java认证辅导:JBOSS远程调用
发布时间：2010/6/29 11:35:01 来源：城市学习网 编辑：ziteng
部署环境：
1.linux（RHEL5.0），JBOSS 4.2.2，JDK 1.5.0，部署JMS服务端（Vmware虚拟机）
2.win7 JMS客户端
通过JMS客户端调用JMS服务端，产生入下错误：

查不出原因，将客户端部署至linux中，可以正常调用JMS。又起了一个linux虚拟机，将客户端部署在上面测试，抛出异常为unknowhost，修改客户端主机/ect/hosts文件，增加服务端IP地址和主机名映射，service xinetd restart重启生效后，调用成功。
在网上搜罗后最终解决办法为修改JBOSS启动命令：
./run.sh -Djava.rmi.server.hostname=192.168.174.129 --host 0.0.0.0 > nohup.out &
（指定IP为hostname，避免出现UNKNOWHOST问题）
