    public class JdbcAccessorImpl
    extends java.lang.Object
    implements WSNativeConnectionAccessor
    This class provides a conduit for the WebSphere ResourceAdapter CCI function to access the Native Connection. All Native Connection accesses are funneled through the methods on this object.

    This is the Generic JdbcAccessor, for accessing non-WebSphere-specific Native Connections.

    A DataSource is passed to this object on the constructor. The getConnection() methods use the DataSource to create new Native Connections. The Native Connections are stored in the CCI Connection objects, and passed back to this object when a Native Connection method is invoked.

      • getConnection

        public java.lang.Object getConnection(WSCciConnectionSpec connectionSpec)
                                       throws javax.resource.ResourceException
        Deprecated. 
        This method gets a native connection. A component must use the getConnection variant with com.ibm.websphere.rsadapter.WSConnectionSpec parameter if it needs to pass any resource adapter specific security information and connection parameters. In the component-managed sign-on case, an application component passes security information (example: username, password) through the ConnectionSpec instance.

        It is important to note that the properties passed through the getConnection method are be client-specific (for example: username, password, language) and not related to the configuration of a target database instance (example: port number, server name). The ManagedConnectionFactory instance is configured with the complete set of properties required for the creation of a connection to a database instance.

        Specified by:
        getConnection in interface WSNativeConnectionAccessor
        Parameters:
        connectionSpec - - Connection parameters and security information specified as a com.ibm.websphere.rsadapter.WSConnectionSpec instance
        Returns:
        a Native Connection instance
        Throws:
        javax.resource.ResourceException - - Failed to get a connection instance. Examples of error cases are:
        • Specification of input parameters that are not valid
        • Configuration of ManagedConnectionFactory that is not valid; for example: a server name that is not valid
        • Application server-internal error; for example: connection pool related error
        • Communication error
        • EIS-specific error; for example: database not active
        • Resource adapter-internal error
        • Security related error; for example: user that is not valid
        • Failure to allocate system resources
      • getConnection

        public java.lang.Object getConnection()

        Deprecated. 
        This method gets a native connection. Use this getConnection variant when a component wants the container to manage EIS sign-on. This case is termed container-managed sign-on. The component does not pass any security information.

                   throws javax.resource.ResourceException
        Deprecated. 
        This method initiates a close of the connection. A client should not use a closed connection.

        nativeConnection - - the Connection on which to do the close()
        Throws:
        javax.resource.ResourceException - - Exception thrown if close on a connection fails.

        Any invalid connection close invocation--example, calling close on a connection that is already closed--should also throw this exception.
