The exception is telling you that the JSP and bean are doing something out
of the proper sequence. Setting the response type after sending some output
is the most likely cause.
What you're doing can be made to work. I used to do JSP work exactly this
way. But since getting all this sorted out is going to be a lot of work
anyway, you really should consider moving to something better than JSP.
See http://virtualschool.edu/wap for the rationale and code.
If you want to use dynamic binding between code and presentation, consider
integrating JWAP and Velocity (or similar template engine) as outlined
there.
