Hi Paul,

Personally, I have never seen the benefit of using loadjava, *if* you have the following two things:

1. the source code.
2. You don't *need* functionality in another JVM like 1.5, such as the Lock object. Code compiled using 1.4 can be run under a 1.5 JVM, as shown below...

public class getVersion {
  public static void main(String args []) {     try {
      System.out.println(System.getProperty ("java.version"));     }
    catch (Exception err) {
      err.printStackTrace();
    }
  }
}

C:\SCRIPTS\java>java getVersion
1.5.0_06

C:\SCRIPTS\java>C:\oracle\product\10.2.0\db_1\jdk\bin\java getVersion 1.4.2_08

Can you post the exception being thrown?
