Hi ranchers.......

Happy to share this news with u all. I cleared SCWCD 1.4 with 81%. I really feel very relaxed.

Thanks for HFSJ authors for a wonderfull book. It is a great book and that helped me clear it. The Final mock test of HFS is really very hard. Taking up the test after taking up the HFS final mock made me feel that the real exam is much more easier.

I used the enthuware software which is almost very close to the real exam questions.

HFSJ and enthuware + working out on machine and analzing the results will help to get through the exam very easily

Thanks for the ranchers for their support.. Thank u very much

Hi all...

when a getSession of HttpSessionEvent is called in a HttpSessionListener when a session is invalidated will return the session that is changed but will that session be still a invalidated session or a valid session.
Can any one give a proper explanation for this question.
... wat will happen when a session is invalidated..

public class MyHttpSessionListener implements HttpSessionListener
{
public void sessionCreated (HttpSessionEvent e)
{
System.out.log ("Session Created");
}

public void sessionDestroyed (HttpSessionEvent e)
{
HttpSession session = e.getSession ();
String name = (String) session.getAttribute ("username");
}
}
Which of the following statements best describes the code?
� A) A compilation error will occur as the HttpSessionListener class is not properly implemented
� B) No errors or exceptions will occur as the code is written correctly
� C) An IllegalStateException will be thrown when the code is executed
� D) None of the above


The answer is given as c. and the explanation is given as
�The HttpSessionListener interface only defines the sessionCreated () and sessionDestroyed () method calls.

Hence, the code properly implements the interface correctly. So a compilation error should NOT occur.

However, at code execution, an IllegalStateException will be thrown when the session.getAttribute ("name") is called.

By the time the servlet container calls the sessionDestroyed () method, the session has already been invalidated. Therefore a call to getAttribute () will throw an IllegalStateException

but my doubt is e.getSession() will return the session tat is changed. so why cant it call the getAttribute ovet that session.


can any one help me

SCJP 1.4
Hi ranchers

Do all these following 3 options mean the same of different.

1. <jsp:getProperty property="streetName" name="id"></jsp:getProperty>

2. <jsp:getProperty name="id" property="streetName"/>

3. <jsp:getProperty property="streetName" name="id"/>

Is that neccessary that jsp:getProperty should be a self closing tag.
