Learning Spring Faces, Security, Testing and Grail
Done with the four day training, finally! It’s pretty exhausting given that I had to get up two hours earlier to match the Central time schedule.
Spring Faces
I talked about JavaScript and AJAX two days ago. They are all good to some extent, but seemingly disconnected from the server. You have to think and manage the Web app as two pieces, bad for the productivity.
JavaServer Faces (JSF) technology was created to solve this problem. It a server-side framework, which provides GUI components, manages their states from the server side, handles events, and etc. You can then develop a web app more like the standalone application in some sense. Because JSF manages the state from the server side, it uses more resources and less performant than it’s JS/AJAX equivalent.
Spring Faces is not a replacement for JSF, but complements in the “Spring” way. It facilitates deeper JSF and Web Flow integration, manages JSF components’ states, and provides more lightweight JSF components. Therefore, you can get leaner web application than using pure JSF.
Debugging
Several tools can be handy for your debugging:
