java - SAXBuilder jdom 给出异常

Question

这是代码:

Representation representation = representItem(exp.getItem(),MediaType.TEXT_XML);

            Document doc = new SAXBuilder().build(representation.getStream());
            XPath xpath = XPath.newInstance("/xnat:MRSession/xnat:scan/xnat:file");

当实例化 SAXBuilder 时，这会给我一个 InitationTargetException 错误。

有人以前有过这个吗？看起来这应该可行。

我要冒险地说出这句话 SAXBuilder可能在您的构建路径中，但不在您的运行路径中。
