Hi, Senthil.
if you don't set initial values for fields you declare, they are
initialized as mentioned
in java specification. you can check at
http://java.sun.com/docs/books/jls/third_edition/html/typesValues.html#4.12.5
so,
long productId;
long productId = 0;
are the same.
String abc;
String abc = null;
are the same.
these are not struts specifc.
are you talking about anything struts-specific thing such as ActionForm?
regards
ichy
