Where can I find taglibs
I want to write a web app with jsp/struts. I know that there should be a struts tag library for this. Where can I find it? Thanks, -Paul - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Validation Help
I have a question. I have decided to use the vaildation framework to do the validation in my web app. I have created a validation.xml file, and a vaildator-rules.xml file. I noticed in books about struts that I have there is a properties file associated with the vaildation. Am I right? If so I add it to my struts-config file, right? -Paul Glen Mazza wrote: http://www.objectsource.com/Struts_Survival_ Guide.pdf, Chapter 5.

Question about DispatchAction
I am writing a web app that gets information from a user (first and last names, and their address (street, city, state, zip) ) and the user has the option to sort the data. Based on direction(ascending or descending) and what to sort by. Either first or last name. Now here is my question, I have four Action classes in my web app. I have them in separate files. Since I am just beginning to learn Struts I was unaware of the DispatcherAction class. Now that I am aware of it I am going to use it. There is one question I have though, What class does my dispatchAction class extend from? I assume its an extension of some class. Also, I'm not sure if this is the right place for this but I am having some object reference problems. What's happening is that when I fill up the information form with the name and address, I then save those values to a bean. Once I have all the values in a bean I then save that bean object into a vector. Now it seams that when I insert a new name into the vector the first position of the vector is overwritten by the new info that is being saved into the second position. However when I added a third name I don't have that same problem. It just enters in correctly. Now when I go and try and sort the contents of the vector there seems to be a new object reference. So I guess my question is, Will the Dispatcher class help with this object reference problem? -Paul - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Having ttruble with actions and buttons
ok here is what I am talking about. I have a form that takes in first
name, last name, street address, city, state and zipcode. When I press
on the button to enter that information into a database. I want the
page to reload with clear input fields.

What do you mean "clear out" and what do you mean by "reload"? If you
need a stateful component to obtain user data, and to be able to to
redisplay the page with error messages, and to store intermediate
data, and to correctly process Refresh and Back buttons, you might
want to take a look at the class that I put together last week:
http://struts.sourceforge.net/strutsdialogs
If you totally against storing data in the session, this class is not
for you, though ;-)

P.S. Damn, that download counter did reset, when I updated the zip :-(
P.P.S. The live samples are not available right at this moment, the

This code reeks of code smell, regardless of any other issues,
especially if you have to do something similar in any other action.
This is, more or less, what DispatchAction (?) was created for. Here
you've duplicated controller logic inside an action, which is really
supposed to be a target of the controller.
So here you are expecting forwards named "enter", "default", and "sort".
menu
onchange="menu.action.value='enterInfo'"
$text.get("menuEnter")
enterInfo
onchange="menu.action.value='default'">$text.get("menuDefault")
default
onchange="menu.action.value='sort'">$text.get("menuSort")
sort
Okay, so that looks good.
Have you done a sanity check with a plain 'ol action with a forward to
a JSP like Frank suggested?
Have you put in logging statements to make sure that the action
parameter is what you expect it to be when you hit your action?
Have you been able to get _any_ Velocity file to render, i.e., hit one
without going through Struts? An the related Have you checked on the
Velocity list to make sure you have the VelocityViewServlet set up
properly?
Have you checked the log files for error messages?

Re: Having ttruble with actions and buttons
Here is my MenuAction.java
package actions;
import org.apache.struts.action.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.Arrays.*;
import java.io.*;
import forms.*;
import beans.InfoBean;
import logic.DB;
public class MenuAction extends Action
{
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException
{
String action;
HttpSession session;
DB data = new DB();
InfoBean sorted [] = new InfoBean [data.getInformation().size()];
try
{
session = request.getSession();
action = request.getParameter("action");
if(action.equals("enterInfo"))
{
return (mapping.findForward("enter"));
}
else if(action.equals("default"))
{
sorted = data.createSortedArray("ascending", "first");
data.removeInsert(sorted);
data.createContext(sorted);
return (mapping.findForward("default"));
}
else
{
return (mapping.findForward("sort"));
}
}
catch (Exception e)
{
e.printStackTrace();
}
return (mapping.findForward("menu"));
}
}
I am also including part of the webpage source file incase the problem
is in there and its a html error.
$text.get("menuEnter")
$text.get("menuDefault")
$text.get("menuSort")
The $text variable is a varable that is defined in the velocity tools
package. The variables are defined in a properties file I defined. When
displayed on the web the $text variable is exchanged with the mapping in
the properties file.

How your app is configured is completely up to you... there are no rules
per se (there's some commonly-accepted pattersn though). You might have
10 Actions for a single page (reasonable in some cases), or one Action for
10 pages (probably not a good idea generally), or one per page (most
common I'd say), or something else I haven't thought of.
I'm guessing, based on the config you posted, that you are submitting a
form to /Menu when any of a number of menu items are clicked? Then in the
Action you are determine which was clicked and forwarding to the
appropriate Velocity template? If so, that's a reasonable approach...
some would say you should probably use a DispatchAction, but it's more a
matter of what you prefer than what is right or wrong.
Now... why you aren't seeing the JSP... I think you want to solve that
before anything else... The first thing to do is be sure what forward is
being returned... As a matter of fact, how about posting your Action's
code? I assume it isn't too big... There might be something obvious that
I or someone else can point out right away... You either have something
configured wrong, or the Action's code is wrong... Are you sure the Action
is being reached at all? If so then most of your configuration it
obviously correct, the only remaining point could be the forward
declarations. Nothing stands out as wrong to me though, so seeing the
code might help.

if you get to it, then the problem is in the Velocity side of things
