websphere7 启动程序时报错FileUploadException

Question

我也查了一些解决办法，都不好使。比如设置类加载顺序，或者将mar包复制成jar包放在lib下。感觉没有什么规律，我有两个war包，是一个程序的不同版本a，b。a是原始版本，一直没有问题。b是新版本的，报如下错。可是这几天我又重新部署a，启动程序的时候也报下面的错，就好像原来好使的程序，突然就不好使了。另外，war包在tomcat下运行没有问题。WarBasedAxisC E org.apache.axis2.deployment.WarBasedAxisConfigurator <init> org.apache.commons.fileupload.FileUploadException

是少包了吧！

Answer 2

看下有commons-fileupload.jar这个包么？

Answer 3

包是肯定不会少的，而且在tomcat下运行正常

参考了一些解决办法，调整类加载顺序不报原来的错，但是报了一堆别的错，而且也不太想改类的加载顺序，这样改动太大，部署的时候增加了复杂性

Answer 5

包可能是在，但这个错误也确实是存在着的，不会无缘无故
Caused by: java.lang.ClassNotFoundException: org.apache.commons.fileupload.FileUploadException由于某些原因，即使jar包存在也导致找不到类，这需要你多试验

Answer 6

was的classloader是类似JVM的树级加载的，也就是说父classLoader加载了的类，子classLoader不会再加载检查你的两个war应用，是否每个war是单独的classloader？在多应用部署环境下应尽量设置WAS的classLoader类为每个war独立一个

Answer 7

websphere 控制台去查看每个应用已经装载的jar文件 然后看看对应的commons-fileupload jar包是否应经正常装载了

Answer 8

你既然是移植过去的,就把buildpath重新构建一下,这个错误提示就是少包了才造成的!

-----------------------------
怎么看已经装载的jar文件

Answer 10

但是在tomcat下就没有问题，说明还是和was冲突了吧

Answer 11

会不会和was自带的jar包冲突导致找不到类？更改下类加载顺序试试

Answer 12

删除IBM\WebSphere\AppServer\plugins\org.apache.axis2.jar，然后重新启动WAS的服务可以解决，但是感觉不是很好
