This artifact provides a single jar that contains all classes required to use remote Jakarta Enterprise Beans and Jakarta Messaging, including all dependencies. It is intended for use by those not using maven, maven users should just import the Jakarta Enterprise Beans and Jakarta Messaging BOM's instead (shaded JAR's cause lots of problems with maven, as it is very easy to inadvertently end up with different versions on classes on the class path).

There is a newer version: 35.0.0.Beta1

/**
 * The EJBMetaData interface allows a client to obtain the enterprise
 * Bean's meta-data information. 
 * 
 * The meta-data is intended for development tools used for building
 * applications that use deployed enterprise Beans, and for clients using
 * a scripting language to access the enterprise Bean. 
 * 
 * Note that the EJBMetaData is not a remote interface. The class that
 * implements this interface (this class is typically generated by container
 * tools) must be serializable, and must be a valid RMI/IDL value type.
