I am extending ActionServlet to override init() i order to make a the database connection with oracle. Previously I was making teh connection in each request, in the overridden action class and my application was working fine. But I think , the databse connection should be made once at the
servlet initialization, and not at each request.
My overridden Action Servlet is :
my action class is :
web.xml is :
struts-config.xml is :
and the exception that i am getting is :
