第二次被CXF+Oracle Weblogic11g 折磨

Tomcat上调试好的程序发布到weblogic上，又碰到jar包问题.

问题现象1

Invocation of init method failed; nested exception is java.lang.LinkageError: 
  loader constraint violation: when resolving field "DATETIME" the class loader (instance of weblogic/utils/classloaders/ChangeAwareClassLoader) 
  of the referring class, javax/xml/datatype/DatatypeConstants, and the class loader (instance of <bootloader>) for the field's resolved type, 
  javax/xml/namespace/QName, have different Class objects for that type

分析：工程之前已经设置weblogic.xml优先用web/lib下面的包

<weblogic-web-app>
	<container-descriptor>
		<prefer-web-inf-classes>true</prefer-web-inf-classes>
		</container-descriptor>
  </weblogic-web-app> 

"javax/xml/namespace/QName"无法识别这个错误之前已经碰到过，因为 Apache CXF 里的类的时间晚于 Weblogic 里的类的时间，而且类的二进制内容也发生了改变，
  于是原来 Weblogic 里的其它类由于我们通过了 prefer-web-inf-classes 设置为 true 后，而引用到了现在的 Apache CXF 里的类了，就发生了 java.lang.LinkageError 错误。

解决方式是把工程下所有带javax/xml/namespace/QName class的都删除掉。

问题现象2.

解决Qname继续启动，出现这个错误。分析原因还是Jar包问题，从com.sun.xml.ws分析可以看出来启动的时候还是没有使用CXF的包路径.

总结问题1和问题2，我们的目的就是要使用自己的包路径，如果冲突的包不多，将jar包加载到weblogic setDomainEnv里面是最简单的.
  比如设置

set PRE_CLASSPATH=C:\temp\webroot\WEB-INF\lib\antlr-xxx.jar;

对于需要修正的类路径可以通过下面的方法进行设置，而不是只用" prefer-web-inf-classes=true" 这个锤子去敲所有的钉子。

<?xml version="1.0" encoding="UTF-8"?>
	<weblogic-web-app xmlns="http://xmlns.oracle.com/weblogic/weblogic-web-app">
  <container-descriptor>
    <prefer-web-inf-classes>false</prefer-web-inf-classes>
    <!--提示即使weblogic即使有这个包也要优先使用下面路径的内容-->
    <prefer-application-resources>
 		<resource-name>META-INF/services/javax.xml.ws.spi.Provider</resource-name>
    </prefer-application-resources>
    <prefer-application-packages>
      <package-name>org.python.core.*</package-name>
    </prefer-application-packages>
  	</container-descriptor>
	</weblogic-web-app> 

折腾几个小时，服务启动了，天下太平了。。

新问题

Caused by: java.lang.NoSuchMethodError: org.joda.time.DateTime.<init>(IIIII)V

显然也是jar包找不到了，将org.joda.time.*加入

    <prefer-application-packages>
      <package-name>org.python.core.*</package-name>
      <package-name>org.joda.time.*</package-name>
    </prefer-application-packages>

搞定！
