Examples of org.apache.openejb.jee.MessageDrivenBean

org.apache.openejb.jee.MessageDrivenBean
The message-driven element declares a message-driven bean. The declaration consists of:
- an optional description - an optional display name - an optional icon element that contains a small and a large icon file name. - a name assigned to the enterprise bean in the deployment descriptor - an optional mapped-name element that can be used to provide vendor-specific deployment information such as the physical jndi-name of destination from which this message-driven bean should consume. This element is not required to be supported by all implementations. Any use of this element is non-portable. - the message-driven bean's implementation class - an optional declaration of the bean's messaging type - an optional declaration of the bean's timeout method. - the optional message-driven bean's transaction management type. If it is not defined, it is defaulted to Container. - an optional declaration of the bean's message-destination-type - an optional declaration of the bean's message-destination-link - an optional declaration of the message-driven bean's activation configuration properties - an optional list of the message-driven bean class and/or superclass around-invoke methods. - an optional declaration of the bean's environment entries - an optional declaration of the bean's EJB references - an optional declaration of the bean's local EJB references - an optional declaration of the bean's web service references - an optional declaration of the security identity to be used for the execution of the bean's methods - an optional declaration of the bean's resource manager connection factory references - an optional declaration of the bean's resource environment references. - an optional declaration of the bean's message destination references
