Java Database Connectivity (JDBC)

Dear Friends:

I have a problem accesing an Oralce database. The most courious thing is that this code works fine in Windows but not in Linux (red hat 8, jvm1.4.1). The exception is javax.naming.NoPermissionException; remaining name '"/"'.

I connect to the database.with the following code:

(...)

entorno=new Hashtable();
entorno.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.fscontext.RefFSContextFactory");
//entorno.put(Context.PROVIDER_URL,"file:.");

ctx=new InitialContext(entorno);

ocpds=new OracleConnectionPoolDataSource();
ocpds.setDriverType("thin");
ocpds.setNetworkProtocol("tcp");
ocpds.setServerName(servidor);
ocpds.setDatabaseName(sid);
ocpds.setPortNumber(puerto);
ocpds.setUser(usuario);
ocpds.setPassword(contrasena);

ctx.rebind(nombreFuenteDatos,ocpds);
ocpds=(OracleConnectionPoolDataSource)ctx.lookup(nombreFuenteDatos);

ocache=new OracleConnectionCacheImpl(ocpds);

ocache.setMaxLimit(NUMERO_MAXIMO_CONEXIONES);
ocache.setMinLimit(NUMERO_MINIMO_CONEXIONES);

ocache.setCacheScheme(ocache.DYNAMIC_SCHEME);
(...)




It fails when I make the rebind instruction. I have another question: �is that the best way to connect to an Oracle database? I have observed that when I connect with the db, in the directory where the program is running appears a file called ".bindings", with all the information about the connection. I don't like that very much, but I don't know another way to make it.

We are working in an intranet with 3 different Oracle servers and a lot of clients (more than 100). The Java aplication is on an different server, and I distribute the application with Java Web Start.

As I say, it works fine on Windows, but we are thinking to change al the clients to linux (works better), but I have this little problem.

Thank you very much.

Roque.
