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. If Spring intends to use the Writer associated with the Response object, you cannot use the OutputStream (and vice versa). Fix the other parts of your webapp to use Response.getWriter(), not Response.getOutputStream(). - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

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. Then you may need to resort to your own wrapper for the Response object, and it can coordinate the use of the Writer with the OutputStream. 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. The stack trace clearly shows you're mistaken. You may not use it explicitly, but something you're using in Spring obviously does. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Tomcat does not respond
Hi everyone, We are currently running Tomcat 6.0.14 on a Ubuntu Server 8.04 and Java 1.6. Two applications are running: - One of them uses Spring MVC and Jackrabbit providing RESTful API - The second is a client of the former with no database but it is a Grails application The server completely stop responding around 2 times a day but nothing emerges from the logs. It hangs on every request, even on the index.htm containing a Hello World Any clues?
