I am trying to build a serializable javabean.
What can I do with inputstream? Should I always read the whole stream and
put that into a byte[] attribute? This doesn't seem a good solution.
What else could I do?

Dear Sir/Madam,
  I started learning J2EE recently and I tried to run converter
application in the j2ee server, but i got struck at the following
point.

The Subject says its all.
java.util.Calendar and java.util.GreGorianCalendar
can let me find out New Moon, Full Moon.
