Hello,

I have a jar file that is encrypted and I have a class loader that is able to load the classes. In the jar file there is also interfaces that I would like to implement in my main program. How would I go about doing this. I cant find any way of extracting interfaces from jar files.

If you require more info on what I mean please let me know.

Thanks Mark.

Is this an encrypted jar, or just a packaged jar? Big difference in that you need to know the encryption to decrypt prior to accessing. If its just a packaged jar file, you need to specify the classpath when compiling and running. There are several ways to do so depending upon how you are compiling and running, so you can google "java classpath" and pull up all the different methods.

The jar is encrypted like I said in my original message. The class loader decryptes the classes and I can load the classes by doing the following.

MyClassloader test = new MyClassloader();
Class AClass = test.loadClass("com.AClass");

What I want to do is something like this.

public class TestImplement implements test.loadClass("com.Impclass")
{
}

I have looked at Proxy classes but I dont think what i am doing is possible.
