There is no such version as "Tomcat 1.8". I assume that you meant some
version of Tomcat 8.0.x.

The META-INF/context.xml file of a web application must have only one
of <Resource, ResourceLink> elements with the same value of "name"

If you have a ResourceLink in context.xml, it means that your Resource
element must go into GlobalNamingResources element of conf/server.xml

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).
