JBoss隔离ear部署问题- Ear模块彼此隔离

Question

我们有一个应用程序，我们将其打包为ear文件。我们在应用程序中使用seam。我们使用的是JBoss 5.1.0.GA。我们发现jboss管理控制台存在类冲突问题，因为它使用了seam。因此，我们决定在文件.../jboss-as/server/default/deployers/ear-deployer-jboss-beans.xml中将EARClassLoaderDeployer bean的isolated属性设置为true，从而将ear部署设置为isolated。

当我们这样做时，我们开始在我们的应用程序中获得ClassNotFoundExceptions，这是意想不到的。我认为设置独立的ear部署意味着ear中的模块仍然可以共享类？

找不到的类是ejb的接口。

有人对这个问题有什么建议吗？

connect-web-1.0.0-SNAPSHOT.war中seam库中的一个seam过滤器类正在尝试引用connect-domain-1.0.0-SNAPSHOT.jar中的一个EJB接口类。

Answer 1

通过创建war和ear共享的类加载器存储库修复了此问题。并更改了我的耳朵，以包括以前由JBoss提供的JSF库。
