[OT] support for *.do files
Since this is rather OT, I have marked the subject as such. Rather than use mod_jk, I have been in the habit of using mod_proxy and have httpd.conf as follows: It works fine for me - but I'm unsure - are there performance disadvantages with mod_proxy?

That's why you have to specify a port - Tomcat, which is running on the port you specify, does know about the web app. You've got to setup a mapping in your Apache config (httpd.conf, I think) that tells apache, for a given path, to pass control to Tomcat.

Hi,
You can clone the Category object implementanting the

correct the code in the following way:

iterator.hasNext(); )
13. {

A table on a form from a List of Lists
Hi,
i have been trying to create a table on my form from a single property in my
actionForm. the property is a List (actually an ArrayList) containg the rows of
the table, each element (i.e row on the table) is represented by a List of
Strings representing the fields of the list. i can code my JSP page to display
the contents of the proprety in a table but i cant get it to set the values of
the property from the page on submit. all the efforts has failed, i my latest
effort, i coded the property as property[row][col] but i get an error that dia
is no getter method for property[0][0]. i wrote the access methods like
String getProperty(int row, int col){
return (String)((List)property.get(row)).get(col);
}
it did not work, any ideas will be apreciated.
Re: Simple way to configure an action?
OK, I think i understand what you are trying to do. You could override the constructor of your action to read in a properties file. If you have multiple actions, you could make it a base class that uses some common naming convention, that may simplify things.

error and warning messages
Hi I have the requirement to perform server side validation on a form, no probs. The problem is that i have a set of error rules and a set of warning rules. There is no problem defining the errors in my validation.xml and returning the user to the page to correct them, however at some point probably when all error messages have been validated i need to show warning messages. For example value X is outside of the normal range do you want to continue? If not i want the user to be able to change their value, however this then means i need to do the error checking again incase the user has changed there warning value to an error value!! I thought of the idea of having error rules in my validation.xml and then dynamically validating the warning rules progmatically in my action (not sure if this is the best method though). Has anyone come across a solution or able to think of a better method of implementing this functionality.

This is pretty basic Java. Java is pass by reference, so there is
only one copy of the ICCategory. If you want multiple copies your

Re: Simple way to 'configure' an action?
Another possible approach is to create a DefaultValues class, something along
these lines:
public class DefaultValues {
private HashMap defaultValues;
{
setDefaultValues();
}
public static HashMap getDefaultValues() {
return defaultValues;
}
private static void setDefaultValues() {
// Insert code to read in property file here
// and store them in defaultValues
}
public static void resetDefaultValues() {
setDefaultValues();
}
}
The benefit I think is that it keeps your default values independant of the
Actions. Having the resetDefaultValues() method gives you a way to
reinitialize the values without taking your app down (i.e., maybe on an Admin
page you provide a Reset Default Values button that results in that method
being called). By putting the property file read in the Action constructor,
I'm not sure you'd be able to do this since Struts creates the one instance of
your Action and gets a reference to it per request. I suppose you could do the
above in an Action essentially and call setDefaultValues() from the constructor
rather than a static initializer, but then you get into the question of whether
that's thread-safe, since an Action has to be.
In either case, just mentioning another possibility. :)

Re: A table on a form from a List of Lists
Take a look at the nested tags.
In your case, your code may end up looking like:
nested:form action=/myAction
table
nested:iterate property=listOfRows
tr
nested:iterate property=listOfFields
td
nested:text property=myField
/td
/nested:iterate
tr/

Re: Where to send !isTokenValid(request)
Thanks for your response. It was helpful since it brought up some other instances that I hadn't really thought of, such as allowing a double submit for certain actions. Here is the flow we have for this application. 1. User searches for a profile 2. List of matching profiles is displayed 3. User clicks the EDIT link for the profile they want to update 4. Profile is displayed with a TOKEN embedded in a hidden form field 5. User hits Submit to update changes (possibly hitting it twice). 6. If isValidToken == TRUE, call resetToken(request) and the Action will Forward to: a) A confim page using redirect on SUCCESS b) Back to the form page with error msgs on FAILURE So where do I go if isValidToken != TRUE? Personally I wouldn't want to check for double submit if the action is going to do an Update similar to your case (Profile Update) for the simple reason that the form could have been changed between two submits (If the Update is taking 5 secs, let's say (for whatever reason), the user has enough time to change his profile and do another submit before the previous submit is completed. In this case, it's better to save the latest changes by the user) The truth is, the section that's really causing us problems is our enrollment section (adding a user). The problem is really a transactional issue. User fills out a form, submits it, which is then supposed to take that info, create a profile for our website and and then submit that info to a 3rd party which will create a linked account on their side. The problem is caused when the user submit twice. If we send the same request to our 3rd party, their web service throws an exception. We have now idea what the result of the first request was. So in your opinion, in a case like this, is it best to just take them to an error page? If so, do you take them to a blank error page or take them back to the form they filled out with the error on top? Here's what I'd like to do. I'd like to basically store in the session the Token, the requested ActionMapping and the UID of the object being handled (in this case a profile_ID). Then if the isValidToken returns false, look in the session for the last *successful* token that matched the ActionMapping and profile_ID for this request and send them to the same result page. Does that make sense? I wouldn't want to store the ActionMapping in the session because I get the same ActionMapping to the execute method. Well one pitfall I think will potentially happen is this [ User successfully updates a profile with profile id : 150 (no double submit) and you show him a success page saying profile with profile id 150 is successfully updated Next thing the user does, being in the same session, is that he tries to update profile with profile id 151 (but clicking multiple times). Now your application will show the user profile with profile id 150 is successfully updated instead of showing profile with profile id 151 is successfully updated (Also with the potential of ignoring the user's latest changes) Why wouldn't the message be updated to show 151? Wouldn't the first request on the double click have over written the 150? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Simple way to configure an action?
Eddie Bush's solution is the right one. The ActionMapping is specifically intended for the purpose you have in mind, and is available every time an Action's execute method is called. Even if the Action will not be called from different action mappings, it will always have one action mapping. What's the problem with reading the values from the ActionMapping when the action executes? I'm generally believing that the original motivation for Struts to work this way (pool actions instead of creating one per request) has proven not to be all that useful, and some of the benefits of being able to treat an Action as a request-scoped instance are part of what people like about frameworks like Webwork. It might be worth investigating whether there actually are meaningful performance implications to instantiating an Action upon every request, although a bug in the Struts Chain code (fixed only a month or two ago) was causing this very situation, and it didn't have a noticeable impact on a production application I had built upon it. Don Brown's Struts-Spring project had a proxy action which created a new Action instance for each request based on a Spring configuration. The project is discontinued in favor of equivalent behavior in the Spring core, but you can get the details on that (and a link to currently active substitutes) at http://struts.sourceforge.net/struts-spring/index.html Joe At 8:02 AM + 1/24/05, Fredrik Jonson wrote: On 2005-01-24, Larry Meadors [EMAIL PROTECTED] wrote: Maybe we are approaching this from the wrong direction. what is the problem you are trying to solve?

RE: max file size - validator - javascript
Its to do with the browser security manager, in i.e. anyway, you can't script the File field in any fashion with regards to file location, size etc.. You'll need to write an applet and do some io to do the checking if you need to validate client side. In Netscape their are ways round this with special javascript functions that have access to disk client side. Devedge.com is where I was reading this. However in a public domain the lowest common denominator is what your looking for. The problem with the applet is if you have more fields than just a file field to submit then your going to want to have the applet make the actual http post. Once it validates your file field it can call a javascript function which can then pass the rest of the form element values into the applet for posting to your server. You won't be able to do the reverse, again due to the security manager. -Original Message- From: Joe Germuska [mailto:[EMAIL PROTECTED] Sent: 24 January 2005 15:22 To: Nathan Coast; Struts Users Mailing List Subject: Re: max file size - validator - javascript At 3:01 PM +0800 1/24/05, Nathan Coast wrote: Hi, Does the validator support max file size for an uploaded file?

Re: How to get the input action path?
There will be a request attribute under the name org.apache.struts.action.mapping.instance. Call getPath() on that (after casting to an ActionMapping). I'd take a look around to see if there's a static method somewhere that gets this for you rather than coding the name of the attribute because should it ever change in a future Struts version and you upgrade, your code would break. But, that should work for you now. -- Frank W.

True enough, but at some point you have to trust those under you. So long as
you make this information known, you have to trust that they will use it.
If they remember, don't get in a hurry or otherwise do something human.
Why not do something like
private static blah execute(blah) throws Exception {
criticalSetupstuff;
continueExecute(blah);
}
protected blah continueExecute(bladh) throws Exception {
whatever the execute should do.
}
That way you can gurantee that anyone inheriting from this action will
get the crttical setup stuff.

You can use a custom RequestProcessor instead of a common Action method
to make sure your Action writers don't forget to call the setup
method. Another trick is to write a base Action class with a final
execute method so Action writers can't skip steps:
public class MyBaseAction extends Action {
public final ActionForward execute(form, mapping, request, response) {
initializeRequestAttributes(form, mapping, request, response);
return realExecute(form, mapping, request, response);
}
protected final void initializeRequestAttributes(form, mapping,
request, response) {
request.setAttribute(command,mapping.getPath());
}
protected ActionForward realExecute(form,mapping,request,response) {
// this method is what Action developers write
}
}

Re: How to get the input action path?
I thought of something similar too Jim, but my thought was that now they are
coding classes that don't truly adere to the general form of an Action. I
would rather have the basic structure remain the same and just make them have
to remember to call the setup code.
Think of it this way... the more a team veers from standard Struts (or
standard anything for that matter!), the more a new team member has to learn
and comprehend before they can really be effective. In my mind, a single
method call that someone has to remember is better with the idea of swappable
human resources in mind than having to learn and understand a new structure for
an Action (even if it is very simple, as what you show is).
I suppose we could have the best of both worlds if you implement a custom
RequestProcessor that looks for some flag attribute in request that is only set
from the setup code and redirects to some error page if it's not set. That
way, the Actions can remain structured as usual, and if a developer forgets
that setup call, they'll know about it right away.
But then, that starts to feel like babysitting my developers, and I for one
don't do that. I hire those that I have confidence in, and I let them do their
thing based on my architectural blueprints. I trust them to get it right, or
at least quickly and efficiently fix it if they don't! :)

True enough, but at some point you have to trust those under you. So
long as you make this information known, you have to trust that they
will use it.
If they remember, don't get in a hurry or otherwise do something human.
Why not do something like
private static blah execute(blah) throws Exception {
criticalSetupstuff;
continueExecute(blah);
}
protected blah continueExecute(bladh) throws Exception {
whatever the execute should do.
}
That way you can gurantee that anyone inheriting from this action will
get the crttical setup stuff.

I thought of something similar too Jim, but my thought was that now they are
coding classes that don't truly adere to the general form of an Action. I
would rather have the basic structure remain the same and just make them have
to remember to call the setup code.
If you have to revert back to a standard action, just rename the
method call, it shoudl be the exact same format as the original
execute.
Think of it this way... the more a team veers from standard Struts (or
standard anything for that matter!), the more a new team member has to learn
and comprehend before they can really be effective. In my mind, a single
method call that someone has to remember is better with the idea of swappable
human resources in mind than having to learn and understand a new structure
for an Action (even if it is very simple, as what you show is).
Except that a newbie is less likely to remember exceptions like this
action has to call a special method first. If a newbie tries to
inherit from the final execute, he gets an error, goes to investigate
and goes oh.. okay.
I suppose we could have the best of both worlds if you implement a custom
RequestProcessor that looks for some flag attribute in request that is only
set from the setup code and redirects to some error page if it's not set.
That way, the Actions can remain structured as usual, and if a developer
forgets that setup call, they'll know about it right away.
But then, that starts to feel like babysitting my developers, and I for one
don't do that. I hire those that I have confidence in, and I let them do
their thing based on my architectural blueprints. I trust them to get it
right, or at least quickly and efficiently fix it if they don't! :)
I trust them to I just excpect them to be human. In addition the
less extra stuff they have to remember, the fewer mistakes they can
make. If you see code where ti spends most of it's time figuring out
exceptions then it does doing work, you probably immediately think
Time to refactor. Same thing with processes we have to use when
coding. The fewer exceptions I have to think about, the better.
In my suggestion, the programmer can forget about what they have to
call and the langauge takes care of larting them if they forgeet, and
telling them how to fix before they even run a unit test.
As for using a custom request processer, that's further afield from
standard struts then my suggestion. You could use a filter for the
same thing, and not have to worry about what happens when you upgrade
struts.

[OT]Applet question, open in new JVM
Hi I was working on a Applet in which i had some static methods in a class with some applet data, it was working great untill i had to develop another applet which uses these static methods, now the problem is the data is getting mixed when i open both the applets. i want to know if i can open the second applet in new JVM so it will be a different applet JVM, as if the applet is from 2 different web sites = A$HI$H __ Do you Yahoo!?

I had posted earlier concerning this, and haven't gotten any response,
but I think it got lost in all the spirited discussions about

I've done a lot of searching, and AFAICT, I'm trying all the right

I promise I google'd first
I'm trying to use a multiple-select select box, for example:
html:select multiple=true property=bar size=5
html:option value=1One/html:option
html:option value=2Two/html:option
html:option value=3Three/html:option
html:option value=4Four/html:option

And I've tried backing my form bean with String[] AND with an
ArrayList.
When I try to use a String[] as the backing, the form displays, but
when I submit, I get an argument type mismatch:

RE: Select Multiple Issues
I have ActionForm's that contain String array variables like:
private String[] parmTypeCd = null;
With the normal:
public String[] getParmTypeCd() {
return parmTypeCd;
}
public void setParmTypeCd(String parmTypeCd[]) {
this.parmTypeCd = parmTypeCd;
}
My form has:
html:select property=parmTypeCd multiple=true size=3
html:option value=1Value1/html:option
html:option value=2Value2/html:option
...
/html:select
Then, underneath I build my ArrayList to pass to my iBatis query like:
ArrayList parmTypeCds = null;
if(form.getParmTypeCd() != null form.getParmTypeCd().length 0) {
parmTypeCds = new ArrayList();
String typeCds[] = form.getParmTypeCd();
for(int i=0; iform.getParmTypeCd().length; i++) {

}

Re: Select Multiple Issues
It's related to a difference in how the HTTP request parameters are
built. With the indexed properties that you had, the BeanUtils
classes are going to look for parameters whose names include the index.
That is 'bar[1]', 'bar[2]', etc.
HTML:select with multiple=true sends multiple parameters, all with the
name of 'bar'. So, instead of 'bar[1]=1bar[2]=2' the HTTP request will
just be 'bar=1bar=2'. The Java Servlet API exposes these multiple
requests with the same name as a String[], or the first one as a single
String.
The only time the Struts ActionForm framework is going to call an
ActionForm setter 'setBar(int index, String value)' is if the request
includes parameters named as in the first example. It will call the
setter 'setBar(String[] values)' if it sees multiple values for the same
parameter.

Best practice for dynamic Title values using Tiles?
I'm switching back to using Tiles instead of Sitemesh and I remember one issue that I found annoying with Tiles and I'd be curious how you guys handle it. Say I have a form that is going to be reused for both Edit and Add. I want the title attribute to read something like Add Employee or Edit Employee, depending on what I'm doing. It seems silly to have to create multiple definitions in my tiles-definitions that are essentially the same exact definition except that the title has changed (potentially you might want a definition to be used for more than just the two that I mentioned). This also requires that my struts config has to be set up to forward to multiple tiles definitions when its really the same page layout but with a different title and could really just require one definition to use. I've thought of different ways I might want to handle this (ie set a title in request scope before leaving action and have the header.jsp look for this, or maybe use a filter or over-ride RequestProcessor?) I'm curious if others have run into this. Maybe the latest Struts/Tiles has a solution that I have not looked into.

Re: Select Multiple Issues
Well, I understand the way HTTP is working there, it just SEEMS to be that having the additional method (setBar(int, String)) confused BeanUtils or something - because removing those methods (making no other changes) cleared the problem up. w On Mon, 24 Jan 2005 17:15:01 -0500 Jeff Beal [EMAIL PROTECTED] wrote: It's related to a difference in how the HTTP request parameters are built.

The only time the Struts ActionForm framework is going to call an ActionForm setter 'setBar(int index, String value)' is if the request includes parameters named as in the first example. It will call the setter 'setBar(String[] values)' if it sees multiple values for the same parameter. -- Jeff - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Select Multiple Issues
From: Will Stranathan [EMAIL PROTECTED] Well, I understand the way HTTP is working there, it just SEEMS to be that having the additional method (setBar(int, String)) confused BeanUtils or something - because removing those methods (making no other changes) cleared the problem up.

RE: Best practice for dynamic Title values using Tiles?
Rick, Did you consider making your Action a TilesAction so you can put the title into the context however you want? That way, if you do a CRUD methodology, you could do a context.putAttribute(title,new String(Edit)); or Add depending on your Action's CRUD method. Heck, you could also do that to the body attribute and change a JSP inserted into the middle of your template. You could have a definition look like this: definition name=.generic path=/WEB-INF/pages/common.jsp put name=title value=Default Value / put name=body value=/WEB-INF/pages/default-center.jsp / /definition Then, in the extreme, all of your actions could se the title and their own body choice. Viola! One template fits all!

Redirecting to outside the webapp
Hello All, Long time lurker, first time poster. I'm trying integrate our Java Struts webapplication with an existing web app. After logging into the Java site, I want to redirect to outside the webapp, but struts keeps prepending the webapp name. For example. in my struts-config.xml I have the following: action path=/LoginSubmit name=loginForm scope=request validate=false input=/WEB-INF/pages/common/login.jsp type=com.company.frontend.action.LoginAction forward name=success path=/index.pxt redirect=true / forward name=failure path=/WEB-INF/pages/common/login.jsp / /action I want to be sent to http://hostname/index.pxt after the LoginSubmit action has been executed. But we always get sent to http://hostname/webappname/index.pxt which causes a 404. Is there anyway to get out of the webapp either through configuration or through customization?

If you create your own ActionForward, and you redirect with a string that starts with /, the result will still be the same.

Re: LazyValidatorForm incompatible with using dot separated, etc., method indicators
Using nested properties can be an issue with LazyDynaBeans (but it can also be an issue using a POJO Beans or regular DynaBeans). Say you have a property named foo.bar - in order to set this value BeanUtils populate method will try to do the following: * call the get(foo) method to retrieve the foo property * call the set(bar, value) method on the foo object to set the value If the foo property doesn't exist in your LazyDynaBean then it will return null and you get the NestedNullException you're seeing. The usual way to resolve this would be (if you have a Foo class which has a default empty constructor) to define the foo property for your LazyValidatorForm in your struts-config: form-bean name=... type=org.apache.struts.validator.LazyValidatorForm form-property name=foo type=myPackage.Foo/ /form-bean or use a LazyDynaBean for the foo property form-bean name=... type=org.apache.struts.validator.LazyValidatorForm form-property name=foo type=org.apache.commons.beanutils.LazyDynaBean/ /form-bean LazyValidatorForm will try and instantiate the foo property for you. I'm not sure why you're getting the No bean specified error - looks to me like the ActionForm you're passing to BeanUtils populate() is null - check your logs to see if there are errors instantiating the ActionForm.

Re: Where is the Struts 1.2.6 API for taglibs?
Sorry, late to this discussion. One thought from this (and oither) thread - did you upgrade BeanUtils to version 1.7.0? LazyValidatorForm depends on LazyDynaBean which is only in Version 1.7.0 of BeanUtils. What makes me think that is it doesn't seem that LazyValidator form works for you in any way - if it can't find the class then there should be errors logged. Wendy is right (I think) - if its a DynaBean then BeanUtils should ignore any regular properties youve added and just use the DynaBean get/set methods. Rather than extending LazyValidatorForm, you could define these as beans in the struts-config - then LazyValidatorForm should try and instantiate them: form-bean name=... type=org.apache.struts.validator.LazyValidatorForm form-property name=adminFormtype=mypackage.AdminForm/ form-property name=chatFormtype=mypackage.ChatForm/ /form-bean Niall - Original Message - From: Dakota Jack [EMAIL PROTECTED] To: Struts Users Mailing List user@struts.apache.org Sent: Monday, January 24, 2005 6:25 AM Subject: Re: Where is the Struts 1.2.6 API for taglibs?

RE: [OT] Re: Best practice for dynamic Title values using Tiles?
+1 on Erik's request. I sometimes go about things the wrong way. I was thinking I should use SiteMesh to figure out which HTML page to use as the final layout for each virtual host (the SiteMesh decorator I'm going to write will figure that out and make sure it exists) OR use tiles with div's plus a CSS to lay out the locations of the divs. The SiteMesh option will work with older browsers who aren't handy with CSS but the tiles+div+CSS option would be much more modern. I could then use tiles to change the CSS if someone wanted a more printable layout (i.e. hide ads or other un-printer friendly components). This makes me curious about what shortcoming you found in SiteMesh related to your particular project.

Re: Select Multiple Issues
Nope, actually, it is bean-utils that is at fault here (something all struts developers should be accustomed to saying - IMO, bean-utils is the single weakest component in struts). According to the javabeans specification (http://java.sun.com/products/javabeans/docs/spec.html), indexed properties should look like this: 1) void setter(int index, PropertyType value); // indexed setter 2) PropertyType getter(int index); // indexed getter 3) void setter(PropertyType values[]); // array setter 4) PropertyType[] getter(); // array getter But the last time I looked, bean-utils never used the indexed getter/setter methods (#1 or #2) - in fact, it never even called the array setter (#3). Instead, it got a reference to the array by calling method #4, and set the elements in it directly.

Re: Select Multiple Issues
From: Larry Meadors [EMAIL PROTECTED] Nope, actually, it is bean-utils that is at fault here (something all struts developers should be accustomed to saying - IMO, bean-utils is the single weakest component in struts). I stand corrected, it even _says_ (8.3.3) that 'an indexed property might be represented by four accessor methods.' So your code was correct, sorry! Personally, I've never gotten anything but grief from having more than a single pair of methods. Then again... all of my 'bean' experience is with Struts and by extension, BeanUtils. -- Wendy Smoak - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I would check the following things:
* Make sure that the validation plugin is defined
* Make sure that watchForm extends ValidatorForm and not ValidatorActionForm
* Make sure that the validate method calls the super.validate() and
takes the errors into account, if the validate method is overridden
Here is my form action: (it works)
watchActionAdd.do?method=add
Here is the form declaration:
action path=/watchActionAdd

Re: [ANN] Expresso 5.6 Released
Hi friends , Could somebody give some feedback on Expresso 5.6 , if they have used or evaluated the product ... Does it really helps to shift to this framework ..? Has it overcome some problems faced by struts ..? Is it equally flexible as struts where we can modify some source ( Like requestprocessors , action classes , etc..) according to our own needs ?

Re: [OT] Re: Best practice for dynamic Title values using Tiles?
Erik Weber wrote the following on 1/24/2005 10:47 PM: Hello Rick. Happy New Year to you. I'm just curious. Why are you switching? I remember you advocating Sitemesh (I think it was on your site) instead of Tiles at some point. I haven't tried either one yet, but was going to try Sitemesh based largely on your recommendation, The reason I'm switching is that some of the pages we display can possibly be very very large in size (reporting information). SitemMesh has to store the entire response as a String in an object (I think backed as StringBuffer but not positive). So you can see the problem if you potentially have a huge page to display. Locally, I actually crashed my version of Tomcat when trying to render a page since it ran out of memory when trying to buffer such a large page. Tiles doesn't have this problem since it flushes the response out as it goes along. Tiles, although more work to configure, saves me from having to worry about these potential memory problems. -- Rick - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: How to add your own validation + make use of existing validator

In brief: 1) Override validate method, and call super.validate, then provide your validation. 2) Write your own custom validator. 3)Some validations are applications of business rules, and as such may belong in your business layer rather then in the validator framework. for more details please search the list. regards Manisha - Do you Yahoo!?

Re: Best practice for dynamic Title values using Tiles?
Phil Steitz wrote the following on 1/24/2005 7:25 PM:
tiles:put name='title' type=string
logic:equal name=bookForm property=action
scope=request value=Create
bean:message key=book.title.create/
/logic:equal
logic:equal name=bookForm property=action
scope=request value=Update
bean:message key=book.title.update/
/logic:equal
/tiles:put
May not be the best, but keeps display stuff separate.
This would be way to combersome since the title will be displayed in a
reusable header page. The result would be that you'd have to code one
huge long logic construct to decide what to display for the title for
every possible action.
I'm not totally opposed to using the request approach mentioned where I
stuff a title attribute into the request in the Action and can then
display it on the page...
title${title}/title
however, I'm starting to lean towards adding redundant code in the tiles
config. At least all the titles will be in one place. Unfortunately this
also requires me to have unique action forward mappings so that the
correct tiles definition will be called. So I can't just have the
forward go to a default myForm.page for both edit and add. I have to use
edit.form.page and add.form.page simply so that the tiles defintion can
add the correct title even though I'm going to the same JSP.
I'm still torn on which approach to use:)

Re: Best practice for dynamic Title values using Tiles?
I just have a c:out value='state.title'/ and feed the appropriate
value to the request. State is a class as follows:
public class StateContainer
implements Map {
private Map map;
public StateContainer() {
int size = 89;
this.map = Collections.synchronizedMap(new HashMap(size));
}
public void setStateContainerMap(Map map) {
this.map = map; }
public void setProperty(Object key, Object value) { map.put(key,value); }
public MapgetStateContainerMap() {
return map; }
public Object getProperty(Object key) { return map.get(key); }
public StateContainer putState(String key, Object value) {
this.put(key,value);
return this;
}
public void clear() { map.clear(); }
public booleancontainsKey(Object key) { return
map.containsKey(key);}
public booleancontainsValue(Object value) { return
map.containsValue(value); }
public SetentrySet(){ return map.entrySet(); }
public booleanequals(Object object) { return map.equals(object); }
public Object get(Object key) { return map.get(key); }
public inthashCode(){ return map.hashCode(); }
public booleanisEmpty() { return map.isEmpty(); }
public SetkeySet() { return map.keySet(); }
public Object put(Object key, Object value) { return map.put(key,value); }
public void putAll(Map map) { map.putAll(map); }
public Object remove(Object key){ return map.remove(key); }
public intsize(){ return map.size(); }
public Collection values() { return map.values(); }
public String toString(){ return
StateContainer[map= + map.toString() + ]; }
}
Whatever values the page author wants to be dynamic can be assumed to
be in state. Then, the Action author can make sure that the values
are there.
There is, by the way, good reason to use the composite pattern here.
I have discussed that before so I won't repeat it.

I'm switching back to using Tiles instead of Sitemesh and I remember one
issue that I found annoying with Tiles and I'd be curious how you guys
handle it. Say I have a form that is going to be reused for both Edit
and Add. I want the title attribute to read something like Add
Employee or Edit Employee, depending on what I'm doing. It seems
silly to have to create multiple definitions in my tiles-definitions
that are essentially the same exact definition except that the title has
changed (potentially you might want a definition to be used for more
than just the two that I mentioned). This also requires that my struts
config has to be set up to forward to multiple tiles definitions when
its really the same page layout but with a different title and could
really just require one definition to use.
I've thought of different ways I might want to handle this (ie set a
title in request scope before leaving action and have the header.jsp
look for this, or maybe use a filter or over-ride RequestProcessor?) I'm
curious if others have run into this. Maybe the latest Struts/Tiles has
a solution that I have not looked into.
Thanks

Re: How to add your own validation + make use of existing validator
finally i could figure it out as ActionErrors errors = super.validate(...) ( i am new to java too) With this i could get the server side validation + my own validation. The same thing i want to do it for Javascript validation. I want to make use of JavaScript validation created by validator + i want to add my own javascript validation any idea ? regards Manisha Manisha Sathe [EMAIL PROTECTED] wrote: I am using validator framework.
