Loading a Dynamic Library on Mac OSX 10.5.6: Unsatisfied Link Error: Matlab

Question

Hi guys,
The Matlab Builder JA generates JAR files that allow you to use Matlab functions in JAVA. I have had a friend run through the process of creating the files and running them on WINDOWS and it works fine, but it fails on Mac OSX.
The program uses the JAR file displayTest2.jar, and also requires the JAR file javabuilder.jar, which are both loaded as external JARS in eclipse. My code is as follows:
{color:#0000ff}import com.mathworks.toolbox.javabuilder.*;
import displayTest2.*;
public class Tester
public static void main(String[] args) throws MWException
System.out.println("Hello");
DisplayTest2 object = new DisplayTest2();
}{color}
This gives the following output:
Hello
{color:#ff0000}Exception in thread "main" java.lang.UnsatisfiedLinkError: Failed to find the library libmwmclmcrrt.7.10.dylib, required by MATLAB Builder JA, on java.library.path

at displayTest2.DisplayTest2.<init>(DisplayTest2.java:61)
at Tester.main(Tester.java:9){color}
I have tried placing the missing library in the folders on java.library.path, but this has no effect. I have also tried loading the library like so:
{color:#0000ff}public static void main(String[] args) throws MWException
System.out.println("Hello");
System.load("/Applications/MATLAB/MATLAB_Compiler_Runtime/v710/runtime/maci/libmwmclmcrrt.7.10.dylib");
DisplayTest2 object = new DisplayTest2();
}{color}
But I get the following output:
Hello
{color:#ff0000}Exception in thread "main" java.lang.UnsatisfiedLinkError: /Applications/MATLAB/MATLAB_Compiler_Runtime/v710/runtime/maci/libmwmclmcrrt.7.10.dylib:
at java.lang.ClassLoader$NativeLibrary.load(Native Method)
at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1822)
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1702)
at java.lang.Runtime.load0(Runtime.java:770)
at java.lang.System.load(System.java:1005)
at Tester.main(Tester.java:8){color}
Is this not the correct way to load the library? I have scoured the internet to the best of my ability but can&rsquo;t find any solutions. As I said it works on Windows. Is there something special that needs to happened on Mac OSX. I could just develop on Windows, but there has to be a way to make it work on Mac, right?
I appreciate any help at all so I can get on with my project!
Thanks,
--John
