Re: IS struts 2 websphere compatible?
YES, you can backport struts 2 core and dependancy jar files to JDK 1.4 and use them.

Re: Custom validation with Struts2
If Integer Range Validator does not work for you then you shoud consider
regular expression validation for same, its can be done by restricting
number of digits and allowing only numeric characters.
Here is an example of similar problem

Struts 2 Integer Validation
fil78 wrote:
Hello everybody,
I need to validate only 1 field on the jsp. It value should be between 1
and 99. Initially I started to implement through int validation but it
seemed to go wrong - it works with some limitation - maximum value should
not exceed 1000 or something like that. I am trying to implement
validation through overriding validate() method. I use tiles together with
Struts 2.0.11. I could not tune it to work correctly. Could someone help,
please?
Here are my snippets:
Struts.xml:
action name=EmployeeCard
class=com.tsystems.tintra4.actions.EmployeeCard
interceptor-ref name=i18n /
interceptor-ref name=roles
WTT_CARDS_EDITOR
/interceptor-ref
!-- interceptor-ref name=workflow/--
interceptor-ref name=workflow/
result type=tiles
name=SUCCESSdef_page_employee_card/result
result type=tiles name=input
def_page_employee_card
/result
/action
Jsp:
%@ page language=java contentType=text/html; charset=UTF-8
pageEncoding=UTF-8%
%@ taglib prefix=s uri=/struts-tags %
!--Reference to the Employee profile--
div
s:url id=url_fio action=GetEmployee includeParams=none
s:param name=employeeIds:property value=%{EmpNo}//s:param
/s:url
s:a href=%{url_fio}

/s:a
/div
br/
!--Adding new card--
s:if test=addCard == true
s:text name=card_adding_proccess/s:text
s:fielderror/
s:form method=GET validate=true
s:textfield name=cardNo
label=%{getText('card_add_edit_field')}/s:textfield

s:hidden name=editCard value=%{true}/s:hidden
s:hidden name=addCardFinal value=%{true}/s:hidden

/s:form
/s:if

s:hidden name=editCard value=%{true}/s:hidden
s:hidden name=editCardFinal value=%{true}/s:hidden
s:submit value=%{getText('button_submit')}/
/s:form
/s:if
JAVA Action:
public void validate() {
request = ServletActionContext.getRequest();
String tmp = ;
try {
tmp = request.getParameter(cardNo);
Integer i = this.getCardNo();
if (tmp != null tmp.length() 0) {
int tmpInt = Integer.parseInt(tmp);
this.setCardNo(tmpInt);
System.out.println(Card no (validation) = +
cardNo);
if (cardNo 1 || cardNo 99) {
addFieldError(cardNo, Must be int);
System.out.println(INPUT...);
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
Thanx a lot.

RE: Struts 2 onchange event to get values from databases

Thanks for your quick response.
I have created Jsp and action and struts.xml. you are mistaken
me(imlazy), i'm not
asking the code for my requirement.
I want to display the userdetails, at the time of Onchange
event. I don't want
to use javascript. My details are getting from db. If you provide some
examples in AJAX
than it will be helpful.

Dude,
Here is an example which shows how you can populate a drop down using
AJAX

Hope this helps
Regards,

Me thinks you're lazy for not going through the tutorials supplied on the
documentation site: http://struts.apache.org/2.x/docs/home.html
You'll have to set up 'n struts.xml file (saved in WEB-INF/classes
folder)
that looks something like this:
!DOCTYPE struts PUBLIC
-//Apache Software Foundation//DTD Struts Configuration 2.0//EN
http://struts.apache.org/dtds/struts-2.0.dtd;
struts
!-- constant name=struts.devMode value=false / --
constant name=struts.enable.DynamicMethodInvocation value=false
/
package name=mypackage extends=struts-default
action name=display class=com.imlazy.DisplayUserDetails
resultuserdetails,jsp/result
/action
/struts
You'll have to implement the action class, which has the values you want
to
pass to your jsp declared with getters and setter for each of them
(JavaBean
style):
package com.imlazy;
import **;
@SuppressWarnings(serial)
public class DisplayUserDetails extends ActionSupport {
private String userName;
private String userAddress;
private ListString userNameList;
// etc
@Override
public String execute() throws Exception {
// HERE YOU DO YOUR DB ACCESS AND WHATEVER TO POPULATE YOUR FIELDS
}
public String getUserName() {
return userName;
}
public void setUsername(String userName) {
this.userName = username;
}
// Other getters and setters
}
And finally your jsp that will be displaying the fields:
%@ page contentType=text/html;charset=UTF-8 language=java %
%@ taglib prefix=s uri=/struts-tags %
html
head
titleUser Details/title
/head
body
s:form
s:combobox label=Users list=HERE YOU MUST DEFINE THE LIST
headerKey=-1 /
s:textfield key=userName
!-- HERE FOLLOWS YOUR OTHER FIELD --
/s:form
/body
/html
This is just touching what you need to do and know. Most important is to
understand. Go through the tutorial, know what you need to get an action
to
display what you want to display (choose one user and just display the
values for that user). Only then start thinking about AJAX and how you
should be changing what is displayed as the combobox is changed.

I am very new to Struts 2 and Ajax. If u have any samples please send

Subject: RE: Struts 2 onchange event to get values from databases
Hi Johnson,
I'm no Struts expert but from my experience you have two ways of
implementing what you want to achieve.
1. You can populate your dropdown box and have the fields empty. On your
element you can set the onchange to call a javascript function that
calls
the same action, but passing it the content of your combobox, to do your
database lookup on the server side and then pass the info to your
userdetails.jsp where you can set your fields.
2. You can use AJAX to do the call asynchrononously, that is the value
is
passed to an action on the server and without the values passed back and
filled into your fields. Nowadays you'll find plenty of tutorials and
examples out there. Check out the following:
http://struts.apache.org/2.x/docs/ajax.html
(the official Struts AJAX guide)
http://www.roseindia.net/struts/struts2/struts2ajax/index.shtml
(easy login example)
http://www.javaworld.com/javaworld/jw-08-2007/jw-08-ajaxtables.html?fsrc=rss
-index
(although is a rather tough example to follow if you're new to AJAX)

(showcase examples)
