Ok, reading a bit more it looks like i need to create a TaskClient to access the task service and from there i should be able to then redirect things to my portal application and progress the process.
Thanks for the help.
So another quick question related to this, if i wanted to use the hornetq task service do i need to register the workitem handler or can i use the default one. (Following this example - http://docs.jboss.org/jbpm/v5.2/userguide/ch.Human_Tasks.html)
I prefer the benefits of using hornetq.
Thanks
