Web Dynpro LinkageError when calling connection.retrieveNative()

91 Views

Hi,

This problem is confusing me. I have a Web Dynpro for Java project that is making a connection to MDM. The code is very simple but I cannot get round this exception

LinkageError: Class com/sapportals/connector/connection/IConnection violates loader constraints

Which is occuring when the connection.retrieveNative() method is being called.

If anyone has any idea what this could be, please let me know. I will be very grateful. The code I am using is below.

IConnectorGatewayService cgService = (IConnectorGatewayService)WDPortalUtils.getServiceReference(IConnectorGatewayService.KEY);

IUser user = UMFactory.getUserFactory().getUserByLogonID(loginId);

ConnectionProperties prop = new ConnectionProperties(user.getLocale(), user);

connection = cgService.getConnection(alias, prop);

INative nativeInterface = connection.retrieveNative();

Many Thanks

Gary
