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:
java.lang.UnsupportedOperationException: use JbpmContext.save(ProcessInstance)
instead

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
Thanks,
Barbu
