Well, the simple answer is that you're actually doing a GET, when your second servlet
is expecting a POST. Here's some code that might help.
We had a problem forwarding a person to a forums application. Because we use single
site login, we wanted to automatically log users into the forum, if they were logged
in. The problem was that the forum was expecting a POST, and our servlet was doing a
GET.
—---------------------------------------------------------------------------------------
URL u = new URL("http://my.forums.server/some/forums.cgi");
URLConnection c = u.openConnection();
// set the connection to do output to the connection
c.setDoOutput(true);
// get the output stream to write to the forums software
PrintWriter out = new PrintWriter(c.getOutputStream());
// Preparing buffer for setting data to the forums software
// writing data to the output stream
StringBuffer sBuf = new StringBuffer();
sBuf.append("UserName=");
sBuf.append(custNum);
sBuf.append("&Password=");
out.println(sBuf.toString());
out.close();
//Because the servlet is now the client in this case, we read in the
response from the forums into the servlet, then output to the client;
BufferedReader inStream
= new BufferedReader(new InputStreamReader(c.getInputStream()));
response.setContentType("text/html");
java.io.PrintWriter writer = response.getWriter();
String inputLine;
while ((inputLine = inStream.readLine()) != null) {
writer.println(inputLine);
}
writer.flush();
writer.close();
inStream.close();
—-----------------------------------------------------------------------------------------------------
There's probably a simpler way to do this, but this worked for us. This isn't exactly
what you're doing, but you might be able to use it.

I invoke a servlet from an HTML page using method = "POST" and ACTION = "URL
to the servlet1". It works fine.
Now suppose this servlet forwards the request to second HTML page (using
RequestDispathcher). The HTML page invokes second servlet using method =
"POST" and ACTION = "URL to the servlet2". It does not work. The browser
gives the error message "405 Method not allowed".
If I change method from POST to GET, it works fine.
Can you throw some light as to why this is happening.
