大家好：

我的网站在发布时遇到了一下的问题：

数据库连接：

jdbc.driverClassName=oracle.jdbc.driver.OracleDriver

jdbc.url=jdbc:oracle:thin:@dasdwwwww.exadata.eeaseee.se:1521/SEANPRD

jdbc.user=DBUSER

jdbc.pass=DBPASSWORD

@Bean(name="dataSource", destroyMethod="close")

public DataSource bamsDataSource() throws PropertyVetoException {

ComboPooledDataSource dataSource = new ComboPooledDataSource();

dataSource.setDriverClass(env.getProperty("jdbc.driverClassName"));

dataSource.setJdbcUrl(env.getProperty("jdbc.url"));

dataSource.setUser(env.getProperty("jdbc.user"));

dataSource.setPassword(env.getProperty("jdbc.pass"));

dataSource.setCheckoutTimeout(10000);

dataSource.setMinPoolSize(1);

dataSource.setMaxPoolSize(15);

dataSource.setMaxStatements(50);

dataSource.setMaxIdleTime(1200);

dataSource.setIdleConnectionTestPeriod(6000);

return dataSource;

}

具体细节是这样的：

我的网站需要远程访问另一个网站的数据库，应对方网站提供的连接信息，我可以通过电脑上的Client连接并且访问对方的数据库，我的网站在我本机的Eclipse上运行也可以访问对方的数据库。

但是当我发布我的网站到服务器上的时候，是连接不上的。从我的服务器，我可以ping通，telnet 和 traceroute到对方的网站。

请问我还有什么对方没有配置好？

非常感谢
