• Can I do my own HTTP header attribute?

  - by wokena

  Hi, can I make my own headers in HTTP request? e.g. This is normal HTTP request GET / HTTP/1.1 Host: google.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT x.x; xx; rv:x.x.x.x) xxx Firefox/3.0.10 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: xx,en-us;q=0.7,en;q=0.3 Accept-Encoding: gzip,deflate Accept-Charset: windows-1250,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive and this is header with my "attribute" GET / HTTP/1.1 Host: google.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT x.x; xx; rv:x.x.x.x) xxx Firefox/3.0.10 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: xx,en-us;q=0.7,en;q=0.3 Accept-Encoding: gzip,deflate Accept-Charset: windows-1250,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive Name: John and I will have "attribute" in server response. I'll use "attrubutes" in HTTP headers instead of sessions attributes... BTW.Sorry for my english... ;)

• Javascript: addClassName if input is checked and removeClassName if it was un-checked

  - by BoDiE2003

  Im trying to select all the li tags of the document and check if it hasClassName('yes') so if it has, it will remove it. But im having a TypeError: Object [object HTMLLIElement], has no method 'hasClassName' error. This is the DOM method: document.observe("dom:loaded", function() { $(document.body).select('input').each(function(element) { element.observe('click', function() { init(); }); init(); }); }); The previous code will take the init fuction and check the if there are checked inputs and add them the 'yes' class name, but if I un-check those inputs, the class remains. This is the funcion that Im trying to do dynamic (add and remove class 'yes'); function init() { $(document.body).select('input').each(function(element) { if (element.checked) { element.up('li').addClassName('yes'); } if ($(document.body).select('li').hasClassName('yes')) { element.removeClassName('yes'); } }) } Can you help me solving the last part of this function, so the removeclassname method will work? Thank you

• maven-release-plugin: Perform fails with 'working directory "...workspace\target\checkout\workspace"

  - by Ed

  Hi, I have maven project that fails when release:perform is called, though release;prepare works as expected. I have found the bug report (below) which certainly seems to resemble the issue I have but not entirely sure I understand the problem: MRELEASE516 The last few lines of output I get: [INFO] Executing: cmd.exe /X /C "p4 -d E:\hudson\jobs\myHudsonJob\workspace\target\checkout -p 10.20.0.38:1666 client -d myProjectWorkspace-MavenSCM-E:\hudson\jobs\myHudsonJob\workspace\target\checkout" [INFO] Executing goals 'deploy'... [WARNING] Base directory is a file. Using base directory as POM location. [WARNING] Maven will be executed in interactive mode, but no input stream has been configured for this MavenInvoker instance. [INFO] ------------------------------------------------------------------------ [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] Error executing Maven. Working directory "E:\hudson\jobs\myHudsonJob\workspace\target\checkout\workspace" does not exist! From reading the bug report the possible cause of the error is related to my modules' structure, I've tried to outline it below: /workspace | |+ pom.xml (root pom whose parent is the build pom, | calling release:perform on this pom) | [Modules: moduleA and moduleB] | |- moduleA |+ pom.xml (parent is also build pom) |+ build/pom.xml (the build pom - no custom parent) |- moduleB |+ pom.xml (parent is build pom) It seems that the root pom should be in some common directory inside 'workspace' from the error but tried that and doesn't work, nor make sense as to why I need it. What does the warning Base directory is a file want me to do instead?! It then figures that the base directory is workspace which then means the working directory is not found...any ideas? Thanks in advance.

• When should I observe javascript events on window vs. document vs. document.body?

  - by brahn

  I'm using prototype.js for my web app, and I have everything running on chrome, safari, and firefox. I am now working on IE8 compatibility. As I've been debugging in IE, I've noticed that there are javascript events for which I have previously set an observer on the window, e.g. Event.observe(window, eventType, function () {...}); (where eventType might be "dom:loaded", "keypress", etc.) and it works just fine in Chrome/Safari/Firefox. However, in IE the observer never fires. In at least some cases I could get this to work on IE by instead placing the observer on something other than window, e.g. document (in the case of "dom:loaded") or document.body (in the case of "keypress"). However, this is all trial-and-error. Is there some more systematic way to determine where to place these observers such that the results will be cross-browser compatible? Thanks!

• How to use Struts 2 with JFreeChart?

  Firstly, I went here ( http://code.google.com/p/struts2-examples/downloads/list and I downloaded Hello_World_Struts2_Mvn.zip) and I run that example. After that, I went here (http://struts.apache.org/2.x/docs/jfreechart-plugin.html), I add the dependencies for commons-lang-2.5.jar, jcommon-1.0.16.jar and jfreechart-1.0.13.jar and I modify the example downloaded from code.google.com to see how JFreeChart is working, but I receive this error: Unable to load configuration. - action - file:/C:/.../untitled_war_exploded/WEB-INF/classes/struts.xml:34:67 Caused by: Error building results for action createChart in namespace - action - file:/C:/.../out/artifacts/untitled_war_exploded/WEB-INF/classes/struts.xml:34:67 Caused by: There is no result type defined for type 'chart' mapped with name 'success'.

• How to transform SoapFault to SoapMessage via Interceptor in CXF?

  - by Michal Mech

  I have web-service created and configured via Spring and CXF. See beans below: <?xml version="1.0" encoding="UTF-8"?> <beans <!-- ommited -->> <import resource="classpath:META-INF/cxf/cxf.xml" /> <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" /> <import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> <bean id="internalActService" class="package.InternalActServiceImpl" /> <jaxws:endpoint implementor="#internalActService" address="/InternalActService"> <jaxws:properties> <entry key="schema-validation-enabled" value="true" /> </jaxws:properties> <jaxws:outFaultInterceptors> <bean class="package.InternalActServiceFaultOutInterceptor" /> </jaxws:outFaultInterceptors> </jaxws:endpoint> </beans> As can you see I added schema validation to my web service. But CXF throws SoapFault when request is not corresponding with schema. I want to send to the client SoapMessage instead of SoapFault, that's why I added outFaultInterceptors. My question is how to transform SoapFault to SoapMessage? I've made few tries but I don't know how to implement outFaultInterceptor.

• How to create a JAX-RS service where the sub-resource @Path doesn't have a leading slash

  - by Matt

  I've created a JAX-RS service (MyService) that has a number of sub resources, each of which is a subclass of MySubResource. The sub resource class being chosen is picked based on the parameters given in the MyService path, for example: @Path("/") @Provides({"text/html", "text/xml"}) public class MyResource { @Path("people/{id}") public MySubResource getPeople(@PathParam("id") String id) { return new MyPeopleSubResource(id); } @Path("places/{id}") public MySubResource getPlaces(@PathParam("id") String id) { return new MyPlacesSubResource(id); } } where MyPlacesSubResource and MyPeopleSubResource are both sub-classes of MySubResource. MySubResource is defined as: public abstract class MySubResource { protected abstract Results getResults(); @GET public Results get() { return getResults(); } @GET @Path("xml") public Response getXml() { return Response.ok(getResults(), MediaType.TEXT_XML_TYPE).build(); } @GET @Path("html") public Response getHtml() { return Response.ok(getResults(), MediaType.TEXT_HTML_TYPE).build(); } } Results is processed by corresponding MessageBodyWriters depending on the mimetype of the response. While this works it results in paths like /people/Bob/html or /people/Bob/xml where what I really want is /people/Bob.html or /people/Bob.xml Does anybody know how to accomplish what I want to do?

• generating and unmarshalling java classes while unmarshalling input contains a DTD

  - by Hans Westerbeek

  Hi, For a Spring-based project, I have the following situation to solve: I have XML files coming in whose contents I will have to parse at runtime. Those XML files come with a DTD reference. I need to generate the classes that the unmarshaller churns out using the right at build time, using the Maven2 plugin for the unmarshalling library of choice. This is also not very hard to do, once I have generated an XSD from the DTD. I want to use spring-oxm's UnMarshaller interface to do the unmarshalling at runtime. This I understand how to do. The xml files come in with a DTD reference, and all unmarshalling libraries out there want to do unmarshalling based on an XSD. Now, as described in the castor documentation, I can convert the DTD to an XSD and keep it on the classpath. However, when an actual XML file comes into the system it will still have that DTD reference at the top, and there's nothing I can really do about that (except for string replacing which feels hacky in this case). Will this cause the unmarshaller, like Castor to fail? Am I right in suspecting that this DTD reference will cause the unmarshalling to fail? Could I do pure DTD-based unmarshalling? Or can this somehow be prevented by providing detailed configuration to the unmarshaller? Until now, I have tried castor, xmlbeans and xstream. Which would fit my purposes best? Has anyone else been in this situation? Did you also end up just doing manual DOM or SAX parsing?

• How can I provide users with the functionality of the DBUnit DatabaseOperation methods from a web in

  - by reckoner

  I am currently updating a java-based web application which allows database developers to create stored procedure regression test suites for database testing. Currently, for test setup, execution and clean-up stages, the user is provided with text boxes where they are able to enter SQL code which is executed by the isql command. I would like to extend the application to use DB Unit’s DatabaseOperation methods to provide more ways to setup the state of the database than just SQL statements. The main reason for using Db Unit rather than just SQL statements is to be able to create and store xml and xls DataSets on a server where they can be associated with their test cases and used for data setup. My question is: How can I provide users with the functionality of the DBUnit DatabaseOperation methods from a web interface? I have considered: Creating a simple programming language and a parser to read some simple syntax involving the DB Unit method names which accept a parameter being the file location to an xml or xls DataSet. I was thinking of allowing the user to register the files they need with the web app which would catalogue them and provide each file with an identifier which could passed as a parameter to the methods in this simple programming language. Creating an XML DTD which provides the user with the ability to specify operations and parameters. If I went this approach, how can I execute the methods and their parameters that I parse from the XML document? Creating a table in the database which stores the method and a FK relation to a catalogued DataSet file, however I don’t think this would be good solution due to the fact that data entry would be tedious. Thanks for your help.

• Database Functional Programming in Clojure

  - by Ralph

  "It is tempting, if the only tool you have is a hammer, to treat everything as if it were a nail." - Abraham Maslow I need to write a tool to dump a large hierarchical (SQL) database to XML. The hierarchy consists of a Person table with subsidiary Address, Phone, etc. tables. I have to dump thousands of rows, so I would like to do so incrementally and not keep the whole XML file in memory. I would like to isolate non-pure function code to a small portion of the application. I am thinking that this might be a good opportunity to explore FP and concurrency in Clojure. I can also show the benefits of immutable data and multi-core utilization to my skeptical co-workers. I'm not sure how the overall architecture of the application should be. I am thinking that I can use an impure function to retrieve the database rows and return a lazy sequence that can then be processed by a pure function that returns an XML fragment. For each Person row, I can create a Future and have several processed in parallel (the output order does not matter). As each Person is processed, the task will retrieve the appropriate rows from the Address, Phone, etc. tables and generate the nested XML. I can use a a generic function to process most of the tables, relying on database meta-data to get the column information, with special functions for the few tables that need custom processing. These functions could be listed in a map(table name -> function). Am I going about this in the right way? I can easily fall back to doing it in OO using Java, but that would be no fun. BTW, are there any good books on FP patterns or architecture? I have several good books on Clojure, Scala, and F#, but although each covers the language well, none look at the "big picture" of function programming design.

• How does jQuery .data() work?

  - by kazanaki

  My Javascript knowledge is pretty limited. Instead of asking several javascript questions I got the "message" from Stack overflow and started using jQuery right away in order to save me some time. However several times I do not undestand the "magic" behind jQuery and I would love to learn the details. I want to use .data() in my application. The examples are very helpful. I do not understand however WHERE these values are stored. I inspect the webpage with Firebug and as soon as .data() saves an object to a dom element, I do not see any change in Firebug (either HTML or Dom tabs). I tried to look at jQuery source, but it is very advanced for my Javascript knowledge and I lost myself. So the question is: Where do the values stored by jQuery.data() actually go? Can I inspect/locate/list/debug them using a tool?

• In WebKitGtk+, how can I access parameters in an event listener?

  - by Matthew

  Here is an example in javascript of what I want to do: function handleDragStart(e) { e.dataTransfer.effectAllowed = 'move'; e.dataTransfer.setData('text/plain', 'some data'); } var dragSource = document.querySelector('#dragSource'); dragSource.addEventListener('dragstart', handleDragStart, false, null); But I am having trouble translating this to a GLib-based system. Here is an example in Vala: void on_dragstart(EventTarget event_target) { // How can I access the equivalent of e.dataTransfer? } WebKit.WebView web_view = ... WebKit.DOM.Document document = web_view.get_dom_document(); WebKit.DOM.Element drag_source = document.query_selector('#dragSource'); drag_source.add_event_listener("dragstart", (Callback) on_dragstart, false, null); While I am using Vala, an answer in any language interacting with WebKitGtk+ directly would be helpful.

• Are there solutions for streamlining the update of legacy code in multiple places?

  - by ccomet

  I'm working in some old code which was originally designed for handling two different kinds of files. I was recently tasked with adding a new kind of file to this code. Most of my problems were solved by filling out an extensive XML file with a new entry that handled everything from what lists were named to how the file is written in plural lower case. But this ended up being insufficient, as there were maybe 50 different places in 24 different code files where I had to update hardcoded switch-statements that only branched for the original two file types. Unfortunately there is no consistency in this; there are methods which operate half from the XML file, and half off of hardcode. Some of the files which look like they would operate off of the XML file don't, and some that I would expect that I'd need to update the hardcode don't need it. So the only way to find the majority of these is to run through testing the whole system when only part of it is operational, finding that one step to fix (when I'm lucky that error logging actually tells me what is going on), and then running the whole thing again. This wastes time testing the parts of the code which are already confirmed to work, time better spent testing the new parts I have to add on top of it all. It's a hassle and a half, and to my luck I can expect that I will have to add yet another new kind of file in the near future. Are there any solutions out there which can aid in this kind of endeavour? Something which I can input some parameters of current features, document what points in a whole code project actually need to be updated, and run something nice the next time I need to add a new feature to the code. It needn't even be fully automated, something that'll help me navigate straight to the specific points in everything and maybe even record what kind of parameters need to be loaded. Doubt it matters specifically, but the code is comprised of ASP.NET pages, some ASP.NET controls, hundreds of C# code files, and a handful of additional XML files. It's all currently in a couple big Visual Studio 2008 projects.

• Tabbed javascript widget for a Rails app

  - by neilc

  A user registers on our Rails app and they're given javascript to embed a widget in their website. The widget has a tabbed interface, like the JQuery tabs http://stilbuero.de/jquery/tabs_3/. iFrames have been tested, but the widget form factor and cross-domain policy negates the use of iframes. The widget is very dynamic and will often update the DOM with new content - and because of cross-domain policy, it looks as though JSONP is necessary. I understand that 'widget.js.erb' needs to create the widget layout, reference a stylesheet, render the tabs, etc - but once a tab is clicked, how does the widget request the content from the Rails app and render it in the DOM?

Which is returning lines that contain 'onemyndseye@localhost' and removing it so that only the following is returned: <input type="checkbox" id="D1" name="D1" /><a href="http://www.linux.com/rss/feeds.php">http://www.linux.com/rss/feeds.php</a> <br /> <input type="checkbox" id="D2" name="D2" /><a href="http://www.ubuntu.com/rss.xml">http://www.ubuntu.com/rss.xml</a> <br /> Thanks to the wonderful users of this site Ive gotten this far and can even return just the links but I am having trouble getting the rest... Its important that the complete <input> tags are returned EXACTLY as shown above as the id and name values will need to be passed back to the original form in post data later on. Thanks in advance!

• C# Web Service gets stuck waiting for lock, does not return

  - by blue

  We have a C#(2.0) application which talks to our server(in java) via web services. Lately we have started seeing following behavior in (ONLY)one of our lab machines(XP): Once in a while(every few days), one of the webservice request will just get stuck, will not return or timeout. Following is the stacktrace where it seem to be stuck. Have no clue what is going on here. Any pointer would be of great help.
