Classpath problem

[J JAR]

I have the same problem in this post:
http://www.coderanch.com/t/171071/java-Web-Component-SCWCD/certification/classpath-help-examples

I get a "package javax.servlet does not exist" error when I try to use -classpath to specify the servlet-api.jar file in the Tomcat\common\lib directory. And yes...I can get the servlet to compile by adding setting the CLASSPATH environment variable in Windows....but I should still be able to compile this by using the -classpath option, right? Does anyone know what I'm doing wrong? Here is my source:

package com.example.web;

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;

public class BeerSelect extends HttpServlet{
public void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("Beer Selection Advice<br>");
String c = request.getParameter("color");
out.println("<br>Got beer color " + c);
}
}

Here is the path to servlet-api.jar:
C:\Tomcat\common\lib

Here is what I'm entering with the first couple of errors that get generated:

C:\Data\Java\WebProjects\beerV1>javac -classpath C:\Tomcat\common\lib\servlet-api.jar:classes:. -d classes src\com\example\web\BeerSelect.java
src\com\example\web\BeerSelect.java:3: package javax.servlet does not exist
import javax.servlet.*;
^
src\com\example\web\BeerSelect.java:4: package javax.servlet.http does not exist

import javax.servlet.http.*;
^
src\com\example\web\BeerSelect.java:7: cannot find symbol
symbol: class HttpServlet
public class BeerSelect extends HttpServlet{


I'm sure it's just something stupid that I can't see. Please help!!!

Thanks!

Nevermind. The problem was using colons in my classpath instead of semicolons.

Duh.

Thanks anyways.
