USING APACHE STURUTS BRIDGE WITH ORACLE PORTAL FOR STRUTS - JSR 168 PORTLET

Question

I am trying to develop a JSR - 168 compliant portlet which uses struts framework.I am using APACHE STRUTS BRIDGE to run the application in my ORACLE 10.1.4 Portal server.While doing the configuration accoring to the documentation given in URL http://www.ja-sig.org/wiki/display/PLT/Struts+Bridge
(apache struts bridge), i was asked to add an <init-param> entery in the portlet.xml file to get the ServletContext.So i need to know where is the ServletContextProvider implementation class which implements ServletContextProvider available in Oracle AS so that i can use that to get the ServletContext and use it furthur.
Thanks

Answer 1

you could write your own implementation class for the ServletContextProvider interface and fill in the portlet.xml with the class you class
It could be written as follows:
package Edmunds.com.portal.bridges;
import javax.portlet.GenericPortlet;
import javax.portlet.PortletRequest;
import javax.portlet.PortletResponse;
import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletRequestWrapper;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpServletResponseWrapper;
/* note that PortletApplicationImpl is oracle version of portletContextImpl */
import oracle.webdb.wsrp.server.PortletApplicationImpl;
import org.apache.portals.bridges.common.ServletContextProvider;
* PortalServletContextProvider supplies access to the Servlet context of Oralce Portal Portlet.
public class PortalServletContextProvider implements ServletContextProvider {
public ServletContext getServletContext(GenericPortlet portlet)
return ((PortletApplicationImpl) portlet.getPortletContext()).getServletContext();
public HttpServletRequest getHttpServletRequest(GenericPortlet portlet, PortletRequest request)
return (HttpServletRequest) ((HttpServletRequestWrapper) request).getRequest();
public HttpServletResponse getHttpServletResponse(GenericPortlet portlet, PortletResponse response) {
return (HttpServletResponse) ((HttpServletResponseWrapper) response).getResponse();
}
