Your syntax is not correct as umarshalling of a jackson stream (coming from
the HTTP request) will return a HashMap. To access to this value using the
simple language, this syntax has to be used : simple("${body[code]}")
Example :
<route streamCache="true">
<from uri="
http://gateway.marvel.com/v1/public/comics?dateDescriptor=nextWeek&ts=987&apikey=97f295907072a970c5df30d73d1f3816&hash=abfa1c1d42a73a5eab042242335d805d
"/>
<log message=">> Response received : ${body}"/>
<unmarshal>
<json library="Jackson"/>
</unmarshal>
<log message="Attribute code : ${body[code]}"/>
<log message="Attribute status : ${body[status]}"/>
<log message="Attribute stacopyrighttus : ${body[copyright]}"/>
<log message="Attribute title : ${body[title]}"/>
</route>
