Thanks Chris and Paul.

We tried it ourselves, and it turned out that it is working fine. I
guess the documentation (for both Struts 2 and WW) needs to be updated
to remove this section.

Tarek,

The Struts framework should be using the locale of the user. If you want

to grab a certain language, have you set the locale first?

 Hi,

 I read the following in the documentation

 Errors are reported using the default validation message, not the
 internationalized version that the server-side might be aware of.
This
 is a known issue. You may want to try the AJAX Client Side Validation
 for messages that are fully internationalized.

 Is this feature impossible to implement using the current framework?
I
 don't want to go to the server for simple client side validations and
 the internationalized messages are a must for me.

 I looked at the code and it seems that this expression is the one
that
 yields the message
 ${validator.getMessage(action)?js_string}

 I'm not into freemarker but it seems to be calling something on the
 validator object. Is there a way we can enhance the validation object
in
 some way so that it exposes the internationalized message or is this
 object not aware of the user's current locale at all? Could it be
 enhanced so that it is aware of it?

 Thanks,

RE: Parameters not being set on Action in Struts 2

2006-12-01 Thread Tarek Nabil
Thanks Ted.
 
This is getting interesting. I was really surprised that it worked for you, I 
couldn't even wait til the weekend is over. On my extremely slow laptop at 
home, I went and downloaded Tomcat 5.5.20 and Struts 2.0.1, and tried it. 
Surprisingly, it DOES work!
 
I've been trying this from the very first day inside JDeveloper. Just to 
eliminate the probability that it might be the embedded OC4J that has the 
problem, I installed the application on a standalone OC4J and I found that it 
exhibits the same behavior as the OC4J embedded inside JDeveloper. So, I guess 
that means one of two things:
1- This is a bug with OC4J (more likely)
2- The code uses some non-standard feature that is not supported by OC4J (very 
unlikely)
 
Since Oracle AS 10g is our target platform, this could be a show stopper for 
us. It would simply mean that if this issue can not be resolved then we can not 
move to WW/Struts 2.
 
I'm open to any suggestions on how to get to the bottom of this issue.

RE: Does Struts 2 solve the action chaining problem?

2006-11-30 Thread Tarek Nabil
Craig and Mark,

Thanks a lot for pointing out the Preparable interface. I think that
solves a major problem with Struts 1. I'm yet to experiment heavily with
WW/Struts 2, but I feel like the Interceptor concept is a very
powerful approach, though a bit dangerous if not well controlled.

Craig,

We, actually, decided that we don't want to get into JSF yet. But if
this prerender method is equivalent to the onPageLoad() method in
ASP .NET, then it's a very important piece that is really missing from
the JSF spec.

Yujun,

Your idea is brilliant and it never crossed my mind. If we stick with
Struts 1, I think I will try that.

Christopher,

I really wonder if the Struts you're talking about is the one I've using
for years now!! The Struts I know sucks big time when it comes to action
chaining. I'm afraid I don't understand how defining two mappings, one
with validation turned on and the other turned off, solves the first
problem! As for the second problem, your solution still involves action
chaining which should be avoided unless you've done something equivalent
to what Yujun did.

Thanks everyone for your help.

 A solution to that would be to specify the input of the action as the

not

 The solution of choice for us so far was to call validate() ourselves
in
 the action and if a validation problem occurs then we call the setup
 method (eventually you start using your action methods as an API which
 still was not good).

I totally disagree. If you have an action that you want to use like
this, you can always set up two different mappings -- one that /does/
validate and another that does /not/ validate.

My experience has been that Struts is very good at action chaining...
in fact, that's the major advantage of Struts in the first place: the
ability to map URIs to actions and specify their relationships through
forward mappings.

 Another problematic scenario is the case when you're editing some
 database record for example. When you go to your setup action for the
 first time, you will populate drop down lists for example, and then
load
 the existing values from the database to your JSP fields. If the user
 attempts to save and some problem occurs then in the setup action, you
 will need to again populate the drop down lists, but you will NOT want
 to overwrite the user's inputs with the existing data. This is very
 similar to the first problem, but you would also need to pass some
flag
 to the setup method to tell it whether to copy the data from the
 database to your ActionForm.

In this case, what you want is something like:

LoadAction - EditAction - Display form

Form submits to SaveAction, which has EditAction as input (not
LoadAction).

This is pretty standard stuff, and works beautifully.

 Does Struts 2 or even WW 2.2.4 solve that problem in an elegant way?

I really hope so, since Struts 1.x also does.

   logger.debug(ActionContext.getContext().getParameters());

I added tried calling ActionContext.getContext in one of my own
Actions and set a breakpoint in IDEA, to be sure it works correctly.

One thing to not about type property is that it is an integer, so be
sure your test is passing an integer as a parameter. That should
affect the map, but it would affect what's set to the property.

If time is going to be an issue, I'd strongly recommend trying an IDE
with integrating debugging, since a quick step through can save a lot
of temporary logging statements. The W2/S2 framework is also very
testable, and nothing saves more development time than a solid set of
unit tests from the get-go.

If your application does need to do alot of logging, a very good place
to do that is from an Intercetpor, so that the logging can be applied
uniformly.

2- If a property on the action has the same name as one of those
parameters then the framework will attempt to set the property with the
parameter's name.

This is not what is currently happening. Since WW 2.2.4 is supposed to
be production quality then I'm guessing that there must be something
wrong with the configuration. It can not be that some configuration I've
provided is wrong, simply because I have not provided any. It could be,
though, that some configuration is missing.

Thanks Peter and Ted.

I'm afraid I didn't understand your advice regarding the IDE with
integrated debugging. Would that require me to use the source of Struts
2 rather than the JAR files as part of my application?

To keep things simple, I started an application from scratch. Kept
things to the bare minimum and I can still confirm that the problem

RE: Parameters not being set on Action in Struts 2

2006-11-25 Thread Tarek Nabil
Thanks Ted.

I renamed my method to execute and changed the URL to remove the
!setup part.

I also changed the struts.xml file accordingly, so now it's like that
(note that I removed the input result, just in case it's causing any
problems).


action
name=dod1
class=packagename.ActionClassName
result name=page/jsp/billCreation/PageName.jsp/result
/action

I was pretty sure that the correct method was being executed, because I
had some logging statements inside. One of those statements is the one
that attempts to log the parameter Map and it's still giving the same
result; an empty Map.

I know you guys are doing a great effort trying to get this framework
out, but if I have a project starting in one month and delivering four
months later, would you recommend Struts 2 for that?

Please note that means that most development will be done using a
pre-release version, so do you think this version is stable enough to be
used by a team of 30 to 40 people where delays could cause a great
damage?

And, although I know this question is very difficult to answer for OS
projects, do you think this framework will be ready for prime time in 5
months? The application is a heavy transactional one and is required to
scale for thousands of transactions per day.

Your advice is greatly appreciated.

First, simplify the problem. Right now, the code seems to be calling
an alternative method, setup. What happens if you try the same thing
with the default execute method?

If your application is based on the blank application, it may turned
the ! syntax off, since it can conflict with using wildcards. To use
the Check the struts.properties file for the line
struts.enable.DynamicMethodInvocation, and set it to true.

We're working on some new code for Struts 2 that will extend the !
syntax so that it can happily coexist with wildcards.

I started looking into the Extending Themes topic, but it seems that
there's no clear reference on how to do that. Following the examples
does not seem to be very easy as I have not found any reference to

explains all the attributes exposed by parameters.

Could some one please point me to such a reference if one exists?

RE: Is Action Chaining Strongly Discouraged?

2006-05-06 Thread Tarek Nabil
 
Dave,

I'm not sure if you really read my message thoroughly. When I meant
population, I meant for things like drop down lists, not for edit pages
that come pre-populated with existing data to edit. If you always go
back to the same page, then populating the drop down list has to be done
whether you're going to the page directly or after an add/update, so
that's why I was asking about redirecting, I thought you were doing the
update then redirecting to the action that does the setup.

As for the two approaches I've been asking for comments on...they're not
the one below, bu the ones at the end of my email:

1- Put the setup information in the ActionForm class itself (not very
inclined to go for that one).
2- Using a MappingDispatchAction without action chaining. Put the setup
code in common methods in the action class. Configure two mappings for
the same action class that will call two different methods, e.g. prepare
and add. In both methods, I would call the common setup method before
going back to the page, so it's minimal duplicated code (although
duplication is not completely eliminated), but at least it's less
awkward than retieving the form from the request scope by hand.

Of course in number 2 above, I don't mean that the actual database call
is in the action, but the call to the service method.

Thanks

Who, me? If no, ignore the following.

I'm not sure I understand the question. In a nutshell: for a GET I do
whatever population/misc. stuff I need to do then return the input
forward. For a POST I validate and return the input forward if there are
errors, otherwise I return whatever forward is warranted.

In practice by classes have become more cumbersome than that with
methods designed to be overridden that do pre- and post-processing etc.

 I've been thinking about this action chaining issue for some time 
 since I used it in my last project and it resulted in some code
duplication.
   

Isn't that bass-ackwards? Even though I really dislike chaining
shouldn't it have less code?

 1- A prepare action when the page is called directly (a form bean is 
 configured for that one).
 2- A page action when it's called from another action (no form bean is

 configured to prevent resetting).
   

*shudder*

If no other reason here's a strong reason to move that logic out of the
actions and into service objects; at least then you're just making calls
rather than duplicating the code. Unless I completely misunderstood you.

 Would anyone care to comment on those two approaches? Does anyone have

 a different approach that I can consider?
   

At first glance with no clue what you're trying to accomplish it sounds
overly complicated.

RE: Is Action Chaining Strongly Discouraged?

2006-05-02 Thread Tarek Nabil
Dave,

Do you mean that you're doing a redirect after processing the post?

I've been thinking about this action chaining issue for some time since
I used it in my last project and it resulted in some code duplication.
The reason is, I was storing the setup data in my form (which I still
think is better than using multiple objects stored in request scope
under multiple keys). When doing the chaining, I didn't want my form to
get reset and lose all the request data when going to the second action,
so I had to configure two action mappings for the same action:
1- A prepare action when the page is called directly (a form bean is
configured for that one).
2- A page action when it's called from another action (no form bean is
configured to prevent resetting).

In the execute method, I was checking whether the form is null, and if
it is, I would retrieve it from the request scope. I felt later that
this was an awkward approach.

Now, I have two more solutions that I'm considering.
1- Put the setup information in the ActionForm class itself (not very
inclined to go for that one).
2- Using a MappingDispatchAction without action chaining. Put the setup
code in common methods in the action class. Configure two mappings for
the same action class that will call two different methods, e.g. prepare
and add. In both methods, I would call the common setup method before
going back to the page, so it's minimal duplicated code (although
duplication is not completely eliminated), but at least it's less
awkward than retieving the form from the request scope by hand.

Would anyone care to comment on those two approaches? Does anyone have a
different approach that I can consider?

Re: Validation Configuration for Multiple Modules

Thanks Adam.

I'm sure no one will be able to verify whether this was a bug in 1.1b2 
(why I'm using b2 is a looong story, but I'm stuck with it).

Is there a way I can find out from Bugzilla whether this was a bug that 
was fixed in later versions?

Presumably in each module's struts-config, your validator plugin node 
refers to the correct validation.xml?

I doubt it's a bug since I successfully set up modularised struts with 
seperate validation.xml for each.

Validation Configuration for Multiple Modules

2005-10-11 Thread tarek . nabil
Hi everyone,

I'm using *Struts 1.1* to build an application with multiple Struts 
modules.

I put my validations for each module in a seperate validations.xml 
file. For example, I have validations-a.xml for module a and 
validations-b.xml for module b. I then found out that although the 
validations are working perfectly for module a, they're not working at 
all for module b.

I kept tracing the problem even in the Struts source code, and reached 
the conclusion that the validations for one module overwrite the other. 
It seems that the FormSet objects are stored in a HashMap with the 
locale as the key, and since both formsets have the same locale, one of 
them overwrites the other. Are my conclusions correct or am I doing 
something wrong? Does that mean I have to put all my validations for 
the whole application in one file?

Please advise.

Thanks.
