  • Featureful commercial text editors?

    - by wrp
    I'm willing to buy tools if they add genuine value over a FOSS equivalent. One thing I wouldn't mind having is an editor with the power of Emacs, but made more user-friendly. There seem to be several commercial editors out there, but I can't find much discussion of them online. Maybe it's because the kind of people who use commercial software don't have time to do much blogging. ;-) If you have used any, what was your evaluation? I'd especially like to hear how you would compare them to Emacs. I'm thinking of editors like VEDIT, Boxer, Crisp, UltraEdit, SlickEdit, etc. To get things started, I tried EditPad Pro because I needed something on a Win98SE box. I was attracted by its powerful support for regexps, but I didn't use it for long. One annoyance was that find-in-files was only available in a separate product you had to buy. The main problem, though, was stability. It sometimes hung and I lost a few files because it corrupted them while editing. After a couple weeks, I found that I was avoiding using it, so I just uninstalled. Edit: Ah...I need to remove some ambiguity. With reference to Emacs, "power" often means its potential for customization. This malleability comes from having an architecture in which most of the functionality is written in a scripting language that runs on a compiled core. Emacs (with elisp) is by far the most widely known such system among home users, but there have been other heavily used editors such as Freemacs (MINT), JED (S-Lang), XEDIT (Rexx), ADAM (TPU), and SlickEdit (Slick-C). In this case, by "power" I'm not referring to extensibility but to realized features. There are three main areas which I think a commercial text editor might be an improvement over Emacs: Stability The only apps I regularly use on Linux that give me flaky behavior are Emacs, Gedit, and Geany. On Windows, I like the look and features of Notepad++, but I find it extremely unstable, especially if I try to use the plugins. Whatever I happen to be doing, I'm using some text editor practically all day long. If I could switch to an editor that never gave me problems, it would definitely lower my stress level. Tools When I started using Emacs, I searched the manual cover to cover to gleam ideas for clever, useful things I could do with it. I'd like to see lots of useful features for editing code, based on detailed knowledge of what the system can do and the accumulated feedback of users. Polish The rule of threes goes that if you develop something for yourself, it's three times harder to make it usable in-house, and three times harder again to make it a viable product for sale. It's understandable, but free software development doesn't seem to benefit from much usability testing. BTW, texteditors.org is a fantastic resource for researching text editors.

  • Get UiBinder widget to display inline instead of block

    - by Steve Armstrong
    I'm trying to get my UiBinder-defined widget to display inline, but I can't. My current code is: <ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder' xmlns:g='urn:import:com.google.gwt.user.client.ui'> <ui:style> .section { border: 1px solid #000000; width: 330px; padding: 5px; display: run-in; } </ui:style> <g:HTMLPanel> <div class="{style.section}"> <div ui:field="titleSpan" class="{style.title}" /> <div class="{style.contents}"> <g:VerticalPanel ui:field="messagesPanel" /> </div> </div> </g:HTMLPanel> </ui:UiBinder> This works fine in terms of how the widget looks internally, but I want to throw a bunch of these widgets into a FlowPanel and have them flow when the window is resized. The HTMLPanel is a div, but I can't get the display attribute to assign. I can't force the style name, since the following throws an error: <g:HTMLPanel styleNames="{style.section}"> And I can assign an additional style, but it doesn't apply the display setting. <g:HTMLPanel addStyleNames="{style.section}"> This displays the border and sets the size, as expected, but it doesn't flow. Firebug shows the styles on the div are border, width, and padding, but no display. Is there a way to make a widget in UiBinder so that it'll display inline instead of block? And if so, can I make it compatible with having a VerticalPanel inside (can I do it without making the entire widget pure HTML without any GWT widgets)? PS: I saw question 2257924 but it hasn't had any answers lately, and he seems to be focused on getting a tag, not specifically getting inline layout. I don't care directly about , if I can just get the top-level tag for my widget to flow inline, I'm happy.

  • Android stream to Wowza

    - by Curtis Kiu
    I feel very confused about Android streaming to wowza. I am doing a video conference using rtmp cross-platform, but Android doesn't eat RTMP. Therefore I need to find another way to do it. Upstreaming I found a new open-source app called spydroid-ipcamera. It is using rtp, sending udp packets to computer, and opens it in vlc using the following sdp v=0 s=Unnamed m=video 5006 RTP/AVP 96 a=rtpmap:96 H264/90000 a=fmtp:96 packetization-mode=1;profile-level-id=420016;sprop-parameter-sets=Z0IAFukBQHsg,aM4BDyA=; But it can't work. Then I follow wowza tutorial and stream to it and then play again in VLC. That works! I wrote it in http://code.google.com/p/spydroid-ipcamera/issues/detail?id=2 However when I want to add audio in the packet, it fails to work. I change to code in http://code.google.com/p/spydroid-ipcamera/source/browse/trunk/src/net/mkp/spydroid/CameraStreamer.java mr.setAudioSource(MediaRecorder.AudioSource.MIC); mr.setVideoSource(MediaRecorder.VideoSource.CAMERA); mr.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4); mr.setVideoFrameRate(20); mr.setVideoSize(640, 480); mr.setAudioEncoder(MediaRecorder.AudioEncoder.AAC); mr.setVideoEncoder(MediaRecorder.VideoEncoder.H264); mr.setPreviewDisplay(holder.getSurface()); Then I thought that the problem should be in sdp, but I don't know how to due with sdp. I am streaming H.264/AAC with Mp4 Second I don't understand sdp. So how can I make video conference upstreaming part using this apps. Android ----(UDP Port:5006)----> PC (SDP file) and then Wowza read the SDP file ------> VLC I think in this way the system cannot handle more than 1 client. sdp can only hold 1 port, any idea or actually it wont' work? Also Wowza need to set the stream before we stream it, so does it mean that I should not follow this way to do it? Sorry my English is poor, I hope you guys understand.

  • How to inherit from DataAnnotations.ValidationAttribute (it appears SecureCritical under Visual Stud

    - by codetuner
    Hi, I have an [AllowPartiallyTrustedCallers] class library containing subtypes of the System.DataAnnotations.ValidationAttribute. The library is used on contract types of WCF services. In .NET 2/3.5, this worked fine. Since .NET 4.0 however, running a client of the service in the Visual Studio debugger results in the exception "Inheritance security rules violated by type: '(my subtype of ValidationAttribute)'. Derived types must either match the security accessibility of the base type or be less accessible." (System.TypeLoadException) The error appears to occure only when all of the following conditions are met: a subclass of ValidationAttribute is in an AllowPartiallyTrustedCallers assembly reflection is used to check for the attribute the Visual Studio hosting process is enabled (checkbox on Project properties, Debug tab) So basically, in Visual Studio.NET 2010: create a new Console project, add a reference to "System.ComponentModel.DataAnnotations" 4.0.0.0, write the following code: . using System; [assembly: System.Security.AllowPartiallyTrustedCallers()] namespace TestingVaidationAttributeSecurity { public class MyValidationAttribute : System.ComponentModel.DataAnnotations.ValidationAttribute { } [MyValidation] public class FooBar { } class Program { static void Main(string[] args) { Console.WriteLine("ValidationAttribute IsCritical: {0}", typeof(System.ComponentModel.DataAnnotations.ValidationAttribute).IsSecurityCritical); FooBar fb = new FooBar(); fb.GetType().GetCustomAttributes(true); Console.WriteLine("Press enter to end."); Console.ReadLine(); } } } Press F5 and you get the exception ! Press Ctrl-F5 (start without debugging), and it all works fine without exception... The strange thing is that the ValidationAttribute will or will not be securitycritical depending on the way you run the program (F5 or Ctrl+F5). As illustrated by the Console.WriteLine in the above code. But then again, this appear to happen with other attributes (and types?) too. Now the questions... Why do I have this behaviour when inheriting from ValidationAttribute, but not when inheriting from System.Attribute ? (Using Reflector I don't find special settings on the ValidationAttribute class or it's assembly) And what can I do to solve this ? How can I keep MyValidationAttribute inheriting from ValidationAttribute in an AllowPartiallyTrustedCallers assembly without marking it SecurityCritical, still using the new .NET 4 level 2 security model and still have it work using the VS.NET debug host (or other hosts) ?? Thanks a lot! Rudi

  • How much abstraction is too much?

    - by Daniel Bingham
    In an Object Oriented Program: How much abstraction is too much? How much is just right? I have always been a nuts and bolts kind of guy. I understood the concept behind high levels of encapsulation and abstraction, but always felt instinctively that adding too much would just confuse the program. I always tried to shoot for an amount of abstraction that left no empty classes or layers. And where in doubt, instead of adding a new layer to the hierarchy, I would try and fit something into the existing layers. However, recently I've been encountering more highly abstracted systems. Systems where everything that could require a representation later in the hierarchy gets one up front. This leads to a lot of empty layers, which at first seems like bad design. However, on second thought I've come to realize that leaving those empty layers gives you more places to hook into in the future with out much refactoring. It leaves you greater ability to add new functionality on top of the old with out doing nearly as much work to adjust the old. The two risks of this seem to be that you could get the layers you need wrong. In this case one would wind up still needing to do substantial refactoring to extend the code and would still have a ton of never used layers. But depending on how much time you spend coming up with the initial abstractions, the chance of screwing it up, and the time that could be saved later if you get it right - it may still be worth it to try. The other risk I can think of is the risk of over doing it and never needing all the extra layers. But is that really so bad? Are extra class layers really so expensive that it is much of a loss if they are never used? The biggest expense and loss here would be time that is lost up front coming up with the layers. But much of that time still might be saved later when one can work with the abstracted code rather than more low level code. So when is it too much? At what point do the empty layers and extra "might need" abstractions become overkill? How little is too little? Where's the sweet spot? Are there any dependable rules of thumb you've found in the course of your career that help you judge the amount of abstraction needed?

  • practical security ramifications of increasing WCF clock skew to more than an hour

    - by Andrew Patterson
    I have written a WCF service that returns 'semi-private' data concerning peoples name, addresses and phone numbers. By semi-private, I mean that there is a username and password to access the data, and the data is meant to be secured in transit. However, IMHO noone is going to expend any energy trying to obtain the data, as it is mostly available in the public phone book anyway etc. At some level, the security is a bit of security 'theatre' to tick some boxes imposed on us by government entities. The client end of the service is an application which is given out to registered 'users' to run within their own IT setups. We have no control over the IT of the users - and in fact they often tell us to 'go jump' if we put too many requirements on their systems. One problem we have been encountering is numerous users that have system clocks that are not accurate. This can either be caused by a genuine slow/fast clocks, or more than likely a timezone or daylight savings zone error (putting their machine an hour off the 'real' time). A feature of the WCF bindings we are using is that they rely on the notion of time to detect replay attacks etc. <wsHttpBinding> <binding name="normalWsBinding" maxBufferPoolSize="524288" maxReceivedMessageSize="655360"> <reliableSession enabled="false" /> <security mode="Message"> <message clientCredentialType="UserName" negotiateServiceCredential="false" algorithmSuite="Default" establishSecurityContext="false" /> </security> </binding> </wsHttpBinding> The inaccurate client clocks cause security exceptions to be thrown and unhappy users. Other than suggesting users correct their clocks, we know that we can increase the clock skew of the security bindings. http://www.danrigsby.com/blog/index.php/2008/08/26/changing-the-default-clock-skew-in-wcf/ My question is, what are the real practical security ramifications of increasing the skew to say 2 hours? If an attacker can perform some sort of replay attack, why would a clock skew window of 5 minutes be necessarily safer than 2 hours? I presume performing any attack with security mode of 'message' requires more than just capturing some data at a proxy and sending the data back in again to 'replay' the call? In a situation like mine where data is only 'read' by the users, are there indeed any security ramifications at all to allowing 'replay' attacks?

  • NetBeans not liking libraries in lib-src

    - by DJTripleThreat
    I'm working on a project with a group that is using Eclipse, but I'm using Netbeans. Up until today this wasn't an issue. When updating from the repo they have added some source code as a library under a directory called /lib-src. When I try to compile the code I get an error that it can't find certain packages... these are the packages under /lib-src. Using NetBeans I can add the library as a folder so now the references to those packages are happy. However, I'm getting this new error when compiling: UNEXPECTED TOP-LEVEL ERROR: java.lang.OutOfMemoryError: Java heap space at java.util.HashMap.addEntry(HashMap.java:753) at java.util.HashMap.put(HashMap.java:385) at com.android.dx.dex.file.ClassDataItem.addStaticField(ClassDataItem.java:134) at com.android.dx.dex.file.ClassDefItem.addStaticField(ClassDefItem.java:280) at com.android.dx.dex.cf.CfTranslator.processFields(CfTranslator.java:159) at com.android.dx.dex.cf.CfTranslator.translate0(CfTranslator.java:130) at com.android.dx.dex.cf.CfTranslator.translate(CfTranslator.java:85) at com.android.dx.command.dexer.Main.processClass(Main.java:297) at com.android.dx.command.dexer.Main.processFileBytes(Main.java:276) at com.android.dx.command.dexer.Main.access$100(Main.java:56) at com.android.dx.command.dexer.Main$1.processFileBytes(Main.java:228) at com.android.dx.cf.direct.ClassPathOpener.processOne(ClassPathOpener.java:134) at com.android.dx.cf.direct.ClassPathOpener.processDirectory(ClassPathOpener.java:190) at com.android.dx.cf.direct.ClassPathOpener.processOne(ClassPathOpener.java:122) at com.android.dx.cf.direct.ClassPathOpener.processDirectory(ClassPathOpener.java:190) at com.android.dx.cf.direct.ClassPathOpener.processOne(ClassPathOpener.java:122) at com.android.dx.cf.direct.ClassPathOpener.processDirectory(ClassPathOpener.java:190) at com.android.dx.cf.direct.ClassPathOpener.processOne(ClassPathOpener.java:122) at com.android.dx.cf.direct.ClassPathOpener.processDirectory(ClassPathOpener.java:190) at com.android.dx.cf.direct.ClassPathOpener.processOne(ClassPathOpener.java:122) at com.android.dx.cf.direct.ClassPathOpener.processDirectory(ClassPathOpener.java:190) at com.android.dx.cf.direct.ClassPathOpener.processOne(ClassPathOpener.java:122) at com.android.dx.cf.direct.ClassPathOpener.processDirectory(ClassPathOpener.java:190) at com.android.dx.cf.direct.ClassPathOpener.processOne(ClassPathOpener.java:122) at com.android.dx.cf.direct.ClassPathOpener.processDirectory(ClassPathOpener.java:190) at com.android.dx.cf.direct.ClassPathOpener.processOne(ClassPathOpener.java:122) at com.android.dx.cf.direct.ClassPathOpener.process(ClassPathOpener.java:108) at com.android.dx.command.dexer.Main.processOne(Main.java:245) at com.android.dx.command.dexer.Main.processAllFiles(Main.java:183) at com.android.dx.command.dexer.Main.run(Main.java:139) at com.android.dx.command.dexer.Main.main(Main.java:120) at com.android.dx.command.Main.main(Main.java:87) /home/aaron/NetBeansProjects/xbmc-remote/nbproject/build-impl.xml:411: exec returned: 3 BUILD FAILED (total time: 1 minute 25 seconds) I can include the build-impl.xml file if you need it, but I don't think that is main issue.

  • Eclipselink factory.createEntityManager() stalls with more than one instance running

    - by Raven
    Hi, with my RCP program I have the problem that I want to have more than one copy running on my PC. The first instance runs very good. If I start the second instance, everything is fine until I want to access the database. Using this code: .. Map properties = new HashMap(); properties.put("javax.persistence.jdbc.driver", dbDriver); properties.put("javax.persistence.jdbc.url", dbUrl); properties.put("javax.persistence.jdbc.user", dbUser); properties.put("javax.persistence.jdbc.password", dbPass); try { factory = Persistence.createEntityManagerFactory( PERSISTENCE_UNIT_NAME, properties); } catch (Exception e) { System.out.println(e); } em=factory.createEntityManager(); // the second instance stops here ... with an persistence.xml of <?xml version="1.0" encoding="UTF-8"?> <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"> <persistence-unit name="default"> <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider> <class>myclasshere</class> <properties> <property name="eclipselink.ddl-generation" value="create-tables" /> <property name="eclipselink.ddl-generation.output-mode" value="database" /> <property name="eclipselink.jdbc.read-connections.min" value="1" /> <property name="eclipselink.jdbc.write-connections.min" value="1" /> <property name="eclipselink.jdbc.batch-writing" value="JDBC" /> <property name="eclipselink.logging.level" value="SEVERE" /> <property name="eclipselink.logging.timestamp" value="false" /> <property name="eclipselink.logging.session" value="false" /> <property name="eclipselink.logging.thread" value="false" /> </properties> </persistence-unit> </persistence> The program stalls / does not continue in the second instance beyond this step: em=factory.createEntityManager(); Debugging the program step by step showed me, that nothing happens at this point. Perhaps the program runs into a timeout. I havent been wainting for more than 1 minute.... Do you have any clues what might cause this stall might?

  • JQuery Tooltip Plugin from Jorn

    - by Jeff Ancel
    I am thinking someone may have run across this one, but not sure. From a high level, I am trying to roll over a input [type=text] and display a tool tip (with the contained value) using the plugin available at http://bassitance.de. I have to use titles and classes for validation on the specific elements, so I put a blank div to hold the input [type=text] value for the roll over. Issue: It won't hold the value of 2 text boxes at once. Once I put a value in the box on the right, the tooltip on the left goes away. Same thing if I switch it aroun. I can't keep a tooltip on more than one element. Here is the code (Note: You will have to download the plugins in the source as I am not sure where the live versions are if there are any). <link rel="stylesheet" href="/scripts/jquery-tooltip/jquery.tooltip.css" /> <script type="text/javascript" src="/scripts/jquery-1.3.2.min.js"></script> <script type="text/javascript" src="/scripts/jquery-tooltip/jquery.tooltip.min.js"></script> <script type="text/javascript"> $(function(){ $("input").change(function(){ var newTitle = $(this).val(); $(this).parent().attr("title",newTitle); // re-init tool tip reload(); }); // Init tooltip reload(); }); reload = function(){ $("div").tooltip(); } </script> <body> <table border="1px solid black"> <tr> <td title="hello"> <div> <input type="text" value=""/> </div> </td> <td> <div> <input type="text" value=""/> </div> </td> </tr> </table> <div id="debug"></div> </body> </html>

  • Data validation best practices: how can I better construct user feedback?

    - by Cory Larson
    Data validation, whether it be domain object, form, or any other type of input validation, could theoretically be part of any development effort, no matter its size or complexity. I sometimes find myself writing informational or error messages that might seem harsh or demanding to unsuspecting users, and frankly I feel like there must be a better way to describe the validation problem to the user. I know that this topic is subjective and argumentative. StackOverflow might not be the proper channel for diving into this subject, but like I've mentioned, we all run into this at some point or another. There are so many StackExchange sites now; if there is a better one, feel free to share! Basically, I'm looking for good resources on data validation and user feedback that results from it at a theoretical level. Topics and questions I'm interested in are: Content Should I be describing what the user did correctly or incorrectly, or simply what was expected? How much detail can the user read before they get annoyed? (e.g. Is "Username cannot exceed 20 characters." enough, or should it be described more fully, such as "The username cannot be empty, and must be at least 6 characters but cannot exceed 30 characters."?) Grammar How do I decide between phrases like "must not," "may not," or "cannot"? Delivery This can depend on the project, but how should the information be delivered to the user? Should it be obtrusive (e.g. JavaScript alerts) or friendly? Should they be displayed prominently? Immediately (i.e. without confirmation steps, etc.)? Logging Do you bother logging validation errors? Internationalization Some cultures prefer or better understand directness over subtlety and vice-versa (e.g. "Don't do that!" vs. "Please check what you've done."). How do I cater to the majority of users? I may edit this list as I think more about the topic, but I'm genuinely interest in proper user feedback techniques. I'm looking for things like research results, poll results, etc. I've developed and refined my own techniques over the years that users seem to be okay with, but I work in an environment where the users prefer to adapt to what you give them over speaking up about things they don't like. I'm interested in hearing your experiences in addition to any resources to which you may be able to point me.

  • Nested Sortable JQuery list doesn't work in IE while it does in FF

    - by Ben Fransen
    Hello everybody, While I'm using this site quite often as a resource for jQuery related problems I can't seem to find an answer this time. So here is my first post. During daytime at work I'm developing an informationsystem for generating MS Word documents. One of the modules I'm developing is for defining a default chapterselection for the table of contents and selecting texts by the given chapters. A user can submit new chapters and if necessary, add them as childchapter to a parent, flag them as 'adopt in TOC' and link a default text (from another module) to the chapter. My chapterlist is retreived recursively from a MySQL table and could look something like this: <ul class="sortableChapterlist"> <li>1</li> <li>2 <ul class="sortableChapterlist"> <li>2.1</li> <li>2.2</li> <li>2.3 <ul class="sortableChapterlist"> <li>2.3.1</li> <li>2.3.2</li> </ul> </li> </ul> </li> </ul> In FireFox the code works like a charm but IE (7) doesn't seem to like it that much. I'm only able to correctly drag arround the mainchapters. When attempting to drag a subchapter, no matter it's level, the correspondending mainchapter lifts up with some child, never all. This is the jQuery code I'm using to accomplish the task: $(function(){ $(".sortableChapterlist").sortable({ opacity: 0.7, helper: 'clone', cursor: 'move' }); $(".sortableChapterlist").selectable(); $(".sortableChapterlist").disableSelection(); }); Does anybody have some ideas about this? I'm guessing IE kinda falls over the multiple class reference "chapter_list" in combination with jQuery trying to handle the draggable/sortable. Kinds regards from Holland, Ben Fransen

  • log4net not logging with a mixture of .net 1.1 and .net 3.5

    - by Jim P
    Hi All, I have an iis server on a windows 2003 production machine that will not log using log4net in the .net3.5 web application. Log4net works fine in the 1.1 apps using log4net version 1.2.9.0 and but not the 3.5 web app. The logging works fine in a development and staging environment but not in production. It does not error and I receive no events logged in the event viewer and don't know where to look next. I have tried both versions of log4net (1.2.9.0 and 1.2.10.0) and both work in development and staging but not in production. For testing purposes I have created just a single page application that just echos back the time when the page is hit and also is supposed to log to my logfile using log4net. Here is my web.config file: <configSections> <!-- LOG4NET Configuration --> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" requirePermission="false" /> </configSections> <log4net debug="true"> <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender"> <param name="File" value="D:\DIF\Logs\TestApp\TestApp_"/> <param name="AppendToFile" value="true"/> <param name="RollingStyle" value="Date"/> <param name="DatePattern" value="yyyyMMdd\.\l\o\g"/> <param name="StaticLogFileName" value="false"/> <layout type="log4net.Layout.PatternLayout"> <param name="ConversionPattern" value="%date{HH:mm:ss} %C::%M [%-5level] - %message%newline"/> </layout> </appender> <root> <level value="ALL"/> <appender-ref ref="RollingFileAppender"/> </root> </log4net> Here is my log4net initialization: // Logging for the application private static ILog mlog = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType); protected void Application_Start(object sender, EventArgs e) { try { // Start the configuration of the Logging XmlConfigurator.Configure(); mlog.Info("Started logging for the TestApp Application."); } catch (Exception ex) { throw; } } Any help would be greatly appreciated.

  • WSIT, Maven, and wsimport -- Can They Work Together?

    - by rtperson
    Hi all, I'm working on a small-ish multi-module project in Maven. We've separated the UI from the database layer using Web Services, and thanks to the jaxws-maven-plugin, the creation of the WSDL and WS client are more or less handled for us. (The plugin is essentially a wrapper around wsgen and wsimport.) So far so good. The problem comes when I try to layer WSIT security into the picture. NetBeans allows me to generate the security metadata easily, but wsimport seems completely incapable of dealing with anything beyond a Basic-auth level of security. Here's our current, insecure way of calling wsimport during a Maven build: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>jaxws-maven-plugin</artifactId> <version>1.10</version> <executions> <execution> <goals> <goal>wsimport</goal> </goals> <configuration> <wsdlUrls> <wsdlUrl>${basedir}/../WebService/target/jaxws/wsgen/wsdl/WebService.wsdl</wsdlUrl> </wsdlUrls> <packageName>com.yourcompany.appname.ws.client</packageName> <sourceDestDir>${basedir}/src/main/java</sourceDestDir> <destDir>${basedir}/target/jaxws</destDir> </configuration> </execution> </executions> </plugin> I have tried playing around with xauthFile, xadditionalHeaders, passing javax.xml.ws.security.auth.username and password through args. I have also tried using wsimport from the command line to point to the Tomcat-generated WSDL, which has the additional security info. Nothing, however, seems to change the composition of the wsimport-generated files at all. So I guess my question here is, to get a WSIT-compliant client, am I stuck abandoning Maven and the jaxws plugin altogether? Is there a way to get a WSIT client to auto-generate? Or will I need to generate the client by hand? Let me know if you need any additional info beyond what I've written here. I'm deploying to Tomcat, although that doesn't seem to be an issue, as Maven seems happy to pull Metro into the deployed WAR file. Thanks in advance!

  • Difficulty getting Saxon into XQuery mode instead of XSLT

    I'm having difficulty getting XQuery to work. I downloaded Saxon-HE 9.2. It seems to only want to work with XSLT. When I type: java -jar saxon9he.jar I get back usage information for XSLT.

  • Connecting to a WSE 3.0 Web Service From a WCF Client

    - by Dave
    I'm having difficulty connecting to a 3rd party WSE 3.0 web service from a WCF client. I have implemented the custom binding class as indicated in this KB article: http://msdn.microsoft.com/en-us/library/ms734745.aspx The problem seems to have to do with the security assertion used by the web service - UsernameOverTransport. When I attempt to call a method, I get the following exception: System.InvalidOperationException: The 'WseHttpBinding'.'[namespace]' binding for the 'MyWebServiceSoap'.'[namespace]' contract is configured with an authentication mode that requires transport level integrity and confidentiality. However the transport cannot provide integrity and confidentiality.. It is expecting a username, password, and CN number. In the example code supplied to us by the vendor, these credentials are bundled in a Microsoft.Web.Services3.Security.Tokens.UsernameToken. Here's the example supplied by the vendor: MyWebServiceWse proxy = new MyWebServiceWse(); UsernameToken token = new UsernameToken("Username", "password", PasswordOption.SendPlainText); token.Id = "<supplied CN Number>"; proxy.SetClientCredential(token); proxy.SetPolicy(new Policy(new UsernameOverTransportAssertion(), new RequireActionHeaderAssertion())); MyObject mo = proxy.MyMethod(); This works fine from a 2.0 app w/ WSE 3.0 installed. Here is a snippet of the code from my WCF client: EndpointAddress address = new EndpointAddress(new Uri("<web service uri here>")); WseHttpBinding binding = new WseHttpBinding(); // This is the custom binding I created per the MS KB article binding.SecurityAssertion = WseSecurityAssertion.UsernameOverTransport; binding.EstablishSecurityContext = false; // Not sure about the value of either of these next two binding.RequireDerivedKeys = true; binding.MessageProtectionOrder = MessageProtectionOrder.SignBeforeEncrypt; MembershipServiceSoapClient proxy = new MembershipServiceSoapClient(binding, address); // This is where I believe the problem lies – I can’t seem to properly setup the security credentials the web service is expecting proxy.ClientCredentials.UserName.UserName = "username"; proxy.ClientCredentials.UserName.Password = "pwd"; // How do I supply the CN number? MyObject mo = proxy.MyMethod(); // this throws the exception I've scoured the web looking for an answer to this question. Some sources get me close (like the MS KB article), but I can't seem to get over the hump. Can someone help me out?

  • Finding minimum cut-sets between bounded subgraphs

    - by Tore
    If a game map is partitioned into subgraphs, how to minimize edges between subgraphs? I have a problem, Im trying to make A* searches through a grid based game like pacman or sokoban, but i need to find "enclosures". What do i mean by enclosures? subgraphs with as few cut edges as possible given a maximum size and minimum size for number of vertices for each subgraph that act as a soft constraints. Alternatively you could say i am looking to find bridges between subgraphs, but its generally the same problem. Given a game that looks like this, what i want to do is find enclosures so that i can properly find entrances to them and thus get a good heuristic for reaching vertices inside these enclosures. So what i want is to find these colored regions on any given map. My Motivation The reason for me bothering to do this and not just staying content with the performance of a simple manhattan distance heuristic is that an enclosure heuristic can give more optimal results and i would not have to actually do the A* to get some proper distance calculations and also for later adding competitive blocking of opponents within these enclosures when playing sokoban type games. Also the enclosure heuristic can be used for a minimax approach to finding goal vertices more properly. A possible solution to the problem is the Kernighan-Lin algorithm: function Kernighan-Lin(G(V,E)): determine a balanced initial partition of the nodes into sets A and B do A1 := A; B1 := B compute D values for all a in A1 and b in B1 for (i := 1 to |V|/2) find a[i] from A1 and b[i] from B1, such that g[i] = D[a[i]] + D[b[i]] - 2*c[a][b] is maximal move a[i] to B1 and b[i] to A1 remove a[i] and b[i] from further consideration in this pass update D values for the elements of A1 = A1 / a[i] and B1 = B1 / b[i] end for find k which maximizes g_max, the sum of g[1],...,g[k] if (g_max > 0) then Exchange a[1],a[2],...,a[k] with b[1],b[2],...,b[k] until (g_max <= 0) return G(V,E) My problem with this algorithm is its runtime at O(n^2 * lg(n)), i am thinking of limiting the nodes in A1 and B1 to the border of each subgraph to reduce the amount of work done. I also dont understand the c[a][b] cost in the algorithm, if a and b do not have an edge between them is the cost assumed to be 0 or infinity, or should i create an edge based on some heuristic. Do you know what c[a][b] is supposed to be when there is no edge between a and b? Do you think my problem is suitable to use a multi level problem? Why or why not? Do you have a good idea for how to reduce the work done with the kernighan-lin algorithm for my problem?

  • EJB3 Transaction Propogation

    - by Matt S.
    I have a stateless bean something like: @Stateless public class MyStatelessBean implements MyStatelessLocal, MyStatelessRemote { @PersistenceContext(unitName="myPC") private EntityManager mgr; @TransationAttribute(TransactionAttributeType.SUPPORTED) public void processObjects(List<Object> objs) { // this method just processes the data; no need for a transaction for(Object obj : objs) { this.process(obj); } } @TransationAttribute(TransactionAttributeType.REQUIRES_NEW) public void process(Object obj) { // do some work with obj that must be in the scope of a transaction this.mgr.merge(obj); // ... this.mgr.merge(obj); // ... this.mgr.flush(); } } The typically usage then is the client would call processObjects(...), which doesn't actually interact with the entity manager. It does what it needs to do and calls process(...) individually for each object to process. The duration of process(...) is relatively short, but processObjects(...) could take a very long time to run through everything. Therefore I don't want it to maintain an open transaction. I do need the individual process(...) operations to operate within their own transaction. This should be a new transaction for every call. Lastly I'd like to keep the option open for the client to call process(...) directly. I've tried a number of different transaction types: never, not supported, supported (on processObjects) and required, requires new (on process) but I get TransactionRequiredException every time merge() is called. I've been able to make it work by splitting up the methods into two different beans: @Stateless @TransationAttribute(TransactionAttributeType.NOT_SUPPORTED) public class MyStatelessBean1 implements MyStatelessLocal1, MyStatelessRemote1 { @EJB private MyStatelessBean2 myBean2; public void processObjects(List<Object> objs) { // this method just processes the data; no need for a transaction for(Object obj : objs) { this.myBean2.process(obj); } } } @Stateless public class MyStatelessBean2 implements MyStatelessLocal2, MyStatelessRemote2 { @PersistenceContext(unitName="myPC") private EntityManager mgr; @TransationAttribute(TransactionAttributeType.REQUIRES_NEW) public void process(Object obj) { // do some work with obj that must be in the scope of a transaction this.mgr.merge(obj); // ... this.mgr.merge(obj); // ... this.mgr.flush(); } } but I'm still curious if it's possible to accomplish this in one class. It looks to me like the transaction manager only operates at the bean level, even when individual methods are given more specific annotations. So if I mark one method in a way to prevent the transaction from starting calling other methods within that same instance will also not create a transaction, no matter how they're marked? I'm using JBoss Application Server 4.2.1.GA, but non-specific answers are welcome / preferred.

  • progressIndicator does not update till about 10 seconds after awakeFromNib occures

    - by theprojectabot
    I have been trying to get this one section of my UI to immediatly up date when the document loads into view. The awakeFromNib fires the pasted code and then starts a timer to repeat every 10 seconds... I load a default storage location: ~/Movies... which shows up immediately.. yet the network location that is saved in the document that gets pulled from the XML only seems to show up after the second firing of the - (void)updateDiskSpaceDisplay timer. I have set breakpoints and know that the ivars that contain the values that are being put into the *fileSystemAttributes is the network location right when the awakeFromNib occurs... Im confused why it magically appears after the second time firing instead of immediately displaying the write values. - (void)updateDiskSpaceDisplay { // Obtain information about the file system used on the selected storage path. NSError *error = NULL; NSDictionary *fileSystemAttributes = [[NSFileManager defaultManager] attributesOfFileSystemForPath:[[[self settings] containerSettings] storagePath] error:&error]; if( !fileSystemAttributes ) return; // Get the byte capacity of the drive. long long byteCapacity = [[fileSystemAttributes objectForKey:NSFileSystemSize] unsignedLongLongValue]; // Get the number of free bytes. long long freeBytes = [[fileSystemAttributes objectForKey:NSFileSystemFreeSize] unsignedLongLongValue]; // Update the level indicator, and the text fields to show the current information. [totalDiskSpaceField setStringValue:[self formattedStringFromByteCount:byteCapacity]]; [totalDiskSpaceField setNeedsDisplay:YES]; [usedDiskSpaceField setStringValue:[self formattedStringFromByteCount:(byteCapacity - freeBytes)]]; [usedDiskSpaceField setNeedsDisplay:YES]; [diskSpaceIndicator setMaxValue:100]; [diskSpaceIndicator setIntValue:(((float) (byteCapacity - freeBytes) / (float) byteCapacity) * 100.0)]; [diskSpaceIndicator display:YES]; } thoughts? my awakeFromNib: - (void)awakeFromNib { [documentWindow setAcceptsMouseMovedEvents:YES]; [documentWindow setDelegate:self]; [self updateSettingsDisplay]; [self updateDiskSpaceDisplay]; [self setDiskSpaceUpdateTimer:[NSTimer scheduledTimerWithTimeInterval:10.0 target:self selector:@selector(updateDiskSpaceDisplay) userInfo:NULL repeats:YES]]; [self setUpClipInfoTabButtons]; [self performSelector:@selector(setupEngineController) withObject:NULL afterDelay:0.1]; }

  • iPhone app with tab bar and navigation bar as peers

    - by Mac
    I'm trying to write an application that uses a navigation bar and tab bar in what (I'm gathering) is an unusual manner. Basically, I've got several "pages" ("home", "settings", etc) that each have their own tab. I'd also like to have it so that the "home" page is the root view of the navigation bar, and the other pages are the second-level views of the navigation bar. That is, I should be able to navigate to any page by clicking the appropriate tab bar item, and should be able to navigate to the home page from any other page by clicking the navigation bar's back button. Currently, I have a UINavigationBar (through a UINavigationController) and a UITabBar (through a UITabController) as children of a UIView. The various pages' view controllers are set as the tab controller's viewControllers property, and the home page's controller is also set as the navigation controller's root view. Each page view's tag is set to its index in the tab control. I have the following logic in the tab controller's didSelectViewController delegate method: - (void) tabBarController:(UITabBarController*) tabBarController didSelectViewController:(UIViewController*) viewController { if ([navController.viewControllers count] > 1) [navController popViewControllerAnimated:NO]; [navController pushViewController:viewController animated:YES]; } Also, in the navigation controller's didShowViewController delegate method, I have the following code: - (void) navigationController:(UINavigationController *) navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated { tabController.selectedIndex = viewController.view.tag; } The problem that's occurring is that when I run this, the navigation bar, tab bar and home page all display ok, but the tab bar will not respond to input - I cannot select a different tab. I gather it's more usual to have the tab bar as the child of the navigation control, or vice versa. This doesn't seem to fit my approach, because I don't want to have to individually create the subordinate control each time a change occurs in the parent control - eg: recreate tab bar each time the navigation bar changes. Does anyone have suggestions as to what's wrong and how to fix it? I'm probably missing something obvious, but whatever it is I can't seem to find it. Thanks! EDIT: I'm guessing it has something to do with both controller's trying to have ownership of the page controller, but I can't for the life of me figure out a way around it.

  • How to do role-based access control for a franchise business?

    - by FreshCode
    I'm building the 2nd iteration of a web-based CRM+CMS for a franchise service business in ASP.NET MVC 2. I need to control access to each franchise's services based on the roles a user is assigned for that franchise. 4 examples: Receptionist should be able to book service jobs in for her "Atlantic Seaboard" franchise, but not do any reporting. Technician should be able to alter service jobs, but not modify invoices. Managers should be able to apply discount to invoices for jobs within their stores. Owner should be able to pull reports for any franchises he owns. Where should franchise-level access control fit in between the Data - Services - Web layer? If it belongs in my Controllers, how should I best implement it? Partial Schema Roles class int ID { get; set; } // primary key for Role string Name { get; set; } Partial Franchises class short ID { get; set; } // primary key for Franchise string Slug { get; set; } // unique key for URL access, eg /{franchise}/{job} string Name { get; set; } UserRoles mapping short FranchiseID; // related to franchises table Guid UserID; // related to Users table int RoleID; // related to Roles table DateTime ValidFrom; DateTime ValidUntil; Background I built the previous CRM in classic ASP and it runs the business well, but it's time for an upgrade to speed up workflow and leave less room for error. For the sake of proper testing and better separation between data and presentation, I decided to implement the repository pattern as seen in Rob Conery's MVC Storefront series. Controller Implementation Access Control with [Authorize] attribute If there was just one franchise involved, I could simply limit access to a controller action like so: [Authorize(Roles="Receptionist, Technician, Manager, Owner")] public ActionResult CreateJob(Job job) { ... } And since franchises don't just pop up over night, perhaps this is a strong case to use the new Areas feature in ASP.NET MVC 2? Or would this lead to duplicate Views? Controllers, URL Routing & Areas Assuming Areas aren't used, what would be the best way to determine which franchise's data is being accessed? I thought of this: {franchise}/{controller}/{action}/{id} or is it better to determine a job's franchise in a Details(...) action and limit a user's action with [Authorize]: {job}/{id}/{action}/{subaction} {invoice}/{id}/{action}/{subaction} which makes more sense if any user could potentially have access to more than one franchise without cluttering the URL with a {franchise} parameter. Any input is appreciated.

  • Asp.net MVC and MOSS 2010 integration

    - by Robert Koritnik
    Just a sidenote: I'm not sure whether I should post this to serverfault as well, because some MOSS admin may have some info for me as well? A bit of explanation first (without Asp.net MVC) Is it possible to integrate the two? Is it possible to write an application that would share at least credential information with MOSS? I have to write a MOSS application that has to do with these technologies: MOSS 2010 Personal client certificates authentication (most probably on USB keys) Active Directory Federation Services Separate SQL DB that would serve application specific data (separate as not being part of MOSS DB) How should it work? Users should authenticate using personal certificates into MOSS 2010 There would be a certain part of MOSS that would be related to my custom application This application should only authorize certain users via AD FS - I guess these users should have a certain security claim attached to them This application should manage users (that have access to this app) with additional (app specific) security claims related to this application (as additional application level authorization rights for individual application parts) This application should use custom SQL 2008 DB heavily with its own data This application should have the possibility to integrate with external systems as well (Exchange for instance to inject calendar entries, ERP systems etc) This application should be able to export its data (from its DB) to files. I don't know if it's possible, but it would be nice if the app could add these files to MOSS and attach authorization info to them so only users with sufficient rights would be able to view/open these files. Why Asp.net MVC then? I'm very well versed in Asp.net MVC (also with the latest version) and I haven't done anything on Sharepoint since version 2003 (which doesn't do me no good or prepare me for the latest version in any way shape or form). This project will most probably be a death march project so I would rather write my application as a UI rich Asp.net MVC application and somehow integrate it into MOSS. But not only via a link, because I would like to at least share credentials, so users wouldn't need to re-login when accessing my app. Using Asp.net MVC I would at least have the possibility to finish on time or be less death marching. Is this at all possible? Questions Is it possible to integrate Asp.net MVC into MOSS as described above? If integration is not possible, would it be possible to create a completely MOSS based application that would work as described? Which parts of MOSS 2010 should I use to accomplish what I need?

  • Drawing performance with CGImageCreateWithJPEGDataProvider?

    - by Rnegi
    I've actually curious about this for the iPhone. I am getting an MJPEG stream from a server and trying to render it natively on the iphone (without the use of safari class). Reasons for this is because the safari class while CAN render MJPEG natively, does not do so at the framerate I would like. So I tried drawing it natively, but I've come up with performance issues, namely a syncing issue between what I'm getting from the server and what I am able to draw onto the screen of the phone. (There should be a little lag, but the drift gets really bad, which is what I want to avoid). So I have a connection set up to my server and I do get the JPEGS. It's just data I insert into a NSMutableArray buffer CFMutableDataRef _t_data_ref = (CFMutableDataRef)[_buffer_array objectAtIndex:0]; //CGDataProviderRef imgDataProvider = CGDataProviderCreateWithCFData (_cf_buffer_data); CGDataProviderRef imgDataProvider = CGDataProviderCreateWithCFData(_t_data_ref); CGImageRef image = CGImageCreateWithJPEGDataProvider(imgDataProvider, NULL, true, kCGRenderingIntentDefault); CGImageRef imgRef = image; CGContextDrawImage(context, CGRectMake(0, 17, 380, 285), imgRef); CGImageRelease(image); CGDataProviderRelease(imgDataProvider); please note this is the gist of my code, but it should summarize what I am trying to accomplish with regards to drawing. Also in order to get the framerate in sync, I had to detach a separate thread that sleeps X seconds and calls [self setNeedsDisplay]. NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; // Top-level pool while(1) { //[NSThread sleepForTimeInterval:TIMER_REFRESH_VALUE]; //sleep(unsigned int ); usleep(MICRO_REFRESH_VALUE); if ([_buffer_array count] > 10) { //NSLog(@"stuff %d", [_buffer_array count]); //[self setNeedsDisplay]; [self performSelectorOnMainThread:@selector(setNeedsDisplay) withObject:nil waitUntilDone:NO]; } } [pool release]; // Release the objects in the pool. My buffer of jpeg data actually fills up quite quick, but I can't seem to actually consume what i'm getting at the same rate, actually much slower. Are there any documents that can describe what kind of performance tuning I can do to make it go faster when rendering the JPEG to the screen? Or am I kind of stuck here? Thanks!

  • Why does Visual Studio 2010 throw this error with Boost 1.42.0?
