Hi,

I was wondering if it was possible to retrieve the instance name ( given to an instance of a ortlet by the Management Portlet ) of a portlet from JBoss?

I have a portlet which can be told at run time to point to the location of a video feed (multipart jpeg) and display it. I have many instances of this portlet pointing to different video feeds. When i reboot JBoss though the locations are lost because i am storing the location in a class variable. When the objects are reistanciated the location variable goes back to null.

My sneaky solution ( avoiding extra work ) is to name the portlet instances the location which they should be pointing to, when the portlets are displayed i hope to retrieve the intance name, and thus the location of the video feed.

It would also be useful if i could change the name of an instance from inside my portlet too.

My code is shown here. The doEdit method just displays a jsp page with a text input box.

public class ImageViewPortlet extends GenericPortlet {
 String imageLocation;

 protected void doView(RenderRequest renderRequest, RenderResponse renderResponse) throws PortletException, PortletSecurityException, IOException {
 renderResponse.setContentType("text/html");

 Writer writer = renderResponse.getWriter();

 if(imageLocation == null)
 imageLocation = "none";

 writer.write("<img src=" + imageLocation + "/>");
 }

 protected void doEdit(RenderRequest renderRequest, RenderResponse renderResponse) throws PortletException, PortletSecurityException, IOException {
 renderResponse.setContentType("text/html");

 try {
 PortletRequestDispatcher prd = getPortletContext().getRequestDispatcher("/jsp/ImageEdit.jsp");
 prd.include(renderRequest, renderResponse);
 }
 catch (Exception e)
 {
 e.printStackTrace();
 }
 }

 public void processAction(ActionRequest actionRequest, ActionResponse actionResponse) throws PortletException, PortletSecurityException, IOException {
 String imageLocation = actionRequest.getParameter("imageLocation");
 this.imageLocation = imageLocation;
 actionResponse.setPortletMode(PortletMode.VIEW);
 }

}
