我已经将TomEE与Eclipse一起安装，以便开始开发动态Web项目（我对此还不太熟悉）。
在将项目添加到TomEE服务器之前，我可以毫无问题地启动它。
但是当我将项目添加到服务器并尝试运行它时，我会收到错误消息：java.lang.IllegalArgumentException: Unsupported class file major version 58
为了解决这个问题我尝试了以下方法：
- 更改服务器端口号
- 删除并重新创建服务器
- 检查
web.xml文件以确保servlet映射正确 - 重新配置项目的目标运行时
- 重新配置Eclipse的运行环境
版本：
- TomEE：v8.0.3 plume
- JDK：15.0.1
- Eclipse：4.17.0
测试项目代码
TestServlet.java
package my.test.project;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class TestServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/plain");
PrintWriter out = response.getWriter();
out.println("Hello this is a test");
out.close();
}
}
Web.xml
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"

执行后在控制台日志中出现错误

谢谢。
