远程连接ejb离奇出错，等解答中。。。。。。

[vincent_zh]

我正在做一个项目,使用jboss4.2 + ejb
现在测试中，出现了这样的一种错误

jboss服务器运行在windows机器上，jboss启动是已经加上 -b 0.0.0.0 参数

jdk我已经装了1.5的版本，在源里安装的
我还在/etc/profile里设置好了环境变量,在该文件的最后加如下语句，如下:
export JAVA_HOME=/usr/lib/jvm/java-1.5.0-sun
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

当用windows的客户端远程调用ejb时，可以正常运行，项目里其它人现在就是在windows进行开发
而我，同样的客户端代码，在ubuntu8.10下运行，出现异常，说是连接被拒绝，异常如下：

同样的代码，为什么在windows下能够正常的远程调用，而在ubuntu下却拒绝连接呢？？

等回答中。。。。。。。。。

Connection refused to host: server;

你的HOST地址到底是什么？难道真的是server这个字符串所代表的吗？
