Question

我是硒的新手。我正在运行现有的selenium RC代码。当我尝试启动集线器时，我收到以下错误

无法找到tools.jar。预计在C：\ Program Files \ Java \ jre6 \ lib \ tools.jar中找到它 Buildfile：build.xml不存在！构建失败

所以我下载了JDK文件。然后我改变了系统变量现在它指向

C:\>echo %JAVA_HOME%
C:\Program Files\Java\jdk1.7.0_11

C:\>echo %PATH%
c:\ruby\bin;C:\ant\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C
:\Program Files\Windows Imaging\;C:\Program Files\Common Files\Roxio Shared\DLLS
hared\;C:\Program Files\Java\jre1.6.0_05\bin;C:\Program Files\Java\jdk1.7.0_11

C:\>echo %ANT_HOME%
C:\ant\bin\ant.bat

我运行了以下bat文件来启动集线器 - 启动hub.bat

title Hub
cd C:\selenium\Grid\selenium-grid-1.0.4
c:\ant\bin\ant launch-hub

输出

C:\selenium\Grid\selenium-grid-1.0.4>c:\ant\bin\ant launch-hub
Buildfile: build.xml

launch-hub:

我的培训文件说我应该 •等待查看“已启动套接字连接器”语句和“44”;

但我没有得到它。我认为这是因为SocketConnector失败了。请帮我解决。

Answer 1

这些行告诉您端口4444已被另一个进程打开

 [java] 2013-01-16 14:45:25.364::WARN:  failed SocketConnector @ 0.0.0.0:4444
 [java] java.net.BindException: Address already in use: JVM_Bind

您应检查此进程可能是什么并将其关闭，或修改build.xml以更改集线器启动的端口

在Windows上使用netstat -an

注意：如果您多次运行ant文件，打开4444端口的进程可能与您尝试启动的进程相同，但尚未终止。

Selenium RC - 网格集线器没有收听
