Hello All. I've got a soap service(which is also a seam component) with a method that returns a hashmap. Through debugging I know that my method is returning a valid set of java objects but from client code( Ruby and Java) all I'm getting is a null value. Other methods that return simple strings or return an array of Longs work perfectly. as far as my platform I'm running on jboss 4.2.1GA with Seam 2.0.0GA. here's the relevant server code. The first method is one that works incorrectly and the bottom two work: | @WebService() | @SOAPBinding( | parameterStyle=SOAPBinding.ParameterStyle.BARE, style=SOAPBinding.Style.RPC) | //@SOAPBinding(style = SOAPBinding.Style.RPC) | @Name("StudyServiceWS") | @Scope(value=ScopeType.STATELESS) | @Stateless | public class StudyService implements StudyServiceRemote{ | | //this is a test method that currently returns a null to the client | @WebMethod | public HashMap getHashMap( String key, String value) | { | HashMap m = new HashMap(); | m.put( key, value); | return m; | } | //this method works | @WebMethod() | public String echo( @WebParam(name = "echo")String echo) | { | return echo; | } | //this also works | @WebMethod | public Long[] getStudyIDs( String x500) | { | Long[] returnIDs = null; | UserHome userHome = (UserHome)Component.getInstance( | UserHome.class, true); | User user = userHome.findByInternetID(x500); | | ...... | | return returnIDs; | } | | generated
