You must call JvCreateJavaVM() before making any calls to Java code from 
an application with a C/C++ "main" method. eg:

--- orig/javatest.cpp Thu Mar 28 11:28:23 2002
+++ javatest.cpp Thu Mar 28 11:26:26 2002
@@ -7,6 +7,7 @@
 {
 printf("Starting...\n");
 
+ JvCreateJavaVM(NULL);
 otherclass *ttt = new otherclass();
 
 printf("Otherclass created (%p)\n",ttt);
Note that this only works with GCJ 3.1 and up.
