Exception when trying to post to a page

Question

In NetD we created and submitted a form with JavaScript.
The form looked something like this
<FORM ACTION=pgXYZ METHOD=POST>
<INPUT TYPE=hidden NAME=SPIDERSESSION VALUE=12345>
</FORM>
So now in Jato, we're trying to do the exact same thing,
except that instead of SPIDERSESSION, we use the three Jato
variables. Now the form is like this:
<FORM ACTION=pgXYZ METHOD=POST>
<INPUT TYPE=hidden NAME=GXHC_GX_jst VALUE=12345>
<INPUT TYPE=hidden NAME=GXHC_gx_session_id_ VALUE=12345>
<INPUT TYPE=hidden NAME=pageAttributes VALUE=12345>
</FORM>
Notice we're not submitting to a handler, but just to the page itself.
When we do this, we get an exception:
[02/Oct/2001 16:29:59:4] error: Exception: SERVLET-execution_failed:
Error in executing servlet portalServlet:
javax.servlet.ServletException: The request was not be handled by the

So what are we missing??

Hi Mark
You are trying to submit to a view bean using java script right ?
Notice we're not submitting to a handler, but just to the page itself.You are actually submitting the request to your JATO selvlet base, is that
you intention ?
The exception is being thrown because there is no request handler found.
If you are trying invoke a handleBtnXXXmethod then your form action would
look something like,
<form method="post" action="../myServlet/pgMyPage?pgMypage.btnMyButton=">
This adds to the request an appropriate handler as a parameter. Another
option could be to add a hidden field
with the same name as your button.
Attempting to post the form without specifying a request handler will not
work eg:
<form method="post" action="../myServlet/pgMyPage">
This throws a ServletException("The request was not be handled by the
specified handler")
because you are doing a post to ViewBean from a form which implies youwant
to handle some kind web action.
The way JATO enforces this is to check for the prescence of pageAttributes
in the request (implemented using hidden fields)
which you have in your form.
