Netbeans 11无法管理Tomcat 9(已解决)

Question

早上好，我正在尝试在macOS中使用带有NetBeans 11.1和JDK11的Apache Tomcat9，但它不起作用。

我已经安装了Apache Tomcat9.0.31并在NetBeans中配置了Tomcat服务器，但是当我尝试启动服务器时，日志看起来没问题：

如果我在web浏览器中转到http://localhost:8080，我可以看到Tomcat服务器正在运行。问题是Netbeans说：“启动apache Tomcat...”几分钟后，来自NetBeans的一个错误出现：“启动Tomcat失败”，我无法从netbeans部署任何web应用程序，但在web浏览器中，我可以看到它正在运行。

我尝试配置环境变量，如JRE_HOME、JAVA_HOME、CATALINA_HOME、CATALINA_BASE。另外，在Netbeans常规代理设置中选中“无代理”，并在server.xml中配置连接器，如下所示：

<Connector
      connectionTimeout="20000"
      port="8080"
      protocol="HTTP/1.1"
      redirectPort="8443"
      server="Apache-Coyote/1.1"
    />

但它不起作用。

我不知道我能做些什么来解决这个问题。

提前谢谢。

我已经解决了这个问题：https://issues.apache.org/jira/browse/NETBEANS-3903

Answer 1

我不是mac用户，而是Ubuntu用户。我也面临着这样的问题。我所做的是从终端停止tomcat，然后尝试从Netbeans运行我的应用程序或从Netbeans启动tomcat (Services选项卡)。

此外，如果您没有使用manager-gui,manager-script定义tomcat用户，则不能使用netbeans中的tomcat (我不确定管理员角色)。

<role rolename="admin"/>
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<user password="YOUR_PASSWORD" roles="admin,manager-gui,manager-script" username="YOUR_USERNAME" />

Answer 2

我在Netbeans 12上也遇到了类似的问题，我通过将JDK版本更改为最新版本来修复它。
