Re: Find if RPGLE program called from Java or other RPG program

Hi
I am using PCML(ProgramCall) to call RPG program, the way i do it is

In Java program i create a MessageQueue with User id in QTEMP library
For example user signed in is ASHISH then i create a MessageQueue ASHISH in QTEMP from Java using CommandCall.

In RPG i simply get the user name from Data Structure and then use this name to locate the MessageQueue from QTEMP and write messages to it,

In Java i read those messages and display them on web page.

It is as simple as this and is working fine so far over past few years.

Make sure you have QTEMP in library list and there is no other MessageQueue object conflicting.

Hope this helps,



A$HI$H

Hi
I have already done some thing like that to pass

messages from QTEMP, create a message queue and pass error
messages from RPG to Java.

I call RPG program from Java, this RPG program writes

error messages in message queue created in QTEMP library,
when the control comes back to Java program i read these
error messages from message queue in QTEMP.

So RPG and Java have the same QTEMP.

Using a ProgramCall or with JNI? Any particulars to
remember when doing so?

I reason i want to add some special logic when called

from RPG is because we this logic to clear from tables if
called from RPG,

Sounds brittle. Can't you add a flag or an extra call
to do this?
