我正在尝试将我的应用程序与 jboss 类加载器隔离开来。
我已经在 jboss-classloading.xml 和 jboss-web.xml 中完成了设置，并放入了我的 WEBINF 文件夹。
它解决了这个问题，但开始遇到另一个问题，我继续搜索并且可以将解决方案视为隔离应用程序。你能提供这个问题的解决方案吗..
我正在使用 Jboss 5.1 企业版。
您能否让我知道以下问题正在创建什么。
我尝试了以下选项。
- 覆盖应用程序 lib 文件夹中的 xerces jar 并收到此错误
部署异常。

您能否让我知道如何识别应用程序正在加载哪个 jar（我尝试运行 classpath.sh）以及哪个 jar 正在创建冲突以及调试此问题的最佳方法是什么。
