Class EJB11Context

java.lang.Object

org.openxava.ejbx.EJB11Context

All Implemented Interfaces:

java.io.Serializable, IEJBContext, IEJBContextInit, IConnectionProvider

public class EJB11Context
extends java.lang.Object
implements IEJBContextInit, java.io.Serializable

Implementation of IEJBContext for a EJB 1.1 server.

Since EJB 1.1 standardizes enough things only it's needed one version, and it is not required additional properties files.
If you can use getConnection() without argument, you need to define in the bean a property named DATA_SOURCE that indicate the default data source.

In the DATA_SOURCE property you can put also the username and password by default, thus datasource;usuario;clave.
