我的 EJB 应用程序没有部署在 WebSphere 上？
My EJB application is not deploying on WebSphere?
我已尝试将应用程序安装到服务器上，当服务器尝试启动该应用程序时，我在日志中看到错误。堆栈跟踪中最相关的部分似乎是

我有一个 enterpraise 应用程序，这个 EJB jar 已添加到我的耳中。我没有任何编译错误，并且通过 maven.I 构建也成功，确实已将 log4j jar 文件添加为该项目的依赖项。
你能帮我看看我错过了什么吗？
只有两种方法可以从您部署的应用程序中找到依赖的 jar。
1 将其正确包含在 EJB jar 本身中。您应该检查打包的 EJB jar 文件的内容，以确认实际上包含了 log4j jar。使用 jar tf jar-file 或 winzip。
2 通过将 log4j JAR 文件添加为 Websphere 服务器实例上的共享库。在这种情况下，它将可用于部署在服务器实例上的所有应用程序。
如果您使用的是 Maven，请确保您没有设置 log4j 依赖项以使用
<scope>provided</scope>
选项。此选项不会在打包的应用程序中包含 log4j jar。
