Re: Struts 2 : application-wide values initialization.
You can do the same with an application scope bean using spring . Create
a simple pojo that initializes values on the constructor. Then add an
entry to the applicationContext.xml file :
beans
bean id=myComp class=org.components.MyComponent singleton=true/
/beans
Then in your java action file that you wish to have access declare :
private MyComponent myComp;
and create a setter :
public void setMyComp(MyComponent myComp) {
this.myComp = myComp;
}
Now you can get and edit these default values from your action.
I do not know if this is the best way to do it and please excuse if i
have any typing mistake (it should be fine though...).

In Struts 1, we were having an init servlet to load the application-wide
properties like dropdown values (from property files) into application
context and accessing these within JSP. Is there a better way of doing
this in Struts 2, and do we require an initialization servlet at all ? .
The ServletContextListener is called when the ServletContext is
starting up and shutting down. It's designed to let you do one time
configuration and initialization. You have access to the
ServletContext so that you can put things in the Application scope.
Sorry, I thought that's what you were asking for.

Re: Struts 2 : application-wide values initialization.
Another option is to subclass the Struts 2 FilterDispatcher to perform
initializations:
public class YourAppDispatcher extends FilterDispatcher {
public void init(FilterConfig filterConfig) throws ServletException {
super.init(filterConfig);
// your initialization code here...
}
}

Struts 2 : application-wide values initialization.
Hi, In Struts 1, we were having an init servlet to load the application-wide properties like dropdown values (from property files) into application context and accessing these within JSP. Is there a better way of doing this in Struts 2, and do we require an initialization servlet at all ? . Thanks, Joseph
