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:

Building Experience Manager Components using Granite/Coral Resource Types

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.

Not sure but try these -

Option#1:   aem-touch-ui-validation/pathbrowser.html at master · nateyolles/aem-touch-ui-validation · GitHub

&lt;pathbrowserD
  jcr:primaryType="nt:unstructured"
  sling:resourceType="granite/ui/components/foundation/form/pathbrowser"
  fieldLabel="Required and allow non existing path"
  fieldDescription="Try entering an external URL"
  rootPath="/content/aem-touch-ui-validation"
  required="{Boolean}true"
  allowNonRootPath="{Boolean}true"
  allowNonExistingPath="{Boolean}true"
  name="./pathbrowserD"/&gt;

If this doesn't suffice, then write custom code to forcefully delete the chosen path that doesn't belong to the restricted folder and display message to let user know pick the specific path only:

Option#2:

Ok thanks!

Here another, how do you restrict the path item?

So that user is restricted to a certain folder only.

Thanks!

Granite types with coral in them are latest ones. Always use the latest ones on 6.4.

Update, I got to work. after I installed the complete package then doing the steps again. Maybe I was missing some coral component reference the first time.

@smacdonald2008

What's the difference between sling:resourceType that has Coral and the once that are without? btw, I've tested the link and found an error

Number 8 seems like a typo to me.

and followed the instructions carfully to number 34 yet it doesn't seem to reflect.

textfield and textarea doesn't reflect.

@gauravb10066713 I did use "data-sly-use.hero" and that's sufficient according to this link. HTL Java Use-API

Just tested the package that is available with the Sling Model section and it works perfectly.
