weblogic和axis的冲突

WebLogic 8.1 ships with webservices.jar that conflicts with Axis' saaj.jar and prevents Axis 1.2 from working right out of the box. This conflict exists because WebLogic uses an older definition of javax.xml.soap.* package from Java Web Services Developer Pack Version 1.0, whereas Axis uses a newer revision from J2EE 1.4.
However, there are two alternative configuration changes that enable Axis based web services to run on Weblogic 8.1.
In a webapp containing Axis, set <prefer-web-inf-classes> element in WEB-INF/weblogic.xml to true. An example of weblogic.xml is shown below:
<weblogic-web-app>
  <container-descriptor>
    <prefer-web-inf-classes>true</prefer-web-inf-classes>
  </container-descriptor>
</weblogic-web-app>If set to true, the <prefer-web-inf-classes> element will force WebLogic's classloader to load classes located in the WEB-INF directory of a web application in preference to application or system classes. This is a recommended approach since it only impacts a single web module.
In a script used to start WebLogic server, modify CLASSPATH property by placing Axis's saaj.jar library in front of WebLogic's webservices.jar.

最近做项目就遇到这个问题了，本来AXIS挺好用的，可是搭配上WEBLOGIC真是，现实的错误就是NULL EXCEPTION。解决办法，网上GOOGLE“WEBLOGIC和AXIS得冲突”，不抄袭了。我是用set CLASSPATH解决的。除此以外 JDK1.4和JDK1.5关于XML的解析又是一个天上地下，之前做的项目是JBOSS搭的WEBSERVICES服务，发布平台的JDK1.4 客户端用的JDK1.5，由于XML得解析差别，JDK1.4是SUN做的XML解析方式，JDK1.5用的是apache的XML解析方式，客户端就是解析不了我这的东西，郁闷。后来和客户协商更改JDK版本，没有给公司报告，挨批了，不过幸好没什么状况。
