## weblogic.jndi
Class Environment

    java.lang.Object
      weblogic.jndi.Environment

All Implemented Interfaces:
  Externalizable, Serializable, ClientEnvironment

    public final class Environment

extends Object
implements Externalizable, ClientEnvironment

The Environment class represents the properties used to create an initial Context. It provides type-safe methods to set and get common JNDI properties and a convenient way to create a new initial Context. Although this class uses WLInitialContextFactory as its default factory, it may be used to create an initial Context using any legal factory.

Here's an example of how to create an initial context:

       Hashtable props = new Hashtable();
       props.put(Context.INITIAL_CONTEXT_FACTORY,
                 "weblogic.jndi.WLInitialContextFactory");
       props.put(Context.PROVIDER_URL,         "t3://weblogic:7001");
       props.put(Context.SECURITY_PRINCIPAL,   "fred");
       props.put(Context.SECURITY_CREDENTIALS, "seafood");
       Context ctx = new InitialContext(props);

This code can be rewritten using an Environment object as illustrated here:

      Environment env = new Environment();
       env.setProviderUrl("t3://weblogicServer:7001");
       env.setSecurityPrincipal("fred");
       env.setSecurityCredentials("seafood");
       Context ctx = env.getInitialContext();
