Adding Security to a Published Report

I have published a report and it runs great, however, I would like to add my own security to it.

This is what I have done.

1) I have added a "USER" parameter to the parameter page fex which is called by the published HTML.

2) The user enters a "USER" id and hits "SUBMIT" and the "USER" id is passed to the parameter page fex.

3) The parameter page fex validates the "USER" id passed to it against an Oracle table.

This works great, but I want the "USER" id to be passed to the published HTML page from a separate JSP application and have the published HTML page accept it and do an "auto submit" which will then pass the "USER" id to the parameter page fex.

How can I do this?

Thanks,

Leo ;-)
