Struts portlet redirects for outside portal

Question

We have a standard Struts app, with many standalone pages. The idea is to wrap each page (.do) in a different portlet. Each page redirects to a validation page, and back to itself using struts.
Whe I do any redirect in the page, the browser navegates back to the page, but opening the page outside the portal.
How can I redirect correctly to the portlet?

Answer 1

I am using the standard redirection from struts. See above the configuration from struts-config.xml:
?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">
<struts-config>
     <data-sources />
     <form-beans>
          <form-bean name="velocidadeActionForm" type="xxxx.form.VelocidadeActionForm" />
     </form-beans>
     <global-exceptions />
     <global-forwards />
     <action-mappings>
          <action
               attribute="velocidadeActionForm"
               input="/WEB-INF/jsp/VelocidadeForm.jsp"
               name="velocidadeActionForm"
               parameter="metodo"
               path="/velocidadeAction"
               type="xxxx.action.VelocidadeAction">
               <set-property property="cancellable" value="false" />
               <forward
                    name="same"
                    path="/WEB-INF/jsp/VelocidadeForm.jsp"
                    contextRelative="true" />
     </action>
     </action-mappings>
     <message-resources parameter="xxxx.ApplicationResources" />
</struts-config>
I am creating the WebService in ALUI referencing the action form:
/xxxx/velocidadeAction.do
