The setSbbContext code part:

public void setSbbContext(SbbContext context) {
    this.tracer = context.getTracer("JdbcExampleSbb");
    this.contextExt = (SbbContextExt) context;
    this.jdbcRA =  (JdbcResourceAdaptorSbbInterface) this.contextExt
                  .getResourceAdaptorInterface(JdbcResourceAdaptorSbbInterface.RATYPE_ID, "JDBCRA");
    this.jdbcACIF = (JdbcActivityContextInterfaceFactory) this.contextExt
       .getActivityContextInterfaceFactory(JdbcActivityContextInterfaceFactory.RATYPE_ID);
}

Issue Resolved, Thanks a lot for your help :-) I just change the JDBC DU old release to 7.0.11
