-----------------------------------------
Summary: IllegalArgumentException when forwarding request
Key: FELIX-5053
URL: https://issues.apache.org/jira/browse/FELIX-5053
Project: Felix
Issue Type: Bug
Components: HTTP Service
Affects Versions: http.base-3.0.0
Reporter: Sten Roger Sandvik
It seems to be a problem with forwarding requests in certain cases. I have the
following setup:
* Servlet A forwards the request to Servlet 2 (using RequestDispatcher).
* Servlet B writes to the response using an output stream
(HttpServletResponse.getOutputStream()).
When this happens I get an IllegalStateException from Jetty that basically
saying that the Writer cannot be closed since I have already used an
OutputStream.
The code that I think is wrong (or possibly not robust enough) is in
RequestDispatcherImp line 84.
{code}
if (!request.isAsyncStarted())
{
response.flushBuffer();
response.getWriter().close();
}
{code}
The line that causes trouble is:
{code}
response.getWriter().close();
{code}
We should probably check if we can actually close this writer or just ignore
the potential exception.
In my setup I have one servlet that writes to OutputStream using
HttpServletResponse.getOutputStream(). Then I have another servlet that
forwards the request to the first servlet.
