Re: Tomcat 7 applet session problem
It could be caused by the useHttpOnly attribute of the context to prevent cross-site scripting attacks. HttpOnly cookies are not allowed to be passed to any client side script or Plug-in - such as a java applet. see e.g. http://tomcat.apache.org/tomcat-6.0-doc/config/context.html#Common_Attributes So you have to a) disable httpOnly cookies b) pass a parameter into the applet with the sessionId and the applet has to use this sessionId in the requests.

The problem is the session between the web application and the applet varies which runs in the same browser tab. Dont know why in tomcat 7 the applet request was considered as separate session but instead in tomcat 6 bot are considered as same session request. Is there any configuration changes for it? Tomcat 7.0.x and later versions of 6.0.x change the session id after authentication*. You can't rely on the session id remaining the same, the applet will need to check for session id changes in the cookie (or url). p * In order to prevent some session hijacking attacks
Re: mod_jk restarting during uploads of large files
Yeh, I've worked out what was happening, seems that tomcat was being killed by the system running out of memory, which was happening without any log messages on the system at all, which was rather unhelpful and left me completely stumped for a while. However adding extra swap space and memory seem to fix the problem. Thanks anyway for the reply Quoting Rainer Jung rainer.j...@kippdata.de: It seems it is not a mod_jk problem. mod_jk never shuts down Tomcat, but obviously your Tomcat shuts down during processing the request. I would - update Tomcat *and* the service wrapper (jdvc) to the most recent patch update (e.g. Tomcat 5.5.33). - run Tomcat once without the service wrapper to decide, whether the problem comes from the wrapper or from Tomcat respectively your web application.

TOMCAT 64bit 32BIT differences - URGENT
Hi All, apologies if this question has been asked before. I need to know the main differences between 64 32bit tomcat for windows. Is the tomcat.exe and all associated files in the bin folder and lib folder trully compiled 64bit or is the installer solely 64bit for installing onto 64bit OS? and the tomcat just uses which ever java you have installed to create its jvm? i have been asked to change a set of servers from 32bit to 64bit for tomcat and java if it turns out that the java is the only thing i need ot change it will save me tons of work if the tomcat needs to be installed that nots a biggy as i can copy and paste the tomcat folder into the place of the existing and put back the conf and webapps folder so in theory this will allow me to work as if nothing changed you answers on the 32-64bit is greatly appreciated!!

URI served from cache
Hi there,
My question is simple : is it possible to disable the cache of Tomcat ?
I think I've browsed the entire web about that without finding my answer.
As I'm developping a website under Eclipse, I would like to see modifications
as they are developped but here, when I change an image, for example, it's
always given from the Tomcat's cache : I can see, in the Console of Tomcat, for
each page I request, about 20 messages like this one :
{date and hour} DEBUG [http-8080-1] lutece.cache - URI served from cache :
/PSP/images/logo.png
If I modifiy the logo.png, I can't see the new one in my browser, even if I
stop and restart Tomcat, even if I disable my browser's cache...
I'm using Tomcat 6.0.26 on Windows XP SP3.
Thanks by advance for any way of answer.

What is 'lutece.cache'? That's not a log message Tomcat would output.

Are you sure that the file is actually being updated?
If you're stopping and starting Tomcat then you are terminating the
cache (which is in-memory), so it will pick up the new version.
Assuming you're using Tomcat's cache and not a third party one.

Re: TOMCAT 64bit 32BIT differences - URGENT
2011/7/7 saj-khan saraj.k...@gmail.com: Hi All, apologies if this question has been asked before. I need to know the main differences between 64 32bit tomcat for windows. Is the tomcat.exe and all associated files in the bin folder and lib folder trully compiled 64bit If you compare content of *-windows-arch.zip files, you should note that only two files differ between each of them: tomcat7.exe - service runner tcnative-1.dll - Tomcat-Native (optional component, can be deleted) They are loaded in the same process as JVM and thus have to use the same CPU architecture. Service configuration application (tomcat7w.exe) is 32-bit. The rest of code is neutral to CPU architecture. or is the installer solely 64bit for installing onto 64bit OS? and the tomcat just uses which ever java you have installed to create its jvm? On a 64-bit system you can install either 32-bit version or 64-bit one -- use the same as the version of Java that you installed. Recent versions of Tomcat (more recent that ~6 months ago -- see change log for details! ) have all three versions of (tomcat7.exe tcnative-1.dll) packed within installer and will autoselect the one that matches the JRE. You select the JRE during installation. i have been asked to change a set of servers from 32bit to 64bit for tomcat and java if it turns out that the java is the only thing i need ot change it will save me tons of work if the tomcat needs to be installed that nots a biggy as i can copy and paste the tomcat folder into the place of the existing and put back the conf and webapps folder so in theory this will allow me to work as if nothing changed you answers on the 32-64bit is greatly appreciated!! - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: mod_jk restarting during uploads of large files
Hi. Since this concerns large files upload, I wonder if something along these lines is happening : A file upload is a POST request, usually with an enctype=multipart/form-data format (similar to an email with attachments). Furthermore, for sending this file, the browser is going to encode the file using Base64 encoding, which increases the brutto size by at least 1/3. So your 500 MB file becomes something like 700 MB in the POST. Now let's imagine that by default Tomcat is buffering this in memory until it has read the whole POST and can start parsing it. That could easily cause some memory issues. I seem to remember that there existed a parameter somewhere telling Tomcat how much it should buffer in memory before it starts offloading that to disk, but I do not remember where.

Re: mod_jk restarting during uploads of large files
André, I believe the file upload you are talking about is the FileUpload project from the Apache Commons: http://commons.apache.org/fileupload/ This does indeed have a disk-based implementation of an upload file. The package is org.apache.commons.fileupload.disk and it implements the project's org.apache.commons.fileupload.FileItem interface. Y'all can check the JavaDoc for DiskFileItem and DiskFileItemFactory. There are some good, out-of-the-box-ready examples, too. Suffice it to say that DiskFileItemFactory.DEFAULT_SIZE_THRESHOLD--The default threshold above which uploads will be stored on disk.--is 10K. I'm using FileUpload v1.2.1 and it has worked flawlessly, both as is or with a FileCleaningTracker from the Commons I/O project. We've tested it with files a couple hundred bytes to over an MB, and it's worked fine on Linux, Sun, MacOS, and Windows, with and without mod_jk, with and without SSL.

RE: NPE at StandardWrapperValve.invoke() in Tomcat 7.0.16
Maybe I can reproduce the
NPE if I make a servlet that takes a long time to finish the request,
to see what was the original exception that has been suppressed by the
NPE.
OK, I was able to reproduce a NPE in TC 7.0.16 with a Servlet that calls
Thread.sleep(2), then make a request to that servlet and immediately
redeploy that webapp. However, this time the NPE was not in
StandardWrapperValve.invoke(), but in StandardContextValve.invoke():

The lines around 172 in StandardContextValve are these:
166 // If the request was async at the start and an error occurred then
167 // the async error handling will kick-in and that will fire the
168 // request destroyed event *after* the error handling has taken
169 // place
170 if (!(request.isAsync() || (asyncAtStart request.getAttribute(
171 RequestDispatcher.ERROR_EXCEPTION) != null))) {
172 context.fireRequestDestroyEvent(request);
173 }
The problem here is that context is null (I debugged TC in Eclipse). However,
this time it seems that it is not another Exception that has been suppressed by
a NPE.
I checked that the NPE in StandardContextValve.invoke() also occurs in Tomcat
7.0.18.
Unfortunately, I was not able to reproduce the NPE in
StandardWrapperValve.invoke().

Konstantin Preißer
