When I try reading JSON file from DAM using resolver factory I am getting null pointer.

 

Tried many ways. I am using servlet call.

Try reading it using service user. 
You can create a systme user by going to /crx/exlporer and then later assign the read/write permissions in /useradmin

 


Once you are done creating the user, try the resolverFactory code to get the resource resolver and then resource out of it.

Map<String, Object> param = new HashMap<>();
param.put(ResourceResolverFactory.SUBSERVICE, "serviceUser");
ResourceResolver resourceResolver = resolverFactory.getServiceResourceResolver(param);

Happy Coding!!


Thanks,

    Try using this, as we are accessing some file placed in DAM we do need a authenticated service user to do so.
