Re: Error Message for Struts Validation
I've never used the <msg> attribute myself, but I think when you do, you
need to specify the key, and a name attribute for which validation the
message applies to. So in your case it would be:
<msg name="required" key="request.page" />
You may also need to specify a bundle and resource attribute, but I
don't think so in your case.
The error message you are seeing (null is required) is from the default
error message. When you use the default error message, you need to
specify replacement values for the error message template. If you look
in your application.properties, you should have a bunch of errors.XXXX
lines, for each standard validator. For example, you should have a line
like:
errors.required={0} is required.
for the required validator. The {0} is what needs a replacement. To
define it in your validator, you use:
<arg0 key="request.page" />
OR (for struts 1.2.x)
<arg key="requst.page" position="0" />
In these cases though, request.page should be defined in
application.properties as:
request.page=Page
then, when the error prints, it will print as "Page is required."
For me at least, this is a lot more handy than using <msg>, because you
can use the same label to print out the prompt and the error message.
Hopefully I explained this well enough...
