Thanks to Jeromy and Ted , your comments definitely help me a lot. I looked through the YUI website, the widgets are quite rich. I still concern about if I want to use the Struts2 + YUI, I have to know pretty much about the YUI , right? Is YUI easy to learn and use? Since our developers don't know much about javascript.
And about GWT+ Struts2, I think the html code compiled by GWT is hard to read. And if I only want to use ajax for partical page, is there any issue? How do you think of this? There is a JSF plugin for struts2, the developer can develop web page using JSF component. There is a sample is about integrating struts2+jsf+facelets http://raibledesigns.com/rd/entry/integrating_struts_2_jsf_facelets. >From the comments, we can use the Ajax4jsf, and I find the RichFaces library has the ajax support and provides many function. Seems that the developers don't need to write javascript when using that ajax tag. Is there anyone success with this way? And how do you think?
