Re: ValidatorForm.getServlet() == null !!
Hi Albrecht, The ActionServlet in an ActionForm is a private member with no accessor methods. So, try this in your form: this.servlet.getServletContext(); HTH, Curtis Albrecht Berger wrote: Hello, I need the ServletContext in one of my forms, which I'm trying to get with : getServlet().getServletContext() Unfortunately I get a NullpointerException, because the servlet is null.

Re: On usage of Resource Bundle
Hi Ashutosh, The safe bet is to have the default in both config files. It should be relatively easy (a couple 2-3 deployments) to test whether or not you need it in both places.

My web application is divided into two sub modules i.e. basically the application uses two struts configuration file. I'm going to have only one resource bundle. Now, is it necessary to have tag configured in both the struts configuration file? Will providing the configuration at one place won't suffice? Since, MessageResources objects are created by the controller i.e. ActionServlet and saved in the ServletContext using either a generic key Globals.MESSAGES_KEY or the key provided as part of the 'key' attribute. So, I feel it should be accessible to the Action classes, which are part of the other struts configuration file too. Is my understanding correct? Anyone who can provide me a better insight on the same will be useful.

Re: Extending Request Processor to append request parameter

Therefore I wanted to append a Parameter to each request and add a unique number so that the server would not look in the cache. (Having the user change their browser caching mechanism isn't an option). I see where I can SEE the different request parameters, but where can I append a new parameter?

Re: Checkbox not checked
Hi Wendy,
I'm not exactly sure, but I'm a tad suspect of your 'c:if test' expression. It
looks suspiciously like a Python "boolean" test for the object's presence.
AFAIK, in JSTL one needs to be more explicit as to what value (or lack thereof)
when testing...
Unless, of course, it's just a typo in your email...;-)

Before I go back to the Action and create a separate Map to hold only
the "active" accounts based on the selected year, does anyone think this
ought to work the way it is?

Re: Error Start Tag Exception
Hi Betty, I think you need to set the 'message' attribute to false here, as the tag is looking for an ActionMessage instance, not an ActionError one (which is what you get in the loop created by the tag).

Re: problems w/ logging.. again
Hi Adam, Insofar as I've seen it with JBoss, yes: the application-scope log4j config files have no effect. If you're using ant, it'd be fairly simple to write a task which copies your app's log4j.xml to the appropriate server/conf directory. And no, you shouldn't have to bounce the app server. It should pick up your config changes while it's running. Curtis Adam Levine wrote: Curtis: Thank you for the insight. I'll be sure to try this out this evening. Am I correct to assume that app-specific log4j config files will not be used (as in, to append/make use of the global config), and that anytime I want to change the logging for a specific app I have to make a global change and bounce the entire app server?

Re: Dependent Drop Down Boxes
Hi David,
I'm in process of cobbling together something like this using Tiles. I've
defined a generic selector widget as a jsp, then subclassed it in the
tiles-defs.xml n times, with each new definition having its own controller which
is responsible for populating the selector with context-specific data. These can
be inserted as a Tile inside an html form. In the definitions I have an
"onChange" attribute which is a string representing a Javascript function
("return document.forms[0].submit();", for example). Controller B uses the
request param from selector A to populate selector B's data. Use an Action class
for your form action, forward back to the input, etc. Seems promising so far.
If you want a straight jsp/Javascript approach Danny Goodman has an excellent
solution in his "Javascript & DHTML Cookbook." Very clean & simple to use, and
you can populate your options dynamically inside a c:forEach loop. I found it
easier to implement than Matt Kruse's library, but then again I'm not the
sharpest pencil in the box...;-)
HTH,
Curtis

Hi I was wondering if anyone knew of any taglibraries or javascript related

drop down box 1 choses the options you get in drop down box 2. Ideally this
would not require a refresh of the browser. An example of this is
carpoint.msn.com where you chose the vehicle manufacturer and in the next
box it shows you only cars made by that manufacturer. They are using
javascript coded in house... I was wondering if there is an open source
project or solution to work with this.
