How to implement Servlet to find smart tags attached with an image?

[prachimathur]

Hi, 

I just want to know how to implement a servlet to find search the smart tags attached with an image.

Is there we have to make changes in a already present servlet or to create a new servlet?

Hi @prachimathur ,

Adapt the image path as asset and try to get the required properties from Asset metadata. You may cross check the property name from crxde node

Hi,

This way suggests the sling model code to get the metadata but is there any way we can get smart tags through servlet.

Hi @prachimathur 
Can you check the CRXDE, to see where the smart tags are stored for a image.

Then create a servlet which accept image path and you can serach for the smart tag for that assets,

basic code example

https://github.com/arunpatidar02/aem63app-repo/blob/master/java/DownloadAssetsImage.java 

Resource assetResource = resourceResolver.getResource(assetPath);
        if (assetResource != null) {
            // Get the Asset object from the resource
            Asset asset = assetResource.adaptTo(Asset.class);
            if (asset != null) {
                // Fetch the smart tags from the metadata node of the asset
                String[] tagIds = asset.getMetadataValue("predictedTags");
                
                // Get the TagManager from the resource resolver
                TagManager tagManager = resourceResolver.adaptTo(TagManager.class);
                
                // Convert tag IDs to Tag objects
                if (tagIds != null && tagManager != null) {
                    for (String tagId : tagIds) {
                        Tag tag = tagManager.resolve(tagId);
                        if (tag != null) {
                            tags.add(tag);
                        }
                    }
                }
            }
