How to properly setup jdk7, jre6,jre7

I need to setup jre6, jre7, jdk7 under my C:\PFiles\metadev\java folder.But I am confused at some points.I have 3 setup files, which are named jdk-6u29-windows-x64, jdk-6u31-windows-x64,jdk-7u3-windows-x64.Also, I have an word document which explains me how to properly setup eclipse and jdk/jre stuff.I have put eclipse under C:\PFiles\metadev.That's OK.Then, in the word document it says that I should put a folder named java, which has already included jdk1.6.0_29, with the following content:

    jdk1.6.0_29
-bin
-demo
-include
-jre
-lib
-sample
-COPYRIGHT
-LICENCE
-README
-register
-register_ja
-register_zh_CN
-src(zip file)
-THIRDPARTYLICENSEREADME

After placing java folder, with jdk1.6.0_29, under C:\PFiles\metadev\; the word document says that I should setup jre6, jdk7 and jre7.

Here are the points where I am confused: Does jdk1.6.0_29 stands for jdk 6? Also what does jdk-6u29-windows-x64, jdk-6u31-windows-x64,jdk-7u3-windows-x64 setup files represent(in terms of jdk6, jdk7 etc..)? I have also thought that jre is automatically comes when I setup jdk.Should I setup jdk and jre separately?

Thanks for any help.

Solution

  • jdk1.6.0_29 is jdk6u29

    jdk is java development kit which includes jre which is java runtime environment.

    If you install jdk-7u3-windows-x64 you should have what you need.
