Hi Dale & Greg,

Thanks for all your discussion.

Yes, my validation step know what the result page should be (I mean the logical name of the result page), why I said it returning to the "input" that is because the workflow interceptor always return to the logical name "input" when there is error, that is why come to this idea to replace the value of "input"

Well, if I remove my validation code in the validate() method and put it into execute() method, then I can easily control which logical name to be return, but I thought that is not a good way to do that right?

There must be other way to solve this kind of validation problem, what I call this wizard validation, I think it is quite common in many web project.
Like in my case, create employee wizard, it break into 5 pages and handle by CreateEmpAction, I can use Greg solution 2, but then I need to create CreateEmpAction1, CreateEmpAction2, etc, thats not look so tidy to me.

Hopefully someone done this before can give me some light.

Regards
Louis

Thanks for let me know another struts2 book, have a quick look in it, didn't found any good tip to solve my problem.

Regards
Louis

And of course "PRODUCTIVITY TIPS" -> "Use Pattern Matching Wildcards in

            Use Pattern Matching Wildcards in Configurations

Action configuration files are somehow able to grow to
extremely large at incredible speeds. On way to combat this
phenomenon is to use pattern matching. Pattern matching works
by defining one or more patterns that URLs will conform to.
An example will be an easy way to see how things work. Let’s
say that the URLs in your web application always follows the
pattern “/{module}/{entity}/{action}.action”. This is a common
pattern;     examples      would     be     the   URL’s
“/admin/User/edit.action”,      “/admin/User/list.action”   and
“/admin/User/add.action”.

The class configuration is such that there is a Struts2 action class
with the name “{entity}Action”, and each {action} is method on
the action class. All the results from invoking the action’s
methods will result in either the update page for the entity being
displayed, or a list of all the entities being displayed.

For our example, the “struts.xml” configuration will look like
this:

*<action name=”*/*/*” method=”{3}”
      class=”com.infoq.actions.{1}.{2}Action”>
   <result name=”view”>/{1}/update{2}.jsp</result>
   <result name=”list”>/{1}/list.jsp</result>
</action>*

Each asterisk in the actions name is a wildcard. In the example,
only asterisks are used – but this need not be the case. For
example, say you wish to map all entity view actions together.
Something like ‘name=”/*/View*”’ would do the trick. Token
identifiers, {1}, {2}, etc., are then used to obtain the text values
harvested from the wildcards (where the numeric value
correlating to the position of the asterisk, ascending from left to
right).

In the “struts.properties” configuration file (or using the constant
tag in the “struts.xml” configuration file) you need to ensure the
following property is correctly set:

struts.enable.SlashesInActionNames = true

This property allows slashes in the name of the action. Struts2’s
default configuration is to not have slashes in the action name,
instead using packages for namespace separation.

Finally, there is no shortcut if you are providing validation and
conversion property files rather than using annotations. We’ll
talk about this more in following sections. Each needs to
contain the full name of the action, along with the necessary
extension: i.e. “edit-validation.xml” and “edit-conversion.xml”
for the original example, in the “com.infoq.actions.admin”
package.

While this might not be a "good way to do that," it's what I would do and in
fact have done.

I occasionally have to do validation in the execute() method but always
prefer to do declarative validation with annotations wherever possible since
it is so much simpler and cleaner. This means all my actions have to be able
to handle an 'input' result. Since 'input' result is the standard for
validation errors you should be prepared for it as the next programmer who
works on your code may add a validation() method or add validation
annotations.

@OP: If you know which page# in a wizard sequence to return to and use that
page# in the jsp name then you can make that page# available with a
getPage() method and do this:

  <result name="input">/xxx/MyWizardPage${page}.jsp</result>

It does mean you would need to have a jsp page naming convention that
includes the page#.

Hi,
I am using Struts 2.0 and I am not able to display the action errors in
my JSP.

Action class code :

if( ( getSelectedlocation() == null ) || getSelectedlocation().compareTo(
"" ) == 0
                          && ( (getLocation() == null ) ||(
getLocation().compareTo( "" ) == 0 )))
                    {
                          mLog.warn( "Location not
specified. Added Error message" );
                          addActionError( "Please specify a
Location for the message . " );
                    }


JSP code :

<tr>
  <td align="left" valign="top"><p><s:actionerror id="err" /></p></td>
</tr>


The error is added successfully as i can see from the logs but it is not
getting displayed on the JSP ..any pointers ?


Thanks,
Kavita

Re: <s:actionerrors> not displaying errors!






My first guess would be that you are not properly dispatching back to
your input page. A closer look at your struts.xml would clarify this,
though.
