json - Returning specific date format with Jackson -

i trying return date on json object specific format: format:

"lastmodified": "2015-08-04t13:09:15.000-07:00",

i have custom objectmapper this:

result.setdateformat(new iso8601dateformat()); 

but result: "lastmodified": "2015-08-04t20:09:15z"

any ideas how change it? using:

<dependency>   <groupid>org.glassfish.jersey.media</groupid>   <artifactid>jersey-media-json-jackson</artifactid>   <version>2.22.1</version>   <scope>runtime</scope> </dependency> 

and before used older version of: org.codehaus.jackson

update: after adding line:

result.configure(com.fasterxml.jackson.databind.serializationfeature.         write_dates_as_timestamps , false); 

and removed:

result.setdateformat(new iso8601dateformat()); 

i got result: "lastmodified": "2015-08-04t20:09:15.000+0000", still not want.

this right format:

result.setdateformat(new simpledateformat("yyyy-mm-dd't'hh:mm:ss.sssxxx"));
