RE: Please Help - ClassCastException
I've been responding to your questions here and at JavaRanch on this
subject.
It seems like you are missing the point of DynaActionForms.
Please read 4.3 and 4.4 of the user guide.

Subject: RE: Please Help - ClassCastException
Allow me to ask three more questions:
1. If I want to reset some specific text fields when
the JSP is re-displayed, do I code the PostForm.java
like this (please confirm):
code:
-
import org.apache.struts.validator.DynaValidatorForm;
import org.apache.struts.action.ActionMapping;
import javax.servlet.http.HttpServletRequest;
public class PostForm extends DynaValidatorForm
{
public void reset(ActionMapping mapping,
HttpServletRequest request)
{
super.reset( mapping, request );
set( receiver, new String() );
set( sender, new String() );
}
public PostForm () {}
}
*** Why not just use the intial attribute of the form-property
element?
---
2. if I want to reset all the text fields when the JSP
is re-displayed, do I code like this (please confirm):
code:
---
import org.apache.struts.validator.DynaValidatorForm;
import org.apache.struts.action.ActionMapping;
import javax.servlet.http.HttpServletRequest;
public class PostForm extends DynaValidatorForm
{
public void reset(ActionMapping mapping,
HttpServletRequest request)
{
initialize( mapping );
}
public PostForm () {}
}
--
*** Why not just use the intial attribute of the form-property
element?
3. What is the difference between
code:
---
form-bean
name=postForm
type=package.package.package.PostForm
form-property
name=receiver
type=java.lang.String/
form-property
name=sender
type=java.lang.String/
/form-bean
---
AND
code:
--
form-bean
name=postForm
type=org.apache.struts.validator.DynaValidatorForm
form-property
name=receiver
type=java.lang.String/
form-property
name=sender
type=java.lang.String/
/form-bean
---
Thank you very much.
*** The second one makes sense. Why do you need the PostForm
class?
see my answer to a similar question of yours at JavaRanch
http://saloon.javaranch.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topicf=58t=
001820
Here is a snippet of some tutorial I am working on that might help.
DynaActionForms are universally loved and hated. In teaching, consulting
Struts and developing with Struts, I have found that DynaActionForms are
either embraced or rejected. The idea behind DynaActionForms is that instead
of creating an ActionForm per form, you instead configure an ActionForm per
form.
Advantages of DynaActionForms:
Some folks feel creating an ActionForm class for each HTML form in your
Struts application is time-consuming, causes maintenance problems, and is
frustrating. With DynaActionForm classes you don't have to create an
ActionForm subclass for each form and a bean property for each field.
Instead you configure an DynaActionForm its properties, type, and defaults
in the Struts configuration file.
snip
To configure a DynaActionForm in struts-config.xml, you use a form-bean
element as with normal ActionForm. The type of the form bean must be
org.apache.struts.action.DynaActionForm or a derived class. You then add
form-property elements to declare the properties of the form.
To use a DynaActionForm add the following to form-beans element (example):
form-bean name=userRegistrationDynaForm
type=org.apache.struts.action.DynaActionForm
form-property name=userName
type=java.lang.String /
form-property name=email
type=java.lang.String /
form-property name=password
type=java.lang.String /
form-property name=passwordCheck
type=java.lang.String /
form-property name=firstName
type=java.lang.String /
form-property name=lastName
type=java.lang.String /
form-property name=phone
type=java.lang.String
initial=(520) /
form-property name=fax type=java.lang.String /
form-property name=page
Struts Tiles Tutorial (free Struts training)
Master the Struts Tiles Framework Tutorial (Dec. 2003) http://www.arc-mind.com/downloads.htm The Tiles framework makes creating reusable pages and visual components easier. Developers can build Web applications by assembling reusable tiles. You can use tiles as templates or as visual components. In some respects, the tile layout is like a display function. First you pass tile layout parameters to use. The parameters can be simple strings, beans, or tiles. The parameters become attributes to the tile and get stored in the tile's tile scope. For its part, the tile scope resembles page scope, and is less general than request scope. The tile scope lets the tile's user pass arguments (called attributes) to the tile. Definitions let you define default parameters for tiles. Definitions can be defined in JSP or XML. Definitions can extend other definitions similarly to how a class can extend another class. Moreover, definitions can override parts of the definition it is extending. The Tiles framework includes its own RequestProcessor to handle tile layouts as ActionForwards. Thus you can forward to a tile definition instead of a JSP if you install the Tiles plug-in. If you are using Struts but not Tiles, then you are not fully benefiting from Struts and likely repeat yourself unnecessarily. The Tiles framework makes creating reusable site layouts and visual components feasible. In this tutorial you will cover the following: The Tiles framework and architecture How to build and use a tile layout as a site template How to use tile definitions both in XML and JSP How to move objects in and out of tile scope How to work with attributes lists How to nest tiles How to build and use tile layouts as small visual components How to subclass a definition How to create a controller for a tile How to use a tile as an ActionForward Rick Hightower Developer Struts/J2EE training -- http://www.arc-mind.com/strutsCourse.htm Struts/J2EE consulting -- http://www.arc-mind.com/consulting.htm#StrutsMentoring - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Querystring builder
hi,
Yes, i was referring to copyProperties().
The problem really gets complex if you have nested objects.
and i doubt if there is any readymade solution to the problem you are
facing. but with very little effrots you can do this
You can make one and for all. Doesn't seem to be a tough job althought bit
lengthy :-)
Ok, allow me to get my hands dirty!! and I am not sure if this works with
collections as you may want. You ca try with collections yourself.
Say you have something like
class A (with corresponding gettter and setter)
{
private B b;
private String str;
}
class B (with corresponding gettter and setter)
{
private String str;
}
All you need to do is
A a = new A();
a.setStr(navjot);
B b = new B();
b.setStr(singh);
a.setB(b);
Map m = new HashMap();
Then call BEanUtils.copyProperties(m,a);
you will get a map filled with key-value pairs
str=navjot
b.str=singh
pass this to some function like.
String getQueryStirng(Map m)
{
Iterator nvPairs = m.keySet().iterator();
StringBuffer nvString = new StringBuffer();
String key;
while(nvPairs.hasNext())
{
key = (String) nvPairs.next();
nvString.append(key + =);
nvString.append(this.getString(key) + );
}
String nv = nvString.toString();
if(m.keySet().size() != 0)
{
return nv.substring(0,nv.lastIndexOf());
}
return nv;
}
My this function may not be efficient and does the job you want.
and HURRAY!! you will get QueryString like
str=navjotb.str=singh
hope this helps

Hi Navjot,
I have been working with the BeanUtils things on this problem.
Are you referring to the 'describe' and 'populate' methods? That's what
I've been working on.
I am looking for yet a simpler way to do this. I should say, I wonder if
there's an easier way to do this.
Let me explain a bit on the situation.
Multipage form. The form bean contains other value objects, and these
value objects have Collection properties, pointing to another set of
Value Objects.
That is, in my original formbean:
public MyEJBValueObject getXXX(){...}
public void setXXXs(MyEJBValueObject e){...}
In the MyEJBValueObject.java, I have:
public Collection getYYYs(){...}
public void setYYYs(Collecton c){...}
And the collection YYY actually is a arraylist of AnotherEJBValueObject
With this kind of structure, it's quite tedious to build the
QueryString,
Is that right? I suppose I have to iterate thru the Map described by
BeanUtils and go into further levels, and describe again.
The worst part is, I don't want to build the 'Form elements' myself.
That is,
I have to come up with indexed/mapped/mixed name, like,
SALES.ITEMS[2].DISCOUNT['MONTHLYSPECIAL'].DISCOUNTRATE
Do I have to do that manually?
Thanks.
Patrick.

RE: Custom Link Tag
Thanks Nico.
However, I'm facing a problem with using my custom linktag.
I am trying to specify the href attribute from which I shall get the
path by using:
dtag:dlink href=/sample.html showAlways=truetest tag/dtag:dlink
However, my jsp is giving me the error: Error(12): Attribute: href is not a
valid attribute name
I suspect that since it is looking up the tld which I've written, which
doesn't have the href attribute, that's causing the error.
Now, my tag class extends the struts html LinkTag, but how do I get it (my
TLD) to include the attributes of the LinkTag in the original
struts-html.tld.
Thanks.

The functionality of the MyLinkTag is captured in the following code
snippet:
***
HttpServletRequest request = pageContext.getRequest();
ActionMappings actionMappings =
(ActionMappings)request.getAttribute(Action.MAPPINGS_KEY);
String path = getHref();
ActionMapping actionMapping = actionMappings.findMapping(path);
String[] roleNames = actionMapping.getRoleNames();
boolean userInRole = false;
for(int i=0; iroleNames.length(); i++)
{
userInRole = request.isUserInRole(roleNames);
if(!userInRole){
if((alternateLink != null) !(.equals(alternateLink))){
setHref(alternateLink);
}
else{
if(showAlways){
setDisabled(true);
}
else{
//don't show the link
return SKIP_BODY;
}
}
}//end if !userInRole
}//end for loop
***
The problem is I don't know where to place this code i.e. in which
method:
doStartTag() or doEndTag() or doAfterBody() or any other??
What method should I override??
And what should be the return [integer] values??
Thanks in advance.

Re: Custom Link Tag
You have to copy/paste extended taglib description in your custom tld.
You should write a simplest custom tag that includes it's body into response (the way
logic: tags do) on some
application-specific conditions, and use it this way :
myTag:isUserInRole path=/sample.html
html:link href=/sample.htmltest/html:link
/myTag:isUserInRole
Your tag will be reusable for various presentation items.
Nico.
Thanks Nico.
However, I'm facing a problem with using my custom linktag.
I am trying to specify the href attribute from which I shall get the
path by using:
dtag:dlink href=/sample.html showAlways=truetest tag/dtag:dlink
However, my jsp is giving me the error: Error(12): Attribute: href is not a
valid attribute name
I suspect that since it is looking up the tld which I've written, which
doesn't have the href attribute, that's causing the error.
Now, my tag class extends the struts html LinkTag, but how do I get it (my
TLD) to include the attributes of the LinkTag in the original
struts-html.tld.
Thanks.
Sanjay

Nico,
Thanks for your response.
However, what will happen to the existing code in the doStartTag of the
org.apache.struts.taglib.html.LinkTag?
Because I will still need the existing functionality of the
org.apache.struts.taglib.html.LinkTag as well !!
Should I make a call to the super.doStartTag()?
Please advise.
Thanks.

Announce: JPlates 3.0.1 released - object-oriented template processing for Java, JSP, and Struts
JPlates Inc has announced the general availability of JPlates 3.0.1. JPlates 3.0.1 adds template processing to Java, providing fully compiled, object-oriented template processing with template objects and template methods. JPlates dramatically improves productivity for Java and JSP and Struts developers. A free evaluation version is available. The new features in JPlates 3.0.1 include support for using JPlates template components with JSPs, even more support for Struts applications, dynamic class and configuration reloading for JPlates and Struts, enhanced Ant integration, and a new template visualization tool. For more information and JPlates examples, visit http://www.jplates.com. JPlates 3.0.1 syntax extends Java 1.4 syntax with JPlates template methods. Template methods are called just like other methods, but use JPlates template syntax for their method bodies. The result is callable, executable templates. The template method syntax combines template literal text with: substitution and i18n expressions, control flow statements and method calls, variable declarations and assignments, and output format control statements. JPlates classes are compiled into Java to ensure 100% compatibility with Java. The JPlates compiler is fast and robust, and maintains line numbers between the JPlates source and the generated Java to support easy debugging. The JPlates 3.0.1 runtime provides high performance template processing support for Servlets, Struts, JSP, J2EE, and J2SE applications. JPlates 3.0.1 offers the most usable, flexible, and powerful technology for dynamic content generation on the web, for XML transformation, for source code generation, for generating personalized email, or for any other application involving template-based processing. Use JPlates 3.0.1 along with or in place of JSP, XSLT, and other template processors, wherever you generate stylized text, whether in a web-application, a code-generator, or any other kind of Java application.
Filling select with options and getting description from ids: Providers
Using Struts tags, you do this for creating a select filled with options tags: html:select property=idDocument html:options collection=documents property=id labelProperty=descrip/ /html:select In this case, you should create a collection with beans for each document type (Passport, Cedule, Document, SSN, etc) and set it in the request to be collected by options tag. My questions are: Are you creating and filling this collection in the action previous the JSP? If you have this combo in multiples JSPs, Do you copypaste the collection creation in each action previous the JSP rendering? In my case, we created a new tag that uses a tinny framework we made for managing these collections, called Providers. Providers let you define collections from diferent datasources and you use this like this: html:select property=idDocument providers:options provider=DOCUMENTS property=id labelProperty=descrip/ /html:select Here, DOCUMENTS is the name of the provider, defined like this: provider name=DOCUMENTS className=ar.com.koalas.providers.FixedProvider set-property property=keyName value=key/ set-property property=description value=value/ value key=1 value=Passport/ value key=2 value=Cedule/ value key=3 value=SSN/ /provider You can use JDBCProvider to query from a database, or RefProvider to filter other Provider. And you could add new providers types Another problem is having an id, get a description. If you have an id (for instance, idDocument) you can get the description, in a bean:write fashion: providers:write provider=DOCUMENTS property=idDocument/ This displays Document description acording to idDocument property value, so you don't need to query it before JSP display. You can create providers to display, for example, boolean values in diferent ways: (Yes/No, True/False, a checked or unchecked html:checkbox tag, 2 different gifs images, etc). providers:write provider=TRUEFALSE property=isValid/ providers:write provider=YESNO property=isValid/ providers:write provider=IMAGESBOOLEAN property=isValid/ IMAGESBOOLEAN could be: provider name=IMAGESBOOLEAN className=ar.com.koalas.providers.FixedProvider set-property property=keyName value=key/ set-property property=description value=value/ value key=true ![CDATA[ img src=/images/true.gif ]] /value value key=false ![CDATA[ img src=/images/false.gif ]] /value /provider This solution helps us a lot in filling selects, displaying ids descriptions and increases reusability. What do you think of these solution? Does it goes against MVC? We are planing to upload this tiny framework to sourceforge.net in next week. Is there anything like this anywhere? Are we reinventing the wheel? Cheers. Guillermo. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: simple question
Here are some random guesses.. Looks like it should work to me.
I use
html-el:form action=${url}
usually url is defined in a tiles def but what you're doing should work
fine..
what about
c:set var=url value=/foo.do /
to test if its some problem with the bean:define tag you could try.
%
java.lang.String url = /foo.do;
pageContext.setAttribute(url,url);
%
or perhaps your container is storing your variable as an object. so
html:form action=%= url.toString() %
Cheers Mark

Proper use of ProcessAction, ProcessResult and ResultList
Dear Struts users:
For a couple of weeks now, I've been trying to use the ProcessAction class
in Struts Scaffold, following the book Struts in Action and the example
Artimus application in which it was demonstrated. It's pretty convenient in
that it simplifies the design of my business logic classes, making them
completely reusable outside of Struts or even a web app.
I just have a number of issues with it that I haven't resolved, despite
having stepped through the source code and closely studying the Artimus app:
1. How do you display a confirmation message when, say, a record was
successfully saved? I use a ProcessResult to wrap the results, and there is
a method ProcessResult.addMessage() which seems to allow you to add a
message to it. Here is the snippet of code...
start of Java code snippet --
...
UserManager manager = getUserManager();
List users = manager.getAllUsers();
ResultList resultList = new ResultListBase(users);
result = new ProcessResultBase(resultList);
if (resultList.getSize() 0) {
result.addMessage(users.found);
result.addMessage(new Integer(resultList.getSize()));
} else {
result.addMessage(users.none.found);
}
result.setDispatch(success);
end of Java code snippet --
and here is the JSP fragment that attempts to display the message...
start of JSP fragment -
...
logic:messagesPresent
UL
html:messages id=error
LIbean:write name=error//LI
/html:messages
/UL
/logic:messagesPresent
logic:messagesPresent message=true
UL
html:messages id=message
LIbean:write name=message//LI
/html:messages
/UL
/logic:messagesPresent
...
end of JSP fragment -
This is a verbatim copy of the message.jsp in the example Artimus
application. However, when I hit the page, an exception is thrown with the
message could not find bean message...
END OF FIRST ISSUE
==
2. How do you set a transactional token? From the code in ProcessAction (at
the very end of the preProcess() method), it appears that I have to define a
forward whose name is stored in Tokens.SET_TOKEN for a token to be set.
Does this mean that I have to define a local forward for each data entry
form that I need to guard against multiple submissions?
END OF SECOND ISSUE
=
I hope I've explained the issues above clearly. I've been looking at this
for two weeks, searching through the archives for answers without much
success. I hope that with this post, someone can give me some clues as to
where to look.
Thank you very much, and a Happy New Year to all!

RE: selecting a value from drop down list
Assuming you are using Struts to process the form submission, once the user selects a value from the drop down list and submits the form to be processed, the action which you have configured to handle this form submission, will have access to the selected value via the form configured to store the posted request information.

Re: selecting a value from drop down list
You'll find the docs here http://jakarta.apache.org/struts/userGuide/struts-html.html#select You need something like the following, please don't copy and paste and then immediately post the list. html:select property=sName html:options name=myList property=sName / /html:select Judging by the vagueness of you question i guess you'll also have to read some stuff on action forms also.

Re: selecting a value from drop down list
umm.. ehhh perhaps option value= could be why you get no value (in fact i suspect thats it).. The parameter will be whatever is in the value attribute, if you leave the value attribute out then it will default to the display string presented between the option tags..

Problem with Java 1.4 and BeanUtils and maybe PropertyUtils...
Hello, I will do my best to explain what's going on and hopefully someone
can help me out. If more information is needed, please let me know.
Here is the situation. We're upgrading our servers to user java 1.4.1. We
were previously running 1.3 A few of our web pages loop through collections
and the user can modify something in the collection then save the changes.
In 1.3 everything worked fine, no problems. However, when I switched to
1.4.1 (and tried 1.4.2) we started getting this error. I've tracked it down
to this line in the PropertyUtils.java class:
---
if(descriptor instanceof IndexedPropertyDescriptor)
---
In 1.3 this was true. In 1.4 this returns false, and things go downhill
from there.
Please, any help would be terrific. Thank you.

Re: Problem with Java 1.4 and BeanUtils and maybe PropertyUtils...
I haven't had any of these sorts of problems even when moving struts
app from 1.3 to 1.4 (i generally just follow what apple provide on osx
and then just match it on linux for live servers and such like.
What i can tell you though it that I've used c:set .. in the same way
as you're using bean define and works just great.
c:set var=idWorkDay value=${day.workDay} /
I tend to keep this sort of thing out of my jsp's, but looking at the
way you seem to code jsp I think you'd really like jstl. And it
defiantly works with 1.4.
Hope this helps

Here is the situation. We're upgrading our servers to user java
1.4.1. We were previously running 1.3 A few of our web pages loop
through collections and the user can modify something in the
collection then save the changes. In 1.3 everything worked fine, no
problems. However, when I switched to 1.4.1 (and tried 1.4.2) we
started getting this error. I've tracked it down to this line in the

In 1.3 this was true. In 1.4 this returns false, and things go
downhill from there.
Please, any help would be terrific. Thank you.

Adding items to a vector of formbean in the jsp
Struters, I need help from somebody.

But if i, dinamicly with dom, create new inputs increasing the index (like in the example below) and submit the page, i get a exception of Beans.populate(), a out of ranger error. newInput = document.createElement(input); newInput.type = hidden; newInput.name = userList[2].id; newInput.id = id2; myHmtlBody.appendChild(inp); document.getElementById(id2).value = 3; newInput = document.createElement(input); newInput.type = hidden; newInput.name = userList[2].name; newInput.id = name2; myHmtlBody.appendChild(inp); document.getElementById(name2).value = peter; What i really want is that, when i submit the page, the requestprocessor add a new item in the vector and set the values of the new item with the values of the new inputs.

RE: Adding items to a vector of formbean in the jsp
Paulo, The problem is that Vectors or Arrays are not created and sized for you automatically. When your form is submitted, the populate() method attempts to set the Vector element of new element which is beyond the size of your vector. To fix this problem, you can either size the Vector with empty slots in your action before you display the form or use a LazyList (search the archives for LazyList) Regards, Richard -Original Message- From: Paulo Rezende [mailto:[EMAIL PROTECTED] Sent: Monday, January 05, 2004 10:03 AM To: Struts Users Mailing List Subject: Adding items to a vector of formbean in the jsp Struters, I need help from somebody.

Well, oddly enough, when I changed:

in my FormBean, it worked. It appears that List was the problem. Very odd.

RE: Link Tag
Struts automatically append the 'CONTEXT' for you in preparing the link url. So use it with care. I had this problem before. For example, when the tile (I'm not sure if you're using tile, but it's my case) belongs to the root context (), and you want to link to a page in another context, say 'dcsi', then you need the '/dcsi/logoff.do', But in the body tile, I suppose it's already in the dcsi context, you only need to link to '/logoff.do'.

Doubts about FacesRequestProcessor on struts-faces
Ok, I suppose this is a direct question to Craig as the maintainer ofstruts-faces:I'm studying JSF and I need to integrate a Struts application with it,so I am studying struts-faces too. My problem is that this applicationuses a custom RequestProcessor that implements the ProcessingFilterpattern and in the *KNOWN LIMITATIONS* of struts-faces it says that Ihave to subclass FacesRequestProcessor (I'm not using Tiles). Thequestion is: ¿this behaviour is planned to be stable? ¿will I have tochange the implementation later? I will also be grateful for some adviceon how to do it.Thanks in advance. -- Diego Louzán Martínez - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: struts help using logic:iterate
If you make your Item class returns an Error object, you can avoid the
errorCodeList, something like this:
public class Item {
private int id=0;
private MyError error;
/**
* @return Returns the error.
*/
public MyError getError() {
return error;
}
/**
* @param error The error to set.
*/
public void setError(MyError error) {
this.error = error;
}
/**
* @return Returns the id.
*/
public int getId() {
return id;
}
/**
* @param id The id to set.
*/
public void setId(int id) {
this.id = id;
}
/**
* @param id
*/
public Item(int id) {
super();
this.id = id;
}
}
assume that you have MyError class defined as a JavaBean with two
properties errorCode (int) and errorString (String).
in your jsp:
%
java.util.Collection itemList = new java.util.ArrayList();
hqn.Item item1 = new hqn.Item(1);
item1.setError( new hqn.MyError(1, Error Description 1) );
itemList.add( item1 );
hqn.Item item2 = new hqn.Item(2);
item2.setError( new hqn.MyError(2, Error Description 2) );
request.setAttribute(itemList, itemList );
%
Using JSTL forEach tag:
c:forEach items=${itemList} var=item
Item ID= c:out value=${item.id}/BR
Error Code: c:out value=${item.error.errorCode}/BR
Error Desc: c:out value=${item.error.errorString}/BR
/c:forEach
Using logic:iterate tag:
logic:iterate id=item name=itemList
Item Id= bean:write name=item property=id/BR
bean:define id=error name=item property=error/
Error Code: bean:write name=error property=errorCode/BR
Error Desc: bean:write name=error property=errorString/BR
/logic:iterate
I'd recommend you to use JSTL.

I have two Arraylist call itemList and errorCodeList. The itemList

errorCode which returns an error code in int (1-50). I want to
display the error description associates to that error code. How can
I pass in the error code to the errorCodeList the get the error

As of the latest nightly builds of the struts-faces library, you specify your overridden class name in the usual way (with the controller element in struts-config.xml). At some point during the development of Struts 1.2 and 2.0, we'll switch our primary approach to something like commons-chain (see this package in the Jakarta Commons Sandbox, and the source code in the contrib/struts-chain directory of the Struts source archive, to get a feel for where we're going). At that point, you will be able to configure and customize your own processing chains based on the combination of technologies that you are using, without having to explicitly subclass a monolithic RequestProcessor base class. In terms of mechanics, it's really no different than subclassing the standard RequestProcessor -- simply create a class that extends the base one, and override the methods you need to change. You'll need struts-faces.jar on your compile classpath, of course. Diego Louzán Martínez Craig - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Ok, kool. I had a similar thing that I wanted to do. I wanted to be able to
determine odd or event numbered rows in a table so I could alternate the
background colour like old fashioned printouts.
I decided to do it as custom tags. Look up your J2EE tutorials for creating
these.
http://java.sun.com/j2ee/1.4/docs/tutorial/doc/
I ended up with 4 custom tags:
counterReset - creates the counter variable in the page context set to 0.
counterIncrement - adds 1 to the variable.
counterNumber - outputs the current value.
counterEvenOrOdd - Outputs the strings Odd or Even
Each tag has 1 required parameter called var which is the name of the
variable in the page context to be used. By specifying a variable name (same
as other struts tags do) I was able to run more than one counter when
necessary. Writing these tags was simplicity itself once I got the hang of
it.
If you go this way you will find you can do all sorts of wizzo things with
them. For example:
mytags:counterReset var=counter /
c:forEach
mytags:counterIncrement var=counter /
c:if test=${counter == 10}
...
/c:if
/c:forEach
If you do this you can just add /tabletable tags inside the if statements
to achieve the break up of your data. I used the odd or event tag inside
class values on table cells so that the CSS classes Odd or Even where applied
to the cells.
