ShowDocServlet Class

public class ShowDocServlet

    extends com.bea.content.manager.servlets.ShowBinaryServlet

A servlet which will output a document to the client.

This will act like the ShowBinaryServlet. If the Node is not found in the repository, then this will perform the old behavior of using a DocumentManager

This understands 2 init parameters:

This understands 2 request parameters: This will also check the PATH_INFO for the contentId, if it's not found in the request parameters. This will put the contentHome from the request parameter in the session at "com.bea.p13n.content.document.contentHome".

Method Detail

doPost(HttpServletRequest, HttpServletResponse) Method

public void doPost(HttpServletRequest req, 
                   HttpServletResponse resp)
throws ServletException, IOException
Request entry point.

Override to first try the ShowBinaryServlet method to access the new content repository first. If that fails to find the Node, then this will access a ContentManager.

This method gets the contentId and contentHome. From that, it gets a Document object, from which, it outputs the document's content bytes to the output stream.

It will set the Content-Type, Content-Length, and Content-Disposition headers on the response to try to get the browser to do the correct thing.

Overrides
ShowPropertyServlet.doPost(HttpServletRequest, HttpServletResponse)
