java.lang.Object
  org.openejb.client.proxy.Jdk13ProxyFactory

All Implemented Interfaces:

ProxyFactory

public class Jdk13ProxyFactory
extends Object
implements ProxyFactory

Implementation of ProxyFactory for JDK 1.3 Proxies. This only compiles on JDK 1.3 or better. It is very fast because it builds the proxies out of raw bytecode.
