    PasteControl

    This is a pure JAVA API to handle paste image and upload it

    Accessing clipboard is nothing very new in HTML 5. Gone are the days to print the screen of your computer, save it and upload it t server via File Up-loader. We , instead, experience the richness of the web by simply pasting our content on the web page itself. A very good example of the same may be experienced when you paste a screen shot on Github web itself . This project encourages developers to have such facility in the simple Java web application they develop. It's assumed that these developers are not using JSF Vaadin or ZK- any RIA framework already providing a component for uploading your clipboard content . This API is for those who use vanilla Servlet /JSP with some client side framework like Angular JS and Bootstrap , for example. The target beneficiary of this project are those who restrict server side to Vanilla Servlet /JSP and might come across such need often.For them, this API is good with regard to simplicity and over-head. Plus, YOU NEED NOT CODE at all.
