I resently installed xampp using the installer
I installed Java 1.6
I tried to install the tomcat add-on using the tomcat installer but it spat out an error saying can't find Java 1.5
I successfully installed tomcat using the .zip by modifing one char in one file.
Extract the tomcat .zip file to your example directory.
goto line 156 column 78
replace 1.5 with 1.6
HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit\1.5\JavaHome
HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit\1.6\JavaHome
Start topcat with the tomcat_start.bat you should be able to access tomcat on
So far so good I've had it running for one day
