Develop read-only entity beans
In addition to the existing EJB caching options, you can develop read-only entity beans. You are most likely to want to use it under the following conditions:
- Your application uses data that change relatively infrequently. An example might be a retailing application that uses pricing data that only changes once a week or month.
- Your application can tolerate data that might be stale. The degree of staleness allowed by the EJB container is configurable by the user.
- The bean is coded in a thread-safe manner, so it can safely be invoked by multiple threads at once.
To use this function, declare the bean type as read-only. Declaring a bean type is done the same way that bean caching options are selected - through a selection list within an assembly tool.
To complete this task see the topic, Defining bean cache settings for a bean in the assembly tool information center.
