无法在java 7 update 25中启动java web start

我尝试将JavaWebStart应用程序部署为

但当我启动我的应用程序时，我得到了一个例外：

我想我的问题是我的jar文件是自签名的。 请告诉我如何用证书签署jar文件

提前谢谢

自签名不是问题，但不同的签名可能不理解，请解释您的想法？“未能在java 7 update 25中启动java web start”DYM它在1.7.0_24（或任何其他版本的java）中工作？作为一般提示：确保使用检查JNLP。@AndrewThompson：当我在java 7 update 17或java 6中运行时，我的应用程序正常…&JaNeLA检查的结果是什么？
