Invoking JBPM-3.2.2 Process from standalone java client

[soumya_in]

Hi,

I am using JBPM jpdl 3.2.2. I have a requirement that a user logs into some web portal and sumbits a quotation payload which then will invoke a jpdl deployed process that will process that document.In the version 3.0.4 there is some code in HomeBean.java in java-webapp that states how to call a process instance,but is it still applicable for this version?

Please provide some documentation or sample code for achieving the same.

Thanks,

no... it is not aplicable anymore. There are lots of testcases in the jbpm source that show what to do instead.

can u name one of them or a certain portion of code-snippet that u want to stress

[kukeltje]

the JBPMContext is the one you want to use...

btw.. .these basics are in the docs as well:

Thanks Ronald for your response.
I followed the testcase as u instructed and run it successfully.But the problem is when I tried to find those 'Hello World' process instance from the database I can't find. Does this deployment a dummy one or it is deployed somewhere else or I am doing something wrong!

Hi All,
I was able to start a process from a standalone java client by following the given steps:-
1. Migrated JBPM Database schema to Oracle 10g using the given oracle script.
2.Redeployed the jbpm-console.war by making changes in the jbpm-console/web-inf/classes/hibernate-cfg.xml file to redirect the application to the oracle DB.
3. Executed the following piece of code-

jbpmConfiguration = JbpmConfiguration.parseResource("default.jbpm.cfg.xml");
 JbpmContext jbpmContext=jbpmConfiguration.createJbpmContext();
 GraphSession gpsession=jbpmContext.getGraphSession();
 ProcessDefinition pdef=gpsession.findLatestProcessDefinition("<process-name>");
 System.out.println("PROCESS DEFINITION ID" + pdef.getId());
 ProcessInstance processInstance = new ProcessInstance(pdef);
 Token token = processInstance.getRootToken();
 token.signal();//starts a task
 jbpmContext.close();

Thanks,
Soumya.
