"Compile problem with interface initialization" To view the discussion, visit: https://community.jboss.org/message/749098#749098 -------------------------------------------------------------- Hi there! I implemented code to my project that makes use of javassist. However, I constantly fail to implement an interface to a new class I create. Here is the code I use (adapted from http://www.javaranch.com/journal/200711/Journal200711.jsp#a4): http://www.javaranch.com/journal/200711/Journal200711.jsp#a4): *Main file:* package test; import javassist.*; public class Example2 { public static void main (String[] args) throws Exception { ClassPool pool = ClassPool.getDefault(); CtClass evalClass = pool.makeClass("Eval"+System.currentTimeMillis()); evalClass.setInterfaces(new CtClass[] { pool.makeClass("Evaluator") }); evalClass.addMethod(CtNewMethod.make("public double eval (double x) { return (x*x-x) ; }", evalClass)); Class clazz = evalClass.toClass(); Evaluator obj = (Evaluator) clazz.newInstance(); double result = obj.eval(4); System.out.println(result); } } *Interface "Evaluator":* package test; public interface Evaluator { public double eval (double x); } The code works like a charm in the default package of an Eclipse project (without package test; of course). However, when I use it in a package, I get an Error: javassist.CannotCompileException: by java.lang.NoClassDefFoundError: Evaluator >From trial and interpreting different error messages I guess that the class >loader that should load "Evaluator" refers to the /bin path, while the >Evaluator.class file is to be found in the /bin/test folder. Is there a way to >solve that? Many thanks in advance! -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/749098#749098] Start a new discussion in Javassist at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2062]
