Hi all, My apologies, my Tomcat server version is Apache Tomcat 8.0.29 Server. The JDK is 1.8
Hope to get some advice what went wrong in regards to the No connection specified with project.

If you have a ResourceLink in context.xml, it means that your Resource element must go into GlobalNamingResources element of conf/server.xml file. http://tomcat.apache.org/tomcat-8.5-doc/config/globalresources.html BTW, you should not modify conf/context.xml file. It is the defaults file shared by all web applications. (Modifying it is a common configuration mistake).
