Re: bad content type mod_jk 1.2.27
Hi all, I have tried with apache 2.0.63 and modjk 1.2.6 and the result is the same. Someone can help me to identify which tomcat class set the content type about a request? I want to add a log on source in order to understand why the same request have two different response (content type text/html or bad text/plain) with random frequency.

Re: bad content type mod_jk 1.2.27
Hi, in effect in the case of Excel download I set Header after I send the output stream because I do not know that tomcat start to flush before controller return. Now I have fixed this. But I don't understand why I have mime type problem with other normal page. An other repetitive case with same problem , is a controller where I upload and read an excel and I return to a normal page: the page source is printed on screen. I attach a souce fragment, my application log that show the output point CI SONO DEGLI ERRORI NELL'INPUT.. and catalina.out that contains modjk logs. http://www.nabble.com/file/p20957484/source.txt source.txt http://www.nabble.com/file/p20957484/myApplication.log myApplication.log http://www.nabble.com/file/p20957484/catalina.txt catalina.txt Thanks, Marco Rainer Jung-3 wrote: Hi Marco, marcobalc schrieb: Hi, now I have the stacktrace but the problem is that the stack do not involve my classes :| java.lang.Throwable: Stack Info at org.apache.jk.core.MsgContext.action(MsgContext.java:263) at org.apache.coyote.Response.action(Response.java:183) at org.apache.coyote.Response.sendHeaders(Response.java:380) at org.apache.catalina.connector.OutputBuffer.doFlush(OutputBuffer.java:305) at org.apache.catalina.connector.OutputBuffer.close(OutputBuffer.java:273) at org.apache.catalina.connector.Response.finishResponse(Response.java:492) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:310) at org.apache.jk.server.JkCoyoteHandler.invoke(JkCoyoteHandler.java:190) at org.apache.jk.common.HandlerRequest.invoke(HandlerRequest.java:283) at org.apache.jk.common.ChannelSocket.invoke(ChannelSocket.java:767) at org.apache.jk.common.ChannelSocket.processConnection(ChannelSocket.java:697) at org.apache.jk.common.ChannelSocket$SocketConnection.runIt(ChannelSocket.java:889) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:690) at java.lang.Thread.run(Thread.java:619) Any idea? i'm going crazy on this problem :( Could you please post a more complete part of the log file, when used with the increased log level I posted to you earlier in this thread.

Re: bad content type mod_jk 1.2.27
Hi,
do you mean that I need to rebuild tomcat with a new log?
At the moment I have reproduced the problem with an MultiActionController
with this default method
public ModelAndView init(HttpServletRequest request, HttpServletResponse
response, RegistrationsSearch command)
throws Exception {
log.debug(isCommitted ?? +response.isCommitted());
return new ModelAndView(getInputView());
}
if I call repeatedly this method now and then the log
log.debug(isCommitted ?? +response.isCommitted());
write true, so the response was already committed.
Regards,
Marco

Not really. But since we know, we can detect the commit in class
org.apache.jk.core.MsgContext, method action(), you can add there the
output of a stack. So each time some code calls commit, you can see
exactly where the call comes from.

Re: bad content type mod_jk 1.2.27
Hi,
I have found one other interesting information: If the Excel is very small
the problem do not appear. If the Excel is more big (some kb) the stack
trace with the error appear.
I think that should be a buffer problem but I don't know how to locate the
root cause.
regards
Marco

bad content type mod_jk 1.2.27
i all, I have a problem with tomcat 6.0.18 Apache/2.2.9 mod_jk/1.2.27 Some times the content-type sent from my tomcat is ignored and the response have content type text/plain. For this reason some servlet that should return excel file and set the contentType(application/excel) have bad beahviour on the browser: the file was not recognized as excel but as binary generic file. The problem is present also for normal html page: some times the HTML source are displayed on the browser. I have found that mod_jk 1.26 was affected by this problem but the problem was fixed http://markmail.org/message/jk7ssoyhuadvjvh3 This is my configuration: #Load mod_jk module LoadModule jk_module modules/mod_jk.so #Where to find workers.properties JkWorkersFile conf/workers.properties #Where to put jk logs JkLogFile logs/mod_jk.log #Set the jk log level JkLogLevel debug # Select the log format JkLogStampFormat [%a %b %d %H:%M:%S %Y] #JkOptions indicate to send SSL KEY SIZE JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories +FlushHeader #JkRequestLogFormat set the request format #JkRequestLogFormat %w %V %T # Send /ROOT to worker named “myworker” #JkMount /* myworker Someone can help me ?

Re: bad content type mod_jk 1.2.27
Hi, .ic is the extension mapped to the controllers of my spring webapp. The Excel is generated by a controller (servlet): this controller execute this instructions response.setContentType(application/excel); response.setHeader(Content-Disposition,attachment; filename=\ nomeFileExcel \); response.flushBuffer(); For the Excel the problem is repetitive but also for other normal html page (generated by jsp) the text/plain content/type was returned with random frequency. If on apache I add AddType *.ic text/html all the html page are ok but the excel are printed with binary format on the browser. So AddType is not the correct solution: I need that the content type is the content type returned by tomcat.

Re: bad content type mod_jk 1.2.27
Hi, many thanks for advice: I have enabled this log and I see the information that I attach. http://www.nabble.com/file/p20903814/committed.txt committed.txt The problem seem to be the row FINE: Response already committed but I don't understand why the response was committed... I investigate on it.

Re: bad content type mod_jk 1.2.27
Hi, I have tested an other controller that return to a jsp with simple HTML. The last rows of this controller are ... log.debug(isCommitted?? +response.isCommitted()); Map m = new HashMap(); m.put(tutteListe, tutteListe); return new ModelAndView(getInputView(), m); I have invoked 5 times the same controller and the first 4 times the response is ok and the last call resulted on text/plain content type and in effect isCommitted return true. 2008-12-08 22:54:20,506 DEBUG [it.urlandus.events.app.web.controller.frontend.RegistrantsList] - isCommitted?? false 2008-12-08 22:54:25,104 DEBUG [it.urlandus.events.app.web.controller.frontend.RegistrantsList] - isCommitted?? false 2008-12-08 22:54:25,538 DEBUG [it.urlandus.events.app.web.controller.frontend.RegistrantsList] - isCommitted?? false 2008-12-08 22:54:27,240 DEBUG [it.urlandus.events.app.web.controller.frontend.RegistrantsList] - isCommitted?? false 2008-12-08 22:54:28,781 DEBUG [it.urlandus.events.app.web.controller.frontend.RegistrantsList] - isCommitted?? true Any idea about a possible cause of this issue?
