weblogic - 在 Weblogic 12c 上部署 Designer.war

Question

部署designer.war（对于 DRools）到 WebLogic 12c 时，会引发以下异常：

Caused by: javax.servlet.ServletException: [HTTP:101249][ServletContext@2539776[app:designer module:designer.war path:null sp
ec-version:3.0]]: Servlet class org.apache.catalina.servlets.DefaultServlet for servlet DirectoryListingServlet could not be
loaded because the requested class was not found in the classpath .

可以建议designer.war在 Weblogic 12c 上的正确部署步骤吗？
