Access to ApplicationResources.properties from Action class?
Hi all,
I'm pretty new to struts, and just started developing a fairly
simple app, however taking a bit beyond the standard example functionality.
I have a (probably) pretty simple question:
I'm in the perform method of the Action class, processing a form submit, but
want to
forward to different mappings depending on which button was pressed.
In the JSP I am using the ApplicationResources.properties file to create the
button text for the
different buttons, so now I need to access this text also to determine which
action to
take.
So how do I access the descriptions from the properties file in the Action
class?
my form:
-------------------
<tr>
<td colspan="5" align="right">
<html:submit styleClass="bodyform">
<bean:message key="button.cancel"/>
</html:submit> </td>
<td>
<html:submit styleClass="bodyform">
<bean:message key="button.edit"/>
</html:submit> </td>
<td>
<html:submit styleClass="bodyform">
<bean:message key="button.confirm"/>
</html:submit></td>
</tr>
-------------------
So what do I put at the ... in the following fragment of the perform()
method to
be able to get the textual value of the button.cancel and button.edit?
-------------------
String submit = request.getParameter("submit");
// Forward control depending on which button was pressed
if (submit.equals(...))
return (mapping.findForward("cancel"))
else if (submit.equals(...))
return (mapping.findForward("edit"))
-------------------
Thanks,
Martijn.

David,
Please clarify for me. I am trying use your application for validation and display
different error depending on a selected language. It is 05 release. Your
RegistrationAction.java or MultiRegistrationAction.java calls
Locale locale = getLocale(request);
but it is not used in the source code (directly). Maybe I am missing something. Your
have 2 properties files depending on the language. Does MessageResources use them?
Thanks,
Maya

MessageResources messages = getResources();
String message = messages.get(locale, "resource.key");
See the API docs for all of the different ways to
retrieve a message resource.

Re: Access to ApplicationResources.properties from Action class?

Hello,
I think that the best thing to do would be to not use the text of
the button at all. If you use the text you will need to change the
code as well if you decide to change the text on the button by
editing the property file. (And if you get internationalization into
the picture it will be even worse.)
I think the solution would be to have different names on the
buttons (using the 'property' attribute of the <html:submit> tag) and
check the button used by having properties for all the possible names
in the Form bean and see which property that is different from null.
(Or by doing a request.getParameter() as you do in your example, but
I like the automatic way better :-) )
The downside of that is of course that you need extra properties in the
Form bean class but I still think it will be worth it.
To come back to the original question I do not know how to do it
but I guess that it would be possible to find by checking the source
of the <bean:message> tag.

Mikael
