Failed to load the JNI shared Library JDK

Question

When I try opening Eclipse  a pop-up dialog states      Failed to load the JNI shared library  C  JDK bin client jvm dll      Following this  Eclipse force closes   Here s a few points I d like to make      I checked to see if anything exists at that path  It does exist    My Eclipse and Java SE Development Kit are both 64-bit  I checked my system  and it can handle 64-bit    I ve searched for this problem on Google and on Stack nbsp Overflow  and the only answer I found was to download the 32-bit versions of JDK and Eclipse    Downloading the 32-bit versions is something I only want to do as a very last resort  What would be suggested to solve this issue

Make sure you are starting Eclipse with Administrator rights

As many folks already alluded to  this is a 32 vs  64 bit problem for both Eclipse and Java  You cannot mix up 32 and 64 bit  Since Eclipse doesn t use JAVA HOME  you ll likely have to alter your PATH prior to launching Eclipse to ensure you are using not only the appropriate version of Java  but also if 32 or 64 bit  or modify the INI file as Jayath noted      If you are installing Eclipse from a company-share  you should ensure you can tell which Eclipse version you are unzipping  and unzip to the appropriate Program Files directory to help keep track of which is which  then change the PATH  either permanently via  Windows  Control Panel -  System or set PATH  path to 32 or 64bit java bin  PATH   maybe create a batch file if you don t want to set it in your system and or user environment variables   Remember  32-bit is in Program files  x86    If unsure  just launch Eclipse  if you get the error  change your PATH to the other  bit  version of Java  and then try again  Then move the Eclipse directory to the appropriate Program Files directory

Make sure your eclipse ini file includes the following lines   -vm C  path to 64bit java bin javaw exe   My eclipse ini for example   -startup plugins org eclipse equinox launcher 1 1 1 R36x v20101122 1400 jar --launcher library plugins org eclipse equinox launcher win32 win32 x86 64 1 1 2 R36x v20101222 -product org eclipse epp package java product --launcher defaultAction openFile --launcher XXMaxPermSize 256M -showsplash org eclipse platform -vm C  Program Files Java jdk1 6 0 32 bin javaw exe --launcher XXMaxPermSize 256m --launcher defaultAction openFile -vmargs -Dosgi requiredJavaVersion 1 5 -Xms40m -Xmx512m   Use OS and Eclipse both 64 bit or both 32 bit keep same and config eclipse ini   Your eclipse ini file can be found in your eclipse folder

In my case  I tried to launch java from the command prompt and got this error     Error  could not open  C  Windows jre lib amd64 jvm cfg    It meant  java  was looked for in the PATH starting at this wrong directory  Deleting the folder C  Windows jre  solved the issue

If you use whole 64-bit trio and it still doesn t work  I ve come to this problem while launching Android Monitor in Intellij Idea   probably wrong jvm dll is being used opposed to what your java expects  Just follow these steps    Find the jvm dll in your JRE directory  C  Program Files Java jre7 server bin jvm dll Find the jvm dll in your JDK directory  c  Program Files Java jdk1 7 0 xx jre bin server  Copy the jvm dll from JRE drectory into your JDK directory and overwrite the jvm dll in JDK    Don t forget to make a backup  just in case  No need to install or uninstall anything related to Java

One of the easy ways to resolve it is to copy the jre folder from installed the JDK into the Eclipse installation folder  Make sure that JDK you copy from is the same architecture as your Eclipse installation   I had to configure my machine that way  because I run both Eclipse and Appcelerator Titanium Studio on my machine  The Studio needs 32-bit Java  while Eclipse needs 64-bit

Just check the PATH environment variable  In My Computer -   Properties -  Advanced System settings -  Environment Variables -   left upper window  User Variables for  some name of PC     just check the PATH variable  If it doesn t exist create it with the following --   C  Program Files  x86  Java jre7 bin  lt --  I was faced with the same problem after had updated my Eclipse  I ve found that the path asked 64-bit version  but I had the 32-bit in dif path  It was helpful for me  P S   I have a 64-bit OS  32-bit JRE and 32-bit Eclipse  All works fine

The answers above me got me tempted so much  that I decided to dry run all the possible combinations with OS  Eclipse and JVM trio  Anyway  whoever is digging down and reading my post  check the following as a hot spot  I am Windows nbsp 7 user     You understand Program Files and Program File  x86  are two different folders    x86 stands for the 32-bit version of programs and the former is the 64-bit version  If you have multiple versions of Java installed with different bitness and release versions  which is bound to happen with so many open source IDEs  managers  administrative consoles  the best option is to set the VM argument directly in the eclipse ini file  If you don t  Eclipse will go crazy and try searching itself which is not good

User · Answer

Yes  just make sure your versions of Eclipse and JDK are both 64-bit  Just to make sure everything is correct uninstalled JDK and install it in Program Files and not in Program Files  x86   At least that resolved my problem

Thank you misterfrb  I realised that Eclipse was giving this error  because I had just installed Oracle 10g Developer suite  and it was looking for the jvm dll file in the C  DevSuiteHome 1 folder  I must have opted to install JDK again along with developer suite     After removing the DevSuiteHome lines from the paths variable and adding the correction location for 64-bit jvm dll  not sure if this was necessary  didn t try without   Eclipse worked again  and Developer suite still does too

I m not sure why but I had the jre installed into my c  windows directory and java exe and javaw exe inside my windows system32 directory   Obviously these directories were getting priority even AFTER adding the -vm flag to my eclipse ini file   Delete them from here fixed the issue for me

I want to previde another solution for this error  especially for who want to use 32-bit and 64-bit Eclipse in one system   Eclipse will startup using the JRE JDK in jre sub-directory if it exists   STS or other eclipse based IDE also support this feature      The solution is create directory junction using mklink exe command which exist in windows vista or newer version  junction exe offer similar function for Windows 2000 XP  Open the command line windows and exeute following command      mklink  j   ECLIPSE-HOME jre    JDK or JRE home    Of course  if the Eclipse is for 64-bit Windows  the architecture of JDK JRE must be the same   Assume    Eclipse for windows x86 64 is installed in d  devTool eclipse JDK for windows x64 is installed in C  Program Files Java jdk1 8 0   The command for creating the jre folder will be      mklink  j  d  devTool eclipse jre   C  Program Files Java jdk1 8 0    BTW  delete directory junction will NOT delete any file  If you create a wrong link  you can delete it using file explorer or rmdir command      rmdir  d  devTool eclipse jre

For a missing jvm dll file  we can provide the path of the dll file in eclipse ini file as  -vm C  Progra 1 Java jdk1 6 0 38 jre bin server jvm dll   Here it is important to remove any space in the path and the double quotes  It worked for me when i removed the quotes and space   I hope it helps someone

And for PDT users - avoid the Zend download page - it doesn t have any 64-bit downloads linked   Use the Elipse site itself   The above link had an older 3 6 Eclipse which then failed to update itself due to Eclipse Bug  317785   My solution was to just install 32-bit Java alongside 64-bit - this allowed the Zend installer to work   It s depressing that amount of Java   Eclipse cruft one has to go through to get a PHP IDE

Working pairings of OS  JDK and Eclipse      32-bit OS   32-bit JDK   32-bit Eclipse  32-bit only  64-bit OS   32-bit JDK    32-bit Eclipse  64-bit OS    64-bit JDK   64bit  Eclipse  64-bit only      I had several JDKs and JREs installed   Each of them had their own entry in the PATH variable  all was working more or less   Judging from the PATH variables  some installations were completely useless  since they were never used  Of course  the  inactive  Javas could be referenced manually from within Eclipse if I needed  but I never did that  so I really did not need them   At least I thought so at that time      I cleaned up the mess  deinstalled all current Java s  installed only JDK   JRE 1 7 64-bit    One of the Eclipse  installations  failed afterwards with the Failed to Load the JNI shared Library and a given path relative to the fresh installed JDK where it thought the jvm dll to be   The failing Eclipse was the only one of all my IDEs that was still a 32-bit version on my otherwise all-64-bit setup   Adding VM arguments  like so often mentioned  in the eclipse ini was no use in my case  because I had only the wrong JDK JRE to relate to    I was also unable to find out how to check if this Eclipse was a 32-bit or 64-bit version  I could not look it up in the Task Manager  since this Eclipse  installation  would not start up  And since it had been a while since I had set it up  I could not remember its version either    In case you use a newer JDK and a older JRE you might be in for trouble  too  but then it is more likely a java lang UnsupportedClassVersionError appears  IIRC

User · Answer

This happens because of the way the windows paths interact   Your 32-bit JRE is listed BEFORE your 64-bit version   Since javaw exe is named the same for both 32 and 64 bit versions  it tries the first one it finds   Change the order in your Path Environmental variables  so the 64-bit version higher on the list than the 32-bit  and it will work correctly

You can solve that problem as many other replicated  You need that Eclipse and the JDK be 32-bits or both on 64-bits  The architecture of the OS doesn t matter while the others remains on the same type of arquitecture

I have multiple versions of Java installed  both Sun JDK  amp  JRockit  both 32 bit and 64-bit  etc  and ran into this problem with a fresh install of 64-bit Eclipse for Java EE  JUNO     What did NOT work   64-bit trio as suggested by Peter Rader    I m using 64-bit Eclipse on 64-bit OS  Windows 7     I ensured Sun JDK 7 64-bit was the default java version   When I typed  java -version  from command line  cmd exe   Sun JDK 7 64-bit was returned     java version  1 7 0  Java TM  SE Runtime Environment  build 1 7 0-b147  Java HotSpot TM  64-Bit Server VM  build 21 0-b17  mixed mode    This did not resolve the problem for me   What DID work   Adding -vm option to eclipse ini as suggested by Jayesh Kavathiya    I added the following to eclipse ini   -vm C  apps java jdk7-64bit bin javaw exe   Note   I did not have to uninstall any of the various versions of JDK or JRE I have on my machine

User · Answer

This error means that the architecture of Eclipse does not match the architecture of the Java runtime  i e  if one is 32-bit the other must be the same  and not 64-bit   The most reliable fix is to specify the JVM location in eclipse ini   -vm C  Program Files  x86  Java jdk1 7 0 55 bin javaw exe   Important  These two lines must come before -vmargs  Do not use quotes  spaces are allowed

I had a similar problem  It was solved doing the following    Move Eclipse to Program Files  not to Program Files  x86    Remove the path to the 32-bit version of Java from the  path  environment variable    I have both versions of Java installed  but Eclipse kept trying to use the 32-bit one

Alternatively  get the same  bit  version of JRE and Eclipse and then create a new shortcut with the below target  replace the installed JRE and Eclipse location path     C  studio eclipse exe  -vm  C  Program Files Java jre7 bin server jvm dll  eclipse vm  C  Program Files Java jre7 bin server jvm dll  java home  C  Program Files Java jre7  java runtime version 1 7 0   That should do the trick
