Now, I wanted to combine both to avoid having to implement my own security using Vaadin. The result I have so far can be found here: github project . I started from the shared security example given by vaadin4spring. I then added the Keycloak configuration as given by the keycloak-spring-security-adapter and the keycloak-spring-boot-adapter . I have now hit a wall in getting both to work together. When everything is up

I am planning to make an application that has views with complex forms and logical validation on the client side. I plan to use AJAX for submits and have some visual appeal. I want a recommendation from those who have experience developing with Bootstrap and/or CoffeeScript and Vaadin. I have two options: Using Bootstrap / CoffeeScript and some framework for the server site, such as Play Framework, Rails or Django Vaadin The criterion that concerns me is related to the complications that may arise in the client side JavaScript and/or HTML5 validation as well as in CSS and HTML code to be

I wanna switch my projects to spring-based product. My first step is to transform my java web application from a generated WAR file, to a standalone executable jar, powered by spring boot. Let's take a open source web application example from github.: Vaadin-Spring Web Application The web.xml file can be found here. The root-context file can be found here. I hope that there are some guides for me to perform the transformation. I have also submit an issue in the spring-boot project.

I have been working fine with Vaadin + Gradle + IntelliJ until yesterday night when I introduced SLF4J(logback) logging to my application. Since then I can't make my project anymore due to classDefFoundError of org/apache/tools/ant/util/ReaderInputStream .

I am using vaadin gradle plugin 0.9.5 and gradle 2.2.1 . Has anyone ever encountered this problem? I was reading another post where someone had the same

Can anyone suggest whether "GWT" or "Vaadin" are a better choice to design an application? Also: what are the differences in coding style? In GWT application logic is normally run on client side. It only calls server when it needs to read/save some data. In Vaadin application logic is on server side. Client side must normally call server after every user interaction. GWT advantage: App logic (replies to user interaction) is faster as it is run locally in the browser. It's also relatively insensitive to bad network conditions. Network is used only when needed (to read/save new data), which

I am torn between Wicket and Vaadin. I am starting a micro-isv and need to make a choice of web framework. I have narrowed down my choices to Wicket and Vaadin. I have used both frameworks and I love them both. however I need to make a choice. If If I choose Vaadin: I wont have to worry much about the look and feel. It comes with nice themes. I will do all my programming in Java which am very good at and wont have to spend time hacking CSS which am not very good at. And most of the components that I will need for a business applications are there OUT OF THE BOX including, desktop like layout,
