You can right-click on this project and go to Debug As or Run As then select
            "MyEclipse Server Application". MyEclipse 6.0 and later will automatically deploy
            the application to the MyEclipse Tomcat Server, then start it up and open
            a browser window for you to the index.jsp page.

Why would you try to use the tag libraries from 1.3 in a 1.1 app?! Why would you use 1.1 at all, for that matter?

What Struts lib(s) are you deploying, and where are they located in your app hierarchy?
