The problems you mentioned should be already solved. Some times stale state exception can be printed out but invocation is done properly, thanks to retry mechanism that is built in jBPM. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/553183#553183] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [Beginner's Corner] - Upgrading JBoss 4.0 to 5.1 - application won't connect

I did check that. I also tried recompiling all the server and client code with the new jbossall-client.jar. I'm starting the jboss server with just the run command, but as I said it seems to be running fine - no errors. My client application is a java application that connects to the application server via JNDI lookup. It has no web or browser component at all. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/553175#553175] Start a new discussion in Beginner's Corner at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [jBPM] - How to start/spawn 'n' subprocesses for 'n' users using JBPM-4.3.

To view the discussion, visit: http://community.jboss.org/message/553171#553171 -------------------------------------------------------------- One more thing: the unique constrain problem doesn't depend on the type of the database. I'm sure one can run into it using in-memory db too. It's all about the JBPM4_EXECUTION table definition, i.e. the unique constrain on ID_ field. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/553171#553171] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [jBPM] - How to start/spawn 'n' subprocesses for 'n' users using JBPM-4.3.

by Al Nadein

Al Nadein [http://community.jboss.org/people/matrixpooh] replied to the discussion "How to start/spawn 'n' subprocesses for 'n' users using JBPM-4.3." To view the discussion, visit: http://community.jboss.org/message/553170#553170 -------------------------------------------------------------- Hi Felix, A unique constrain for ID_ on JBMP4_EXECUTION is there to ensure that there don't exist more than 1 process with the same id. Since the only client of this database is the pvm (jbpm process virtual machine) and it's designed having this restriction in mind, there is really no harm to drop the constrain. Being a perfectionist, I still think there should be a code fix, rather than relaxation of the data model constrains. The reason of the error is really a bug. A process is created, then a fork is hit, a child process is created. Both operations are done in memory, nothing is being recorded in a database just yet. Then either a wait state or end of a process is hit. At this moment, a system would try to persist the records: there will be 2 records created - one for the main process, another for the child process. 2 insert statements would be issued, both of them will have "ID_" set to null just because at that moment neither of ID_ values has been calculated yet. This is done with the assumption that there will be a calculation of ID_ values and the updates will be issued immediately in the same transaction. But in this setup, updates have no chance to be issued since the transaction fails to insert the second record due to a duplicate ID_ value, i.e. null. The question is why not to calculate ID_ value upfront and make a single insert instead of insert and then update. I did work with HuieSheng to identify and resolve the bug, but then was pulled into some other things and didn't have a chance to follow up on her patch. In short, my project is in production with my patch. Will try to fetch it for you shortly. Also, wanted to say huge thanks for your process sample: creating an arbitrary number of subprocesses is something I've been trying to do for a while. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/553170#553170] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [JBoss Messaging] - JBOSS Messaging Issue

Peter Johnson [http://community.jboss.org/people/peterj] replied to the discussion "JBOSS Messaging Issue" To view the discussion, visit: http://community.jboss.org/message/553163#553163 -------------------------------------------------------------- All you need to run a messaging client are the JAR files in the client directory (though just now checking with one of my scripts I see that I also include a few JARs from the lib directory). You actually do not need all of them, a tool such as JBoss Tattletale can help you identify the exact files required. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/553163#553163] Start a new discussion in JBoss Messaging at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

I've the same exact problem here and can't seem to figure out how to deploy my process either. I've been googling like mad as well, but only keeps coming back to this thread. I've tried to decipher what you've done here and for the most part am understanding the process you go through. Unfortunately the way my work has deployed jbpm inside of jboss I have a very difficult time understanding where all the locations of dependent files goes. I haven't deployed to the classpath as suggested here but did it work for you? from what I can see here it did not. Thanks for any help. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/553159#553159] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
