We are trying to deploy a web application in Websphere 4.0. The application
gets deployed fine but at runtime it gives an error stating :
java.lang.IllegalStateException: Writer already
obtained
at
com.ibm.servlet.engine.srt.SRTServletResponse.getOutputStream(SRTServletResp
onse.java:337)
at
com.ibm.servlet.engine.webapp.HttpServletResponseProxy.getOutputStream(HttpS
ervletResponseProxy.java:98)
We get this error for all the files (Servlet or JSP's) that open an
outputstream, after or before doing an include in the request dispatcher
interface.
For Servlets this is the code snippet
public void doPost(HttpServletRequest request, HttpServletResponse response)
{
ServletOutputStream out;
out = response.getOutputStream();
out.println("<noscript>");
out.println("<meta http-equiv='refresh' content='0;url="+
System.getProperty("HTML") + "JScript.html'>");
out.println("</noscript>");
getServletContext().getRequestDispatcher(System.getProperty("FORWARDJSP")+"S
tatusBar.jsp").include(request, response); // it
fails at this line
out.println("</body></html>");
}
similiarly if we have a code like this :
public void doPost(HttpServletRequest request, HttpServletResponse response)
{
getServletContext().getRequestDispatcher(System.getProperty("FORWARDJSP")+"S
tatusBar.jsp").include(request, response);
ServletOutputStream out;
out = response.getOutputStream(); // it fails here
out.println("</body></html>");
}
the error in both the cases is :
java.lang.IllegalStateException: Writer already
obtained
at
com.ibm.servlet.engine.srt.SRTServletResponse.getOutputStream(SRTServletResp
onse.java:337)
at
com.ibm.servlet.engine.webapp.HttpServletResponseProxy.getOutputStream(HttpS
ervletResponseProxy.java:98)
The same files work fine in weblogic.
A quick response will be highly appreciated.
Thanks in advance

This is actually the correct implementation. According to the Servlet 2.3 spec (I know WAS 4.0 only implements 2.2, but it's the same)
IllegalStateException - if the getWriter method has been called on this response
So, I'm wondering since your including a JSP page and JSPs intrinsically have access to the 'out' variable and the 'out' variable is a JspWriter object which is probably created from the reponse.getWriter() call, could the IllegalStateException be correct?
