We can pass values from a servlet to HTML page or JSP using request.getParameter(String[]); If you are using Struts Framework then we need to do some changes in StrutsConfig.xml while after global actions and Action Mapping tags we need to properly match Bean values i.e. Getters and setters and depending upon the Request on client side we can enhance our code and produce desired result.
