as for your problem, maybe try setting the environment variables as instructed somewhere, i believe either in hf book or in the j2se's installation instructions(in same webpage where u downloaded the j2se)
my env variables for j2ee_home and java_home at that time are java_home=c:\j2sdk1.4.2_08 j2ee_home=c:\j2sdkee1.3.1
for PATH, i had PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;c:\j2sdk1.4.2_08\bin
Iam trying to download J2EE 1.3. My OS is XP professional. But I really unable to understand how to do? I followed this link http://java.sun.com/j2ee/1.3/download.html#sdk There are 3 options for download Sun ONE Application Server 7 1.3.1 FCS Release January 31, 2002 1.3 FCS Release September 17, 2001
I followed the link to Sun one Application server.
There I could see so many products. I really don't know what to download.
