Yes, this servlet simply returns unique ID. In JSON (or JSONP) format. You can use it in your Javascript application for getting unique ID from the server. How to use it: 1) download idPackage.jar and save it in WEB-INF/lib 2) describe ID servlet in web.xml file
<servlet> <servlet-name>IDServlet</servlet-name> <servlet-class>com.jsos.id.IDServlet</servlet-class> </servlet> 3) define a mapping:
<servlet-mapping> <servlet-name>IDServlet</servlet-name> <url-pattern>/servlet/ID</url-pattern> </servlet-mapping> and now you can use it. For JSON request call
http://your_host/servlet/ID, for JSONP use a parameter callback that
describes your Javascript function. In this example our callback function is myID:
function myID(v) { alert("New ID:"+v.id); } var cbscript = document.createElement("script"); cbscript.src = 'http://your_host/servlet/ID?callback=myID'; cbscript.type = 'text/javascript'; document.body.appendChild(cbscript); For downloading: servlet: idPackage.jar
