jsp to jca

Hi,

I have an Jca program which has 3 input params and one output param. Its works fine when I hard code those values. But now i need these values as input from the user (user will be entering these values). How to get these values from a jsp page?

Can anyone give me an example of the jsp page with 3 inputs and passing that value to bean and then to jca. I know how to pass the exportparams to a jsp.

Thanks,
