[jboss-user] [JBossWS] - problem with web method returning list

[patel_123]

hi
I am exposing ejb components as webservice.Initially i exposed one method as web method,that returns String.This works fine.Next i tried another method which returns array of objects.This leads to following error....

Caused by: javax.xml.rpc.JAXRPCException: org.jboss.xb.binding.JBossXBValueFormatException: Java value for XSD boolean type expected to be an instance of java.lang.Boolean or java.lang.Number. But the value is of type java.util.ArrayList
