theme frontpage: getOutputStream() has already been called for this response

[Greg Huber]

Hello,

Now with the frontpage theme we keep seeing this error message in the log 
file. 

StandardWrapperValve:invoke - Servlet.service() for servlet jsp threw 
exception
java.lang.IllegalStateException: getOutputStream() has already been called 
for this response
        at 
org.apache.catalina.connector.Response.getWriter(Response.java:601)
        at 
org.apache.catalina.connector.ResponseFacade.getWriter(ResponseFacade.java:196)

Have traced it to the index.jsp:

RequestDispatcher homepage =
            request.getRequestDispatcher("/roller-ui/rendering/page/"
+frontpageBlog);
homepage.forward(request, response);


If the old redirect method is used this message goes away:

response.sendRedirect(request.getContextPath()+"/"+frontpageBlog);

Front page seems to work ok all the same.

Cheers Greg
