How to call multiple submits in a jsp form(in STRUTS other than using javascript)
Hi, Is there any better way to call multiple submits in a jsp form using Struts without using javascripts. I have to call diffrent actions on each submit,(say listing , deleting and adding) , this can be easily done through scripts , but what if scripts is disabled. Does Struts have any better solution.

In these cases, if I don't manually validate and then use the setUp() method to repopulate some Request scope stuff, I'll usually just stick the Lists in Session scope. If memory performance is a super major concern then I stick to the manual validate in the Action and repopulate the request as needed with the Lists it needs.

I could use some Struts-EL/JSTL tag help, please.
I have a Map with each entry having a String as the key and a bean array

I need two iterations, one nested inside the other.
For the outer iteration, I want to iterate the keySet of the Map. I
don't know what the keys are going to be or how many there will be.
Within that iteration, for each key in the keySet, I need to iterate
over the buckets of the array that is the value for that key.
To make this more clear, let's say I will produce a table of tables,

Well, sort of. If you use the forward *attribute*, Struts is going to forward total control over preparing the response (for the current request) to whatever servlet resource is identified by the URI. Since there's no way for such a servlet to return an ActionForward, there won't be any subsequent forwarding based on elements (either local or global). > I guess my confusion was over if you could//would want > to use both the element and attribute at the same time -- something you > can't do really because it would result in two calls to > resultdispatcher.forward.

Re: Javascript question re: dynamically generated input type='text' controls
Problem solved. It is possible after all to use input control names
containing equals or semicolon or any delimiter as follows:
document.formname.elements("value(number=1480;countryCode=USA;templateNumber=7;typeCode=STAGE;languageCode=EN;idTypeCode=MODE:)").value
= "";

Jim, thanks for the reply, but I am having some trouble understanding what you did. How does the viewContent parameter get used? Also, just for clarification, view.jsp has the sub-layout in it and singlePanel.jsp contains the content I wish to insert into an area in the layout.

The original motivation was to allow you some flexibility in how actions (from the viewpoint of the rest of the application) are implemented ... for example, if you have a charting servlet available, and it accepts request parameters to configure it's behavior, you could leverage the validation part of Struts to check the request parameters, but forward to the charting servlet in order to actually produce the graph.

RE: Displaying bean values within tiles
Ok, let me get this straight. I'll go down the list and you see if I
have each step correct:
1. Put a string in some scope, like the request scope:
request.setAttribute("thispagetitle", results.getWhatever());
2. In my "results" page, I want the title of that page to be the value
that I sent back as "thispagetitle", so I will do this:
Which will put the value of "thispagetitle" into "pagetitle".
3. Then, in my template file, whatever is put into "pagetitle" will be
displayed:
Results:
...which should display getWhatever() in step #1.
Is that the way this thing works?
Thank you for your help!

Nested tile definitions w parameters
We have a (pretty common) definition similar to this: We then have a definition that extends the first definition, like this: Basically what we are trying to achieve is to use the view.jsp as the content that gets included by the master.jsp layout page. But the view.jsp page also has a tag in it - kind of like a sub-layout situation. We want to include the singlePanel.jsp page inside the view.jsp page. When the page renders, we get an error stating that there is no value for "viewPane" - like it is not getting passed or something. Are we doing something wrong, or is this "nested tile definitions" use case outside of Struts current capability?

Re: Who calls the validate method ???
Rick, as i said i really like your approach, but there are some input pages that are really really simple, so there's no need for doing this. Then, in this cases, i'd like to call some other method just after validate is called from Struts. That's why i was wondering "who" calls it. --- Rick Reumann <[EMAIL PROTECTED]> escreveu: > Leandro Melo wrote: > > > Hi, > > could anyone tell me who calls the validate method > of > > the ActionForms? > > I think "you" should:) I find it's often more > beneficial to not rely on > Struts calling this validate() method and instead > you should call this > manually. > > From my other post: > > - when validation fails and you are back on > the initial form you > will not have access to the previous set request > attributes.

include vs. forward attributes in struts-config action element
Hi all,
I'm a bit puzzled about the processing of includes and forward
attributes in the struts-config action element vs. the forward element
under the action element
I understand why the forward element is there (and I use it quite a lot
, too) but I got a bit confused when I was looking around in the
RequestProcessor.process method:
public void process(HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
...
// Process a forward or include specified by this mapping
if (!processForward(request, response, mapping)) {
return;
}
if (!processInclude(request, response, mapping)) {
return;
}
// Process the returned ActionForward instance
processForwardConfig(request, response, forward);
}
It looks to me like including a forward attribute in the action element
will break any forwards you want with a forward element as it calls
RequestDispatcher.forward - which forwards on the output stream, etc...
This question came up when I was digging up info on RequestDispatcher
forward vs. include and found refrences to these attributes, but no real
examples. Does struts still support the forward and include attributes
as a legacy or a servlet api spec thing? Or what?
Thanks
Michael Finger

See, I disagree with this entirely. Pick lists can be put into application scope, if they are small enough. Use the Fast Lane Reader pattern if they aren't. If you need to customize the list based on whatever, then you can that through the list bean ( I wouldn't recommend just putting a list in application scope, rather a bean containing a list to support this kind of setup) and then set the input parameter. If they aren't application in scope, then put them into the session. I know that some people don't like putting things into session/application scopes because of memory.. however memory is not only cheaper then developer time, it's expensable too! - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

The problem you are describing comes up a lot on this list - when
validation fails and you are back on the initial form you will not have
access to the previous set request attributes. It is for this reason
that I now rarely ever set my mapping validate to "true" and instead
call validate() from my Action after the form submits. The reason for
this is when validation fails (ActionErrors/Messages return) I can then
call a private setUp() method in my Action that is used to set up my
form with any other request attributes that should always be there.
For example, a common complaint is: "I have a List that I set up in
request scope that is used on the form for the user to select an item,
but when validation fails this List will not be there." To get around
this problem, simply call validate() manually in your action and if

It's actually the RequestProcessor.

Re: Loosing request attributes
Erik,
i'm not talking about form attributes, that's what i
said in my last e-mail.
I'll try to clear it out.
Suppose a user submits a request that is handled by
MyActionDoSomething. Then this action sets a request
attribute like this:
request.setAttribute("MyObject", obj);
and forwards the request to the page
myPageDoSomeOtherThing.jsp, wich has some inputs for
the user to fill in.
This page (myPageDoSomeOtherThing.jsp) uses the bean
"obj" that was set in MyActionDoSomething.java ok !?
Now suppose the user submits wrong information in
myPageDoSomeOtherThing.jsp, what will cause the
validate method in the associated ActionForm to return
some ActionErrors. BUT when the ActionForm send this
page back for the user to re-input data, the bean
"obj" that was set at the very beginning in
MyActionDoSomething.java is NOT present anymore!
I think now it's clear that i'm not talking about the
formBean attributes, right !?

Displaying bean values within tiles
Hi all, I hate to ask a real, boring, non-OT question on a Friday, but I am working with a Struts application in which I am using tiles to organize my views. What I want to be able to do is pass in a bean with a String (or, "string beans" for all you farmer types out there) into my tiles setup and have that value displayed in my view. I have my tiles definitions in tiles-defs.xml, and of course I have a file template.jsp which handles my layout. I have horsed around with using the tag with the String value, but I can't seem to get that to work -- for the page I want to display it on, it either displays the default value for the page as I have it set in tiles-defs.xml, or it doesn't print anything at all. I suppose my question could/should be how and where would I use this useAttribute tag, as it seems to be the solution to my problem. Thanks for your help, and I look forward to receiving your responses. Best Regards, Andy - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Losing request attributes
In order to keep the actual entries that the user typed in (so they
don't have to retype everything if they changed a bunch of things) I
usually put the entire form and errors into request if there are
errors.
Then you need to make sure that your populate action checks for
presence of the form in request and overrides the DB entries with the
ones in the form.

Javascript question re: dynamically generated input type='text' controls
Hi, I am developing a page containing dynamically generated input type="text" controls where their names consist of multiple composite keys. The name of the input type="text" controls, however, can not be referenced correctly using javascript. For example, I have the following html input tag: The following javascript won't work because the control name contains = and ; and : as follows: document.formname.number=1480;countryCode=USA;templateNumber=7;typeCode=STAGE;languageCode=EN;idTypeCode=MODE:.value = ""; I only have one other idea how to solve this problem. Instead of control names containing the multiple composite keys, instead use a simple valid name. In the action, map the valid name to the multiple composite keys. Does anyone have any other ideas how to solve this? Thanks in advance. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Losing request attributes
You can point the "input" to an action which will populate the request with
the attribute(s) you need, and then forwards to your form.

RE: Loosing request attributes
This is because when the user submits the form, that already starts a
different request, so the request attributes are no longer there.
In your mapping for the action where the form gets submitted to, where does
the input attribute point to?

Do you
RE: Loosing request attributes
As i replied many times for this topic, i'd like to
expose the situation again and in DETAILS.
Suppose a user submits a request that is handled by
MyActionDoSomething. Then this action sets a request
attribute like this:
request.setAttribute("MyObject", obj);
and forwards the request to the page
myPageDoSomeOtherThing.jsp, wich has some inputs for
the user to fill in.
This page (myPageDoSomeOtherThing.jsp) uses the bean
"obj" that was set in MyActionDoSomething.java ok !?
Now suppose the user submits wrong information in
myPageDoSomeOtherThing.jsp, what will cause the
validate method in the associated ActionForm to return
some ActionErrors. BUT when the ActionForm send this
page back for the user to re-input data, the bean
"obj" that was set at the very beginning in
MyActionDoSomething.java is NOT present anymore!
I think now it's clear that i'm not talking about the
formBean attributes, right !?

Missing, as in the when the screen gets re-rendered they're missing or the data is missing? If the data is missing are you using primitives in your action form or Strings? If you're using primitives then of course your data is misssing.

Re: [OT] DAO ... where to draw the line?
Matthew J. Vincent wrote:
Hi all,
Thanks for the info. Here's another issue.
What if I have an employee search screen that wants to show only some
of the information of an employee (not all). What do you do then?
1. Instanatiate an Employee object and only fill in the relative
information? Keep in mind that this could be just employee name and
location on the search results screen and then when the user chooses
which employee to view I need to get all of the employee information.
2. Instantiate an Employee object and fill out all the information
even though you won't be needing most of it on the search results screen?
3. Create 2 DTOs, one called Employee and one called EmployeeSearch
DTO. The EmployeeSearch DTO only stores what needs to be shown on the
search results screen and the EmployeeDTO holds all the information
for what needs to be shown on the detail screen?
4. Something else...
Thanks!

hi matthew,
I wont say that you go with one or other of your approaches.
It depends upon type of assosciation that 2 entities may share. They
may have aggregation or composition relationship. Depending on that
your DAO implementation will decide that you need to get ONLY id or
the composite objects.
Let me explain.
Say you have class named ORDER ad ORDER_DETAILS. (consists-of
relationship) Order without order details is nothing. So you may get
the OrderDetails object as well when you get Order.
Now say you have EMPLOYEE and DEPARTMENT. (has-a relationship)
EMPLOYEE *may* still exists with or without department. So you may
get only id of department and later fetch the department.
Think in employee table, you have relationship (reports-to). If you
specify this relation as composition, you may go on fetching the
objects all the way up to the organization chart ;-)
Do i make sense?

Subject: [OT] DAO ... where to draw the line?
[OFF TOPIC]
I know this is a struts forum, but as struts developers using DAOs,
where do your DAO implementation draw the line?
For example:
Let''s say I have three tables:
Employee (contains employee_id, employee_name, and dept_id)
Department (contains dept_id, dept_name, loc_id)
Location (contains loc_id, location_name)
How deep do your classes go to replicate the data?
Do you do this...
public class Employee {
private int id;
private String name;
private int deptId; // just the id
// .. implementation details
}
or do you do this
public class Employee {
private int id;
private String name;
private Department dept; // all of the data
// .. implementation details
}
and so on and so on. Class Department has the same type of
problem. Does it hold just the id for location or a variable class
Location?
Should DAOs just fill in the id (keys) so it is up to the
application using the DAOs to get the Employee class, then the
Department class, and the the Location class like:
Employee emp = EmployeDAO.getEmployee(1);
Department dept = DepartmentDAO.getDepartment(emp.getDeptId());
Location loc = LocationDAO.getLocation(dept.getLocId());
System.out.println(emp.getEmpName() + " works in " +
loc.getLocationName());
or
Employee emp = EmployeDAO.getEmployee(1);
System.out.println(emp.getEmpName() + " works in " +
emp.getDept().getLoc().getLocationName());
Now this is just a simple example, but where do you draw the line?
It's possible to go on and on and on and cycle back to employee...
Any thoughts, links, tips, best practices, whatvere would be helpful!
Thanks!
Matt

Read only iterate?
I've been totally defeated in my attempt to alter an html:text
element inside a logic:iterate tag. There must be a way to
accomplish this, but I've been beating my head against the wall
for three days now without making progress.
I have simplified the problem substantially from the initial page.
What I have now looks like this:
-
[ Submit ]
Problematic Input [0 ]
Problematic Input [1 ]
Functioning Input [A Value ]
-
The lines containing "Problematic Input" were generated by a
logic:iterate tag, which successfully fetched the list of objects from
the form bean. The last line, containing "Functioning Input", was
generated outside of the logic:iterate tag. Actual contents of the
jsp page, bean, etc., are attached.
What happens at runtime is that when the JSP page is rendered, the
text fields for all three rows are successfully and correctly fetched
from the form bean, but only the last row can be changed. As the log
shows:
INFO [org.apache.struts.util.PropertyMessageResources] Initializing,
config='org.apache.struts.taglib.html.LocalStrings', returnNull=true
INFO [problem.ProblemBean] initializing entries
INFO [problem.ProblemBean$ProblemItem] setInteger_value to 0
INFO [problem.ProblemBean$ProblemItem] setInteger_value to 1
INFO [problem.ProblemAction] show
INFO [org.apache.struts.util.PropertyMessageResources] Initializing,
config='org.apache.struts.taglib.logic.LocalStrings', returnNull=true
INFO [problem.ProblemBean] getEntries
INFO [problem.ProblemBean$ProblemItem] getInteger_value
INFO [problem.ProblemBean$ProblemItem] getInteger_value
INFO [problem.ProblemBean] getWorking_perfectly
INFO [problem.ProblemBean] setWorking_perfectly to 'mutated'
INFO [problem.ProblemAction] update
INFO [problem.ProblemBean] getEntries
INFO [problem.ProblemBean$ProblemItem] getInteger_value
INFO [problem.ProblemBean$ProblemItem] getInteger_value
INFO [problem.ProblemBean] getWorking_perfectly
The page is initialized properly. All three values are fetched from
the form bean via the expected get methods. The html form is properly
populated and displays the expected values (0, 1, and "A Value").
The three fields are then changed (to 5, 5, and "mutated") and the
submit button is selected at the point in the log file where I have
inserted the annotation.
This causes the form to be submitted to the Action, causing the set
method for the field "working_perfectly" to be invoked (as it should
be), but the set method for the two fields in the logic:iterate tag is
not invoked. And I don't know why. And I can't seem to get them to
be invoked, either.
So . . . the magic isn't working. Something must be needed to tell
the generated servlet not to treat these two properties (inside the
logic:iterate tag) as read-only. What should it be? How can I get
these properties to be updated in the form bean as the
"working_perfectly" property is?
Like I said -- I've been beating my head against this problem for
three days now. There's just got to be a way!

Re: Need help with layered Map iteration in JSP
supports a "varStatus" attribute. The value of that atrribute is a
String that names an instance of javax.servlet.jsp.jstl.core.LoopTagStatus. The
LoopTagStatus instance has nested visibility so that it's only available within
the enclosing tag. LoopTagStatus exposes a number of properties,
but the one you're probably interested in is "index":
..
<%-- ${status.index} is the current index --%>
...

Re: Need help with layered Map iteration in JSP
How can I refer to the index of the current iteration with c:forEach
(analogous to the indexId attribute to logic:iterate)?
Thanks,

I could use some Struts-EL/JSTL tag help, please.
I have a Map with each entry having a String as the key and a bean array
as the value.
I need two iterations, one nested inside the other.
For the outer iteration, I want to iterate the keySet of the Map. I
don't know what the keys are going to be or how many there will be.
Within that iteration, for each key in the keySet, I need to iterate
over the buckets of the array that is the value for that key.
To make this more clear, let's say I will produce a table of tables,
somewhat like this:
Could someone show me some skeleton JSTL or Struts-el code?
I would appreciate it very much,

Re: Loosing request attributes
You shouldn't have to do anything (in general, you rarely need to implement reset) special for this. Struts does this for you. The user submits the form. The form bean is populated with the user's input. Validation starts on the form bean. Validation fails. Struts forwards back to the input page, and the struts tags render all the values that the user had input using the populated form bean. Could you describe in more detail which types of form values seem to be "missing" and which ones are intact? Is there a pattern to it?

Re: Accessing bean properties problem
Janne Mattila wrote: You seem to like parsing HttpServletRequests manually, so why don't you skip Struts altogether and parse all request parameters manually? I bet it would be "clear, extensible, light, fast, loosely coupled solution". Hell, who needs ActionForms after all? They make your solution tightly coupled to Struts! The forms are meant to mine values. They are not meant to supplant business logic. The question is not about "manual" parsing. The question is when and how to parse. Parsing is parsing -- is "manual" of necessity. There is a difference between "manual" and "hard coding". ActionForms are not tightly coupled to Struts. They are Struts. I for one am a great advocate of Struts and believe in fact that in the end it will be preferred to JSF by a long shot. Still, loose coupling is a primary goal of Struts, not the opposite. I am not sure why you prefer your solution. I cannot see a single advantage in practice to it. But, as I said, c'est la vie!

RE: Caching Framework
Code as follows
Caching class
package com.mypackage.Cache
mport org.apache.struts.action.PlugIn;
import org.apache.struts.config.ModuleConfig;
import org.apache.struts.action.ActionServlet;
public class Cacheimplements PlugIn
{
private static Cacheinstance = null;
private ModuleConfig module = null;
private ActionServlet action = null;
public Cache()
{
if (instance == null)
instance = this;
}
public static Cache getInstance()
{
if (instance == null)
instance = new Cache();
return instance;
}
public void init(ActionServlet action, ModuleConfig module)
{
this.action = action;
this.module = module;
put your code in here to fire off any caching of data
}
public void destroy()
{
instance = null;
action = null;
module = null;
any cleanup code.
}
Add the following into your Struts-config.xml file
Parameters can be supplied to the class using the
inclusion between the plug-in statements. You would then have a local
declaration in the Cache class with getter and setter methods to access the
parameter.
Hope this helps.

Ravi, without getting real complicated, I use PlugIns to do this!
Implement org.apache.struts.action.PlugIn. You only need to write two
methods -- init and destroy. In your init method, gather some data store
it as application scope attributes (you get a reference to the
controller Servlet in the init method). Finally, register your PlugIn
with struts-config.xml. When your Struts app initializes, your PlugIn's
init method is invoked. Your JSPs now have easy access to the cached
data, as do your Actions.

Re: Caching Framework

Re: Accessing bean properties problem
I guess, to be more concilliatory, Janne, I could say that if you want
to use your solution, then you could just index item, e.g.
public Id getIndex(Integer id) {
return new Id(intValue());
}
Where the class Id is the following:
public class Id {
private int id;
public Id(Integer x) {
id = x.intValue();
}
public int getId() {
return id;
}
public void setX(Integer x) {
}
public void setY(Integer y) {
}
}
That gets rid of all your classes and gives you the same result.

No mas, Janne! If you think that your serpentine code is superior to the
following:
public class ButtonMiner {
public int getId(HttpServletRequest request) {
String buttonValue = null;
Enumeration enum = request.getParameterNames();
String parameterName = null;
while(enum.hasMoreElements()) {
parameterName = (String)enum.nextElement();
if(parameterName.endsWith(".x")) {
buttonValue =
parameterName.substring(0,parameterName.indexOf('.'));
}
return Integer.parseInt(buttonValue.substring(1));
}
}
which you could get from indexing "_", then go for it! I have no more to
say.

There are two problems, first, your solution does not solve my case. Note
that this is not a simple case of distinguishing whether "accept" or
"nuke" was clicked (for those I would not certainly have used the original
strategy from the wiki page, I agree with over-engineering there) - I want
to get the ID conveniently as well. Please refer to earlier posts for
details. Of course, I can add more parsing code to get also the ID, but
this does not help with the second problem.
Which is: the purpose of Struts is to help me with some tasks, one
important being parsing HttpServletRequest parameters so I do not have to
deal with them manually. This service comes with a price - I have to spend
time to learn the principles of the framework and all the small annoying
quirks and unintuitive details (so far I've ran into quite a few!). If I
have to both learn to cope with Struts and still continue to parse request
parameters manually like I have done so many times before, the deal does
not sound so good to me. The solution you suggest works, is not too
complicated, but it does not integrate as seamlessly with the rest of the
framework and how it is used to handle parameters. Button parameters end
up being an exception to the general rule and I prefer a "pretty"
solution. The solution I described also integrates nicely to the way other
indexed properties are handled on the JSP page.
I don't know, but I am currently satisfied with the solution I am using. I
end up creating one additional class (ImageButtonTracer) and add instance
of it as a field to each form that requires this kind of "indexed
buttons". You would probably create one additional helper class (with a
further developed version of the method you present) and add parameter
name encoding logic to each form that contains such buttons.

This is all "over-engineered", Janne. I used to do something similar,
however. As I menteioned before, I just use the following code to
determine which image was clicked:
String imageClicked = null;
Enumeration enum = request.getParameterNames();
String parameterName = null;
while(enum.hasMoreElements()) {
parameterName = (String)enum.nextElement();
if(parameterName.endsWith(".x")) {
imageClicked =
parameterName.substring(0,parameterName.indexOf('.'));
}
}
return imageClicked;
That's all there is to it. Your button solution is too complicated in
any event. The better button solution involves making only one button
and then nuking that button as soon as you determine what image was
clicked. I just nuked the whole solution, since it is unnecessary.

You could use Providers (http://providers.sourceforge.net) to handle collections of objects, cache them and in addition use these collection to populate select tags, create dependant drop down lists and display labels (descriptions) according to an ID (i.e using tag similar to Struts ) With providers you can create collections with different strategies (fixed, JDBC, filtered, etc) and optionally you could create your own collection factory.

Validating indexed properties
I posted this message to the commons-user list but didn't receive any
feedback. Basically, I am trying to get the indexedListProperty feature
of Validator to allow me to report errors correctly for each property on
a form that fails validation -- the only way I could get it to work was
to change the Validator Field class -- I am trying to find out if there
are any other known work arounds.
===
I have been working with indexedListProperty in Struts 1.2 (using
Validator 1.1.3, I believe). Suppose I have the following validation:
minlength
5
Now, when I validate the form, if the minlength validation fails on one
of the indexed properties, then none of the rest of the partNumber
fields are checked for minlength.
I am using Struts and I was trying to output the error message beside
the property using html:messages -- the result is that the error message
is only generated for the first property that fails.
For what its worth, I did hack a fix -- I changed the
ValidatorResults validate(Map params, Map actions) method in the Field
class [org.apache.commons.validator.Field].
Basically where it had (on line 724):
-
if (!good) {
return allResults;
}
I made it ...
-
if (!good && numberOfFieldsToValidate <= 1) {
return allResults;
}
This worked -- in other words I get all the messages generated for each
field if the field is indexed.
Any opinions on ramifications of making this change or other possible
solutions? I have not messed at all with the client-side javascript so I
am not sure what the behavior is like there.

Re: Accessing bean properties problem
I am well aware of the solution that you suggest and the fact that you think
other solutions are over-engineered - I did indeed try to search for a
solution before creating my own, and noticed the wiki page with the original
over-engineered solution (which I noticed did change just recently).
There are two problems, first, your solution does not solve my case. Note
that this is not a simple case of distinguishing whether "accept" or "nuke"
was clicked (for those I would not certainly have used the original strategy
from the wiki page, I agree with over-engineering there) - I want to get the
ID conveniently as well. Please refer to earlier posts for details. Of
course, I can add more parsing code to get also the ID, but this does not
help with the second problem.
Which is: the purpose of Struts is to help me with some tasks, one important
being parsing HttpServletRequest parameters so I do not have to deal with
them manually. This service comes with a price - I have to spend time to
learn the principles of the framework and all the small annoying quirks and
unintuitive details (so far I've ran into quite a few!). If I have to both
learn to cope with Struts and still continue to parse request parameters
manually like I have done so many times before, the deal does not sound so
good to me. The solution you suggest works, is not too complicated, but it
does not integrate as seamlessly with the rest of the framework and how it
is used to handle parameters. Button parameters end up being an exception to
the general rule and I prefer a "pretty" solution. The solution I described
also integrates nicely to the way other indexed properties are handled on
the JSP page.
I don't know, but I am currently satisfied with the solution I am using. I
end up creating one additional class (ImageButtonTracer) and add instance of
it as a field to each form that requires this kind of "indexed buttons". You
would probably create one additional helper class (with a further developed
version of the method you present) and add parameter name encoding logic to
each form that contains such buttons.

This is all "over-engineered", Janne. I used to do something similar,
however. As I menteioned before, I just use the following code to
determine which image was clicked:
String imageClicked = null;
Enumeration enum = request.getParameterNames();
String parameterName = null;
while(enum.hasMoreElements()) {
parameterName = (String)enum.nextElement();
if(parameterName.endsWith(".x")) {
imageClicked =
parameterName.substring(0,parameterName.indexOf('.'));
}
}
return imageClicked;
That's all there is to it. Your button solution is too complicated in any
event. The better button solution involves making only one button and then
nuking that button as soon as you determine what image was clicked. I just
nuked the whole solution, since it is unnecessary.

ImageButtonTracer can be simplified a bit if one assumes that only one
button can be clicked per request (as is the case) => public
Collection getClickedButtonIndexes() can be changed to public int
getClickedButtonIndex(). This works, and I can use indexed properties
somewhat comfortably.
Any improvements / alternatives are welcome.

I could use some Struts-EL/JSTL tag help, please.
I have a Map with each entry having a String as the key and a bean array

I need two iterations, one nested inside the other.
For the outer iteration, I want to iterate the keySet of the Map. I
don't know what the keys are going to be or how many there will be.
Within that iteration, for each key in the keySet, I need to iterate
over the buckets of the array that is the value for that key.
To make this more clear, let's say I will produce a table of tables,
somewhat like this:
Could someone show me some skeleton JSTL or Struts-el code?
