Stateful Oracle Web services using J2EE 1.4 with JAX-RPC

Stateful Oracle JAX-RPC web services are using specific HTTP headers from the client calling the Web Service that need to be setup if you want the Stateful web service to work.

Call the following set property in your client proxy:

setMaintainSession(true) otherwise the service will work as a stateless service. Also regular browsers don't support the http header extension.

Using Data Sources

These are links to data source topics.
Sun Datasource has been extended by Oracle as OracleDataSource();
The library to include in your project in Jdeveloper is named Oracle JDBC.

You can provide database credentials to a datasource or use JNDI (Lookup). The avantage of using JNDI is that no credentials are hardcoded.
