Session title: Web Application Development with Spring, GWT and MVP

Session type: Case Study / Experience Report

Session duration: 90

Speaker: Paul Grenyer

Biography: Paul has been programming in one form or another for over 20 years. After several years using C++ and a brief period using C#, Paul is now happy somewhere he hoped he'd never be, programming in Java.

After time in industries such as marking machinery, direct mail, mobile phones, investment banking and Internet TV, Paul is currently working for a company based in Norwich where he heads up an ever growing team of senior and highly skilled people.

When he's not programming and family life allows, Paul thoroughly enjoys science fiction, heavy metal and cycling.

Session description: In Enterprise Web Application Development in Java with AJAX and ORMs (ACCU London March 2010 and ACCU2010) I spoke about how to develop and test a Data Access Layer and integrate it with a very simple Google Web Toolkit (GWT) based front end.

In Web Application Development with Spring, GWT and MVP I will demonstrate how to take advantage of Spring's Model View Controller implementation to add Spring Security to a GWT application and show how an adapter can be used to map it onto almost any user domain model. I will then go on to demonstrate the power of the Google Web Toolkit when developing web applications.

Traditionally web based applications, and even some that make use of AJAX, require large numbers of round trips to a server followed by the rendering of entire web pages each time something is submitted. Coupling GWT with the powerful and aesthetically pleasing GXT widget library (which is based on the EXT JS JavaScript library used by web applications such as Nexus) and the Model View Presenter pattern I will show how to create a powerful web application that runs almost entirely within a browser, with much of the same power as a desktop application, only calling to the server to send or retrieve the bare minimum of data.

Throughout the session I will build an application and demonstrate each new feature by running and operating the application.

No knowledge of the previous session is required.

Write Your Own Load Balancer: A worked Example

By
I was out walking with a techie friend of mine I’d not seen for a while and he asked me if I’d written anything recently. I hadn’t, other than an article on data sharing a few months before and I realised I was missing it. Well, not the writing itself, but the end result. In the last few weeks, another friend of mine, John Cricket , has been setting weekly code challenges via linkedin and his new website, https://codingchallenges.fyi/ . They were all quite interesting, but one in particular on writing load balancers appealed, so I thought I’d kill two birds with one stone and write up a worked example. You’ll find my worked example below. The challenge itself is italics and voice is that of John Crickets. The Coding Challenge https://codingchallenges.fyi/challenges/challenge-load-balancer/ Write Your Own Load Balancer This challenge is to build your own application layer load balancer. A load balancer sits in front of a group of servers and routes client requests across all of the serv...

Remember to Delegate: The Triangle of Trust

By
So you think you can lead a team? I’ve been talking and writing a lot about leading a software engineering team in 2025. I started thinking about it more deeply the year before when I decided to give a colleague, who was moving into team leading, some advice: 'Doing the work' isn't the only way to add value Remember to delegate Pick your battles Talk to your team every day Out of this came a talk, “So you think you can lead a team?” which I gave at work, at meetups and at conferences in various different formats during the first quarter of 2025. Here I am looking at Remember to Delegate and an idea which came out of discussion around the talk, The Triangle of Trust, in more detail. Delegate Delegation is a crucial skill for any team lead, yet it is often one of the most challenging aspects of leadership to master. Many leaders, particularly those who have risen through the ranks as individual contributors, struggle to let go of tasks, fearing a loss of control or a dip in ...

Catalina-Ant for Tomcat 7

By
I recently upgraded from Tomcat 6 to Tomcat 7 and all of my Ant deployment scripts stopped working. I eventually worked out why and made the necessary changes, but there doesn’t seem to be a complete description of how to use Catalina-Ant for Tomcat 7 on the web so I thought I'd write one. To start with, make sure Tomcat manager is configured for use by Catalina-Ant. Make sure that manager-script is included in the roles for one of the users in TOMCAT_HOME/conf/tomcat-users.xml . For example: <tomcat-users> <user name="admin" password="s3cr£t" roles="manager-gui, manager-script "/> </tomcat-users> Catalina-Ant for Tomcat 6 was encapsulated within a single JAR file. Catalina-Ant for Tomcat 7 requires four JAR files. One from TOMCAT_HOME/bin : tomcat-juli.jar and three from TOMCAT_HOME/lib: catalina-ant.jar tomcat-coyote.jar tomcat-util.jar There are at least three ways of making the JARs available to Ant: Copy the JARs into th...
