本文介绍了解决EJB远程调用Jboss服务器时出现的未知主机异常问题的方法。通过正确配置JBoss服务器的启动参数，可以避免此类异常并成功建立远程连接。

EJB调用远程连接Jboss服务器，参考代码：

Properties prop = new Properties();
prop.put("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
prop.put("java.naming.provider.url", serverIp+":"+port);// 1099
InitialContext ctx = new InitialContext(prop);
NamingEnumeration nn = ctx.list("");
while (nn.hasMore())
{
System.out.println(nn.nextElement().toString());
}

可能会出现如下错误。

原因在于JBosss服务器启动时，指定了-b 0.0.0.0

应该为：

run.bat -b 你本地服务器的Ip地址
