Enabling basic authentication for specific website in dispatcher : Adobe CQ5/Adobe AEM

Enabling basic authentication for specific website in dispatcher : Adobe CQ5/Adobe AEM

Create a file dispatcher.htaccess in dispatcher.
Create the required users by using the following commands.

htpasswd -c /etc/httpd/conf/dispatcher.htaccess user1

Add the following configurations to the httpd.conf, change the site URL and AuthUserFile accordingly:

# unsets authorization header when sending request to AEM
RequestHeader unset Authorization
SetEnvIf Request_URI ^/content/en* auth=1
AuthName "Please login to access english part"
AuthType Basic
AuthUserFile /etc/httpd/conf/dispatcher.htaccess
# first, allow everybody
Order Allow,Deny
Satisfy any
Allow from all
Require valid-user
# then, deny only if required
Deny from env=auth

This will enable the the basic authentication for the website path starts with /content/en

If the site is enabled for https then add the following content to the ssl.conf file

<Location />
# unsets authorization header when sending request to AEM
RequestHeader unset Authorization
SetEnvIf Request_URI ^/content/en* auths=1
AuthName "Please login to access english part"
AuthType Basic
AuthUserFile /etc/httpd/conf/dispatcher.htaccess
# first, allow everybody
Order Allow,Deny
Satisfy any
Allow from all
Require valid-user
# then, deny only if required
Deny from env=auths

Adobe CQ/Adobe AEM: Configuration Services for Multiple Sites through configurationFactory

Adobe CQ/Adobe AEM: Configuration Services for Multiple Sites through configurationFactory

Sometimes, we have to define configuration services that will differ only with configuration values. For e.g we will have different sites that will use the same configuration service but with different configuration values specific to sites.

In this scenario, we have to create a site specific configuration service for all the sites (multiple services) but OSGI provides the concept of ServiceFactories, the service factory can be used to create configuration services with same set of properties and different values.

As an example let’s assume, we have two different sites that will use the same configuration service but require site specific configuration values. The configurationFactory can be used to create configuration service for different sites.

configurationFactory to create site specific cconfigurations and to retrieve the site specific configuration properties.

Invalidate dispatcher cache after successfull jenkins build - AEM/Adobe CQ5

Invalidate dispatcher cache after successful Jenkins build - AEM/Adobe CQ5

This post will explain how to invalidate the cache in Adobe Experience Manager after successful Jenkins build.

Login to Jenkins console

Open the job and click on configuration

Add post-build step of type  “Execute Shell” and select “Run only if build succeeds”

Enter the below script and click on  - Change the dispatcher host name accordingly.

/usr/bin/curl -H "CQ-Action: DELETE" -H "CQ-Handle:/" -H "Content-Length: 0" -H "Content-Type: application/octet-stream" --noproxy .com http://<<dispatcher host name>>/dispatcher/invalidate.cache

If multiple dispatcher are configured then configure the dispatchers as shown below in the script.

/usr/bin/curl -H "CQ-Action: DELETE" -H "CQ-Handle:/" -H "Content-Length: 0" -H "Content-Type: application/octet-stream" --noproxy .com http://{dispatcher1, dispatcher2, dispatcher3, dispatcher4}.com/dispatcher/invalidate.cache

Dispatcher caching issue while displaying the image renditions in Adobe Experience Manager(AEM)

We are using the image renditions to display the images for different devices in Adobe Experience Manager(AEM).

The HTML5 Adaptive image is used as shown below to display the images for different devices.

<img src="/content/dam/Albin/Untitled.jpg" srcset="/content/dam/Albin/Untitled.jpg/jcr:content/renditions/cq5dam.thumbnail.319.319.png 1x,/content/dam/Albin/Untitled.jpg" alt="Sample Image">

/content/dam/Albin/Untitled.jpg - Original image
/content/dam/Albin/Untitled.jpg/jcr:content/renditions/cq5dam.thumbnail.319.319.png - Rendition for 1x devices.

If the image is first accessed from the mobile devices then Untitled.jpg folder is created to cache the renditions image(rendition images will be matched for mobile devices) - /content/dam/Albin/Untitled.jpg/jcr:content/renditions/cq5dam.thumbnail.319.319.png

While the image is getting accessed from desktop browsers then dispatcher will try to return the folder Untitled.jpg as image(/content/dam/Albin/Untitled.jpg - original image will be matched for desktop browsers) so the image link will be broken in browser.

In other hand, if the image is first accessed from desktop browser then dispatcher caches Untitled.jpg as image. The subsequent request to the renditions image will not find the images in dispatcher cache so the image will be retrieved from publisher for rendering(rendition images will not be cached in this scenario as untitled.jpg is created as a image).

How to create different renditions for the Image in AEM/Adobe CQ5?

How to create different renditions for the Image in AEM/Adobe CQ5?

While uploading the images to DAM,Adobe Experience Manager(AEM) will create renditions of an image that include different sizes of the same image.This can be helpful when we need to create thumbnails or smaller views of large, high-resolution images.

We can configure the DAM Update Asset workflow to create the different renditions.

• Login to http://localhost:4502/etc/workflow/models/dam/update_asset.html
• In the workflow model select the thumbnail creation step and edit, in the process tab of the step we can add custom rendition values.
• Save the workflow

How to use HTML5 adaptive image in AEM/Adobe CQ5?

How to use HTML5 adaptive image in AEM/Adobe CQ5?

This post will explain how to use HTML5 adaptive image in Adobe Experience Manager(AEM)

The srcset attribute in HTML5 <img> element, allows us to specify different images for varying viewport widths and pixel densities. This allows us to load a larger image for new high resolution devices while displaying lower resolution images for others

<img src="image-src.png" srcset="image-1x.png 1x, image-2x.png 2x,image-3x.png 3x, image-4x.png 4x">

The width also can be specified to select the images.

<img src="small.jpg" srcset="medium.jpg 1000w, large.jpg 2000w" alt="Sample Image">

While uploading the images to DAM, Adobe CQ5 will create renditions of an image that include different sizes of the same image.This can be helpful when we need to create thumbnails or smaller views of large, high-resolution images.

The original or different rendition images can be used in HTML5 Adaptive image to display the images based on pixel density of the device,  browser will serve the image based on the resolution of the client.

<img src="/content/dam/Albin/Untitled.jpg/jcr:content/renditions/original" srcset="/content/dam/Albin/Untitled.jpg/jcr:content/renditions/cq5dam.thumbnail.319.319.png 1x,/content/dam/Albin/Untitled.jpg/jcr:content/renditions/original" alt="Sample Image">

NullPointerException: currentDesign.getDoctype(currentStyle).toRequest(request) - AEM/Adobe CQ5

NullPointerException:  currentDesign.getDoctype(currentStyle).toRequest(request) - AEM/Adobe CQ5

We were getting the NullpoiterException while accessing the pages in Adobe Experience Manager(AEM)

Caused by: java.lang.NullPointerException

NullpointerException is thrown while getting the Doctype of the page design.

if (currentDesign != null) {
        currentDesign.getDoctype(currentStyle).toRequest(request);
    }

This issue was getting resolved after restarting the server.

After analysis the currentDesign  and currentStyle objects are not null and getDoctype method is throwing NullpoiterException.

The currentStyle  refers to the path (currentStyle.getPath())- /etc/designs/default.

By default /etc/designs/default/jcr:content path will not have cq:doctype property specified.

To resolve the issue we have added the  cq:doctype - html_5 property to /etc/designs/default/jcr:content

If the property is already available then delete the same and add again.
