Validator and DispatchAction

[Renato Romano]

I'm quite new to the validator framework, and was trying to figure out
how to use it. My situation is:
1) I want to perform server side validation, and so I made my form
extend ValidatorForm;
2) the action that processes my form is a DispatchAction, so I have
methods like edit, save list, all associated with the same form;
3) I call http://blabla/myapp/myAction.do?methodName=edit to have the
app present me with an empty form;
4) When processing this action, struts allocates the form and calls the
validate method, which of course causes validation errors to be
produced, and the request to be forwarded to the input element of my
action, which, as usual, is the same jsp which contains the form;
5) since the page finds some errors (the form is empty!!) they are shown
by the html:errors/ tag.

The only think I can imagine is to have a separate action in
struts-config, which takes no form and simply redirects control to the
jsp page which shows the (html) form. This should avoid Struts from
calling the validate method, and hence html:errors/ should show
nothing.

Of course this would change a bit the logic we already placed in the
application actions: for example action.do?methodName=edit in our
architecture should present an empty form, while action.do?m=editid=88
should fill the form with the properties of the object with id 88, and
then forward to the same jsp page, which then shows that object ready to
be modified. If my above consideration is correct I should define two
separate actions in struts-config, and let the links be something like
newObject.do (for the presentation of an empty form) and unchanged for
the loading of an object.

Is all this correct ?Are there alternative approaches? Should I quit
server side validation and only use client-side (which does not suffer
from this problem)?
Any help is very appreciated.

Re: Validator and DispatchAction

I ran into the same problem and converted all my DispatchActions to
Actions.  The downside is that there are more class files, but the mappings
seem cleaner, especially in handling the 'input' attribute for html:errors
/.

Also, using Actions lets me specify different values for the 'validate'
attribute.  For example, I use the same form to lookup a records as I do to
update it.  In the case of the lookup, the Action pulls an identifier from
the DynaActionForm that doesn't need to be validated (validate=false for
this mapping).  In the case of the update, full validation of all fields is
required, so validate=true for this one.

That's just what I supposed. DispatchAction are fine, but when you need
finer control Action fits best!! Maybe next time ;-))
Thanks anyway

RE: Validator and DispatchAction

[Barnett, Brian W.]

Set validate=false in your action mapping in struts-config. This tells the
struts framework not to call validate. Then in your action class you can
call validate where appropriate, i.e., the *save* method.

RE: Validator and DispatchAction

[Nicholas L Mohler]

Renato,

There is another solution that is clean.

We use one action class with multiple (3) mappings to support our
validation needs.  With our editor scheme, the user proceeds to a Top
page where they decide to Edit an existing or Add a new item.  They then
proceed to a Detail page where they build the item.  The validations for
the Top and Detail pages are different, and we use the same form for both.
We want our server side validation failures to return to the page that
caused the failure.  For the Top page, that is not an issue, since there is
only one possible page that could have caused the validation issue.  We had
to address the Edit and Add pages.

For this, we have three mappings:
Top - Handles initial requests for the Top page and actions from the Top
page.  In this case, the input attribute always returns to the same page.
This mapping uses Top validations.
Detail - Handles requests that originate from a detail page.  This mapping
uses Detail validations.  In this case, the input attribute always
points to the third mapping: ValidationFailure.  We additionally add a new
attribute that points to a specialized method in the action class.
ValidationFailure - Handles requests where the detail validation failed.
Uses a different parameter for the DispatchAction than the other two
methods.  Validation is set to false.  The available forwards are the same
as the Edit and Add forwards that are found in the Top mapping.

When the failure method is used, it takes care of any prep work that is
needed to return to the detail page.  For example, there are some DB values
that we put into the request (they should be in the session, but that's
another story) when we go to the page.  The failure method handles any of
the necessary prep work.  The last task is that we retrieve the parameter
that was used for the original DispatchAction and return the mapping that
will take us back to the page that caused the error.

In our case, we use LookupDispatchAction classes, and this works well and
is pretty neat.  Additionally, all of our action classes extend a custom
LookupDispatchAction class that implements the failure method as well as
a few other things that are generic for all of action classes.

Let me know if this helps.
Nick

Ok, I see one potential problem. Your methods are declared as throwing
ServletException and IOException, but for Struts 1.1 they should be declared
as throwing Exception.

 public ActionForward create(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
  ...

should be
throws Exception {


Try changing that and see how you get on.

Does your DispatchAction class, com.ewd.biztax.actions.Tr518page1Action,
contain a method named error?

Re: Validator and DispatchAction

[Venkat Jambulingam]

oops.. I did not understand your question about defining parameter for
the action mapping.

In my struts-config.xml, I have defined the parameters for the actions
as given below:

action-mappings

action name=tr518Form input=tr518page1.jsp path=/tr518page1
scope=request parameter=dispatch1
type=com.ewd.biztax.actions.Tr518page1Action
forward name=next path=/tr518page2.jsp /
forward name=exit path=index.jsp /
/action

action name=tr518Form input=tr518page2.jsp path=/tr518page2
scope=request parameter=dispatch2
type=com.ewd.biztax.actions.Tr518page2Action
forward name=next path=/tr518page3.jsp /
forward name=exit path=index.jsp /
forward name=previous path=/tr518page1.jsp /
/action

action name=tr518Form input=tr518page3.jsp path=/tr518page3
scope=request parameter=dispatch3
type=com.ewd.biztax.actions.Tr518page3Action
forward name=next path=/tr518page4.jsp /
forward name=exit path=index.jsp /
forward name=previous path=/tr518page2.jsp /
/action

action name=tr518Form input=tr518page4.jsp path=/tr518page4
scope=request parameter=dispatch4
type=com.ewd.biztax.actions.Tr518page4Action
forward name=next path=schApage1.jsp /
forward name=exit path=index.jsp /
forward name=previous path=/tr518page3.jsp /
/action

/action-mappings

Please let me know if this is the parameter you are talking about.

Thanks in Advance,
Venkat

RE: Validator and DispatchAction

[Steve Raeburn]

The error message you are receiving indicates that DispatchAction is trying
to find a method named 'error' in your class and it can't find one.

There's really only two reasons that could be:
  1. There should be a method named 'error' and there isn't one.
  2. There isn't supposed to be one but somehow you are attempting
 to call it with a URL like this:
   http://localhost:8080/myapp/tr518page1.do?dispatch1=error

Are you dynamically generating the URL? If so, that might be the problem if
it is generating an error returning a string like error=.

For what it's worth, I copied your code and it dispatches perfectly well
here. (BTW my previous message about Exceptions was a red herring. Although
you should be throwing Exception, I tried it as you had written and it
works.)

contain a method named error?

RE: Validator and DispatchAction

[Venkat Jambulingam]

Hi Steve,

I just saw your message now. You are correct. I disabled javascript
which is used to set the value of dispatch1 to something other than the
default value (errror). Your insight really helped me pinpoint the bug.
Thank you so much. I was about to drop the idea of using validators...
Thank you for all your time and effort.

Venkat

 [EMAIL PROTECTED] 08/27/03 01:42PM 
The error message you are receiving indicates that DispatchAction is
trying
to find a method named 'error' in your class and it can't find one.

There's really only two reasons that could be:
  1. There should be a method named 'error' and there isn't one.
  2. There isn't supposed to be one but somehow you are attempting
 to call it with a URL like this:
   http://localhost:8080/myapp/tr518page1.do?dispatch1=error 

Are you dynamically generating the URL? If so, that might be the
problem if
it is generating an error returning a string like error=.

For what it's worth, I copied your code and it dispatches perfectly
well
here. (BTW my previous message about Exceptions was a red herring.
Although
you should be throwing Exception, I tried it as you had written and it
works.)

RE: Validator and DispatchAction

[Venkat Jambulingam]

The solution is to use LookupDispatchAction instead of DispatchAction as
the former does not depend on javascript.

The problem:
I had three buttons on my page — save, next and previous. 

When a user clicks a button, I set a variable called dispatch to
corresponsing value using javascript. For save button, dispatch will be
set to save and so on. I use javascript to do this.

The DispatchAction would call the corresponding method based on the
value of dispatch variable. 

The problem started when I disabled javascript. By default the dipatch
was set to error value. Since I did not have a method named error in
my DispatchAction, I was getting methodnotfoundexception.

HTH,
Venkat

 Error]-[action

using validator with DispatchAction

[Martina Weise]

Hi, 

i dont know how to use the Struts validator together with DispatchAction (Struts 
1.1b1): 

in the validator.xml there had to be the 
- name of the form of struts-config (f. e. TestForm) 
- or the name of the path from struts-config (f.e. /test ) 

as soon as one of this appears, the validation gets started. 

If i only want to start validation with (/test?method=specialThing), i couldnt define 
it anywhere, as far as i see. 

So, the validation is started for e. g.: 
- /test?method=showLeftFrame 
- /test?method=showMainFrame 
- /test?method=specialThing 

therefore always the jsp, which is defined as input in struts-config is shown. 

Suppose i have a Frameset with two frames, in both frames are shown the same jsp now. 

Who knows a solution? Or do i have to extend Struts myself?

Best Regards, 
M. Weise 

Re: Validator and DispatchAction

[William W]

My solution :

I did a class MyValidator with two methods (verifyMethod and 
validateRequired)

---
private static boolean verifyMethod(
Object bean,
ValidatorAction va,
Field field,
ActionErrors errors,
HttpServletRequest request) {

String methodRequest = request.getParameter(method);
String methodsToValidate = field.getVarValue(method);

boolean validate = false;

if ((methodsToValidate != null)  (methodsToValidate.length()  0)) {
if (methodRequest != null) {
if (methodsToValidate != null) {
StringTokenizer st = new StringTokenizer(methodsToValidate, 
,);
String method =  ;
while (st.hasMoreElements()) {
method = (String) st.nextToken();
if (method.equals(methodRequest)) {
validate = true;
break;
}
}
}

}
}

return validate;
}

public static boolean validateRequired(
Object bean,
ValidatorAction va,
Field field,
ActionErrors errors,
HttpServletRequest request) {

  if (verifyMethod(bean,va,field,errors,request))
  return StrutsValidator.validateRequired(bean,va,field,errors,request);
  else
   return false;
}
--
In the file validaion-rules.xml I changed the validator required like this:
validator name=required
 classname=MyValidator
 method=validateRequired
 ...
/validator

Now , I can configure in the validator.xml the methods that I want to 
validate. For example :

 form name=logonForm
 fieldproperty=userId
   depends=required
 arg0 key=logonForm.email.displayname/
   var
  var-namemethod/var-name
  var-valueupdate,delete/var-value
/var
 /field
  /form
David, What do you think about this solution ?

Thanks,
William.

Re: Validator and DispatchAction

[William W]

I think that if I use DispatchAction with ValidatorActionForm I will have 
the same problem. How can I validate the form for diferents methods in the 
same Action ? Am I wrong ?
Thanks,
William.

You would currently have to write your own required
validation method and have it check a variable defined
by a field to see if it should perform the validation
or not.  Or define a separate set of validation rules
for each action and use ValidatorActionForm (which
uses the action path to retrieve the validation
rules).

Re: Validator and DispatchAction

[Raffy_Lata]

DispatchAction has a lot of things to improve on...use of declarative
exceptions is one...then there's this issue you brought up about the
validator...you may have to do programmatic validation to provide different
validation rules for each method in the DispatchAction for now..

Re: Validator and DispatchAction

[David Winterfeldt]

You can't use booleans in the depends, but there can
be dependencies setup between validation routines. 
You can make a method check pluggable validator and
have required and other validator depend on it. 
Although the default configuration has everything
depend on required so if required depends on something
else, everything should work fine.  Method would be
checked first and then if it passes required would be
next.

validator name=method
   classname=MyDispatchMethodChecker
   method=validateDispatchMethod
methodParams=java.lang.Object,org.apache.commons.validator.ValidatorAction,org.apache.commons.validator.Field,org.apache.struts.action.ActionErrors,javax.servlet.http.HttpServletRequest
   msg=errors.method/

validator name=required
   classname=org.apache.struts.util.StrutsValidator
   method=validateRequired
methodParams=java.lang.Object,org.apache.commons.validator.ValidatorAction,org.apache.commons.validator.Field,org.apache.struts.action.ActionErrors,javax.servlet.http.HttpServletRequest

Re: Validator and DispatchAction

[David Winterfeldt]

Actually, I think I take that back.  You want to
actually skip certain fields if it is an insert or a
delete.  Making a method validation that returns false
(fails) will stop all validation.  You really probably
want a dispatchMethodRequired validator and any other
ones so they skip that validation if it shouldn't be
checked.  The other Validator methods kind of work
like this with required.  Everything else depends on
required, but if you remove the dependecies all those
methods, like mask, check if the field isn't blank
before they perform the validation.  If it is blank,
mask returns true and doesn't really do anything.

 You can't use booleans in the depends, but there
 can
 be dependencies setup between validation routines.
 You can make a method check pluggable validator and
 have required and other validator depend on it.
 Although the default configuration has everything
 depend on required so if required depends on
 something
 else, everything should work fine.  Method would be
 checked first and then if it passes required would
 be
 next.
 
 validator name=method
 classname=MyDispatchMethodChecker
 method=validateDispatchMethod

methodParams=java.lang.Object,org.apache.commons.validator.ValidatorAction,org.apache.commons.validator.Field,org.apache.struts.action.ActionErrors,javax.servlet.http.HttpServletRequest
 msg=errors.method/
 
 validator name=required

 classname=org.apache.struts.util.StrutsValidator
 method=validateRequired

methodParams=java.lang.Object,org.apache.commons.validator.ValidatorAction,org.apache.commons.validator.Field,org.apache.struts.action.ActionErrors,javax.servlet.http.HttpServletRequest
 depends=method
 msg=errors.required/

   I think that if I use DispatchAction with
   ValidatorActionForm I will have
   the same problem. How can I validate the form
 for
   diferents methods in the
   same Action ? Am I wrong ?
   Thanks,
   William.

   You would currently have to write your own
   required
   validation method and have it check a variable
   defined
   by a field to see if it should perform the
   validation
   or not.  Or define a separate set of
 validation
   rules
   for each action and use ValidatorActionForm
 (which
   uses the action path to retrieve the
 validation
   rules).

Validator and DispatchAction

[William W]

Hi !

I have a UserForm, the fields are : userId and userName.
I have a UserAction that extends DispatchAction. The UserAction have  two 
methods (insert and update). For the insert method only the userName is 
required, and for update method the userId and the userName are required.
How can I can do a dependency validation with the validator.xml ?
Thanks,
William.
