Yes, I do know why your stack trace isn't being printed: you need to wrap your entire main in a handler, like this: try { ... ra->run (); } catch (::java::lang::Throwable *ex) { ex->printStackTrace (); } You also need JvAttachCurrentThread (NULL, NULL); That's in the docs, too. You'll then get zorro:tmp $ LD_LIBRARY_PATH=.:/home/aph/gcc/trunk/install/lib64/:. ./RicochetApp Status from JvCreateJavaVM call is 0 Before call to JvInitClass java.lang.UnsatisfiedLinkError: libricochet-jni: libricochet-jni.so: cannot open shared object file: No such file or directory at java.lang.Runtime._load(natRuntime.cc:188) at java.lang.Runtime.loadLibrary(Runtime.java:655) at java.lang.System.loadLibrary(System.java:608) at multishot.examples.RicochetApp.<clinit>(libricochet.so) at java.lang.Class.initializeClass(natClass.cc:780) Andrew. -- Red Hat UK Ltd, Amberley Place, 107-111 Peascod Street, Windsor, Berkshire, SL4 1TE, UK Registered in England and Wales No. 3798903
