Re: Bug in order of error presentment (html:error)
There's no real difference between using one property name of your own
choosing, and using the Struts GLOBAL_ERROR property name. It's mostly just
a matter of choice. The only point I can think of is that you might want to
differentiate between things that are really global and things that are
global now but might not be later.

Thanks for the input Martin. This is helpful. Just curious, what is the
advantage in using the property name as opposed to GLOBAL_ERROR?

Subject: Re: Bug in order of error presentment (html:error)
The order of errors for a given property name will be preserved.
However,
the error lists are stored in a HashMap with the property name as the
key,
so the iteration order of those is not defined.
If you are just using html:errors/ (that is, you are not specifying
the
property attribute), then you might consider using a common property
name,
or just ActionErrors.GLOBAL_ERROR. That way, all of your errors will be
preserved in the order in which you added them.
Alternatively, you could use multiple instances of the html:errors/
tag,
one for each property, like this:
html:errors property=customerContactName/
html:errors property=customerContactPhone/
html:errors property=customerContactEmail/
Given your example, this isn't very practical for your situation, but it
might be useful in cases where multiple errors for each of a small
number
of
properties is typical.

relative urls
Hi, I've got an app that will be deployed to a number of different contexts /test /dev /staging / (root) The app contains a large amount of static content e.g. images which will always be referenced from /current_context/image some of the jsps are accessed directly and via the action servlet - sometimes with different depths for the action url e.g. /current_context/something/something_else/my_action.do /current_context/something/another_action.do /somepage.jsp this obviously rules out using relative urls for the static content but the changing contexts makes it difficult for basing the urls on root. Is the solution to precede the url to every image in every jsp with a variable containing the value of the context? Is this not a performance hit? What's the best way to do it? Is there a struts tag that does this for me? How do I achieve world peace? - oops wrong mail list. Thanks Nathan

Re: template flexability
Hi Cal, I don't know the reason why actual template implementation always turn 'true' the direct attribute when the body is used (David ?). Also, the getDirect() method of PutTag doesn't take into account the real value of 'direct', just its presence ! Maybe this behavior need to be changed. Meanwhile, if you want to try your solution, you can use the Components implementation in place of Templates. Components allow to use direct='true' with the tag body. There is also other mechanisms that could interest you.

RE: How do you use indexed properties with html:input?
Turgay,
Thanks for your help, I've tried something similar to your example, but I'm
still having some trouble. I've probably missed something obvious as I'm
new to struts JSP.
In my jsp I've got the following:
%@ page import=com.qspgroup.utc.TestGridForm errorPage=fcerror.jsp %
%@ taglib uri=/WEB-INF/utctags/fcutc.tld prefix=fcutc %
%@ taglib uri=/WEB-INF/lib/struts/struts-bean.tld prefix=struts_bean %
%@ taglib uri=/WEB-INF/lib/struts/struts-html.tld prefix=struts_html %
%@ taglib uri=/WEB-INF/lib/struts/struts-logic.tld prefix=struts_logic
%
jsp:useBean id=testGridForm class=com.qspgroup.utc.TestGridForm
scope=session /
tr
% int i=0; %
struts_logic:iterate id=element name=testGridForm property=data
td
input type=text name=%= data + i % size=10
value=struts_bean:write name=element/
/td
% i++; %
/struts_logic:iterate
/tr
My action class is as follows:
public ActionForward perform( ActionMapping mapping, ActionForm form,
HttpServletRequest request,
HttpServletResponse response ) throws
IOException, ServletException
{
if ( form == null )
{
form = new TestGridForm();
}
TestGridForm testGridForm = ( TestGridForm )form;
for ( int i = 0; i testGridForm.getData().length; i++ )
{
if ( request.getParameter( data + i ) != null )
{
testGridForm.setData( i, request.getParameter( data + i )
);
}
}
return ( mapping.findForward( success ));
}
As you can see It doesn't do a lot. My ActionForm class creates dummy data
and contains and contains get/set methods as shown below:
public class TestGridForm extends ActionForm
{
String[] data = { Rail, Fridges, Hay, 1, 2, 3, 4, 5,
6, 7, 8, 9, 10, 11, 12, 13 };
public String[] getData()
{
return data;
}
public String getData( int i )
{
return data[i];
}
public void setData( String[] data )
{
this.data = data;
}
public void setData( int i, String d )
{
data[i] = d;
}
My data gets displayed OK. On success I go to testgrid.jsp but this keeps
displaying the original data. I've checked the tomcat log files and the new
data is being sent as request parameter so I don't understand why the new
data isn't saved in my bean.
e.g. 2001-05-10 09:21:20 -Request Params:
2001-05-10 09:21:20 -data2 = 30
2001-05-10 09:21:20 -data1 = 20
TestGrid.jsp is as follows:
%@ page import=com.qspgroup.utc.DataCaptureDemo errorPage=fcerror.jsp
%
jsp:useBean id=testGridForm class=com.qspgroup.utc.TestGridForm
scope=session /
html
head
titleTest JSP/title
/head
body
h2Test JSP Page/h2
%
out.println( brdata in 1st cell is + testGridForm.getData( 0 )
);
out.println( brdata in 2st cell is + testGridForm.getData( 1 )
);
out.println( brdata in 3rd cell is + testGridForm.getData( 2 )
);
%
/body
/html
Sorry to swamp you with info, I can't seem to figure this out, although I'm
sure I've missed something obvious here.
Thanks.
Richard.

Subject: Re: How do you use indexed properties with html:input?
Hi,
I *guess* that the html: tags require a form bean (please correct me if
this is wrong) so they won't work with dynamically created page elements
like input text fields.
I did the following and it works, got the idea from Scott Walter (thanks) -
see http://www.mail-archive.com/struts-user@jakarta.apache.org/msg06972.html
There may be a better solution to this, if there is, I would like to know.
Background: dbconnection is a bean I use to keep the session's database
connection, and other objects. wpLaborEntries is a vector holding objects of
type WpLabor.
In my jsp page I create input text fields like this:
FORM METHOD=POST ACTION=UpdateWoplan.do
% int i=0; %
input type=submit value=Update_Fields
table border=1 cellpadding=0 cellspacing=0 align=center
logic:iterate name=dbconnection property=wpLaborEntries
id=wpl type=com.tz.maximo.woplan.WpLabor
tr
tdINPUT TYPE=text NAME=%=craft+i% size=5
value=bean:write name=wpl property=craftqty//td
tdINPUT TYPE=text NAME=%=lhrs+i% size=5
value=bean:write name=wpl property=laborhrs//td
tdINPUT TYPE=text NAME=%=w1+i% size=5
value=bean:write name=wpl property=wpl1//td
tdINPUT TYPE=text NAME=%=w2+i% size=5
value=bean:write name=wpl property=wpl2//td
/tr
% i++; %
/logic:iterate
/table
/FORM
So, the key point is, giving a consistent name for each input text field.
And, in my action class, I get the values like this:
public ActionForward perform(ActionMapping
RE: Posting Collections
Many thanks Niall, that clears things up for me. Do you know if there is a
reason why this is the behaviour for checkboxes? Is this just with
checkboxes or other tags as well?
I don't really like the idea of modifying the struts code - the whole point
of deciding to use it is for code reuse - I don't want to start hacking
around with the code every time a new version comes out.
Do you have an opinion on using Struts? I've been using it for a couple of
weeks now and have been struggling because of basic lack of information. I
get most of my training from this news group! I'm wondering whether I
should just jack it in and use something else.

Subject: RE: Posting Collections

The problem is the CheckBox tag currently sets the HTML name attribute to
the property, so your JSP will produced something like this:
input type=checkbox name=delete
So all the checkbox fields will have the same name.
In order for Struts to populate your Retailer bean with the delete values
you need the generated HTML to look like this:
input type=checkbox name=retailer[0].delete
input type=checkbox name=retailer[1].delete etc etc.
Struts would then use getRetailer(0).setDelete(boolean) to set the delete
attributes correctly.
Unfortunately there is no easy solution - many people resort to scriptlets
to generate the name properly and there are quite a few messages in the
archive about this.
I created my own versions of Struts tags and changed them to generate the
name correctly - I like that much better - no java in the view.

Subject: Posting Collections
Briefly, this is what I am trying to achieve:
- Retrieve a list of items from a database
- Display each item with a corresponding checkbox
- Display a Delete button - which when pressed deletes all
checked items.
Unfortunately, although I have managed to display the items correctly
and
set the checkbox value using boolean values, when I do the form
submit - my
ActionForm properties do not get filled in.
This is the code I have:
My ActionForm looks like this:
public class RetailerForm extends ActionForm
{
protected Vector retailer;
/*
* On construction, fill the form with all the retailers
*/
public RetailerForm() throws SQLException
{
//here i have some code to generate my vector
//which is comprised of Retailer beans.
}
public Retailer getRetailer( int index )
{
return (Retailer)retailer.elementAt( index );
}
public Vector getRetailer()
{
return retailer;
}
public void setRetailer( Vector value )
{
retailer = value;
}
}
My Retailer bean has get and set elements for properties called
delete
and name.
My struts code looks like this (obviously within html:form tags):
logic:iterate id=retailer name=retailerForm property=retailer
tr
tdhtml:checkbox name=retailer property=delete//td
tdbean:write name=retailer property=name//td
/tr
/logic:iterate
And this all works ok for displaying the data. However, when I do the
submit my delete property for each bean is not set and I have added
debugging code to the set method and this is not called by struts. I
don't get error messages - it just doesn't happen.
I know other people have had this problem, but I am struggling to find a
solution.
Can anyone help me? Is there a better way of achieving what I am
trying to
achieve? If I am doing the correct thing, what's the reason it's not
working.
All help appreciated.

Getting hold of the session
Hi,
One of my getter methods (called by struts) needs to get hold of an object
in the Session so that it can populate the values of a drop down box based
upon a call to the customer object which is stored in the session.
Unfortunatley struts does not pass my method the request or the session
object and neither does it pass either of these to the form constructor so
I can't store a local reference to it in the form.
This problem must have been encountered and solved by others already, does
anyone have any suggestions?

Allen,
You can set the transactional token in your edit Action class with
saveToken(request). Then you can test the token in
the submit action.
I suggest you have a look at the classes EditRegistration and
SaveRegistration in the example application.

I have added scope=session to the logic:iterate tag e.g.
struts_logic:iterate id=element name=testGridForm property=data
scope=session
On the page where I display the results I also have:
jsp:useBean id=testGridForm class=com.qspgroup.utc.TestGridForm

I expected all the above to refer to the session scoped bean testGridForm,

Subject: RE: How do you use indexed properties with html:input?
Turgay,
Thanks for your help, I've tried something similar to your example, but I'm
still having some trouble. I've probably missed something obvious as I'm
new to struts JSP.
In my jsp I've got the following:
%@ page import=com.qspgroup.utc.TestGridForm errorPage=fcerror.jsp %
%@ taglib uri=/WEB-INF/utctags/fcutc.tld prefix=fcutc %
%@ taglib uri=/WEB-INF/lib/struts/struts-bean.tld prefix=struts_bean %
%@ taglib uri=/WEB-INF/lib/struts/struts-html.tld prefix=struts_html %
%@ taglib uri=/WEB-INF/lib/struts/struts-logic.tld prefix=struts_logic
%
jsp:useBean id=testGridForm class=com.qspgroup.utc.TestGridForm
scope=session /
tr
% int i=0; %
struts_logic:iterate id=element name=testGridForm property=data
td
input type=text name=%= data + i % size=10
value=struts_bean:write name=element/
/td
% i++; %
/struts_logic:iterate
/tr
My action class is as follows:
public ActionForward perform( ActionMapping mapping, ActionForm form,
HttpServletRequest request,
HttpServletResponse response ) throws
IOException, ServletException
{
if ( form == null )
{
form = new TestGridForm();
}
TestGridForm testGridForm = ( TestGridForm )form;
for ( int i = 0; i testGridForm.getData().length; i++ )
{
if ( request.getParameter( data + i ) != null )
{
testGridForm.setData( i, request.getParameter( data + i )
);
}
}
return ( mapping.findForward( success ));
}
As you can see It doesn't do a lot. My ActionForm class creates dummy data
and contains and contains get/set methods as shown below:
public class TestGridForm extends ActionForm
{
String[] data = { Rail, Fridges, Hay, 1, 2, 3, 4, 5,
6, 7, 8, 9, 10, 11, 12, 13 };
public String[] getData()
{
return data;
}
public String getData( int i )
{
return data[i];
}
public void setData( String[] data )
{
this.data = data;
}
public void setData( int i, String d )
{
data[i] = d;
}
My data gets displayed OK. On success I go to testgrid.jsp but this keeps
displaying the original data. I've checked the tomcat log files and the new
data is being sent as request parameter so I don't understand why the new
data isn't saved in my bean.
e.g. 2001-05-10 09:21:20 -Request Params:
2001-05-10 09:21:20 -data2 = 30
2001-05-10 09:21:20 -data1 = 20
TestGrid.jsp is as follows:
%@ page import=com.qspgroup.utc.DataCaptureDemo errorPage=fcerror.jsp
%
jsp:useBean id=testGridForm class=com.qspgroup.utc.TestGridForm
scope=session /
html
head
titleTest JSP/title
/head
body
h2Test JSP Page/h2
%
out.println( brdata in 1st cell is + testGridForm.getData( 0 )
);
out.println( brdata in 2st cell is + testGridForm.getData( 1 )
);
out.println( brdata in 3rd cell is + testGridForm.getData( 2 )
);
%
/body
/html
Sorry to swamp you with info, I can't seem to figure this out, although I'm
sure I've missed something obvious here.
Thanks.
Richard.

Hi,
One of my getter methods (called by struts) needs to get hold of an object
in the Session so that it can populate the values of a drop down box based
upon a call to the customer object which is stored in the session.
Unfortunatley struts does not pass my method the request or the session
object and neither does it pass either of these to the form constructor so
I can't store a local reference to it in the form.
This problem must have been encountered and solved by others already, does
anyone have any suggestions?

String saved = (String)

RE: Session management with Struts
In that case i would advise you to maintain a Hashmap/Hashtable of form objects wrapped inside an Global Action form (session scope). Every time a user opens a new browser window, i am sure that a unique id can be generated for the new window ( i have seen a posting on this list a month back where somebody has explained that using javascript we can generate a unique id for every new web browser that was opened by the user). Store this id in a hidden name=value pair. Check the mail archives as to how to do this. Over-ride your ActionServlet service() method where you initially check the id of the browser window. (btw the form objects wrapped inside the GlobalActionForm object will be mapped to these id's.) . When the corresponding form object is found, then you populate the data in that form object. If no form object is found, then create a new form object and populate the data in that form object (using reflection). Struts has libraries to do this. This is a complicated way of doing it, but the best that could pop out of my brain this time...(morning blues. I could use some caffeine). cheers, Amar.. -Original Message- From: TJM Todd McGregor [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 09, 2001 5:44 PM To: '[EMAIL PROTECTED]' Subject: RE: Session management with Struts But that's exactly my problem.

RE: Basic Design Question...
The problem with multiple servlets. 1) Security is a pain when you should check in each and every servlet. In a single servlet you have one point of entry/ on point of exit. So security can be implemented quite efficiently. 2) Ease of maintenance. For example when you are porting across multiple servlet engines then maintenance is a problem. 3) Changes in how you handle your requests can be easily applied (since you handle them at nly one servlet). I am sure that there are tons of other reasons out there. However i think the above points are valid enough for me to stick to a single servlet instead of multiple ones... I worked on projects before (when the servlet api has come out) where i used multilpe servlets. Trust me, it is not a pleasant thought for me now when i think of those times, cause i ran into all those problems i had mentioned above. cheers, Amar.. -Original Message- From: Prakash Dominic [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 09, 2001 6:52 PM To: [EMAIL PROTECTED]; '[EMAIL PROTECTED]'@jaydemail.com; [EMAIL PROTECTED] Subject: RE: Basic Design Question...

RE: How do you use indexed properties with html:input?
Richard,
I put my bean in session scope when I create it in an action class:
OracleConnBean dbconn=null;
dbconn = (OracleConnBean)session.getAttribute(dbconnection);
if(dbconn == null) {
dbconn = new OracleConnBean();
session.setAttribute(dbconnection, dbconn);
}
Then, I can access the object from my jsp pages without using jsp:useBean.
I am not exactly sure because I am not very much experienced with
jsp/servlets, but this may be the reason for those 3 beans created. By the
way, how did you find that out? How do you debug? (This may be a more
general question as what is the best way to debug jsp/servlets? I don't
debug yet, but I want to. I am using Forte CE. I heard about debugging in
Tomcat using IBM VAJ, do I need to get that?)
When you don't use jsp:useBean, you better use the type attribute in your
iterate tag, to get the correct object type:
struts_logic:iterate id=element name=testGridForm property=data
type=type_of_your_data_element

Maybe
use need to use the jsp:useBean name="tabTest"

your jsp page. Give it a shot and let me know...

Re: document.testbean.submit is not a function
Bart,
I did find the source of this problem. If the submit button is named the
default property value of submit, Javascript assumes that the button is being
referred to, not the function when the form.submit() request is processed. By
using the property tag and a value other than submit, JavaScript is no longer
confused.

Subject: document.testbean.submit is not a function
Date: Wed, 09 May 2001 08:27:24 -0600
I've modified the html-select.jsp example to include the script:
SCRIPT
function cbChanged() { document.testbean.cbSearch.value = Search
document.testbean.submit()
}
/SCRIPT
I'm setting a hidden property so that I can fill a select elements options
in
the Action peroform method based on the selection made in another select
element. When I do this I get the JSP error: document.testbean.submit is
not a
function.
Isn't that a JavaScript error?
I got this error when I tried to submit a form using a link. I removed all
the regular submitbuttons and then it worked.
I get the same result if I try to send reset rather than submit. Is
Javascript
unaware of the submit button property? Is there a better way to approach
this?

AW: Getting hold of the session
Hi Andrew,
why don?t you populate your beans before you call your jsp (where i asume
your getter methods are being called). i.e. let your ActionClass gather all
customer information, prepare your bean, drop it in the session and access
it in your jsp.
If you want to directly populate your ActionForm check the mailing list. The
topic was discussed a few times.

Betreff: Getting hold of the session
Hi,
One of my getter methods (called by struts) needs to get hold of an object
in the Session so that it can populate the values of a drop down box based
upon a call to the customer object which is stored in the session.
Unfortunatley struts does not pass my method the request or the session
object and neither does it pass either of these to the form constructor so
I can't store a local reference to it in the form.
This problem must have been encountered and solved by others already, does
anyone have any suggestions?

Allen,
You can set the transactional token in your edit Action class with
saveToken(request). Then you can test the token in
the submit action.
I suggest you have a look at the classes EditRegistration and
SaveRegistration in the example application.

I would like to use the transaction token logic in the Action class.
However I am not able to figure out how to place the Transactional Token
in
the JSP so it can be validated against when isTokenValid() is called
within
my Action class. I looked at the Struts source code to find:
protected boolean isTokenValid(HttpServletRequest request) {
// Retrieve the saved transaction token from our session
HttpSession session = request.getSession(false);
if (session == null)
return (false);
String saved = (String)
session.getAttribute(TRANSACTION_TOKEN_KEY);
if (saved == null)
return (false);
// Retrieve the transaction token included in this request
String token = (String)
request.getParameter(Constants.TOKEN_KEY);
if (token == null)
return (false);
// Do the values match?
return (saved.equals(token));
}
The Contants class is org.apache.struts.taglib.html.Constants.

RE: Basic Design Question...
I think some people are missing the point you're trying to make, so I I'm going to take a stab at it. Yes, the Servlet and Action APIs are very similar, but a Servlet and an Action really have are two different entities. A Servlet's set of interfaces covers what is required of an Action and much more. You usually want to have a set of interfaces that describes succinctly what an entity is suppose to do. An Action performs a particular web action. This does not necessarily describe a servlet. You would risk bringing in a lot of confusion into the whole framework. Can an Action be setup as a standalone Servlet? To what extent should an Action adhere to the Servlet spec? What would the init() and destroy() methods do?

RE: How do you use indexed properties with html:input?
Turgay,
I've just tried that but get the following exception:
javax.servlet.jsp.JspException: Cannot find bean contributorEditForm in

I've removed all useBean tags from my jsp and have added the following in my
action class:
ContributorEditForm contributorEditForm =
(ContributorEditForm)session.getAttribute( contributorEditForm );
if ( contributorEditForm == null )
{
contributorEditForm = new ContributorEditForm();
session.setAttribute(contributorEditForm, contributorEditForm );
}
My JSP contains code like: struts_logic:iterate id=rows
name=contributorEditForm property=data scope=session
Have I done something wrong?
As for debugging, I haven't really been able to so far, I've just been
putting System.out's in my Action class. I'm about to install JBuilder

debugging, so I'll let you know if it's any good.

Richard,
I put my bean in session scope when I create it in an action class:
OracleConnBean dbconn=null;
dbconn = (OracleConnBean)session.getAttribute(dbconnection);
if(dbconn == null) {
dbconn = new OracleConnBean();
session.setAttribute(dbconnection, dbconn);
}
Then, I can access the object from my jsp pages without using jsp:useBean.
I am not exactly sure because I am not very much experienced with
jsp/servlets, but this may be the reason for those 3 beans created. By the
way, how did you find that out? How do you debug? (This may be a more
general question as what is the best way to debug jsp/servlets? I don't
debug yet, but I want to. I am using Forte CE. I heard about debugging in
Tomcat using IBM VAJ, do I need to get that?)
When you don't use jsp:useBean, you better use the type attribute in your
iterate tag, to get the correct object type:
struts_logic:iterate id=element name=testGridForm property=data
type=type_of_your_data_element

Hi,
I made the following changes in my Action class and got my save to work.
HttpSession session = request.getSession();
TestGridForm testGridForm = (TestGridForm)session.getAttribute(
testGridForm );
However, while trying to debug my problem I found I get 3 ActionForm Beans
created when I only expected 1.
In my jsp I have the following:
jsp:useBean id=testGridForm class=com.qspgroup.utc.TestGridForm
scope=session /
I have added scope=session to the logic:iterate tag e.g.
struts_logic:iterate id=element name=testGridForm property=data
scope=session
On the page where I display the results I also have:
jsp:useBean id=testGridForm class=com.qspgroup.utc.TestGridForm
scope=session /
I expected all the above to refer to the session scoped bean testGridForm,
so why are 3 beans created?

RE: Logic iterate problems
i'll send u some code that u can adapt for Vectors that we used quite
effectively with Arraylists, try it out...
we used like a wrapper class to put our collection object in as follows:
-
package com.didata.itax.payment.web.data;
import java.util.ArrayList;
/**

public class EFilerList {
private ArrayList list = null;
private int size = 0;
public int getSize(){

}
public EFilerList() {
list = new ArrayList();
}
public EFilerList(ArrayList newList) {
list = newList;
}
public void addEFiler(EFiler efiler){
list.add(efiler);
}
public void removeEFiler(int eFilerID){
list.remove(eFilerID);
list.trimToSize();
}
public EFiler[] getEfilers(){//the iterate tags property=efilers will
call this method!!
EFiler[] eFilers = new EFiler[list.size()];
eFilers = (EFiler[])list.toArray(eFilers);
return eFilers;
}
public EFiler getEfiler(int eFilerID){
EFiler eFiler = new EFiler();
eFiler = (EFiler)list.get(eFilerID);
return eFiler;
}
}
in your actionform or wherever u build the vector, use the above class to
wrap your Vector, then, u push this list class above as your session object.
This class is juts a wrapper, so we can access the ArrayList or Vector in
our jsp. Once you've built EFilerList, put all the elements in it that u
need, add it to the session session.setAttribute...etc
the jsp for the above example looks like this
logic:iterate id=eFilerList
name=eFilerList scope=session property=efilers
tr
td align=center
bean:write name=eFilerList
property=firstName filter=true/

Design Error?
Cheers Dudley,
I have a solution but I am not happy with it (and I now also have the
additional problem that checkboxes only get sent back if they are set so I
can't tell which checkbox has been checked! - Another one to sort out).
Do you know if this is a design error. Basically, the problem is this (for
those who haven't been following the thread):
- I have a number of beans held in a Vector.
- In my ActionForm I have a two getters for this vector - one returns the
vector and one returns elements of the vector - so something like this:
public RetailerBean getRetailerBean( int index )
{
return (RetailerBean)retailers.elementAt( index );
}
and
public Vector getRetailers()
{
return retailers;
}
This works fine to populate using the following type of iterate tag:
logic:iterate id=retailer name=retailerForm property=retailers
tr
tdhtml:checkbox name=retailer property=delete//td
tdhtml:text name=retailer property=name//td
/a/td--
/tr
/logic:iterate
However, it doesn't repopulate the beans when I do a submit. This is
because the generated html is something like:
input type=checkbox name=delete
rather than:
input type=checkbox name=retailer[0].delete
input type=checkbox name=retailer[1].delete
which would allow my beans to be repopulated.
The outcome of this is that I have to create arrays for all properties of my
beans in my ActionForm and take the values from there. This seems like
bodge-heaven and not at all object-oriented.
If the form can be populated directly from the beans then surely it should
work the other way too.
Any struts developers want to comment?
Thanks for all your help.
Cheers
Tony

I think I am doing the same thing that you want to do using the
html:multibox. When the form is submitted you get an array of the ids that
are checked and then you can go delete them.
in the jsp form (where restaurant id is a key for the item being deleted):
logic:iterate id=restaurant name=favoriterestaurants
...
html:multibox property=favoriteRestaurantRemoveList
bean:write property=restaurantId name=restaurant/
/html:multibox
...
/logic:iterate
in the form class:
private Long favoriteRestaurantRemoveList[] = new Long[0];
public Long[] getFavoriteRestaurantRemoveList() {
return (this.favoriteRestaurantRemoveList);
}
public void setFavoriteRestaurantRemoveList(Long
favoriteRestaurantRemoveList[]) {
this.favoriteRestaurantRemoveList = favoriteRestaurantRemoveList;
}
I am not sure if initializing the array to new Long[0] is necessary,
probably not.

RE: Logic iterate problems
Have you tried this? It should work as long as whatever is in the Vector has
a method defined like: public String getName();
logic:iterate id=client name=tabTest
bean:write name=client property=name/
/logic:iterate
Put something like this at the top of your JSP just to make sure tabTest is
in there.
%
Object obj = session.getAttribute(tabTest);
if (obj==null)
{
System.err.println(The action wasn't called before this jsp);
}
else
{
System.err.println(tabTest is a + obj.getClass().getName());
}

Re: ActionForm.reset() not called when form tag creates bean
The problem is that my reset() method populates the form with default values (the ones I want the user to see when she first gets to the form). The workaround is to send requests like these through a no-op Action with the same form type and name. This will cause the form to be created. The Action should have validate=false in struts-config.xml. You can use the same Action class for any situation like this (since the Action itself is a no-op). I suppose I could preserve the intent of the reset() method (which I still don't fully understand) by having all of my ActionForms implement a method like populateDefaults(mapping, request) and have the action invoke this method on its form. But what I have works for now...

Checkbox Arrays

The problem is that I have only checkboxes that are checked get sent back -
so if one checkbox is checked all I get is an array of length 1. Therefore,

In the documentation it tells me to use reset() in ActionForm to initialise
the values - but this will only work with single checkboxes and not arrays.

Re: Checkbox Arrays
Im not sure how the ActionForm changes things, but without an actionform your
could do this
Each checkbox can have the same name, but a different value.
When the form is submitted, the checkboxes that have been checked are in the
request.
You can use the request.getParameterValues(checkBoxName) to retrieve a string
array of the values for the checked boxes.

RE: Checkbox Arrays
I posted this same response to your Posting Collections question yesterday.
Here it is again. If you use the html:multibox, you can get back an array of
key values instead of an array of booleans. They key values can be Longs,
Strings, whatever, as long as it uniquely identifies the row that you want
to know was checked. If you haven't used multibox, it generates an html
checkbox. The array that will be set in your form will only contain the key
values for the rows that were checked.
Here is the post from yesterday:
I think I am doing the same thing that you want to do using the
html:multibox. When the form is submitted you get an array of the ids that
are checked and then you can go delete them.
in the jsp form (where restaurant id is a key for the item being deleted):
logic:iterate id=restaurant name=favoriterestaurants
...
html:multibox property=favoriteRestaurantRemoveList
bean:write property=restaurantId name=restaurant/
/html:multibox
...
/logic:iterate
in the form class:
private Long favoriteRestaurantRemoveList[] = new Long[0];
public Long[] getFavoriteRestaurantRemoveList() {
return (this.favoriteRestaurantRemoveList);
}
public void setFavoriteRestaurantRemoveList(Long
favoriteRestaurantRemoveList[]) {
this.favoriteRestaurantRemoveList = favoriteRestaurantRemoveList;
}
I am not sure if initializing the array to new Long[0] is necessary,
probably not.

Subject: Checkbox Arrays
Can anyone help with this?
I have an array of checkboxes in my ActionForm represented by
boolean[] delete;
and I have a setter function
public void setDelete( boolean[] values )
{
delete = values;
}
The problem is that I have only checkboxes that are checked
get sent back -
so if one checkbox is checked all I get is an array of length
1. Therefore,
it is not possible for me to determine which checkbox has
been checked.
In the documentation it tells me to use reset() in ActionForm
to initialise
the values - but this will only work with single checkboxes
and not arrays.
I think I'm stuck. Is there anyway I can determine which
checkbox has been
checked - maybe I can get the value to differ for each
checkbox. Will look
in to that.
Cheers

Re: Checkbox Arrays

checkbox. My bean has an id property - so I have tried this kind of
thing:

name=retailer property=id///td
tdbean:write name=retailer property=id//td

Philosophical question(s) related to STRUTS
1) Is SunMicro going to be supporting STRUTS from a financial and/or marketing standpoint ? I only saw one tiny, tiny mention of STRUTS in the JAVAONE outline of presentations I just got in the mail. That bothers me. 2) If the answer to #1 is unknown, will JSP/Java serverside professional developers take the time to learn STRUTS and employee it in their web applications ? 3) If the answer to #1 is unknown, will corporations and consulting firms decide to committ to STRUTS in lieu of their own frameworks and methodology ?

However, as a consultant, I must be concerned about spending too much time with this if it is not going to become a popular or sanctioned approach in the webdev marketplace. Thoughts / feedback anyone ?
Re: Checkbox Arrays
the way we solved this was to create a hidden field for each checkbox that
holds the value that would be sent if the checkbox were to be checked. I
then compare the full value array sent by the hidden values with the partial
array sent by the checkboxes to see which ones were checked and which
weren't.
Both of these, of course, are inside a logic:iterate block.

Shouldn't rewrite have the same attributes as link in struts-html.tld?
Ugh... for the first time ever I had to write a pop-up using javascript :(
I'd like to do:
script type=text/javascript
function addProductToCart() {
opener.location.href = html:rewrite forward=addProductToCart
paramId=productId paramName=productId/
window.close()
}
/script
...in place of using a form so that pop-up disappears and the parent window
submits the action.
However struts-html.tld does not declare paramId and paramName attributes for
the rewrite tag as it does for the link tag. Seeing as the RewriteTag tag is
a subclass of LinkTag, and indeed calls RequestUtils.computeParameters and
RequestUtils.computeURL with all the usual LinkTag parameters (paramId,
paramName, paramProperty, etc.), copying the link attributes to rewrite in
struts-html.tld works exactly how I'd like it to.
Is there any reason why the rewrite tag be the same as link tag?
I searched bugzilla and mail-archive.com for rewrite and have not found
anything on this matter. Should I file a bug?

If you are using just Struts, then you have only one servlet, the

If you are using struts in conjunction with some other servlets, then in
your action class do this...
public class XYZAction extends Action

public ActionForward perform(mapping, form, request, response)

request.setAttribute(form, form) ;

RE: Posting Collections
This issue applies to all form field tags, not just checkboxes.
Modifying struts tags is currently a pain, but I just subimitted a bugzilla
enhancement to re-factor the tags so that they are more granualar and make
it easier to override descrete bits such as generating the name attribute.
In principle the enhacement has been accepted and I hope to submit a patch
in the next few days. If it is accepted I will have a set of custom versions
of these tags for this behviour very soon and you won't have to start
hacking around with the code every time a new version comes out and anyone
will be welcome to them.
Addtionally this issue is all on the ToDo list for 1.1 and I'm sure it

I think struts is excellent, and I love open source because you can always
look inside to see what they've done. Of course it doesn't do everything yet
;-) but I can't see it getting anything but better. We have done quite a bit
of work customizing the ActionServlet and the way its been built is
excellent, making it really easy to add addtional behaviour (hopefully)
without having to hack around every time a new version comes out.

Many thanks Niall, that clears things up for me. Do you know if
there is a
reason why this is the behaviour for checkboxes? Is this just with
checkboxes or other tags as well?
I don't really like the idea of modifying the struts code - the
whole point
of deciding to use it is for code reuse - I don't want to start hacking
around with the code every time a new version comes out.
Do you have an opinion on using Struts? I've been using it for a
couple of
weeks now and have been struggling because of basic lack of
information. I
get most of my training from this news group! I'm wondering whether I
should just jack it in and use something else.

The problem is the CheckBox tag currently sets the HTML name attribute to
the property, so your JSP will produced something like this:
input type=checkbox name=delete
So all the checkbox fields will have the same name.
In order for Struts to populate your Retailer bean with the delete values
you need the generated HTML to look like this:
input type=checkbox name=retailer[0].delete
input type=checkbox name=retailer[1].delete etc etc.
Struts would then use getRetailer(0).setDelete(boolean) to set the delete
attributes correctly.
Unfortunately there is no easy solution - many people resort to
scriptlets
to generate the name properly and there are quite a few messages in the
archive about this.
I created my own versions of Struts tags and changed them to generate the
name correctly - I like that much better - no java in the view.

Briefly, this is what I am trying to achieve:
- Retrieve a list of items from a database
- Display each item with a corresponding checkbox
- Display a Delete button - which when pressed deletes all
checked items.
Unfortunately, although I have managed to display the items correctly
and
set the checkbox value using boolean values, when I do the form
submit - my
ActionForm properties do not get filled in.
This is the code I have:
My ActionForm looks like this:
public class RetailerForm extends ActionForm
{
protected Vector retailer;
/*
* On construction, fill the form with all the retailers
*/
public RetailerForm() throws SQLException
{
//here i have some code to generate my vector
//which is comprised of Retailer beans.
}
public Retailer getRetailer( int index )
{
return (Retailer)retailer.elementAt( index );
}
public Vector getRetailer()
{
return retailer;
}
public void setRetailer( Vector value )
{
retailer = value;
}
}
My Retailer bean has get and set elements for properties called
delete
and name.
My struts code looks like this (obviously within html:form tags):
logic:iterate id=retailer name=retailerForm property=retailer
tr
tdhtml:checkbox name=retailer property=delete//td
tdbean:write name=retailer property=name//td

And this all works ok for displaying the data. However, when I do the
submit my delete property for each bean is not set and I have added

Re: Checkbox Arrays
I don't know if this is the right thread. But I just got multibox working
in my app (including preservation of checkbox entries between forwards).
Let me share with you what I have to see if this helps:
in Jsp: (cleanSolutionAreaTypes in an Application-scoped Vector)
tr
td align=left
Solutions Area*
/td
td align=left
logic:iterate id=solutionAreaType name=cleanSolutionAreaTypes
html:multibox property=solutionAreaTypes
bean:write name=solutionAreaType property=id/
/html:multibox
bean:write name=solutionAreaType property=name/br
/logic:iterate
/td
/tr
in Form:
protected String[] solutionAreaTypes = new String[0];
public String[] getSolutionAreaTypes()
{
return solutionAreaTypes;
}
public void setSolutionAreaTypes(String[] solutionAreaTypes)
{
this.solutionAreaTypes = solutionAreaTypes;
}
What was causing me some exceptions was this. I originally used another
application-scoped vector called solutionAreaTypes for other purposes
(like drop-down lists). That Vector contains an entry that has a null ID
value (eg. name = --specify-- value=). This was causing Struts to throw
a non-intuitive exception. I then created another Vector without this entry
in it and everything seems to work fine now. Of course I've only gotten it
to work about 15 minutes ago so I'll let you know later if it really works
;-)

When the form is submitted, the checkboxes that have been checked are

You can use the request.getParameterValues(checkBoxName) to retrieve

Nope the thread after invoking perform() will then decide what to do

An other way to do it is already pointed out by other people. In your

Re: FW: Design Error? Bean repopulation...
I had this problem, and worked out a solution that seemed workable.
The main thing to remember with the html:xxx/ tags is the
the name part should always be the name of the form bean, and
the property be relative to that, otherwise the BeanUtils won't
be able to repopulate the form.
I tend to store my collections in SortedMap's and use the
primary key of the database table as the index into the
SortedMap (This means, each bean has a getId() which is an integer,
and the Bean has the comparable interface to sort them). Then when
I do the iterate, I iterate over the keys of the map and return just
the Map.Entry values. Then when I do the html:xxx/ I have
something like (this if from memory, based on your code, it might
take a few hacks to get right, I think you'll need a useBean for
the retailerForm, can remember)
logic:iterate id=entry collection=%=
retailerForm.getRetailers().getEntries().iterator() %
html:text name=retailerForm property=%= retailerBean[\ +
((Map.Entry) entry).getKey()) + \] %/
%!-- or, if the bean identity id id, and so we use getId)( --%
html:text name=retailerForm property=%= retailerBean[\ +
((RetailerBean) ((Map.Entry) entry).getValue())).getId() + \] %/
/logic:iterate
I use this method all the time, it works great.
Here's another message with a copy of the code I use
http://www.mail-archive.com/struts-user%40jakarta.apache.org/msg07627.html
- I have a number of beans held in a Vector.
- In my ActionForm I have a two getters for this vector - one returns the
vector and one returns elements of the vector - so something like this:
public RetailerBean getRetailerBean( int index )
{
return (RetailerBean)retailers.elementAt( index );
}
and
public Vector getRetailers()
{
return retailers;
}
This works fine to populate using the following type of iterate tag:
logic:iterate id=retailer name=retailerForm property=retailers
tr
tdhtml:checkbox name=retailer property=delete//td
tdhtml:text name=retailer property=name//td
/a/td--
/tr
/logic:iterate
However, it doesn't repopulate the beans when I do a submit. This is
because the generated html is something like:
input type=checkbox name=delete
rather than:
input type=checkbox name=retailer[0].delete
input type=checkbox name=retailer[1].delete
which would allow my beans to be repopulated.
The outcome of this is that I have to create arrays for all properties of my
beans in my ActionForm and take the values from there. This seems like
bodge-heaven and not at all object-oriented.
If the form can be populated directly from the beans then surely it should
work the other way too.
Initialization of Request-Scoped Objects
When myAction.do is called, I have a chance within reset() to initialize my request-scoped objects. However, if myAction.jsp is called instead then I can't seem to find a way to get initialized. Are there any methods called in my Action class when the .jsp file is invoked instead of the .do file?
Re: Initialization of Request-Scoped Objects
No. What I do (antd I think it this is from the example app as well, maybe subscription.jsp) is to put at the beginning of the .jsp file (this is from memory, don't have the code handy) logic:notPresent name=yourFormBean logic:forward forward=editFormCode/ /logic:notPresent Where editFormCode is set up as a forward in the struct-config.xml file. This way, if the form bean has not been set up, it forwards the code through the form bean. This technique is useful for things like checking a user bean has been set in the session as well.

I started by placing the *.war files in webapps directory. After copying xalan xerces jar files into the lib directory almost all of the example apps worked. My next step was to setup the struts-blank then modify it to get a feel for how strut works. When I try to add logon to the blank app I get the message below. What does this mean? Do I need to post more info?

RE: How do you use indexed properties with html:input?
Richard,
Make sure that your bean is put in the session scope *before* the jsp page
is called. (In some earlier Action class)
And, please do not take me wrong: you can of course use useBean tags, but
what I understand is, you should avoid this when possible (when you can do
it with Struts tags).
Turgay.

I've just tried that but get the following exception:
javax.servlet.jsp.JspException: Cannot find bean contributorEditForm in
scope session
I've removed all useBean tags from my jsp and have added the following in my
action class:
ContributorEditForm contributorEditForm =
(ContributorEditForm)session.getAttribute( contributorEditForm );
if ( contributorEditForm == null )
{
contributorEditForm = new ContributorEditForm();
session.setAttribute(contributorEditForm, contributorEditForm );
}
My JSP contains code like: struts_logic:iterate id=rows
name=contributorEditForm property=data scope=session
Have I done something wrong?
