Hi Jonathan,
If you're creating an initial context without any properties ensure
that in your container configuration you specify the type
of jndi plug in being used.
Also ensure that your JNDINames.EMPLOYEE_EJB_HOME is
the same as your <jndi-name> tag in your container configuration.
To use the naming service bundled with the App Server
can set your properties to the following:
Hashtable environment=new Hashtable();
environment.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.cosnaming.CNCtxFactory");
// The ORB we want to use is Orbix2000, which is configured below
// to use our iPAS configuration The following two properties are
// usually found in orb.properties, but in case we haven't
// configured our JRE correctly... see
// http://java.sun.com/products/jdk/1.2/docs/api/org/omg/CORBA/ORB.html
Properties orbProperties = new Properties();
orbProperties.put("org.omg.CORBA.ORBClass","com.iona.corba.art.artimpl.ORBImpl");
orbProperties.put("org.omg.CORBA.ORBSingletonClass","com.iona.corba.art.artimpl.ORBSingleton");
// The ORB name dictates the plugins that Orbix2000 will use. The
// ORB named "iPAS" is preconfigured with certain properies, such
// as the ability to propagate security and transaction contexts.
String[] orbArgs = new String[] {"-ORBname","iPAS"};
environment.put("java.naming.corba.orb", org.omg.CORBA.ORB.init(orbArgs,
orbProperties));
InitialContext initial = new InitialContext(environment);
ok,
Maggie
