Query params check

[Dev1 <de...@gmail.com>]

Hi all,

I have a CXF REST WS URL that supports unknown number of query parameters.
I get the query paramters from  uriInfo - @context uriInfo.

The system requires that some of the query params cannot be not empty => the
key and the associated value cannot be empty. 

I can programatically check for non-null key and value. But I want to avoid
this approach and see if there any other approach in CXF.

Thus, is there a way in CXF to restrict the REST WS user to always send
non-empty values in the *key* and *value* of a query param? 

Example - If this is one of the query parameter that is being sent in the
url   -  useName=xyz
then both the *key* and the *value* *cannot be empty. *

Hope to know your input.

Thanks in advance.

Hi

If you had individual parameters typed in the signature then it would be 
simplere to do, using primitive types where possible, example, 'int', or 
introducing custom types and validating them with ParamConverter would 
do, but it is not possible in the unbounded number of parameters case, 
given that you bypass it by directly interfacing with UriInfo

Cheers, Sergey
