RE: Executing a jar file from RPG

James,
Java from RPG was not the issue. In fact, I've been doing that since
CLASS became available in RPG.
Spool files are irrelevant. It's HTML I'm transforming to PDF.

So you want to invoke Java methods from RPG? If that's what you are
after
then sure you can do that.

If you are trying to convert a spooled file to a PDF, then there are
LOADS
of solutions for that. If you are just wanting to create PDF documents
check
out PDFBox. It's an open source Java project to create PDF's.

Hope this helps.

is no knowledge of a java interface from RPG that is analogous to the

i5

JAVA cmd which permits either a class or a jar.

Previously, I have been using both the JAVA cmd via CLP and the java
-jar option via QSH with success.
Invoking using this method by referencing a jar file is obviously the
simplest technique but not necessarily the method that performs the
best. I tend to favour RPG because the job has it's own JVM.

As I suspected, I shall have to resort to digging in to the manifest

or

find other material which resolves the actual class to be referenced

in

RPG.

BTW, the product I'm testing is PD4ML, which so far seems to be a
reasonable prospect.

Thanks, Peter

The library website at boulder seems to be down at the mo.



Has anyone had the need to run java from RPG thru a jar file?

I have a java product for which the instruction is to launch by

running

a jar file directly as opposed to a java class.

The i5 supports this technique via the JAVA cmd which will accept

either

a class or jar.



But is there a way to implement this from RPG similar to calling the
Main method of a java class.
