Parallel execution in a workflow

[ashish]

I am facing a very typical problem .I have a workflow in which depending on some conditons,2 or more methods need to be executed parallely.Since the EJB1.1 specs dont allow multithreading,my second method will not execute until the previous one returns the control. Any ideas as to how to achieve this or else any workaround to this problem? Thankx Ashish
