Class JarClassLoaderFactory

java.lang.Object
  wt.boot.JarClassLoaderFactory

Direct Known Subclasses:

JarClassLoaderFactory_default, JarClassLoaderFactory_sun12

public abstract class JarClassLoaderFactory

extends Object

A factory for class loaders that load from a random access (local) JAR/ZIP file. Instances are specific to Java runtimes because each vendor's applet security manager is tightly coupled to their applet class loaders.

Supported API: true
Extendable: false
