Worklight does not support the out parameter in SQL adapters. See this question: IBM Worklight - How to get OUT parameter when invoking a stored procedure?

The question I linked you to also contains an answer providing an elaborate workaround if you wish the try it (basically, override Worklight and implement it in Java code).
