Yes. We can achieve this either using JavaScript or action mapping. If you use JavaScript, we can use the 'location.href' to go one page to other page.If you use action mapping, we can use the findForward method to go one page to other page.

Can i have more than one ActionServlet class file in my application?
sriragv
- Nov 28th, 2009
We can have more than one Action Servlet but Struts controller follows the front controller design pattern. As per this pattern we will have only one controller. Designing more than one action servlet is breaking the rule of design pattern.

Yes, but?stuts-config definition are stored in the application scope with a key so when the second definitions comes in the web.xml, the second struts-config overrides the previous one.

When you have a global forward and a local forward in struts-config.xml, which one will be called
Kola.Nareshreddy
- Nov 19th, 2009
By default precedence is given to the local forward. Global forward is like global and available always, but if you don't want that global forward then very well you have to add a local forward. It's just like Local and Global variables.
muvvalasrinu
- May 28th, 2009
Local Forwards always override Global Forward names. So for example, if you have a Global Forward with the name shoppingCart and a local Forward with the same name, the local Forward takes priority. If a local Forward can not be found then Struts will try to find the same name among Global Forwards.
