Hi @soniv 

 

Can you check if all the bundles are active in system console.

http://localhost:4502/system/console/bundles

 

Also which version of AEM you are using and what is the JDK version?

If it's AEM 6.5 with JDK 11 then please make the below lines of changes in sling.properties file under crx-quickstart/conf folder.

 

from sling.bootdelegation.sun=sun.*,com.sun.*

to sling.bootdelegation.sun=sun.*,com.sun.*,jdk.internal.reflect,jdk.internal.reflect.*

 

Thanks!

Hi @soniv 

 

The WKND Project has been designed for AEM as a Cloud Service.

It is also backward compatible with AEM 6.4.8.0 and 6.5.5.0 by adding the classic profile when executing a build, i.e:

 

mvn clean install -PautoInstallSinglePackage -Pclassic

 

Please try the above command and ensure you are running minimum of AEM 6.4.8.0 version.

 

Thanks!

Hi @soniv 

Are you running AEM 6.4.8.0 or greater version?

Also please check if you have the AEM core components package installed on your instance. I just tried this and it works for me.

Hi @soniv 

 

You need to download the service pack 6.4.8.0 and install it on your machine.

As per WKND tutorial it has to be minimun of AEM 6.4.8.0. Please see the link below with Building for AEM 6.x.x section.

https://github.com/adobe/aem-guides-wknd

 

You can download the 6.4.8.0 version from Adobe Package Share i.e. by logging into https://experience.adobe.com/#/downloads/content/software-distribution/en/aem.html with your adobe experience cloud id.

 

Thanks!

@Asutosh_Jena_  This is old post but I am still stuck on this. Recently, I have received new .jar which is newer version of AEM (6.5.0).
After following the tutorial again to install the WKND site i still see the blank pages with previously mentioned errors in web console.
Can you help?

Also when I see OSGI bundles. Every bundles are active accept the one recently installed. which is

wknD Sites Project - Core(aem-guildes-wkdn.core)

which shows status as installed but when I try to activate it it does not do anything.

 

Thanks.

Hi @Asutosh_Jena_,

Do we have instruction on how to install the service pack 6.4.8 
I have uploaded and installed the package via package manager and restarted the instance but it still show the 6.4.0 version as well it still has the same error I've got previously.

Hi @soniv 

 

You need to login to Package Manager and add the downloaded AEM 6.4.8.0 package.

Select the uploaded package and click Install.

Monitor the error.log. It will take around 5-7 min to complete the installation process. Once the installation is complete navigate to http://localhost:4502/system/console/productinfo

 

It will show Installed Products (Adobe Experience Manager (6.4.8.0))
