--------------------------------------------------------------
For days now I am struggling with this issue of integrating Spring 3 and JBPM 4.

Apparently the application fails each time when I try to perform an action on one of the services, such as the repository service or the execution service.
By doing form search I found out that there is a documented issue JBPM-2710.

I have tried the solution as documented below.

still the problem persists. I tried to step through the code and I found that the issue is in the SpringTransactionIntercepter. Apparently no matter what I set in the jbpm.cfg.xml the transactionName is always null.

Class
=============
...

  @Autowired
    @Qualifier("jbpmExecutionService")
    private ExecutionService executionService;

...

executionService.startProcessInstanceByKey(name, variables); <----nothing happens here and in the spring intercepter

Please help me in trying to resolve this. Thanks
