Hello,
There's a native C function SignalError provided by java
which you can use to throw an exception. When you call the function
in your C program, the program control will be transferred
to the first catch statement which handles the exception in your java code.
However, i don't know of any function which you can use to
catch an exception in the native C mode. You can only throw
an exception in native code.
cheers,
