myValueAdded=my value {0} has been added.
And that you want to print a value at location {0} to be passed from some
jsp or some other file.

Moreover, you can pass upto 5 arguments using arg0, arg1, .., arg4 in the

If you're using Struts 1.2.x and Spring, there's no reason not to use Spring's DelegatingRequestProcessor or DelegatingTilesRequestProcessor -- especially since they set you up to use the IOC (see below). The issue is only if you are using Struts 1.3 (or Struts 1.2.x with the struts-chain library) -- in this case, since you can only have one RequestProcessor, using Spring's will interfere with using the one which uses the Chain-of-Responsibility for handling the request.

This is the Spring feature that I appreciate the most.

Thankyou for your response.
yes, it is displaying in correct form in the browser.
I want to delete the selected values from the original list.
In the Dispatch Action I am checking the selectedList which are
String values with the originallist and doing string comparision to
check if they match and trying to delete them from original list.
but when trying to compare the values as they are different it's not
deleting/removing them from the original list according to the logic
I wrote in delete method.
How would you advice me to proceed on this? Thanks.
below is the code in the jsp.
display:table name=${Form.map.runs} id=mgrRuns
requestURI=PrepareAction.do defaultsort=7 defaultorder=descending
pagesize=6
display:column titleKey=lbl.runname sortable=true

I tried to use LabelValueBean in the multibox. Still it's the same. How
to fix this?
As long as the values are fine in the Action.execute method's ActionForm
parameter, you should be fine. When you use special characters like the
single-quote in values, struts escapes them before sending them to the web
browser (try viewing the HTML source in your browser), and the browser
decodes them when rendering the form. Then when the browser sends them
back, it encodes the values the same way. Struts gets these values and
translates them back into the original form before putting them in your
form bean. I would suggest a couple of things to check:
- Has Struts populated your form bean before you tried viewing the values,
or are you looking at the unencoded values in the DispatchAction class?
- Make sure you're using struts to output the values, and not scriptlets,
which don't encode the values properly.

I don't see where you've told the framework to use your custom
ActionMapping class.
I haven't done this, but from the DTD [1] it looks like you can either set
action-mappings type=...
or
action className=...
depending on whether it applies to just one action or all of them.

RE: message resources
Internally the DynaForm (i.e. DynaBean) uses a Map to store the
properties. This is what allows it to provide dynamic properties and
save you from writing ActionForm subclasses.
When you reference myDynaForm with a JSP Expression Language (EL)
expression like ${myDynaForm.description} reflection is used to call a
getter method (in this case getDescription() on the instance
(myDynaForm).
So... ${myDynaForm.description} is equivalent to
myDynaForm.getDescription()
The DynaForm class does not have this method. It does however have a
method public Map getMap() which returns the Map used to store your
properties. So, by putting ${myDynaForm.map.description} the equivalent
is myDynaForm.getMap().get(description) which will return your
property.
When using the struts bean tags such as bean write the tags are aware of
the DynaBean, and therefore know that they need to get the underlying
Map, then call get(String) using the supplied property.
Make sense?

[Tiles] Embedding tiles inside of tiles
I am new to using tiles and I have a couple of questions. I have written a page layout and I have it coming up but there are a couple of questions that I have. First, my header.jsp has a section where the graphic changes depend on what page is begin displayed. I can't seem to figure out the correct way to implement this. Also do I need an html/jsp page to display this image change or can I just point to the gif file? TIA, Susan == Susan G.

I can't seem to figure out the correct way to implement this. The short answer is to use Tile attributes. The longer answer is that attributes don't always work the way you might think. One of the weaknesses of Tiles is that there's no good way to pass data from one tile to another. Attributes are better suited for static parameter substitution. For example suppose you have Tile A that defines some attributes and Tile B that extends Tile A and overrides some attributes as follows: definition name=tileA path=/layout.jsp put name=headerGraphic value=image1.gif/ put name=someOtherThing value=.../ /definitioin definition name=tileB extends=tileA put name=headerGraphic value=image2.gif/ /definition As long as your layout is completely defined in one JSP page this will all work. It breaks down if your layout has separate pages for header, footer, etc. See below: definition name=tileA path=/layout.jsp put name=header value=/header1.jsp/ put name=headerGraphic value=image1.gif/ put name=someOtherThing value=.../ /definitioin definition name=tileB extends=tileA put name=header value=header2.jsp/ put name=headerGraphic value=image2.gif/ /definition Above you want to define your header differently for two layouts and you want to pass different images in. This won't work because the headerGraphic attribute will not be passed along to the header page unless you do it manually from the page where it is inserted. There's a couple ways to hack this. One is described in another thread: http://mail-archives.apache.org/mod_mbox/struts-user/200605.mbox/% [EMAIL PROTECTED] The other would be, as you indicated in the subject, to embed a tile within a tile: definition name=tileA path=/layout.jsp put name=header value=headerTile1/ put name=someOtherThing value=.../ /definitioin definition name=tileB extends=tileA put name=header value=headerTile2/ /definitioin definitiion name=headerTile1 path=/header.jsp put name=headerGraphic value=image1.jpg/ /definition definitiion name=headerTile2 path=/header.jsp put name=headerGraphic value=image2.jpg/ /definition I haven't tried this, but I don't think it works out of the box. In layout.jsp when you insert the header tile, you'll have to do some magic I think to resolve the name to a tile definition. This should be better supported and hopefully will eventually. Also do I need an html/jsp page to display this image change or can I just point to the gif file? If I understand you correctly I think you should be able to just point to the image file.

The image changes depending on the page that is being displayed. Ideally I

definition name=student.header path=/secure/header.jsp

definition name=student.layout path=/secure/layout.jsp

put name=body value=/secure/student_menu.jsp/
put name=footer value=/secure/footer.jsp/

/tiles-definitions
I want the student.header to be displayed in the student.layout.
You can do something like:
definition name=student.layout path=/secure/layout.jsp
put name=title value=Struts Test/
put name=header value=student.header type=definition /
put name=menu value=/secure/student_menu.jsp/
put name=body value=/secure/student_menu.jsp/
put name=footer value=/secure/footer.jsp/
/definition
Inside the
student.header the description changes depending on the page that is being
displayed.
Do you mean that there are definitions similar to student.layout but
that changes only, say, the body section?
If this is your case you have to extend both student.header and
student.layout
definition name=student.header.abc extends=student.header
put name=description
value=/images/student_pg_header/course_details_abc.html/
/definition
definition name=student.layout.abc extends=student.layout
put name=header value=student.header.abc type=definition /
/definition
Speaking of simple pictures you can do it with some JSP code.
definition name=student.layout.abc extends=student.layout
put name=picture value=/picture/mypicture.gif /
/definition
In your layout page (I think it is /secure/layout.jsp) put:
tiles:importAttribute name=picture scope=page /
html:img page=${picture} /
(If you are using an older Tomcat probably you have to use html-el:img tag)
I hope I got the point.

ActionForm and EJB
Hi, I read few articles on struts. They recommend not to send action form class to EJBs as data holders. They recommend we should use general classes for holding data to decople web tier with EJBs. What they say must be correct but I still have few doubts (Maybe b'cause I am not experienced). Don't we have to modify two classes, if we use both ActionForms and normal java classes to store data.For example we will have modify two classes to add a new attribute, remove attribute etc. Please help me to understand this more clearly.

Re: ActionForm and EJB
Hi Chamal, The recommendation of not passing ActionForms to your business classes stems from two thoughts... First, by passing an ActionForm, you tie your business clases to Struts. Should you want to change to another framework later, your business classes should be unaffected, therefore, passing POJOs to them is a better idea. This also makes unit testing them a little easier since you don't have to manually construct an ActionForm during the test (this isn't such a big deal with ActionForm, but imagine if it for some reason had a reference to an HttpRequest object, then it would be more of a hassle). Second, an ActionForm is, usually, used to repopulate an HTML form on a page when an error occurs, or when a page is initially shown. Since HTML forms only deal in Strings, another recommendation you frequently hear is to only have Strings in your ActionForms. For example, if you have a textbox in your HTML form for a user to enter a date, having a real Date field in the ActionForm can lead to problems because of the conversions that have to take place back and forth (and if I remember correctly, no conversion is done when redisplaying the HTML form anyway, so you'll get the default toString() of the Date object, which is almost certainly not what you want). If you instead make it a String field, the only conversion is when you ultimately need to pass it to the business layer, in which case you have more full control over it. So, since you probably want to be dealing with real Java data types in your business classes, but an ActionForm was designed to deal with HTML forms and therefore only Strings, trying to make an ActionForm serve both purposes can lead to problems, so its easier to just avoid the situation altogether.

RE: response.sendRedirect() doesn't work!
Why not avoid this problem since you are using a tile and simply add a meta refresh at the top? That way you know the page should change and you will have no problem with how Tiles handles output. Personally, I think putting a response.sendRedirect() in a jsp is the wrong place. I try to keep redirect to a blank page or a new Forward(...) with redirect=true in the action an its outcome.

On the other hand, the whole idea of Struts/Commons Validator sucks big time, because database already has all necessary validations, domains, triggers, etc. Since most apps use database anyway, input data should either be validated directly by a database or by DAO; DAO should pull metadata from database to build validation/conversion rules. Seems that Ruby on Rails is closer to this approach, while most other frameworks do the same job twice or even three times.

That's just a recipe for disaster in terms of scalability. Even if you ask the DAO to do it, and even if all the rules are in the DAO and the databse doesn't have to get involved, it's still going down too far into the application. I grant you that some level of validation still generally should happen there, as well as at the database, but in general you want to catch any sort of validation error as soon as you can, whether that means Javascript on the client for simple things or in the database for more complex things (i.e., referential integrity). No, you want as much validation to occur as close to the source of the problem as possible. I agree with you that doing it 2 or 3 times isn't good, and there is probably room for improvement in this regard, but I definitely would not let it fall to the database as a rule. Also, to assume that everyone has all sorts of triggers and domains and such on their databases is, in my experience, a fallacy. I've seen numerous databases that have nothing more than required fields and referential intergrity defined, and that's it. Any data coming in is assumed to otherwise have already been validated. Some people are downright averse to doing more in the database for various reasons. Michael. Frank - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Digester Error while reading struts config file
The concrete SAXParserFactory implementation to use is determined as follows: 1. Use the javax.xml.parsers.SAXParserFactory system property if it is set. (with -Djavax.xml.parsers.SAXParserFactory=my.factory.impl for example) 2. If JRE/lib/jaxp.properties exists and has a javax.xml.parsers.SAXParserFactory use that 3. Use a JAR file service provider to look for a file called META-INF/services/javax.xml.parsers.SAXParserFactory in any jar file on the CLASSPATH I'm thinking whatever jar file has com.bluecast.xml.JAXPSAXParserFactory also has a javax.xml.parsers.SAXParserFactory in the META-INF.

Re: response.sendRedirect() doesn't work!
Thank David for your reply. Actually, I've known that's not right to do it, in the jsp file, but I've have no choice in this situation. Because this is the final page in a wizard-like web application. Normally, the user stop at the final page, but in some case, the user want to redo the wizard again, and they don't want to stop at the final page, just finish the current wizard and start a new one. Any suggestion would be appreciated. Thank you. David Friedman wrote: Why not avoid this problem since you are using a tile and simply add a meta refresh at the top?

Ideally, every such requirement should be stated exactly once. It's also important to recognize that there's more than one kind of validation here ... the most important distinction being presentation (is the date entered by the user syntactically correct for the locale that the user is interacting with or is this a correctly formatted credit card number) versus business rules (is the invoice date after the customer's account-open date or is this credit card number and expiration date actually valid). Because the database will have date-oriented data already converted to a DATE data type, it doesn't really seem appropriate to specify the presentation style restrictions there (most likely it'd be the same stuff for every single DATE in the entire schema). You've also got to deal with interesting complexities such as fields that are required in some contexts and not others, so you probably want some mechanism to deal with exceptions or overrides of the embedded rules. As to where/how to specify validation rules, using annotations for this (at a couple of different levels) looks like an interesting possibility -- indeed, it was one of the topics that several of the Struts committers who got together at JavaOne this year talked about briefly. One could envision a situation where business logic validations were encoded as annotations on the POJOs representing your persistence tier (JPA entity classes, Hibernate based persistent classes, whatever), while presentation tier validations were encoded on whatever things your presentation framework uses to store the intermediate values (properties on an SAF1 ActionForm, or an SAF2/WW action, or on JSF backing bean, for example). Ideally, your presentation framework would also be able to reach through to the business rule validations of the persistent objects your input forms are bound to, so it could perform whatever business rule validations it was able to on the client side (again, in a webapp world, perhaps by having your input field widgets to AJAX callbacks to the server where necessary). Indeed, this whole concept is relevant beyond just web frameworks ... it would make sense in the long term to have a JSR that standardized a set of validation annotations everyone could share, while giving various frameworks the freedom to implement the semantics of doing the validation in whatever fashion best fits the particular technologies that framework uses.

Re: multibox not works when all checkboxes are unselected!
starki78 wrote:
Hi!
I've a large problem with html:multibox.
I've tree checkboxes. When I choose
one or two or three it arrives correct
at the next action!
Only then all checkboxes are deselected
it remembers the state of the checkboxes that was
selected before! The state of the form is session in struts-config.
Can you help me with this problem??
I really don't have an idea how to solve it!
As Adam J. mentioned, it sounds like you're using a session-scoped
bean. Try overriding (if you haven't already) the reset() method of
your form bean and resetting the property:
public void reset( ActionMapping mapping, HttpServletRequest request )
{
this.values = new String[0];
}
If you're _not_ using a session bean (and are using a request-scoped one
instead), you'll _still_ want to do the above. Using this way in both
cases, values from the previous request are discarded. If the web
browser doesn't send any checkbox values over (because none are
checked), then this.values will be an empty array, which corresponds to
the very state of the submitted form's checkboxes (ie: none are checked).
The array of values in your formbean for an html:multibox are a list of
values of checked checkboxes. So...
1. Form bean looks like this:
this.values = { value1, value3, value5 };
2. Displayed form looks like this:
html:multibox property=valuesvalue1/html:multibox 1
html:multibox property=valuesvalue2/html:multibox 2
html:multibox property=valuesvalue3/html:multibox 3
html:multibox property=valuesvalue4/html:multibox 4
html:multibox property=valuesvalue5/html:multibox 5
3. HTML sent to browser looks like this:
input type=checkbox name=values value=value1 checked 1
input type=checkbox name=values value=value1 2
input type=checkbox name=values value=value1 checked 3
input type=checkbox name=values value=value1 4
input type=checkbox name=values value=value1 checked 5
4. User unchecks ALL checkboxes, and submits the form.
5. Struts calls reset() on your form
- Your reset() method sets this.values = new String[0]
6. Struts populates your form, and _doesn't touch values_, because
nothing is checked, so values remains an empty array.
Sound good?

This is of course true... interestingly, I recently did a sample app for some folks at work to demonstrate using Commons Validator via AJAX calls. In the demo, there was a textbox for an account number entry. The example verifies that the account exists on a mainframe system, so I had a custom rule that did the call to the mainframe and all that. This was done via an AJAX call in response to the onBlur of the field. It's interesting because I also demonstrated how the regular Struts app still worked with exactly the same validation rules, and it also showed that you can indeed code business rules in Commons Validator, and of course it showed how you can essentially do an event-based validation from the client, all using the same set of rules and code.

Still, EJBs as they are defined now, do not automatically pull and use database metadata (or do they? I should check out EJB 3.0 spec). So I will be able to use EJBs as backing beans. BFD. Unless I use several databases or design a clustered system, I am not tempted to use EJBs at all. If EJB penetrated deeper in database metadata, then I would have a better incentive to use them (again, have to check the spec. Maybe it already does what I want).

(hey, you were the last Ant vs. Maven holdout, I was happy I wasn't the only one... you left me man!! LOL) That being said, XML configuration files are going out of fashion, at least among the developers who speak out a lot :-). Yeah, I noticed that. :) I'll be there in 5 years or so :) I personally think this is the case because there are some *bad* XML config files around. I think when done right they are still preferable in most cases. However... Here's my two cents on when I like to use annotations, and when I don't. * Annotations are a good idea when the configuration concept is directly related to how you code your source. Examples include beans used in a webapp (it really matters whether you're going to store it in request scope or session scope or application scope), transactional settings on an EJB, and so on. Storing the actual annotation in the source code reduces the chances that some sysadmin installing your application might accidentally or inadvertently change the scope setting, without understanding that they just broke your code. Definitely fair poins... and I have to admit, looking at EJB3 as an example, I in fact *love* annotations! EJB's (pre-EJB3) are probably the best example IMO of where config files can go wrong. * Annotations are not a good idea when the configuration concept should not be a concern of the person actually writing the code. In webapps, for example, I don't believe in configuring page navigation rules (Struts forwards, JSF navigation rules and cases, etc) directly into the action methods. The actions should describe what happened, not where to go next -- and this is something I personally don't care for, even at the code level, the way that WW2 does Results (or Spring MVC does ModelAndView) that combine the two concerns together. But that's a separate issue from whether the encoding should be with annotations or not :-). I agree with you here too. I remember 5 years or so ago before I started using Struts, we built our own framework here, and one of the really nice things about it is that all the navigations rules were in a database... we could literally change the flow of the application on the fly (a few exceptions, as you might expect, but generally true). Separating navigation rules and such from the code I agree is probably not the right use for annotations. Good thoughts... I think we agree here almost entirely :) I like your differentiation too... I think when I said I wasn't sold on annotations yet I may have been subconsciously thinking of the things we both think may not be the best use for them. Especially given EJB3, where I do really see where they make life better, maybe I'm a little more on the bandwagon than I thought already! :-) Craig Frank - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I think that's more or less what Craig was saying as well; there are some things that simply don't belong in annotations; for me that's really high on the list. I'd also rather tweak a config file to define a service implementation than dink in the source code, although that one is less problematic for me. If it doesn't change the way I'd write the code then for me it's better somewhere else than the code. Like Frank I've also done a lot with putting things into a DB that can alter (sometimes radically!) the way an application works without having to restart anything (DI configured from a DB can be WONDERFUL, especially if you don't have access to the config files... and can store implementations in the DB... dangerous, but very handy).

Yes, but that's only one aspect of it... scalability is also a factor, as is number of breakage point, as is cost, because to overcome the first two you have to spend more. Not to mention complexity, and the need to hire people with more database expertise. This should not (ideally) bother an application developer. A framework should care about that. As far as who provides the actual code, I agree. But certainly the application developer has to worry about how the architecture affects performance, scalability, stability, etc, whether they write the code themselves or not. If database has already defined the rules, they should be used. But can you even code all the complex business logic in the database that you might require? I suppose you could write stored procs in Java... I wonder how much more difficult that would prove than business classes on the app server? (I've never done it, so I don't know) But I don't want to repeat the same rules again and again. This part we definitely agree on. But a Craig pointed out, there are different kinds of validation rules, and the repetition is limited somewhat by the domains being different. What I mean is, you want to create a new Student record in the database... you may want to validate that the first name, last name and teacher's name are entered. You do that in the presentation (whether on the client or server, doesn't matter) because they aren't business rules per se. You can do this and not duplicate the code (use Commons Validator, can be called via AJAX if you want, I've done it). Now, when you save the record, the record is to be tied to the teacher's record. So, now you have a referential integrity check: does the entered teacher's name exist? This isn't a check you would generally do in the presentation layer anyway, they are really two separate concerns, and appropriate in different places, so there's no real duplication there. To summarize my thinking, I think there's really three different types of validation: presentation, business and data model. The presentation-type validations are where you many times see duplication... i.e., Javascript to see if a first name is filled in, then that same check done on the server, since that double-checking is of course a best practice. I think there are ways to avoid that though: doing those validations with Commons Validator and calling it via AJAX, and still letting those SAME RULES fire when the final form is submitted, does the trick (or letting Struts generate the client-side validation code, if you want to avoid the AJAX call). For business rules, these are the is the entered dollar amount greater than the max value for this client? sort of validations. I find these to be more appropriate on the app server, NOT in the database, for a variety of reasons (all the reasons I mentioned earlier, plus the fact that many times you find that you want a chain of such validations, which I think is easier to build outside the database using a real CoR implementation). Then you have the database validations, things like referential integrity. In other words, only do validations here that couldn't be done previously without hitting the database. This also simplifies the data tier because it tends to reduce the number of stored procs (read: code in the database) that has to be written... most of this can be done with triggers and such, which aren't really code, not as much as stored procs anyway. In other words, I view the database as a database and not an app server, generally-speaking. Unless I use several databases or design a clustered system, I am not tempted to use EJBs at all. I've historically HATED EJBs for various reasons... I think EJB3 finally begins to get them right, and I think you may be surprised how and where you want to use them all of a sudden. Another discussion for another day though :) Check out Stripes, great stuff. Yes, it's on my take a look at that list already :) Frank - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Re: Extending Struts with Spring

hi. I have two different pages that call the same action. I'm using validate=true in the action mapping. Can I specify the 'input' attribute dynamically (or set it somewhere while the action is being called, before validation?). never tried, but ... your action's execute method gives you an ActionMapping object which can call setInput(String input). you have to set validate=false in order to give control to the action before validation starts. you can then manually call form.validate(mapping, request) (+ save errors into request, + return inputForward ). hth, ralf - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Can I specify the 'input' attribute dynamically (or set it somewhere while the action is being called, before validation?). You cannot change config information that has been defined in struts-config.xml file. If you try, you will likely get The configuration is frozen exception. You may want to try using wildcards [1], but it looks that wildcards are not the answer to your question. I suggest to look at your issue from another perspective. Do you really need the functionality you are asking for? First, a small clarification. There is no input page for an action, input attribute is poorly named, it should be called error or errorTarget, because Struts forwards to that location if input data does not validate. Your request is always sent to action/actionform. It appears to me that you have two different HTML forms that are submitted to one action. After many years of using Struts this page-oriented approach seems convoluted and inflexible to me. If these forms are different views of one web resource, they should be rendered by one action, and a proper page is chosen depending on resource state. If these forms are views of different resources, then they should be served by different action classes belonging to different web resources, that is, you simply should not submit to one action class from views that represent different web resources. So, to display the first form you call FirstAction and tell it to render itself. It shows the form, you fill it out, submit, in case of error it redisplays the form. Do display the second form you call SecondAction and tell it to render itself. It shows the form, you fill it out, submit, in case of error it redisplays the form. :-) This is it, all you need is two actions, not two input attributes. If you have time, the DataEntryForm page [2] explains my opinion on that matter.

Re: [shale] Problems after updating to MyFaces 1.1.3
From: Richard Wallace [EMAIL PROTECTED] Hey all, I'm having a problem with clay after updating to MyFaces 1.1.3 and Tomahawk 1.1.3. I'm getting a couple of these when the webapp is deployed: 2006-06-08 10:02:55,174 2621 ERROR [http-8080-Processor24] org.apache.shale.clay.config.beans.ComponentConfigBean (ComponentConfigBean.java:235) - java.net.MalformedURLException: Path does not start with a / character This one kind of looks like it might be an issue with tokenizing the COMMON_CONFIG_FILES value list. I think that it might not be ignoring all the whitespace between config files. That might explain the exception if it's on a path of . Try putting the list of files on the same line. If that works, please create a JIRA ticket on it. The configuration in the web.xml is !-- Clay Common Configuration Resources -- context-param param nameorg.apache.shale.clay.COMMON_CONFIG_FILES/param-name param-value /WEB-INF/clay-common-config.xml, /WEB-INF/clay-institution-config.xml, /WEB-INF/clay-common-symbols.xml, /WEB-INF/clay-institution-symbols.xml, /WEB-INF/clay-tomahawk-config.xml /param-value /context-param I'm using the shale-1.0.3-SNAPSHOT from the maven repo at http://svn.apache.org/maven-snapshot-repository. The strange thing is that the app seems to start up normally otherwise. Any ideas what could be going on here? I'm also having a problem whenever I submit a form that for some reason it doesn't seem to be doing navigation properly, and strangest of all, the page that is rendered gets rendered three times, one right after the other. Has anyone else seen this odd behaviour? I'm not sure about the weird rendering problem but it might be a result of not loading all the clay resources. Since this happens in a context listener, exceptions can only be logged. It doesn't top the loading of the app. Thanks, Rich - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: hotkeys
Hi Marcus, Take a look at the accessKey attribute, I think that's what you want... however, I don't believe it is possible to assign function keys, I think you only have letters and numbers, and maybe punctuation marks. You could do what you want via scripting though, where I believe you can capture function keys. Try setting up a key handler for the document itself, and just call focus() on the element you want to receive focus when the appropriate key is pressed.

Can I use swings instead of jsp as view in struts Regards Pradhap
Re: kindly help please
Hi Pradhap, Yes, you can. However, your JSPs will in all probability NOT be rendering markup for display to the user... they will probably generate some sort of data structure that your Swing client will use to update the view. Maybe XML for example. Your Swing app just makes HTTP requests to the app on the server as usual. I know this because about 3 years ago I was asked to do this... the project didn't go beyond proof-of-concept, but it was working just fine before it was aborted. Now, keep in mind that when you use JSPs, assuming you use Struts tags, you'll be giving that stuff up, or more precisely, you'll have to code it all yourself... if input validation fails for instance, you'll have to deal with redisplaying the entered values (if they were ever not visible that is).
