Re: Improving Excel generation performance through calling Java

Hi Darren,

So far my results are, with running both ways twice, using the standard
HSSF api's from pure RPGLE it took 11 minutes. Coding the 4 steps to
create row in java, called from RPG, takes 5 minutes.

That absolutely startles me. Were you doing garbage collection properly in your RPG version?

This method still requires creating a java string object to pass to the
create cell routine, so there is still a memory leak in that step, but I
cannot think of a way around that issue.

Why not pass a byte string to the create cell routine? Then you could pass an RPG-style alphanumeric string directly to the Java routine. The Java routine would use the byte[] to create the String object.
