You mean the jar files containing javax.ejb.* package? When you download JBoss, it already comes with these jar files (which you can find in %JBOSS_HOME%/server/default/lib folder).

How can I deploy a whole application including servlets and EJBs into jboss?
You can create an EAR file containing the ejb jars and the servlet/jsp war file and place the ear file in the deploy folder of JBoss.

Can we deploy them as separately, as the servlets and JSP packeged into test.war and the EJB stuff packaged into test.jar?
Yes, you can deploy it this way too
