I attend a varitey of User groups and have good contacts in the Java world , as far as I know no one uses Whizlabs for screening/testing a candidate. PERIOD!. Certification is another matter , I think it carries values. Whilabs is a commercial product used to aid cerification aspirants and should be treated that way. In my company we have banned using any sort of commericial testing software for screening candidate.!
Whizlabs has demo/trial version has 10 questions , and is of no use. I guess atleast one exam should be given as trial( 60 questions) It is Not worth the time to install the whole thing for just 10 questions.
Wait for Head first . Their books are good,
I purchased the First edition of the book in November of last year(2003), and i want to give the certification now, I see that SCWCD 1.4 has come out and Hanumant & Jignesh are working on the 2nd edition of the SCWCD book . My question is that does some one know that if the authors intend to make the additional chapters( added chapters for 1.4 ) available as a soft copy , so that I need not purchase the new book? Does these authors have a e-mail where I can write to them.
Thanks very much,
Scalability is a performace matrix , it is the ability of a software program to continue to function smoothly as additional volume, or work is required of it. Also, o ne can say it is the ability to expand the number of users or increase the capabilities of a computing solution users without making major changes to the systems or application software.
To me, it is wrong to blankly say that Stateful beans are not scalable. I think it should say "less scalable" rather than "not scalable" . Yes they have more overhead than the stateless beans, but sateful beans are there for a purpose , to maintain state between method invocations.
It would be a overkill if one uses stateful bean for a business rule when the same thing can be done with a stateless bean.
Reg. examples, it is hard to give you a example for scalability as one can experience when the system is under load testing or under peak load.
if you would really like a example , then you could download one of the free load testing tools and run them against your application.
I am not sure if this is what you were looking for :
If you have the names of the request parameters that match the name of the Javabean property then there is a shortcut to set all the properties of a bean in a single action.
<jps:setProperty name ="XXXX" property ="*" />
where XXXX is the id of teh Javabean.
I don't understand your question completly , but if you looking at only one instance of the class ,then "SINGLETON" pattern is something which you might want to consider.
Please refer to the following link , see under Mock Exams

I am not sure if this is the right forum for this , I did not find any suitable area to post this message thus posting it here. I saw earlier posts that they were giving away free copies from Whizlabs and Enthuware. If anyone willing to donate their exam simulator if they are done with the certification and have no use for it. I will pick up the shipping costs.
My e-mail id is anonymous_student_us@yahoo.com
Thanks!

Mock exams under the JavaRanch SCWCD Links (http://www.javaranch.com/scwcdlinks.jsp) page do not work, anyone has the new links to these mock exams.
Thanks!
We are using IBM's visual Age 3.5 ( Which follows EJB 1.0 specifications) for Java for Windows version 3.5 and Oracle 8i for development of a web Appication involving Container managed Entity Beans.
I have a finder method
public java.util.Enumeration findFirstNSamplesOrderByDate (java.lang.String modelInstanceId, int nSamples)
throws java.rmi.RemoteException,javax.ejb.FinderException;
}
I have made the following declaration in the HelperInterface
public java.sql.PreparedStatement findFirstNSamplesOrderByDate(String modelInstanceId, int nSamples) throws java.rmi.RemoteException, javax.ejb.FinderException;

I do not know how to test this in Visual age for Java test Environment
First of all sorry for the multiple posts , but all of a sudden no one is responding to my question thus these multiple posts in various categories.
Is there a way to find out in java , when a user leaves the current domain and goes to another domain by typing another URL in address field of browser.
e.g.
if i am at www.yahoo.com and if i type www.hotmail.com in the address bar.
Can I track the domain of the newer site i.e. www.hotmail.com this is only needed if the user is changing the domain through the Address bar in Internet Explorer or Location bar in Netscape.
I have tried location.hostname in javascript and it is giving me www.yahoo.com i.e. the current hostname but i could not access the www.hotmail.com ie. the new URL.
Is there a java solution for this either through invisible applets or invisible servlets, or any java function I use in a JSP , servlet etc.
Any solution in any software is ok.
Thanks for your time and help
Thanks
