Re: Determining Which JVM is running on OS/400

["David Morris" <David.Morris@xxxxxxxxxxxxx>]

Shannon,

You can set the version through a SystemDefault.properties file, or by

specifying a property when you start java with -Djava.version=1.x. 
You should only need to manipulate your classpath to add things like 
the tools.jar or some other optional part of the JDK.

To get the current version you might try something like: 

String version = System.getProperty("java.version");

Hi,

Probably a dumb question....


I have three JDK's on my V5R1 system (JDK118,  JDK12, JDK13). How do I
determine which JDK is being used? By what I set in the CLASSPATH,
right?

The reason I ask....is because I'm using some software from Verisign to
do a
Credit Card authorization from the AS/400.  One of the things I need to
do
is to set the security provider(s), in my java.security file under the
/QIBM/ProdData/Java400/jdk13/lib/security/java.security
or..../QIBM/ProdData/Java400/jdk12/lib/security/java.security.....or...../QI
BM/ProdData/Java400/jdk118/lib/security/java.security .

I've set this information in all three versions of that file (the
"shotgun"
approach to programming...) and yet, when I run the app, I still get
an
error telling me that the security informaiton (that specific
information)
has not yet been set.

So...I'm wondering if the reason it can't see my updates to the
java.security file is due to a CLASSPATH problem, or possibly
something
else.

I know this is probably vague...but hoping for a suggestion or two I
might
try anyway!

Thanks!
