データベース接続に oracle と SQl 2005 の両方を使用する C# アプリケーションを使用しています。最近、SQL Server 2005 を Sql 2008 に移行しています。ドット ネット アプリケーションを使用してテーブルを SQL データベースにインポートしようとすると、次のエラーが発生します。

Java call terminated by uncaught Java exception: java.util.MissingResourceException: 
Can't find bundle for base name com.microsoft.sqlserver.jdbc.SQLServerResource, locale en_US

ORA-29532: Java call terminated by uncaught Java exception: java.util.MissingResourceException: 
Can't find bundle for base name com.microsoft.sqlserver.jdbc.SQLServerResource, locale en_US
ORA-06512: at "INTPL.DATASYNC_UTIL", line 8

[LAST_SAVED_ERR]

アップグレード中に、次のパス ReportDBMetaDataUtil.java も確認しました。

String password) throws ClassNotFoundException, SQLException
    {
        Connection conn = null;
        switch (dbType)     //M.C
        {
            case DB_ORACLE:
                conn =getRemoteOracleDbConnection (dbURL, user, password);
                break;
            case DB_SQL_SERVER:
                Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");      //sql server 2005
                //Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");    
//sql server 2000

                conn =DriverManager.getConnection(dbURL, user, password);
                break;
        }   

        return conn;
}

この問題を解決するための提案や参照のアイデアを教えてください。

慣用的な JDBC を書くことから始めます。これは、まさに投稿した種類のものを書くことから解放されるはずのインターフェースベースの API です。

Oracle か SQL Server かをチェックするコードを見た瞬間に、自分のやり方が間違っていることがわかります。

次に例を示します。
