我已经安装了 Websphere Network 部署服务器 7.0.0.0 我已经在上面配置了一个集群。我在上面配置了一个数据源,说 ORA_DS 这个数据源使用“JAAS - J2C 身份验证数据”当我通过单击“测试连接”按钮测试 ORA_DS 时,测试连接成功。
当我尝试使用我的 java 代码访问此数据源时,问题就出现了。
这是我访问数据源并创建连接的代码:
public class DSTester
{
/**
* Return the data source.
* @return the data source
*/
private DataSource getDataSource()
{
DataSource dataSource = null;
Hashtable<String, String> env = new Hashtable<String, String>();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
env.put(Context.PROVIDER_URL, "iiop://localhost:9811");
// Retrieve datasource name
String dataSourceName = "EPLA1";
if (dataSource == null)
{
try
{
Context initialContext = new InitialContext(env);
dataSource = (DataSource) initialContext.lookup(dataSourceName);
}
catch (NamingException e1)
{
e1.printStackTrace();
return null;
}
}
return dataSource;
}
public static void main(String[] args)
throws Exception
{
DSTester dsTester = new DSTester();
DataSource ds = dsTester.getDataSource();
System.out.println(ds);
System.out.println(ds.getConnection());
}
}
这是输出:
com.ibm.ws.rsadapter.jdbc.WSJdbcDataSource@17e40be6
Exception in thread "P=792041:O=0:CT" java.sql.SQLException: ORA-01017: invalid username/password; logon denied

如果我替换代码工作正常
ds.getConnection()
和
ds.getConnection("ora_user", "ora_password")
我的问题是我需要在不指定 Oracle 登录详细信息的情况下获得连接。
请在这个问题上帮助我。任何线索将不胜感激。谢谢
