integration of jsp applciation into Portal n database

Hi,

we are migrating an existing website to SAP EP and the existing website has lot of jsp applications deployed on tomcat. wat do you think would be a good idea?

1. to create url iviews of jsp pages that exists on my tomcat server. but the problem is that, lets say that a jsp form is a form, where i fill the fileds and press on submit, which calls a JSP again doing the server side job, but after execution, the portal itself is redirected to the response of the JSP replacing my portal page.....so what i am supposed to do in order to display the response in the same iview tray container.

2. lets say, i get the ear file and deploy it on my SAP j2ee engine itself and create an iview, but still i have the problem mentioned above...

so, in both the cases, I have to rewrite the code of jsp..am i right?

please correct me if i am wrong and let me know ur suggestions.

thanks
