Java: defineClass and inner classes

Question

In my own classloader I get all entries from jar file and use defineClass() to load classes to memory.

My problem is that if jar has inner classes (eg MyClass$1.class) the defineClass method fails with java.lang.NoClassDefFoundError: IllegalName exception.

Obviously java needs all files from jar to make it work but how the inner classes can be loaded?

Answer 1

MyClass$1.class should match an anonymous inner class. If your inner class is named, it should be MyClass$InnerClass.class
