我新启动 osgi.. 我的项目正在运行 java 应用程序但没有运行 osgi 。问题：

【问题讨论】：

代码..代码..代码！！！
啊！我的整个屏幕上的 Java 堆栈跟踪。现在也看不下去了。请有人换页！（说真的！你只需要前几行并添加一些代码！）
请使用代码块而不是块引用来显示堆栈跟踪。
@ItayGrudev 恕我直言，最好有完整的堆栈跟踪，但用代码块格式化。
@Puce 已注明并已编辑。 ;)

【解决方案1】：

org.osgi.framework.BundleException: The activator osgi.Activator for
bundle osgi is invalid at
[...]
Caused by: java.lang.ClassCastException: osgi.Activator cannot be cast
to org.osgi.framework.BundleActivator at

看起来您的osgi.Activator 类已注册为激活器，但未实现org.osgi.framework.BundleActivator

【讨论】：

我解决了这个问题，但现在我遇到了不同的问题：org.osgi.framework.BundleException: Exception in deneme.Activator.start() of bundle deneme。引起：java.lang.NoClassDefFoundError: com/sun/codemodel/JCodeModel
@alperenbolat 如果这是一个不同的问题，请考虑开始一个新问题。否则，请使用所有必要信息（代码、错误消息、堆栈跟踪...）更新您的问题
谢谢我解决了所有问题..我的代码正在运行
