[Beginners Corner] - Re: JBoss Portal Crash after deploying portlet

by PeterJ

The exception you posted looks like it appeared in your browser. There should be a corresponding exception in the console log, please post that. Portal keeps config info in a database. You might also have to wipe the database to get back to a clean system. In other words, removing the data, temp , log and work dirs is not enough (unless you are using the HSQLDB database, in which case it stores its data in the data directory).

[Installation, Configuration & DEPLOYMENT] - Re: GlassfishConfigureListener NoSuchMethodError

by PeterJ

Looking at the exception again, it appears to be a missing method error, not a missing class. Are you sure you are getting the exact same error message, because if you are one of the Glassfish JAR files is still in your WAR. And check your JSF config files and the web.xml file, and any other config files you have View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4250395#4250395 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4250395

[JBoss Messaging] - Re: Urgent! Clustered-queue on 2 nodes failed

by venkadesan

Hello Glenwood, Can i know what you did to fix the issue? Since we too face similar kind of issue. We have created two queues in cluster and everything works fine JBoss 5.0.0 GA whereas the same code does not work in JBoss 5.1.0 GA where the messages are sent to two queues in round robin (say out of 10 messages, 5 goes to node1 and 5 goes to node 2). When we try to consume, consumer pointing to node1 can consume only 5 from node 1 and nothing from node2. Thanks in advance.

[JBoss jBPM] - Implementing concurrent dynamic tasks in jbpm4

by mwohlf

I try to implement "Pattern 15" in jbpm4 http://www.workflowpatterns.com/patterns/control/multiple_instance/wcp15.php "Multiple Instances without a priori Run-Time Knowledge" try 1) I use a custom implementation of ExternalActivityBehaviour, that basically just waits for signals to spawn off dynamic task instances, the code in signal() to do this looks like this: | DbSession dbSession = Environment.getFromCurrent(DbSession.class); | | // create new task | TaskImpl task = (TaskImpl) dbSession.createTask(); | task.setName(taskname); | task.setNew(true); // no idea what this is but looks good | task.setExecution(execution); | task.setProcessInstance(execution.getProcessInstance()); | task.setSignalling(false); | task.setAssignee("assignor"); | task.setActivityName("complete"); | | // save task | dbSession.save(task); | | // deal with the history table | HistoryEvent.fire(new TaskCreated(task), execution); | this gives me the tasks in the users tasklist and they can be completed, however the problem is the history table, as pointed out in http://www.jboss.org/index.html?module=bb&op=viewtopic&t=160034 there is no way to get the information about the task instance from the taskHistory table, the only useful information would be the activity, but since all these dynamic tasks are created for the same activity this doesn't help much either. try 2) My second approach to implement "Pattern 15" is to use dynamic activities like described in: http://www.jboss.org/index.html?module=bb&op=viewtopic&t=159765 (this isn't exactly the pattern but close enough) the code in this thread implements an event listener which means it can only be invoked on a limited set of workflow events (start, end) when taking transition or entering nodes as far as I understand (someone please correct me if I am missing something here). try 3) So again I tried to implement this in a custom ActivityBehaviour, which can receive random signals with executionService.signalExecutionById(..). I basically use the code from the event listener which dynamically creates a new execution first, then a new Activity and wires them with transitions. The code is in the placeViceMentorTask() method at http://www.jboss.org/index.html?module=bb&op=viewtopic&t=159765 The problem with this approach is: what is the state of the new execution? Execution.STATE_ACTIVE_CONCURRENT doesn't work since it requires a Execution.STATE_INACTIVE_CONCURRENT_ROOT for the parent execution which means I can no longer signal it for more executions. the dynamic created activity and its transitions are not in the process definiton and I can't find any database table for the transitions, now when I reboot the process engine they probably will be lost... so I am running out of ideas and wanted to know if someone is tackling the same problem with more success than I had so far, any ideas are very welcome, the first one with a solution gets a beer from me when he/she is in Stuttgart, Germany View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4250391#4250391 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4250391

[JBoss Portal] - Re: Default encryption scheme for SynchronizingLDAPExtLoginM

by brandonv

We have a similar setup with AD authentication and DB as a backup. I have the DBIdentityLoginModule configured with the options of: <module-option name="hashAlgorithm">MD5</module-option> | <module-option name="hashEncoding">HEX</module-option> I believe these are the defaults for this module.

[JBoss jBPM] - Re: Linking JBPM processes with external entities

by dinosaurus

- We're planning to use JBPM 4.0 but I see no possibility to do mentioned above queries using query API. I see only ProcessInstanceQuery class providing very basic functionality. Or You meant some other API, are You? - If I do queries through Hibernate session I'll be automatically dependent on some internal JBPM classes like: org.jbpm.pvm.internal.model.ExecutionImpl. Is it legal? Which is official JBPM position on that? - Also developer's guide says: "Currently jBPM's persistence is based on hibernate. But in the future we might switch to JPA. That is why we recommend to stick with the API as much as possible as the API will hide you from those changes.

[Beginners Corner] - Re: Authentication Error

by Wolfgang Knauf

Hi, which JBoss version? I assume that you use a custom login module? If yes: please post it, too. In general, you should provide is with much more details about your app. Also, in the "Post reply" window, you should wrap all config and code snippets in "Code"-Blocks (see toolbar button), because this increases readability.

[Installation, Configuration & DEPLOYMENT] - Re: GlassfishConfigureListener NoSuchMethodError

by Jadin

I pulled out the jar files from my maven build on the war app, and it still runs with the same error using the jboss jsf jars. I wonder if it is pulling the jboss jsf files first despite what I have set in the jboss-service.xml file.

[Beginners Corner] - Setting up JBoss Tools in Galileo

by shashank.rudra

Hi Guys I was trying to download the JBoss tools using the way given on this page http://www.jboss.org/tools/download/update.html. I followed all the steps given in there. But some dependency problems came up. After just discarding the ones that were troublesome. I finished the not-all update. First thing I was wondering even if I am trying the location as specified on the site. These problems are coming up. Now after this incomplete installation many projects are not running well. This was as expected. how to do it better way. Please help. Thanks in advance. One of the errors is - After that I tried to create a new Drool Project. But the problem was that particular AJDT is not available. So how to get rid of this thing. Or How to do it a way so as to not get those dependency errors.
