I have this HelloWorldExample in my local Tomcat server.
It shows as a web page as it should with the words "Hello World!". For my first Servlet I wanted to compile it but it gives me errors and doesnt work.
Here is my attempt:
C:\jakarta-tomcat-4.1.27\webapps\examples\WEBINF\classes>javac HelloWorldExampl
e.java
Here is the Java file:
My Error messages:
HelloWorldExample.java:8: package javax.servlet does not exist
import javax.servlet.*;
^
HelloWorldExample.java:9: package javax.servlet.http does not exist
import javax.servlet.http.*;
^
HelloWorldExample.java:17: cannot resolve symbol
symbol : class HttpServlet
location: class HelloWorldExample
public class HelloWorldExample extends HttpServlet {
^
HelloWorldExample.java:20: cannot resolve symbol
symbol : class HttpServletRequest
location: class HelloWorldExample
public void doGet(HttpServletRequest request,
^
HelloWorldExample.java:21: cannot resolve symbol
symbol : class HttpServletResponse
location: class HelloWorldExample
HttpServletResponse response)
^
HelloWorldExample.java:22: cannot resolve symbol
symbol : class ServletException
location: class HelloWorldExample
throws IOException, ServletException
^
Please advise why I cant get this servlet to compile? It says I dont have the packages so I assume it was compiled somewhere else?
