在独立 Equinox 上加载 org.w3c.dom.Node 异常

Question

当我的应用程序在 Equinox 上以独立模式运行时，它会启动 NoClassDefFoundError 来查找 org.w3c.dom.Node 类。

这个类是框架提供的吗？在命令行上，我运行了命令 getprop 并且此类列在 org.osgi.framework.system.packages 属性中。

我已经检查了 MANIFEST 文件中的导入标记，一切正常。

有什么想法吗？我做错了什么？

这里是 MANIFEST：

Answer 1

您是否也将 org.w3c.dom 导入到 Manifest 中？

Answer 2

在命令行上，我运行了命令 getprop ，这个类是
在 org.osgi.framework.system.packages 属性中列出。

您已将类的包（例如org.w3c.dom）而不是类（org.w3c.dom.Node）添加到org.osgi .framework.system.packages 或 org.osgi.framework.system.packages.extra 属性。

---

另一个想法：在所有项目中搜索 org.w3c.dom.Node 用法，并检查使用此类的每个包是否在清单中导入其包。我猜您的 OperationSetPresenceSipImpl 使用了其他包中的类，该包也需要 org.w3c.dom.Node。也许第 3 方库也在其他包中使用 Node 类。

ClassNotFoundException 和 NoClassDefFoundError 之间有什么区别？
