RE: Calling java pgm on remote server from RPG

["Rooney, Michael P [CI]" <michael.p.rooney@xxxxxxxxxxxxx>]

Phil,

Let me first state that my expertise is NOT in Java.  I am familiar with
the language enough to be dangerous.

Now that I've level set your expectations.........

Within my confined java knowledge there are 2 possible solutions (I'm sure
there are more but..see my first sentence) that, if you've never used either
before, will probably involve considerable trial and error.  Access to a good
java developer wouldn't hurt.

As you have some experience using stored procedures, one approach might be
to use JDBC to invoke a stored procedure on the Unix box which, in turn, invoked
the java program.  Some preliminary information on JDBC (i.e. the java.sql 
class)
can be found at:

http://java.sun.com/j2se/1.3/docs/api/java/sql/package-tree.html

The approach involves using Java's RMI (Remote Method Invocation) API.  The RMI
was designed to support the invocation of remote java methods so it might be
what you're looking for.  Some info on RMI can be found at:

http://java.sun.com/j2se/1.4.2/docs/guide/rmi/ --> has tutorial & examples in 
java!

http://java.sun.com/developer/technicalArticles/RMI/rmi_corba/

http://java.sun.com/docs/books/tutorial/rmi/overview.html

http://java.sun.com/developer/codesamples/rmi.html
 
http://java.sun.com/docs/books/tutorial/rmi/

As I've never used either of these java features, I can't endorse one
or the other.  Hopefully this information gives you some options to ponder.


Good luck,

Subject: Calling java pgm on remote server from RPG


List,

I have a request to call a java pgm on a unix box from an RPG app.  I
know how to do this between two as400's using stored procedures but I've
never done it where the remote server wasn't an as400 and where the
remote pgm wasn't RPG, COBOL, or C.  

Can someone point me to some documentation?

Thanks,

Phil
