RE: Java and cleanup from exception

... same question, different environment. Once a java routine blows up in
the batch job, you'll have the same issue but at higher cost. What do you
do about that?

But it sounds like you are using embedded java; you're just not using it
interactively. Else why are you starting JVM at all?

... I don't use this "embedded Java" in RPG at all, I always put one
JVM to a
Batchjob, serving multiple RPG Clients via DataQ. IMHO this approach
has
multiple advantages:
- no startup punishment
- better scalability, than starting JVMs for many Jobs
- no need to put everything to the system classpath
I have written open Source AppServer4RPG (hosted at SourceForge) it has
a RPG
Part with a procedure fireEventP, sending a Request with a name and
Requestdata ro the prestarted JVM. You would have to write a Java
RequestHandler (for every Request Name).
In the meantime there is a complete application as example available
(ArdGate,
an universal database driver - with this you can access every database
with
embedded SQL)

For years, I have been writing programs that utilize RPG's interface

with

Java for functions like (especially) creation of spreadsheets,

creation of

charts and the like. For the same years, I have found that when Java
errors occur when testing those functions (obviously due to external
influences like sunspots - not my code! ;) the interactive job is

virtually

useless to Java. Cannot start a new Java session, and cannot recover

the

old one.

From my experience, JBAB55C results in any attempt to use Java after

a

failure, often accompanied by an amazing number of MCH* errors.



What do others do to clean up from this so they don't have to sign

off and

back on every time the sun has a mild hiccup? I'm sure this is

something I

should have addressed all those years ago, but here I am now.
