Are you using extension mapping, with the extension ".cm"? If so, then your
infinite loop is happening because you are forwarding from the action right
back to the same action, instead of to the JSP page. Change your forward to
reference the JSP instead of the action, like this:
<forward name="success" path="/adduser.jsp"/>
and things should start working normally.

Subject: infinite loop
hi all,
In continuation to my post yesterday,
The following is my code. The flow is fine till Forwarding to Success
and then instead of displaying, it starts again from the begining.
If i remove the if condition in validate method then it displays the
form with errors which is fine.
am i doing something wrong????
thanks,
rama.
Mappings:
<!-- FIP User Profile Page bean -->
<form-bean name="addUser"
type="com.niku.cm.action.AddUser"/>
<!-- FIP User Profile Page -->
<action path="/adduser"
name="addUser"
validate="true"
input="/adduser.jsp"
type="com.niku.cm.action.AddUserAction">
<forward name="success" path="/adduser.cm"/>
</action>
adduser.jsp:
<html:errors />
<html:form action="/adduser?action=save" focus="fullname">
<table width="55%" border="0" cellspacing="1">
<tr>
<td class="fieldname" width="16%">Full Name*
</td>
