[jboss-user] [JBoss jBPM] - java.sql.SQLException: You cannot commit during a managed tr

[trouby]

Hey,

I have created a very simple seam component that injects the jbpmContext and uses it to create the schema, this is the code:



  | @name("workflowManager")
  | public class WorkflowManager {
  | 
  | @In
  | private JbpmContext jbpmContext;
  | 
  | 
  | public void createJbpmSchema() {
  |   jbpmContext.getJbpmConfiguration().createSchema()
  | }
  | }
  | 


When invoked, I get the following exception:

  | 21:13:32,867 ERROR [SchemaExport] schema export unsuccessful
  | java.sql.SQLException: You cannot commit during a managed transaction!
  |         at org.jboss.resource.adapter.jdbc.BaseWrapperManagedConnection.jdbcCommit(BaseWrapperManagedConnection.java:581)
  |         at org.jboss.resource.adapter.jdbc.WrappedConnection.commit(WrappedConnection.java:482)
  |         at org.hibernate.tool.hbm2ddl.ManagedProviderConnectionHelper.prepare(ManagedProviderConnectionHelper.java:30)
  |         at org.hibernate.tool.hbm2ddl.SchemaExport.execute(SchemaExport.java:180)
  |         at org.hibernate.tool.hbm2ddl.SchemaExport.create(SchemaExport.java:133)
  | ...
  | 


I looked at the source code of  the createSchema method,
Seems like it's just invoking jbpmContext.close(); at the end.


My JBPM/hibernate configured in the right way not to start/close a transaction it didn't start.



What is the reason of the exception?


Thanks,


Asaf.
