Java可执行文件Jar文件

我想从eclipse制作一个可执行的jar文件（使用MySQL作为数据库）。Java可执行文件Jar文件

如何才能使可执行jar文件？

我做了一个，但它显示了一些警告，并没有奏效。我收到一个很长的警告列表。下面是警告：

什么是警告？ – 2012-04-23 11:53:50

**更改IDE使用的编译设置，以显示警告的*详细信息。** – 2012-04-23 12:22:21

要了解有关**运行时错误的更多信息，请启动该应用程序。从命令行使用类似'java -jar the.jar' – 2012-04-23 12:24:39

文件 - >导出 - >运行的JAR文件

然后你可以选择，天气要在罐子复制罐或只是extact他们

我试过这个，但是它被导出时有警告并且jar文件没有执行 – 2012-04-23 12:04:32

警告不会阻止你启动jar。试试$ java -jar filename.jar。什么发生？你究竟说什么“不起作用” – AvrDragon 2012-04-23 12:08:33

右键点击需要导出的项目为瓶子
从列表中选择选项'导出'
在新的弹出，选择“运行的JAR文件”
点击“下一步”按钮
在下一个窗口中给出你的JAR的名称和启动配置（与主方法的类）
选择所需的库相应的选项，然后单击完成按钮

尝试在导出之前修复警告。 – 2012-04-23 12:28:52

你有一个可执行的主类吗？你有主要功能吗？如果你从eclipse中运行'run'，它会运行吗？ – Woody 2012-04-23 13:05:30

“它显示了一定的警示作用，而不是作品” 请记住，我们将不能够帮助你多少，如果你不提供什么错误的详细信息你遇到：http://imgur.com/jacoj

Eclipse可能会警告您，您的可执行jar文件已经创建并带有警告。这只意味着你的班级有警告（黄色！）。它并不意味着生成的jar文件将不起作用。

警告仅仅是罚款，这将不会导致一个概率与可执行的JAR

检查<Your JAR name>.jar\META-INF\MANIFEST.MF并找到Main-Class: <your entry point class with main method>

如果这Main-Class是不是有比一些错误，同时创造罐子。

确保您遵循适当的步骤。请检查这个guide for creating jar作为参考。

注意：您可以手动编辑MANIFEST.MF

*“警告就好”*警告不应忽视。他们报道是有原因的。 – 2012-04-23 12:21:10

@Andrew我不知道这个警告如何导致问题，使罐作为可执行文件。你能解释一下吗？我非常清楚，这是有目的的。 – Avil 2012-04-23 12:25:46

这取决于警告是什么，仍然在等待来自OP的详细信息。 – 2012-04-23 12:26:42
