Niladri Sen

Hi all,

I am having a snag implementing a native method which throws an java.lang.UnsatisfiedLinkError in my output. For the basic instance, java static library is found OK to load, whereas the output shows the following:

Exception in thread "main" java.lang.UnsatisfiedLinkError: com.sen.niladri.www.natives.Replication.getSecurity(I)Lcom/sen/niladri/www/natives/Normalize; at com.sen.niladri.www.natives.Replication.getSecurity(Native Method) at com.sen.niladri.www.natives.Security.getSecurity(Security.java:42) at com.sen.niladri.www.natives.Security.loadLibrary(Security.java:39) at com.sen.niladri.www.natives.Replication.<clinit>(Replication.java:10) at com.sen.niladri.www.natives.Security.getSecurity(Security.java:42) at com.sen.niladri.www.natives.Security.loadLibrary(Security.java:39) at com.sen.niladri.www.natives.Security.<clinit>(Security.java:11) at com.sen.niladri.www.natives.Orientation.<clinit>(Orientation.java:6) Could not find the main class: Main. Program will exit.

I am intended to furnish some basic implementation of my classes here:

Replication.java

public class Replication extends Orientation { public static native Normalize<?> getSecurity(int finalDestination); // The hitch is hidden behind this line }

Security.java

public class Security extends Orientation { static Normalize getSecurity() { return Replication.getSecurity(3); } }

The vast snag comes to the class Normalize in Replication.java having a native method within this. I am also having a header file implementing the class as follows:

Normalize.h

#ifndef __NORMALIZE_H__ #define __NORMALIZE_H__ #pragma BCC32 java-exceptions typedef "Java" { namespace com { namespace sen { namespace niladri { namespace www { namespace natives { class Normalize; class Orientation; class Security; } } } } } } typedef class com::sen::niladri::www::natives::Normalize *jnorm; typedef class com::sen::niladri::www::natives::Orientation *jorien; typedef class com::sen::niladri::www::natives::Security *jsecure; #endif

And now when am going to implement the Normalize class as a native method as described in Replication.java my Replication.h file implemented like:

Replication.h

... JNIEXPORT jnorm JNICALL Java_com_sen_niladri_www_natives_Replication_getSecurity(JNIEnv *, jclass, jint); ...
So my snag is whether am I using the code wrongly, I mean am I supposed to use jnorm in Replication.h such way that I furnished?

My english knowledge is not perfect, so any help in this regard is highly appretiated.

Thank you in advance.
