The Application scope

getting an object that was placed in application scope (done in Struts Action):

In your Struts Action Class (inherits from org.apache.struts.action.Action) , like was done here just create the following method:

       protected Object getApplicationObject(String attrName) {
         return servlet.getServletContext().getAttribute(attrName);
     }

setting an object into application scope can be done by implementing a struts plugin.

Create a class that extend org.apache.struts.action.PlugIn:

public class myPlugin implements org.apache.struts.action.PlugIn {

  public void init(org.apache.struts.action.ActionServlet servlet,
   ModuleConfig applicationConfig) throws ServletException {
 
     setApplicationObject(servlet, "object1", "YES");
    
    
}

protected void setApplicationObject(
   org.apache.struts.action.ActionServlet servlet, String attrName,
   Object obj) {
      ServletContext context = servlet.getServletContext();
      context.setAttribute(attrName, obj);
}
}

Don’t forget to define your plugin in struts config file:

<

plug-in className="myPath.myPlugin"/>

Lastly, remember the application scope is multithreaded
