Error in Struts Application, Form Submit

Question

I've developed a simple struts application which allows user to key in inputs thru a form(registration.jsp), submit n display e inputs keyed in in another page(details.jsp).
i'd succesfully integrate e pdk-struts application to portal, but wen i click on 'Submit', my action r not performed, not directed to my details.jsp, neither do it shows any error.
However, one thing i realised is tat wen integrated to portal, e codes for my action r changed:
registration.jsp
<html:form action="/register" focus="name">
after integrated wit Portal, it was translated to:
<form name="registerForm" method="post" action="http://smeagel:7778/portal/page">
<INPUT TYPE="hidden" name="_pageid" value="6,3,6_22" />
<INPUT TYPE="hidden" name="_dad" value="portal" />
<INPUT TYPE="hidden" name="_schema" value="PORTAL" />
<INPUT TYPE="hidden" name="_piref6_108279_6_3_22.strutsAction" value="register.do" />
After Submit button was clicked, i was directed to a new URL, http://smeagel:7778/portal/page
Any solutions??

<showPage class="oracle.portal.provider.v2.render.http.StrutsRenderer">/register.do</showPage>
</renderer>
</portlet>
</provider>
I'd saw some example, which using <defaultAction>, however, wen i put in <defaultAction>/register.do</defaultAction>
i'll have error in my Provider Test Page. Validation Unsuccessful.
Error: Class oracle.portal.provider.v2.render.http.StrutsRenderer has no set or add method for tag "defaultAction"
Is <defaultAction> a necessary tag? Is tat e reason y my application isnt running?
