The native Struts2 solution would be to use an interceptor, or to piggy back on an interceptor that already exists. Writing your own interceptor is not difficult
* http://struts.apache.org/2.x/docs/writing-interceptors.html and I would suggest that everyone at least try writing one interceptor once :) Another way to go is to piggy-back on an existing inceptor, like SessionAware or ModelDriven. The interfaces describe a setter or a getter. When that method is called, it becomes an event, so you can call your own singleton or what-have-you to acquire the bean as save it to the Action. For example, here's a SessionAware setter that exposes a User object stored in the session as a property. @SuppressWarnings("unchecked") public void setSession(Map value) { session = value; // setUser when session available Object object = value.get(USER_KEY); if (object==null) { User myUser = new MyMemoryUser(); setUser(myUser); setTask(INSERT); } else { setUser((User) object); setTask(UPDATE); } } In turn, the ModelDriven getter can call getUser: public Object getModel() { return getUser(); } If SessonAware wasn't locating the user property, we could inject some could here to acquire and cache the property. (Though doing it advance is a much better approach!) We could really use a good description of ModelDriven on the website. For now, the best resource would be Ian's Getting Started or WebWork in Action. > I wish there were some more books out there on Struts2 ... I'd > read them first before asking here. Today, WebWork in Action is still the best Struts 2 book available! But that will start to change as Kurniawan's book and Roughley's new books ship this month and next. Anyone who is interested in Struts 2 books should pre-order one or both of these now, to encourage other authors. * http://struts.apache.org/2.x/docs/home.html#Home-Books -- HTH, Ted <http://www.husted.com/ted/blog/> Meet me at ApacheCon US 2007: * http://us.apachecon.com/us2007/program/talk/1883 On 10/2/07, Tom Holmes Jr. <[EMAIL PROTECTED]> wrote: > I've been playing with Struts2+Spring2 beans+Hibernate and that all > works very well. > > So, now I am trying something simpler ... so consider this a new > web-project altogether with just Struts2 ... no Spring2 and no Hibernate. > Basically, I want to call a pre-Action action that loads a bean into a > session and then calls a JSP page ... simple right? > > So, I am presuming that in the struts.xml file I have an action like: > <action name="start" method="execute" class="com.me.path.me.again.MyAction"> > <result name="success">/mypage.jsp</result> > <result name="error">/myerror.jsp</result> > </action> > > Is that all I need?
