Dom4J IllegalAccessError - JBoss 7部署错误

时间：2016-01-05 12:49:25

标签： java maven jboss seam

我将遗留应用程序迁移到Maven（希望以后远离Seam）。已经有很多故障和故障，AFAIK Seam在它可以使用的依赖版本上真的很变幻无常。

这个最新的错误我无法弄清楚。所以我有一个EAR与我的（EJB）Jar，一个War和Seam.jar，以及lib /文件夹。现在我实际上将Dom4J作为scope = provided的依赖项，因为JBoss AS 7.1提供了1.6.1版本。它被包含在lib /无论如何，我还没弄清楚为什么。

但是当从lib /.

中删除所有多余的罐子时，我得到了同样的错误

重申一下，当使用Ant构建文件构建时，此应用程序之前正在运行。 Maven生产的EAR虽然不会部署。我听说过类似的错误（但不完全相同），类路径中的依赖项加倍。我已经检查过（从lib /中删除后），除了JBoss中的那个之外应该没有。模块。

更新： POM结构： Super-POM是所有模块的父级，具有DependencyManagement并且还包含模块（现在）。 模块：Core-ejb具有代码和大量的依赖关系，主要是因为它们在JBoss /模块中提供。 Core-web生成WAR，对Core-EJB有dep。 Project-Web包括Core-Web，Project-EJB依赖于Core-EJB并使用shade-plugin将它们合并在一起（！）。 Core-EAR从shaded-project-ejb和project-web生成ear。 （结构很疯狂，但由传统应用决定）。

答案 0 :(得分：0)

看起来它与类路径上的多个版本存在冲突。

有一个公司特定的模块，只是将一堆罐子集成到一个模块中。确定之后，只有一个jdom - * .jar在路上，它起作用了。
