Re: [Re: [configuration] specify a regular expression as string property]

[Oliver Heger]

If you use a properties file, you will have to double the backslash so 
that it is recognized by java.util.Properties. Single backslashes are 
interpreted as the beginning of an escape sequence. So you should have 
something like
biz.objects.brand.regex=.{0\\,30}

Have a look at the JavaDocs for the load() method of 
java.util.Properties. (I ran in the same trouble once when I tried to 
define windows pathes in properties files.)

Sorry guys, that doesn't work either :-(

I had tried that before; and tried it again:

biz.objects.brand.regex=.{0\,30}
Object o = config.getProperty("biz.objects.brand.regex");
logger.info ("REGEX " + o + " " + o.getClass());
Message: REGEX [.{0, 30}] class java.util.ArrayList

Yes, you are right. A backslash should do the trick.

The PropertiesTokenizer lets you escape commas with a backslash 
('\'). So
the getString() should return a regular expression string with the 
commas,
right?

So have you tried
first.name.pattern=.{0\,30}
