Hi All,

Using JCR API i want to fetch the value of thumbnail image of a Asset. 

Purpose.

I am trying to display the thumbnail image of a Book in the main page and on click of it i will display the complete details including the main image  of the Book.

 

I tried to fetch the data from under imagenode/rendition folder.

 

Thanks in Advance.

Try:

Resource resource = resourceResolver.getResource("/content/dam/Rental/prod1.gif");

Notice the / in the beginning of the resource path.

Tried in the following way

       ResourceResolver resourceResolver = resolverFactory.getAdministrativeResourceResolver(null);
        Resource resource = resourceResolver.getResource("content/dam/Rental/prod1.gif");
        Asset asset = resource.adaptTo(Asset.class);
        Rendition thumb = asset.getRendition("cq5dam.thumbnail.48.48.png");

 

getting a null pointer exception in line 3 (Asset asset = resource.adaptTo(Asset.class);)

Image  is available in the Asset able to access the metadata using JCR API.
