Programmatically assigning a human task to a user/role in runtime

[arunvg]

Hi All,

I am trying to enhance the JBPM5 Web Example ( http://community.jboss.org/people/bpmn2user/blog/2011/09/21/jbpm5-web-example) for the technical evaluation of  JBPM .With the support of the forum and the previous discussions I was able  the set up the   example  in Jboss 7 ,Oracle 11 g environment .

Further to this I have to demonstrate the capability of programmatically assign tasks to various roles and users . As of now the example shows that the Assignment of tasks to the users

are done in the bpmn file

as below

<potentialOwner>

        <resourceAssignmentExpression>

          <formalExpression>john</formalExpression>

        </resourceAssignmentExpression>

</potentialOwner>

As the configuration of users and roles in a customer application is bound to change  can we programmtically assign a task to a user  or role after checking the (runtime) configurations.It would be very difficult and hindering to propose that the User/Roles can be changed only by changing the process definition that is the BPMN file.

Or in brief

I want to seperate User/Role  assignements from the process definition and want to determine the User/Role in runtime to which the  task is assigned. Is it possible Any hint ?

Thanks for the help

Hi Arun,

     You can use expression #{userName}  as actorid where you are currently passing krisv and pass the userName as parameter at the time of creation of the process. For that you have to create the process variable named userName. And also it is essential that you add that user name to the taskSession.

         Or the other way you can use local task server and you do not need to add that user to taskSession. for that you have to use jbpm5.2 local task server.

          You can study the example https://community.jboss.org/people/bpmn2user/blog/2011/12/18/jbpm5-web-example--local-human-task for local task server.
