Develop applications that use EJB query
- EJB query language
EJB query language enables you to write queries based on entity beans without knowing the underlying relational schema.
- Use the dynamic query service
There are times in the development process when you might prefer to use the dynamic query service rather than the regular EJB query service (which can be referred to as deployment query). During testing, for instance, the dynamic query service can be used at application run time, so you do not have to re-deploy the application.
