need basic help to compile first servelet

[neetika sharma]

Hello,
I have installed jakarta-tomcat-5.5.9 on Windows XP OS.
I am following HFSJ for reference.While comiling the simple servlet as mentioned in chapter-3, i am getting loads of compilation errors as.......

I have checked that servlet-jar file is present in proper path (c:/jakarta-tomcat-5.5.9/common/lib/servlet-api.jar)

C:\Documents and Settings\neetika\Desktop\MyProject\beerV1>javac -classpath c:/jakarta-tomcat-5.5.9/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 {

src/com/example/web/BeerSelect.java:9: cannot find symbol

location: class com.example.web.BeerSelect
public void doPost( HttpServletRequest request, HttpServletResponse resp
onse) throws IOException, ServletException {

public void doPost( HttpServletRequest request, HttpServletResponse resp
onse) throws IOException, ServletException {

If I set the classpath from cmd prompt as......

C:\Documents and Settings\neetika\Desktop\MyProject\beerV1>set CLASSPATH=.;C:\jakarta-tomcat-5.5.9\common\lib\servlet-api.jar

and then simply giving

C:\Documents and Settings\neetika\Desktop\MyProject\beerV1>javac src/com/example/web/BeerSelect.java

then it is compiling.Can Anybody explain me this unexpected behaviour.Y is this not working with -classpath option during compilation.

You'll probably get better help with classpath and javac questions in the Java In General (Beginner) forum so.... moving.

I did not get , how this is related to my query. Do you want to say that whatever compilation errors I am getting is because of colon used??? But this is same as given in HFSJ. Kindly clarify

With your classpath as it is, the compiler is looking for a file or directory called
c:/jakarta-tomcat-5.5.9/common/lib/servlet-api.jar:classes:.
i.e. it thinks that it is a single file name because there are no separators

If you change it to
c:/jakarta-tomcat-5.5.9/common/lib/servlet-api.jar;classes;.
then the compiler will look for a file called c:/jakarta-tomcat-5.5.9/common/lib/servlet-api.jar and will look for classes in the 'classes' directory and the current directory.

The example in the HSFJ was probably written for use on Unix where the separator is a :
