Subject Re: JNI error under tomcat: java.lang.UnsatisfiedLinkError
Date Mon, 05 Jul 2010 07:35:07 GMT
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.";
   }
 }
