令人崩溃的一次调试org.xml.sax.SAXNotRecognizedException

<div class="iteye-blog-content-contain" style="font-size: 14px"></div>

最先是NullPointException，找到出错原因，JaxbUtil移动到core内，但是在web端没有引入相应的jaxb-api以及jaxb-impl，所以在web的Maven库中手动追加，空指针异常解决，然后令人崩溃的org.xml.sax.SAXNotRecognizedException出现了，异常信息：

     因为第一次使用JAXB，所以对其异常完全不懂，只能上网查，然后一个个试，所有办法都尝试过后，在最后濒临绝望的时候，看到了http://hi.baidu.com/ljmybfq/item/c2264b560cd52fc29f266739，抱着死马当活马医的心态进行了最后一次尝试，删掉了xercesImpl-2.6.2.jar，xml-apis-1.0.b2.jar，xmlParserAPIs-2.6.2.jar，没想到真的成功了！值得撒花庆祝！~~

 

    长知识了，感谢http://hi.baidu.com/ljmybfq/item/c2264b560cd52fc29f266739的分享者！~

同事写的程序，到我的机器运行。应用服务器用的是tomcat，开发环境是MyEclipse+Struts1.2+Hibernate3.1+Spring2.0。

部署好系统，启动服务器时出现异常如下：

org.xml.sax.SAXNotRecognizedException: http://apache.org/xml/features/validation/dynamic

半天来，找不出原因，上网查了半天，众说纷纭。

后来发现，由于使用了Hibernate，其中的包与struts中的包有重复。

在构建路径中删除以下包：

xml-apis.jar，xerces-2.6.2.jar，commons-logging-1.0.4.jar，commons-collections-2.1.1.jar，antlr-2.7.5H3.jar。

相应物理路径下的文件也要删除。

测试通过！
