How to render velocity template in servlet?

[Chong Jing Hong]

I have a servlet class that handles csv file uploads. I want the plugin to render a velocity template after the upload is complete to say that the file upload has been completed. Here is my code so far:

public class BulkUserCreatorToolServlet extends HttpServlet{
private final TemplateRenderer renderer;    
private final WebResourceManager webResourceManager;
public BulkUserCreatorToolServlet(TemplateRenderer renderer, WebResourceManager webResourceManager){        
this.renderer = renderer;        
this.webResourceManager = webResourceManager;    
}
    @Override    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
        // Create a factory for disk-based file items        
DiskFileItemFactory factory = new DiskFileItemFactory();
        // Configure a repository (to ensure a secure temp location is used)        
ServletContext servletContext = this.getServletConfig().getServletContext();        
File repository = (File) servletContext.getAttribute("javax.servlet.context.tempdir");        
factory.setRepository(repository);
        // Create a new file upload handler        
ServletFileUpload upload = new ServletFileUpload(factory);
        try{            
//Parse the request to get file items            
List<FileItem> fileItems = upload.parseRequest(request);
            // Process the uploaded items            
Iterator<FileItem> iter = fileItems.iterator();         
while(iter.hasNext()){                
//handle file            
}            

Map<String, Object> context = new HashMap<String, Object>();            
context.put("testname", "testvalue");                        
response.setContentType("text/html;charset=UTF-8");            
response.getWriter().print(renderer.render("plugin-key","response-page.vm", context));        
}        
catch(FileUploadException e){            
e.printStackTrace();        
}        
catch(Exception e){            
e.printStackTrace();        
}    
}
}

 Upon upload, Page Not Found always shows. What did I do wrong? Thank you

have you defined the servlet in the atlassian-plugin.xml?
