编译servlet出错，帮助啊！（好像是找不到包的问题）

Test.java源代码如下：
package test;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class Test extends HttpServlet {
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
PrintWriter out=response.getWriter();
out.println("<html><body><h1>This is a servlet test.</h1></body></html>");
out.flush();
}
}

编译错误如下：
E:\tomdep\WEB-INF\classes\test>javac Test.java
Test.java:4: package javax.servlet does not exist
import javax.servlet.ServletException;
                  ^

已解决，把servlet-api.jar(tomcat中含有这个包）加入到CLASSPATH中就可以了。

我的CLASSPATH如下设置就可以了：
E:\tomdep\WEB-INF\classes\test>echo %classpath%
.;C:\Borland\JBuilder2005\jdk1.4\lib;C:\Borland\JBuilder2005\jdk1.4\jre\lib;C:\B
orland\JBuilder2005\thirdparty\jakarta-tomcat-5.0.27\common\lib\servlet-api.jar
可是我很奇怪，为什么设置CLASSPATH为...\lib\（即servlet-api.jar所在的路径，而不是本类包）就不可以了呢？
