hello all,

i posted a question regarding the Stackoverflow error. but i got no help.

thought i will explain my problem in more detail.

i have an adduser.jsp which is invoked thru a href in a normal html page.

this adduser.jsp displays a form.

there is formbean and actionclass for this adduser.jsp and the mapping is fine.

currently, after i am into this problem, the action class does nothing except mapping the form to AddUser and forwarding to adduser.jsp

when i invoke this jsp, i get the following error...

null
java.lang.StackOverflowError
at allaire.jrun.servlet.ForwardRequest.getParameterNames(../servlet/ForwardRequest.java:206)
at allaire.jrun.servlet.ForwardRequest.getParameterNames(../servlet/ForwardRequest.java:206)
:

this runs for some 100 lines or so and then

at org.apache.struts.util.RequestUtils.populate(RequestUtils.java:734)
at org.apache.struts.action.ActionServlet.processPopulate(ActionServlet.java:2050)

at org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:490)
:

this runs for another 100 lines or so.

i figured that the line in org.apache.struts.util.RequestUtils.java has the following line

            multipart.setServlet(servlet);
            multipart.setMapping((ActionMapping)
                                 request.getAttribute(Action.MAPPING_KEY));
           **** request.removeAttribute(Action.MAPPING_KEY);******//this is the line

i did a system.out for Action.MAPPING_KEY and it is having the correct mapping.

if i give a forward to another .jsp page, it works fine.

so i thought the error is in my .jsp and removed everything except for <html> and <head> tags. nope no use.

can anyone help me or point me to a hint.

thanks,

rama.
