Vaadin is a framework using GWT behind the scene. And for that it needs a WidgetSet, which is basically the definition of the widgets that you want to use on the client-side. If you are using the core widgets of Vaadin, you are good because the vaadin.jar ships with a default WidgetSet for all [...]

Embed for vaadin is a Vaadin add-on that allows you to start your Vaadin application directly from your IDE. In this article, we will explain the rationale of such plugin and how you could use it in your own Vaadin applications. [...] Spring 3.1 GA was announced early this month. One feature we have been looking for some time is the new environment abstraction with bean definitions profile. While this abstraction allows to configure the profiles to use in many different locations, we found useful to be able to customize this even further to suit our needs. This blog post contains a simple implementation showcase, available on github. [...] Stability and performance of a build is a critical point when a project dealing with a large codebase and is composed of many developers. A better stability can be achieved by limiting the amount of resources that are platform or environment dependent. Performance, when working on projects that are several years old, and have dozens developers working on it, can be regularly threatened by a significant growth of its codebase, making performance issues start arising in various areas. In this article, we will cover a configuration change that will help ensuring a better build stability, along with helping in performance (effects can be different depending or current tools used). [...] In a previous article, we have discussed how staging the data to process with a sequence number could help us to build partitions that can be executed concurrently. As explained in the documentation, the PartitionHandler is the component that knows about the mean to transport StepExecution requests to the actual worker(s). It basically sends [...] Spring Batch is a powerful batch framework in Java with obviously a close integration with the Spring framework. One core feature for us is the ability to stage the data to process for a particular batch instance. In this article, we will cover how data can be staged and the features that can be built on top of it. More specifically, we will cover how a partition can contain business chunks, i.e. a set of elements to process that are linked to another business concept. [...] A previous article was focused on Apache Camel aggregation component, its new JDBC persistent repository more precisely. The sample provided includes a unit test which uses multiple good practices to test Camel routes. Let’s analyse them one by one. Have a test spring context The main idea is to keep unit test as simple [...] Tools orchestration We have seen an overview of all necessary tools separately. A bash script file will orchestrate all tools together and will generate a report. This report is then uploaded on our intranet so every one can consult and comments the results. In our case we use a confluence specific command line tool [...] The aggregator is a powerful component in the Camel toolbox. Since version 2.6, it has been enriched with a new persistence capability. As shown in the article it is quite easy to use. Feel free to test/use it and tell us what you think about it. [...] The Flex framework provides the basic foundations for a module mechanism. To build truly modular, performant, pluggable applications we made a layer on top of it using a double swf-swc compilation mechanism and extensions inspired by Eclipse. This turns out to be a nice fit: it cleanly abstracts the lazy asynchronous loading, and making many parts of application pluggable becomes easy. [...] |
