RE: Java/RPG interface

Hi Duane,

        In our shop we usually have the rpg program write an entry to a data 
queue
which is serviced by a never ending java program which will then determine
what to do.  There is no start up cost and java has good data queue support
on the 400.

We need to implement a RPG-ILE never ending process (NEP) that reads data
from a file, determines what action that needs to happen based on the file
and then call a java program (methods) that will invoke different soap
methods to accomplish the necessary action.

Our desire is to have the NEP be in RPG since that is the majority of the
programmer base in the company.  The question is how difficult is it to call
java programs (methods) from RPG.  Based on the information I am receiving
it is not easy for RPG to call complex Java programs (methods) that have
many classes.
We are also getting feedback that the JVM does not stay "Active" and may end
at any time. From some of the discussions on this list my understanding that
from V5R2 on you can not intentionally end a JVM let alone have it end
arbitrarily.

Any information would be appreciated.

Thanks
Duane Christen


FYI: We are running on V5R2M0.
