ShowDocServlet Class
DEPRECATED
- 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:
contentHome
: Specifies the default JNDI content home name.
If this is specified, then all contentHome request parameters will be
ignored. If contentHome is not specified as either an init or request
parameter, the default DocumentManager home will be used (which is
"java:comp/env/ejb/DocumentManager").
closeStreams
: true to have the servlet close output
streams when done, false to not. This defaults to false.
This understands 2 request parameters:
contentHome
: Specifies the JNDI content manager home name
to look for the document at, if the contentHome init parameters isn't
specified.
contentId
: Specifies the identifier of the document to
display. If not specified, an error message is displayed instead.
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"
.

ShowDocServlet
public ShowDocServlet()
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.
