Struts2 - How to save an object through ApplicationAware.

Hi Guys,

I would like to ask if there is a possibility that I could save my objects using the ApplicationAware upon startup of my server by not using it as an action class?

My follow question is, could I implement ApplicationAware together with ServletContextListener so that I could have it saved upon startup of server?

I've tried creating a class like this one, but application.put("languageList", languageList); gives me NullPointerException everytime I start the tomcat.



web.xml snippet


I just need the object languageList to put it in <s:select> tag.

Thanks,
Paul

Why are you using ApplicationAware for this?? Just create a ServletContextListener and put the attribute in the ServletContext object...

Ankit is correct. ApplicationAware is meaningless outside of a Struts 2 interceptor stack.

Thanks David and Ankit. I got it working now using the ServletContext object, and could see the value in my JSP.
