Need help to start preparation for scdjws exam

hello everyone,

I am planning for SCDJWS exam. So I ended up with two books for theory and practicals both.
1. Developing_Java_Web_Services_-_Wiley Publishing
2. J2EE Web Services: XML SOAP WSDL UDDI WS-I JAX-RPC JAXR SAAJ JAXP

I have also have Study Notes-Ivan A Krizsan , this book is very good for the exam, but after going through the book I found this book have much on practical and I am new in web services and never worked in this. So decided to read it after reading anyone from above books.

please help me in choosing the right book and also suggest other books as well.

thanks

Cleared SCJP 1.6 with 83%

hello friends,

Thank alot to all of your support, suggestions and the right directions for preparation I got from all of you...
I had completed kathy and khalid 2-3 times both of the books ...before going for mock questions..
then I did practised all kind of question form easy to tough ones..
here on javarach I find Niko's topic wise practise questions are really good ..then i completed the specific question for scjp1.6..
after that i started ExamLab mocks for 1.6(here i got 50%-65%).

I feel little sad when i got my score card in my hands that I got only 83% because i was expecting atleast 90+

...thanks again to Javaranch ..its such a great community that helps a lot...It helped me to clear all of my Java doubts even if its a silliest one.

Wish you Best of Luck for those who are preparing for this exam.

Question from JavaChamp.com Mock Exam

Ques:

Answer : The code compiles fine but throws a RuntimeException because of the second casting

Vehicle is Colorable, both exist in same inheritence tree. so base-class can hold its sub-class object. then why this code gives exception for second casting. Please give explaination. And if possible also provide theory/link for this concept so i can know more in depth of this concept.

Final methods

yes you can have final methods in abstract class
try this code
abstract class abstractclass
{
final public void display(){
System.out.println("Display");
}
abstract void show();
}
public class extendedclass extends abstractclass{
public static void main(String args[]){
array aa = new array();
aa.display();
aa.show();
}
public void show(){
System.out.println("show");
}
}
