AEM 6.4 Connect java file with HTML File

I've been reading quiet a few but still am not able to get it done.

Current Java code:

html code

Folder Structure:

I'm trying to read metadata (specifically) size of image in java and load it back to html.

- I get my image via ${properties.fileReference}

- I prefer Local, but By bundle is alright as long as explained.

------------------------------ WORKFLOW: ---------------------------------

- Add image via

- get file via ${properties.fileReference}

- process in Java (local) (both sounds good too)

- return width and height to .html. (ex. <div> ${javaClass.width} - ${javaClass.height} </div>

See this document - we cover Granite Resource types and cover concepts like HTL/Sling Models:

I recommend that you go through the whole document too as it explains a lot of AEM Component concepts.

Also - I recommend placing your Java into a bundle - not a file in CRXDE lite.

to me this only works if the java-class is part of a bundle

Did you use data-sly-use.<object_name>="com.adobe.cq.wcm.core.components.models.<SlingModelClass>" ?

check any core component and validate your code against it.
