Thanks Ronald and Pedro,
Your help is much appreciated.
I am trying the code you have posted with default configuration using
hibernate3.jar. And I am using the default configuration for HSQL database
only. If I connect to the HSQL manager I could see the process definition
"simple":
select * from jbpm_processdefinition;
However I get the following error "table not found" sql exception when I
execute the code: This suggests that the jbpm_processdefinition table is not
in the query. Am I missing something. If it is a trivial issue, please post any
pointers that help me progress.
