Re: [Quickfix-developers] Quickfix as Eclipse plugin

[Scott H. <sco...@fo...>]

Marco's problem sounds a lot like what happened to me when I needed to run
under WebStart, which employs a different ClassLoader that JNI's usual
FindClass method is not aware of.  Coupled with QF's current exception
handling under JNI, the resulting failures were difficult to debug even
with CallStack support compiled in.

I have just now added Bug #58 to the bugtracker, and uploaded a ZIP file
attachment with my fix.  These fixes improve JNI support generally, not
just for WebStart or other weird ClassLoader situtations.  Here's an
overview of what I did:

- new quickfix.RuntimeConfig java class
- modified src/java/JVM.cpp to optionally use alternate ClassLoader
- modified src/C++/CallStack.* and Exception.h to be usable from src/java
- added fatalError() function which shuts down the JVM cleanly on coredump
- added CallStack wrappers to JNI code

I'll be happy to discuss these changes and would love to see them merged
into CVS.

P.S. for some reason I cannot read from CVS today.  Is it not still
