Except for the differences below, the EJB 1.1 client model is identical to the EJB 1.0 model:
Finder method return types Finder methods in EJB 1.1 clients can return java.util.Collection or java.util.Enumeration. Finder methods in EJB 1.0 must return java.util.Enumeration. The use of java.util.Collection is recommended for new development.
Home interface serialization You can call the Home.getHandle method to serialize a home interface proxy in an EJB 1.1 client.
EJBMetaData enhancements The EJBMetaData interface, used by development tools to dynamically inspect EJB components, provides an isStatelessSession method that returns true if the component is a stateless session bean.
