Issue with Creating Content Fragment Programatically

[niteshsoni21]

Hi Team,

There is a requirement where we need to create the AEM fragment programatically in AEM6.4.2 version.

Based on the document (Customizing and Extending Content Fragments ) , we are using the below code to create Content Fragment

Referred Code :

Resource templateOrModelRsc = resourceResolver.getResource("...");

FragmentTemplate tpl = templateOrModelRsc.adaptTo(FragmentTemplate.class);

ContentFragment newFragment = tpl.createFragment(parentRsc, "A fragment name", "A fragment description.");

The code is as below:

String parent = "/content/dam/cwb-poc";

Resource templateOrModelRsc = resolver.getResource("/conf/Test-Configuration/settings/dam/cfm/models/content-fragment-model");

FragmentTemplate tpl = templateOrModelRsc.adaptTo(FragmentTemplate.class);

try {

ContentFragment newFragment = tpl.createFragment(resolver.getResource(parent), "cwb-content-fragment-test",

"CWB POC Content Fragment Test.");

session.save();

}

The configuration and content fragment model is already present in crx. The code is throwing Null Pointer Exception.

Error:

Internal Server Error

Cannot serve request to /services/createContentFragment in com.capgroup.dam.core.CreateContentFragment

[Jörg_Hoh]

at which line is the NPE thrown? Can you indicate that in your pasted source code?

Thanks,

Jörg

[niteshsoni21]

NPE is coming on :

ContentFragment newFragment = tpl.createFragment(resolver.getResource(parent), "cwb-content-fragment-test",

"CWB POC Content Fragment Test.");

[Jörg_Hoh]

That means that "tpl" is null.

Which is perfectly possible if the adaptTo(FragmentTemplate.class) fails, returning NULL is a documented behavior of adaptTo(). This might be caused by the fact, that the resource is no ContentFragment.

[niteshsoni21]

Yes that's correct, the "tpl" is null and the questions which needs clarity are as below:

1)  Resource templateOrModelRsc = resolver.getResource("/conf/Test-Configuration/settings/dam/cfm/models/content-fragment-model");

Here the templateOrModelRsc  is resource for content fragment model and not the content fragment. Is this expecting the content fragment? The node properties for this resource is :

2) If it is expecting the content fragment in point 1, then the question is how to create the content fragment programatically? Because as per our requirement we have a use-case where we would be getting the content in the Json format from the service and using the content from Json, we would have to create the content fragment. For this we were following the approach mentioned here :" Customizing and Extending Content Fragments

3) Based on the details mentioned in the document our assumptions were :

a) Resource templateOrModelRsc  : This is the resource of the content fragment model that is present under the path : /conf/ (configuration - name) /settings/dam/cfm/models/

b) tpl.createFragment(parentRsc, "A fragment name", "A fragment description."); here the parent resource us the path of the folder where we need to create the content fragment, along with the name and description of the fragment that we need to give.

So our assumptions are not correct or does it need some correction? Would appreciate your help in this.

[Jörg_Hoh]

You can set the class "com.adobe.cq.dam.cfm.impl" to debug, which might print messages in case an adaption failed. Also you should make sure that your content fragment model has a "model" subnode (like  /conf/we-retail/settings/dam/cfm/models/we-retail-experience/ has).

Jörg

[niteshsoni21]

After setting the class "com.adobe.cq.dam.cfm.impl" to debug, there is no message getting printed. (I hope that is what you meant as mentioned in below screenshot)

Also I have validate that our content fragment model has a "model" subnode available.

[Jörg_Hoh]

Can you compare your own content fragment to  /content/dam/we-retail/en/experiences/48-hours-of-wilderness/48-hours-of-wilderness? Do you have the property "contentfragment = true" set? Also from your screenshot I wonder about the the primaryType = cq:PageContent... From a nodetype point of view conntentfragments are assets. Also the cq:dialog node below the model node shouldn't be there.

So it looks to me that there is quite a bit wrong.

Let me clear the ambiguity based on your queries:

Query 1: Can you compare your own content fragment to  /content/dam/we-retail/en/experiences/48-hours-of-wilderness/48-hours-of-wilderness? Do you have the property "contentfragment = true" set?

Answer : As mentioned above the requirement is to create the content fragment programatically and the content fragment does not exist at present. In the above details also I have mentioned that we are trying to create this content fragment programatically.

Query 2 : Also from your screenshot I wonder about the the primaryType = cq:PageContent... From a nodetype point of view conntentfragments are assets. Also the cq:dialog node below the model node shouldn't be there.

Answer : The screenshot that I share above was the screenshot of content fragment model nodes that are present at the location  (/conf/{project configuration}/settings/dam/cfm/models/{content-fragment-model}/jcr:content/model) as you asked in

your previous comment : Also you should make sure that your content fragment model has a "model" subnode (like  /conf/we-retail/settings/dam/cfm/models/we-retail-experience/ has).

The content fragment model nodes and properties matches to that of we-retail as below:

Hi Nitesh,

Please try below code snippet :

try{

          String name = request.getParameter("name");

          String title = request.getParameter("title");

          ResourceResolver resourceResolver = request.getResourceResolver();

          Resource parent = resourceResolver.getResource("/content/dam/we-retail");

          Resource template = resourceResolver.getResource("/libs/settings/dam/cfm/templates/simple/jcr:content");

          FragmentTemplate fragmentTemplate = template.adaptTo(FragmentTemplate.class);

          ContentFragment cf = CreateFragment(

                    parent,

                    template,

                    name,

                    title

            );

          resourceResolver.commit();

} catch(Exception e)

      {

          e.printStackTrace();

}

protected ContentFragment CreateFragment(Resource parent, Resource template, String name, String title) throws ContentFragmentException {

        Resource fragmentResource = parent.getChild(name);

        if (fragmentResource == null) {

            try {

                FragmentTemplate fragmentTemplate = template.adaptTo(FragmentTemplate.class);

                return (ContentFragment) MethodUtils.invokeMethod(fragmentTemplate, "createFragment", parent, name, title);

            } catch (Exception ex) {

    ex.printStackTrace();

                            return null;

            }

        } else {

            return fragmentResource.adaptTo(ContentFragment.class);

        }

    }
