RE: Free Java Objects In RPG

Okay, stupid question.  Where do I found if I'm update to date with these
ptfs (this is new to me)?  I think the last one we have is SF99530.

I was seeing heap operation errors a couple of months ago on some http
stuff. I applied the latest HTTP, database and group ptfs and it seemed
to fix it. At least I haven't seen it since. This was on V5R3.

Subject: Free Java Objects In RPG


Good morning all,

I'm having trouble with one of CGI Web RPG programs.  This particular
web
program is using java to get data from a windows machine.  At the start
of
the program, I start my grouping of java objects.

 temp = BldJavaStr('a');
 env = getJniEnv();
 beginObjGroup (env : 10000);

Then go on to execute my custom java apps to retrieve the data.

When finished, I free my object group.

endObjGroup (env);
freeLocalRef (env : temp);


This works most of the time, however there are times when I get the
following messages in the job log...

The requested heap space operation is invalid.
The pointer parameter passed to free or realloc is not valid.

These don't stop the program from running, however, there are times a
system error will pop up (this doesn't occur on every run) and cause the
program to stop running.

Does anyone have experience with this error message?  I thought it had
something to do with the  temp variable (temp = BldJavaStr('a');) when
passed to the freelocalref procedure.  I just can't seem to figure out
what's going on.
