RE: Can't get Servlet Inputstream
The Servlet is listening for requests. When a request is made it sends a response.
The request is one of the parameters to the servlet, and you can tell that it has
content in it, but you can not get the content from the request with getInputStream
and I don't know why that is. Maybe I am missing something, but it should work.
Thank you,
George

I´m don´t understand why you need the InputStream from a Servlet
once servlets just write text to client´s browser. And besides, what are you
expecting to get from InputStream? To get FORM parameters and cookies and
related things from client side you must call resquest methods.

RE: Can't get Servlet Inputstream
As far as the exception it depends on whether I try to do a getInputSteam or getReader
call on the request. If I use getReader, I get an exception that says getInputSteam
has already been called. If I change the call to getInputStream I always get nothing
back.
Thank you,
George

I have to go now, but I can provide the exact exception thrown later.

Can't get Servlet Inputstream
I am converting a servlet from using Jigsaw's Servlet methods to Tomcat's and I am
curious why calling getInputstream on the request in Tomcat returns null. This calls
works fine in Jigsaw receiving the same XML data, but returns null in Tomcat. Any
help would be appreciated. Below is a simple example of the code that is failing:
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException
{
...
System.out.println("Content lenght = "+request.getContentLength()); // this line works
ServletInputStream in = request.getInputStream();
// this returns null, why?
...
}
BTW - I can read the request header and content length fine from the request, just
can't get the inputstream.
Thank you,
George
