Hi all,

I have been working in J2SE core for last two years, unfortunately ( I haven't worked in web UI frameworks ). but, i have been put in another project where i need to create UI for web application with Drag and drop , Tree views (more complicated for me). Please give me suggestions to choose a web UI framework which can be used to fulfill this requirement. FYI, i have started learning JSPs and servlets.

Thank you all,
