OSGi上的java.lang.NoClassDefFoundError [英] java.lang.NoClassDefFoundError on OSGi

问题描述

我有一个包，一个激活器声明。这个激活器创建一个JFrame并显示它。

在Eclipse上运行作为插件项目它可以正常运行。当我戴上Felix它不再工作了。
它显示：
java.lang.NoClassDefFoundError：com / griep / ui / MainFrame

但是MainFrame位于同一个包中当然，激活器是一个公共类。我不明白为什么类加载器没有找到类。

任何人都知道什么是发生？

解决方案

确保将 javax.swing 包导入你的包：

  Import-Package：javax.swing 
  

I have a bundle, with an activator declared. This activator create a JFrame and show it.

Running on Eclipse as Plugin project it works fine. When I put on Felix it doesn't work anymore. It shows: java.lang.NoClassDefFoundError: com/griep/ui/MainFrame

But MainFrame is located in the same bundle the activator is, as a public class, of course. I don't understand why the classloader isn't finding the class.

Anyone knows what is happening?

解决方案

Make sure you import the javax.swing package into your bundle:

Import-Package: javax.swing
