.java won't compile

**paul21** · 03-29-2010, 06:11 PM

I'm having trouble getting a simple .java to compile

Java Code:

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

public class HelloWorld extends HttpServlet {
  public void doGet(HttpServletRequest request,
                    HttpServletResponse response)
      throws ServletException, IOException {
    response.setContentType("text/html");
    PrintWriter out = response.getWriter();
    out.println( "<HTML> <BODY> <H1>Hello World !</H1> </BODY></HTML>");
  }
}

here are the error

Java Code:

paul@paul-laptop:~$ javac -cp . HelloWorld.java 
HelloWorld.java:2: package javax.servlet does not exist
import javax.servlet.*;
^
HelloWorld.java:3: package javax.servlet.http does not exist
import javax.servlet.http.*;
^
HelloWorld.java:5: cannot find symbol
symbol: class HttpServlet
public class HelloWorld extends HttpServlet {
                                ^
HelloWorld.java:6: cannot find symbol
symbol  : class HttpServletRequest
location: class HelloWorld
  public void doGet(HttpServletRequest request,
                    ^
HelloWorld.java:7: cannot find symbol
symbol  : class HttpServletResponse
location: class HelloWorld
                    HttpServletResponse response)
                    ^
HelloWorld.java:8: cannot find symbol
symbol  : class ServletException
location: class HelloWorld
      throws ServletException, IOException {
             ^
6 errors

here is the classpath location

Java Code:

paul@paul-laptop:~$ echo $CLASSPATH
/home/paul/apache-tomcat-6.0.18/lib/servlet-api.jar:/home/paul/apache-tomcat-6.0.18/lib/jsp-api.jar

any ideas why this will not compile

solved

I used

Java Code:

javac

when before i was using

Java Code:

 javac -cp . HelloWorld.java

Anyone any idea why it wansn't working to begin with as javac -cp . should work

The -cp option overrides the CLASSPATH environment variable. When you did '-cp .' you wiped out the Tomcat directories in your CLASSPATH.

i will advice you to go and download netbeans with web application to be able to run your servlets

hi,
you has to compile with the jar file with -cp option
like this
C:\Documents and Settings\Desktop>javac -cp "D:/samples/javax.servlet.jar" HelloWorld.java
this is windows i dont know how the same doing in linus based patforms
ok

you will get the jar from http://www.java2s.com/Code/Jar/STUVW...servletjar.htm
