Java Setup on Scientific Linux showing two diffent versions

Question

Java Setup on Scientific Linux showing two diffent versions.

I am trying to get java setup right on Scientific Linux.

If I do a javac -version I get the following: java_1.7.0_10 which is the version that I really want to be using.

But if I do a java -version I get the following:

OpenJDK Runtime Environment (IcedTea6 1.11.5) (rhel-1.50.1.11.5.el6_3-x86_64)
OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)**

Which is not the version I would like to run with... Can someone please tell me how to fix this issue.. thanks

Answer 1

use this to choose java alternative if you have already installed.

  /usr/sbin/alternatives --config java

Answer 2

You should check your $PATH enviroment-variable.

Type which javac to see where the javac-binary is located.

For example:

which javac -> /usr/local/bin/javac

then execute:

export PATH=/usr/local/bin/:$PATH

Could you post please the output from:

which java && which javac

update-alternatives --list java
