我是ogsi的新手，当我在knopfletfish框架中运行bundle时，我得到了这个错误：

我不知道为什么会发生这种情况，我已经引用了所有的jabxb jar，也许很重要的说它发生了，因为我用jdk7更改了jdk8以便与另一个jdk7包一起工作。

这是标记例外的类：

Answer 1

我认为您需要将com.sun软件包添加到引导委派中。

org.osgi.framework.bootdelegation=com.sun.*

Answer 2

使用Bean中的Wrapper类与getter和setter。不要在bean类中使用带有getter和setter的原始数据类型。

错误：int i;
右：Integer i;

使用knopfletfish的NoClassDefFoundError：com / sun / xml / internal / bind / DatatypeConverterImpl
