How do I specify the version of JDK WebSphere uses? When you do a typical installation, WebSphere uses IBM JDK, but if I want to change it to Sun's JDK afterwards, how do I do it?
I am using IBM WebSphere Application Server 3.5.0.
Thanks.

I think you can't.
Using WebSphere (3.x or 4.x) forces you to use IBM JDK.
Please let me know if I'm wrong.

Hi guys,
You can use other JDK and we are using JDK1.3 from sun.
This is a paragraph from info center:
In the Installation Options dialog, select Custom Installation; then click Next.
In the Choose Application Server Components dialog, select those components you want and deselect those components you do not want. You will likely want to include the default options.
Clicking Other JDK displays the Select Java Development Kit dialog. If you have a non-IBM Java development kit installed, we recommend that you specify that you want the Java Development Kit (IBM Developer Kit 1.3.0.). Also specify the destination directory for the IBM Developer Kit. Further, to use the IBM Developer Kit, you must remove your other JDKs from the jre\lib\ext directory. If you use a JDK other than IBM Developer Kit to run WebSphere Application Server, it must be at the XML4j/Xerces 3.1.1 level. Finally, click Next. Otherwise, click Back to exit the dialog.
Go to info center for more info.

Also EJB Java client is not limited to IBM JDK. Check out the document from info center. However, you need client side plug-in.

MMM... I got another question....
I'm using WebSphere 4 and I need to use the newest sdk version for it. I already installed and I wish to change only the version in the websphere application developer.
I think this is possible, like it used to be an easy way with JBuilder.
Where o how can I change the SDK (JDK) version???
Thanks
