Nils Preusker, Joram Barrez and I have uploaded some demo’s on jBPM4. If you like to start fast and use demo’s which integrates different technologies, this is a good place to start.
You can find the demo’s at the jbpm svn.
Regards!

Great example guys. Thank you so much!!
I am running into a problem and I can’t figure out what to do. Here’s the interesting part of the code:
org.hibernate.dialect.PostgreSQLDialect
false
org.hibernate.cache.EhCacheProvider
true
true
org.hibernate.transaction.JDBCTransactionFactory
thread
classpath:hibernate.cfg.xml
classpath:jbpm.execution.hbm.xml
classpath:jbpm.repository.hbm.xml
classpath:jbpm.task.hbm.xml
classpath:jbpm.history.hbm.xml
When I start it up it works fine. However, hibernate throws an error:

Any ideas why it’s not getting my transactionManager? Your setup and mine are almost identical.
My spring beans didn’t display properly
HI, i would like to ask if I can create a state inside a process which called as sub-process? thanks
Andre:
I have a question @ http://www.inze.be/andries/?p=122 that you could answer for me. But basically, I am running into many problems when building your jBPM4 example from source, in that the maven dependencies are broken or missing, especially the 4.0.0-SNAPSHOT ones. Appreciate in advance your answers.
