[b]inka EAR - Enterprise Archive files [/b]--- anteee oka enterprise application anna mata which contain WARs , JARS and EJB files(Ivvi kuda JAR laa neee chestham)....... EAR only lives in App server ..... (nee old question diff between web server and app server ni induloo chusukooo)

[color=#FF0000][font=helvetica, arial, sans-serif][b]interface only define the behavior but not how the behavior implements ... sub-class of interface should implemente the behavior[/b][/font][/color]
