How to Submit Partner Application Form to Partner Application

Question

When creating a partner application as a portlet, when we submit the form it gets submitted to the Portal server instead of the Partner Application server and as that page does not exist on the Portal Server. We get 404 error, Page not Found.
We wanted to use this application as a portlet without making any changes to the application, but looking at some examples it seems we will have to make some changes to the application to make it work as portlets. The changes I am talking about are following which we don't want to make as applications already exist.
<form method=post
action="<%=HttpPortletRendererUtil.htmlFormActionLink(request, HttpPortletRendererUtil.PAGE_LINK)%>" name='mainform' onsubmit='return validateallfields(this)'>
<%=HttpPortletRendererUtil.htmlFormHiddenFields(request,
HttpPortletRendererUtil.PAGE_LINK)%>
<%=UrlUtils.emitHiddenField(HttpPortletRendererUtil.portletParameter request ,
"next_page"),"/htdocs/sosportlet/createticket.jsp")%>
Also one more thing is I am not able to use the URL renderer, as with URLRenderer I am not able to get the information about the Single Sign On User.
So currently I am using the
<showPage class="oracle.portal.provider.v2.render.http.ResourceRenderer"> in the provider.xml file.

The servlet or JSP page you are sumbitting to is specified by the action="..." parameter of the form tag...
In that servlet/page you do a few things:
1) validate the input:
String s = request.getParameter("name of formelement here");
if (s == null) {
//handle null-string here...
2) put it in database
... create driver
... open connection
... produce ResultSet
