Servlet action is not available - Help please

Question

Hi, I'm new to jsp and struts. But I'm starting creating a simple entry form and saving the data in a database.
I'm using netbenas 5.0 and created my project from the struts wizard.
I had everything working fine, but now I'm getting the error above.
I tried to search for an answer for this problem and I know that the class "org.apache.struts.action.ActionServlet" is accesible to Tomcat.
So I don't know what else could be wrong. The struts-config and web.xml files are almost "netbeans-only-made", so I couldn't find where
"I" may have inserted wrong entries.
My struts-config.xml :
<?xml version="1.0" encoding="ISO-8859-1" ?>

Answer 1

503 Service Unavailable
The server is currently unable to handle the request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay. If known, the length of the delay MAY be indicated in a Retry-After header. If no Retry-After is given, the client SHOULD handle the response as it would for a 500 response.
Note: The existence of the 503 status code does not imply that a
server must use it when becoming overloaded. Some servers may wish
to simply refuse the connection.
