Array of Beans used in an ActionForm
Hello!
Is is possible to deal with an Array of Beans in an AtionForm?
It should look like this:
public class TestForm extends ActionForm {
private DataBean[] dataBeans = DataBean[size_of_array];
getter and setter methods
}
public class DataBean {
private String name=;
private int id = 0;
getter and setter methods
}
Searching the list I have found the following important facts:
- It is important to have an default construktor in the ActionForm, which
creates an instance of the Array.
Have somebody some code example to help me?
Kind regards,
Arne

Re: Array of Beans used in an ActionForm
If you want to use an array for a property that your JSP uses as indexed (i.e.
property=data(n)) you will have to
define indexed getters and setters :
public void setData(index i, String value) {
this.data[i] = value;
}
public String getData(index i) {
return this.data[i];
}
Struts will not create an instace of the array for you when it creates or populates
the formBean. Your form-bean has to
create the array in the good size before population occurs.

Re: Problem forwarding from a Tile or Template.
Hi, The provided code should work with Tiles if you have set the TilesRequestProcessor. The problem is that the jsp spec forbid the use of forward once the response is committed. But the jsp spec also said that a response is committed when you do an insert(). Tiles, and Templates, use include(). Struts action forward tag use forward(). So there is a problem. The TilesRequestProcessor takes care of this problem, and use include() instead of forward() when you use a forward ... in a struts action.

Re: Using a Tile Definition from within a Servlet ?
Yes, it is possible. There is no simple API to do that, but take a look at the TilesRequestProcessor.processTilesDefinition(...) method to know how it is done by the struts servlet. What you should do is: * retrieve the definition from the factory * create the new tile context from thedefinition * save the current tile context * store the new tile context in the jsp context * include the new tile * restore the current context Hope this help, Cedric Trevor Nightingale wrote: Is it possible to forward to a tiles definition with a servlet ?

Re: HELP: Dispaly Date in a JSP that used Tiles
You don't need to create an ActionForm, since the form is never going to
be submitted, and you don't need to be able to access the form
information outside of the current page. So just use plain html tags
instead of the struts-html tags.

First, thanks a lot for your help.
I think indeed that this manner of making is better
but I have a problem to set up it.
Because I must define a tag form.
form name=myForm
input type=text name=dateControl size=30
/form
As I explained in my previous message I use Tiles all the
pages are composed of several modules header, menu, body and footer.
It is in the header module that I want to display the date,
for the moment the header.jsp page is the following:
%@ taglib uri=/WEB-INF/tld/struts-bean.tld prefix=bean %
%@ taglib uri=/WEB-INF/tld/struts-html.tld prefix=html %
form name=MyForm
table border=0 width=100% cellspacing=0 cellpadding=0

td width=40 align=left
bean:message key=label.project.version/
/td
td width=80% align=right
html:text name=MyForm property=dateControl size=30/
noscriptbean:message key=label.javascript.required//noscript
/td
/tr
/table
/form
When I run the application I have an error no instance of MyForm
has been created.
I thus defined a DynaValidatorForm in struts-config.xml,and use the Struts
tag
html:form name=MyForm. But when I compile the application I have the
following
message action is mandatory for tag form.
But I don't want to associate an action to this page.
How can I do ?

Subject: RE: HELP: Dispaly Date in a JSP that used Tiles
I think your problem has nothing to do with tiles or jsp. You just need
to write the output to a control instead of trying to write to the page.
If the browser were to allow your code to work as you have written it
you would actually get a list of times.
The following code should work - it renders to a named textBox.
BEGINNING OF CODE SAMPLE --
script type=text/javascript
function aff_heure() {
var d=new Date()
var weekdays=new
Array(Sunday,Monday,Tuesday,Wednesday,Thursday,Friday,Saturday
)
var monthname=new
Array(Jan,Feb,Mar,Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,Dec
)
var weekday=weekdays[d.getDay()]
var date = d.getDate()
var month = monthname[d.getMonth()]
var year = d.getFullYear()
var hour = d.getHours()
var minute = d.getMinutes()
var second = d.getSeconds()
var time = new String(weekday + + date
+ . + month + + year
+ , + hour + : + minute
+ : + second)
document.myForm.dateControl.value=time;
setTimeout(aff_heure(),100);
}
/script
form name=myForm
input type=text name=dateControl size=30
/form
END OF CODE SAMPLE --
Hope this helps,
Gareth
PS. You can also render to put your answer in other html objects such
as spans and divs but if you're trying to make it work on as many
browsers as possible that might be a bit of a headache.
PPS. Why not use d.toGMTString() or d.toLocaleString() instead of
trying to format the string yourself?

how to add a new record to a table

I have this list displayed on a jsp page with a table and I would like the last row of the table to be editable.

You don't need to create an ActionForm, since the form is never going to
be submitted, and you don't need to be able to access the form
information outside of the current page. So just use plain html tags
instead of the struts-html tags.

First, thanks a lot for your help.
I think indeed that this manner of making is better
but I have a problem to set up it.
Because I must define a tag form.
form name=myForm
input type=text name=dateControl size=30
/form
As I explained in my previous message I use Tiles all the
pages are composed of several modules header, menu, body and footer.
It is in the header module that I want to display the date,
for the moment the header.jsp page is the following:
%@ taglib uri=/WEB-INF/tld/struts-bean.tld prefix=bean %
%@ taglib uri=/WEB-INF/tld/struts-html.tld prefix=html %
form name=MyForm
table border=0 width=100% cellspacing=0 cellpadding=0
tr
td width=40 align=left
bean:message key=label.project.version/
/td
td width=80% align=right
html:text name=MyForm property=dateControl size=30/
noscriptbean:message key=label.javascript.required//noscript
/td
/tr
/table
/form
When I run the application I have an error no instance of MyForm
has been created.
I thus defined a DynaValidatorForm in struts-config.xml,and use the Struts
tag
html:form name=MyForm. But when I compile the application I have the
following
message action is mandatory for tag form.
But I don't want to associate an action to this page.
How can I do ?
Thanks a lot in advance

Subject: RE: HELP: Dispaly Date in a JSP that used Tiles
I think your problem has nothing to do with tiles or jsp. You just need
to write the output to a control instead of trying to write to the page.
If the browser were to allow your code to work as you have written it
you would actually get a list of times.
The following code should work - it renders to a named textBox.
BEGINNING OF CODE SAMPLE --
script type=text/javascript
function aff_heure() {
var d=new Date()
var weekdays=new
Array(Sunday,Monday,Tuesday,Wednesday,Thursday,Friday,Saturday
)
var monthname=new
Array(Jan,Feb,Mar,Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,De
c
)
var weekday=weekdays[d.getDay()]
var date = d.getDate()
var month = monthname[d.getMonth()]
var year = d.getFullYear()
var hour = d.getHours()
var minute = d.getMinutes()
var second = d.getSeconds()
var time = new String(weekday + + date
+ . + month + + year
+ , + hour + : + minute
+ : + second)
document.myForm.dateControl.value=time;
setTimeout(aff_heure(),100);
}
/script
form name=myForm
input type=text name=dateControl size=30
/form
END OF CODE SAMPLE --
Hope this helps,
Gareth
PS. You can also render to put your answer in other html objects such
as spans and divs but if you're trying to make it work on as many
browsers as possible that might be a bit of a headache.
PPS. Why not use d.toGMTString() or d.toLocaleString() instead of
trying to format the string yourself?

Subject: how to add a new record to a table
Hi,
I guess my problem is common but I couldn't find an answer on the
archive...
I have a bean that provides an indexed property (a java.util.List).
I have this list displayed on a jsp page with a table and I would like the
last row of the table to be editable.
When the user submits the form, I would like the last row (the editable
one) to be added as a new entry in the indexed property
Any advise for how to do that ?
Thanks
Thomas

RE: New to Struts
Yes. Basically you create a form in struts-config.xml. Then you reference that form in your action instead of the ActionForm you coded. The issue is keeping the JSP form and your declared DynaForm in SYNCH. But it is not that big of a deal. I do not use ActionFOrms at all in my application. I do not really need to. You can also validate against DynaForms, and there are heaps of postings in the archives to see about validation issues with DynaForms. But try them out first, and see how it goes. The source code examples in the stuts_src.tar worked very well for me. Was not too difficult to understand. -Original Message- From: Brian McSweeney [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 02, 2003 11:52 AM To: Struts Users Mailing List Subject: Re: New to Struts Ah, thanks Mick, So is the DynaForm the one which allows you not to create Forms declaratively using xml?

AW: Array of Beans used in an ActionForm
Hello Nico!
Thanks for your help. I now have got indexed getter and setters. Showing the
data in the JSP works fine, but getting the data back formn the JSP in the
UpdateAction didn't work.
Please notice: I dont't want to handle an array of Strings in the
ActionForm, I would like to hadle an array of Beans ( with own getters and
setters) in the AtionForm.
Maybee it make sence to post some code here for a better understanding of
the problem.
This ist the ActionForm used in the JSP:
public class TestForm extends ActionForm {
/**
* Log4j Category for this class
*/
protected final static Category cat =
Category.getInstance(TestForm.class.getName());
public TestForm (int size)
{
arrayForm = new DataBean[size];
}
public TestForm ()
{
if (cat.isDebugEnabled())
{
cat.debug(Konstruktor Start);
}
int size=3;
arrayForm = new DataBean[size];
for (int i = 0; i=(size-1);i++)
{
arrayForm[i]= new DataBean();
}
if (cat.isDebugEnabled())
{
cat.debug(Konstruktor Ende);
}
}
private DataBean[] arrayForm = null;
/**
* Gets the arrayForm
* @return Returns a ArrayForm[]
*/
public DataBean getArrayForm(int i) {
return arrayForm[i];
}
/**
* Sets the arrayForm
* @param arrayForm The arrayForm to set
*/
public void setArrayForm(int i, DataBean arrayForm) {
this.arrayForm[i] = arrayForm;
}
}
This is the Bean which is included in the array of the TestForm:
public class DataBean extends ActionForm {
/**
* Log4j Category for this class
*/
protected final static Category cat =
Category.getInstance(TestForm.class.getName());
/**
* Konstruktor
*/
public DataBean(String myName, int myId) {
this.setName(myName);
this.setID(myId);
}
/**
* Konstruktor
*/
public DataBean() {
this.setName();
this.setID(Integer.MIN_VALUE);
}
private String name = ;
private int ID = Integer.MIN_VALUE;
/**
* Gets the name
* @return Returns a String
*/
public String getName() {
return name;
}
/**
* Sets the name
* @param name The name to set
*/
public void setName(String name) {
this.name = name;
}
/**
* Gets the iD
* @return Returns a int
*/
public int getID() {
return ID;
}
/**
* Sets the iD
* @param iD The iD to set
*/
public void setID(int iD) {
ID = iD;
}
}
And last but not least my JSP code:
This works fine for showing the data, but not for updating:
%
for (int i=0; i=2; i++)
{
%
brinput type=text name=testForm.arrayForm[%= i%].name value=%=
testForm.getArrayForm(i).getName()%
%
}
%
I have also tried this code int eh JSP. Than I get the following error: No
getter method for property testForm.arrayForm[0].name
html:text property=testForm.arrayForm[0].name
html:text property=testForm.arrayForm[1].name
html:text property=testForm.arrayForm[2].name
Any ideas?

Arne

If you want to use an array for a property that your JSP uses
as indexed (i.e. property=data(n)) you will have to define
indexed getters and setters :
public void setData(index i, String value) {
this.data[i] = value;

Struts will not create an instace of the array for you when

I made a text search on RC1 sources for Locale : 30 classes use it, For using localized JSP without session, only this changes shoul be needed : RequestUtils.retrieveUserLocale() : use pageContext.getAttribute(locale); // all scopes instead of pageContext.getAttribute(locale, PageContext.SESSION_SCOPE); HtmlTag.currentLocale() : use pageContext.getAttribute(Globals.LOCALE_KEY); // all scopes instead of session.getAttribute(Globals.LOCALE_KEY); validator/Ressources.getLocale() use locale = (Locale) request.getAttribute(Globals.LOCALE_KEY); if (locale == null) locale = (Locale) request.getSession().getAttribute(Globals.LOCALE_KEY); instead of request.getSession().getAttribute(Globals.LOCALE_KEY); I will post a bugzilla ticket for a post 1.1 enhancement. Nico. You could probably override the processLocale() method in RequestProcessor to store it in the request scope, but Im not sure what would be involved over on the rendering side to get the tags to look for current locale there. If using locales does indeed require use of the session, than an enhancement for an option to allow this to be done using only the request is a good idea. This could be quite useful for higher throughput websites that dont need to track sessions - though it may involve a bit more effort from the garbage collector to clean up throwaway locale objects. -Original Message- From: Nicolas De Loof [mailto:[EMAIL PROTECTED] Sent: Wednesday, 2 April 2003 15:13 To: Struts Users Mailing List Subject: [RePosted] localize messages in JSP without session On logon.jsp I would like messages to be localized.

Re: Array of Beans used in an ActionForm
For your indexed properties, use arrayForm(x).name instead of arrayForm[x].name
Try to use JSP tags instead of scriptlets, your JSP will be more readeable to other
developers.

Re: Array of Beans used in an ActionForm
use : html:text property=arrayForm(0).name
html:text is use inside a html:form, so it assumes the current bean is the
html:form form-bean.
Here are general Sruts tags usage :
- name is the name of a bean in some scope. html:xx use form-bean as default and
doesn't need this attribute
- property is the name of the bean property, with indexed / dotted notation
- scope can be use to define where to search for teh bean. By default all scopes are
used to search.
- id is the name of a script variable / bean in scope that tag creates for you

Subject: AW: Array of Beans used in an ActionForm
Hello Nico!
Thanks for your help. I now have got indexed getter and
setters. Showing the data in the JSP works fine, but getting
the data back formn the JSP in the UpdateAction didn't work.
Please notice: I dont't want to handle an array of Strings in
the ActionForm, I would like to hadle an array of Beans (
with own getters and
setters) in the AtionForm.
Maybee it make sence to post some code here for a better
understanding of the problem.
This ist the ActionForm used in the JSP:
public class TestForm extends ActionForm {
/**
* Log4j Category for this class
*/
protected final static Category cat =
Category.getInstance(TestForm.class.getName());
public TestForm (int size)
{
arrayForm = new DataBean[size];
}
public TestForm ()
{
if (cat.isDebugEnabled())
{
cat.debug(Konstruktor Start);
}
int size=3;
arrayForm = new DataBean[size];
for (int i = 0; i=(size-1);i++)
{
arrayForm[i]= new DataBean();
}
if (cat.isDebugEnabled())
{
cat.debug(Konstruktor Ende);
}
}
private DataBean[] arrayForm = null;
/**
* Gets the arrayForm
* @return Returns a ArrayForm[]
*/
public DataBean getArrayForm(int i) {
return arrayForm[i];
}
/**
* Sets the arrayForm
* @param arrayForm The arrayForm to set
*/
public void setArrayForm(int i, DataBean arrayForm) {
this.arrayForm[i] = arrayForm; }
}
This is the Bean which is included in the array of the TestForm:
public class DataBean extends ActionForm {

this.setName();
this.setID(Integer.MIN_VALUE);

}
}
And last but not least my JSP code:
This works fine for showing the data, but not for updating:

{
%

Betreff: Re: Array of Beans used in an ActionForm
If you want to use an array for a property that your JSP uses as
indexed (i.e. property=data(n)) you will have to define indexed
getters and setters :
public void setData(index i, String value) {
this.data[i] = value;
}
public String getData(index i) {
return this.data[i];
}
Struts will not create an instace of the array for you when
it creates
or populates the formBean. Your form-bean has to create the

use : html:text property=arrayForm(0).name
html:text is use inside a html:form, so it assumes the
current bean is the html:form form-bean.
Here are general Sruts tags usage :
- name is the name of a bean in some scope. html:xx use
form-bean as default and doesn't need this attribute
- property is the name of the bean property, with indexed /
dotted notation
- scope can be use to define where to search for teh bean.
By default all scopes are used to search.
- id is the name of a script variable / bean in scope that

You don't need to create an ActionForm, since the form is never going to
be submitted, and you don't need to be able to access the form
information outside of the current page. So just use plain html tags
instead of the struts-html tags.

First, thanks a lot for your help.
I think indeed that this manner of making is better
but I have a problem to set up it.
Because I must define a tag form.

input type=text name=dateControl size=30
/form
As I explained in my previous message I use Tiles all the
pages are composed of several modules header, menu, body and footer.
It is in the header module that I want to display the date,
for the moment the header.jsp page is the following:
%@ taglib uri=/WEB-INF/tld/struts-bean.tld prefix=bean %
%@ taglib uri=/WEB-INF/tld/struts-html.tld prefix=html %
form name=MyForm
table border=0 width=100% cellspacing=0 cellpadding=0

td width=40 align=left

/td
td width=80% align=right
html:text name=MyForm property=dateControl size=30/
noscriptbean:message key=label.javascript.required//noscript
/td
/tr
/table
/form
When I run the application I have an error no instance of MyForm
has been created.
I thus defined a DynaValidatorForm in struts-config.xml,and use the Struts
tag
html:form name=MyForm. But when I compile the application I have the
following
message action is mandatory for tag form.
But I don't want to associate an action to this page.
How can I do ?
Thanks a lot in advance

Subject: RE: HELP: Dispaly Date in a JSP that used Tiles
I think your problem has nothing to do with tiles or jsp. You just need
to write the output to a control instead of trying to write to the page.
If the browser were to allow your code to work as you have written it
you would actually get a list of times.
The following code should work - it renders to a named textBox.
BEGINNING OF CODE SAMPLE --
script type=text/javascript
function aff_heure() {
var d=new Date()
var weekdays=new
Array(Sunday,Monday,Tuesday,Wednesday,Thursday,Friday,Saturday
)
var monthname=new
Array(Jan,Feb,Mar,Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,De
c
)
var weekday=weekdays[d.getDay()]
var date = d.getDate()
var month = monthname[d.getMonth()]
var year = d.getFullYear()
var hour = d.getHours()
var minute = d.getMinutes()
var second = d.getSeconds()
var time = new String(weekday + + date
+ . + month + + year
+ , + hour + : + minute
+ : + second)
document.myForm.dateControl.value=time;
setTimeout(aff_heure(),100);
}
/script
form name=myForm
input type=text name=dateControl size=30
/form
END OF CODE SAMPLE --
Hope this helps,
Gareth
PS. You can also render to put your answer in other html objects such
as spans and divs but if you're trying to make it work on as many
browsers as possible that might be a bit of a headache.
PPS. Why not use d.toGMTString() or d.toLocaleString() instead of
trying to format the string yourself?

tiles:insert tag inserting carriage return before /td on linux box
Our tiles work fine with Tomcat 4.1.12, struts1.1b3, jdk1.4.01 on an NT box, but as soon as we port it to a Linux box (SUSE, same 1.1b3, tomcat 4.1.24) our rendered html displays a subtle and rather nasty error, as a carriage return is inserted immediately before the /td tag, causing the well known rendering bug in tables. for example; td blah blahtiles:insert attribute=MainHeader //td will be rendered correctly as: td blah blah Main header text/td on the NT system, but as td blah blah Main header text /td on the linux server, with the carriage return causing ugly display problems. As far as we are aware, we have saved all our text files (jsp, html, tld, xml ...) in unix format without the NT double ODOA CR sequence. Any ideas???
Re: Array of Beans used in an ActionForm
OUPS , sory, I'm really confusing. You where right with arrayForm[0].name.
The problem is your TestForm has no getter for property arrayForm (it has only indexed
getter), so Struts JavaBean
property discovery doesn't find any property name arrayForm.
Add this to your form :
public DataBean[] getArrayForm() {
return arrayForm;
}
public void setArrayForm(DataBean[] arrayForm) {
this.arrayForm = arrayForm;
}
It will work (this time I tried it myself).
NB: if you doesn't use it as form-bean somewhere else, DataBean doesn't need to extend
ActionForm.
Nico.
Hello Nico!
Once more I have followed your advises. Now the code look like this:
html:text property=arrayForm(0).name
html:text property=arrayForm(1).name
html:text property=arrayForm(2).name
I get the following error message:
No getter method for property arrayForm(0).name of bean

Re: How to use Struts to show image from database (byte[])?
I worked on an app where we had cache set to false for Struts. In that context, using an Action to retrieve the images prevented any of them from being cached, which was bad for server load and site performance. We were using Struts 1.0.2, though perhaps Struts 1.1 allows you to set the cache behavior of each mapping/Action individually, which would have solved our performance issue for the most part. In light of that, we wrote a little servlet to serve the images. We also implemented getLastModified() to retrieve the last modification time of the requested image (which was also stored in the database). This worked great, because the images would be cached by the browser until they were updated in the db. I am not sure if that (last modification time) is supported in Struts 1.1 either, but it would be another nice thing to have for applications like this. As a side note, storing the images in the db was been very nice for us generally. Having all the data in the database is very convenient for deployment, since there are no filesystems to worry about and no chance that the filesystem would be out of sync with the db (where you would likely still store references to the binary data, stored as files in such a scenario). The performance was fine with the caching sorted out. We didn't do any rigorous comparisons to disk-based storage, but rather the performance just turned out to not be an issue for this project after the caching was fixed. Perhaps this already exists, but it would be very cool to have a system that stored (or simply allowed storage of) the image (or any similar binary data) in the db and then cached them to a local disk for performance. This would be a great J2EE or Struts-specific open source project for someone to make available. You'd get the convenience of db storage and the performance of disk storage. You could even provide a custom tag library to construct a tag (or URL) from the image/resource ID, set the size of image in the HTML, or perhaps adjust the src URL for direct access to the disk file for cached images. Though watch out for stale caches in that last scenario -- perhaps the mod times of the disk file versus the db blob could be checked when the tag is processed to avoid that problem. The image could even be pre-emptively written to the cache (assuming it is stale or not yet cached) when the tag is processed to always be able to write a URL to the file in the cache rather than to a servlet for processing. You might run into trouble if someone references the image from another site or something though, so that might not be that great after all. That is unless you have a 404 handler that could look it up in the cache if it is found to be missing on disk and reset the response code back to 200 and serve the image data from the db, which might be worth a try. The 404 handler idea would allow operation with a fixed maximum disk cache size, or avoid problems if you simply ran out of disk space to cache to, also. Or perhaps it would be simpler and just as fast to pass all requests for images through a servlet, since you'd be doing much the same kind of stuff that the FileServlet would be doing to serve the image anyway. Non-image specific tags would also be useful for other kinds of binary data stored in the db. This could be a great project if there isn't one out there already. -Max - Original Message - From: Nicolas De Loof [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Wednesday, April 02, 2003 12:46 AM Subject: Re: How to use Struts to show image from database (byte[])?

Re: Session Load Balancing Problem
Do you have the cluster setup to replicate the sessions? If so and it still isn't working correctly, write something that checks everything in your session to see if it is Serializable. You can use a simple JSP for the session check thing and just load it to make sure everything is serializable, or you could integrate some kind of serializability check that would log exceptions into your ActionBase or perhaps add it to your app as a Filter. You would obviously want to do this on a temporary basis just to check that everything is in order, and then remove it after you finish testing. Anything that isn't serializable won't be available in the session on the other node. -Max - Original Message - From: Noureddine Bekrar [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Wednesday, April 02, 2003 12:12 AM Subject: Session Load Balancing Problem Hello, I have a probleme when i want to use a load balancing of my struts application between 2 tomcat servers. when the load balancing begin , the second server say that the session was expired. but when I remove the html:select tag from my jsp pages , all work well.

In Exadel you can define module (we call it process) with process context and actually use it like function calls. You even can use recursion. That gives us ability to split system to modules using vertical (by functional areas) and horizontal (by architecture layer) approach. And we design system in a way where we have two horizontal layers - one (top) designed to handle page flow and all interface relater issues. And second (bottom) layer was dedicated to business functions. I feel that there is something good in such design, the only problem - Strut do not really helps here.

This difficulty is most closely related to the 'action chaining' posts I've been able to find in the mailing list archives. Specifically, I have over 400 pages mapped to various actions (our controller calls them that, and they're roughly synonymous with struts actions.) However, our controller allows specifying a list of actions to execute on a per-page, and per-page-set basis. In other words, we can assign an action like 'Ensure Session initialization has been completed/Initialize session' to every page in the site with a single mapping (assuming you've already listed all the pages.) Or you can assign it to 90% of your pages if you happen to desire. We have approximatly ten actions that happen on between 60-99% of the pages on our site. If we were to directly translate this to the struts mapping system we would end up having to re-specify those ten actions on most of those 400+ pages, creating long action chains for

Once more I have followed your advises. Now the code look like this:

I get the following error message:

Do Struts really know, that it has to call the method

use : html:text property=arrayForm(0).name
html:text is use inside a html:form, so it assumes the
current bean is the html:form form-bean.
Here are general Sruts tags usage :
- name is the name of a bean in some scope. html:xx use
form-bean as default and doesn't need this attribute
- property is the name of the bean property, with indexed /
dotted notation
- scope can be use to define where to search for teh bean.
By default all scopes are used to search.
- id is the name of a script variable / bean in scope that
tag creates for you

For your indexed properties, use arrayForm(x).name instead of
arrayForm[x].name
Try to use JSP tags instead of scriptlets, your JSP will be more
readeable to other developers.

Subject: AW: Array of Beans used in an ActionForm
Hello Nico!
Thanks for your help. I now have got indexed getter and setters.
Showing the data in the JSP works fine, but getting the data back
formn the JSP in the UpdateAction didn't work.
Please notice: I dont't want to handle an array of Strings in the
ActionForm, I would like to hadle an array of Beans ( with
own getters
and
setters) in the AtionForm.
Maybee it make sence to post some code here for a better
understanding
of the problem.
This ist the ActionForm used in the JSP:
public class TestForm extends ActionForm {
/**
* Log4j Category for this class
*/
protected final static Category cat =
Category.getInstance(TestForm.class.getName());
public TestForm (int size)
{
arrayForm = new DataBean[size];
}
public TestForm ()
{
if (cat.isDebugEnabled())
{
cat.debug(Konstruktor Start);
}
int size=3;
arrayForm = new DataBean[size];
for (int i = 0; i=(size-1);i++)
{
arrayForm[i]= new DataBean();
}
if (cat.isDebugEnabled())
{
cat.debug(Konstruktor Ende);
}
}
private DataBean[] arrayForm = null;
/**
* Gets the arrayForm
* @return Returns a ArrayForm[]
*/
public DataBean getArrayForm(int i) {
return arrayForm[i];
}
/**
* Sets the arrayForm
* @param arrayForm The arrayForm to set
*/
public void setArrayForm(int i, DataBean arrayForm) {
this.arrayForm[i] = arrayForm; }
}
This is the Bean which is included in the array of the TestForm:
public class DataBean extends ActionForm {
/**
* Log4j Category for this class
*/
protected final static Category cat =
Category.getInstance(TestForm.class.getName());
/**
* Konstruktor
*/
public DataBean(String myName, int myId) {
this.setName(myName);
this.setID(myId);
}

public DataBean() {
this.setName();
this.setID(Integer.MIN_VALUE);
}

You don't need to create an ActionForm, since the form is never going to
be submitted, and you don't need to be able to access the form
information outside of the current page. So just use plain html tags
instead of the struts-html tags.

First, thanks a lot for your help.
I think indeed that this manner of making is better
but I have a problem to set up it.
Because I must define a tag form.
form name=myForm
input type=text name=dateControl size=30
/form
As I explained in my previous message I use Tiles all the
pages are composed of several modules header, menu, body and footer.
It is in the header module that I want to display the date,
for the moment the header.jsp page is the following:
%@ taglib uri=/WEB-INF/tld/struts-bean.tld prefix=bean %
%@ taglib uri=/WEB-INF/tld/struts-html.tld prefix=html %
form name=MyForm
table border=0 width=100% cellspacing=0 cellpadding=0
tr
td width=40 align=left
bean:message key=label.project.version/
/td
td width=80% align=right
html:text name=MyForm property=dateControl size=30/
noscriptbean:message key=label.javascript.required//noscript
/td
/tr
/table
/form
When I run the application I have an error no instance of MyForm
has been created.
I thus defined a DynaValidatorForm in struts-config.xml,and use the Struts
tag
html:form name=MyForm. But when I compile the application I have the
following
message action is mandatory for tag form.
But I don't want to associate an action to this page.
How can I do ?
Thanks a lot in advance

Re: messages into struts 1.1
I've just had a similar problem, recently. The docs seem to be a bit misleading (or perhaps the docs are right and theres a bug somewhere?). html:messages doesn't seem to do any actual writing, its just a form of iterator that loops through the specified messages and puts them in a page-scope attribute. To actually display them you need to use bean:write eg. html:messages id=message bean:write name=message/ /html:messages Note you may also need to set the message paramater of the html:message tag to true if you have created your messages using the ActionMessages.GLOBAL_MESSAGE key as the tag (confusingly) defaults to using ActionErrors.GLOBAL_ERROR Hope this helps, Gareth [EMAIL PROTECTED] wrote: Hi everyone, Is anybody knows how to use messages system of struts.

If you are looking at going to college today (either because it's that time in your life, or because the job market sucks right now), I would suggest thinking about a primary major other than Comp Sci (with a Comp Sci minor to keep your hand in on all the technical stuff).

RE: Is Strut too primitive for really useful Controller function?
IMO, implementing business logic in the controller violates MVC principles. The Struts controller handles page flow by calling Actions. Your actions invoke methods on your business layer. By putting business logic in the controller you can't reuse it outside of that framework. If I were interested in writing non-reusable code I'd use Perl ;-).

I can not find original post from Thorin - but I'm 100% agree with his point. Moreover - I have real experience with system that allows me to implement what Thorin is talking about. We implements almost all business logic in controller layer, moreover - we have two sub-layer inside controller - presentation controller, which handles all page flow and input validations, and business controller - where actual business logic where implemented on high level. All this because of using our own implementation of MVC framework - Exadel. I'm not here to convince you to switch from Struts to Exadel, but I can tell you that Struts controller component is too primitive compared to Exadel. We used widely concept of module. In Exadel you can define module (we call it process) with process context and actually use it like function calls. You even can use recursion. That gives us ability to split system to modules using vertical (by functional areas) and horizontal (by architecture layer) approach. And we design system in a way where we have two horizontal layers - one (top) designed to handle page flow and all interface relater issues. And second (bottom) layer was dedicated to business functions. I feel that there is something good in such design, the only problem - Strut do not really helps here.

We had a similar problem. We solved this by putting each drop down list box

Dynamic Forms Indexed properties (was RE: [Struts FAQ] Update #3)

Struts FAQ - Update #3

Q3: What are indexed struts-html tags and how to use them?
These are great, thanks! I was just saying yesterday that indexed
properties might solve a problem I have, but looking at the example I'm not
sure if I can use them with a DynaValidatorForm.
In the example, does the programmer have to code the Person class with
phoneNo and name properties, or does that happen somehow automatically?
And how does this work:
public void getPerson(int index) { ... }
Shouldn't that return a Person object, or at the very least an Object,
rather than void?

ANN] Struts-FreeMarker-JSP taglibs integration
Folks, The first release of FreeMarker 2.2 labeled production/stable is available. FreeMarker 2.2 may be of special interest to Struts users because it is the first template engine, to our knowledge, that supports the usage of 3rd party JSP taglibs. This means that you can have the cleanness and simplicity of a template engine like FreeMarker without giving up the ability to use powerful 3rd party JSP taglibs like Cewolf or SiteMesh and so on. You have the best of both worlds! See http://freemarker.org/docs/pgui_misc_servlet.html for more details about how to configure Struts for use with FreeMarker. There is also an example of struts usage in the distro. For those who don't know it, FreeMarker is a well-known, tried-and-true tool for doing page templates in Java. In practice, it is mostly used in the web space to get data from servlets into HTML pages. Aside from the ability to use JSP taglibs, FreeMarker 2.2 introduces a host of powerful new features. Here is a not-necessarily exhaustive list: namespaces -- macro libraries can be defined in separate namespaces so that different people can work on different pieces without any possibility of naming clashes. For more details, see: http://freemarker.org/docs/dgui_misc_namespace.html fine control of whitespace -- this has been the bane of template engines and a constant subject on mailing lists. We think we've really nailed this problem now. For more details, see: http://freemarker.org/docs/dgui_misc_whitespace.html more powerful macros -- Macros can defined with default parameters, and can be invoked with optional body content. For more details, see: http://freemarker.org/docs/ref_directive_macro.html Simplified syntax -- Macros and transforms are now invoked with a common syntax, so, despite the increased power, FM 2.2 is actually substantially simpler! For more details, see: http://freemarker.org/docs/ref_directive_userDefined.html clean interoperability with jython -- Of special interest to python fans, jython objects can be used transparently from within FreeMarker templates. For more details, see: http://freemarker.org/docs/pgui_misc_jythonwrapper.html Okay, 'nuff said, I guess. If that doesn't pique your interest, I don't know what will.

Re: tiles:insert tag inserting carriage return before /td on linux box
Hi, The Tiles tags only insert the content of the specified pages. There is no extra insertion. So, your problem should come from one of your pages having this extra character. Check particularly the layout jsp ... Also, try to isolate the exact location in your pages where this extra car is inserted. Delete the cars and rewrite them on the unix system. Cedric Alix Jermyn wrote: Our tiles work fine with Tomcat 4.1.12, struts1.1b3, jdk1.4.01 on an NT box, but as soon as we port it to a Linux box (SUSE, same 1.1b3, tomcat 4.1.24) our rendered html displays a subtle and rather nasty error, as a carriage return is inserted immediately before the /td tag, causing the well known rendering bug in tables. for example; td blah blahtiles:insert attribute=MainHeader //td will be rendered correctly as: td blah blah Main header text/td on the NT system, but as td blah blah Main header text /td on the linux server, with the carriage return causing ugly display problems.

RE: Does a degree matter?
This brings up a good point... if all you get out of a degree is learning specific technology... in a fast changing world you might get left behind. If you learn how to learn technology... if you learn another way of thinking... then you just might have something. My degree is in Computer Engineering and the courses that really taught me something were the courses that taught me how to solve problems, how to learn new technologies, and how people and technology relate. The courses that taught me about technology X didn't mean a thing, because technology X isn't even around anymore... or has changed so much that what I learned isn't relevant anymore. I guess what I am saying is that it might not be a question of Does a degree matter?, but What should I be learning? and How can I challenge myself?. I don't think that my degree by itself has helped me all that much... but the things I learned while getting it were invaluable. I have worked with many people who become absolutely paralyzed by complex problems, while getting my degree I learned to deal with these things. As I look back, I am not sure how much of it was learned from lecture and books and how much of it was learned by being thrown into problems and being told to sink or swim. In a academic environment, if you sink... there is someone there to pull you out and explain to you what you did wrong and how to deal with it next time. In a corporate environment you may or may not have that opportunity... you may just get fired. I went to a school with a very challenging curriculum, and I went late in life, as a full time student with a full time job and a family. Some of the most valuable lessons I learned had to do with time management, crisis management and how to work in an environment where the best you can hope for is not to fail too miserably due to the resources at hand (or lack there of). As I look back... that has come in quite handy... probably more so than I care to admit ;-) -Original Message- From: Thornton Scott Contractor CADRE/WGTD [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 02, 2003 10:11 AM To: 'Struts Users Mailing List' Subject: RE: Does a degree matter?

Any specific technology you learn in your first year is going to be totally obsolete by the time you graduate from the program anyway, so why bother?

Page Iteration
Hi all, I want to iterate over a collection and display a certain amount of items per page and list all the further pages available (just like on google). I presume this is a feature that has been added a million times. Did a quick search on the list and I see that use of the iterator with parameter offset can be used.

RE: Page Iteration
If the data is coming from the DB, you should NOT pull down all the data and slap it in their session for paging. It's a waste of resources, especially if they found what they wanted on the first page. A better solution would be to use DB -specific bounding of the results returned, like MySql's LIMIT on SELECT queries (btw, google uses MySql). By bounding the data returned from the DB in the first place, you just return all objects received in the scope of the SELECT statement to the page. If you aren't pulling from the DB, look at JSTL under Taglibs-Standard at Jakarta's web site. Their demo war for JSTL goes over scoped iteration. -Jacob | -Original Message- | From: Brian McSweeney [mailto:[EMAIL PROTECTED] | Sent: Wednesday, April 02, 2003 10:13 AM | To: Struts Users Mailing List | Subject: Page Iteration | | Hi all, | | I want to iterate over a collection and display a certain amount of items | per page and list all the | further pages available (just like on google). | | I presume this is a feature that has been added a million times. | | Did a quick search on the list and I see that use of the iterator with | parameter offset can be used. | Is this the general approach people would recommend? | | Any good resources on showing how to do it? | cheers, | Brian - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Check/uncheck all boxes with JavaScript and DynaValidatorForm property
I have a JSP page where I have two buttons check all (to check all
checkboxes) and uncheck all.
I know that these features can be implemented with simple JavaScript
but it is not easy to associate
the Javascript with Struts components like DynaValidatorForm.
My JSP page is the following:
logic:iterate name=MyDynaValidatorForm id=employees
property=employeestype=com.Employee
offset=offset length=length
tr
td bgcolor=#EBEBEB width=10%
input type=checkbox name=selected
/td
/tr
/logic:iterate
table width=100% border=0 cellpadding=0 cellspacing=0
bgcolor=#ff
tr
td align=right valign=top width=10%
html:button property=userAction
onclick=checkAll(this.MyDynaValidatorForm.selected)
bean:message key=button.select.all//html:buttonnbsp
html:button property=userAction
onclick=uncheckAll(this.MyDynaValidatorForm.selected)
bean:message key=button.unselect.all//html:button
/td
tr
/table
script language=JavaScript
function checkAll(field)
{
for (i = 0; i field.length; i++)
field[i].checked = true ;
}
function uncheckAll(field)
{
for (i = 0; i field.length; i++)
field[i].checked = false ;
}
/script
In the Struts-config.xml file I defined the following form:
form-bean name=MyDynaValidatorForm dynamic=true
type=org.apache.struts.validator.DynaValidatorForm
form-property name=userAction type=java.lang.String /
form-property name=selected type=java.lang.Boolean[] /
/form-beans
I don't understand the aim of the attribute property in the
html:button tag.
This implementation doesn't work if someone has already done a
similar think,
thanks a lot for your help.

Isn't the scriplet free version more confusing/cryptic than the scriplet
one? I know we should avoid scriplets 110% in JSPs but what about cases
where it can save some confusion of five tags to do a simple thing?
The reason to avoid scriplets is to allow seperation of page designers and
developers dependancies but the poor page designer won't make much sense out
of either of them in this case i think and its better to give him one line
of confusion than 5.
Intersted to know your comments.
It's not just the page author you should be worrying about -- the page
compiler is affected as well. Pages with no scriptlets allow the compiler
to create much better executable code (including lifting the 64k limit on
method size that really affects pages with lots of custom tags).
Personally, I prefer the JSTL syntax for stuff like this:
c:set var=varName value=${requestScope.httpParameter}/

ViewFileAction Help
Hello all,
I am having a little trouble reading a file off the server and displaying it
to the user for viewing. I am receiving the following error from explorer:
Internet explorer cannot download ...viewFile.do?fileId=8 from localhost.
Internet explorer was not able to open this internet site. The requested
site is either unavailable or cannot be done. Please try again later.
This is some of the code that I am using in my action class:
...
try {
response.setContentType(myFile.getContentType());
response.setContentLength(myFile.getLength());
BufferedOutputStream bos = new
BufferedOutputStream(response.getOutputStream());
FileInputStream fis = new FileInputStream(myFileFile);
byte[] buffer = new byte[1024];
int bytes_read;
while((bytes_read = fis.read(buffer)) != -1) {
bos.write(buffer, 0, bytes_read);
}
fis.close();
bos.close();
}
catch (Exception e) {
getServlet().log(ViewFileAction.executeAction +
Exception: + e.getMessage());
System.out.println(ERROR + e.getMessage());
e.printStackTrace();
throw new SystemException(e);
}
return null;
The contentType and contentLength are being set correctly. Because there is
nothing to do after writing the file to the browser, I return a null
ActionForward.
Any suggestions here? Is an action the wrong place to put this code? I am
hoping to generate a popup with the file displayed in it.

[Eva Sager] RE: Does a degree matter?
What was your age when you went back to school? I am 29 (30 in August). I am married and have 2 young children (3,6). School seems to be a considerable financial/time investment. I just want to make sure I am not starting too late and doing too much for too little a result. Brandon Goodin -Original Message- From: Eva Sager [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 02, 2003 8:55 AM To: 'Struts Users Mailing List' Subject: RE: Does a degree matter? This brings up a good point... if all you get out of a degree is learning specific technology... in a fast changing world you might get left behind. If you learn how to learn technology... if you learn another way of thinking... then you just might have something. My degree is in Computer Engineering and the courses that really taught me something were the courses that taught me how to solve problems, how to learn new technologies, and how people and technology relate. The courses that taught me about technology X didn't mean a thing, because technology X isn't even around anymore... or has changed so much that what I learned isn't relevant anymore. I guess what I am saying is that it might not be a question of Does a degree matter?, but What should I be learning? and How can I challenge myself?. I don't think that my degree by itself has helped me all that much... but the things I learned while getting it were invaluable. I have worked with many people who become absolutely paralyzed by complex problems, while getting my degree I learned to deal with these things. As I look back, I am not sure how much of it was learned from lecture and books and how much of it was learned by being thrown into problems and being told to sink or swim. In a academic environment, if you sink... there is someone there to pull you out and explain to you what you did wrong and how to deal with it next time. In a corporate environment you may or may not have that opportunity... you may just get fired. I went to a school with a very challenging curriculum, and I went late in life, as a full time student with a full time job and a family. Some of the most valuable lessons I learned had to do with time management, crisis management and how to work in an environment where the best you can hope for is not to fail too miserably due to the resources at hand (or lack there of). As I look back... that has come in quite handy... probably more so than I care to admit ;-) -Original Message- From: Thornton Scott Contractor CADRE/WGTD [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 02, 2003 10:11 AM To: 'Struts Users Mailing List' Subject: RE: Does a degree matter?

These are database specific and probably won't work anyway for queries that require things such as order by, etc. In JDBC there is a call setMaxRows() that limits the total set of data returned from the database.

The scripting language in Exadel is Java. In general, we use similar technique to JSP. We generate code on-the-fly, compile and execute it. That gives really nice feeling, when you work with Exadel it feels like VB. Developers begin to use typical VB scenario write something, try it, fix it, try more etc. If anybody has some interest in our ideas feel free to download trial version of Exadel from here: http://www.exadel.com/products_webflowengine.htm You can try to get this feeling, and this is NOT commercial! I really think that some ideas from Exadel can be incorporated into Struts and Struts will benefit from it! I can put my dream list here: -well defined sub-modules, module context to store module-local data, explicit definitions of module interfaces. (all this exists in Exadel) -abstract software interface to modules, free from binding to web, ability to reuse modules from outside using WSDL and Java interfaces (exists in Exadel) -use compile-on-the-fly technique for action definitions (exists in Exadel) -debugger interface, step-by-step execution on action-page level, data introspection in contexts, introspection of data goes to/from pages and actions (exists in Exadel) -GUI tool to support all this otherwise all this does not make a lot of cense. Once again, do not treat this like commercial, I do not have an intention to offend anybody, I just put there my dream list based on my previous experience, what can help me a lot with my next project.

We implements almost all business logic in controller layer, moreover - we have two sub-layer inside controller - presentation controller, which handles all page flow and input validations, and business controller - where actual business logic where implemented on high level. All this because of using our own implementation of MVC framework - Exadel. I'm not here to convince you to switch from Struts to Exadel, but I can tell you that Struts controller component is too primitive compared to Exadel. We used widely concept of module. In Exadel you can define module (we call it process) with process context and actually use it like function calls. You even can use recursion. That gives us ability to split system to modules using vertical (by functional areas) and horizontal (by architecture layer) approach. And we design system in a way where we have two horizontal layers - one (top) designed to handle page flow and all interface relater issues.

This brings up a good point... if all you get out of a degree is learning specific technology... in a fast changing world you might get left behind. If you learn how to learn technology... if you learn another way of thinking... then you just might have something. My degree is in Computer Engineering and the courses that really taught me something were the courses that taught me how to solve problems, how to learn new technologies, and how people and technology relate. The courses that taught me about technology X didn't mean a thing, because technology X isn't even around anymore... or has changed so much that what I learned isn't relevant anymore. I guess what I am saying is that it might not be a question of Does a degree matter?, but What should I be learning? and How can I challenge myself?. I don't think that my degree by itself has helped me all that much... but the things I learned while getting it were invaluable. I have worked with many people who become absolutely paralyzed by complex problems, while getting my degree I learned to deal with these things. As I look back, I am not sure how much of it was learned from lecture and books and how much of it was learned by being thrown into problems and being told to sink or swim. In a academic environment, if you sink... there is someone there to pull you out and explain to you what you did wrong and how to deal with it next time. In a corporate environment you may or may not have that opportunity... you may just get fired. I went to a school with a very challenging curriculum, and I went late in life, as a full time student with a full time job and a family. Some of the most valuable lessons I learned had to do with time management, crisis management and how to work in an environment where the best you can hope for is not to fail too miserably due to the resources at hand (or lack there of). As I look back... that has come in quite handy... probably more so than I care to admit ;-) -Original Message- From: Thornton Scott Contractor CADRE/WGTD [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 02, 2003 10:11 AM To: 'Struts Users Mailing List' Subject: RE: Does a degree matter?

It also gave me the confidence that I could brake apart any problem into sub-problems and then solve each of those sub-problems.

Re: Is Strut too primitive for really useful Controller function?
When we did it we also think only about our project goals. I realize, that we actually use multi-layer controller architecture after we did it. It comes naturally to the following: [web layer] - nothing special, just JSP with some custom tags, web developer | | [web controller layer] - used to implement all page flow logic, validations and data transformations, calls modules from business controller layer, web developer | | [business controller layer] - used to implement coarse business functions, like put bid on the sit etc., uses same flow engine, like web controller, calls business object layer, business developer | | [business objects layer] used to implement business objects and fine grained functions, like create record in history or set company address etc, use Java and JDO for implementation, business developer. This is simplistic, but close to reality picture. You see, there is two controller layers between JSP (view) and Java (model). It provides normal controller function data transformation and functional calls aggregation. Business controller layer used to define business meaningful functions by combining elements of calls to model layer and some peaces of code; it is also responsible for transaction handling. We have two developers in team I call them web developer and business developer and such division is very natural for our team.

Re: Is Strut too primitive for really useful Controller function?
No, it is not violating MVC design. This is some sort of MVCC design with two layers of controller one to implement complex View-specific functions (page flow, data validation, data transformation) and another one to implement Model-specific functions (data flow, transactions handling, function aggregation). That gives you more flexibility in both sides. That gives you ability to reuse business functions on more coarse level. In general, your implementation technology does not matter from architectural point of view. But whole point of my original post was yes, Struts is not suitable for such design, because it is too much coupled to web and Servlet container.

You're extra C is more commonly referred to as a Session Facade or Business Delegate. http://developer.java.sun.com/developer/restricted/patterns/J2EEPatternsAtAGlance.html Saying, [Struts] is too much coupled to web and Servlet container implies a criticism. Struts is a *web* tier MVC framework and makes no apologies about being tied to the Servlet API. Your business controller sits behind Struts' Actions and handles business logic so the frameworks should be complementary.
