Author How to get JVM version under WebSphere?

2006-10-28, 1:41 pm

Hi,

I have a Sun Java runtime JDK1.5.0_04.

How can we find out for sure which JVM version is being used by WAS 6.0 ? I am trying to install some JAI libs from:

http://java.sun.com/products/java-m...d-1_1_2_01.html

http://javashoplm.sun.com/ECom/docs...rtDetailId=jaii o-1.0_01-oth-JPR&SiteId=JSC&TransactionId=noreg

which i successfully installed. However, when i am running my application, it is giving me a class not found error message which points out that WAS is not picking up the jar files. Im not sure if Websphere is using that jdk?

How do i check this and bring the changes?

cheers,

Adit

If you're running WAS 6.0 then you won't be using a 1.5 JDK and it
certainly won't be Sun unless you're running on Solaris.

WAS has it's own JDK inside.
For WAS 6.0 JDK version is 1.4.2.
If you want to use JDK version 1.5.0, you have to install WAS 6.1.

Current WAS JDK Level you can view, if you run "java -version" from
$(was.install.root)\java\bin

For example:

C:\Program Files\IBM\WebSphere\AppServer\java\bin>java -version
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2)
Classic VM (build 1.4.2, J2RE 1.4.2 IBM Windows 32 build cn142-20060421 (SR5) (J
IT enabled: jitc))
