Jar文件找不到com.mysql.jdbc驅動程序

我想在java中連接到mysql數據庫的應用程序。爲此，我下載了mysql-connector-java-5.1.16-bin.jar連接器。Jar文件找不到com.mysql.jdbc驅動程序

我還在CLASSPATH環境變量中添加了上述jar文件的路徑。

我創建了應用程序並執行了java文件並正確執行。

然後，我創建的應用程序的jar文件，並試圖執行它，然後我得到了以下錯誤

例外：com.mysql.jdbc.Driver

我覺得jar文件無法找到com.mysql.jdbc.Driver

請幫忙!!!

如果你的JAR文件是通過使用-jar選項執行，或通過雙擊它，然後CLASSPATH環境變量還有-cp或-classpath選項將被忽略可執行的JAR文件。

對於可執行JAR文件，必須在JAR的清單文件中指定類路徑。

有關在清單文件中指定類路徑的更多詳細信息，請參閱Oracle的Java教程中的此頁：Working with Manifest Files。

通常，您不想使用CLASSPATH變量，而是使用-cp標誌指定庫位置。

java -cp /path/to/jar:/path/to/other/jar Main

但是如果我想創建一個可執行的jar文件。我想用雙擊打開它 – Jonah 2011-05-15 18:26:18

真的不同的問題，但可以找到一個很好的答案。這裏：http://stackoverflow.com/questions/2018257/how-to-combine-library-with-my-jar也在這裏http://www.ibm.com/developerworks/library/j-jar/index.html – zellio 2011-05-15 18:31:44

謝謝Mimisbrunnr IBM鏈接非常有幫助 – Jonah 2011-05-15 18:41:42
