Interface ConnectionFactory

  • All Superinterfaces:
    Referenceable, Referenceable, Serializable
    public interface ConnectionFactory
extends Serializable, Referenceable
    ConnectionFactory provides an interface for getting connection to an EIS instance. An implementation of ConnectionFactory interface is provided by a resource adapter.

    Application code looks up a ConnectionFactory instance from JNDI namespace and uses it to get EIS connections.

    An implementation class for ConnectionFactory is required to implement java.io.Serializable and jakarta.resource.Referenceableinterfaces to support JNDI registration.

    • Method Detail

      • getConnection

        Connection getConnection()
                  throws ResourceException
        Gets a connection to an EIS instance. This getConnection variant should be used 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.
        Returns:
        Connection instance
        Throws:
        ResourceException - Failed to get a connection to the EIS instance. Examples of error cases are:
        • Invalid configuration of ManagedConnectionFactory-- example: invalid server name
        • Application server-internal error--example: connection pool related error
        • Communication error
        • EIS-specific error--example: EIS not active
        • Resource adapter-internal error
        • Security related error; example: invalid user
        • Failure to allocate system resources

      • getConnection

        Connection getConnection​(ConnectionSpec properties)
                  throws ResourceException
        Gets a connection to an EIS instance. A component should use the getConnection variant with jakarta.resource.cci.ConnectionSpec 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 should be client-specific (example: username, password, language) and not related to the configuration of a target EIS instance (example: port number, server name). The ManagedConnectionFactory instance is configured with complete set of properties required for the creation of a connection to an EIS instance.

        Parameters:
        properties - Connection parameters and security information specified as ConnectionSpec instance
        Returns:
        Connection instance
        Throws:
        ResourceException - Failed to get a connection to the EIS instance. Examples of error cases are:
        • Invalid specification of input parameters
        • Invalid configuration of ManagedConnectionFactory-- example: invalid server name
        • Application server-internal error--example: connection pool related error
        • Communication error
        • EIS-specific error--example: EIS not active
        • Resource adapter-internal error
        • Security related error; example: invalid user
        • Failure to allocate system resources

      • getMetaData

        ResourceAdapterMetaData getMetaData()
                             throws ResourceException
        Gets metadata for the Resource Adapter. Note that the metadata information is about the ResourceAdapter and not the EIS instance. An invocation of this method does not require that an active connection to an EIS instance should have been established.
        Returns:
        ResourceAdapterMetaData instance
        Throws:
        ResourceException - Failed to get metadata information about the resource adapter
