Custom filter calling Pipeline servlets

Question

Hi,
Can we invoke the pipeline servlets from our custom filter without using the PageFilter, if we can please explain how to do that.
And how to get the DynamoHttpRequestServlet as passing thru the pipeline we will get Dynamo request only.

Answer 1

I have been following up this thread along with some other posts also from you on similar issue and thought of one approach. Although I am not sure if it is going to work or not due to any internal dependency on something which I may not know. But still you can try something like this to invoke the pipeline by calling HeadPipelineServlet from your own filter and see if it serves your purpose.
//component path to refer atg.servlet.pipeline.HeadPipelineServlet
String piplineStartServletPath = "/atg/dynamo/servlet/dafpipeline/DynamoHandler";
//your filter implementation
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException
  //try invoking HeadPipelineServlet
  Servlet startServlet = (Servlet)Nucleus.getGlobalNucleus().resolveName(piplineStartServletPath);
  if(startServlet != null)
    startServlet.service(request, response);
  //once HeadPipelineServlet is called check from the request attribute to see if we got the DynamoHttpServletRequest
  DynamoHttpServletRequest drequest = (DynamoHttpServletRequest)request.getAttribute("atg.servlet.request");
}
