Hi

I'm trying to create a login interceptor.

When a login form is submitted, I got the following exception:

com.opensymphony.xwork2.interceptor.ParametersInterceptor setParameters
SEVERE: ParametersInterceptor - [setParameters]: Unexpected Exception
caught setting 'button.login' on 'class
com.opensymphony.xwork2.ActionSupport: Error setting expression
'button.login' with value
'[Ljava.lang.String;@(protected)'


What does this exception means?

A param called "button.login" means the ParametersInterceptor has to
call getButton().setLogin(val).

If you don't have a getButton() method, or getButton() returns null, an
exception like this occurs while trying to set the parameter.

The "button.login" is a key in i18n properties file, and it is suppose
to retrieve the label for a button.

I suspect this problem could be the interceptor statck I configured,

    <interceptor-ref name="servlet-config" />
    <interceptor-ref name="params" />
    <interceptor-ref name="login" /> // my interceptor
    <interceptor-ref name="prepare" />
    <interceptor-ref name="chain" />
    <interceptor-ref name="model-driven" />
    <interceptor-ref name="fileUpload" />
    <interceptor-ref name="static-params" />
    <interceptor-ref name="params" />
    <interceptor-ref name="conversionError" />
    <interceptor-ref name="validation" />
    <interceptor-ref name="workflow" />


Is it OK if my login interceptor is configured after the params interceptor?

It depends what your interceptor is trying to do...
At the moment, I still think params is trying to call
getButton().setLogin(val) on your ACTION (prior to execution of your
login interceptor).
I presume your interceptor is going to check the params or session and
redirect if not authenticated, which is fine, but with your stack the
params interceptor will attempt to write to the ACTION first.

I still suspect your JSP/html includes a field with NAME "button.login"
and params is throwing the exception due to getButton(). You can test
my theory by giving the field a different name (eg. key="button.login"
name="login") that won't cause an error.

Hmmm ... my login.jsp now looks like this,

<s:form action="index" method="post" validate="true">
<s:textfield name="username" key="user.username" />
<s:password name="password" key="user.password" />
<s:submit name="login" key="button.login" />
</s:form>


When the login button is pressed, the following exceptions are shown
in the console,

com.opensymphony.xwork2.interceptor.ParametersInterceptor setParameters
SEVERE: ParametersInterceptor - [setParameters]: Unexpected Exception
caught setting 'login' on 'class
com.opensymphony.xwork2.ActionSupport: Error setting expression
'login' with value '[Ljava.lang.String;@(protected)'

com.opensymphony.xwork2.interceptor.ParametersInterceptor setParameters
SEVERE: ParametersInterceptor - [setParameters]: Unexpected Exception
caught setting 'password' on 'class
com.opensymphony.xwork2.ActionSupport: Error setting expression
'password' with value '[Ljava.lang.String;@(protected)'

SEVERE: ParametersInterceptor - [setParameters]: Unexpected Exception
caught setting 'username' on 'class

That looks fine. Do you have an action called index in the default
namespace? It's calling ActionSupport which is the default/fallback
action under some circumstances.

You may need to go back to the default interceptor stack to isolate
what's wrong. Or post the package from struts.xml here.

PS. [Ljava.lang.String;@(protected).

Actually, I'm following the tutorial described at
http://www.vitarara.org/cms/struts_2_cookbook/creating_a_login_interceptor.

May I know which file that is showing the Struts2 default interceptor stack?

Thanks for your help!

The referenced tutorial looks fine.

I'd remove the interceptor first and ensure everything works without
it. (confirm that you can post to the index action)
Then add the login and see if that causes the exception.
I'd probably insert the login interceptor before the param interceptor
myself as this particular example doesn't need to write to the action on
a failure.

struts-default.xml is available on this page:
http://struts.apache.org/2.x/docs/interceptors.html

Since printing would be platform depending there seems
to be no universal answer.

If you are programming for IE clients I would suggest

use window.print
or  window.document.execCommand('Print', , );

Encapsule it in an own Javascript function (for how
just google "javascrpt print" or refer to a JS board)
perhaps with an id as param (so you can print just
specific named parts of your page)

And call your function in the onclick of a nice
button...

Hi All,

I have a problem when creating the action of a form: this form is generated
dynamically using ajax and javascript depending on how the user fill in the
form. In this form there are checkboxes, comboboxes and textfields (a
variable number). And I don't know how to pick the values of each element of
the form.

Here is some code of the form:


<%@(protected)" %>

<html>

 <head>
   <title>ARS - Is Available Form</title>
   <s:head theme = "ajax"/>
   <link href="<s:url value="/css/mainstyle.css"/>" rel="stylesheet"
type="text/css"/>
   <link rel="STYLESHEET" type="text/css"

   <script language="javascript" type="text/javascript">
     // on click -> disable/enable the jobID textfield
     function insertJobID()
     {
       if (document.formreservation.jid.disabled == true)
       {
         document.formreservation.jid.disabled = false
       }
       else
       {
         document.formreservation.jid.disabled = true
       }
     }
     
     // onkeyup -> create a DIV for each service
     function addDivsServices(event)
     {
       divservices = document.createElement('div');
       divservices.id = 'divservices';
       divservices.style.border = "solid #00bfff 3px";
       divservices.style.padding = "5px";
       (document.getElementById('formreservation')).appendChild(divservices);
         
       for(i = 0; i < numS; i++)
       {              
         //THE DIV OF THE SERVICE -> name: 'divservice' + i
         divservice = document.createElement('div');
         divservice.id = 'divservice' + i;
         divservice.style.border = "solid #00cd00 3px";
         divservice.style.padding = "5px";

         cbx = document.createElement('select');
         cbx.name = 'tor' + i;
         
         opt = document.createElement('option');
         opt.value = '1';
         opt.text = '1';
         cbx.appendChild(opt);
         
         opt = document.createElement('option');              
         opt.value = '2';
         opt.text = '2';

Can somebody help me?

Than you!!!

Sent from the Struts - User mailing list archive at Nabble.com.

Is there anything alternative (apart annotation) to place validation
xml for the action method in the same package of the action classes?
I don't like to place .xml in the same directory of the .java
Any idea (apart annotation)

thanks.

Hi,

Has anyone been able to put dwr 2.0 working with struts 2.0.11 ajax validation?

Obvious facts are like secrets to those not trained to see them.

I want to edit an entity, i.e. a Message
i would set the .jsp field this way

<s:textfield name="message.title" />

on the MessageAction i would have a "edit" method that takes the
messageID and then call the business service to load the Message
object, so in the .jsp the file the textfield are loaded with the
current value.
when I submit the form, Struts2 will try to call
getMessage.setTitle("...") and so on, and it try to instatiate a new
Message object.
My idea is to create the object (loading it from hibernate calls on
the business service) in the prepare method, in this way when struts
will call getMessage.setTitle, it will set the new values on the
object loaded from the DB.
My worry is that this idea rely on the fact that the prepare
interceptor is called before the parameters interceptor.
What you think?
any better idea?

thank you.

There is no such thing. Do you need WYSIWYG? Are you looking for JSP
etc. awareness? Do you feel comfortable editing markup by hand? What are
your target DTDs?

Emacs, hands down.

Maybe not the best, but very good -> MyEclipse

The best tool to develop a html page is clearly a web designer paired
with a html producer.

Ah ah yes vi is probably the "best" ....
But if you need some more sophisticated like a WYSIWYG supporting more
than one DTD you can try AMAYA (www.W3C.org).

Now seriously, Mohammed, your question is too generic.
Do you need a WYSIWYG editor? Do you need to use it in your
application (i.e. using a Javascript editor)?

Antonio

I have a question about using OGNL PropertyAccessors. We have an object on the
value stack that we expose to JSP pages that does not have standard JavaBeans
getter/setter methods. From what I can tell, this leaves us 2 options. We can
either call the getter methods explicitly via OGNL method calls in the pages, or
we can wrap the object in a JavaBean-like object. The second option is
unworkable in all but the simplest of cases when you realize that the method
calls can themselves return another object that needs to be wrapped, or even a
collection of them. So we've been using method calls in the pages (yeah I know).

Reading through the OGNL docs, it seems that what we need is a PropertyAccessor
that knows how to operate on our object. So we implemented one, and attempted
to register it by placing this in our struts.xml:

<bean type="ognl.PropertyAccessor" name="class.we.need.access.to"
class="our.property.accessor.PropertyAccessor"/>

Unfortunately it doesn't work. Can someone tell me what we're doing wrong, or
even if what we're trying to do is possible? Thanks!
