Hi, I know this question is not about the certificate exam, but I still hope you could help me out.
I am trying to install Oracle JDeveloper on my machine, and it requires a JDK be installed first, I have sdk1.4.0 installed already, should I download another JDK?
Thanks a lot!

Hello Jan Bai,
I don't think you need to download another JDK if you already have 1.4.0.
However you will need to set the variable SetJavaHome in the file <jdev_install>\jdev\bin\jdev.conf to the location of your JDK installation. Use an editor that recognizes UNIX end-of-line characters, such as WordPad. When you save the file, WordPad will warn you that it is about to save the file in text-only format. You can ignore this warning.
For example, in a Windows environment, if the location of your JDK 1.3.1_02 is in a directory called jdk1.3 on your D drive, your entry in jdev.conf would look like:
SetJavaHome d:\jdk1.3

Peter, Thanks.
Oracle provides alink to download JDK1.3.1_02, but this webpage doesn't have JDK version higher than 1.2.1, while SDK has the very new release.
Is JDK functioning as a graphic develop environment? Is it only one component of SDK - but it seems not, since I couldn't find anything about it in the java directory.

JDK stands for Java Development Kit.
SDK stands for Software Development Kit.
Sun used to call the software development kit that it provided for Java programming "The JDK". Since, 1.3 or 1.2, Sun wants everybody to call it "The Java SDK".
