How to call a workflow form a JSP?

How can we call a workflow from a JSP?

a) Through click a link in JSP.

b) Calling it form JSP scriplet conditionally.

Can anyone give me example?

for example, I have a custom JSP (contract.jsp), where I perform some updations and I need to call a workflow form that JSP, which will perform some other task.

Thanks in advance
