hi gaiser,

1) As new versions release, there is differences in performance. One significant point to note is the JVM versions that are supported which significantly impact the application server performance. The new WLS 8.1 on the newest released 1.4.2 JVM is damn good.

2) Yes, we can declare ourown exceptions by using throw statement..

just go through this code

All methods use the throw statement to throw an exception. he throw statement requires a single argument: a throwable object. Throwable objects are instances of any subclass of the Throwable class. Here's an example of a throw statement.

throw someThrowableObject;

Let's look at the throw statement in context. The following pop method is taken from a class that implements a common stack object. The method removes the top element from the stack and returns the object.

public Object pop() throws EmptyStackException {

Object obj; if (size == 0) { throw new EmptyStackException(); } obj = objectAt(SIZE - 1); setObjectAt(SIZE - 1, null); size--; return obj;
