我正在使用Eclipse开发一个Java Web应用程序,使用Servlet进行测试,并在我的本地主机上使用Tomcat服务器进行测试。我已经将应用程序部署到Tomcat中,但当我尝试在浏览器中加载目标URL时,我收到以下堆栈跟踪:

ImageServlet类明显位于我的Eclipse工作空间中的myproject/src/test文件夹中,其中myproject是Eclipse项目的名称,test是包名。
web.xml位于myproject/web/WEB-INF/web.xml,而myproject.xml位于myproject/myproject.xml。
web.xml的内容如下:
<?xml version="1.0"?>
<web-app
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
<servlet>
<servlet-name>ImageServlet</servlet-name>
<servlet-class>test.ImageServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ImageServlet</servlet-name>
<url-pattern>/image</url-pattern>
</servlet-mapping>
</web-app>
我的project.xml文件内容如下:
请问有谁能向我展示如何修复我的代码,以便它不会抛出ClassNotFoundException异常?
