Hi Thomas, I am sorry, I couldnt get back to you on this earlier. Anyways, there is no jaxrpc-mapping.xml in the ear. There is a file named TradeServices_mapping.xml and here is what the file lists for getMarketSumary: <service-endpoint-method-mapping> <java-method-name>getMarketSummary</java-method-name> <wsdl-operation>getMarketSummary</wsdl-operation> <wrapped-element/> <wsdl-return-value-mapping> <method-return-value>org.apache.geronimo.samples.daytrader.MarketSummaryDataBeanWS</method-return-value> <wsdl-message xmlns:wrvm="http://daytrader.samples.geronimo.apache.org">wrvm:getMarketSummaryResponse</wsdl-message> <wsdl-message-part-name>getMarketSummaryReturn</wsdl-message-part-name> </wsdl-return-value-mapping> </service-endpoint-method-mapping> Please let me know if I am missing something here.
