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
andjakarta.resource.Referenceable
interfaces to support JNDI registration.- Version:

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

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 RecordFactoryNotSupportedException
- 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
