I want to send an object from from one JVM to another through message
queue. for that i wrote a JNI program which takes an jobject as a
parameter. now i want to pass this object to another native code throgh
message queue.

struct mesg{
int type;
jobject sendobj;
};

JNIEXPORT void JNICALL Java_server_share(JNIEnv *env,jobject obj,jobject sendobj)


{
struct mesg m;
m.sendobj=sendobj;
int ser_mq=CreateMQ();
WritetoQue(ser_mq);
}

when i run the program, the server program run without any errors. But
at the client side i am not able to call the class of the object
received.

JNIEXPORT jobject JNICALL Java_client_share(JNIEnv *env,jobject obj)
{

int mqid = create();
struct mesg que=readfromque(mqid);
jobject robj=que.recvobj;


jclass cls2=(*env)->;GetObjectClass(env,robj);/* ERROR*/

return robj;
}

neither i could use the received object(return robj) to retrieve its
field.

Is there any way to send a jobject from one C code to another through
message queue or any other IPC mechanisms?
Any help is much appreciated...
