If you create a wrong link, you can delete it using file explorer or rmdir command.Error: Unable to Launch the Java Virtual Machine - OA Framework I am trying to configure my PC for OAF customization, while launching Jdev getting following error "Unable to Launch the Java Virtual Machine Located at path.
Mklink /j "d:\devTool\eclipse\jre" "C:\Program Files\Java\jdk1.8.0"īTW, delete directory junction will NOT delete any file. The command for creating the jre folder will be:
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). 64 bit problem for both Eclipse and Java. 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 appears, IIRC.Īs many folks already alluded to, this is a 32 vs. And since it had been a while since I had set it up, I could not remember its version either.)
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. 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.Īdding 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.) 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. I cleaned up the mess, deinstalled all current Java's, installed only JDK + JRE 1.7 64-bit.
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. Judging from the PATH variables, some installations were completely useless, since they were never used. 64-bit OS | 64-bit JDK | 64bit Eclipse ( 64-bit only)Įach of them had their own entry in the PATH variable, all was working more or less.64-bit OS | 32-bit JDK | 32-bit Eclipse.32-bit OS | 32-bit JDK | 32-bit Eclipse ( 32-bit only).
