Accessing JCR from remote application (i.e. Hybris)

Hi,

I have written sling servlet to fetch DAM Asset from JCR Repository. Then retrieved InputStream from Rendition of an Asset, so that I can read an asset and write it to servlet response. I have attached servlet code. Code is working fine. When I hit URL http://localhost:4502/bin/testServlet?category=city browser redirects me to login page of CQ. After I enter credentials for login, browser displays an image which is returned from servlet response.

Can anyone please guide me how I can provide authentication in servlet itself, so that browser will not ask for credentials and will show image immediately after hitting URL?

I have also tried below code snippet but it gives me RepositoryException (Unable to access a repository with the following settings:
    org.apache.jackrabbit.repository.uri: http://localhost:4502/crx/server). 

String remoteURLLocation = "http://localhost:4502/crx/server";
repository = JcrUtils.getRepository(remoteURLLocation);
SimpleCredentials credential = new SimpleCredentials("admin","admin".toCharArray());
session = repository.login(credential);  

Please suggest best approach to achieve the same.

Thanks,

Manju

Hi,

I have tried below code

ResourceResolver resourceResolver = resolverFactory.getAdministrativeResourceResolver(null);
session = resourceResolver.adaptTo(Session.class);

But still when I access servlet with new browser (not the same browser where CQ session is available) it redirects me to CQ login page. 

How can I provide authentication details in servlet itself so that it will not redirect me to login page?

Thanks,

Manju

To access the JCR from an OSGi bundle - use the following code:

//Inject a Sling ResourceResolverFactory

@Reference
private ResourceResolverFactory resolverFactory;
 public String getCustomerData(String filter) {
 
Customer cust = null;
 
List<Customer> custList = new ArrayList<Customer>();
try {
           
    //Invoke the adaptTo method to create a Session used to create a QueryManager
    ResourceResolver resourceResolver = resolverFactory.getAdministrativeResourceResolver(null);
    session = resourceResolver.adaptTo(Session.class);

 

DO not use:

SimpleCredentials credential = new SimpleCredentials("admin","admin".toCharArray());
session = repository.login(credential);
