Chapter 27: Creating Entity Components
For EJB 2.0 entity beans, choose a CMP version on the General tab in the Component Properties dialog box. Choose 2.0 to match the EJB 2.0 specified behavior. Choose 1.1 to match the EJB 1.1 persistence model. Use 2.0 CMP for new development, and 1.1 for existing beans that have code that requires the 1.1 model.
For EJB 1.1 entity beans, you can not set the CMP version.
