The "Not a valid AllXsd value" Error Message
I was recently testing a web service method using SOAP UI and received the following error in regard to one of the method's parameters, which happened to be a date/time value: "The string '2010-09-23 10:00:00 AM' is not a valid AllXsd value." The solution was to format the value in YYYY-MM-DDThh:min:seconds.milliseconds format. For example: 2010-09-23T10:00:00.0000 Use leading zeroes for 1-digit hours. Example: 2010-09-23T09:00:00.0000 In my environment, the milliseconds were optional.
