從netbeans運行應用程序並運行jar之間有什麼區別？

我有一個java應用程序，從Netbeans 7.1運行時完美工作，但如果我使用構建jar崩潰。從netbeans運行應用程序並運行jar之間有什麼區別？

我一直在調查這個問題，我注意到該應用程序在調用DriverManager.getConnection（）時保留。

我做這樣的事情：

Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); 
Connection con = DriverManager.getConnection("jdbc:sqlserver://127.0.0.1:2304;user=username;password=12345;database=databasename");

我也試過JTDS但它有同樣的結果。

我上運行Windows 7家庭高級版的SQL Server 2008（本地主機） Java版本1.6

線程轉儲的Netbeans 7.1（從NetBeans中運行時，應用程序正常工作）

什麼可能造成這種情況？

定義「崩潰」。 Stacktrace會有所幫助。 –

我沒有堆棧跟蹤，因爲應用程序在調用getConnection之後才持有堆棧跟蹤。沒有發生異常，GUI停止響應。 – woozy

@woozy你可以採取線程轉儲，看看發生了什麼？ – r0ast3d

也許您在運行jar文件時未將CLASSPATH設置爲包含SQL Server驅動程序，而Netbeans可能已將它包括在內。

謝謝你的回覆。我有正確的類路徑。而且，如果這是問題，則會拋出異常，情況並非如此。該應用程序只是成立。 – woozy

我的DriverManager.getConnection調用只是無限期地掛起了同樣的問題。

什麼解決了我回到Java 6 Update 25的問題。更新29似乎引入了與SQL Server的JDBC連接的錯誤。我認爲Update 27（或更早版本）仍然可以正常工作。
