在Myeclipse里创建oracle连接时，出现:The Network Adapter could not establish the connection 错误

我们创建oracle连接时（oracle10g），url往往写成：jdbc:oracle:thin:@地址:1521:ORCL，如：jdbc:oracle:thin:@localhost:1521:ORCL。
此时，有可能会报出：Oracle 网络适配器不能建立连接问题——The Network Adapter could not establish the connection 。
原因是：@后面的地址的值不一定是localhost，或是127.0.0.1 。他真正的值是和Oracle 的安装目录下的product\10.2.0\db_1\NETWORK\ADMIN目录下的listener.ora和tnsnames.ora里的host后面对应的值一样的。
如，我机子上url为：
jdbc:oracle:thin:@192.168.0.8:1521:orclsid
这样就对了
