java.lang.ClassCastException for the same class com.sample.test.Test cannot be cast to com.sample.test.Test - Adobe Experience Manager(AEM)

java.lang.ClassCastException for the same class com.sample.test.Test cannot be cast to com.sample.test.Test - Adobe Experience Manager(AEM)

We were facing a strange ClassCastException - ClassCastException pointing to the same class in Adobe Experience Manager(AEM)

java.lang.ClassCastException: com.sample.test.Test cannot be cast to com.sample.test.Test

While analyzing through depfinder - http://localhost:4502/system/console/depfinder, there is two version of the same class available from two different packages.

But this class is only defined in one of the package and referred in the other package, after analyzing the Sling class loading is little different - If one of the class com.sample.test.Test is referred from different package, Sling copies the classes locally to the target package and if the target package export the same package(<Export-Package>) -  com.sample.* then Sling export the classes copied from other package that matches the export pattern, in this case our target package is already exporting com.sample.* so two version of same class is available now. This will lead to the ClassCastException specified above.

To fix this issue, we can change the target package pom.xml file to restrict the export of referred classes from other package.

<Export-Package>com.sample.*,!com.sample.test</Export-Package>

Please make sure the restricted package - !com.sample.test is kept after the wider package - com.sample.*

Now only one version of the class from source package is available for reference.

Based on the analysis the Dynamic Tag Management(DTM) cloud connector is not using the the proxy server details configured to establish the connection.
This is the defect with the connector, raise a ticket with Adobe support team to  receive the fix.

As a temporary fix update DTMConfigurationUtil.java in bundle - /libs/cq/cloudservices/install/cq-dtm-0.1.8.jar to support proxy server while establishing the connectivity.

DTMConfigurationUtil.java - callDTMApi

 HttpHost proxy = new HttpHost("proxy.com",80);
 RequestConfig config = RequestConfig.custom().setProxy(proxy).build();   
 apiRequest.setConfig(config);

Refer the following post for updating the java class in a bundle - https://www.albinsblog.com/2017/04/updating-salesforce-connector-jarcq-mcm-salesforce-adobe-cq5-aem.html https://www.albinsblog.com/2017/04/updating-salesforce-connector-jarcq-mcm-salesforce-adobe-cq5-aem.html

In place upgrade of Adobe Experience Manager(AEM) to 6.2 version

In place upgrade of Adobe Experience Manager(AEM) to 6.2 version

This post will explain the steps to in place upgrade of Adobe Experience Manager(AEM) server to 6.2 version
  • Backup the current Adobe Experience Manager(AEM) instance
  • Copy aem-quickstart-6.2.0.jar next to current Adobe Experience Manager(AEM) crx-quickstart
  • Perform regular maintenance activities - including workflow purge
  • Run the Traversal check and Data store consistency check one by one - http://localhost:4502/system/console/repositorycheck
  • Disable custom login moduels if any - make sure the default login module is configured as below in crx-quickstart/repository/repository.xml
        <LoginModule class="com.day.crx.core.CRXLoginModule">
            <param name="anonymousId" value="anonymous"/>
            <param name="adminId" value="admin"/>
            <param name="disableNTLMAuth" value="true"/>
            <param name="tokenExpiration" value="43200000"/>
            <!-- param name="trust_credentials_attribute" value="d5b9167e95dad6e7d3b5d6fa8df48af8"/ -->
</LoginModule>
  • Stop the Adobe Experience Manager(AEM) server
  • Remove all log files under crx-quickstart/logs
  • chown -R aem:aem crx-quickstart(this command is required if AEM is running with different user)
  • su aem(this commad is required if AEM is running with diffrent user)
  • If you are migrating from AEM 5.x or AEM 6.0 with a CRX2 backend then follow URL - https://www.albinsblog.com/2015/09/upgrading-aemadobe-cq5-5.6.1-to-aemadobe-cq5-6.1.html
  • If you are migrating from AEM 6.0 with a oak backend or 6.1 then execute java -jar aem-quickstart-6.2.0.jar -r author,crx3,crx3tar
  • Monitor error.log and stderr.log – Once the migration is completed stderr.log will show the following message                                                                                                                           
          “Opening browser using cmd=x-www-browser "http://localhost:4502/"  || gnome-open                       "http://localhost:4502/"  || firefox "http://localhost:4502/"  || mozilla "http://localhost:4502/"               || konqueror "http://localhost:4502/"  || netscape "http://localhost:4502/"  || chromium-browser           "http://localhost:4502/"  || opera "http://localhost:4502/"  || links "http://localhost:4502/"  ||                lynx "http://localhost:4502/"
           Startup time:442 seconds
           http://localhost:4502/
           Quickstart started”

URL to check the version - http://localhost:4502/system/console/productinfo

Check the bundles in Installed state, most of the obsolete bundles will be removed after upgrade but some cases some of  the obsolete bundles will not be uninstalled - This can be ignored or uninstalled manually (better to compare the bundles with fresh 6.2 installation).Refer the following URL for details on obsolete bundles https://docs.adobe.com/docs/en/aem/6-2/deploy/upgrade/obsolete-bundles.html

Custom core bundles may not start due to the dependency issues. Refer the following URL for API difference between 6.1 and 6.2 - https://docs.adobe.com/docs/en/aem/6-2/develop/ref/diff-previous/changes/changes-summary.html

Update the maven dependency with correct version by identifying the version through depfinder -
http://localhost:4502/system/console/depfinder

Updating the Salesforce Connector jar(cq-mcm-salesforce) to support Proxy server and TLS 1.1 - Adobe CQ5/AEM

Updating the Salesforce Connector jar(cq-mcm-salesforce) to support Proxy server and TLS 1.1 - Adobe CQ5/AEM


Updating the Salesforce Connector jar(cq-mcm-salesforce) to support Proxy server and TLS 1.1 - Adobe CQ5/Adobe Experience Manager(AEM)

Steps to update Salesforce Connector jar(cq-mcm-salesforce) to support Proxy server and TLS 1.1

The AEM Salesforce connector is not supporting the Proxy Server and TLS 1.1 or TLS 1.2 versions:

This is the defect with AEM Salesforce Connector, the connector will not be able to connect to Salesforce server behind the proxy server. The SalesforceClient.java class in the connector should be changed to enable the proxy server.

The connector will not be able to connect to Salesforce server if the Adobe Experience Manager(AEM) server is ruuning with Jave version less than 1.8, Java versions less than 1.8 will not support TLS 1.1 or higher version by default but Salesforce expect TLS 1.1 or TLS 1.2 to establish the connectivity. The SalesforceClient.java class in the connector should be changed to support the TLS 1.1 or TLS 1.2, if the  AEM server is running with Java version less than 1.8

I have tested this in Adobe Experience Manager(AEM) 6.1 version, this should be the same case with 6.2 also. Raise an issue with Adobe to get the hotfix until the issue is permanently fixed.

The below is the quick fix to resolve the issue.

Download the /libs/mcm/salesforce/install/cq-mcm-salesforce-1.2.8.jar through package manager

Create a sample project -  mvn org.apache.maven.plugins:maven-archetype-plugin:2.4:generate -DarchetypeGroupId=com.adobe.granite.archetypes -DarchetypeArtifactId=aem-project-archetype  -DarchetypeVersion=10 -DarchetypeCatalog=https://repo.adobe.com/nexus/content/groups/public/

              groupId=com.day.cq.mcm
              artifactId=cq-mcm-salesforce
              version=1.2.8
              package=com.adobe.cq.mcm.salesforce 
             Enter mcm for other values
 
Execute mvn eclipse:eclipse command in the parent folder of the project and load the project to eclipse

Extract the downloaded jar file and decompile the class files using JAD
Create all the java classes manually in core project with same package details and copy the content from decompiled classes
Replace the pom.xml of core project with the pom.xml content from the decompiled jar

How to customize the page properties Dialog to include dynamic DropDownList in AEM/CQ5

How to customize the page properties Dialog to include dynamic DropDownList in AEM/CQ5

This post will explain the details to customize page properties Dialog in both Touch and Classic UI's, the version used for implementing this is Adobe Experience Manager(AEM) 6.1.

The basic page properties dialog will be displayed if the sling:resourceSuperType of the page rendering component is specified as foundation page component(wcm/foundation/components/page for Sightly and foundation/components/page for JSP)

Steps to customize the basic page properties and including dynamic DropDownList to the dialog.

/apps/training/components/page-content/ will be referred as the page rendering component path in the post.

Classic UI:

Copy /libs/foundation/components/page/dialog to /apps/training/components/page-content/
Rename the new node to required name e.g. custom

Copy /libs/foundation/components/page/tab_basic to /apps/training/components/page-content/
Rename /apps/training/components/page-content/tab_basic to required name e.g tab_custom

Remove all the nodes under  /apps/training/components/page-content/tab_custom/items

Change path value in the node /apps/training/components/page-content/dialog/items/tabs/items/custom to /apps/training/components/page-content/tab_custom.infinity.json

Change title property of the node /apps/training/components/page-content/tab_custom to required value e.g Custom

Save All configurations

Open the page from site Admin(e.g. http://localhost:4502/cf#/content/training-site/en.html), now the new tab(Custom) will be added to the page properties with empty panel

Configure the data in Configuration.txt file accordingly.
Email will be triggered whenever the configured Queue is disabled, blocked, paused or the pending request is more than the configured threshold.

Executable jar file can be generated for the java class and scheduled for continuous monitoring.

How to invalidate the dispatcher cache for dam assets referred from multiple sites? - Adobe CQ5/AEM

How to invalidate the dispatcher cache for dam assets referred from multiple sites? - Adobe CQ5/AEM

Sometimes, we may have the scenario like the same DAM asset is referred from multiple sites and cached locally(site specific) in Adobe Experience Manager(AEM) dispatcher for the different sites. The local cache of the different sites should be invalidated whenever the asset is modified.

This post will explain how to achieve the above mentioned scenario.

Create a user in all the publisher and provide only the access to DAM- /content/dam


Create a flush agent for individual sites with the following details in all the publishers(repeat the below step for all the sites)

How to populate the current page path to the dialog through EXT JS - Adobe Experience Manager(AEM) 6.1

This post will explain, how to populate the current page path to the dialog through EXT JS - Adobe Experience Manager(AEM ) 6.1

Add the listener for the widget and use the below script.

function(widget) {
        var currentPath;
if(CQ.wcm.SiteAdmin.hasListSelection()) {
        var grid = CQ.wcm.SiteAdmin.getActiveGrid();
        var selections = grid.getSelectionModel().getSelections();
currentPath = selections[0].id;
console.log(currentPath);
widget.setValue(currentPath)
}
}

Caused by: org.apache.sling.api.resource.PersistenceException: Resource is not modifiable - Adobe CQ5/AEM

 Caused by: org.apache.sling.api.resource.PersistenceException: Resource is not modifiable - Adobe CQ5/AEM


The below exception will be thrown most of the cases while accessing the servlet with post from Adobe Experience Manager(AEM).

The actual issue is Adobe Experience Manager(AEM) could not ale to resolve the servlet and assumes it as a resource path but this is not a valid resource path, the below exception will be thrown when AEM tries to set the property values.

Caused by: org.apache.sling.api.resource.PersistenceException: Resource at '/services/formservlet' is not modifiable.
    at org.apache.sling.servlets.post.impl.helper.SlingPropertyValueHandler.setProperty(SlingPropertyValueHandler.java:153)
    at org.apache.sling.servlets.post.impl.operations.ModifyOperation.writeContent(ModifyOperation.java:411)
    at org.apache.sling.servlets.post.impl.operations.ModifyOperation.doRun(ModifyOperation.java:101)

The steps to narrow down the issue:

Resolve the Servlet:

Go to http://<<AEM Host>>:4503/system/console/configMgr - Sling--> Sling Servlet Resolver and resolve the servlet path, if the servlet path is resolved then there is no issue if not the servlet is not configured properly.
