I faced a problem regarding tasklist application deployment..
My bpel had a human task acitivity with a custom JSP for viewing task details.
I deployed the process using BPELConsole using Deploy New Process link.
Process worked fine. However, when I clicked a task name in tasklist application, it threw an error stating JSP was not found on the server.
I tried deploying the same process using JDev with the BPEL Server connection.
And to my surprize, the link started working.
Seems like, deployment using BPELConsole doesn't deply your custom JSP Pages for the worklist application. Where jdev also deploys the displayForms along with the BPEL Process.
