    java.lang.NoClassDefFoundError: com/smartgwt/client/data/DSCallback on server side

    Hi,

    I got this error when I try to get field value from DSRequest (Spring bean/datasource DMI). I'm using SmartGWT Power 2.5. If I add smartgwt.jar to the WEB_INF\lib, everything starts working. Is any dependency between server side isomorphic libraries and smartgwt.jar? I'd like to avoid adding 10MB to my WAR.

    Code:
    import com.isomorphic.datasource.DSRequest;
import com.isomorphic.datasource.DSResponse;

public class DlgWizardActions {

   public DSResponse updateDpaceInitParams(DSRequest request) {
      DSResponse response = new DSResponse();
      Long wizardId = (Long) request.getFieldValue(Application.PARAM_WIZARD_ID); //exception here
      return response;
   }
}
    Log:

    Code:

    Never mind, the problem was that we use Java constants defined in a Application class (client side)
