[JBoss Tools (users)] - Debugger opens wrong file

by mfinegold

Hello, I am having an issue where the Eclipse Debugger opens the wrong java file when I use the JBoss Tools Eclipse plugin to start JBoss in Debug mode (using eclipse 3.3.1.1 and JBossAS 1.0.0.GA/JBossTools Core 2.0.0.GA) I have 2 Eclipse projects with many of the same java class names and the debugger is opening a file by the same name in the wrong project when I set a breakpoint on a file in the project I'm working on. Is there an Eclipse setting somewhere that says where to find the file that the debugger opens upon hitting a breakpoint? Thx!

[JBoss jBPM] - Problem in deploying processdefinition in a war file

by syedtaj

Hi, I have a war file, which has a servlet that will load on startup to deploy my process definitions like the following - | pdSubProcess = processDefinition.parseXmlResource("AutomationService/processdefinition.xml"); | jbpmContext.deployProcessDefinition(pdSubProcess); I get a java.net.MalformedURLException, cause the class loader is not able to find the process definition, which is strange because it is in the classes folder in WEB-INF automation.war\WEB-INF\classes\AutomationService\processdefinition. I saw the JBOSS code that loads the resource files, it uses the ClassLoader to deploy the resource. I mimicked that code like this ClassLoader automationServiceLoader = AutomationServiceServlet.class.getClassLoader(); | InputStream inputStream = automationServiceLoader.getResourceAsStream("AutomationService/processdefinition.xml"); | pdSuperProcess = ProcessDefinition.parseXmlInputStream(inputStream); | The above code works, but created a new problem. I also wonder why didn't ProcessDefinition.parseXmlResource work because internally it does the same thing, using its own class - ClassLoaderUtil.class.getClassLoader() I am stumped. Now the second problem, after making the above work and once all the process definitions are deployed, the action classes that they refer to from the process definitions are not visible to class loader, and I get a ClassNotFoundException. I tried making a jar file and placing it in the WEB-INF\lib folder as well, with no success. I guess thats because I am using a different class loader to load the process definitions, the class folder in WEB-INF or the lib folders are not visible to it. Thus how do I actually make this work, how do I deploy the processdefinitions along with its related class files. Any help would be appreciated. Stuck from some time on this one.

[Beginners Corner] - Re: how to create new user for durable topic subscriber lik

by PeterJ

I am not sure which JMS example you are using. The only use of the user/password of john/needle that I could find was for some of the JMS tests. It appears that for those specific tests, a database login module is used, so the account information is stored in the database. To add new accounts, you would have to update the database. In the JMS source, the files src/etc/server/default/*-persistence-service.xml contains the SQL statements that populate the database with several accounts. You can follow those to create new accounts (and don't forget to add the accounts to the roles!)

[JBoss Messaging] - Re: Clustered server preference

by clebert.suconic＠jboss.com

JCA is to be used internally on the application server. If you have external clients, why do you need the JCA adapter, why you can't just use ClusteredXAConnectionFactory from the client side? anonymous wrote : java.naming.provider.url=jnp://devapp2.qa.cin.int:1100,jnp://devapp1.qa.cin.int:1100 | I'm not sure what this is doing.. please ask it on the JCA forum or look for some documentation. But I believe you messing up with the JCA's load balance and the JBossMessaging load balancing. i.e. you are making up a big mess. The ClsuteredXAConnectionFactory already has a load balancing, and you are putting another load balancing in top of that on this new JCA adapter you're creating. Usually, we prefer to have MDBs aways connecting to the local queue (there is no point on doing a cluster round trip if there is a consumer available on the current node), and then relay on message redistribution if a server is too busy. You should clear up this!

[JBoss jBPM] - Re: jBPM concurrency

by jorgemoralespou_2

I have been throughly reading the forums, reading through the code, and find that although orchestration is a feature??? , as theres is some other people using jBpm to orchestrate services , it doesn't seem to fit the suit. Has anyone use jBpm to do service orchestration, and having solved problems with scalability? Is it possible to modify jBpm, to use a subset of it's functionality to avoid locking? Is it possible to introduce some of PVM`s changes, or is it going to be jBpm 4 based on jPdl over PVM? In such a case, are things like concurrency taken into consideration? Don't break it, now that it seems to be working in PVM. ;-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4144273#4144273 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4144273
