Re: Segmentation faults

Tom,

I am using the char*[] I got out from the jstringarray
using the procedure you showed me last time. I have
printed out the arguments and it seems okay.

Anyway, if this has been done before, I have done
something wrong. I will check that again.

Many thanks for your prompt and helpful replies,

Bryan
