Hello: I've created an OpenAjax registry for Apache XAP:
http://www.openajax.org/member/wiki/Registry_Candidates_for_Apache_XAP OpenAjax registry is a registry for Ajax offerings, especially those who have global variables and need to avoid conflicts with other Ajax libraries. The only global variable I registerd for XAP is "xap" - please reply or modify the registry wiki page if there are other variables need to be registered. ---Coach
