Are there any sites where I can get promotion vouchers for SCJP? I got some promotion code for my Oracle Certification exam from somewhere. Did any one use such vouchers to take SCJP?
Any information is highly appreciated.
Thanks,
V

While doing some examples in Marcus Green's site I have encountered this one.

class Base {
int i=99;
public void amethod(){
System.out.println("Base.amethod()");
}
Base(){
amethod();
}
}
public class RType extends Base{
int i=-1;
public static void main(String argv[]){
Base b = new RType();
System.out.println(b.i);
b.amethod();
}
public void amethod(){
System.out.println("RType.amethod()");
}
}

When I ran this I thought(Even Green said) the output would be
RType.amethod
99
RType.amethod
But the output I got on my machine is
99
Base.amethod
Any clues?

P.S: I have JDK 1.3.1. on my machine.

Thinking in java is the best. I read core java along with it, but its size made me feel nervous( its so heavy , I had to lie down on my side and keep it on the bed to read it ).Since TIJ is free, I recommend downloading it. Hope this helps.

Rahul,
Where did you get the book? Can you give me the link? Thanks, I will appreciate it.

Yes. It started working when I put it under the ext directory. Thanks Hardy.

Sean,
Thanks. I downloaded the servlet jar file into my jdk/bin directory. When I tried to compile after that, I am still getting the same error. What could have gobe wrong? Because I have downloaded it to the jdk/bin which is already there in the class path, I didnt have to edit the classpath.

Hi,
This is kinda basic, I would appreciate if someone cares to answer this... I tried to compile a servlet. I have not downloaded servlets api. So the compiler gave an error saying javax.servlets and servlets.http packages dont exist. Now where should I download the javax.servlets and javax.servlets.http to? Into the same directory where my jdk is there?

Where should I download the servlets package to?

Tim, the whole point is that - that i have cleared the exam without doing any coding.
Jane, i got it. i was adding the bin directory in classpath in autoexec.bat. i got it when i added it in the path. Now that I know how to do it, it looks so simple and basic. Tim, I am not surprised that you are annoyed.
Jane and others, be ready to answer my doubts in jdbc, servlets, jsp and possibly ejbs. I love this place. How did I miss this before?

------------------
Sun certified , with the lowest score possible.

no, jane, this is not about the websphere. i have downloaded jdk1.4 separately. i need servelet class files to be deployed in websphere.i can do it in visualage and then export from there, but i want to do it the rudimentary way.

Jane and Greg, I was trying to compile a servlet from the jdk/bin directory and it is giving errors saying javax.servlets package doesnt exist. Looks like I have to download servlets package separately. Right? If so, where from from sun site? And if I want to compile my servlets into class files ( which are then to be deployed in websphere app server) where should I download this javax package to? To the same directory where my jdk is there? I would appreciate if you can answer my above question and this together.

Thanks Jane and Greg, It worked. I am able to compile from jdk1.4/bin using javac filename. but once compiled, I am not able to run it . I am able to run only by physically moving the file to the bin directory. For example,
C:\jdk1.4\bin: javac c:\someDir\Somefile.java works.
c:\jdk1.4\bin: java c:\someDir\Somefile doesnt.
I have to move Somefile from someDir to jdk1.4\bin compile there and then run from this directory (jdk14/bin). Where am I amiss?
