Question

我正在尝试在weblogic 12c（支持Java 6,7,8）中部署我的旧应用程序，但是每次显示java.lang.IncompatibleClassChangeError：实现类时，我都无法理解什么是确切的问题，如何解决这个问题，有人可以帮助我吗？在weblogic 10（支持Java 4,6,7）中，已成功部署

Answer 1

我可以看到您的应用正在使用Jersey框架。请参考此页https://docs.oracle.com/middleware/1213/wls/RESTF/use-jersey20-ri.htm#RESTF290

如果仍然遇到问题，请尝试使用Jersey框架的更新版本。在这种情况下，请注意，您必须修改web.xml文件以起诉正确的servlet类：

<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
