We are migrating a customer project to the Cloud and for customer's needs we are using the LDAPIdentityProvider in publish to synchronize certain data from users.We are currently facing an intermittent exception during TLS Handshake. This error sometimes happens and stays for a while, then suddenly disappears and the calls work without issues.This issue only happens in AEMaaCS, when accessing from local or on-premise systems it works fine.Exception during authentication: Error while connecting to the ldap server.

 Hi all,I’m trying to convert a PDF stored in AEM DAM to a JSON tree structure (pages → paragraphs → lines) using Apache Tika’s PDFParser. Below is the servlet code I’m using: However, when I try to parse certain PDFs, I’m getting the following exception:org.apache.pdfbox.pdmodel.encryption.InvalidPasswordExceptionIt seems like the PDF might be password-protected, but I don’t have the password and some PDFs are not encrypted.package com.core.servlets; import com.day.cq.dam.api.Asset; import com.day.cq.dam.api.Rendition; import org.apache.sling.api.SlingHttpServletRequest; import org.apache.sling.api.SlingHttpServletResponse; import org.apache.sling.api.servlets.HttpConstants; import org.apache.sling.api.servlets.SlingAllMethodsServlet; import org.json.JSONArray; import org.json.JSONObject; import org.osgi.service.component.annotations.Component; import org.apache.tika.parser.pdf.PDFParser; import org.apache.tika.parser.ParseContext; import org.apache.tika.metadata.Metadata;

Hi All, I need to check readiness of my AEM applications/code to upgrade to AEM 6.5 LTS by running AEM 6.5 LTS Analyzer.I have gone through this page https://experienceleague.adobe.com/en/docs/experience-manager-65-lts/content/implementing/deploying/upgrading/aem-analyzer and understand that analyzer tool would generate a report which prepares issues from different categoriesApplication functionality that must be refactoredRepository items that must be moved to a supported locationConfiguration issuesAEM 6.5 features that have been removed by new functionality or that are currently not supported on AEM 6.5 LTSRemove Java and Guava API usagelater, there is another section talking about 'Content Transformer', what i understood from this is, it removes/delete typically JCR nodes by packaging under '/etc/packages/modernizer-content-transformation' as a backup, but the goal (checking readiness) is not fulfilled yet, I wonder what will be the next steps?Need to go through

Hi Everyone,I have a requirement to move our customized Adobe components into a proxy folder and update all content that currently references these components so they point to the new proxy versions.Example:Current component: buttonNew proxy component: buttonglThis means I need to update all pages to use the proxy component by modifying the sling:resourceType for every instance of the old button.Adobe Support recommended importing the content into code, applying the updates there, and then deploying through Cloud Manager (since we’re on AEM Cloud).I tried this approach in a demo project, but so far I don’t see my changes reflected in the AEM instance — currently testing on localhost. Steps I followed:Created a demo project, authored a new content page, and synced back to source code for making changes  2: Filter.xml  3: build using command: mvn clean install -PautoInstallSinglePackage4: Verify the changes are reflected in crxdeContent.xml<?xml version="1.0"

I'm working with AEM 6.5 and looking to optimize performance by configuring the minRecordLength property under org.apache.jackrabbit.oak.plugins.blob.datastore.FileDataStore.The documentation recommends setting this to 100 to ensure binaries (like DITA files) are saved in the Data Store instead of the Segment Store for better performance.However, I have a few questions:How can I verify where the binaries are currently being stored — Segment Store or Data Store — especially for different file types and sizes?If I don’t see the minRecordLength in the Felix Console (/system/console/configMgr), how do I confirm what value is being used by default?After setting minRecordLength=100, is there a reliable way (via logs or tools) to confirm that new uploads are being saved in Data Store?What metrics or logs should I track to evaluate performance improvements (e.g., segment size growth, compaction, GC)?I’ve uploaded files like small.txt and used scripts: def assetPath = "/content/dam/test-up

How to prevent the CSRF token call on non-SSO pages? 

I want to use GraphQL Query to get list of pages where XYZ Component is enabled based on set of input parameters. I have read multiple pieces of documentation on GraphQL Queries, and I learned that GraphQL is built to work with Content Fragments. Can anyone suggest way to achieve this requirement? 

Hi Team, Initially, the code worked as expected without using the embed property, while running on AMS AEM 6.5 (exact service pack version unknown). We are using the org.apache.sling.servlet-helpers dependency, which is correctly declared in the pom.xml. However, we suddenly encountered an issue with the target sync functionality. Upon debugging, we discovered that the servlet-helpers JAR was missing. The JAR is not visible in the AEM console or listed among the active bundles. To resolve this, we applied the embed property to include the JAR under the /apps folder. Unfortunately, this workaround has led to Sonar issues related to the dependency. We are currently using AEM version 6.5.21. The servlet-helpers JAR is available in AEM as a Cloud Service, but it appears to be missing in AEM 6.5. We're unsure whether it was replaced or bundled within another JAR. Is it acceptable to manually install the JAR via the AEM console under bundles, or is there a recommended way to restore it? Addi

might be best explain with an example: I have a servlet that returns true or false if HTTP post is successful.I also have a javax filter that checks if a user still has a session. if no session, redirect the user to the login page.User has 2 browser tabs open and both of them are displaying a form (could be the same or different forms).in tab1, user logs out.in tab2, user decides to submit the form (which is calling an servlet).In my filter and when processing the request for tab2, I w ant to redirect the user to the login page since they already logged out in tab1.How can I do this? I have tried response.sendRedirect and request.getRequestDispatcher. Both of them does not redirect the user to another page. Thanks

How to Automate AEM Offline Revision Cleanupby @giuseppebaglio  Dear AEM Community, I'd like to share my recently published article exploring how to transform the critical but tedious process of AEM Offline Revision Cleanup into an automated, one-command operation. IntroductionAEM's Oak repository eventually suffers from performance issues as unused data accumulates. My article presents a Bash script that transforms the tedious manual cleanup process into a single-command operation with built-in safety checks. This automation approach not only saves time but also reduces human error risk during critical maintenance operations. Key Points-  A powerful Bash script that automates AEM Offline Revision Cleanup with built-in safety checks.-  More than just a wrapper for oak-run.jar—it includes pre-flight checks, path validation, interactive prompts, and atomic operations.-  Features robust argument parsing, a streamlined Oak command engine, and safegua

Hi Community, I’m facing an issue with Experience Fragments in Cloud.We are trying to use the same XF across multiple sites. The fragment references are resolving fine on Author, but after publishing, some of the pages show broken references (the XF doesn’t render at all).The XF is published and available in Publish, The content path looks correct, Replication logs don’t show errors.Interestingly, if I republish the XF again, it sometimes works — but not consistently.Has anyone run into this problem where Experience Fragments intermittently fail to render on Publish? Any tips on what could be causing this or what I should check (replication agents, permissions, etc.)? Thanks for your help!

Hello Community,We have encountered an issue with the AEM Target integration, specifically related to saving and syncing activities in Target. We are receiving an error that does not seem valid in our case, as we have already referenced the audience with the offers/experience. Additionally, the same API integration works in other environments.We have also verified the permissions for the target group/service account for the relevant paths. Even after restarting the Test and Target bundle, the issue persists. Can someone advise what might be causing this issue and what fix is required to address it? Our AEM version is 6.5 SP22. We are using the out-of-the-box experience fragment component. We also tried using other components, but still had no luck. Verified the following areas:API integration has approver and editor privileges.Cloud service connectivity is in place.Cloud service configuration is updated in the root page.Able to pull audiences from Target.Test and Target replicatio

We need to support a new language - Montenegrin with the code as - cnr-ME.Can AEM even support it? By checking some of the existing language codes, what I see that aem can support 2 letters like "fr" or 5 letters like "fr-FR" but not 6 letters. I tried adding the language code under - /apps/wcm/core/resources/languages/.content.xml but it is still not getting resolved and we get the null value.Any insight will be helpful.Locale locale = LanguageUtil.getLocale("cnr-ME");System.out.println(locale); // prints null instead of cnr_ME<cnr jcr:primaryType="nt:unstructured" country="*" defaultCountry="cnr_me" language="Montenegro"/><cnr_me jcr:primaryType="nt:unstructured" country="Montenegro" language="Montenegrin"/>

Hi All,  I am trying to use CSV Assets Importer for our UAT environment, and I am getting an error message, and my assets are not being imported.I am using a NAS server that is connected to our UAT environment, where people go inside the folder create their own folders and drop their files inside. I have to get those files and then export them into AEM.   

Hello, I'm doing investigation regarding the state of the bundles.  When we performed rolling restart in publishers. We noticed 1 bundle were not proceeded to starting state. But this only happen in rare cases as we are doing a rolling restart multiple times and that bundle was properly start automatically by the AEM with no problem. Checking the Bundle Event written in error.log. I noticed the pattern that all bundle after stopped it will go to resolved state and start again. This is the expected case.Example 1:Example 2:  However, one bundle was not activated. Specifically, cq-dam-cfm-graphql was stopped and tagged with [FelixStartLevel]. After that, it transitioned to the Resolved state, but this time the tag changed to [OsgiInstallerImpl] instead of [FelixStartLevel]. Please disregard the last two lines in the log, as I manually triggered the bundle to start.  Here are the questions that got me stuck for a while:1. Is there any known issue or limi

Hi Everyone Hope all are staying safe and healthy!Has anyone taken the AD0-E117 Architect certification recently. Please let me know. Thanks 

Fellow AEM folks, The pressure to go "Headless" or "Hybrid" is real. Every client and every project seems to be asking for it. But is it always the right answer? The Good: For those who have made the leap, what was the biggest actual benefit you achieved? (e.g., developer freedom, faster site speed) The Bad: What was the most unexpected downside or complexity you faced? (e.g., content preview, author experience, cost) The Verdict: Is Headless AEM a must-have for future-proofing, or is it an overkill solution for most common use cases? When should a traditional AEM setup still be the preferred choice? Let's get past the jargon and talk about what really works (and what doesn't).

Everyone talks about Core Components, Cloud Service, and AI… but what about the hidden gems? Is there a little-known feature you use daily that saves tons of time? A workflow hack? A deployment trick? A authoring shortcut? Something that made you say, “Why didn’t I know about this earlier?!” Share your secret weapons!

Hello,   We often hear about the push to AEM Cloud for its new features and scalability. But what are some real-world situations where sticking with AEM Managed Services (AMS) actually makes more sense? Beyond just 'confidential data,' what are the practical, day-to-day reasons why an organization might choose AMS over Cloud?   I'm curious about those less-obvious advantages.     Since, Cloud or EDS is not best-fit-for-all, shouldn't Adobe plan innovations on AMS too? Any insights if something is already in roadmap?

Hi All,   I am trying to disable cache for HTML responses. I have these rules already in dispatcher config,   <LocationMatch "^/content/.*\.html$">Header always unset Cache-ControlHeader always unset ExpiresHeader always set Cache-Control "no-store, no-cache, max-age=0, must-revalidate"Header always set Pragma "no-cache"Header always set Surrogate-Control "no-store"</LocationMatch>   However, when I check response headers I still see this: cache-control: no-store, no-cache, max-age=0, must-revalidate,max-age=300   It looks like max-age=300 is being appended somewhere. I want to know from where this default Cache-Control: max-age=300 is getting added? What is the recommended way to override / remove this so my own no-cache rules are effective?   Thanks in advance !

We have a requirement of building functionality to show paginated list of users by the given filter criteria. Some of the filter criteria we have already achived by directly querying users from /home/users. We are facing difficulty in two filter criteria1) Find user by group name2) Find user by directory read access. We are unable to create query or anything that can support this requirement and returns paginated list of users. Following is our code so far. StringBuilder queryBuilder = new StringBuilder("SELECT * FROM [rep:User] AS u WHERE ISDESCENDANTNODE(u, [/home/users])"); if (StringUtils.isNotBlank(criteria.getUserId())) { queryBuilder.append(" AND (u.[rep:principalName] LIKE \"%").append(criteria.getUserId().trim()).append("%\")"); } if (StringUtils.isNotBlank(criteria.getUserMail())) { queryBuilder.append(" AND (u.[profile/email] LIKE \"%").append(criteria.getUserMail().trim()).append("%\")"); } if (StringUtils.isNotBlank(criteria.getCompanyName())) {
