Hi at all when iam trying this:

ProcessInstanceQuery query = new ProcessInstanceQueryImpl();
List<ProcessInstance> list = query.processDefinitionId("procesDefinitionId").list();

i get this exception:

org.jbpm.api.JbpmException: no environment to get org.hibernate.Session
     org.jbpm.pvm.internal.env.EnvironmentImpl.getFromCurrent(EnvironmentImpl.java:197)
     org.jbpm.pvm.internal.env.EnvironmentImpl.getFromCurrent(EnvironmentImpl.java:190)
     org.jbpm.pvm.internal.query.AbstractQuery.untypedList(AbstractQuery.java:70)

     org.zkoss.zk.ui.impl.UiEngineImpl.execCreateChild0(UiEngineImpl.java:620)

<jbpm-configuration>
    <import resource="jbpm.default.cfg.xml" />
    <import resource="jbpm.tx.hibernate.cfg.xml" />
    <import resource="jbpm.jpdl.cfg.xml" />

    <import resource="jbpm.console.cfg.xml" />
    <import resource="jbpm.jobexecutor.cfg.xml" />
