Igor/Barbara,

I must be doing something wrong (of course).  But the program only stops in 
RPGLE and not in java module.  I created java pgm in WDSC, set debug break 
points there, compiled and exported to iSeries (tried both as class and as 
jar). Did the crtjavpgm (on both) I then run RPGLE with start service job in 
another session with a debug on rpgle.  

Please let me know where I am doing wrong.
Thanks in advance,
Sudha

Thanks Barbara.

0091.00 c             IF        curl <> ' ' 
0092.00 c             Eval      iurl      = newString(%trim(curl)) 
0094.00 c             ENDIF 
0094.02

0094.03 c             IF        filename <> ' ' 
0094.04 c             Eval      ifile     = newString(%trim(filename))
0094.08 c             ENDIF 

We seem to have a strange problem after some aldon upgrade on the system
I guess or it was earlier, and we didn't recognize.  We are on v5r3 and
our java methods can only have 2 parameters if we call from command
line.  In my below example, I have 3 since 1st is the class itself and
it seems to be blowing up. I changed the same program and added a main
and called it from cl and it works. I am not sure if anyone else has
encountered such problems and we are now on to IBM for help.

On the debugging java, could you please let me know how, I have never
done that.  I was running from emulator. From rpgle, how can I debug
java? Is this done from WSDC instead? When I go to a debug or Run from
menu bar, I see iSeries modules.  Is this what I go to?

Thanks for your help,
Sudha

Sudha, you didn't show the code where you setup iurlString and
ifileString.  Do they have non-null values?  If so, try debugging the
Java method itself to see what is going wrong.
