-_-||| HTTP error 413-FULL HEAD

hi, I encountered an error while passing a very long String (about 2000 chars) to jetty server through REST service:

com.ibm.team.repository.common.transport.TeamServiceException: CRJAZ0098I The "com.newteam.common.ISmarterService{/jazz/service/com.newteam.common.ISmarterService}" service failed. The server returned the HTTP error 413 with error text "FULL head".
