The reason is, that older Weblogic Versions use the Java VM "JRockit" http://www.oracle.com/technetwork/middleware/jrockit/overview/index.html

The JRockit VM is no longer supported in Java 7 or higher.

All of the other solutions here seem to be hacks and none of them helped me. I had the same Problem with a Weblogic 10.3.5 and I found out, the installation was incorrect.

The Problem is, that there is no java version check in the installer, so if you don't know that you can't use Java 7 or higher you are screwed.

These steps fixed it for me:

  • You need to make sure you have Java 6 or lower installed.
  • Reinstall the Weblogic and make sure to specify the correct JDK

In OSX, look for the this folder /Users/{USERNAME}/.jdeveloper/system{VERSION}/DefaultDomain/bin

Edit the file setDomainEnv.sh and look for SUN_JAVA_HOME and make sure the value is the same value as your JAVA_HOME, i.e. /Library/Java/JavaVirtualMachines/jdk${JDK_VERSION}.jdk/Contents/Home, by default it seems it is set to an empty string "".

Edit the file startWebLogic.sh and add the following before setDomainEnv.sh is called.

JAVA_VENDOR=Sun

You can test it out by running sh ./startWebLogic.sh, if it runs with -jrockit error, then all is good :)

I've also tested with Java JDK 1.7 and it seems to work.

Jdeveloper 11g do not support jdk 1.7

https://forums.oracle.com/thread/2482850

I fixed it by add to top of c:\users{user}\AppData\Roaming\JDeveloper\system{version}\DefaultDomain\bin\setDomainEnv.cmd:

set SUN_JAVA_HOME=E:\Oracle\Java\jdk1.6.0_37
set JAVA_VENDOR=Sun

Try modifying the startWebLogic.cmd file (WIN7)

c:\users\{user}\AppData\Roaming\JDeveloper\system{version}\DefaultDomain\bin\startWebLogic.cmd

to contain 

set JAVA_VM=-server
set MEM_ARGS=-Xms512m -Xmx1024m -XX:MaxPermSize=512m
