If you put -version in your java command line, it'll show you the version that is loaded. If you put -showversion it'll show you and continue to run your class or jar.

The only reliable way to get the version you want loaded is to set the JAVA_HOME environment variable before calling the java command. -D sets a system property which is not quite the same thing. Different versions of the OS have handled java version loading differently.

Thanks for your comments.

Here is what is showing as installed:

5722JC1 *COMPATIBLE Toolbox for Java
5722JV1 *COMPATIBLE Developer Kit for Java
5722JV1 *COMPATIBLE Java Developer Kit 1.3
5722JV1 *INSTALLED Java Developer Kit 1.5

I'm setting the options to include: -Djava.version=1.5

Does that help?

Pete

What version of the JDK are you running on V5R3M0 versus the other platforms? PBEKeySpec was introduced in 1.4.

This is probably a dumb question, but please humor me.

I'm getting "java.lang.NoClassDefFoundError:
javax/crypto/spec/PBEKeySpec"
when trying to apply a digital signature to a PDF using iText.

This is on V5R3M0. The same code works fine on V5R4M0, V6R1M0 and
V7R1M0.

I'm pretty sure it not a case of java not finding the class, more one
of the interface being wrong. Anyone know if this class has changed
between OS/400 releases and/or versions of java?

If anyone can point me in the right direction, it would be greatly
appreciated.

Pete
