javassist.CannotCompileException when using interfaces

[derari]

Hello,

I could not find a solution for my problem, hopefully someone can help me.

In my project, I am using logging like this:

public interface Logger {
    public void info(String s);  
    public void debug(String s);
}

public class LoggerImpl implements Logger {

    // ...

}

No I want to generate a proxy class that implements Logger, but when I try to compile

private DynamicProxy dp;
public void debug (java.lang.String p0) {
    Logger i = (Logger) dp.getImplementation();
    i.debug(p0);
}

I get "javassist.CannotCompileException: [source error] debug(java.lang.String) not found in dynproxy.test.Logger", whereas

private DynamicProxy dp;
public void debug (java.lang.String p0) {
     LoggerImpl i = (LoggerImpl) dp.getImplementation();
     i.debug(p0);
}

works fine, but is no valid solution for the problem. (The idea is to have a proxy that uses the Logger implementation that is registered with the DynamicProxy object)

So please tell me, what can I do to make it work?

I found it after a lot of trying

the tutorial I was using said

proxyClass.setInterfaces(
                    new CtClass[] { pool.makeClass(iface.getCanonicalName()) });

is the way to extend an Interface, but

proxyClass.setInterfaces(
                     new CtClass[] { pool.get(iface.getCanonicalName()) });

made it work.
