Hi i'm busy doing a project that requires as to use Message-Driven Beans so far i have had no problem in creating the Beans but when it come to using them in my servlet i get the following error: javax.annotation.Resource.authentication Type()Javax/annotation/Resource$AuthenticationType;at com.sun.enterprise.deployment.annotation.AnnotationInfo@ba356 .

The code i am using in the servlet is as follows:

package web2;

The code for the message driven bean is from a book provided to me. I am very new to J2EE and do not know what the error is refering to. If anyone can either tell me what the error means or a way to stop netbeans throwing the abovementioned error i would really appreciate it.
