Don't Use the Composite Entity Bean Pattern.
Use a Field-Naming Convention to Allow for Validation in EJB 2.0 CMP Entity Beans.
Don't Get and Set Value/Data Transfer Objects on Entity Beans.
Using Java Singletons Is OK If They're Used Correctly.
Prefer Scheduled Updates to Real-Time Computation.
Use a Serialized Java Class to Add Compiler Type Checking to Message-Driven Bean Interactions.
Always Call setRollbackOnly when Application Exceptions Occur.
Limit Parameters to ejbCreate.
Don't Use Data Transfer Objects in ejbCreate.
Don't Use XML to Communicate as a DTO Mechanism Unless You Really, Really Have To.
