Hi Friends and Kukultjee sir,
I am new to jbpm.Hope u will help me in solving this Problem..
I am using Jbpm-3.1.4 and Jboss 4.0.2 as apllication server.I developed
following par file and it is running successfully with hardcoding values...
Now,what i am doing is i am inserting the values from the database using
stored procedure directly to the 'PMAcceptence' node which contains
three textboxes i.e projectname,plan status and commentByPm.after
executing the storedprocedure the corresponding values are populated in
these textboxes..Up to Now..it's Ok..But after clicking the 'accept' button
it is generating the following errors..
<!--Processdefinition.xml-->
<?xml version="1.0" encoding="UTF-8"?><process-definition
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
