我使用json—lib一系列jar包处理json和java对象之间的互相转换，同样的jar包在我写的测试程序里一切正常；可是当我将同样的代码和jar包导入正式项目后，就一直报错：

==========================================================================================
共同引用的jar包有：
commons-beanutils-1.7.0.jar
commons-collections-3.1.jar
commons-lang-2.1.jar
commons-logging-1.1.1.jar
ezmorph-1.0.6.jar
json-lib-2.4-jdk15.jar

测试程序里面除了以上这些jar文件之外就是struts的一些jar文件！
正式项目跟以上jar文件类似的有：
commons-beanutils.jar
commons-collections.jar
commons-lang.jar

一直以为是jar包冲突，但我将commons-beanutils.jar、commons-collections.jar、commons-lang.jar
删去也报同样的错误或者就是找不见net.sf.json.JsonConfig的错误

注：我项目用的是jdk1.6 Myeclipse 6.5 tomcat6.0

找了俩天都没有找到问题到底在哪？同样的文件和代码，在不同项目怎么就不行呢！求大侠指点啊！
