Hi,
  I created my own aplication(myApp) under webapps,I put all my own classes under /myApp/WEB-INF/classes.It works fine
  I want to put my classes in order.So I created two folders /myApp/WEB-INF/classes/myPackageA and /myApp/WEB-INF/classes/myPackageB
  How can one class(A.java) under /myApp/WEB-INF/classes/myPackageA use other class (First.java) under /myApp/WEB-INF/classes
  or (B.java) /myApp/WEB-INF/classes/myPackageB? I put "package myPackageA;" in the first line of A.java and
"package myPackageB;" in the first line of B.java.It doesn't work.
How these these classes(First.java,A.java, B.java) can use each other?
Thanks Dennis

I believe you could just import them.
