hi,
has anybody seen this error before ?. I created the JBPMConfiguration object
from a xml string (Copy and paste from User guide's Chapter 3 Database
example). Then i try to create a process instance and i get the error below. It
seems like if the persistence service was not available but i initializate
exactly as the example.

Creation of JbpmConfiguration Object

Instantiation of process

jbpmContext.newProcessInstance("SolicitudPrestamo");

(processInstance.getProcessDefinition().getTaskMgmtDefinition().getStartTask()
== null)
| {
| processInstance.signal();
| }
| else

| TaskInstance startTask =

processInstance.getTaskMgmtInstance().createStartTaskInstance();
| jbpmContext.save(startTask);
| }
| }
| finally
| {

| }
| }

Thanks in advance for your help.
