如何使用我自己的WAR文件覆盖JBoss模块？

标签： jboss override classloader jboss7.x war

我正在使用JBoss 7.1.1并尝试使用Apache Commons Lang 3.3部署WAR文件。 JAR位于我的WAR文件中的WEB-INF / lib文件夹中。但是，当我运行我的Web应用程序时，我得到以下错误/异常，我认为这是因为JBoss正在使用它自己的旧的commons-lang库。如何在不修改JBoss安装的情况下覆盖JBoss commons lang模块？

对我而言，您的代码（或至少org.mainco.subco.dido.service.TrainingSessionServiceImpl中的代码）仍然使用较旧版本的commons-lang。如果您查看Javadoc for commons-lang 3，则会看到代码位于org.apache.commons.lang3而不是org.apache.commons.lang3。
