Hi,
My little JNI HelloWorld C++ program hangs when invoking
JNI_CreateJavaVM() with following output:
> export LD_BIND_NOW=true
> export RTLD_NOW=true
> invokecpp
<GC: need to expand mark bits to cover 16384 bytes>
[Opened /usr/local/jdk1.2Pre1/jre/lib/rt.jar in 29 ms]
[Opened /usr/local/jdk1.2Pre1/jre/lib/i18n.jar in 4 ms]
-> here it stays forever ....
The old version, calling the JDK 1.1 interface (Blackown Java 1.1.7)
runs fine.
CAN ANYBODY PROVIDE ME A LITTLE HELLOWORLD JNI SAMPLE CODE WHICH WORKS?
I couldnt find any example for the new JDK-2 JNI API, so perhaps im
using it wrong.
My Environment:
-------------
- Pentium Linux 2.0.36 with glibc
- jdk1.2pre-v1.tar from Blackdown
How i compiled it:
-------------
export LD_BIND_NOW=true
export RTLD_NOW=true
g++ -D_REENTRANT -I/usr/local/jdk/include -I/usr/local/jdk/include/linux
invoke.C -o invokecpp -L/usr/local/jdk/jre/lib/i386 -ljava -L
/usr/local/jdk/jre/lib/i386/native_threads -lhpi
-L/usr/local/jdk/jre/lib/i386/classic -ljvm
How invoke.C looks like:
------------------
#include <jni.h>
main()
{
JNIEnv *env;
JavaVMInitArgs vm_args;
JavaVMOption options[4];
options[0].optionString = "-Djava.compiler=NONE"; /*
disable JIT */
options[1].optionString = "-Djava.class.path=."; /* user
classes */
options[2].optionString = "-Djava.library.path=."; /* set
native library path */
options[3].optionString = "-verbose:jni,class,gc"; /* print
JNI-related messages */
vm_args.version = JNI_VERSION_1_2;
vm_args.options = options;
vm_args.nOptions = 4;
vm_args.ignoreUnrecognized = JNI_TRUE;
JavaVM *jvm;
jint res = JNI_CreateJavaVM(&jvm, (void **)&env, &vm_args);
..... here it hangs :-(
Thanks very much for any hint,
Marcel
