100x100 Java error window), but not a single request shows up on Fiddler. Any suggestions, before I go crawl into the corner and cry myself to sleep? EDIT: From the Java console, if I hit "l" (el) to "dump classloader list", I see something that looks like this: Live entry: key=http://localhost:55446/BaseWebSite/,http://localhost:55446/BaseWebSite/applet/myappliet.jar, http://localhost:55446/BaseWebSite/applet/applet_dependency.jar, refCount=1, threadGroup=sun.plugin2.applet.Applet2ThreadGroup[name=http://localhost:55446/BaseWebSite/-threadGroup,maxpri=4]
