[JBoss-user] [JBoss jBPM] - JMS async continuations
hi,
I had problems running the async stuff with JMS. When I try to run the command
that comes in the message I get a lazy initialization exception because the
hibernate session was closed. I think that it's because the command wasn't
loaded with hibernate, it was serialized with jms. I solved it by creating a
new command instance in my JMS command executor[1]. But it is not safe because
the token might be in another node, maybe the Command interface should include
a new method, e.g. (void execute(JbpmContext context)) that reloads the command
fields and executes the command with the given context, has it any sense?.
And it seems JmsMessageServiceImpl delivers the messages before the process is
saved, it causes the message consumer to try to execute the commands on a
process which is not saved yet. Any idea of how to do a workaround for this?
Any help will be highly appreciated.

[JBoss-user] [JBoss jBPM] - async continuations - JMS factory sends messages before the
Hi, I've got a small problem with the asynchronous continuations. According to the docs "The messages will be sent as part of the GraphSession.saveProcessInstance", my problem is that JMSMessageServiceFactory is sending the messages before the process is saved, is there any config option to make JMSMessageServiceFactory to send the messages only after the process is saved?. I'm using the service deployment model (jbpm.sar) in JBOSS 4.0.3SP1. thanks in advance, edgar JMS factory config | | | | | | | | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3925674#3925674 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3925674 --- This SF.net email is sponsored by: Splunk Inc.

[JBoss-user] [JBoss jBPM] - Re: asyn feature configuration
hi, well, I think I'm a little closer :). It seems it's up to the client to handle the async stuff, either by starting the CommandExecutorThread (e.g. by running the jbpm webapp, or inside a custom app), or by subscribing a MessageListener to the message queue, in case one choses to use org.jbpm.msg.jms.JmsMessageServiceFactoryImpl. I haven't found the JMS counterpart of CommandExecutorThread, is there any MessageListener?, in case I have to implement it, I should do the same CommandExecutorThread stuff plus the JMS handling, right?. Am I in the right direction? any help is highly appreciated br, edgar View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3924706#3924706 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3924706 --- This SF.net email is sponsored by: Splunk Inc.

Hi anonymous wrote : The SendMessagesInterceptor uses the interfaces MessageServiceFactory and MessageService to send messages. This is to make the asynchronous messaging implementation configurable (also in jbpm.cfg.xml). I'm trying to use the new async feature and I'm stucked :(. the queue of messages grow but I don't see any thread consuming them. I'm surely missing a configuration setting to make it work. I don't see any reference to SendMessagesInterceptor in my config gile, how can I configure the interceptor? thanks in advance, edgar View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3924673#3924673 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3924673 --- This SF.net email is sponsored by: Splunk Inc.

Hi rainer the actionhandler that sends the JMS message and the MDB that find the meaning of life seem to be reusable. If I'm not missing something, that's the kind of support that I'd like to see included in JBPM, maybe as a new node type. anonymous wrote : Does this make it any more clear (if you ignore the philosophical distractions)?

hi Rainer anonymous wrote : So my answer to your question is another question: what is the use case for Java concurrency in jBPM? Another use case for the record ;). I'm using jbpm to manage a billing system. The billing process involves not only human interaction but also time consuming queries that I'll run against an oracle 10g cluster. I decided to use JBPM because I thought I could model the concurrent execution of the calculations, unfortunately I was wrong and we are evaluating other products because of this limitation. Other than that I'm very happy with JBPM. br, edgar View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3923433#3923433 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3923433 --- This SF.net email is sponsored by: Splunk Inc.

[JBoss-user] [JBoss jBPM] - Re: unable to delete process instance
hi I tried to dig the cause of this problem, and it seems the deletion of variable instances is not working correctly. My problem is that if I don't remove the variable instances, when I try to remove the process instance I get an exception that complaints about the referential integrity, specifically about the constraint FK_VARINST_TKVARMP, in the table "JBPM_VARIABLEINSTANCE". The curious thing is that when I delete all the variable instances, the process instance can be deleted without problems, but in "JBPM_VARIABLEINSTANCE" remains a variable instance without any value in the "TOKEN_" field. As a workaround I can delete the variable instances in my code, and then delete the process instance itself. I'm a newbie with JBPM, so if I'm missing something important I would really appreciate any help. br, edgar View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3913565#3913565 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3913565 --- This SF.net email is sponsored by: Splunk Inc.
