Tried this http://localhost:4504/content/dam/we-retail/en/experiences/arctic-surfing-in-lofoten/arcti c-surfing-in-lofoten.infinity.jsonand it worked!!.Had already set up content fragments as the adobe document.

Hi Arun,In the aem 6.4 jar, the package "com.adobe.cq.caas.impl.feature.ContentServicesFeatureFlag", is not present, so as to enable the content service. As per the adobe documentation, aem 6.4 supports content services without any other feature packages. Would appreciate some advice on this.
