please let me know how can json response. appreciated.

you can set messagetype application/json instead of application/xacml+json in outsequence , try.

<property name="messagetype" value="application/json" scope="axis2" type="string" description="messagetype"/>

also there no application/xacml+json message formatters , message builders shipped wso2 esb default. if need use these formats have write own formatters , builders , configure them in axis2.xml file.
