Hi,
I am trying to integrate JBPM 5.3 with oracle 11 g r2.I am getting schema created properly
on the database with below tables.
I have created a human task sample workflow with web designer and deployed from there.I am
able to start the flow but then when I login with the owner of humantask and try to
retrive the personal task,I am getting errors.
I have attached server log file and error snapshot.
Where as I am able to run Evalution process successfully for jbpm 5.3 with oracle as
database.
Kindly direct me on this problem for solution.
