This article is based on the experience of Jan Swaelens, Software Architect at Sofico. He is responsible for automatic performance testing of the company's new web platform based on GWT and SmartGWT. Sofico is specialized in software solutions for automotive finance, leasing, fleet and mobility management companies.
Choosing GWT and SmartGWT over Other Technologies
About two years ago Sofico started a project to replace its rich desktop application (built with PowerBuilder) with a browseribased rich Internet application. The developers selected GWT and SmartGWT as core technologies to leverage their in-house Java expertise because they believed in the potential of what these (fairly) new technologies had to offer. Their goal was to replace the existing desktop client with a new one that ran in a browser. Their eyes where set on a better user experience and high degree of customization possibilities to give their customers the flexibility and adaptability that they need to run their businesses.
Need End-to-End Visibility into GWT Black Box
GWT was a great choice as they could soon deliver the first basic version. The problems started when trying to figure out what was actually going on in these frameworks in order to analyze performance problems reported by the first testers.
Requirement #1: Browser to Database Visibility to "understand" what's going on
Do you know what really happens when a page of a GWT application is loaded? No?! Neither did the developers from Sofico. Getting insight into the "Black Box" was therefore the first requirement because they wanted to understand: what really happens in the browser, how many resources are downloaded from the web server, which transactions make it to the app server, what requests are cached, where is it cached and how the business logic and data access layer implementation impacts end user experience.
The following screenshots show the current implementation using dynaTrace (sign up for the free trial), which gives the developers full visibility from the browser to the web, app and database server. The Transaction Flow visualizes how individual requests or page loads and services by the different application tiers are processed.
End-to-End Visibility gave the developers more insight into how their GWT Application really works and what happens when pages are loaded or users interact with certain features.
Developers love the timeline view as it is easy to see what work is done by the browser, where performance hotspots are and even provides screenshots at certain events

Requirement #3: Correlated Server-Side Performance Data
Requirement #4: Automation, Automation, Automation
Next Step: Real User Monitoring
After test automation comes production: You want to make sure to also monitor your real users and catch problems not found in testing
If you want to analyze your web site - whether it is implemented in GWT or any other Java, .NET or PHP Framework sign up for the dynaTrace Free Trial (click on try dynaTrace for free) and get 15 days full featured access to the product.

Data is an unusual currency; it is not restricted by the same transactional limitations as money or people. In fact, the more that you leverage your data across multiple business use cases, the more valuable it becomes to the organization. And the same can be said about the organization’s analytics. In his session at 19th Cloud Expo, Bill Schmarzo, CTO for the Big Data Practice at EMC, will introduce a methodology for capturing, enriching and sharing data (and analytics) across the organizati...

I'm a lonely sensor. I spend all day telling the world how I'm feeling, but none of the other sensors seem to care. I want to be connected. I want to build relationships with other sensors to be more useful for my human. I want my human to understand that when my friends next door are too hot for a while, I'll soon be flaming. And when all my friends go outside without me, I may be left behind. Don't just log my data; use the relationship graph. In his session at @ThingsExpo, Ryan Boyd, Engi...

The vision of a connected smart home is becoming reality with the application of integrated wireless technologies in devices and appliances. The use of standardized and TCP/IP networked wireless technologies in line-powered and battery operated sensors and controls has led to the adoption of radios in the 2.4GHz band, including Wi-Fi, BT/BLE and 802.15.4 applied ZigBee and Thread. This is driving the need for robust wireless coexistence for multiple radios to ensure throughput performance and th...

If you’re responsible for an application that depends on the data or functionality of various IoT endpoints – either sensors or devices – your brand reputation depends on the security, reliability, and compliance of its many integrated parts. If your application fails to deliver the expected business results, your customers and partners won't care if that failure stems from the code you developed or from a component that you integrated. What can you do to ensure that the endpoints work as expect...

Enterprise IT has been in the era of Hybrid Cloud for some time now. But it seems most conversations about Hybrid are focused on integrating AWS, Microsoft Azure, or Google ECM into existing on-premises systems. Where is all the Private Cloud? What do technology providers need to do to make their offerings more compelling? How should enterprise IT executives and buyers define their focus, needs, and roadmap, and communicate that clearly to the providers?
