问题 I am trying to create an EAR file from the command prompt. I have used jar -cvf myServletWAR.ear . But my question is, how can I get this EAR file to have WAR files and JAR files inside it? Do I need to create the war file separately and include in the ear file?

问题 I know Stateless EJBs are stored in a pool and instantiated as needed, my question is, what happens when there are more EJB dependencies, for example with something like this: @Remote @Stateless public class Master_EJB{ @EJB private EJB_A ejb_A; @EJB private EJB_B ejb_B; } With EJB_A and EJB_B also being stateless EJBs.

I already added enctype="multipart/form-data" as mentioned here but now it is always recognizing email as null and I can't forward to the login page in case of success (when email is not null).
