JDK installation over pre-installed JRE?

R

rshri

Adept
My Windows XP PC already has JRE 1.6. I also have many applications installed that make use of this JRE. I would like to install JDK without re-writing the pre-installed JRE. Possible?

Also if I install Eclipse later, will it re-install JDK? I want to it to use pre-installed JDK/JRE.
 
You only have to change the install directory...jdk comes with its own jre and wont overwrite anything

all you need to do is check is the environment variables like jre_home and java_home stay the same after installation
 
No, if you are installing Eclipse, it will not install JDK. AFAIK Eclipse comes in zip file. Just extract and run. No need for installation.
