Hi,
I try to run a HessianServlet inside WebSphere 6 and get this exception.

Caused by: java.lang.IllegalStateException: SRVE0199E: OutputStream already obtained
at com.ibm.ws.webcontainer.srt.SRTServletResponse.get Writer(SRTServletResponse.java:462)
at com.ibm.ws.webcontainer.webapp.WebApp.sendError(We bApp.java:2488)

I'm not manipulating or acquiring any response streams in my hessian servlet. Is there a fix or workaround for this problem in hessian?

thank you,
mynzai

Ok, sorry. I realized after the first post that it might not be in the right group. Not sure which group would best know the answer to this problem.

Apparently there isn't one. :(

Looks like this is caused by the WebSphere web engine trying to write text content to the servlet response after Hessian already wrote binary content response. Such mixing of Writer/OutputStream usage is not allowed by the Servlet spec.

The question is: Why does WebSphere try to write to the servlet response Writer in the first place? This seems to be caused by some error handling... Do you maybe have a JSP error page configured that tries to kick in even for Hessian requests?
