Querying Adobe Experience Manager 6.4 JCR data

You can create an Adobe Experience Manager (AEM) 6.4 HTL component that queries data located in the AEM Java Content Repository (JCR). To query data, you use a javax.jcr.query.Query instance that belongs to the JCR Query API. This API supports both searching and querying operations. For example, assume that your AEM application tracks your organization’s customers. You can query the JCR to obtain a customer result set in which a digital marketer is interested.

In AEM 6.4, you get a session instance (required to work with the JCR API) by using a Sling method named getServiceResourceResolver().  The following code shows use of the more secure getServiceResourceResolver API call.

Map<String, Object> param = new HashMap<String, Object>();
param.put(ResourceResolverFactory.SUBSERVICE, "datawrite");
ResourceResolver resolver = null;

 try {
           
    //Invoke the adaptTo method to create a Session used to create a QueryManager
 resolver = resolverFactory.getServiceResourceResolver(param);
    session = resolver.adaptTo(Session.class);

This article creates the following AEM HTL component that displays data queried from the AEM JCR.
