Creating AEM DAM component

Avatar

Level 4

Hi Friends

I am working on creating a DAM component in my project I was following the below url

https://helpx.adobe.com/experience-manager/using/aem-dam-image-components.html

can this example be followed in AEM6.1 as the document says it is for 5.5 and 5.6

When I use the same code snippet in my jsp.

I have my assets in dam/emitra/photogallery

let me know whether I need to mention my DAM asset path as dam.Asset or dam.emitra.photogallery

if I give as dam.emitra.photogallery I am getting assets

'dam.emitra.photogallery' not found

Logs for reference

qb----------->com.day.cq.search.impl.builder.QueryBuilderImpl@57e1389c

query----------->com.day.cq.search.impl.builder.QueryImpl@29b87af7

sr------->com.day.cq.search.impl.result.SearchResultImpl@60365b4f

path------->/jcr:system/jcr:versionStorage/ee/19/c6/ee19c692-acdd-4254-99dd-55fad6b4d050/1.0/jcr:frozenNode

rs------->JcrNodeResource, type=nt:frozenNode, superType=null

asset----------->null

 

Some one can help me

Regards

If you want to use QUeryBuilder code in a JSP in 6.1 - this works: 

<%@include file="/libs/foundation/global.jsp"%>
<%@page session="false" %>
<%@page import="com.day.cq.tagging.*,com.day.cq.wcm.api.*"%>
 
<%@ page import="java.util.*,
    javax.jcr.*,
    org.apache.sling.api.resource.*,
    org.apache.sling.api.scripting.*,
    org.apache.sling.jcr.api.*,
    com.day.cq.search.*,
    com.day.cq.search.result.*"
 
 %>
 
<%@page import="com.day.cq.dam.api.Asset"%>
 
<% 
SlingRepository slingRep = sling.getService(SlingRepository.class); 
Session session = slingRep.loginAdministrative(null);
QueryBuilder qb ; 
Map<String, String> map = new HashMap<String,String>();
map.put("type", "dam:Asset");
map.put("property", "jcr:content/metadata/dc:format"); 
map.put("property.value", "image/jpeg");
qb=resource.getResourceResolver().adaptTo(QueryBuilder.class);
Query query = qb.createQuery(PredicateGroup.create(map), session);
 
SearchResult sr= query.getResult();
String assetPath=null; 
 
 // iterating over the results
  for (Hit hit : sr.getHits()) {
      String path = hit.getPath();
      Resource rs = resourceResolver.getResource(path);
      Asset asset = rs.adaptTo(Asset.class);     
     assetPath = asset.getPath(); 
%>
<img src="<%= assetPath %>" />
<%

}
%>

I am going to try this code on 6.1 and report back the findings, This article was never tested on 6.1 as stated in the summary at the beginning.

Scott,

Any updated on AEM6.1 implementation for the above code.

YOu are correct - the code works on 5.x and throws an null exception on 6.x. We will update the code for AEM 6.

Found the issue - 5.x was referencing a rendition for that version.

On AEM 6 - change the line 38 to:

<img src = "<%= asset.getRendition("original").getPath()%>" ></img>

And Yes - when using the QUeryBuilder API - you can reference a path where your assets are located. See this AEM Doc topic: 

https://docs.adobe.com/docs/en/cq/5-6-1/dam/customizing_and_extendingcq5dam/query_builder.html

Update - DAM code works on 6 - still an issue with 6.1. Working on it

 If you are working on 6,1 - its recommended that you do coding a bit different from from 5.x JSPs.

Instead - write a Sightly component that uses QueryBuilder.  QueryBuilder will query for DAM assets and then Sightly displays the result set. See this community article to point you in the right direction:

Thanks For the support.

We implemented using custom carousel  below code for your reference

<%@page import="com.day.cq.tagging.*,com.day.cq.wcm.api.*"%>

<%@ page import="java.util.*,
    javax.jcr.*,
    org.apache.sling.api.resource.*,

    com.day.cq.search.*,
    com.day.cq.search.result.*,
com.day.cq.dam.api.DamConstants,
com.day.cq.search.result.*"
