All EJB types within a server can be forced to initialize at application start time by setting a system property within the administrative console. If the value of this property is set to true, then all beans within the server are initialized at each application's start time.
Why and when to perform this task
However, by default, the WebSphere Application Server's Enterprise JavaBeans (EJB) Container delays the initialization (loading of classes and processing of deployment descriptor metadata) of most EJB types until they are needed during run time. This delay helps to speed up the application start time.
