Installation the Java Runtime Environment (JRE) on Red Hat Enterprise Linux

467 Views

Hi gurus,

I´m trying to install an ECC 6.0 SR3 (ABAP) on RHEL v.5 with Oracle DB.

But as I am newbie I have some doubts, in this point is with the Java Version JRE that is required in sap installion process.

I already installed the JRE through RPM Package File (I followed the instructions/steps described in this url - http://java.sun.com/j2se/1.4.2/jre/install-linux.html ) and I don´t have any problem... by the way I installed the JRE version 1.4.2_25 b02.

But after the installation I had a question, how do I check if the package was installed correctly? I insert the commad java -version, and the result was this:

java version "1.4.2"

gij (GNU libgcj) version 4.1.2 20080704 (Red Hat 4.1.2-46)

With this information I really do not know if the version 25 was installed...

I already check if there is some directory with the new file, and actually there exist in the directory /usr/java but this is not tell me if this is the new one!!

It´s possible to know which one is installed with other command by terminal?
