无法强制Eclipse使用Saxon XSLT处理器

Question

我是OSGi的新手，正在使用Eclipse处理某些Java应用程序，并且需要使用XSLT处理器。我需要使用Saxon处理器。我在OSGi捆绑包类路径和MANIFEST.MF中包含了它的依赖关系，如下所示：

但是我遇到以下错误：

有人可以在这里帮助我吗？

关于， 阿密特。

Answer 1

您可能将变压器工厂初始化为：

TransformerFactory fact = TransformerFactory.newInstance();

使用与OSGi不兼容的服务加载机制。

尝试使用：

TransformerFactory fact = new net.sf.saxon.TransformerFactoryImpl();
