compiler error - package javax.servlet does not exists

[Varalakshmi Ramanarayan]

Hello ranchers!!
I have just started preperation for SCWCD, with HFJS. I am in the 3rd chapter, and am trying to build the servlet app in explained in that chapter. But I am getting errors like

package javax.servlet doesnot exist
package javax.servlet.http doesnot exist 
cannot find symbol--> HttpServlet

I have tried hours and hours finding the solution for this, but in vein. I tried to change the classpath settings, environmental variable settings. nothing worked. Can someone please let me know the cause and solution for this error?
currently, I am using Tomcat 5.5, and I have set environment variables as below(in my case)

set JAVA_HOME=C:\Program Files\Java\jdk1.5.0_13
set TOMCAT_HOME=C:\Varu\WEBJavaLearning\tomcat

and javac comand as below

c:\varu\WEBJavaLearning>javac -classpath tomcat\common\lib\servlet-api.jar:classes:. -d classes BeerV1\src\com\example\web\BeerSelect.java

What am I missing? hoping for help!!
Thanks a lot in advance.

Replace colons by semi-colons at the command line :
-classpath %TOMCAT_HOME%\common\lib\servlet-api.jar;classes;.

Thanks very much Christophe..
It worked..
How could I overlook that..

My Goodness! I got the same problem and spent two days to try to solve the problem. Now I know colons ":" are used in Unix/Linux, but semi-colons ";" are used in Windows. The book did not tell me the difference. So I was totally confused.
Thanks a lot for helping me with the answer.

I tried replacing the colons with semicolons, but I am still getting the same error message.

Please show us your command line. Did you set the TOMCAT_HOME variable (type echo %TOMCAT_HOME%)?

Hi,
I am also facing the same problem. I am using this command and its throwing me an expection

package javax.servlet does not exists.

javac -classpath C:\Program~\Apache~\Tomcat~\common\lib\servlet-api.jar;classes;. -d classes src\com\example\web\BeerSelect.java

Can some please tell me where I am going wrong.

Thanks in advance

throwing me an expection

A compilation error, not an exception

What are these "~" ? Try to enclose the whole classpath with double quotes :
javac -classpath "C:\Program~\Apache~\Tomcat~\common\lib\servlet-api.jar;classes;." -d classes src\com\example\web\BeerSelect.java
