Thanks, but why in the documentation here http://docs.jboss.org/jbpm/v5.2/javadocs/ we can't find the classes you give me :
org.jbpm.process.core.impl.ProcessImpl
and
org.jbpm.process.core.Process
and
org.jbpm.workflow.core.impl.WorkflowProcessImpl ??
why in the documentation there is just interfaces not classes ??
i want to integrate a workflow in webapp that's why i search to understand the JBPM API ... in your opinion what's classes or interface needed to manage a process from a simple servlet ?
thanks a lot
