Is the Products web script installed and working correctly on your Alfresco repo? You can check by browsing to the Web Scripts Home i,e, http://localhost:8080/alfresco/service/, select “Browse by web script package”, scroll down and select “/products”. You can then click on the GET link i.e. GET / alfresco/service/products/get and this will run the web script. If it is working it will return a JSON response listing some example products. If it fails to return any products, check your AVM dir structure. It loads the products from the /content/products/source dir.
Other things to check: 1) is your repo running at http://localhost:8080 as I mentioned within the prerequisites? 2) Is the username/pass admin/admin? If not edit in the web-framework-config-custom.xml.
