All those JSP samples in the ...\webapps\examples directory worked
without any problem. I always get error-404 when I run my own
But, why my little Hello.jsp in the ...\webapps\Root directory gives me error-404 when I typed http://localhost:8080/Hello.jsp in the IE address bar?
Check the directory and make sure that the jsp landed in the same directory as the default Tomcat index file.
Is the capitalization of your directories and the jsp file consistent with the url? Even if you're working on a windows platform, it could matter.
