java.lang.ClassNotFoundException:org.apache.jasper.servlet.JspServlet

我试图在服务器上通过tomcat运行java应用程序，但一直收到此错误消息。我已尝试将正确的依赖项添加到pom.xml文件中，但似乎无法使其正常工作。我正在尝试使用heroku部署此应用程序

这是我的pom.xml文件中的依赖项：

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>
</dependency>

尝试添加org.apache.tomcat jasper 6.0.32我添加了它，但仍然是相同的错误尝试添加org.apache.tomcat jasper 6.0.32我添加了它，仍然是相同的错误
