I cannot believe I missed that, my reports showed how obviously it was
creating singletons and never configured it not to. Thanks for the
information, resolved the problem within minutes of reading your response.

Thanks again!

My guess is that using an action extension of .html creates a conflict
with the Dojo template resources, which are .html files. If you look at
your access logs (or use Firebug to see what XHR requests are being made
during page rendering), you'll see what I mean.

The easiest thing to do is pick a different action extension (maybe .htm
or .xhtml). If you really need to be able to use .html as the action
extension, you'll have to figure out how to prevent Dojo template
requests from being treated as action requests.

Hi,

I don't know why you use such generic action class? And as I know OGNL
support generics and it will try to convert to given type without
TypeConversion

Try to change order of your interceptors as below

      <interceptor-stack name="contribStack">
         <interceptor-ref name="paramsPrepareParamsStack"/>
         <interceptor-ref name="autoLogin"/>
      </interceptor-stack>

How does your case differ from the example on the Type Conversion page
you referenced? It seems to me you're trying to do exactly what that
page says you can't?

Ahhh, that's the piece I missed. Seems like that should work, but I

Your best bet is to zip the two lists together into a map and provide a
getter on your form bean for that map. Failing that, you'll need to
iterate one of the lists (using c:forEach or logic:iterate) and handle
dereferencing into the other list explicitly. That might look something
like this (untested):

 <html:select property="xxx" ...>
  <logic:iterate id="val" indexId="idx"
     name="employeeForm" property="emplyeeNoList">
    <option name="xxx" value="${val}">
     <bean:write name="employeeForm"
        property="employeeNameList[${idx}]"/>
    </option>
  </logic:iterate>
 </html:select>

I know some containers support this, but it is container-specific

Agreed. Other options include a web service or other RPC mechanism, a
shared database, serialization to/from a shared disk location, etc. In
all cases you will need to be able to serialize the data you want to
pass and 're-hydrate' it on the other end.

Why not just validate all fields with type="requiredstring" and set
short-circuit="true" on them? Wouldn't that do what you want? See the
Short-Circuiting Validator section of the validation docs [1] for more
details.

Hi all,

If the end-user input wrong date-type (eg., date format is incorrect, or for
'number of people' he types 'Q') the 'input' is fired and it shows the error
message.

I do that with the 'return input' and the jsp page (this is ajax-id) looks
like this:


<%@(protected)" %>

udpate Fail<BR>
<s:fielderror />


the problem is that the user see something like this:
Update fail:
Invalid field value for field "Car.returnDate".

obviously returnDate is a field name in Car (that's great for the
developers); but my question is this: How can I show a nice understandable
error message such as: 'error with car return date'


thanks for any pointers
* once again, this is only when the data-type is incorrect.

Type conversion errors are added separately from validation errors.

Among the options is to remove the conversion error interceptor from your interceptor stack and use only the validation errors.

Hi Al,
Just another variation I use where the useragent requires javascript:
authenticate the user and generate a token; the token doesn't contain
any sensitive data;
the token is saved in a cookie and included in all requests (as cookie,
header or param)
an s2 interceptor checks the token is matched to an authenticated user.
it injects relevant details to actions
    (eg. a store maps tokens to users; server-side manages expiry,
concurrent logins etc)

It's not as fast as encoding login information in the cookie but it
can't be broken. I use the same method to sign XHR requests.

If the user has checked the "remember me" box the javascript gets the
token from the cookie and resumes using it. The server it knows not to
invalidate that token.

Vulnerabilities:
- The token should be unguessable to minimize forged requests;
- as javascript is inscecure, tokens can be stolen from the cookie
(eg. by an advertisement, XSS)

I wrote the above as an S2 plugin. The only problem with releasing it as
a plugin is that the "service that checks tokens" can't be
Xwork'@(protected)
spring or guice) due to its potential external dependencies (eg. an
EntityManager). The same plugin also allows me to apply roles to action
methods (jsr-250).

If the filename contains spaces it needs to be in quotes (eg.
filename="${fileName}") The result does not encode the string for the
disposition header in any way.
Have a look at the HTTP header of your response to see if the full
filename is there.
