阅读更多关于 Best server-side framework for heavy AJAX Java application

问题 There are zillions of Java web application frameworks. 95% were designed before the modern era of AJAX/DHTML-based development, and that means these new methods are grafted on rather than designed in. Has any framework been built from the ground up with e.g. GWT + Extjs in mind? If not, which framework has adapted best to the world of forms with dynamic numbers of fields and pages that morph client-side? 回答1: Echo2 / Echo3 by Nextapp (www.nextapp.com) is totally awesome.

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year .
