webservice nosuchmethoderror

Hi

I have a simple java app I develop on NDS.

This app calls an ABAP webservice to get a list of flights (BAPI_FLIGHT_GETLIST). The problem is that when I run my program I get

java.lang.NoSuchMethodError: com.sap.engine.services.webservices.jaxrpc.wsdl2java.BaseGeneratedStub._initParameter(Lcom/sap/engine/services/webservices/jaxrpc/wsdl2java/ServiceParam;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/Class;)V

I would appreciate any help in this regard.

Hi Sumit

No, I am afraid it was more than that.

The problem stem from discrepancy in versions.

The AS version was 7.09 whereas NWDS' version was 7.12.

Once I downgraded my IDE and recompiled everything, I was able to deploy and run my application in no time.

I trust this answer will help our fellow programmers.
