This blog will explain how to handle XML to JSON conversion in REST adapter. Here we will cover enhanced REST adapter settings to handle array – repeated segments.

REST adapter uses 3rd party Jettison library for JSON processing tasks. It is used for conversion of XML to JSON & vice-versa and sometime it does not correlate or take into consideration payload field properties as defined in a corresponding message type, but has its own optimization and type derivation mechanisms that are based on nature of the value of a processed XML document’s element rather than XSD schema of a processed message.

As a result, sometime conversion are not correct especially in case of XML element as an array.
