ProcessInstance persistence from org.jbpm.db.JbpmSession doe

[barbu]

Hello,

Please help me on an error as follows:

I need to save a ProcessInstance from org.jbpm.db.JbpmSession. I obtained an error as follows: java.lang.UnsupportedOperationException: use JbpmContext.save(ProcessInstance) instead

Below there are the source code:

package wse.test.jbpm;

import junit.framework.TestCase;

import org.jbpm.db.JbpmSessionFactory;
import org.jbpm.db.JbpmSchema;
import org.jbpm.db.JbpmSession;
import org.jbpm.graph.def.ProcessDefinition;
import org.jbpm.graph.exe.ProcessInstance;

public class JBPMProcessDefinitionTestC extends TestCase
{
 public void testJbpmSessionFactory()
 {

 // Get a JBPM session connected to a database.
 // create a process definition (from XML) and store it to the database.
 JbpmSessionFactory jbpmSessionFactory = JbpmSessionFactory.getInstance();
 JbpmSchema jbpmSchema = new JbpmSchema(jbpmSessionFactory.getConfiguration());
 jbpmSchema.createSchema();

 JbpmSession jbpmSession = jbpmSessionFactory.openJbpmSessionAndBeginTransaction();
 ProcessDefinition processDefinition = ProcessDefinition.parseXmlString(
 "<process-definition name='B'>" +
 " <start-state name='start'>" +
 " <transition to='one' />" +
 " </start-state>" +
 " <state name='one'>" +
 " <transition to='end' />" +
 " </state>" +
 " <end-state name='end' />" +
 "</process-definition>"
 );
 jbpmSession.getGraphSession().saveProcessDefinition(processDefinition);
 jbpmSession.commitTransactionAndClose();

 // Get a JBPM session connected to a database.
 // Reload the previously save definition from the database.
 // start a process instance, move one step, save it to the database.
 jbpmSession = jbpmSessionFactory.openJbpmSessionAndBeginTransaction();
 processDefinition = jbpmSession.getGraphSession().findLatestProcessDefinition("B");
 ProcessInstance processInstance = new ProcessInstance(processDefinition);
 assertEquals("start", processInstance.getRootToken().getNode().getName());
 processInstance.signal();
 jbpmSession.getGraphSession().saveProcessInstance(processInstance);
 jbpmSession.commitTransactionAndClose();

The eclipse Failure Trace is:

I worked with: eclipse 3.1.2, jbpm-starters-kit-3.1, hibernate-3.1, jboss-4.0.4RC1, jdk1.5.0_06, junit-3.8.1 on XP SP1

jbpmSession is deprecated. This may be your problem.

Yes, starting form jBPM 3.1 you should use JbpmContext instead

Thank you very much.
