Hi Keith,
There is no validation framework provided by Jersey.
Some developers are using the Bean Validation Framework. See the  
following thread:
http://markmail.org/search/?q=list%3Anet.java.dev.jersey.users+validation#query 
:list%3Anet.java.dev.jersey.users%20validation%20order%3Adate-backward 
+page:1+mid:3qhjvhnozilsuzmn+state:results
IIRC other developers may be using some AOP-based solutions to  
validate resource method parameters.
Hope this helps,
Paul.
