I created an option of get size in folder-browse and folder-details actiongroup. Whenever I click on Get Size option, I want the size of node to print on logger. I have created a class for finding the size of node using NodeService api. But, I am facinf problem in calling that java class from Alfresco UI. I have attached class file, share-custom-config.xml file and client side script of custom-doc-lib-action.js file.
