DOM4J使用schema验证XML文件

本文的jar包及版本dom4j-1.6.1.jar,jaxen-1.1-beta-6.jar,xercesImpl-2.6.2.jar

Schema文件org/soft/resource/shiporder.xsd.

我也试过,也不行!
我的程序在【 reader.setFeature("http://apache.org/xml/features/validation/schema", true);】处报异常,说没有通过验证!

我用你的方法试过了, 似乎不行啊, org.dom4j.DocumentException: null Nested exception: null at org.dom4j.io.SAXReader.read(SAXReader.java:484) at org.dom4j.io.SAXReader.read(SAXReader.java:343) at Dom4j.Dom4jTest.read(Dom4jTest.java:61) at Dom4j.Dom4jTest.main(Dom4jTest.java:26)

log上应该是XML文件找不到.我认为.
