  • how to generate thread dump java on out of memory error

    - by Jigar
    does java 6 generate thread dump in addition to heap dump (java_pid14941.hprof) this is what happened to one of my applications. java.lang.OutOfMemoryError: GC overhead limit exceeded Dumping heap to java_pid14941.hprof ... I did find ava_pid14941.hprof in working directory, but didn't find any file which contains thread dump. I need to know what all the threads were doing when I got this OutOfMemory error. Is there any configuration option which will generate thread dump in addition to heap dump on out of memory exception?

  • Maven 2 assembly with dependencies: jar under scope "system" not included.

    - by YuppieNetworking
    Hello, I am using maven-assembly plugin to create a jar of my application, including its dependencies as follows: <assembly> <id>macosx</id> <formats> <format>tar.gz</format> <format>dir</format> </formats> <dependencySets> <dependencySet> <includes> <include>*:jar</include> </includes> <outputDirectory>lib</outputDirectory> </dependencySet> </dependencySets> </assembly> (I omitted some other stuff that is not related to the question) So far this has worked fine because it creates a lib directory with all dependencies. However, I recently added a new dependency whose scope is system, and it does not copy it to the lib output directory. i must be missing something basic here, so I call for help. The dependency that I just added is: <dependency> <groupId>sourceforge.jchart2d</groupId> <artifactId>jchart2d</artifactId> <version>3.1.0</version> <scope>system</scope> <systemPath>${project.basedir}/external/jchart2d-3.1.0.jar</systemPath> </dependency> The only way I was able to include this dependency was by adding the following to the assembly element: <files> <file> <source>external/jchart2d-3.1.0.jar</source> <outputDirectory>lib</outputDirectory> </file> </files> However, this forces me to change the pom and the assembly file whenever this jar is renamed, if ever. Also, it seems just wrong. I have tried with <scope>runtime</scope> in the dependencySets and <include>sourceforge.jchart2d:jchart2d</include> with no luck. So how do you include a system scoped jar to your assembly file in maven 2? Thanks a lot

  • Migrating svn repo with non-flat branch hierarchy to mercurial

    - by Assaf Lavie
    Is there a conversion utility from svn to hg that can deal with a branch hierarchy that's more complex than just a flat list of branches under /branches? My repository has a directory that looks (conceptually) like this: /branches /projectA /v1.x /v1.1 /v1.2 etc.. IOW I need a tool that can get a tree structure as input that represents the branch hierarchy, and migrate this into hg (could be flat in HG, don't really care).

  • Standalone XULRunner app not loading the Flash player plugin

    - by Rajeesh
    Hi, I have created a standalone XUL application, and I copied "NPSWF32.dll"(flash plugin dll) to the "plugins" folder under the browser. When I launch the application, flash content is not getting displayed. If I set the MOZ_PLUGIN_PATH to the "plugins" directory before launching the application, everything is working as expected. Could someone tell me, what I needs to do in order to load the flash plugin automatically from the "plugins" folder. Thanks, Rajeesh

  • Counting FLOPS/GFLOPS in program - CUDA

    - by msx
    Already finished my application which multiplies CRS matrix and vector (SpMV) and the only thing to do now is to count FLOPS my application did. In my opinion it's really hard to estimate number of floating point operation in case of sparse matrix - vector multiplication, because the number of multiplies in one row is really "jumpy" or fluent. I only tried to measure time using "cudaprof" ( available in ./CUDA/bin directory) - it works fine. Any sugestions and instruction pastes appreciated !

  • Asp.Net MVC missing style and defaults to logon page

    - by user279750
    I just setup an out of the box "W2K8 R2 Web" server and installed IIS 7 out of the box. Then I installed the .NET4 framework and ran "aspnet_regiis -i" command. I created a site using .NET 4.0 Integrated app pool. I created an MVC application using the default MVC project template, without modifying I compiled the project and deploy the files using (Publish) to the virtual directory. I can pull the site up, but the styles are missing from the page and for some reason it routing to the /Account/LogOn?ReturnUrl=/

  • How to build Lucene / Solr from source code in windows environment in order to add patches

    - by Simon
    I have successfully implemented Apache’s Solr for free text searching a database driven web site build for windows platforms using Visual Studio in c#. I am trying to get a version Solr working with field collapsing (which is not in the release version). There are patches available from apache and discussions on the web of people successfully doing this for the version I am using but my problem is cannot get the build to work. I am a c# coder on windows platforms so java development is new to me. I understand I need to get the correct source code (and revision) from SVN, add the appropriate patches, then build the war file to deploy to my system. I cannot seem to get the source to build and produce the deployment code including jar (and subsequent war) files. My system is: Windows 7 Ultimate for development Visual Studio 2010 for c# / javascript development MyEclipse 8.6 / Eclipse 3.5 for the java build from source Subecplise 1.6x SVN plugin to get the source from apache’s SVN Apache Solr 1.4.1 So far I have: Found the right patches for the function I need: https://issues.apache.org/jira/browse/SOLR-236 Specifically I need to patch: field_collapsing_1.1.0.patch HTTPS //issues.apache.org/jira/secure/attachment/12357681/field_collapsing_1.1.0.patch and SOLR-236-1_4_1.patch HTTPS //issues.apache.org/jira/secure/attachment/12448216/SOLR-236-1_4_1.patch I downloaded the Lucene trunk version from the day before the patch was released (revision 958303 from 28/6/10) via subeclipse into a java package in myeclipse from: HTTPS //svn.apache.org/repos/asf/lucene/dev/trunk (Solr is the web implementation of Lucene and is in the subfolder solr/) I can apply patches to the solr directory once it has downloaded but the parent Lucene project doesn’t build the war files, copy the jar or other files into the bin folder (it stays empty). The build process starts, but doesn’t do anything apart from creating the folders bin and src. I am building the whole Lucene project, which contains Solr. I have tried building the source without patching and the same happens. If I copy out the Solr directory into a new project, it runs the build and copies all the related files, tests, etc but fails with 4,500 errors and does not produce the jar files or war file, which I assume is because it can’t find the Lucene trunk files which it depends on. I have two interrelated problems 1) I can't get the Lucene downloaded trunk to build 2) The jar, war and associated files are not created Can anyone help with what I am missing to build the war file? I have spent 2 days to get this far as the help online is extremely patchy and I can’t find a walk though tutorial on building a java war file from source in a windows environment. Any help will be much appreciated. Simon

  • what do i need to do so that mod_wsgi will find libmysqlclient.16.dylib? (osx 10.7 with apache mod_wsgi)

    - by compound eye
    I am trying to run django on osx 10.7 (lion) with apache mod_wsgi and virtualenv. My site works if I use the django testing server: (baseline)otter:hello mathew$ python manage.py runserver but it doesn't work when I run apache. The core of the error seems to be Library not loaded: libmysqlclient.16.dylib I think its to do with the path apache is using to locate libmysqlclient.16.dylib when I run otool in the lib directory it looks good otter:lib mathew$ pwd /usr/local/mysql/lib otter:lib mathew$ otool -L libmysqlclient.16.dylib libmysqlclient.16.dylib: libmysqlclient.16.dylib (compatibility version 16.0.0, current version 16.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.0.1) but from outside it can't find it otter:lib mathew$ cd / otter:/ mathew$ otool -L libmysqlclient.16.dylib otool: can't open file: libmysqlclient.16.dylib (No such file or directory) if i manually set DYLD_LIBRARY_PATH otool works otter:lib mathew$ DYLD_LIBRARY_PATH=/usr/local/mysql/lib otter:lib mathew$ otool -L libmysqlclient.16.dylib libmysqlclient.16.dylib: libmysqlclient.16.dylib (compatibility version 16.0.0, current version 16.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.0.1) When I run the django testing server, my .bash_profile sets up the virtualenv and the path to the mysql dynamic library export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/:$DYLD_LIBRARY_PATH export PATH When i run apache it finds my virtualenv paths, but it doesn't seem to find the dynamic library path. I tried adding this path to /usr/sbin/envvars DYLD_LIBRARY_PATH="/usr/lib:/usr/local/mysql/lib:$DYLD_LIBRARY_PATH" export DYLD_LIBRARY_PATH and to /private/etc/paths.d/libmysql /usr/local/mysql/lib then restarted the machine but that has not changed the error message.

  • Help getting started with MEF

    - by SteveCl
    Hi, I was reading somewhere that with MEF I can simply drop a dll into a directory and my application (with some MEF magic) will be able to read it and execute the code in it? Hopefully only classes that implement an interface that I define?? Can someone help me to get going, with some links maybe for my problem. I've looked through some of the docs, but nothing seems to be what I'm after and its tricky when I don't know exactly what to search on... Thx S

  • Flash Player - green box with version number

    - by Gavin
    I'm trying to get a very simple Flash video working using SWFembed, and it does work across multiple computers at this point in multiple browsers, but as soon as I pushed it live I got this: http://cl.ly/1EDS I've adjusted file permissions, but it is exactly the same code and files as in another directory on the server. I've seen this a few times (green box with version number), but have not been able to find any reference to it online. Thanks for any suggestions in advance!

    I would like to reconfigure the StyleCop import path in my project file. Currently it looks like this: <Import Project="$(ProgramFiles)\MSBuild\Microsoft\StyleCop\v4.3\Microsoft.StyleCop.targets" /> I would like to include the Microsoft.StyleCop.targets file in my project directory, and thus do something like this: <Import Project="$(ProjectDir)\Microsoft.StyleCop.targets" /> Is something like this possible, if so what is the proper way to do it?

  • .NET 2.0 Process Elevation for App Installation

    - by Brian Gillespie
    We have an application written in both C++ and .NET that installs for all users in the Program Files folder. This application downloads new versions of itself (as MSI installers) and spawns the new installer process to replace itself. The install process as it exists today: Copy an install manager app (C#, .NET 2.0) to the temp directory. Call this 'Manager' Manager is executed with elevated privs per this article. The original application exits. Manager spawns the MSI installer (with elevated privs, since the copy is elevated) Manager spawns the new version of the app. The bug: The newly installed app is running in an elevated state. This causes problems I won't enumerate here. Ideally, the launch of the newly installed app would be run with the permissions of the original user. I can't figure out how to demote the app back to being the standard user after elevation. An inelegant hack: (yeah, yeah, this whole process is inelegant anyway) Copy the install manager to the temp directory Run the install manager with standard user privs. Lets call this instance 'LowlyManager'. Original application exits. LowlyManager spawns the app again, this time with elevated privs. Let's name this instance 'UpperManagement' UpperManagement spawns the installer UpperManagement exits gracefully, returning the exit code of the installer. LowlyManager interprets the error code from UpperManagement, and spawns the newly installed application. This time as the original invoker. Is there a better way to do this? (I've left out a bunch of other details before and after these steps that make the process smoother for the user, but this should be enough to understand the core of the problem I'm trying to solve.) Other requirements: We can't install as a per-user app The user shouldn't be presented with an authentication dialog box if UAC would have simply asked "are you sure you want to allow this?". I think this might kill a solution using WindowsImpersonationContext, but I'm not sure. The system needs to work on XP, Vista, and Windows 7 (even if there is a separate process for XP).

  • How do I run .class files on windows from command line?

    - by AndrejaKo
    Hi! I'm trying to run .class file from command line. It works when I manually move to the directory it's stored in, but when I try something like this: java C:\Peter\Michael\Lazarus\Main it says it can't find the main class. Is there any solution to this other than making a .jar file (I know that .jar is the best solution, but at this moment isn't the one I'm looking for)?

  • Java api to get windows Special folders

    - by SvrGuy
    I once found a nifty little library that used JNI to allow java applications on Windows to get the locations of various "special" directories on windows. I can't for the life of me find it again... In particular, I need to get the location of the "All Users" (shared) "Application Data" directory. So, anyone have a bullet proof way in Java to locate the "All Users" "Application Data" folder? It needs to be bullet proof.
