Re: Cannot find ActionMappings or ActionFormBeans collection

Eddie Bush Sun, 12 Dec 2004 22:22:26 -0800

In order to have a request properly setup, you need to be going through the controller. To go through the controller, you need to be viewing an action instead of a JSP page. Try invoking an action that uses the template and see if the problem persists.

You can't expect Struts to set things up for a page it doesn't know you're requesting, and it can't know you're requesting the page unless you go through the controller :-)

Good Luck,

Eddie

Hi David,
That error is displayed while I am loading my Template.jsp itself.
http://localhost:8080/test/Template.jsp Not able to see the GUI itself.

Is that error at start-up or when you are invoking an action by going to a
Struts *.do action through a URL?

Hi Sunny, Thanks for the reply. The classpath is set right and my struts-config.xml file looks the same way as you posted, I just removed the un necessary tags. Any ideas now?
