smsclient.jar包冲突

 

Exception in thread "main" java.lang.LinkageError: JAXB 2.0 API is being loaded from the bootstrap classloader, but this RI (from jar:file:/C:/Genuitec/Workspaces/oa/WebRoot/WEB-INF/lib/smsclient.jar!/com/sun/xml/bind/v2/model/impl/ModelBuilder.class) needs 2.1 API. Use the endorsed directory mechanism to place jaxb-api.jar in the bootstrap classloader. (See http://java.sun.com/j2se/1.5.0/docs/guide/standards/)

解决办法：    

1、如果是application工程，则在程序中打印出

         system.out.println(System.getProperty("java.endorsed.dirs"));

          找到相应位置，将jaxb-api-2.1.jar和jaxb-impl-2.1.12.jar放到对应目录下即可。没有endorsed目录，自己建一个。

2、如果是java web项目，则在一个servlet之类的运行起来的项目中，打印：

         system.out.println(System.getProperty("java.endorsed.dirs"));

         找到相应位置，将jaxb-api-2.1.jar和jaxb-impl-2.1.12.jar放到对应目录下即可。没有endorsed目录，自己建一个。

         我的WEB项目中，打印出来的路径是：E:\Java\apache-tomcat-7.0.19\endorsed
