  1. Hi Hashim,

    We have a requirement where the links on blueprint needs to be updated for proper locale link in live copy.

    We created the DAM assets structure similar to site structure and placed similar PDF for “en” and “es” locale. Currently only two locales (English and Spanish).

    {/content/dam/testdemo/en and /content/dam/testdemo/es}

    I created a page with text “Click here” and added hyperlink for PDF from en folder. When live copy is created, the link still points to PDF from en folder.

    Page hierarchy (Blueprint): /content/testdemo/en/toolbar/testlink

    Live copy: /content/testdemo/es/testlink

    Requirement is that in live copy (in es folder) link should automatically update to point to similar PDF from es folder.

    Is this OOTB? then please help the configuration required. I used “Standard rollout config” while creating the live copy.

    If customization is needed, please guide with approach. Any links for examples with be appreciated.

    Thanks.

    • Hi, I couldn’t see what code you are using. But you can debug this easily – do check how the property is getting saved in multi-field . It should be different from textfield. You have to write code which can read from that multi-field property.

  4. Hi Hashim,
    I’m working in a version upgrade project from CQ5.5 to AEM 6.2. The issue is with the services, after installing the same code package in couple of author instances. One of them is working fine and in another instances some of the services were missed, this has been observed when I expand the bundle->used services block. Unable to figure out why the services were missed, this is our custom service not OOTB.
    Thanks,
    Ayyappa

    • Hi, Is there any error message while installing the web services ? Are you able to reproduce the issue in your local instance ? From 5.5 to 6.2 there were lots of methods which were deprecated and there could be some dependency mismatch. Closely observe the logs for Errors and Warnings.

  6. Hi Hashim,

    I am using AEM 5.6.1 service pack 2. Please suggest which Java version should I use? Is there some Performance slowness on Java 7 for AEM 5.6.1 SP2 or should I upgrade my java?

    • Hi, For AEM 561 , Java 1.7 is recommended. Performance slowness could be due to lots of reasons. Upgrading your java might not solve the issue. Its more related to Maintenance and Health of the environment.

  9. What causes the querybuilder to not return results on a publish instance?
    Currently I have a query built to pull assets out of the dam by a specific location and by a set of tags. The query works on my authoring instance but does not work on my publish. I’ve validated that the assets and the tags are published. As well as well anonymous access is allowed. What else is missing?

    • Hi Carolyn,
      Can you try to fire the query in Publish instance using /libs/cq/search/content/querydebug.html ?
      Check the logs, what is missing on publish instance. Check if all the data is same in author and publish instance. If you are using dispatcher check if proper filters are present there.

        Yes I have been using the query debugger to make sure that my query is correct and there isn’t anything wrong with the parameters I am using. I am able to get results on author for the parameters I am using in the debugger.

        After looking into the logs it was giving an error about not being able to delete an old tar file from “C:\aem\author\crx-quickstart\repository\segmentstore\”.
        Error from log:
        “org.apache.jackrabbit.oak.plugins.segment.file.FileStore TarMK GC: Failed to remove old file C:\aem\author\crx-quickstart\repository\segmentstore\data00057v.tar. Will retry later.”

        I’ve renamed the file to tarOLD but now the error has moved to “C:\aem\author\crx-quickstart\repository\segmentstore\data00057w.tar” . However, if I rename “data00057w.tar” to tarOLD I get a 500 error on the authoring instance. Both “data00057w.tar” and “data00057v.tar” are very old, dated 3/10/2017, since then I have the latest of 4/11/2017 “data00087a.tar”.

        Why is it trying to use such old tar files and how can I make author and the publish instance point to the latest of 4/11/2017 “data00087a.tar”?

  11. Hi,

    If I configure from OSGi bundle configuration console , configuration files is stored under “/apps/system/config”.
    1) Does the configuration under config folder is applied for both author and publish instance

    2) If yes then how will they we connected?
    If no? Do I need to package and install in publish.
    3)If I have configuration under config.publish of author instance, Does this configuration available on publish?

    • Hi Raghave,
      Its always advisable to create configurations based on environment runmodes. So you should create configurations like config.author and config.publish which are respectively applied on author and publishers.

      If a particular configuration isn’t present in both the above folders, it checks the config folder. The most matched runmode is selected. eg. if the same config is present in config, config.author and config.author.dev and your environment has runmodes like author,dev , the Configurations under config.author.dev is picked.

      I hope it clears your understanding.

    • Hi,
      Yes you can use Query Builder Search in the payload node under /etc/workflow/instances/server0/2017-04-19/test_workflow/data/payload . There should be the path of your page.

      No such information is stored at the Page level, but the payload information is stored in the Workflow Instances.

    • Hi,
      Yes sure. There could be 2 ways to do this –
      1. Your component (JS or Controller) makes an ajax call to Servlet from the page, Servlet calls the Services which in-turn makes third party API call , process the data (Query / Ordering) as per need and return a JSON back to page to display.
      2. Your component (JS or Controller) makes an ajax call directly to the third party API , and display on the page. Assuming the third party API is responsible for data processing as per need.

    • You have to write your Custom Authentication Handler and gave its priority above the AEM authentication handler. So whenever you will login , that Custom Authentication Handler will be called , from there you can make a call to your rest WS.

  21. Hello Hasim,
    We have migrated our application from 5.5 to 6.2 recently. Could you please help us in finding solutions for the following:
    1. Our application is mainly based on content(each page have atleast 6 sublevel content and whole content size would be aroung 20-30 gb)
    2. Search functionality is used in our app using EXTJS CQ.search.Util.getQueryBuilder().submit() (post extjs.form to bin/querybuilder.json) and using lens for displaying results.
    3. Search was slow in 5.5 but it became worse in 6.2
    4. Is there a way include SQL2 queries with less code changes(as our application is very huge and difficult to rewrite whole app)

    Could you please suggest to improve search either with existing EXTJS or changing to SQL2

    Thanks in Advance

  24. Hi Hashim, Is it possible to add multiple patterns of etc/map configurations with different sling matching patterns for the same domain? There is a requirement to add multiple url matching patterns to construct a redirection url, based on url matching patterns.

    • Hi Sudhakar,
      Yes you can do so. In fact all the redirects could be replaced by etc mappings using Regex redirection rules. eg :
      http://www.xyz.com
      {
      “jcr:primaryType”: “sling:Mapping”,

      “_SalesLeadCapture_any”: {
      “jcr:primaryType”: “sling:Mapping”,
      “sling:match”: “(?i)SalesLeadCapture/Pages/(.+).aspx$”,
      “sling:internalRedirect”: “/content/xyz/site/us/en/want-to-serve”
      },

      “_xyzfreestyle_any”: {
      “jcr:primaryType”: “sling:Mapping”,
      “sling:match”: “(?i)xyzfree/Pages/(.+).aspx$”,
      “sling:internalRedirect”: “/content/xyz/site/us/en/xyz-free”

    • Hi Prabodh,

      For any OOTB issue you can raise a daycare ticket. What is the error which you are getting in Console/ Logs ? Its difficult to debug without any logs or errors.

      Most probably if this is an OOTB issue you should use Vanilla instance and then upgrade to the latest Service pack for that instance with all the Hotfixes and then even if it doesn’t work raise a ticket to daycare.

  27. Hi @hashim,

    Recently we are trying to use vanity URLs in our CQ 5.6.1 with Service Pack 2.

    Vaniity URLS are working fine in publisher how ever when we are trying in dispatcher and live getting 404 Errors.

    We have followed below blog and configured every thing but still it is not working and getting 404 error.

    https://blog.kristianwright.com/2016/02/11/aem-dispatcher-and-vanity-urls/

    If I add allow rule for vanity url like { /type “allow” /glob “GET /vanitycheck.html” } then Dispatcher is looking for vanitycheck.html file inside document root path. For example if document root is content/en_us/ it is checking the url inside this path and in publisher it will be 404(ip:4503/content/en_us/vanitycheck.html).

    If I remove the allow rule then in dispatcher log it is saying filter rejected the URL.

    Are we missing any thing more from the above blog. Please help.

    Thanks,
    Aparna

  28. This is regarding connectivity of Marketing Cloud with the Mobile Application.
    We have AEM as backend and the Front end is handled by another team. We introduced Marketing Cloud to hold the assets. Cloud and AEM DAM Assets have been synchronized.
    Now, We need to connect the third party(IOS Mobile App) with the Marketing Cloud to access the assets there.
    Whenever attempted from front end, it preempts for a login since the asset URL requires Authentication. We do not have any connectivity between the Marketing Cloud and the App yet for the authentication.
    We need to make sure that whenever the Mobile Application hits a Cloud asset URL, it should not pre-empt for login.
