I am new to camle, I am reading the message from the IBM queue and
implementing camel dozer but getting null pointer exception. Appreciate
yourhelp
I have the following endpoint,
from(DOMAIN_MAPPING)
.routeId("domainMappingLogger")
.to("dozer:transformOrder"
+"?mappingFile=PartnerTransaferToTransactionMapping.xml"
+"&targetModel=PaymentTransaction")
.to(JSON_MARSHALLER);
Placed the dozer configuration,
