You can test what the page sends by using a reflection jsp/servlet, an invaluable tool for JSP development. Just search Google for a handly model of how to do this.
Also, to see it quickly, point your HTML form to itself, and select method=GET. You should see all the parameters being sent, including logon.x

Great, thanks!
New Controls:
<INPUT TYPE="image" ALT="Regent Logon" VALUE="Regent Logon" NAME="logonr" SRC="javascript:void(0);" WIDTH="140" HEIGHT="27" ALIGN="top" BORDER="0">
<INPUT TYPE="image" ALT="Member Logon" VALUE="Member Logon" NAME="logonm" SRC="javascript:void(0);" WIDTH="140" HEIGHT="27" ALIGN="top" BORDER="0">
New logonchoiceprocess.jsp:
if( request.getParameter("logonr.x") != null )
{
response.sendRedirect("regentlogon.jsp");
return;
}
else if ( request.getParameter("logonm.x") != null )
{
response.sendRedirect("memberlogon.jsp");
return;
}
else
{
response.sendRedirect("index.jsp");
return;
}
Hope it doesn't eventually bite me in the rear
