我有一个enterpraise应用程序，这个EJB jar被添加到我的耳中。我没有任何编译错误，并且构建也通过maven成功。我确实已经将log4j jar文件作为依赖添加到此项目中。 请你帮助我在哪里和我错过了什么？
答案 0 :(得分：2)
部署的应用程序只有两种方法可以找到依赖jar。
1在EJB jar本身中正确包含它。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，它将可供服务器实例上部署的所有应用程序使用。
如果您使用的是Maven，请确保未设置log4j依赖性以使用
<scope>provided</scope>
选项。此选项不包括打包应用程序中的log4j jar。
