help me solve 'package javax.servlet does not exist' error

[srinivas pola]

Hi,

I am using tomcat6 and jdk1.5
I am not using any IDE and trying to compile the servlets through command prompt itself.

The environment variables i have set are as follows:
CLASS_PATH - C:\jdk1.5\lib;C:\tomcat6\lib\servlet-api.jar;C:\tomcat6\lib\jsp-api.jar;C:\tomcat6\webapps
JAVA_HOME - C:\jdk1.5
Path - C:\jdk1.5\bin;C:\jdk1.5;C:\jdk1.5\jre\bin\server

When i'm trying to compile the servlet i'm getting this error

C:\tomcat6\webapps\HeadFirst\WEB-INF\classes\web>javac BeerSelectAction.java
BeerSelectAction.java:3: package javax.servlet does not exist
import javax.servlet.*;
^
BeerSelectAction.java:4: package javax.servlet.http does not exist
import javax.servlet.http.*;
^
BeerSelectAction.java:7: cannot find symbol
symbol: class HttpServlet
public class BeerSelectAction extends HttpServlet {
^
BeerSelectAction.java:9: cannot find symbol
symbol : class HttpServletRequest
location: class com.example.web.BeerSelectAction
public void doPost(HttpServletRequest request,
^
BeerSelectAction.java:10: cannot find symbol
symbol : class HttpServletResponse


Please help me solve this error.

Thanks in advance.

The error is here:

CLASS_PATH - C:\jdk1.5\lib;C:\tomcat6\lib\servlet-api.jar;C:\tomcat6\lib\jsp-api.jar;C:\tomcat6\webapps

The environment variable should be named CLASSPATH, not CLASS_PATH with an underscore in it.

Just a lucky guess..

try web.BeerSelectAction instead of classes.web.BeerSelectAction in servlet-class

What I am thinking of here is that the package of your servlet class should not include the .....\WEB-INF\classes folder..

[srinivas pola]

I have tried by removing 'classes' from the servlet-name. But i'm still facing the same problem...

Please help me out...

[Ulf Dittmer]

Do you have a "package web;" statement in the source code that you didn't post? If not, then the servlet-class will just be "BeerSelectAction".

[srinivas pola]

yes i have a web folder inside classes...

its like WEB-INF\classes\web\BeerSelectAction.java

[Ulf Dittmer]

So the answer to the question "Do you have a 'package web;' statement in the source code that you didn't post?" is "yes"?

[srinivas pola]

Yaa.. The servlet is in 'web' folder

Looks like you are not getting what Ulf has asked.
He means : Do you have any statement like

[B]package web;[/B]
//import list
//class definitions go here

in your code for the servlet.

And please use code tags while posting code, unformatted code is not only difficult to read, but also results in less response for your post. Read this for more information.

I hadn't noticed, but now somebody has mentioned it, I am closing this thread as a duplicate.
