no environment to get org.jbpm.pvm.internal.id.DbidGenerator

Hi,

I have a jBPM environment with Postgres that works perfectly.

I have a jUnit test suite set up to use hsql in memory and can't get that to work, specifically, the jbpm calls bomb out with:

org.jbpm.api.JbpmException: no environment to get org.jbpm.pvm.internal.id.DbidGenerator
    at org.jbpm.pvm.internal.env.EnvironmentImpl.getFromCurrent(EnvironmentImpl.java:203)
    at org.jbpm.pvm.internal.env.EnvironmentImpl.getFromCurrent(EnvironmentImpl.java:196)
    at org.jbpm.pvm.internal.task.ParticipationImpl.<init>(ParticipationImpl.java:52)
    at org.jbpm.pvm.internal.task.TaskImpl.addParticipation(TaskImpl.java:167)
    at org.jbpm.pvm.internal.task.TaskImpl.addCandidateGroup(TaskImpl.java:159)

There is absolutely no documentation in the user or developer guides on how I could change the DbidGenerator, e.g. to make use of the packaged Memory Id Composer. I found some reference to <id-generator> tag, but I no specifics.

What am I missing here? The jbpm.cfb.xml is shared between the app and the test suite, the test suite has its own hibernate config:

<hibernate-configuration>
  <session-factory>
 
     <property name="hibernate.dialect">org.hibernate.dialect.HSQLDialect</property>
     <property name="hibernate.connection.driver_class">org.hsqldb.jdbcDriver</property>
     <property name="hibernate.connection.url">jdbc:hsqldb:mem:.</property>
     <property name="hibernate.connection.username">sa</property>
     <property name="hibernate.connection.password"></property>
     <property name="hibernate.hbm2ddl.auto">create-drop</property>
     <property name="hibernate.format_sql">true</property>
    
     <mapping resource="jbpm.repository.hbm.xml" />
     <mapping resource="jbpm.execution.hbm.xml" />
     <mapping resource="jbpm.history.hbm.xml" />
     <mapping resource="jbpm.task.hbm.xml" />
     <mapping resource="jbpm.identity.hbm.xml" />
    
  </session-factory>
</hibernate-configuration>

I read somewhere that the jbpm4_property table might not be initialized this way? True? If so, is there a known work-around?

Thanks

HI Jimmy.

If you want to do something what should access database,  you have to open an environment.  There is an easy way to do that things.

processEngine.execute(new Command() {
    public Object execute(Environment env) {
        // do any thing
        return null;
    }
});

Thanks!

Real problem turned out to be that I used a combination of mocked jBPM objects and 'real' ones. Silly.
