Re: sending object with query.

[Affan Qureshi]

You will have to create a string from the collection of objects you have 
and send it as a hidden variable or query parameter(if length allows)

Hi All,

I am sending a parameter with query request in this way:

  url += &object + 'abcd';
  document.quoteListForm.action = url;
  document.quoteListForm.submit();
}

Now instead of 'abcd' If I want to pass a collection of object.
How should I do it. I tried it by replacing 'abcd' with a collection.
But it seems this is the way of passing 'parameters' not 'attributes'.
So even if I pass a collection in this way I am getting string representation of 
collection, not the collection object.
How should I go about it.
Help please. thanx a lot

Re: large scale deployments

[Affan Qureshi]

Hi,
I think the isssue of scalability and a supporting large customer base is
out of scope of what Struts does. You might want to look into techniques
like clustering, load-balancing and distributed app architectures. Struts
has no feature that helps in these situations. However while Struts does not
solve any scalability problems it does not create any itself. The purpose of
Struts is to help you with some common web development problems that you
would have in any environment. In other words the ability or inability if an
application to support large customer base does not depend on Struts.

Re: Include response in the JSP page

[OT] Updateable Cache Framework

[Affan Qureshi]

We had an Application Cache implemented in our app which actually stored
frequently used objects in at application scope. Whenever that object was
modified in the DB we had to update its state in the cache too which was a
pain. I was looking for available cache frameworks that did something
similar (probably closely associated with the persistence layer) but most of
them provided "read-only" cache. I am referring to some kind of EJB
mechanism like it keeps the objects reference locked until the changes in
the persistence layer are committed and updates object states appropriately.

Has anybody had this requirement in his project? Any available caching
frameworks exist for such functionality?

Thanks for any pointers.

Affan

Re: [Nested] Order of Population of nested properties

[Affan Qureshi]

Thanks for your reply. Well doing stuff in action is the cleaner approach
unless u can use DOM (which is at least quicker). But I solved this by
moving the property one level up in the nested hierarchy. Although it
doesn't make sense there but it always gets populated before the nested
beans. Also since it is a temporary variable you don't need to worry about
its placement too much.

I'll look into the other approach when I get some time.

Thanks,
Affan

[Nested] Order of Population of nested properties

[Affan Qureshi]

Hi,
I have an implementation just like the monkey-tree example where I have a
button to add more fields in a form dynamically. The button is a Submit
button which is mapped to a nested bean's property. By default the the
button adds one set of nested (recursively) fields. I want it to add
user-defined no of rows. For that I have a text field mapped to another
property of the same nested bean. I get that value and add the specified no
of rows. It works fine but sometimes I get the following problem.

Sometimes properties are populated before the other which causes great
confusion. E.g if the 'noOfFieldsToAdd' property is populated after the
'addMoreFields' (the button) property I wont get the correct output. Also I
see that some properties are populated twice instead of once which is also a
bit confusing.

Is there any order in which the fields are populated? Can i control this? Or
maybe I am using it in the wrong way?

Thanks a lot.

Re: cancel button problem

[Affan Qureshi]

I have seen this one before as well. But I dont think it is possible in
plain HTML. So the best you could do in HTML is to place the default button
as the first Submit button on the form.
Or if you want ot use JavaScript then u might want to make use of new
key-capture events of JS. But i think you will then have to make all your
submissions thru links.

Hi,

I have an initial page where the company name is entered and that
forwards to a main page (with 3 frames) that loads the header, sidebar
and logon page.  I save a State bean in the session after the company is
validated (against a db) and then use the company name from the State
bean on the logon page.  With Konqueror and Netscape I have no problems
in getting the bean back from the session, but with Mozilla a new
session is created and I get a nullpointer exception (the bean's not
found in the new session).

I have traced the session id and find that it remains the same for
Konqueror and Netscape but changes for Mozilla.

Anyone got any ideas?

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.

Re: [NEWBIE]A very stupid question

[Affan Qureshi]

If you are creating a forward in struts config files or actions, you should
ignore the context name completely and write url as "/myAction.do". Struts
takes care of the context path itself.

 If you are creating links simply in HTML then do something like:
request.getContextPath() + "/myAction.do"

Look at the link Tags examples in the example apps that come with struts.

HTH.

Re: [Tiles] Design - Overriding items

[Affan Qureshi]

Thanks for the explanation. I have also implemented a similar solution (by
looking at the examples). The problem i am facing is the modification of
session value in the actions. I mean when the session values are modified in
each Action, it makes my code hard to maintain and error-prone. Because now
the layout logic is spread all over the place in my actions. I know this is
more of a design issue than an implementation one.

Also, sometimes I need to forward to actions but also want to pass
parameters to it in the query string. In this case I cannot use
mapping.findForward("Success"). I have to create a new ActionForward object
and provide the url plus the query string. This is again hard-coding of the
urls. Is there any way I can specify request paramters for a forward in
Tiles or Struts?

Thanks,

Affan

[Tiles] Creating SubTabs (Tabs within Tabs)

[Affan Qureshi]

Hi,
I have implemented the TabLayout as described in the examples and works
well. I want to define sub tabs under the main Tabs. So my requirement would
be like having  elements inside  elements(which is not
possible in DTD) so that I can define nested lists. How have you implemented
this in your apps?

Looking at the DTD I saw an element "putListElements". Where des this fit
in? Can this be helpful in this regard?

Also can I specify the class by
classtype="org.apache.struts.tiles.beans.SimpleMenuItem" to something more
sophisticated so that I can add some more info? What will I need to change?

Thanks a lot.

[Tiles] Design - Overriding items

[Affan Qureshi]

I have divided the modules(logical) in my application in a Tab layout. I
want to show different pages under the same tab at various points in the
application. It means the putList items change all the time. If I want to
extend and override the values inside the putList tags I have to write the
whole putList tag again in the extended definition. Is this right or is
there a better way?

I have created a bean in which I keep values for links to display in each
tab and modify them at runtime in my Action classes. I put that bean in
session and copy its properties to the TilesContext in the controllerClass
actions. The problem is that this design is not very easy to maintain and
enhance. Also I get the values mixed up in the session which makes the user
go to a wrong page sometimes. And the layout code is all over the place
instead of a single, configurable one (like the XML file).

Is this the right design I have? Any suggestions/solutions?

Thanks a lot,
Affan

PS
My Tiles Code below:

This is my basic/default definition:











..




In actions i have the following code to set the values in the session bean:
LayoutSettings settings =
(LayoutSettings)req.getSession(true).getAttribute(WebAppConstants.TAB_LAYOUT
_SETTINGS);
List tabList = settings.getTabList();
SimpleMenuItem searchTab = (SimpleMenuItem)tabList.get(3);
searchTab.setLink(returnLink);
tabList.set(3,searchTab);
settings.setTabList(tabList);

req.getSession(true).setAttribute(WebAppConstants.TAB_LAYOUT_SETTINGS,settin
gs);

1.1rc1 Error: Path index.jsp does not start with a "/" character

[Affan Qureshi]

I have been using Struts 1.1b2 and tiles in my application and have defined
forwards like:



where forward paths were JSP pages,  whithout the starting "/" for paths and
it worked ok. But this does not work when I installed Strut 1.1rc1 coz it
gave the exception:

java.lang.IllegalArgumentException: Path index.jsp?selected=1 does not start
with a "/" character

Have I been doing it wrong until now? Is this a TilesRequestProcessor issue?
I had done so, so that I can deploy my app under any context/module etc. and
have no dependency on root path.

monkey tree - must be session-based?

[Affan Qureshi]

I have been using Nested tags to create pretty complicated nested structures
in a flash. But I have a problem when the user opens multiple windows and
the session values can get messed up and the trees throw
ArrrayIndexOutOfBound Exceptions. Has anyone come across the same? How to
resolve it?

Can we make the  to pick up a ActionForm bean from the session
dynamically? I mean instead of using the name defined in struts-config.xml,
can we specify a name of formbean to use at runtime? This way we can create
'N' no. of independent trees and store in session under different names and
and the user can work with them simultaneously.

Thanks a lot.

Re: Use of Bean Default Value in Struts

Use the value attribute of the  and assign it the required

takes the value explicitly specified. e.g 
If you specify  then it will search for the
string "val" in the options list.

In ActionForm bean i have:

But this doesn't seem to work. Has anyone tried this before?

Re: Jsp code is sent to the client...?

[Affan Qureshi]

Can you show us the JSP code? This happened to me when I forgot to import
the tag libraries. Try deleting the work directory contents and restart the
server. Also make sure the extensions etc. are correct.

Hi,
I'm running a small struts(1.1b3) app in our Tomcat 4.0.6. After a few
days the jsp:s stop working. They don't seem to be processed, instead
the jsp code gets sent back to the browser.

Our bug reporting app (Scarab) is running in the same Tomcat and it
works fine.

Any ideas?

Re: How can I redirect a user to the previous page ?

[Affan Qureshi]

Save the url in session against some key and use that to forward to when
done on the second page. This way you can send the user to any page he/she

Setting Character Encoding (getting ? for ©)

[Affan Qureshi]

I am having trouble displaying special characters and hence my web pages are
unable to render characters like the Trademark or Copyright symbols.
Initially I thought it was a Tomcat problem coz it was working fine in Resin
and Weblogic. But if I place the same file outside the Struts application
(tomcat-docs or examples) it works fine. However it show '?' if plcaed
inside the Struts application.

Any ideas how can I fix this ugly problem in my app. The app is unusable
without this.

Thanks a lot.

Affan

Here is my code for the Test JSP:
<%@page contentType="text/html; charset=UTF-8"%>

Test JSP

<% out.println('\u00A9'); %>
<% System.out.println("This © is test");%>

<% out.println("This ° is test"); %>

<% out.println("This © is test"); %>

<% out.println("This \u00A9 is test"); %>  <%= "©"%>

<% out.println("This \u00B0 is test"); %>

<% out.println("This \u00AE is test"); %>

<% out.println("This \u0099 is test"); %>

Re: AW: Transforming a String to valid HTML encoding

[Affan Qureshi]

The struts html/nested tags replace these characters with the question
marks. This is probably because they are trying to use a filter. Now if I
use my own Encoding/Decoding I will have to turn struts filtring off as u
said. I can do it in  tags but I can find a way to do this in
 and  etc.

This is critical for the application to be usable.

Thanks and Regards,
Affan



It is just for Struts. Or even just for the JSPEngine.

If you want to be on the save side, you can ADDITIONALY add

in the html head.

Do you use a font in which this symbol is available?

Re: AW: Transforming a String to valid HTML encoding

[Affan Qureshi]

Hi,

I was facing the same problem in displaying the copyright and trademark
symbols. Did you find some solution for this? I shall be greatfeul if you
can share you experience with me.

What I did was I created a utility class which transforms special characters
into their HTML encodings and also decodes the same. But Struts transforms
them again e.g if I encode ˱ for one symbol Struts will encode the '&'
to & and hence my effort to encode will not work because my symbol would
become ˱. Now either I want to know if I can turn the
ResponseUtils.filter OFF or I can have it filter for my characters too (it
currently only filters 4 characters).

BTW I cam not talking about URL encoding here. I am talking about HTML
encoding for my forms and otherwise.

Thanks,

Affan

Thank you for your help, Craig.

I don't know if you got me completely right.. or maybe I didn't understand.

What I want to do is to transform the regional characters of a String like
"ü" into "ü"

The reason is, that I don't want to use utf-8, but ISO-8859-1 for my html
pages. And if a "ü" appears in the ISO-8859-1 characterset in the browser,
it is not displayed correctly in a browser using the english locale. But it
is displayed correctly if "ü" is used. (what is the name for this
format?)

As far as I could learn, java.net.URLEncoder transforms into
"application/x-www-form-urlencoded MIME format", used for the URLs. But this
format is not for the body of a html page, right?

Bernhard

ResponseUtils is only worried about filtering the characters that could
cause security problems -- it is not designed to be a general purpose URL
encoder.  For that, check out the java.net.URLEncoder class.

Re: line breaks

[Affan Qureshi]

Sorry for the last post. Actually it was a GZip filter that was not
preserving the line breaks.

But your point still holds. And that may be the reason for the equality
comparison not working quite right.

I will try to take out all line-breaks before comaprison.

Re: line breaks

[Affan Qureshi]

Well thats interesting coz I am experiencing it a bit differently. I have
line breaks in the DB but when they show values in the textarea the text
appears as one block. However if you enter line breaks in the textarea and
then Save the data it goes into the DB *with* the line breaks. But when it
is loaded back again the line-breaks disappear.

This has to do something with the population of HTML controls with the data
because my form-bean values do have line breaks (in setters and getters).
Also if I print these values using  I get the line breaks as in
the DB. But not in case of . Quite strange.

I think the consensus is to use one Action class per Action form (bean).
For a simple update like you describe, it would be natural for the same
Action to update the database (actually, call a DAO or EJB) whether it's a
new user or new information for an existing user.  Work through your use
cases and I think it will become apparent what Action classes are
appropriate for specific responsibilities.

We are deciding about how to use action classes in our project.

Is it a problem to let developers use the same action class to handle
different operations?

Example:

The action UpdateUserAction could be used to insert a new user or to update
the data of an existing user. Is it a problem? Or it's better to have
InsertUserAction and SaveUserAction. They do almost the same thing so I
think they could be same.

How to reset session-scoped Dyna bean values

A rather basic question: How to reset/empty the property values in a session
bean when I get to page 1 in a wizard type interface?

I have a wizard type interface where I need to retain values throught
four/five screens. But when I want to start a new process from screen 1 I
get the same values back that I had entered in the prev process. How can I
reset them? My form bean is a DynaActionForm and I have tried setting the
initial property to "" and "false" but this does not seem to work. What am I
doing wrong?

Thanks in advance..

Setting chehckbox state for DynActionForm

[Affan Qureshi]

I want to set checkbox states for properties of a DynaActionForm. What
values and types should I set for form bean defs in struts-config? What
values should I get in Action after submitting the form?

I have tried setting property types to java.lang.String, boolean and
java.lang.Boolean type. It showed all checkboxes as "on" even though I had
set the property to "on" in the prececding Action. Then I used  in JSP but this time the
display was fine but the values i was getting were not correct i.e the only
checked checkbox was the one that I had hard-coded in JSP.

Note: All checkboxes are not related. So multi-box is no suitable here i
think

Any ideas.

Thanks,
Affan

This has been asked many times before as well.

In Action before forwarding to the JSP:

MyBean bean = new MyBean();
bean.setMyAttribute("my value from somwhere");
request.setAttribute("formBeanNameInStrutsConfig" , bean);

line breaks

[Affan Qureshi]

I am using Struts 1.1b2, Tomcat 4.1.12 LE, on Win2K.

I have a strange issue. I have a TEXTAREA type control that gets populated
from values in database. The value in the database has some line breaks. I
store that value in a variable called: "OLD_VALUE". Then I display the value
in the TEXTAREA and when i get it back(from form-bean) after the form is
submitted (without changing the value) i store it in a variable called
"NEW_VALUE". The two DON'T evaluate String.equals() to "true". When I paste
them in notepad I see that OLD_VALUE has line-breaks while the NEW_VALUE
does not have line breaks.

Has anyone else faced the same problem? I guess it has something to do with
\r and \r\n for line breaks on different platforms.

BTW the data in the database is saved in Oracle 8i through a Swing
client/server app. The App-Server for Swing app is Weblogic on Solaris for
SunSPARC. Then the data gets imported to XML and then to MySQL on Win2K.
Then the Struts app loads and display/edits it in the above form.

Thanks and regards,

Re: multiple parameters for dispatchaction

Of course. Set up a link like:

In the action class you can get the value of the primary key by
request.getParameter("pkey")

Was that the problem or am I missing something?

Re: Dynamic Forms

You have quite a few options for this scenario. Either use Map-backed form

Re: Multiple forms in session [WAS: RE: how to send actionForm fromone action to another action]

[Affan Qureshi]

Is there a way to instantiate multiple instances of actionForm beans under
different names? Also the  and action should lookup beans using a
dynamic string rather than one from struts-config.xml. We can create unique
names by appending some Id to the names. This way we might be able to avoid
name conflicts and still be able to work with multiple forms simultaneously.
Is this possible in any way? Or what is a better solution for this?

I dont want to make the bean request-scope because session-scope beans allow
for better functionality. BTW I am using Nested tags in this case.

Thanks and regards,

Affan

Re: Cascade actions execution!

[Affan Qureshi]

Have you tried writing reset code in FromB.reset()?

Or perhaps you can create FormB yourself in ActionA and store it in the
appropriate scope explicitly (although I have never tried this myself). I
think the request parameter with the common name is the problem here. Can
you forward to ActionB by somehow overriding the value of that request
parameter? Or (of course) you can name the parameters differently.

Tell me if it works?

Simultaneous editing of a session-scoped ActionForm bean

[Affan Qureshi]

I have a session scoped ActionForm bean "productBean" which has a nested
hierarchy of objects. If the user opens two windows for the same page for
different products the bean in the session gets overwritten and may cause
corruption of data. One way is to error out if the user has a different
product on the screen than the bean in the session (by comparing the
productIds). But I wanted to maybe define multiple beans with different
bean-names by appending the productId with the bean name. In that case the
form should lookup the bean identified by a dynamic label rather than the
one defined in struts-confg.xml. Is this possible? Can I instantiate
multiple instances of a form bean even if declared only once in
struts-config.xml? Or do I have to bypass the struts-config declaration
altogether somhow?

Has anyone done this in a better way? Any best practices in this case?

Thanks a lot.

Re: Pre-populating DynaActionForm Bean

[Affan Qureshi]

I have a similar scenario but in my case the sending action does not have
the same form bean bean associated as the destination. So what I want to do
is to instantiate a form bean which the JSP is expecting and put it in the
request scope.

Here is my code:

DynaActionForm form = new DynaActionForm();
form.set("productId", String.valueOf(acc.getProductId()));
form.set("mfrPartNumber", acc.getAccessoryProduct().getMfgPartNo());
form.set("description", acc.getAccessoryProduct().getDescription());
form.set("notes", acc.getNotes());
req.setAttribute("accessory", form);

This is the JSP to which I am sending this request:





Save Accessory


In struts-config.xml I have the following def for action saveAcc.do


This is the error I get when submitting to the JSP:
java.lang.NullPointerException at
org.apache.struts.action.DynaActionForm.getDynaProperty(DynaActionForm.java:
545) at org.apache.struts.action.DynaActionForm.set(DynaActionForm.java:361)
at com.etilize.cms.web.actions.AddAccessoriesAction.editAccessory ..
(more...)

I am sorry if this has come up earlier but I could not find one.

Thanks a lot.

Re: monkey tree problem

[Affan Qureshi]

Are you talking about JavaScript click event here? The names of the buttons
are generated using the nesting scheme like:
name="bean1.nestedBean1.nestedBean2.button1". Or if they are indexed (in an
array) it uses the array syntax like
name="bean1.beanColl[2].nestedBeanColl[4].button1".

Have you tried using the onclick attribute of the  tag. You
can pass this button into the JavaScript function and use the above scheme
to know which button was clicked.

Is there a way you can accomplish the same functionality (like the
monkey-tree example v2) by making the bean request-scoped?

Subject: monkey tree problem


Hi All,

I have a requirement to generate the tree structure from the collection
object.

right now I am using the monkey tree to generate the tree structure for the
same.

The tree is generating fine. But, the problem is that I want to catch the
click event i.e. which node is clicked so that I can get the node name that
is clicked.

Is anybody is using monkey tree?

please help me to resolve this problem, also if there is any alternate
option let me know.

thanks a lot,

Amit Badheka.

Re: logic:iterate

You can do it manually by keeping the collection and state variables in the
session which indicate the page nos and the current status of the
collection. However there are some Tag Libraries available taht do just
that. Check out Struts-Layout and Ed Hill's TagLibs on the Struts resources
page.

theKB Example (prev: Complicated Web Interfaces?)

[Affan Qureshi]

Nested Tags really helped me in achieving what I had nightmares trying to
accomplish otherwise. I have something similar to what we have at
http://www.keyboardmonkey.com/StrutMonkey/MonkeyStruts_v2.jsp
but in my case the Adding/Deleting object (corresponding to BunchBean ) is
pretty dynaimc i.e you dont know in advance the properties of the
BananaBean. However it works pretty sweet.

The problem is screen refresh. If I delete a node and click Refresh then
there is an ArrayIndexOutOfBoundsException because the request is resent to
delete a node that is already deleted. I have disabled the user to delete
the last Banana (i.e the user should not be able to delete the last Banana).
But the refresh problem I dont get. In the example it just deletes the last
Banana if I refresh until all bananas are gone. But at least it does not
show an exception.

I have even tried to catch and ignore the error at the
Action/RequestProcessor but it did not work too well. (Maybe i did not
implement it correctly).

Has anybody come across this?

Thanks for a great example.

Re: Complicated Web Interfaces?

[Affan Qureshi]

Well. Depends on what logic you want to implement using your JavaScript. If
it pertains to display logic I think there is no harm in using JS. But if it
also specifies rules (like which node can go uder which tree and so on) then
I guess you have a point and need to re-assess the maintainability of the
app in case og Business Rule changes.

Quick Question: rtexprvalue for onclick event in

[Affan Qureshi]

I want to use a nested bean property in the onclick attribute of the
nested:submit. Since i cannot refer to bean properties in onClick
attributes, I declared a pageContext variable using nested:define. Then I
used that variable in the onclick attribute.

I want to accomplish this:
', this.form)">
Add Params


But I get te following error:
[ServletException in:/webpages/editSpecs.jsp]
/webpages/editSpecs.jsp(58,176) jsp.error.attribute.noequal'

I think i cannot give both a <%= %> and a String in the attribute value as I
have done above. But if I remove the String so that my code becomes:
onclick="<%= (String)pageContext.getAttribute("attributeId")%>", it woks
correctly. Is there a work around for this?
Thanks

This is shown in Tiles portal example. Works pretty well for simple
purposes. Look at the place where you can add, delete, change tiles in the
portal setup. You dont have to use tables like struts-layout. You can use
some HTML select lists and some simple JS to manipulate them.

Struts is just another Web application and runs servlets and JSPs. You need
to come up with your own way to intergrate your stuff (JavaScript, Applets)
with it. Struts does not provide you with an IDE. It provides you with a
framwork to make your work easy.

KB-Monkey-example uses a fixed object model (i.e it knows what fields are
there in each object). However I think if you want the tree to be dynamic
you can use the same technique with your own object model (which seems to be
dynamic in content). The key to adding and deleting the nodes is the way the
button clicks of "Add" and "Delete" are handled in a nested environment.
Nested tags enable you to remember the context of added and deleted
objects/nodes. You can use Map-backed properties for dynamic form-fields.

But one issue with the monkey example is that it refreshes the page if I
want to add/delete an object/node. Wouldn't it be more efficient to use
JavaScript for the purpose? I mean why resend the request back to the server
if you only want to add "blank" fields? If anybody has accomplished this I
would be glad to know.

forwarding to Actions expecting ActionForm

[Affan Qureshi]

I want to forward the request from my Action to another action which expects an 
ActionForm instance for processing. But my current Action does not have access to that 
Form. Can I instantiate an ActionForm and store it in the request/session scope on the 
fly? 

I have a search page which displays results from where I can view details of the 
results. On the details page if I click "Cancel" I want the user to come back on the 
Search Results page but with the same results opened. 

Also if the user clicks on Search Tab from anywhere in the app I want the specific 
(last) search results displayed.

Any ideas? Thanks a lot.

Re: help needed with DynaActionForm

[Affan Qureshi]

I want to accomplish dynamic property defs by specifying properties in a

I define a property in EditProductsAction by using
DynaActionForm dynaFrom = new DynaActionForm();
dynaFrom.set(propertyNameFromDB, new Integer(55));
and in the JSP i try to refer to this as:

I get the NullPointerException whose stack trace is given below. It is
occuring inside DynaActionForm.java on the call to getDynaClass()

Re: An example of dynabean !

[Affan Qureshi]

I guess i can do this by overriding the processPopulate() method of
RequestDispatcher.But the problem is that I want this to take place in only
a special case when my form is a dynamic one. Otherwise I want to use the
default functionality. A request attribute can help but that would be a bit
patchy.

I used to do this by using a naming convention on control names (e.g fld_<%=

Re: [TILES] Dynamically overriding Tiles Definitions

[Affan Qureshi]

I want to modify the Attributes in a tiles Definition from my Action
classes. Is this possible? I have tried the following code inside the Action
class but do not get an Attribute against the name, instead I get a null.

ComponentContext context = ComponentContext.getContext(request);
java.util.List list = (java.util.List)context.getAttribute("tabList");

Is it because it is request scoped? Can i make it session-scoped? Also I get
an empty iterator when I try to traverse the list of attributes in the Tiles
Context.

Iterator iter = context.getAttributeNames();
System.out.println(iter.next())
System.out.print("Printing Attrbutes:");
while(iter.hasNext())
{
System.out.println("Attribute"+ ((String)iter.next()));
}

My tiles definition is given below. Thanks a lot.

Nested layouts (Panels inside Tabs)

[Affan Qureshi]

I have a Tabs Layout setup and inside a tab I have another layout with two
panels(menu and content). This is my definition:


 
 dfs
 s
 
 
 
 
 
 


The link to "Template" i.e the template.jsp file follows a simple layout:






The problem is that when I click on any link inside one of the panels in
templateTile.jsp or any other file, it breaks out of the Tabular layout and
displays it as just two panels. This problem can be reproduced if you run
the tiles-documentation example and go to
http://localhost:8080/tiles-documentation/examples/tabs.jsp. Now here if you
click on any link in the menu the page will open outside the tab layout.

The hyperlinks in my "Menu" panel point to Action classes. I am forwarding
requests from the Action classes to Tiles Definitions.

What should I do to tackle this problem?

Also can anyone guide me to a resource for Nested Tabs?

Thanks for your time.

How to get the tiles-def.xml (and struts-config.xml) reloaded w/out restarting

[Affan Qureshi]

If you reload the application only (using Tomcat Webapp Manager) I think you
won't have to restart the server but just reolad the app.

However can I reload it without even restarting/reloading the Application?

I would also like to know how can we reload struts-config.xml without
restarting the server or even reloading the app.

Thanks

TLD not found

[Affan Qureshi]

I get the following error when running the JSP in tomcat 4.1.12 on W2k

org.apache.jasper.JasperException: null(-1,-1) File "/struts-layout" not
found.. (and the rest of the stack trace)

In web.xml I have

/struts-bean
/WEB-INF/tld/struts-bean.tld
  


On top of JSP I have
<%@ taglib uri="/struts-bean" prefix="bean" %>

However it worksfine if i give a full path in the JSP as
<%@ taglib uri="/WEB-INF/tld/struts-bean.tld" prefix="bean" %>

But according to TagLib Specs the first one is also valid. Or is it not?

else

Re: *reset* why is it not being called

[Affan Qureshi]

I think you should use JavaScript function for your req. and change teh tye
of the "Reset" button to BUTTON and call a JS function on its click().

- Original Message -
From: "Joe Barefoot" <[EMAIL PROTECTED]>
To: "Struts Users Mailing List" <[EMAIL PROTECTED]>
Sent: Thursday, October 24, 2002 5:11 PM
Subject: RE: *reset* why is it not being called


If you mean that you are using  or , and
this is the button you are clicking, then there is no request being made to
the server.  The reset button is client-side;  the browser just resets the
form to whatever the values were at the time the form was last submitted.
That's why they "magically" return. :)

The reset() method in your ActionForm is *only* called when you do a submit
to an action URL that uses this ActionForm.  The reset *button* in html
forms doesn't do a submit.  So, if you want your reset() method to be
invoked, you need another mini-form, which only contains a submit button
(you can label it reset, clear, or whatever) and maybe a hidden value or
something to instruct your action to not do anything (i.e., action=reset).
In your action, just check for this value in the form or request, and do
nothing.  The reset method in your form will already have been called.

Note:  Do NOT use another submit button in the same html form as the one
containing your entry fields (use a separate form), as the values they
contain will be submittedand since Struts calls the reset() method
*before* populating your form, the form will still get populated with the
'old' values, negating the effects of your reset logic.


hope this helps,
Joe

Tiles vs Template Tags

[Affan Qureshi]

I want the layout of my application in such a way that if I want to change it I have 
to make changes in a minimum number of places. What should I use Tiles or Template 
Tags? Can someone highlight the difference between the two?

Also when iterating a collection i want to check whether a value is null or not. 
Should I use  tag? Or how else?

Thanks a lot.

Re: Duplication of code in Business objects and Action forms

[Affan Qureshi]

Do you intend to pass the Data Object back and forth between the
presentation layer and the Business layer? I thought it would be a nice idea
to pass only the view of the data in/out of the Business layer and the
presentation layer.

I would go more for what Ronald specified.

Re: Bean Utils - Help needed

[Affan Qureshi]

The org.apache.commons.beanutils package contains several classes that are
used throughout the Struts framework. From the standpoint of the Struts
framework, the two most important are the BeanUtils and PropertyUtils
classes.

As you might have guessed, the BeanUtils class is used with JavaBeans. The
Struts components primarily use just three of the methods in the BeanUtils
class:

· populate()

· getProperty()

· getArrayProperty()

The populate() method is used to fill a JavaBean with data, using a map of
key/value pairs. The method signature for the populate() method is shown
here.

public static void populate( Object bean, Map properties )

  throws IllegalAccessException, InvocationTargetException;

The getProperty() method returns a String representation of the property
stored in the variable with the name that matches the value of the name
parameter.

public static String getProperty( Object bean, String name )

  throws IllegalAccessException, InvocationTargetException,
NoSuchMethodException;

Regardless of the type of property that the name argument references, it
will be converted and returned as a String.

The getArrayProperty() method returns the value of the specified array
property of the specified bean, as a String array. Here is the method
signature for the getArrayProperty() method.

public static [] getArrayProperty(Object bean, String name)

  throws IllegalAccessException, InvocationTargetException,
NoSuchMethodException;

Although the Java language provides reflection and introspection as part of
its core API's, the BeanUtils class provides convenience wrappers around
these API's.

The other class that is used by the Struts framework is that PropertyUtils
class. However, only one method is currently used, the getProperty() method.

public static Object getProperty(Object bean, String name)

  throws IllegalAccessException, InvocationTargetException,
NoSuchMethodException;

The getProperty() method in the PropertyUtils class returns the value of the
specified property, without attempting to convert the type.  Much of the
code that is in the PropertyUtils class was originally implemented in the
BeanUtils class. It was moved to its own class due to the size that
BeanUtils was becoming.
