loadjava utility for osx

Question

Is there a loadjava utility for OSX or a way to load my java classes to Oracle database from mac os? I am trying to execute a java stored procedure using eclipse from mac os and I am not able to load my java classes into the Oracle database.

This is my java class

public class CallJava {
public static String welcome() {
    return "Welcome to Java";
}
}

and this is my sql query to invoke the java class

CREATE OR REPLACE FUNCTION call_CallJava RETURN VARCHAR2 AS
LANGUAGE JAVA
NAME'CallJava.welcome() return java.lang.String';
/

I am able to do it on the windows machine using the loadJava utility and my question is how can I do this on mac os.
