AEM 6.5.19 Sling Model is not being registered

Hi,

 

I am using AEM 6.5.19 and created a simple sling servlet adapting to Resource. However when I use the sling model in html, getting the following error:

 

org.apache.sling.api.SlingException: Cannot get DefaultSlingScript: No use provider could resolve identifier com.kishore.project.core.models.kishoremodel
at org.apache.sling.scripting.core.impl.DefaultSlingScript.service(DefaultSlingScript.java:510) [org.apache.sling.scripting.core:2.3.2]
at org.apache.sling.engine.impl.request.RequestData.service(RequestData.java:579) [org.apache.sling.engine:2.7.10.B0006]
at org.apache.sling.engine.impl.filter.SlingComponentFilterChain.render(SlingComponentFilterChain.java:45) [org.apache.sling.engine:2.7.10.B0006]

 

When i check inn status-sling models, not finding my sling model.

 

Question: Do i need to include anything in the POM.xml to support sling models? Please note my project was generated using Maven archetype 39.

 

Any help is highly appriciated.

 

Regards,

Kishore

Hi @kishored6899358 ,

Sling model should be in TitleCase, change it to Kishoremodel in java and sightly both.

Thanks

Hi Kishore,

 

It could be one of the two reasons mentioned below: 

  • package-info.json may not be present in the package. In your case, this package - com.kishore.project.core.models 

  • Sling-Model-Packages may have incorrect package path. Check the bnd-maven-plugin configuration in pom.xml 

I came across this answer https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/what-s-the-advantage-of-using-package-info-json-vs-export/m-p/670398/highlight/true#M167641 in the community which has great details on different approaches of sling model exporters. 

 

Thanks,

Lokesh

    Hi @lokesh_vajrala 

    Thank you for your reply

     

    The package-info.json is available under models

    @Version("1.0")
    package com.kishore.project.core.models;

    import org.osgi.annotation.versioning.Version;


    And using ModelsScannerPlugin for sling model registration.

     

    Regards,

    Kishore

      Hi @kishored6899358 ,

      You may check typo in model call- 

      <sly data-sly-use.model="com.kishore.project.core.models.kishoremodel" /> 

      try K of Kishoremodel in camelcae as most probably your sling model would be in TitleCase

       

      Cross check if package-info.java file present

      Check the import statements

      Thanks

        Hi @mukeshyadav_ 

         

        The model is in lowercase only and the package-info.json is available under the models.

         

        Regards,

        Kishore
