Netbeans沒有找到合適的數據庫

它似乎我無法連接到數據庫，我不確定如此爲什麼。數據庫連接屬性（ID，密碼，網址）是正確的，但我不確定如何解決問題。我收到以下錯誤。Netbeans沒有找到合適的數據庫

它不是關於屬性......它關於「jar」文件..要麼它不是在ClassPath ..或它完全丟失.. !! – 2012-03-06 16:27:45

ive添加文件到lib但我仍然得到錯誤 – 2012-03-06 16:33:12

你有任何其他在你使用的文件夾中的lib .. ?? ..我確信它的「lib不存在於類路徑」..！！ – 2012-03-06 16:35:18

嘗試通過在獲取數據庫連接的語句之前調用Class.forName（）來手動加載驅動程序類。例如，如果您正在使用MySQL數據庫，請在語句上方添加以下語句以獲取數據庫連接。

Class.forName("com.mysql.jdbc.Driver");

嘗試使用以下步驟將數據庫驅動程序（JAR（s））添加到類路徑中。這應該可以解決您的問題。

1. Select your project from the Projects explorer. 
2. Right click -> Properties. 
3. Select Libraries from Categories list. 
4. Click on Add JAR/Folder button. 
5. Add your jar(s) & click on OK to finish the process.
