Please help with bean package problem - serlvet can't find package

Question

Hi,
I'm fairly new to java web development, and I can't make any good learning progress due to an error I just can't seen to fix. It seems humiliatingly trivial, but I can't get past it.
Explanation:
I'm experimenting with beans, and I've created a very simple servlet called AppSetup to create a LinkBean instance and store it in the servlet context for later retrieval. My problem is that the servlet wont compile because it's telling me the package in which the LinkBean class file is in doesn't exist.
The servlet is in package org, and the bean is in package org.bean. This is the import statement in the servlet:
Code:
import org.bean.*;I've also tried:
Code:
import org.bean.LinkBean;and
Code:
import bean.*;I've tried all sorts of different package structures, but I get the same following error for all of them:
Quote:
C:\tomcat\webapps\chub\WEB-INF\classes\org>javac AppSetup.java
AppSetup.java:14: package org.bean does not exist
import org.bean.*;
^
AppSetup.java:19: cannot find symbol
symbol : class LinkBean
location: class org.AppSetup
LinkBean lb;
^
AppSetup.java:23: cannot find symbol
symbol : class LinkBean
location: class org.AppSetup
lb = new LinkBean();
^
3 errors
edit
Server is Tomcat 5.5
Any help would be greatly appriciated. Thanks.

The bean class has to be in the classpath. The classpath variable informs the compiler\jvm where to find the .class files that are being referred.
To set a classpath,
javac -classpath C:\tomcat\webapps\chub\WEB-INF\classes;C:\tomcat\webapps\chub\WEB-INF\lib;C:\tomcat\common\lib;.; AppSetup.javaThere are 3 paths in the classpath variable above.
1.\WEB-INF\classes => Your class files
2. \WEB-INF\lib => Your app library files (.jar files)
3. \common\lib => common library .jar files
4 The dot (.) => current directory.
