Subject: RE: [wsbpel] Issue - 11 - Partial Schema Compliance
Chris, An alternative approach - if you want full up validation based on business rules - is to call an OASIS CAM processor as a webservice via a WSDL definition - and get it to do the work. It appears to me you have two forks here - a) Simple lightweight local validation - works for just a few fields, strings, numbers, enumerated lists - easy stuff that schema can handle - where there is little or no variation in the structure of the content - can be done cheaply using schema, DOM and XPath. b) Serious structure validation - with lookups, rules, contextual checks, contextual structure variations, localization, and also input / output rendering: call a CAM processor - pass it the input - indicate the CAM template you want - (or that can be configured as part of the partner profile) - and it can do full-up validation and also contextual error responses - and return a new structure for you as output as needed, or the validated input. See the CAM specification from the TC website. Enjoy, DW. Chair OASIS CAM TC. ================================================================== Message text written by INTERNET:chris.keller@active-endpoints.com > I'd vote for the validation "only when dealing with external services". But in addition we should add a new function like bpws:validateVariable('x'). This could return a Boolean, which would be true if valid and false if not (or we could have it return a new bpel type, which gave more info on what was invalid). In this way users can build valid messages via assigns and then decide if and when they may need to test the data (e.g. they can put it in a switch with a throw if the data is invalid). But they should never receive or send out bad data so that validation should be mandatory. <
