Can't make html:checkbox CHECKED by default

[otisg]

Hello,

I am using  Struts tag, but I am unable to set
it
to a CHECKED state by default (I read the docs).

This is what I am using now: 

 

Is 'value' not the attribute I should use for that?
Which attribute should I use then?

Any help would be appreciated.
Thanks,

Otis

Re: RE: Looking for junior Java/Struts developers

[otisg]

Hello,

Just noticed this thread.
If the original sender is still looking for a Java/Struts
developer, I know several good ones in Zagreb, Croatia.
The cost of living in Croatia is much lower than in the U.S. and
wester Europe, so they are much more affordable.

If you need more information, leads, etc., feel free to contact
me.

html:checkbox - default check state - how?

[otisg]

Hello,

I am using html:checkbox Struts tag, but I am unable to set it
to a CHECKED state by default.
I checked the docs for the Struts HTML taglib, but found nothing
that worked.

This is what I am using now (removed gt and lt to avoid HTML
rendition problems): 

 html:checkbox property="foo" value="true"

Any help would be appreciated.
Thanks,
Otis

Re: ActionMessage(s) + html:messages

[otisg]

Hello,

I still haven't resolved the problem described in the original
email, so here is some sample code that should illustrate the
problem with ActionMessage(s) and html:message tags futher.

The code that uses ActionError(s) works when used with
html:messages tag.
The code that uses ActionMessage(s) does _not_ work with
html:messages tag, even though it looks like it should be
equivalent to the lines that use ActionError(s).

  // ActionErrors errors = new ActionErrors();
  ActionMessages errors = new ActionMessages();
  // errors.add(ActionErrors.GLOBAL_ERROR,
 new ActionError("error.auth.failure"));
  errors.add(ActionMessages.GLOBAL_MESSAGE,
   new ActionMessage("error.auth.failure"));
  // saveErrors(request, errors);
  saveMessages(request, errors);
  return mapping.findForward("failure");


I am using html:messages like this:

  

  


The above JSP snippet works fine with ActionError(s) code above,
but _not_ with ActionMessage(s) code, which is also above.

Am I doing something wrong here?

Thanks,
Otis

ActionMessage(s) + html:messages

[otisg]

Hello,

I am trying to use ActioMessage(s) + html:messages to display
error and non-error messages in the UI.

However, my html:message tag is showing only messages set by the
validator, and not the messages that I am trying to set inside
an Action, like so:

  ActionMessages errors = new ActionMessages();
  errors.add(ActionMessages.GLOBAL_MESSAGE, new
ActionMessage("error.auth.failure"));
  saveMessages(request, errors);
  return mapping.findForward("failure");

In the JSP layer I use html:messages like this:

  

  

  

Am I using these two things incorrectly?

Any help will be appreciated.  I found example usage of
html:messages in a few Struts-related web pages, but none
described how it works when you set ActionMessage(s) in an
Action class.

Thank you,
Otis

validwhen released?

[otisg]

Hello,

I would like to use validwhen validation rule, but I am unsure
whether the recently released Struts 1.1 includes this.  I heard
that it does, but according to
http://jakarta.apache.org/struts/userGuide/dev_validator.html,
validwhen will be released in a release after the 1.1 release.

I was wondering if anyone can clear this up for me.
Also, if validwhen is not in 1.1, I would be curious to know
when a release with validwhen will be made.  We need this for a
web app that is supposed to go in production by the end of July
2003.

Thank you,
Otis

Re: FW: Running unit tests for Validator used with Struts

[otisg]

Hello Edgar,

I already am using StrutsTestCase to tests
Actions I write.  I see how that could be
used to test whether validation works, but
unless I'm missing something testing of
custom validators this way would really be
just a side-effect of testing Actions.

So imagine you have an Action A that uses
Validator V.  I write a STC-bases unit test
and run it.  It passes, no problems.  One
day somebody modifies A to stop using V and
modifies V and breaks it.

My STC-bases tests keep running and passing,
because A still works, but I will never find
out that V is broken, because V is never
really tested directly.

A new developer is hired and writes a new
Action, AA, and decides to use V.  V is
broken and his AA class is now broken
because V is kaput.

One could argue that AA should have its unit
tests, too, and that those should show me
that V is (has been) broken

So I will use STC for testing the Validator,
too, but I'm wondering if there is better,
more direct way of testing them?
I can test them directly when they are
Struts-independent, but when they depend on
Struts (e.g. by taking some Struts classes
as params), then I cannot.

Thanks,
Otis

Re: JUnit Error

[otisg]

I don't have a solution, but I saw this,
too, but only when running JUnit tests from
Eclipse.  When I run them from Ant I did not
see this problem.

Decoupling custom Validators from Struts

[otisg]

Hello,

All the Validator examples that I have seen
seem to be tightly couples with Struts.
For instance, most validateXXX(...) methods
takes the following types as parameters:
  Object
  ValidatorAction
  Field
  ActionErrors
  HttpServletRequest

Because of presence of ActionErrors, this is
tightly coupled to Struts.
What happens when one day we decide to
replace Struts with XYZ? We have to rewrite
a piece of this Validator.

Because of presence of HttpServletRequest,
thi is usable only in the Web App context.
What happens if we want to use this
Validator in a desktop application?

I am wondering how one would create a custom
Validator that did not have these 2
dependencies (or at least not the Struts
dependency).

If I write a custom Validator with a method
such as:
  validateXXX(Object, Field)

How do I use this method in a Struts
application without passing it instances
Struts-specific classes, such as
ActionErrors, and still somehow end up with
error messages suitable for showing to the
user, etc.?

I have seen code such as the following, but
this would require that a developers
manually inserts error messages into an
instance of ActionErrors, etc.  Is there no
better way?

ValidatorResources resources = new
ValidatorResources();

InputStream rules = 
ValidateExample.class.getResourceAsStream("validator-rules.xml");
ValidatorResourcesInitializer.initialize(resources,
in);

InputStream forms = 
  
ValidateExample.class.getResourceAsStream("validation.xml");
ValidatorResourcesInitializer.initialize(resources,
forms);


// Suppose we already had a CheckoutForm
object created and populated
CheckoutForm form = new CheckoutForm();

// Create a validator with the checkoutForm
Validator validator = new
Validator(resources, "checkoutForm");

// Tell the validator which bean to validate
against.  
validator.addResource(Validator.BEAN_KEY, form);

// Validate the checkoutForm object and
store the validation results
ValidatorResults results = validator.validate();


Thanks.
Otis

Alright, thank you!

One more thing, though.
So I have input="/myWebApp/SetUpCountryForm.do"

But this is a real URI.  Who will forward to
this URI?  Does Struts do that somehow
behind the scenes, or do I have to somehow
get the value of 'input' attribute, convert
that into ActionForward somehow, and return
an instance of that ActionForward from my
ProcessCountryForm's execute(...) method?
(e.g. return mapping.getInputForward(); )

Thanks,
Otis

RE: RE: handling form errors in Actions, returning to form, prepopulating them without re-POSTING

[otisg]

Aha!  Thank you for clarifying this.
So, in Struts config-speak, is this all that
is needed to do what you described:



  
  
  
  

  
  
  
  




In addition to this, the actual JSP has to
be non-static, that is, it is JSPs
responsibility to take any data it needs
from the HTTP Request and populate the HTML
form with it, is that correct? (i.e. this is
not done auto-magically by Struts - it is up
to the JSP developer to add code to do that
to the JSP)?

Thank you,
Otis

Re: RE: handling form errors in Actions, returning to form, prepopulating them without re-POSTING

[otisg]

Thanks.
However, that thread really says one thing -
put everything in session scope and don't
worry about it :)

But how does one do these things:

A. Get the user back the input form

-- Is it by just finding a 'failure' forward
that points to the original JSP with the form?

B. Display the error message

-- I guess the errors are saved either in
Session or Request, ok.

C. Make sure that all possible fields are
   pre-populated with data that the user
already entered

-- Is this up to the JSP develop to do,
perhaps with the help of
   some Struts JSP tags or does this happen
automagically?

D. The pull-down in the form has that same
   list of countries

-- Yes, a developer could just save this in
Session scope, but if that is not desired,
then how is this re-retrieved if the user it
forwarded to a JSP?  The user would need to
be re-sent to the original action that
retrieved the list, no?

E. The user is not prompted with 'Do you
   want to re-POST' dialog

-- Does this happen automagically?

Thanks,
Otis

handling form errors in Actions, returning to form, prepopulating them without re-POSTING

[otisg]

Hello,

We are starting to use Struts and are
wondering how Struts users handle scenarios
such as this one:

1. /ShowForm action gets called, mapped to
ShowFormAction.
   ShowFormAction pulls a list of countries
from the DB (for ex.),
   stick that list in the HTTP request, and
'forwards' to 'ok', 
   which is a JSP with a form that consists
of blank form fields
   and a pull-down with countries that it
gets from the HTTP req.

2. A user fills the form, but forgets a
required field before he
   submits the form by POSTing to
/SubmitForm action.

3. /SubmitForm is mapped to SubmitFormAction
which detects a
   missing required field.  Is puts error
messages in an instance 
   of ActionErrors.  It now needs to forward
to something other
   than 'ok'.

What we want to happen at this point is:

A. Get the user back the input form
B. Display the error message
C. Make sure that all possible fields are
pre-populated with
   data that the user already entered
D. The pull-down in the form has that same
list of countries
E. The user is not prompted with 'Do you
want to re-POST' dialog

How can this be done?

In our Struts config we have:














What is the best way to handle this and
achieve A, B, C, D, and E that I mentioned
above?

If SubmitFormAction encounters an error
(e.g. a missing required field), what should
it forward to?  The original JSP in 'input'
attribute?  The JSP mapped to 'failure' (the
same JSP with the original form)?
Should it forward/chain to another Action
that redirects back to the original form?
(but that would lose the form data + error
messages in the Request, wouldn't it?) 
Something else?
Does the JSP with the form need to contain
the logic for pulling errors + form data
from the request, if it exists?

This seems like a situation that would be
very common and I feel that Struts has some
elegant way for handling this.

Thank you,
Otis

Writing unit tests for custom Validators

[otisg]

Hello,

I am wondering how people write unit tests
for Validators for Struts.
Examples of Validators that I have seen all
take arguments such as:
org.apache.commons.validator.Field
org.apache.commons.validator.ValidatorAction

It seems that these 2 classes take
information from validator-rules.xml and
validation.xml files and I assume Struts
takes care of instantiating Field and
ValidatorAction properly based on these files.

But if I want to write a unit test, how do I
instantiate Field and ValidatorAction with
the information from those 2 Validator files?

Do people use
org.apache.struts.util.StrutsValidatorUtil
to get this information from Struts and then
use that to instantiate Field and
ValidatorAction properly?

Are there any examples of that anywhere, so
I can get the starting skeleton?

Thanks,
Otis

Yes, I have that, too:

RE: RE: Validator won't kick-in

Hello,

No, I don't have that.
I jut added it and tried it, but it didn't
change anything - Validator still didn't
kick in.
I have not seen this mentioned in any docs.

Any help would be appreciated.

Thank you,

Re: RE: Validator won't kick-in

[otisg]

Yes I did :)
My original email actually shows that my
'loginForm' is of type
org.apache.struts.validator.DynaValidatorForm

I am also using input="..." in the action
mapping.

Here is the action mapping in question:

Validator won't kick-in

[otisg]

Hello,

I am trying to use Commons Validator with
Struts, but I can't get it to 'kick in'.  I
am using the CVS HEAD version of Struts and
Taglibs, and Validator I just built from CVS
the other day.

My Struts config has a 'loginForm' defined as:







The 2 Validator's files are defined properly
in Struts config via .

IN Struts config I have /Login action tied
to the loginForm form.  I also have
validate="true" set in the action mapping
(is this needed?).


In my JSP that contains this loginForm I
have action=/Login in the HTML form.  Fields
are 'username' and 'password'.


My validation.xml contains:










My Action class does not contain any code
that calls form.validate(mapping, request).
 I don't think this is needed - I think
everything should work as defined
declaratively in these filesautomagically :)
...
...but it does not do that (for me) :(


I've read Chapter 11 of Cavaness' book a few
times and according to him what I described
above should suffice.

When I go to my login page with the login
form and leave the username completely blank
I expect to get an error...but I don't get it.

One more thing that may be worth mentioning,
my Action class has:

return mapping.findForward("success");

And the JSP defined for this "success" contains:



I expect this to show me Validator's errors.
I get no application errors, all looks good,
too good - I want to see that error about a
missing required username field :)

Thanks,
Otis

en_US prefix for resource key? Why?

[otisg]

Hello,

This must be a simple one to answer to
experienced Struts / JSP / taglib users.  I
am using the latest Struts (CVS HEAD) with
Taglibs.

I am trying to make use of ActionError(s)
and messages defined in resource files, but
instead of an appropriate error message I
get something like
"???en_US.amp.error.invalidLogin???"
I know why I get the resource key instead of
"", but I shouldn't be getting the resource
key - I want to get the resource value text.

My resources file is called
AMPResources.properties and is defined in
Struts config as:




My JSP file contains:




My Action class contains this:

ActionErrors errors = new ActionErrors();
errors.add("username", new
ActionError("amp.error.invalidLogin"));

if (!errors.isEmpty())
{
saveErrors(request, errors);
return mapping.getInputForward(); //
login.jsp
}


The AMPResources.properties file is in
/WEB-INF in the WAR.

Is the file named wrong?  Why the en_US prefix?

Thanks,
Otis
P.S.
My problem is similar to this one:

Re: Re: How to forward from a struts form to a login dialog ?

[otisg]

Oh, one more thing.
Note how in this servlet filter some
application-specific URIs are hard-coded. 
It would be more elegant, IMHO, to declare
those elsewhere.
Also, instead of sending a redirect to a
hard-coded URI, one could use sendError with
401 code (unauthorized) and then handle 401
declaratively in web.xml, like this for
instance:


401
/loginView.do


What do people think?  Is this better or not?

Otis

Re: Re: How to forward from a struts form to a login dialog ?

[otisg]

Hello,

Thanks for the classes, I am doing the same
thing.
Question:
- What's the advantage of using the entry in
web.xml (maybe you can also send web.xml?),
and doing the naming lookups, etc. versus
just storing an object in a HttpSession and
checking if it is null or not (as you are
doing as well).
What does the naming stuff give you?

Just curious...
Thanks,
Otis

Re: Re: DispatchAction and 'input' param in struts-config

[otisg]

If I understand you correctly, those 2 pages
would then be _nearly_ identical - the main
difference would be that one may have a form
with:



while the other one may have:




Is that what you are saying?

I think I was just forcing the use of
DispatchAction in my particular case.  Yes,
when 2 operations are _really_ similar, then
this will work, but when they are not very
similar, then one may be better of just
having 2 distinct Action classes.

Thanks,
Otis

Multiple but identical pages, is what you

If that is so, then I am doing something
wrong, and that is probably that I am
forcing the use of DispatchAction when I
should really be using 2 distinct Action
classes instead.

DispatchAction and 'input' param in struts-config

[otisg]

Hello,

When using DispatchAction to group multiple
activities in a single action class, how
does one deal with struts-config.xml?  I
didn't see this addressed in any Struts
articles nor in the Javadoc.

In particular, how does one use action's
"name", "input" and "validate" attributes of
the "action" element?

One can specify only 1 "name", and only 1
"input", but if one if grouping multiple
activities in a single action class, there
are usually multiple names (forms) and
inputs (pages with forms).

Example:
Consider AccountManager class (a subclass of
DispatchAction) with 2 methods: create and edit.
The 'Create Screen' might contain a form
with only 2 fields:
first name, and last name.
The 'Edit Screen' may contain a form with
more fields:
email, address, etc.

So how does one specify "name" and "input"
here, when there are really 2 different
names and inputs here?

Does one have to code the templates/pages
with the logic that renders the appropriate
form based on the activity (create or edit)?


Similarly, what happens with 'validate'
attribute of an action?
How does one determine which activity is
occurring when validate method is called, so
that the correct fields can be validated?
In the above example, how does one know
whether Create or Edit activity is happening?

Otis

DispatchAction - misleading Javadocs

[otisg]

Hello,

I would like to use DispatchAction, which
allows multiple 'execute'-like methods in a
single class.
One problem: DispatchAction's Javadocs do
not say how to configure struts-config.xml
to point to one's DispatchAction Action (the
Action that subclasses DispatchAction).

The Javadocs contain this example:




Oh, I see.  The problem in the above
example is the poor choice of 'type'
attribute's value.

The examples at
http://www.jguru.com/faq/view.jsp?EID=897290
are much better.
The example in the Javadoc is misleading.

It would be much better to use something like:
  type="com.example.actions.MyDispatchAction"

Hopefully Struts' developers are watching...

DynaValidatorForm vs. DynaValidatorActionForm ?

[otisg]

Hello,

I am looking at the Javadoc for
DynaValidatorForm and DynaValidatorActionForm:
http://jakarta.apache.org/struts/api/org/apache/struts/validator/DynaValidatorForm.html
http://jakarta.apache.org/struts/api/org/apache/struts/validator/DynaValidatorActionForm.html

I am wondering what exactly the difference
between them is.

Judging from the Javadoc it looks like
DynaValidatorActionForm overrides validate
method of DynaValidatorForm, but the Javadoc
does not indicate what is different in the
implementation of DynaValidatorActionForm's
validate implementation.

Does anyone know?

I looked at the source, and the method
implementations look identical.
Are there future plans that will make them
different?

I am just trying to decide which one to use.
 All Struts articles that mention these 2
classes are super vague about which one to
use.  They just say use one or the other. 
But when should I prefer to use one or the
other?

Thanks,
Otis

(solved) Re: Re: Can't map HTML form action to Struts action

[otisg]

For those who see this error in the future:

This turned out to be a problem with
slightly invalid XML in struts-config.xml,
not web.xml, as the error may lead you to
believe.
The tool that helped me figure this out was
James Holmes' Struts Console application. 
Nice work, thanks.

Re: Can't map HTML form action to Struts action

[otisg]

Hello,

I see.  I thought
org.apache.velocity.tools.view.servlet.VelocityViewServlet
replaces Struts' ActionServlet.  However, it
seems that it is not an alternative Action
Servlet for use with Velocity, as I thought,
but rather an additional servlet capable of
dealing with Velocity templates, and not
with action mappings and such.

I still have a slight problem:

[2002/12/24 09:26:18] init exception for
`action'
javax.servlet.UnavailableException: Parsing
error processing resource path
at
org.apache.struts.action.ActionServlet.initModuleConfig(ActionServlet.java:931)
at
org.apache.struts.action.ActionServlet.init(ActionServlet.java:454)

That 'action' must be referring to this part
from web.xml:


action
   
org.apache.struts.action.ActionServlet

config
   
/WEB-INF/struts-config.xml


debug
2


detail
2


validate
true

2



action
*.do



Am I doing something wrong?  This is a
copied from one of the Struts examples.
It looks fine to me...

Thanks,
Otis

Can't map HTML form action to Struts action

[otisg]

Hello,

I am having difficulties hooking up an HTML
form action to an action mapping defined in
struts-config.xml.  This is the Struts HEAD
from CVS.  I am using Struts with Velocity.
 I can get .vm templates to load, but can't
get things like HTML form submission action
to map to a Struts action.

My web.xml contains:


   
MyVelocityViewServlet
   
org.apache.velocity.tools.view.servlet.VelocityViewServlet
...



   
MyVelocityViewServlet
*.vm



My struts-config.xml contains:









My HTML form contains this:



When I submit this form I get a 404 from the
servlet container:

404 Not Found
/foo/login was not found on this server.

I've looked at several configuration
examples, and what I have looks fine, but
unfortunately it is not.  I am using this
with Resin 2.1.6.  One suspicious thing that
I notice in Resin's log after I submit the
HTML form is this:

[2002/12/24 00:05:24] file: init
[2002/12/24 00:05:24]
com.caucho.server.http.DirectoryServlet: init

This looks as if Resin is not mapping my
/foo/action to the action servlet defined in
my web app's web.xml...maybe, not sure.

I have tried mapping /foo/* to
MyVelocityViewServlet in web.xml, but that
resulted in .vm pages being rendered as
text/plain.  That may be fixed by
associating .vm extension with text/html,
but I'm not sure how to do this under Resin
yet.  But I think I have something else
wrong, anyway.

Thank you,
Otis

[otisg]

Thanks.  Of course, I was looking at the DTD
yesterday, but today I forgot about it :(

struts-config: action's "input" attribute purpose

[otisg]

Hello,

Warning: new Struts user.  Trying to use it
with Velocity, actually.

I'm writing struts-config.xml for my web app
and I'm wondering about 'input' attribute of
the 'action' element.
What is it for, and how is it used?
I am asking because I see mixed examples -
some using that attribute, some not.  And
that 'input' attribute is not listed at
http://jakarta.apache.org/struts/userGuide/building_controller.html

What happens if I use 'input', and what if I
do not?

Thanks,
Otis

StrutsValidator - error while compiling 1.1 beta 1

[otisg]

Hello,

I am trying to compile Struts 1.1 beta 1
from source using ant and I'm getting the
following error:

[javac]
/usr/local/src/java/jakarta-struts-1.1-b1-src/src/share/org/apache/struts/util/StrutsValidator.java:145:
exception
org.apache.regexp.RESyntaxException is never
thrown in body of corresponding try statement
[javac] } catch (RESyntaxException e) {


I found some old posts mentioning that this
is due to jakarta-regexp -> jakarta-oro
switch, so I made appropriate changes in
build.xml and build.properties, so now this
is what I have there:

# grep regexp build*
build.properties:regexp.jar=/usr/local/jakarta-oro/oro.jar
build.xml:  
build.xml:


This looks right to me, and it matches
changes that I got from CVS change log for
these files.

Yet, I get that error when compiling.
Do I need to make any other changes?
Jakarta-oro jar is before jakarta-regexp jar
in my CLASSPATH, too.

Thanks,
Otis
