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 javax.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

• getRecordFactory

  RecordFactory getRecordFactory()
                          throws ResourceException

  Gets a RecordFactory instance. The RecordFactory is used for the creation of generic Record instances.

  Returns:

  RecordFactory RecordFactory instance

  Throws:

  ResourceException - Failed to create a RecordFactory

  NotSupportedException - Operation not supported

• 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
