Component Validation & Properties File

Question

hi
I have created a simple web-page using visual web framework where I m taking FName as input string..where i want to validate that user should not enter any number or a white space character..
I want to validate it using Regular Expression i.e. java.util.Pattern
     String merit=(String) getMerit_num().getSubmittedValue();
        Pattern pattern =Pattern.compile(text_pattern);
        boolean matcher=Pattern.matches(text_pattern,merit);
        if(matcher)
            setMsg_merit(msg_merit);
        }Above code checks that whether its a digit or not but how to check a white spce charcater with this?
Is it the right way? mean is there any other better way for it?
And how to edit Messages.Properties File?

Is it the right way? mean is there any other better way for it?I can't tell if the above code is correct, because you didn't show how text_pattern look like. If you're using Java 1.5 or newer, you could also use String#matches() instead of all those code lines. Just pass the text_pattern as parameter.
And how to edit Messages.Properties File?Just create your own, put it in the classpath and define it as <message-bundle> entry in the faces-config.xml. Specify in there any message key that you want to override from the default. If you don't specify it, then the default will be used.
