To check which are installed:
Code:
lslpp -l| grep -i java
  Java14.sdk                1.4.2.75  COMMITTED  Java SDK 32-bit
  Java5_64.sdk              5.0.0.50  COMMITTED  Java SDK 64-bit
  Java14.sdk                1.4.2.75  COMMITTED  Java SDK 32-bit
  Java5_64.sdk              5.0.0.50  COMMITTED  Java SDK 64-bit

rpm -qa| grep -i java

To check what is actually on your disk:
Code:
ls -la /usr| grep -i java
drwxr-xr-x   7 bin      bin            4096 Feb 09 2007  java14
drwxr-xr-x   7 bin      bin             256 May 17 2006  java5_64

To see what's in the path:
Code:
which java
/usr/java5_64/bin/java

To get it's version details:
Code:
java -version
java version "1.5.0"
Java(TM) 2 Runtime Environment, Standard Edition (build pap64dev-20060511 (SR2))
IBM J9 VM (build 2.3, J2RE 1.5.0 IBM J9 2.3 AIX ppc64-64 j9vmap6423-20060504 (JIT enabled)
J9VM - 20060501_06428_BHdSMr
JIT  - 20060428_1800_r8
GC   - 20060501_AA)
JCL  - 20060511a


Usually start the executable with something like "-version" to get some info.
