Question

我正在尝试在Netbeans中启动Tomcat，不幸的是它停留在“org.apache.catalina.startup.Catalina.start服务器启动时间为793 ms”。过了一会儿，我收到一条错误消息弹出窗口，说启动Tomcat失败了。我正在使用Mac OS

这是我看到的所有输出：

有人可以帮帮我吗？

Answer 1

我通过修改server.xml并添加server="XXXXXXX"找到了此修复程序，其中XXXXXXX应与netbeans中的网络服务器名称相同。

例如，server="Apache Tomcat or TomEE"

Answer 2

检查您的网络浏览器，如果在启动tomcat后您可以访问localhost（如果您还没有更改端口号，则在http://localhost:8080/下）。

如果有效： - 应用程序 - 服务器通信存在问题（您是否正确部署了应用程序？是否存在可能阻止您的应用程序运行的防火墙？）

如果没有： Tomcat配置不正确。您可能会尝试在Netbeans外部启动它（例如在控制台中）以查看它是否有效。如果没有，请重新安装Tomcat。

Answer 3

尝试一下：
- 在Web浏览器地址栏中手动正确输入Web应用程序路径。
- 因为IDE不知道启动路径。或者您必须在<welcome-files-list>中设置web.xml元素。

Answer 4

我有同样的问题，但这解决了这个问题：

嗨，我只是想指出一个观察。我发现了   从netbeans开始到1.7.2（加）作为服务器，netbeans不是   太高兴关于8080上的server =“Apache TomEE”配置   连接器。所以通过删除这一个启动再次确定。

我猜netbeans tomee（和tomcat）扩展中的一个错误。

Answer 5

在我的Mac上发生在我身上。

原因是网络变化=＆gt;我在网络设置上设置静态IP。

Answer 6

没有其他答案对我有帮助，也没有任何记录，因此我走了很长一段路，在Java调试器中调试了NetBeans，以找出问题所在。这让我发现NetBeans被拒绝了与Tomcat Manager Web应用程序的TCP套接字连接，这使它错误地认为Tomcat不存在。

解决方案：

添加

-J-Djava.net.preferIPv4Stack=true

到netbeans.conf文件中的命令行选项（键“ netbeans_default_options”）。

如果这仍然对您没有帮助，您可以在org.netbeans.modules.tomcat5.util.Utils＃pingTomcat（）中设置一个断点，并跟踪在那里发生的事情。

无法启动Tomcat
