When you use a Web container, you can use a resource adapter of the J2EE service to access the database. When you access the database through a resource adapter, Use a DBConnector. When accessing the database, you can use the following functionality:

• JDBC connection pooling
• JDBC connection sharing
• Distributed transaction

For details on connecting to the database, see 3.6 Connecting to the database in the uCosminexus Application Server Common Container Functionality Guide. For settings of the resource adapter for connecting to the database, see 3.6.9 Settings in the execution environment (settings in the resource adapter) in the uCosminexus Application Server Common Container Functionality Guide.
