Hi,

I have WAS 5.1, which means that by default it uses java (jre) 1.3.
A collegue has mentioned it's possible to make WAS it use java 1.4 . He also recommended to use *IBM's* implementation of jre 1.4.

I've tried searching the ibm website, but I must be doing something wrong because I can't seem to find the IBM 1.4 implementation, nor any instructions on how to integrate it with was 5.1...
Could anyone kindly refer me to the relevant links ?

thanks very much !

Are you sure about that? I think the default JRE for WAS 5.1 is 1.4.1. WAS 5.1.1 upgrades to JRE 1.4.2. Check by executing $WAS_HOME/java/bin/java -version.
WebSphere ships with an IBM JDK that MUST be used. Upgrade the JDK by applying the appropriate fixpack(s). For example, to upgrade the JDK from 1.4.1 to 1.4.2, apply fixpack1. You don't normally just get an IBM JDK and install it. WebSphere libraries are very dependent on the JDK.

I'm not aware of a public website to down the IBM JDK only.

Sol,
Bill is correct that WAS uses 1.4 by default. Did you mean WSAD 5.1 by chance?

I'm using WSAD 5.1.1 and it only gives me 1.2 and 1.3. I've tried changing the Installed JREs to point to jre1.5.0_04 and done any Software Updates but I still don't have any J2EEs to choose from other than 1.2 or 1.3.

Any suggestions?

EDIT: Never mind, I figured it out. I needed to go to the project's Java Compiler properties and Configure Workspace Settings and under Compliance and Classfiles set the Compiler compliance level to 1.4.
