java – 部署了动态Web项目的WebSphere ClassNotFoundException

问题

我目前正在使用WebSphere 7.0应用程序服务器上部署的EAR(使用OpenFaces Web项目)遇到ClassNotFoundException. EAR部署没有任何问题,但是当我从Web项目(包含在EAR中)访问页面时,我得到ClassNotFoundException(下面).我已导出EAR以确保一切都在那里并且包含WAR文件.当我查看WAR文件时,未找到的类包含在WEB-INF / classes文件夹中.例外是指Web项目中的类,如果有帮助,则不在JAR中.我猜我在项目配置中遗漏了一些东西.任何和所有的反馈非常感谢！

错误

Web项目配置

>构建Web项目src的路径：OlympusAetherUI / WebContent / WEB-INF / classes
>为src：WEB-INF / classes部署路径

EAR部署程序集

>来源：OlympusAetherUI部署路径：OlympusAetherUI.war
>来源：OlympusCommon部署路径：lib / OlympusCommon.jar
>来源：OlympusGenerated Deploy路径：lib / OlympusGenerated.jar

解决方法:

找到问题的根源. commons-digester.jar需要位于WEB-INF / lib中,以便能够找到MenuItem类,因为EAR类路径不具有对Web类路径的可见性.
