> Hi all,
>
> I am new to Tomcat/Apache, and have just about started to learn JSP/Servlets
> as well. I just wrote my first Hello world servlet (code below) and tried
> to run it, but got several errors. Here's exactly what I did:
> 1. I wrote "Hello.java" (code below) and put it in /webapps/ROOT directory
> 2. I tried to compile it ("javac Hello.java") but got errors. (see below)
>
> I would appreciate if someone would tell me what I am missing. Also, after
> the servlet compiles, do I need to put it in WEB-INF?
>
> Just for the records, I try to access the servlet using
> http://localhost:8080/Hello and I am using Java version 1.6.
>
> Thanks in advance.
