RE: Tomcat does not respond
I use the ServletOutputStream because I need to write binary directly in the response while with the PrintWriter I can only write character text to the client. I don't understand the reason for this exception since I don't use the JsonView class for the requests that return a binary as output. -Original Message- From: Caldarale, Charles R [mailto:chuck.caldar...@unisys.com] Sent: giovedì 28 maggio 2009 15.15 To: Tomcat Users List Subject: RE: Tomcat does not respond From: Diego Castorina [mailto:di...@quince.nl] Subject: RE: Tomcat does not respond SEVERE: Servlet.service() for servlet springapp threw exception java.lang.IllegalStateException: getOutputStream() has already been called for this response at org.apache.catalina.connector.Response.getWriter(Response.java:604) at org.apache.catalina.connector.ResponseFacade.getWriter(ResponseFacade.java:198) at org.springframework.web.servlet.view.json.JsonView.renderMergedOutputModel(JsonView.java:60) It would seem like the first thing you need to do is fix your webapp so it doesn't provoke the above error.

RE: Tomcat does not respond
Thanks for the tip. How can I write this wrapper? I can have different kind of client so I cannot encode the binary as string and decoding it on the client side. -Original Message- From: Caldarale, Charles R [mailto:chuck.caldar...@unisys.com] Sent: giovedì 28 maggio 2009 16.12 To: Tomcat Users List Subject: RE: Tomcat does not respond From: Diego Castorina [mailto:di...@quince.nl] Subject: RE: Tomcat does not respond I use the ServletOutputStream because I need to write binary directly in the response while with the PrintWriter I can only write character text to the client.

From: Diego Castorina [mailto:di...@quince.nl] Subject: RE: Tomcat does not respond How can I write this wrapper? I don't know Spring, but perhaps it already offers this capability. Otherwise, Chris S recently posted a wrapper that, IIRC, will do this.

The Tomcat server runs fine in several days (could be 1 or 2,3,4 days unexpectedly) but then it does not respond any request and produce any output (also no error code). It only happens to me only on that server. The server is running Windows 2000 server, 2GB RAM, 4 CPUs. I've spent days and nights and not yet work out any solution. Is there anyone having the same problem and pointing me a way to solve it ? My customer is pressuring me too much for this.
