Java 绑定Osgi无效

我开始新的osgi。。我的项目正在运行java应用程序，但没有运行osgi。 问题是：

org.osgi.framework.BundleException: The activator osgi.Activator for
bundle osgi is invalid at
org.eclipse.osgi.framework.internal.core.AbstractBundle.loadBundleActivator(AbstractBundle.java:172) at

看起来您的

osgi.Activator

类注册为Activator，但未实现

org.osgi.framework.BundleActivator

code..code..code！！！啊！Java堆栈跟踪在我的整个屏幕上。现在连看都看不见。谁来换一页！（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blockquote来显示堆栈跟踪。@ItayGrudev最好有完整的堆栈跟踪IMHO，但要用代码块格式化。@Puce注意并编辑。。）我解决了这个问题，但现在遇到的不同问题是：org.osgi.framework.BundleException:bundle deneme.Activator.start（）中的异常。原因：java.lang.NoClassDefFoundError:com/sun/codemodel/JCodeModel@alperenbolat如果这是一个不同的问题，考虑开始一个新的问题。否则，请用所有必要的信息（代码、错误消息、堆栈跟踪等）更新您的问题，谢谢我解决了所有问题。。我的代码正在运行
