I am using jbpm3.0. in process definition file, the code like: <controller> | <variable name="item"/> | <variable name="quantity"/> | <variable name="address"/> | </controller> these data are saved to table jbpm_variableinstance, but I donn't want to use this in my application, because we already have customizd form to collect information of user entered. I want to know how to make relations between jbpm table with our existed table such as ppp_info, how to save form data to ppp_info and also keep the relations with jbpm_variableinstance and how to retrieve the data from ppp_info with a taskInstanceId?
