Hi,
I am always confused with this topic. I installed jdk1.3 with j2sdk-1_3_1-win.exe and set the CLASSPATH and PATH accordingly. However, I still need to install JAVA runtime env by running j2re1_3_0-win.exe to run some programs and some applets, even I saw the message like JRE setting up when I installed sdk.
Can anyone tell me what is the relationship between this JRE and SDK?
Thanks a lot
Chris

Chris,
The JDK contains the JRE. I cannot think why you need to install the 1.3.0 runtime instead of using the JDK 1.3.1 runtime.

To clarify it, I am using w2k. I set my path and classpath in control panel-system-environment.
path=c:/jdk1.3.1
classpath=.;c:/jdk1.3.1/bin
However, I do not know how I can use it jre.
