1·我看到的惟一可能出现问题的情况是，您当前正将端口8081用于其他地方(比如tomcat)。
The only possible problem I can see is if you are currently using port 8081 for something else (such as Tomcat).
2·它从来没有停止我的其他Apache实例，而且能够在端口8081上与Jaxer实例通信，也没有出现问题。
It never brought down my other Apache instance and was able to communicate with the Jaxer instance on port 8081 with no problems.
3·但是，如果您的网络阻塞端口8081和1533上的TCP通信，那么可以考虑启用这个选项。
If you are dealing with a network that blocks TCP communications on ports 8081 and 1533, though, you might consider enabling this option.
4·例如，在图3中有两个应用程序；应用程序1通过HTTP端口8081进行访问，应用程序2通过HTTP端口8082进行访问。
For example, in Figure 3, there are two applications; application 1 access is via HTTP port 8081 and application 2 access is through HTTP port 8082.
5·在Web App Debugger对话框中，可以单击Start按钮，使其“监听(listen)”指定的端口(例如8081)，如图9所示。
In the Web App Debugger dialog, you can click on the Start button to make it "listen" to the specified port (for example, 8081), as shown in Figure 9.
