textblock java validation

The_Bullman

I have a .jsp page with a textblock and I want to validate that block so it only contains alphanumeric characters plus spaces and also the carriage return(multilines).

Is it possible to convert the textblock into a String? I also have regular textboxes and that was no problem I'm just wondering if the return key will effect it at all?

How would I go about validating the carriage return. At the moment i have the textblock being made into a String and I'm using an array of chars to check each character to see if it is alphanumeric or a space. Is there a unicode character for hitting return or whatever it's called. I've tried a few things and I'm not getting it working

Or am I going about this arseways as usual :rolleyes:

Thanks for your help

System.getProperty("line.separator"); should return a string with the newline char in it.

Check for '\n' (newline) and '\r' (return).
