Abstract Portal Component: How to inclue a HTML file into the response?

Question

Hi experts,
i am currently working on the problem, that i want to access KM inside my AbstractPortalComponent in order to retrieve a HTML File.Afterwars i want to include this file into my IPortalComponentResponse.
IPortalComponentResponse offers the method include(IPortalComponentResponse , IResource)
Is it possible to use this method to achieve my goal?
I have tried this approach:
IResourceContext resourceContext = new ResourceContext(requester);
RID rid = RID.getRID("/documents/test.gif");
IResource resource = ResourceFactory.getInstance().getResource(rid,resourceContext);
response.include(request,resource);
But the problem is that this IResource doesn't match the IResource that is needed for this method.
My IResource belongs to com.sapportals.wcm.repository.IResource
But the Methos just works with com.sapportals.portal.prt.resource.IResource
So can you help me on this one?:)
With Best Regards
Marcus

Hi,
read the contents of the resource and put them to the output.
Dumb but working piece of code:
private String renderResource(IResource resource, boolean html) {
          StringBuffer buf = new StringBuffer("");
          try {
               IContent content = resource.getUnfilteredContent();
               if (content != null) {
                    InputStream is = content.getInputStream();
                    byte[] bytes = new byte[(int) content.getContentLength()];
                    int i = is.read();
                    int count = 0;
                    while (i != -1) {
                         char b = (char) i;
                         bytes[count] = (byte) i;
                         count++;
                         i = is.read();
                    buf.append(new String(bytes, "UTF-8"));
                    if (html) {
                         buf.append("</br>");
                    } else {
                         buf.append('\n');
          } catch (Exception e) {
// do something
          return buf.toString();
hope this helps,
