How to get Pocess from server

[sidkennedy]

Hello to all,
Here http://www.jboss.com/products/jbpm/docs/tutorial I found a description how to start a Process Instance on a server with that code snippet:

ExecutionService executionService =
 JbpmServiceFactory.getInstance().openExecutionService("AlbertEinstein");
executionService.startProcessInstance( "payraise" );
executionService.close();

My problem is that I can't find the ExecutionService. In which jar it can be found or is it replaced with another class in a newer verision?

greets
Sid

or in another way the question is: How can I connect to a JBoss-server(working with a mysql-DB) to get a process?

[sidkennedy]

meanwhile I found out that I can connect and get the ProcessDefinitions stored in the DB like this:

JbpmConfiguration config = JbpmConfiguration.getInstance();
JbpmContext context = config.createJbpmContext();
List processes = context.getGraphSession().findLatestProcessDefinitions();

but in the third line an exception is thrown.

java.lang.NoClassDefFoundError: org/hibernate/Session
at org.jbpm.persistence.db.DbPersistenceServiceFactory.openService(DbPersistenceServiceFactory.java:56)
at org.jbpm.svc.Services.getService(Services.java:136)
at org.jbpm.svc.Services.getPersistenceService(Services.java:175)
at org.jbpm.JbpmContext.getPersistenceService(JbpmContext.java:596)
at org.jbpm.JbpmContext.getGraphSession(JbpmContext.java:537)
....

what does that mean?

Means it cannot find the class org/hibernate/Session .
Looks like you haven't got the required hibernate jar files in your classpath.

meanwhile I discovered that the code above is only possible if that class was deployed to the JBoss AS. But I want to get a ProcessDefinition/Instance from outside the AS. How can I do this? With EJB? Or is there an easier way?

[dleerob]

As I said, check your jars. You can run that code outside JBoss AS. I run the same code in Tomcat. You can run it anywhere, as long as you have setup your classpath/libraries correctly.

Look at the deployment section in the documentation. Make sure you are referencing all relevant jar files.
