Re: DBCP Registering a PoolingDataSource in JNDI

[Dirk Verbeeck]

I created the following subclass:
class ReferencablePoolingDataSource extends PoolingDataSource 
implements Referenceable

and the exception goes away.

Tomcat initializas its JNDI tree using a Reference and a 
ObjectFactory, that's also a way to do it.

I'm trying to register a valid PoolingDataSource in JNDI using the following
method and code:
        private final static String INITIAL_CONTEXT_FACTORY =
"com.sun.jndi.fscontext.RefFSContextFactory";
        private final static String FACTORY_URL = "file:/D:/jndi";
        public static void register(PoolingDataSource datasource, String
bindName) throws Exception {
                Hashtable env = new Hashtable();
                env.put(Context.INITIAL_CONTEXT_FACTORY,
INITIAL_CONTEXT_FACTORY);
                env.put(Context.PROVIDER_URL, FACTORY_URL);
                
                Context context = null;
                try {
                        context = new InitialContext(env);
                }
                catch (NamingException e) {
                        String msg = "Could not initialize the context : " +
e.getMessage();;
                        _log.error(msg);
                        e.printStackTrace();
                        throw new Exception(msg);
                }
                
                try {
                        context.rebind(bindName, datasource);
                }
                catch (NamingException e) {
                        String msg = "Could not bind the datasource : " +
e.getMessage();
                        _log.error(msg);
                        e.printStackTrace();
                        throw new Exception(msg);
                }       
        }       
The problem happens with the call to context.rebind. Apparantly JNDI is
complaining as follows:
javax.naming.OperationNotSupportedException: Can only bind References or
Referenceable objects
        at
com.sun.jndi.fscontext.RefFSContext.addObjectToBindings(RefFSContext.java:47
9)
        at
com.sun.jndi.fscontext.RefFSContext.bindObject(RefFSContext.java:337)
        at com.sun.jndi.fscontext.RefFSContext.rebind(RefFSContext.java:189)
        at com.sun.jndi.fscontext.FSContext.rebind(FSContext.java:194)
        at javax.naming.InitialContext.rebind(Unknown Source)
Any ideas on what's wrong?
