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.

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...

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...

Do software engineering professionals still read? - survey results

By
  In order to gauge the potential audience for my book, So you think you can lead a team? , I conducted a small survey of my colleagues, co-workers and anyone from Linked. I read regularly, for work and pleasure, and assumed everyone else did too but did the responses I received confirm this? I polled 173 people, all within the software engineering field (including Product, etc), with a range of ages and years of experience in their role. What surprised me the most was that the majority of people, young or old, just starting or seasoned, still prefer reading physical books to blogs or e-readers. It also seemed that the older and more experienced were the most keen in learning more, and reading to expand or update their knowledge.  When it comes to reading habits between different roles the survey showed that software engineers and team leads read more regularly for their career than other roles, with 55 years old and over and 16+ years experience being the biggest readers over...
