Hi!

After creating the WKND tutorial project I am facing issues.

In http://localhost:4502/sites.html/content/wknd by selecting edit - page opens empty in the editor.

I am working with AEM 6.5

Apache Maven 3.6.3

Java version: 11.0.8

I would be really happy about every suggestion on how to fix this problem. 🙂Capture.PNGCapture2.PNGCapture3.PNG

Thank you!

Hi @hello-liana2 

Have you deployed WKND project?

 

if not please deploy code by cloning the project from here https://github.com/adobe/aem-guides-wknd

If yes, please check "WKND Sites Project - Core" bundle status whether its in active status or not. if its not active check if there is any dependency error.

 

Hope this helps!

Hi @hello-liana2 ,

 

  1. If you are using JDK 11 with AEM 6.5 instance, some of the pages might display as blank after deploying some packages. The following error message displays in the log file:
*ERROR* [OsgiInstallerImpl] org.apache.sling.scripting.sightly bundle org.apache.sling.scripting.sightly:1.1.2.1_4_0 (558)[org.apache.sling.scripting.sightly.impl.engine.extension.use.JavaUseProvider(3345)] : Error during instantiation of the implementation object (java.lang.NoClassDefFoundError: jdk/internal/reflect/ConstructorAccessorImpl)
java.lang.NoClassDefFoundError: jdk/internal/reflect/ConstructorAccessorImpl

To resolve this error:
  • Stop the AEM instance. Go to <aem_server_path_on_server>crx-quickstart\conf and open the sling.properties file. Adobe recommends taking a backup of this file.
  • Search for org.osgi.framework.bootdelegation= . Add jdk.internal.reflect,jdk.internal.reflect.* properties to display the result as.
org.osgi.framework.bootdelegation=sun.*,com.sun.*,jdk.internal.reflect,jdk.internal.reflect.*

  • Save the file and restart the AEM instance.

     2. When you create the page component you need to include the Resource super type                 as wcm/foundation/components/page which is pointing to Page component otherwise you will see balnk.

 

     3. Alternatively, you can setup wknd code using this helpx article :https://helpx.adobe.com/in/experience-manager/kt/sites/using/getting-started-wknd-tutorial-develop/p...

 

Hope this helps!

 

Regards,

Santosh
