RE: Off Topic: A suitable JVM could not be found

I can't find the details right now, but I have a vague recollection that the
IBM JDK includes an RMI-IIOP implementation that is a requirement for
Websphere. So you won't be able to switch to a non-IBM JDK.

If you're running just about anything except Windows, you may be able to use
an updated IBM JDK (http://www-106.ibm.com/developerworks/java/jdk/).
IBM has not separately released its 1.4 version for Windows, though it is
available bundled with products like MQ Series (sorry, Websphere MQ -
marketing dept strikes again).

I don't have any information on whether it's *advisable* to change the JDK
on Websphere, since it doesn't seem to be supported. Personally, I wouldn't
risk it in a production environment.

There actually is a package that you can use for a Java client to 
provide the RMI-IIOP client package that is required to connect to a Web 
Sphere application (assuming that it's a larger J2EE application), but 
this doesn't help you in terms of running the application server itself.

Also, that "package" might seem to be part of a simple "here's a jar you 
should use," but in fact it's a whole slew of jar files and environment 
variables you have to run, and those jar files have to be in a 
particular file system layout in order to function (i.e. you can't just 
make sure they're in your classpath).

Steve-
Thanks for the quick response.
I found that you can obtain the IBM JDK,JRE by downloading IBM WebServices

If IBM could state how their JDK,JRE is compatible with other environments
(Ant specifically) then I would be more willing to replace the JAVA_HOME

IBM like Microsoft doesnt offer any support unless you're willing to pay
them.
which to my way of thinking runs counter for the justifications of open
source
Thanks again,

Martin Gainty
