[JBoss Web Services] New message: "Re: java.lang.LinkageError: loader constraint violation:(In JAXW"

by Stuart Smith

User development, A new message was posted in the thread "java.lang.LinkageError: loader constraint violation:(In JAXW": http://community.jboss.org/message/530886#530886 Author : Stuart Smith Profile : http://community.jboss.org/people/stuart_wildcat Message: -------------------------------------------------------------- Although it might have worked for some people, I don't think the best solution to this is to download anything that alters the JBoss installation. I encountered a similar problem and I figure I would share what is likely a better solution as well as an understanding of the original problem... I would bet that most people that have this problem have two to three things in common: - They are using Java SE 6 as the underlying Java SE version - They have tried to generate service code using the standard Eclipse tools or the Sun JAX-WS implementation - They have not altered the Eclipse configuration of their JBoss server to pick up 'endorsed' JARs The problem with this is that many XML and web service APIs that were not in Java SE 5 (1.5) were added to Java SE 6. Java EE 5 however, only requires Java SE 5 or above and since you pick your own JRE to run under JBoss some people use Java SE 5 and others Java SE 6. The problem is that the addition of the XML and web service APIs in Java SE 6 causes somewhat of a conflict in JBoss. The "best" way to get around this is to use the "JDK6" version of JBoss download if you are using a Java SE 6 environment. If you look at the differences between this and the "regular" (Java SE 5) download the main difference is the presence of the '<JBOSS>/lib/endorsed' folder. The startup command for the JBoss JDK 6 version basically says "use the JARs in the 'endorsed' folder because I want to use those instead of the ones provided by the Java SE 6 runtime. That wouldn't really matter except that when you generate code using the standard Eclipse tools or the Sun JAX-WS implementation it will use the JARs from the Java SE 6 environment and create the conflict. You also might end up with extra JARs from things like Axis in your WEB-INF/lib folder which will throw things off. If you use the tools provided with JBoss to generate code you should pick up the right versions of JARs and not have a problem. http://community.jboss.org/docs/DOC-13544 The third thing you may have to do, only if you are running JBoss from the Eclipse 'Servers' view, is to alter the way Eclipse starts JBoss to also pick up the 'endorsed' directory. When you run JBoss from the command line it picks up the 'endorsed' directory without any options needed but Eclipse starts JBoss in a slightly different way and ignores the 'endorsed' JARs by default. To alter an Eclipse JBoss server definition to pick up the 'endorsed' directory when running using Java SE 6: - Right click the server definition in the 'Servers' view and select 'Open' - In the 'Overview' information look for a link that will open the "launch configuration" - Select the 'Arguments' tab in the dialog that opens to edit the configuration - Add the following argument making sure to have a space before the dash at the start of the argument and substitute the actual directory you extracted JBoss to for <JBOSS> below -Djava.endorsed.dirs="<JBOSS>\lib\endorsed" - Close the launch configuration dialog and the server configuration page. All of these things should help avoid these issues in JBoss without needing to resort to patching or replacing the JBossWS implementation shipped with JBoss (unless you need to for other reasons). I guess the good thing though is that all of these errors are very specific to JBoss web service applications. If you have a JBoss application that uses Java SE 6 but does not use web services you do not need to go through all of these steps although using the 'JDK 6' download of JBoss is probably best to do at minimum anyway.

I have only available is ProcessInstance ID in my application. I am using the query API to get the ProcessInstance. After that i am invoking 'isEnded()' method to check whether the Process Instance is ended or not. Below is the code which i am using. ++ProcessInstance p = getExecutionService++getExecutionService If (p.isEnded()) { // } It's returning process instance while in execution. Once the execution is ended, the statement is returning null. I have to find out whether the instance is in execution or ended, using ProcessInstanceID. is it the correct way? Please guide me. Thanks! ++ -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/530882#530882

[Performance Tuning] New message: "Periodic Service Delay/Hang"

by Jeffrey Poore

User development, A new message was posted in the thread "Periodic Service Delay/Hang": http://community.jboss.org/message/530880#530880 Author : Jeffrey Poore Profile : http://community.jboss.org/people/jeffrey.poore Message: -------------------------------------------------------------- Mostly I am wondering if anyone else has seen this behavior. We are upgrading our JBoss installation from 4.2.3 to 5.1.0. So far everything has worked great, but we are experiencing periodic service delays - that is, HTTP requests to the server will normally respond in under 1 second, but if the server is left running idle for some time (around 30 minutes or so), a request will hang for several minutes (usually no longer than 4 or 5 minutes). Once the request comes back, HTTP requests come back as normal again. A short while later, we'll see the same delay again. This server is used for our CXF services, and so it really only has a single war on it. Unfortunately, when things get stuck, we get any logging to see if anything is breaking. One interesting side effect is that if the server is stopped while hanging on a request, the request will come back, as if the request had been processed but gets stuck when the server actually goes to send the response. I can provide more details if anyone has any insight. Thanks! -jp -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/530880#530880

[jBPM] New message: "Re: Generate Image from ProcessDefinition"

by henry donnell

User development, A new message was posted in the thread "Generate Image from ProcessDefinition": http://community.jboss.org/message/530879#530879 Author : henry donnell Profile : http://community.jboss.org/people/bestage Message: -------------------------------------------------------------- Like Ronald answered, there is no ready solution to do that. But actually you can achieve what you want... Here is the concept: * for any Process Definition you can get the iImage resource name by calling String *http://docs.jboss.com/jbpm/v4/javadocs/org/jbpm/api/ProcessDefinition.html#getImageResourceName%28%29()...* * now you can use RepositoryService and say *http://docs.jboss.com/jbpm/v4/javadocs/org/jbpm/api/RepositoryService.html#getResourceAsStream%28java.lang.String,%20java.lang.String%29*(java.lang.String deploymentId, java.lang.String resourceName) that will return you the InputStream of the process image * now you can use RepositoryService again and say *http://docs.jboss.com/jbpm/v4/javadocs/org/jbpm/api/RepositoryService.html#getActivityCoordinates%28java.lang.String,%20java.lang.String%29*(java.lang.String processDefinitionId, java.lang.String activityName) * and now presuming you know the name of the current activity in your given process instance (= execution) you can draw that rectangle on the image... How exactly this can be done, can't say for now, but that shouldn't be impossible. By the way this is not my original idea, this was mentioned somewhere on the this forum. Also maybe have a look at the GWT console, the guys have solved the same problem already. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/530879#530879

User development, A new message was posted in the thread "Calling a stateless EJB from a Service POJO": http://community.jboss.org/message/530876#530876 Author : Anu ForWork Profile : http://community.jboss.org/people/anuforwork Message: -------------------------------------------------------------- I have a service POJO (http://www.jboss.org/file-access/default/members/jbossejb3/freezone/docs/...) and I want to access a stateless EJB from the start() or create() method of this Service POJO. If I try to call the stateless EJB from within the Service POJO, I get an NamingNotFound exception. I understand that my stateless EJB will not yet be bound before my Service POJO start method is called. My question is: Is it possible to call a stateless EJB from a service POJO?
