Regular expression help.

I'm trying to use a regular expression to obtain the contents of a text 
file say  between the start and end (which can occur many times in the 
file):

2003-03-07 17:20:33 [6] DEBUG:   type_name: deliver_sm
{
    many lines to follow.
}
2003-03-07 17:20:33 [6] DEBUG: SMPP PDU dump ends.



But the result doesn't seem to work, and will continue on until the end 
of the file.
Is there something wrong with my pattern ?  My pattern looks like this :

String pattern = "\\s*type_name: deliver_sm\\s*([^\\f]*)\\s*SMPP PDU 
dump ends.\\s*"
I'm using the Perl5Compiler. What can I do to correct the pattern ? I'm 
kind of new at this.
