Hi Chris,
Thanks for your reply. I recompiled everything and checked method
signature, but still got the same error. I felt it's weird why it worked
for standalone app but not deployed web service... Thanks.
model.java
========
public static void initModel() {
modelJNI.initModel();
}
modelJNI.java
===========
public final static native void initModel();
native code
=========
#include <HEC.h>
#include <vector>
#include <string>
string path="/tmp/model.xml";
HEC *hec_obj;
void initModel() {
hec_obj = new HEC(path);
if (!hec_obj) {
cout << "[ERROR] Cannot instantiate HEC objects.";
}
}
