我想连接到glassfish服务器，但每次运行预写入的程序时，都会出现此错误。我已经正确地安装了netbeans和glassfish 3，并且已经建立了服务器，所以我没有想法。错误在下面。非常感谢！

这可能是您的连接端口被占用的问题。尝试更改连接端口号并重新连接。找到个在目录\与GlassFish 3.0 \ GlassFish的\域\ DOMAIN1 \ config并更改端口号8080的任何其他像9999在下面一行domain.xml文件 -

<network-listener name="http-listener-1" port="8080" thread-pool="http-thread-pool" transport="tcp" protocol="http-listener-1"/> 

关闭该文件并重新启动了GlassFish服务器并重新运行您的程序。
