org.codehaus.jackson.map.JsonMappingException: Infinite recursion (StackOverflowError)

Question

I am trying out some very basic webservice. I get this exception everytime I try to return the Prtnr object.

Uncaught exception thrown in one of the service met         


        

Answer 1

The infinite recursion is due to the following: Class Prtnr contains Set prtnrGeoInfos and each PrtnrGeoInfo contains PrtnrGeoInfoId id which in turn contains Prtnr partner.

Thus, Prtnr -> PrtnrGeoInfo ->PrtnrGeoInfoId ->Prtnr, is causing a cyclic dependency which is a problem for Jackson when it is trying to do the POJO Mapping.

You need to remove this cyclic dependency to fix this exception.
