IDE无法识别Tomcat启动

我正在使用Netbeans 11部署WAR文件。使用RUN时，IDE启动Tomcat，显示启动消息：

INFO - Starting ProtocolHandler [http-nio-8080]
INFO - Starting ProtocolHandler [ajp-nio-8009]
INFO - Server startup in 815 ms

但是，IDE的“运行”选项卡显示在超时后启动失败：

Deploying on TomEE
    profile mode: false
    debug mode: false
    force redeploy: true
Starting Tomcat process...
Waiting for Tomcat...
Starting of Tomcat failed.

不知何故，IDE没有正确地检测到Tomcat，因为Tomcat确实在8080端口上运行和侦听。我已经试过了，尤其是使用IDE代理和连接器的那个，但都不起作用

---

根据评论：

1） 我正在运行TomEE，尽管我认为在我的问题上与Netbeans的观点（甚至与TomEE本身）没有区别。老实说，我认为这是一个Netbeans-Tomcat通信问题，TomEE只是添加了一些库和其他东西，这些东西会影响以后的工作

2） 我使用的是自定义的

server.xml

，但现在我使用的是原来的：

我认为问题来自一台有两个网络接口的计算机。不知何故，Netbeans（很有可能，除非Tomcat有事做）错误地管理了这种情况，并且它无法检测到Tomcat启动了

我真的不知道如何解决它，但我断开了第二个接口，它似乎可以工作。这是非常烦人和不方便的，但它是一个有效的解决办法

我发现这是因为

sudo

非常慢，我发现有一个问题，sudo在有两个或更多网络接口的机器上速度非常慢。。。不相关，但解决方法是：（

echo“Set probe_interfaces false”| sudo tee-a/etc/sudo.conf

）

我也遇到了同样的问题，通过使用旧版本的tomcat解决了这个问题

我在使用Netbeans 11.1和11.3时遇到了这个问题

我在tomcat 8.5.54和9.0.34中收到了这个错误。

---

Tomcat在使用8.5.49版时工作正常，我在谷歌上搜索了一下StackOverflow，直到我在这里看到这篇文章才解决：

我下载了NetBeans11.1的源代码并用命令构建了它

ant -Dcluster.config=full

大约需要17分钟。在那之后，我和你一起跑步

ant tryme

然后我在工具->服务器中设置tomcat设置并打开我的项目。然后我试着运行它。太棒了，现在很好用

显然，这是NetBeans的一个bug。在NetBeans端解决这一问题并不难。

[1]如果您要部署到TomEE而不是Tomcat（根据“运行”代码段，您看起来是这样的），您能更新您的问题以澄清这一点吗？[2] 可以发布server.xml吗？[3] 在出现“Tomcat失败”消息时，Tomcat日志中是否有任何相关消息？[4] 除了被记录的错误消息（“启动Tomcat失败”）之外，还有什么问题吗？例如，如果您试图从NetBeans停止服务器，Tomcat的停止菜单项是否已禁用，即使Tomcat正在运行？[5] 这种情况是一直发生还是间歇性发生？好的。[1] 是否有任何相关内容被写入NetBeans日志（视图>IDE日志）？[2] 这对您一点帮助都没有，但仅供参考，其他一些人报告了NetBeans 11.2上Wildlfly的类似问题：。[3] 虽然我无法重现这两个问题，但这可能是NetBeans 11.x的问题？〔4〕由于这是一个可重复的错误，可能会考虑。谢谢。日志表明

ExecutionChecker.executionResult

失败（请参阅问题中的更新）。从我们所知道的情况来看没什么。我将再次重新安装Netbeans，就像我对Tomcat所做的那样，可能使用不同的版本。对-堆栈跟踪并没有真正添加任何新内容。似乎有一些关于Wildlfy和NetBeans不能正常通信的老NetBeans bug报告，尽管我没有看到Wildlfy 15的任何信息。我不确定重新安装NetBeans是否会有什么效果，但升级到NetBeans 11.2和/或Wildfly 18可能会有效果。在您现有的环境中尝试的另一件相当简单的事情（如果可行的话）是使用不同的服务器，这对我来说是完美的！经过大量的测试，我想我会有所进展。问题似乎与网络接口有关——我的计算机有两个接口，一个用于互联网，一个用于内部网络（需要在测试后部署战争）。如果我禁用了内部的一个，那么Tomcat显然被检测到了。有些事情没有得到正确的管理。（为了记录在案，我还尝试了Netbeans 11.2和10.0，但没有成功）谢谢，谢谢，谢谢！就我而言，这就是问题所在！我发现在NetBeans11.1 bin包中只替换一个jar文件就可以解决这个问题。这是enterprise/modules下的org-netbeans-modules-tomcat5.jar。
