Getting a regular expression from application.properties

[Simon Matic Langford <si...@pcmsgroup.com>]

I have a regular expression for date formatting (don't ask!) in our
application.properties. This can
change depending on user locale. I am trying to get the following value
back:

^[0-9]'{'0,10'}'(,[0-9]'{'0,2'}')?$

However in MessageResources at line 346: format = new
MessageFormat(escape(formatString));

escape replaces ' with '', which means that my {'s and }'s don't get
escaped properly
and MessageFormat throws an IllegalArgumentException saying it can't
parse the expression.

Is there any way to persuade Struts not to do this escaping without
totally bypassing
it?

I am using Struts 1.1 and cannot upgrade...

Thanks

Simon

yes, then the app gets:

^[0-9]\''{\''0,10\''}\''(,[0-9]\''{\''0,2\''}\'')?$

all the escaping does is replace ' with '', which makes it a little hard
to stop
it as the comparison is done on a character by character basis...

Did you try escaping the single qoutes with a backslash?

^[0-9]\'{\'0,10\'}\'(,[0-9]\'{\'0,2\'}\')?$
