问题
In the default "evaluation" example in jBPM 5.4, I want to replace the actors "john" and "mary" with actors defined in a file or in a database, if possible, through the jbpm web designer. How can I do that? I have searched the web and the forums and I found no solution for this. Thanks for your help.

You can integrate mysql with jbpm5 as shown here
Also you can write java handlers to fetch data from files or databases and then use #{expression} to assign actor id dynamically.
Comment if anything is not clear.
