带有已部署的动态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，我得到了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！

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

Answer 1

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。

Answer 2

我认为你的类路径是错误的。

在WEB-INF / classes下 ，检查这些文件夹>> org / openfaces / demo / services ，然后检查上一个目录Services中的类MenuItem 。

问候，
