Java dom4j org/jaxen/NamespaceContext exception
提问by Mr.
I have downloaded dom4j-1.6.1and added it to java's build path. I am also familiar with java.lang.NoClassDefFoundError: org/saxpath/SAXPathExceptionbut I keep getting an exception.
我已经下载了dom4j-1.6.1并将其添加到 java 的构建路径中。我也熟悉java.lang.NoClassDefFoundError: org/saxpath/SAXPathException但我不断收到异常。
Enclosed a snippet:
附上一个片段：
public class Parser {
public static void parse(final String path) throws Exception {
final SAXReader reader = new SAXReader();
final Document document = reader.read(new File(path).toURI().toURL());
if (document == null) return;
List list = document.selectNodes("/");
for (Object o : list)
System.out.println(o);
}
}
When I run it, I get the following stack trace
当我运行它时，我得到以下堆栈跟踪

The Exception:
例外：
java.lang.ClassNotFoundException: org.jaxen.NamespaceContext
Maybe you forgot to include the jaxen.jarin your Java build's path.
也许您忘记jaxen.jar在 Java 构建的路径中包含 。
