I just want to make sure about what I have read about setting up Tomcat on the Windows - XP. 1. There is an advice on that %PATH% is not necessary. 2. do not use trailing semicolon. 3. use lower cases. Please kindly confirm the following: when set path variable: click on My Computer-->Properties-->Advanced-->Environmental Variables. Click on lower panes New button and in the text field variable: I typed PATH and in the text field of value: I typed C:\j2sdk1.4.1_02\bin;%PATH%; Do the advices mean that in the text field of value: I should instead type c:\j2sdk1.4.1_02\bin And when set environmental CLASSPATH variable, I should type c:\j2sdk1.4.1_02\lib\tools.jar;c:\j2sdk1.4.1_02\lib;c:\j2sdk1.4.1_02\servlet.jar in the text field of value?
