Question

我刚刚开始将NetBeans用于我的项目，我需要在GUI中使用一个仪表。我遇到了看起来非常有前途的Steelseries，并下载了这个JAR文件：

http://www.java2s.com/Code/Jar/s/DownloadSteelSeries3926jar.htm

我创建了一个Java项目，将库添加到其中，并添加了Swing调色板。像Lightbulb，Led和TrafficLight这样的bean很好用;但是当我选择一个仪表时，我得到了这个错误：

＆＃34;无法加载组件类eu.hansolo.steelseries.extras.Radar JAR文件。班级本身被发现了，但是有一个问题初始化它，例如由于静态初始化程序中的异常，或无法加载组件类所需的其他类。＆＃34;

异常堆栈跟踪如下：

最初在SteelSeries托管的

Kenai已移至GitHub。该项目取决于Trident库，如here和pom.xml所示。

您是否也知道为什么Steelseries库缺少那些需要的模块？

您提到的link引用了预先构建的JAR文件，每个文件都排除了here所见的从属lib目录或引用的工件引用here。您采取的确切方法取决于您的software configuration management计划。

将Steelseries JAR文件加载到Swing调色板
