GWTaculous – visual effects on the loose !

GWTaculous is open source visual effects library for application created in or based on GWT. It is based on other open source library –

scriptaculous which is javascript solution for visual effects and html object manipulations. At the first glance GWTaculous is a java wrapper for javascript functions (JSNI) in scriptaculous library. But in fact it is complete solution with full java API (visual effects, effect queues, animation GWT event handlers etc). Let alone documentation and use examples. It also contains some minor bug fixes and will be updated with new visual effects. You don’t even have to know javascript to use it. Bring life to your user interface with a single line of code !

New HTTP Logger Grails plugin

I've wrote a new Grails plugin - httplogger. It logs:

  • request information (url, headers, cookies, method, body),
  • grails dispatch information (controller, action, parameters),
  • response information (elapsed time and body).

It is mostly useful for logging your REST traffic. Full HTTP web pages can be huge to log and generally waste your space. I suggest to map all of your REST controllers with the same path in UrlMappings, e.g. /rest/ and configure this plugin with this path.

Here is some simple output just to give you a taste of it.

17:16:00,331 INFO  filters.LogRawRequestInfoFilter  - 17:16:00,340 INFO  filters.LogRawRequestInfoFilter  - 17:16:00,342 INFO  filters.LogGrailsUrlsInfoFilter  - 17:16:00,731 INFO  filters.LogOutputResponseFilter  - >> #1 returned 200, took 405 ms.

17:18:55,802 INFO  filters.LogOutputResponseFilter  - >> #2 responded with ''
