Hi @ronnie09 

 

1. JCR API
You may  adapt the resource to Node and use the JCR API to change property. However, it's a good idea to stick to one abstraction layer and in this case we somehow break the Resource abstraction provided by Sling.

Node node = resource.adaptTo(Node.class);
node.setProperty("property", "value");
node.getSession().save();


2. Read Value through ValueMap
You can also use ValueMap and ModifiableValueMap APIs to read and update property respectively.

ValueMap valueMap = resource.getValueMap();
valueMap.get("yourProperty", String.class);


Write/Modify property through ModifiableValueMap

ModifiableValueMap modifiableValueMap = resource.adaptTo(ModifiableValueMap.class);
modifiableValueMap.put("NewProperty", "Your Value");  //write
modifiableValueMap.put("OldProperty", "Updated Value"); // Modify

After writing property to a node, save these values by committing the 'resourceResolver'
You'll need system/service user for admin resourceResolver.

Santosh
