数据库连接错误

Pl/SQL  

连接数据库  看ip地址

在PL/SQL中选择Help-->Support Info... ->查看DNS File C:\oracle\ora90\network\Admin\tnsnames.ora   ->查看jdbcurl.java连接数据库IP-->查看数据库登录名和密码

#dev slisoper/slisoper

newdev2 = (DESCRIPTION =

    (ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.8.200.105 )(PORT = 1521))

    )

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SID = lifedev)

    )
  )

根据jdbc连接数据库的ip地址

public JdbcUrl()

 {

 DBType = "ORACLE";

        IP = "xx.x.xxx.xxx";

        Port = "1521";

        DBName = "lifedev";

        UserName = "sss";

        PassWord = "sss";

}

public String getJdbcUrl()

    {

        String sUrl = "";

        if (DBType.trim().toUpperCase().equals("ORACLE"))

        {

            sUrl = "jdbc:oracle:thin:@" + IP + ":"

                    + Port + ":"

                    + DBName ;

        }

        if (DBType.trim().toUpperCase().equals("INFORMIX"))

        {

            sUrl = "jdbc:informix-sqli://" + IP + ":"

                    + Port + "/"

                    + DBName + ":"

                    + "informixserver=" + ServerName + ";"

                    + "user=" + UserName + ";"

                    + "password=" + PassWord + ";";

        }

        if (DBType.trim().toUpperCase().equals("SQLSERVER"))

        {

            sUrl = "jdbc:microsoft:sqlserver://" + IP + ":"

                    + Port +

                                        ";databaseName=" + DBName + ";selectMethod=cursor";

        }

                if (DBType.trim().toUpperCase().equals("WEBLOGICPOOL"))

                {

                  sUrl = "jdbc:weblogic:pool:" + DBName ;

                }

        return sUrl;
