             catVersion1 = catalogVersionService.getCatalogVersion("cms_Catalog", "Staged");
         System.out.println(catVersion1);

         DynamicProductModel dynamicProductModel = new DynamicProductModel();
         //dynamicProductModel.getName("productName");
         dynamicProductModel.setDescription(productDescription);
         dynamicProductModel.setCatalogVersion(catVersion1);
         dynamicProductModel.setGeneratedHtml(productHtml);
         dynamicProductModel.setBundleReference(bundleReference);
         dynamicProductModel.setControllerScript(controllerScript);

         DynamicProductModel dynamicProductModelCreate = modelService.create(DynamicProductModel.class);
         // CatalogVersionModel
         CatalogVersionModel catalogVersionModel = new CatalogVersionModel();
         // catalogVersionModel.setCatalog(new CatalogModel().set);

         // dynamicProductModel.setCatalogVersion(new CatalogVersionModel()
         // );
