I have a dll written in MSVC++4.2 which I need to use from my JAVA application.
I am trying to use JNI from JBuilder5.The application compiles fine but when the execution reaches the point where the native method is called  I get an UnsatisfiedLinkError.
I should also mention here that I can run the same application from the command line without problems.

I have taken the following steps:
1)Added the following lines of code in the java file(RecorderChange.java)
   public native int Square();
    static
  {
       try{
       
        System.loadLibrary("MyDll");
        
      }catch(java.lang.UnsatisfiedLinkError e)
      {
        System.out.println(e.getClass());
        e.printStackTrace();
      }
  }
//Constructor for the RecorderChange class
public RecorderChange() {
        int s = this.Square();//the line of code that throws the 
                              //UnsatisfiedLinkError
        System.out.println(s);
  }
3)Created the .h file using the javah utility
4)Modified signatures in the C++ file and compiled it   
  incorporating the .h file generated in step 4 above.

Am I missing something, what am I doing wrong. Is there something I need to set up in the JBuilder environment before I can use the jni package.
Any help will be appreciated.
Thanks
