The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path

"The superclass 'javax.servlet.http.HttpServlet' was not found on the Java Build Path"是一个常见的错误，通常在使用Eclipse开发Web应用程序时出现。这个错误的意思是在Java Build Path中找不到javax.servlet.http.HttpServlet基类。这个错误通常是由于缺少Web容器的依赖库或配置不正确引起的。

解决方法一：在pom.xml中配置依赖项，以确保Web容器的依赖库被正确地添加到项目中。

解决方法二：手动将Web容器的依赖库添加到项目中。在Eclipse中，可以通过右键单击项目，选择“Properties”，然后选择“Java Build Path”选项卡，在“Libraries”选项卡下添加所需的库。

解决方法三：检查项目的部署描述符(web.xml)是否正确配置。确保servlet类在web.xml中正确地映射到URL模式。

This error typically occurs when a required library or dependency is missing from your project's build path. To resolve this issue, you can try the following steps:

1. Check if the required library (in this case, javax.servlet.http.HttpServlet) is present in your project's build path. If not, add it to your project's build path.

2. Ensure that the library is located in the correct directory and that the directory is included in the CLASSPATH environment variable.

3. Refresh your project's build path by right-clicking on the project and selecting "Refresh" or by pressing F5.

4. If you're using an IDE like Eclipse or IntelliJ, try cleaning and rebuilding your project.

If none of these steps work, you may need to investigate further to determine the root cause of the issue.
