any suggestions please. not able hit url, , log input json.

this error comes when send xml payload application/json content-type header esb. best thing can here enable wirelogs , check http headers , payloads sent esb. enable wirelogs follow these steps,

• shutdown esb instance

• move onto $esb_home/repository/conf directory , locate log4j.properties file uncomment following line

  log4j.logger.org.apache.synapse.transport.http.wire=debug

• then restart esb instance again , send request

monitor esb console wirelogs follows

the symbol '>>' gives contents written esb , '<<' gives contents written out of esb.

also doubt curl command, hence sample curl command given below.

   curl -v -d @test.json -h "content-type:application/json" http://localhost:8280/rest/api/createissue
