The reason you can use a space is because you have . in there which does
NOT mean the character . but 'anything', that is matching your spaces.
Having a - in a character class un-escaped is definitely incorrect
syntax as it's the range opperator for things like A-Z and a-z. The
& thing is wrong because character classes only match individual
characters and not sequences of characters. The reason your RE is not
working right is because it has syntax errors in it. You need to fix
those before it will work reliably. The class in my reply you quoted
below is more correct to what you have ATM.
If you want to get this to work my advice would be to simplify it first,
get the basics working and then start adding in suport for more special
characters, testing as you go.
As I read your RE the pattern in English would be "A letter followed by
any amount of letters, nubmers, spaces, new line characters and some
allowed special characters". Hence the following would be my starting
point and I would then start adding in the special characters, being
careful to escape where needed:
<var-value>^[a-ZA-Z][\w\ \r\n]*$</var-value>
That will allow all letters, numbers, spaces, newline characters after the
first character which must be a letter. You can then add the special characters
you need. You will definitely need at least the following:
<var-value>^[a-ZA-Z][\w\ \r\n\.\-\(\)]*$</var-value>
Note that you MUST escape . and - or you will be getting a different RE
than what you think you are getting. If you put in . without escaping it
it means "anything" so your RE will still allow through the special
characters you think you are blocking.

Bart, the mask that I have been using is
<var-value>^[a-zA-Z]{1}[a-zA-Z0-9\n_,;?!;:[EMAIL

And this allows me to use spaces, & , - and other special characters
mentioned above. Just that \n does not work here.

Hi Sahil,
I'm 90% sure the problem here is that some more of the special characters in
your large character class need to be escaped out. Thing is I can't find any
details of the syntax for REs in the struts validator docs so I'm not sure
exactly which ones. At a guess I'd suggest the following:
<var-value>^[a-zA-Z]{1}[a-zA-Z0-9\n\r\
_,;?!;:[EMAIL PROTECTED]/\\()&$%#*+=\-]*$</var-value>
The character class only matches individual characters so & should not
be intere like that. As long as &, the letters a, m and P and ; are matched
then & will be fine. . is a special character in it's own right so to
represent an actual fulstop you need \. and - is certainly a special
character within a character class so it definitely needs to be escaped.
Your RE was also not allowing the space character and depending on your OS
new lines can also use the \r special character so I added \ (slash followed
by a space) and \r to the class.

The current mask that I am using is:

<msg name="mask" key="message.mask.displayname" />

<var-name>mask</var-name>

<arg1 name="maxlength" key="${var:maxlength}" resource="false"/>
<var>
<var-name>maxlength</var-name>
<var-value>250</var-value>
</var>
</field>
And if I input some text and along with that I press the Enter Key I
get Validation Error message that I have mentioned in my
ApplicationResources.properties file.
Eg: In the text box I gave the following:
Recommended (and then pressed enter)
And Verified.
When I entered the above text in the Text Box it gave the validation
error message.

Can you show me the current version of your mask and a sample of an
input it is rejecting?

Thanks Bart,
Yes, what you said was right, so I have changed \ to \\ to match \.
But still I am unable to allow \n in my Validation.

OK, so your Regular expression is trying to match everything between
the start (^) and the end ($) of your input and no where in it do you
allow a new line character, hence it is failing. You need to allow \n
in which ever part of the RE you are happy to have new lines appear in.
At a guess I'd say you probably want them in the second character
class. What I do also notice is that you seem to have some un-escaped
special characters in your second character class. The most obvious
one is a single \, that will not match \, to match \ you need \\.
Hope that helps,
Bart.

Hi,
I have used Masking in Validations. I have a text area in which I
have only restricted some special characters. But still if I press
Enter while adding some text there I get an error message.
Can anyone tell me how to allow ENTER in mask.
Thanks
