I am having the same problem...
I'm on a Windows XP system with jdk1.5.0_04 installed. I used the installer versions of XAMPP Windows 1.4.15 (xampp-win32-1.4.15-installer.exe) and Tomcat 5.5.9 (xampp-tomcat-addon-5.5.9-installer.exe).
I'm also using Mozilla Firefox 1.0.6 (although the same error occurs with Internet Explorer).
Going to
http://localhost:8080/ and clicking on the Tomcat manager link (in the Administration box) results in the information shown below (after authenticating using user xampp and password xampp)...
Does anyone have any suggestions for a fix? Any information would be most appreciated!
Cheers!
