Glassfish冻结在：
Information: JMXStartupService has started JMXConnector on JMXService URL service:jmx:rmi://192.168.0.119:8686/jndi/rmi://192.168.0.119:8686/jmxrmi
我尝试重新安装netbeans，重新安装glashfish，其他项目也无法正常工作。
我有时会收到一条错误消息：
Please check server admin user name and password properties.
Also please check the server log file for other possible causes.
我认为没有创建新的server.log文件，但该文件包含：
Caused by: javax.naming.ServiceUnavailableException [Root exception is java.rmi.ConnectException: Connection refused to host: 192.168.0.117; nested exception is:
Caused by: java.rmi.ConnectException: Connection refused to host: 192.168.0.117; nested exception is:

请帮我找一个解决方案。
