Java Programming

Hi,

I have been given a .so file from a third party that is developed in C++. The file is named convertor.so


If i run

objdump -tT convertor.so 

I get the following where the method I need to invoke in Java is named ConvertSingle, it is listed in the dynamic symbol table rather than the symbol table

convertor.so.so:     file format elf32-i386
SYMBOL TABLE:
no symbols
DYNAMIC SYMBOL TABLE:
0000af40 g    DF .text	0000034a  Base        ConvertSingle 

I have created a Java class as follows;

public class ConvertClass{

        static{
          System.loadLibrary("convertor");
        }
        private native int  ConvertSingle(byte[] byteArray);

        public static void main(String args[]){

            ConvertClass myClass = new ConvertClass():
          }
         } 

But if I try to invoke my compiled class using java ConvertClass, I am constantly getting the error below;

exception in thread "main" java.lang.UnsatisfiedLinkError: no convertor in java.library.path
	at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1738)
	at java.lang.Runtime.loadLibrary0(Runtime.java:823)
	at java.lang.System.loadLibrary(System.java:1028)
	at ConvertClass.<clinit>(ConvertClass.java:5)
Could not find the main class: ConvertClass.  Program will exit.
 

I have set the ld_libray_path

LD_LIBRARY_PATH=.
export LIBRARY_PATH
ldconfig.
 

Could anyone help as to what I might be doing wrong?

Any help would be very much appreciated.

many thanks.
DM
