Hi all,
I am facing problem in calling a native method more than once in java.
The native method('C') basically implements socket part to collect some
data from other machine.
JDK 1.2pre-v2 (glibc2.1), Linux : RedHat6.0.
It gives the correct value once, but for the second time it is called,
it core dumps with following error.
Any Help/Suggestions are most welcome.
Thanks in advance,
Nagaraj S.B.
