HowTo place Manager-App
Hello, What´s the best place to make access to the manager-app? 1. Place a separate context for Manager in the Host-Tag in the server.xml 2. Place the manager.xml in the /conf/Catalina/[Hostname]/ path? Best regards Alexander smime.p7s Description: S/MIME cryptographic signature

If the CPU usage is not high during page generation over SSL, and the network isn't inducing delays, then the threads must be waiting for something. Can you take some thread dumps during the delay period and find out what they're stuck on? (My suspicion is reads from /dev/random, but I thought that was only during Tomcat initialization.) Really I don't know what to search for there (maybe you could give me some clues?). Could you explain why reading from /dev/random possibly could be the case here? I thought that seperate SSL Handshake could be made for each of the requests, but I can't see such behaviour in the dumps. Only one or zero threads commiting a handshake, others appear to autoaccept it (maybe not a precise term). Also, is Tomcat front-ended by anything (e.g., httpd), or are you accessing it directly? No, it isn't. Did anything else change when you upgraded Tomcat? For example, the JVM version? No, nothing changed.

You can unzip it in a new directory, or right over the one that's there. (You may want to save the contents of your conf sub-directory, and restore them after the unzip). Then you should be able to navigate to the bin directory and start tomcat in the command window (with startup.bat), without involving the tomcat6.exe.

I also believe that it is unlikely that the same exact RAM addresses are being used in your various tests, so this would also tend to reduce the possibility of a hardware-related issue. So far thus, it seems to point to either a problem in the JVM itself, or in something which you particular setup is making the JVM do. So let's try to change the JVM. It should be possible, even under a 64-bit Windows, to install a 32-bit JVM, no ? (and Tomcat will run the same as long as you do not use exotic Heap size values). Install it at a different location than your current one, change the JAVA_HOME or JRE_HOME in your setenv.bat to point to this new JVM, and re-run the same test. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Hello all, im facing an issue, ive been testing for a while different approaches without success. I have a servlet that basically does . creates an image . store the image on disk . returns an html img tag pointing to the stored image. reason why the servlet doesnt returns the image directly using a response type image/png is the servlet is called from an ajax script, this ajax script renders the inner text inside a div on a jsp page on the same context that the server runs. ajax can only render html on divs, there's no way to return binary content (the image) from the servlet to the ajax script. So, i have to create the image on the servlet (done) , store the image on the disk (done), and return the img tab also done. Thing is, where im able to store the image from the servlet im not able to read it from the jsp. I tried with /tmp, i tried with servletcontext.getpath to store the file on that dir, nothing seems to work. where should i store and reference those images to be written by the servlet and read by the jsp? thanks in advance - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Then you should be able to navigate to the bin directory and start tomcat in the command window (with startup.bat), without involving the tomcat6.exe.

RE: storing images
From: alexis [mailto:alz...@gmail.com] Subject: storing images So, i have to create the image on the servlet (done) , store the image on the disk (done), and return the img tab also done. Thing is, where im able to store the image from the servlet im not able to read it from the jsp. As David suggests, java.io.tmpdir is probably a bit safer than /tmp, since you have some control over that and it can be isolated from other programs running on the same box. The real problem is how to retrieve the images once stored. Tomcat normally uses its built-in DefaultServlet to deliver static content, but that only works with files stored within a given webapp (and you should never write into a webapp's deployment directory). You have a couple of options: 1) Create a dummy webapp whose sole purpose is to provide a location for the dynamically generated images. Create some directory outside of Tomcat's file structure to hold the images, and place a Context element in conf/Catalina/[host]/[dummyAppName].xml with a docBase attribute (and nothing else) that points to that directory. The img tags should refer to [dummyAppName] as the URL for retrieving the images. - or - 2) Create a subclass of DefaultServlet that knows where you put the images, and direct image references to it via the appropriate servlet-mapping in your WEB-INF/web.xml file. Not sure which methods of the DefaultServlet you'll have to override. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Look to see what the threads are doing. Some will be waiting on monitors, some might actually be doing work, some might be stuck on I/O requests. You have to look at each call stack to see (a laborious process, unfortunately). It's often useful to take several thread dumps a few seconds apart and see what's changing and what isn't. Could you explain why reading from /dev/random possibly could be the case here? Because /dev/random (unlike /dev/urandom) can wait an arbitrarily long time to gather enough randomness before returning data. This is especially problematic on virtual machines running as servers, which have very little going on to generate entropy. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: Tomcat 6.0.32 on 64-bit 2008 server - Event 1000, Application Error
After some waiting with Tomcat still down, I tried startup.bat again, and so far I'm not getting any errors. I've been starting and stopping Tomcat with the .bat scripts, and can't seem to get it to break. Time has been my enemy the past few days with this, so I'm expecting it to break at some point. I'll keep an eye on it for now and see what happens, and will report back. Andre and others: Thank you for all your help so far - hopefully some solid information will appear as to why this is happening... So far thus, it seems to point to either a problem in the JVM itself, or in something which you particular setup is making the JVM do. So let's try to change the JVM. It should be possible, even under a 64-bit Windows, to install a 32-bit JVM, no ? (and Tomcat will run the same as long as you do not use exotic Heap size values).

Preventing or recovering from SocketException: Interrupted system call
I'm using Tomcat 5.5 to host a webapp that we deploy on Windows, Linux, and OS X. The webapp includes a Java Native Library. Right now we're seeing a scenario only on Mac OS X where Tomcat shuts down with this message: SEVERE: StandardServer.await: accept: java.net.SocketException: Interrupted system call at java.net.PlainSocketImpl.socketAccept(Native Method) at java.net.PlainSocketImpl.accept(PlainSocketImpl.java:402) at java.net.ServerSocket.implAccept(ServerSocket.java:450) at java.net.ServerSocket.accept(ServerSocket.java:421) at org.apache.catalina.core.StandardServer.await(StandardServer.java:379) The user scenario that reproduces this is one where we're pretty sure system signals are being fired, which could account for why the system call is interrupted. This has been seen with Java 1.5 on OS X 10.5.8 and Java 1.6.0_24 on OS X 10.6.7. My question to the list is whether it will work to modify StandardServer.java to ignore the exception and continue on. My understanding is the interrupted system call isn't actually fatal.

Re: storing images
What i did (im testing and profiling it) is. As the images are around 10/12 and each image has around 30 to 35k. Im storing the images as servletcontext attribute. So calling to the servlet with ?code=1 builds and stores image1 on servlet context. And returns html with img src=servlet?get=1 So ajax sends that to the jsp that calls servlet?get and that returns the image. It's working now, what im profiling is to verify no matter how many users are requesting images, image1 is the same for every user and if one user builds up the image again, all others gets the new one. As those images are stored on servletcontext, all are shared among the webapp so images are not duplicated or triplicated or n-cated. I dont know if it's a good solution, but up to know it's working and really fast.
