One part of the service passes a parameter ("myparam") to a .jsp page, which in turn calls a REST service including our myparam as a path parameter. The design flaw bit is that myparam should be passed as a form parameter, since it can be...

When something goes wrong (for example, the String is not a number but the letter 'a', or whatever) this method will throw an exception.
