我正在EclipseZone的Neil Bartlett的系列文章中研究OSGi入门。我在http://www.eclipsezone.com/eclipse/forums/t90796.html的第三节课上。
创建并安装jar文件后，启动它时出现问题：

这是清单：
Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Movies Lister
Bundle-SymbolicName: MoviesLister
Bundle-Version: 1.0.0
Bundle-Activator: osgitut.movies.impl.MovieListerActivator
Import-Package: org.osgi.framework,org.osgi.util.tracker,osgitut.movies
Export-Package: osgitut.movies;version="1.0.0",osgitut.movies.impl;version="1.0.0"
似乎缺少osgitut / movies / MovieLister类，但它在我创建的jar文件中。我怀疑清单中缺少某些东西，但我不知道是什么。
最佳答案
您得到一个NoClassDefFoundError，它指示MovieListener类本身不是完整的，并且依赖于超类或具有无法在捆绑包中解析该类的成员。
