I need a basic app created to allow users to login to their ebay account and authorize my app to post items to their ebay by generating user tokens. I want to utilize the ebay trading api and I have a developer account through ebay so I can provide the necessary keys or you can create the keys and I will change them to my own later on. I need this done in JAVA and JSP. This will be incorporated into an existing JAVA web app so all the ebay fields will be populated from that app, all I need is the basic structure done so I can incorporate it smoothly. I need the user to authorize my app to post to their ebay (one time setup), fill out a form, then I need a service class that will take the form variables and store them to the necessary fields for the ebay trading api and then take them to a jsp page that will show the user their selling fees and have a submit button to send to their ebay and redirect them to a predetermined link on my website.
