## Class ContextFactory

- java.lang.Object
- - org.eclipse.jetty.jndi.ContextFactory

- All Implemented Interfaces:
    ObjectFactory

      public class ContextFactory
      extends Object
      implements ObjectFactory

  ContextFactory.java This is an object factory that produces a jndi naming context based on a classloader. It is used for the java:comp context. This object factory is bound at java:comp. When a lookup arrives for java:comp, this object factory is invoked and will return a context specific to the caller's environment (so producing the java:comp/env specific to a webapp). The context selected is based on classloaders. First we try looking in at the classloader that is associated with the current webapp context (if there is one). If not, we use the thread context classloader. Created: Fri Jun 27 09:26:40 2003

      Specified by:
        `getObjectInstance` in interface `ObjectFactory`
      Throws:
        `Exception`
