On Linux, once you installed JDK provided on edelivery for Peopletools 8.54 (jdk-7u55-linux-x64.rpm), you make a go for Weblogic.
Here you go:
java -jar wls_121200.jar
On Oracle Linux 7, it ends quickly by the following error :
OpenJDK JVM not supported on this platform.
Also tried with 7u65, no luck. To solve it, install the JDK 7u67 – the latest available. You can download it here :
Weblogic install should run now - do not forget to set JAVA_HOME before hands.
There’s a warning though about unsupported platform (Oracle Linux 7 is not yet), but it does not hurt.
