Here is my api. I just use the omdbapi to give an example.

<?xml version="1.0" encoding="UTF-8"?>
<api context="/omdbapi" name="omdbapi" xmlns="http://ws.apache.org/ns/synapse">
    <resource methods="GET" uri-template="/*">
        <inSequence>
            <send>
                <endpoint>
                    <address trace="disable" uri="http://www.omdbapi.com/"/>
                </endpoint>
            </send>
        </inSequence>
        <outSequence>
            <datamapper config="gov:datamapper/omdbapiConfig.dmc" inputSchema="gov:datamapper/omdbapiConfig_inputSchema.json" inputType="XML" outputSchema="gov:datamapper/omdbapiConfig_outputSchema.json" outputType="XML"/>
            <respond/>
        </outSequence>
        <faultSequence/>
    </resource>
</api>

If you are trying to map JSON-> XML, you need to specify in the Data Mapper Mediator configuration. Make sure you set the input type as JSON.

And there have been beta2 release on wso2 esb. So try using beta2 packs for esb runtime and tooling . Use the latest pack and try.
