我不知道如何，但 jboss 正在尝试从其他已部署的 war 文件加载依赖项，该文件以链接错误结束。所以我的 SOAP 网络服务失败了。
举个例子； 我已经部署了一个 war 文件 A.war 并到目前为止正在工作。然后，我编写另一个包含 Web 服务的 Web 应用程序并部署它。当我尝试调用我的第二个应用程序 (B.war) 时，它试图转到 A.war 来定义模块
请参阅下面的异常。这花了我 2 天的时间，现在我每时每刻都快疯了。
Jboss版本是:7.1.3

有趣的是，这是我启动 jboss 后第一次。如果我这次尝试重新运行相同的测试，则不会显示最后一个 ClassNotFoundException。
最佳答案
重新启动JBoss
说真的。我遇到了完全相同的问题。它只发生在我们的一个环境中。它不知从何而来。我决定在深入研究问题之前重新启动 JBoss 实例 - 问题已解决。
关于Jboss 尝试从其他 war 文件加载依赖类，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/24088387/
