Java NetBeans中的Tomcat在停止或重新启动服务器时出错（“停止Tomcat失败”）

每次我停止或重新启动

NetBeans（Services>Servers）

中的

tomcat

服务器时，都会花费很长的时间，并且会发出错误消息，如停止tomcat失败。。这个问题有什么解决办法吗

您在哪个端口上运行Tomcat？因此您使用的是默认端口。能否尝试更改端口号并查看其是否工作？能否共享控制台异常详细信息。此外，请参阅此链接，它可能会有所帮助。Subbarddy Nalamachu：我已经用服务器日志详细信息更新了帖子。谢谢你的链接。但是仅仅停止服务器的问题。Abhiroop Sarkar：我已经更改了默认端口，但仍然给出了相同的错误。谢谢
