=== Problem description =========================
Hi,
the errors above appears after starting the process via the jBPM console.
Is my process definition wrong? I would like to check if a service is running and proceed afterwards.
The problems seems to be located at the timer.
Thanks for your help. I'm new to jBPM and open for any solutions.
Greetings,
Jonas

[jBPM Users] - Re: jBPM-4.2 Remote API problem?
by markroy
My jbpm.cfg.xml under JBoss is:
| <?xml version="1.0" encoding="UTF-8"?>
|
| <jbpm-configuration jndi-name="java:/ProcessEngine">
|
| <import resource="jbpm.default.cfg.xml" />
| <import resource="jbpm.businesscalendar.cfg.xml" />
| <import resource="jbpm.tx.jta.cfg.xml" />
| <import resource="jbpm.jpdl.cfg.xml" />
| <import resource="jbpm.identity.cfg.xml" />
| <import resource="jbpm.jobexecutor.cfg.xml" />
| <import resource="jbpm.console.cfg.xml" />
|
| </jbpm-configuration>
|
which imports jbpm.default.cfg.xml, but I explictly added
| <process-engine-context>
| <object class="org.jbpm.pvm.internal.id.DatabaseIdComposer" init="eager" />
| </process-engine-context>
|
I see this in server.log
| DEBUG [org.jbpm.jboss.internal.JbpmService] (main) JbpmService starting...
| DEBUG [org.jbpm.pvm.internal.cfg.ProcessEngineImpl] (main) jndi name java:/ProcessEngine is not bound
| DEBUG [org.jbpm.pvm.internal.wire.WireContext] (main) eagerly initializing org.jbpm.pvm.internal.id.DatabaseIdComposer
| DEBUG [org.jbpm.pvm.internal.wire.WireContext] (main) eagerly initializing org.jbpm.pvm.internal.jobexecutor.JobExecutor
| DEBUG [org.jbpm.pvm.internal.cfg.ProcessEngineImpl] (main) publishing jBPM ProcessEngine in jndi at java:/ProcessEngine
|
so, that seems to be loaded, but I still get the same problem.
It doesn't make sense to me that the database should be checked (checkDb()) locally (at the 'client side'), but I added DatabaseIdComposer to that jbpm.cfg.xml anyway. Same problem. The client side of the remote API doesn't necessarily have a connection to the database. Shouldn't checkDb() be executed at the remote (JBoss) end?

[jBPM Users] - jBPM Customization with EMF and DSL
by xspyro
Hi,
I'm wondering how easy would it be to replace processdefinition.xml with some custom DSL.
What I would like to do is to benefit from all nice features jBPM provides but instead of using xml as process definition use DSL (Domain Specific Language) to instrument PVM. I know that PVM is exactly about that (or maybe not) but the picture is kind of blurred when it comes to highlighting differences between PVM and jPDL.
Next interesting question would be: How easy or difficult would be to replace storage, from RDBMS based to key-value store for example? I've been going through source code back in version 3 and it didn't looked that simple. Is there any kind of abstraction in place which would enable simple storage replacement?
Regards,
Jakub
