Facing issue with java.lang.NoClassDefFoundError: org/apache/velocity/context/Context

Solution 1
You need to add the velocity-version.jar to your server classpath, you can put it in the lib folder of your tomcat server, or you can put this jar in the WEB-INF/lib folder of your project.
Solution 2
Download velocity-1.7 jar and add in to eclipse Deployment Assembly then restart the server.

I'm a new learner velocity. I am trying to display the template in HTML format by writing a servlet for that. The following is my servlet code
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { PrintWriter out = response.getWriter(); VelocityEngine velocityEngine = new VelocityEngine(); try { velocityEngine.init(); Template template = velocityEngine.getTemplate("./src/Menu.txt"); VelocityContext context = new VelocityContext(); context.put( "special-1", "./src/special-1.txt" ); context.put( "special-2", "./src/special-2.txt" ); context.put( "special-3", "./src/special-3.txt" ); StringWriter writer = new StringWriter(); template.merge(context, writer); out.println(writer); } catch (Exception e) { e.printStackTrace(); } }
And following is the stack trace im getting...
