Merged idea

This idea has been merged into another idea. To comment or vote on this idea, please visit ZCEE-I-134 z/OS Connect JSON Parser needs to handle large numbers and not round numeric values.

An option is needed to prevent JSON parsing/rebuilding when returning JSON from an application Merged

When an application returns a JSON string to z/OS Connect, the JSON is passed to the IBM JSON parser for analysis and validation. Subsequently the JSON string is rebuilt. This is an overhead and any limitations of the IBM JSON parser (such as the size of numeric fields) may cause error (which the application is not informed about). An option should be available when defining a service to tell z/OS Connect not to valiate/rebuild the JSON.

    The example use case probably needs clarification. If the application returns a JSON file that is a 'large' number (i.e. that has too many digits in it for the IBM JSON parser to handle) then either an error is raised or the number is truncated and rounded and converted to a floating point value.

    For example if the JSON string has "NUMFLD":123456789012345678901234567890

    The IBM JSON parser will raise an error and the 'user' will get a lot of error information. (Note that the application is not made aware that this has occurred)

    If the JSON string has "NMUMFLD":1234567890123456789012345678.123

    the IBM JSON parser will treat the number as valid, but will change it to 1.2345678901234569e+27 (Note that it has been rounded and changed from a standard number with 3 decimal places to a floating-format number)
