Where can I find a particular version of IBM JDK / JRE for Windows?

I'm trying to get a rather JDK-sensitive piece of Oracle software working with Websphere, and I need to find some particular versions of the IBM JDK to try. The problem is that IBM doesn't really make these readily available like Sun/Oracle does with theirs, and all the versions I've been able to get my hands on haven't worked for one reason or another.

Specifically, I need one of:
IBM Java 5 SR9 for Windows (ideal)
IBM Java 5 SR2 for Windows
IBM Java 5 SR10 for Windows

How could I get these directly from IBM? My company has a support contract for Websphere, and I hopefully could have one of our Websphere engineers download it if I can tell them where to go.

If there's no direct download, what are some good free products with IBM JDKs that I could scavenge an old version like this from?


I don't know if this is still true(but this was certainly true in the past), but here is the story.

Due to Java License restrictions earlier, the JDK cannot be provided alone by vendors like IBM.

I am unable to pull this info from any IBM site at the moment but i am pretty certain about these license restrictions in the past.

Here is a post by another gentleman in this space: From : http://www.ibm.com/developerworks/forums/thread.jspa?messageID=14514070

Unfortunately you can get hold of the JDK only as part of another IBM product (say, Websphere or any Rational product) that you purchased. Our licensing agreement with Sun/Oracle forbids us from providing direct downloads of the IBM JDK on any platforms that Oracle/Sun also support (namely Windows and Linux). If you look at the Java downloads section of the developerWorks website, you'll only find SDKs for AIX, z/OS and Linux on System p/z, since those are IBM owned platforms that Oracle doesn't support.

Since the JDK is shipped along with Websphere/Rational/Tivoli products, you can use it if you already have one of them deployed(though even then you may have SR8 FP1, unless you also install the very latest fix packs for those products).
