Question

尝试使用JWS（JNLP）启动时运行Jar应用程序。它一直在给我这个错误。甚至找不到错误的地方。任何指示都会有所帮助。

如果有人可以告诉我这个错误的潜在位置在哪里，我可以在这里发现该代码。

注意：我安装了最新的Java 8并在Netbeans上工作。如果手动调用java -jar testTool.jar

，jar文件的效果很好

更新

Answer 1

如果有人有同样的错误，即使使用java 8 Update 101：

，也会在此处发布此信息

在我们的特定情况下，经过几个小时的挖掘，问题最终是NetBeans版本7.4在jar Codebase的{{1}}属性上放了一些无用的垃圾;通过进入项目属性MANIFEST.MF，然后将Application -> Web Start更改为Codebase和User defined更改为Codebase Preview，应用程序开始正常运行。

请注意我们使用小程序代替JNLP应用程序，因此您的里程可能会有所不同。

Answer 2

看起来像一个已知问题...请参阅Bug #236765

按照错误中的说明升级您的Java版本。

不是NB问题，javaws问题。我已经测试过了 https://netbeans.org/kb/73/java/javase-jws.html与JDK 1.7.0_45和工作正常。请更新JDK JRE。
