Hi Arun-

following up on Antonio's suggestion-
did you look at setting the AD properties ?
http://jcifs.samba.org/src/docs/ntlmhttpauth.html#props
(and then restart the container)

?

I can only dupe this if I leave out the leading "/" (slash) in my namespace
attribute of my package.

Off the top of my head I'd say that the dispatcher is looking in a "/"
namespace (as opposed to the "" (empty string) namespace) and can't find the
action there (or is looking in "" instead of "/", maybe).

If you use the leading "/" in your namespace attribute (both in your S2
config file and in the tags) it should work. (Although I just tried it only
in config and not in the tag and that worked too, but I wouldn't recommend
it.)

Dave,
Thanks for the help here. I see the same thing happening now.

If I have a leading slash in my config file I can create a link with both
and action and a url but the action tag then only works if I have a leading
slash. If I dont then I get the 'cannot find action' error.

I can create a url tag with or without a leading slash.

If I dont have a leading slash in the namespace attribute in the config file
I cannot create a url at all.

It may be inconsistent. It maybe documented that way. It may be the case
that this demonstrates the correct semantics for both the url and action
tags, I don't know. I do know that I can make progress now and that makes me
happy.

I do wonder if this is correct. I am gonna have a good long look at docs
again and see.

Thanks all for the feedback. Especially Dave N.

Hi,
I am trying to reset a validator form after the form is submitted and a few
of the validations have failed.
Reset button used in the form clears out fields changed only since the time
the form is loaded. That is it does just the client side reset. One way that
i figured out was to submit the form back to the jsp so that the jsp reloads
with all the form field reinitialized.
Is there some other method of clearing out the form fields after it has
failed the validations defined in validation.xml?
Thanks in advance for all the valuable suggestions!

Do you want to clear out the form fields before redisplaying the form
after a validation error, or just allow the user to request a reset
after the form is redisplayed?

Usually you would want to retain the data the user input after a
validation failure, so they can correct mistakes without having to fill
the entire form in again. If you really want to reset the form to its
starting state before redisplaying, discarding the user's input, then
you would need to do that in your validate() method (remember, if you
don't already have a validate() method, that when you add one it needs
to call super.validate() to trigger the XML-based validation).

If you just want to provide a button the user can click to reset the
form, a 'submit' button and round trip through your action is the
correct way to do so. As you've realized, a 'reset' button just tells
the browser to restore the input values it received the last time the
form was loaded.

Hi Laurie,
Thanks for the quick reply.
I want to reset the form fields after hitting a reset button.
When I thought of going about it through the Action class way and tried to
clear out my form fields , strangely i noticed that the Action class's
execute method is never called if there are still certain validations
failing.
I read in struts flow explanation that Action class is only called if the
validations are passed through.
I dont know what other way to adopt.
Any suggestions?
Thanks

What Laurie is saying is that you can implement a validate() method and call
super.validate() before you do your custom processing (which seems to
include clearing out all form values?)

You can check to see if there were validation errors the same way the
workflow interceptor does; by checking for the presence of error messages.

Dave

On a normal form submit to an action with validation, if validation
fails, the request is forwarded to the input result and execute() is
bypassed, yes. So, you have two options:

1) as Dave reiterated, you can put your form reset logic in validate();
have your validate method detect the when the reset submit button was
pressed and, if so, clear the form.

2) use a 'cancel' button as the reset submit. A cancel button will (if
you configure the action appropriately) bypass validation and call
directly into your execute() method.

For my money, option 2 is the better approach, since cluttering
validate() with non-validation concerns smells a bit... :p)

It works fine for me too. Maybe it's a problem with the version of Maven

It's not obvious from the documentation, but the message come from the
'global message resources', which you configure via the
struts.custom.i18n.resources property in struts.properties. The
struts=messages.properties file mentioned is where the standard defaults
are stored.

So, create a resource bundle containing your customized error messages,
say my-struts-messages.properties, and place it in the classpath, then
add a struts.custom.i18n.resources=package.name.my-struts-messaes
property to your struts.properties configuration.

I'm not sure about this part. I would expect, assuming you implement
ValidationAware (e.g. by extending from ActionSupport), that you would
get a validation failure rather than a status 500 response. If you're
still experiencing that, post the corresponding error logs and stack trace.

Jeromy,

Thanks for the comprehensive reply. Looking at the documentation and the
example app, I am still not sure how to configure my action/response. I
am using tiles 2.

If I configure the autocompleter as such:

<s:label name="text" value="Search for Question Text:" />

<s:url id="search" namespace="/question"
value="/question/searchByText.action" />

<s:autocompleter theme="ajax" href="%{search}" name="text"
loadOnTextChange="true" loadMinimumCount="3"/>

It seems I need to return my result in JSON format correct? By returning
a JSON String from the action, how to I configure my response?

<action name="searchByText" method="searchByText"
class="gov.hhs.fda.datacall.web.struts.action.QuestionAction">
 <result name="success" type="tiles">question.panel</result>
</action>

If I use the tiles response type, I get a dojo parsing error because the
whole page is returned from the reply.

The example in the example app isn't very clear to me, as the action
returns a .JS file with the result hard coded, and not using any
template like tiles I might add.

Also, I think I found a bug? -- the namespace attribute seems to be
ignored when I pass href=%{search} to the autocompleter. I had to put
qualify the namespace in the value to get the correct action to be
invoked.

Any further assistance you might provide would be much appreciated...
MG

My 2c:
I think this is a bad solution and shouldn't be encouraged. It's
marginally better than writing a custom servlet.

Struts2 ResultTypes [1] are designed specifically for controlling the
type and content of results from actions to separate the view from the
model, even if the "view" is XML data. Accessing the response and
writing to it directly isn't necessary except in the rarest of cases.

For Ajax/JS libraries that use JSON, the JSON Plugin (JSON ResultType)
[2] will serialize your action into JSON automatically
The XSL ResultType will serialize your action into XML if you provide a
stylesheet [3]
The REST plugin includes code to serialize your action into XML using
Xstream. [4]

My point is, your action can setup a model (eg. a javabean matching the
model expected by AjaxTag), and the ResultType can serialize it to the
output stream. In this case I'd create a custom result type using
XStream, but you could also use a XML template in a Tile, or have a
ResultType that accesses the instance created by AjaxXMLBuilder.

As previously stated if you are writing directly to the response you need to
return null from the action. I am still not sure why you're using a tile
definition here.

As Jeremy said this is, however, probably a bad idea, considering that the
same outcome can be achieved in several different ways.

Using a JSON result will serialize your action to JSON automagically. You'd
use a "json" result (via the JSON plugin), not a tile. Or you could build the
JSON manually and configure a FreeMarker result.

Sure.

What example are you referring to?

http://struts.apache.org/2.0.11/docs/ajax-tags.html#AjaxTags-autocompleterTag?

When making an Ajax request for a component like <s:autocompleter.../> it's
unlikely you'd want to return anything other than JSON. (Other components or
component libraries may want other formats like XML or whatever.) Unless your
tile definition is creating JSON it's not going to work, and it's unlikely
that would be the best way to generate the JSON anyway.

When you configure the package does your namespace have a leading "/" (slash)
character? If it doesn't this can lead to dispatching issues.

Dave

I completely agree with Dave so I'll take a different tact.

Based on this example:
http://struts.apache.org/2.0.11/docs/ajax-tags.html#AjaxTags-autocompleterTag,
I would also take the approach of returning a JSON Result via the JSON
Plugin. Only the configuration changes for an XML result.

So, my form looks like this:

<s:url id="json" value="/JSONList.action" />
<s:autocompleter theme="ajax" href="%{json}" dropdownHeight="180"/>

So, my struts.xml contains the corresponding action definition with a
JSON result:

  <package name="example" extends="json-default">
    <action name="JSONList" class="package.ListAction">
      <result name="success" type="json">
        <param name="root">list</param>
      </result>
    </action>
  </package>

And my action method looks like this:

private ACEntry[] list;

public String execute() {
  list = populateList()
  return "success";
}

public ACEntry[] getList() {
 return list;
}

---
In summary, the autocompleter does a get to /JSONList.action
Struts2 executes the execute method of ListAction
The execute method creates a structure that will populate the autocompleter
The action returns a JSON result type
The JSON plugin converts the root object (the list property only rather
than the whole action) to a JSON structure
The JSON plugin returns the application/json content to the autocompleter

I'll leave it to you to determine what the list structure should like
like. As it'll probably be re-use I'd create a bean for the purpose.
Use the FireBug plugin for firefox to inspect the format of the JSON
result to ensure it matches the format required by the javascript
library (or even better, write a unit test).
This will work with any javascript library that accepts JSON - you just
have to provide an appropriate structure. It will also work with any
library that requires an XML response, except you'd use an XML result
type like I previously described in this thread.

I hope that helps. Struts2 is really well suited at providing non-html
responses if you take the time to understand the ResultType architecture.

cheers,
Jeromy Evans
