Hi, What kinds of linking and configurations are required by you. Struts classes, forms resides in the .war part of the .ear application.U have to give the struts-config file declaration in the web.xml file. As an example: <init-param> <param-name>config</param-name> <param-value>/WEB-INF/struts-config.xml</param-value> </init-param> Rest the invocations of the backend is similar as without struts.
Struts is a standard Web Application, there is no "installation" necessary to use within most Application Servers. However, there is quite a bit of configuration required within a Struts application. I suggest you check out the Struts Project Page and work your way through the Struts User Guide.
