Hi everybody, I have tried many time to develop some UI application with connecting to database, but can not complete. Could some body help me? Thanks so much.

tamnc,

I would recommend you to go through our educational material here -
http://www.myeclipseide.com/index.php?module=htmlpages&func=display&pid=7
Also there are couple of EODs available. To access them, from MyEclipse IDE menu options click on MyEclipse > MyEclipse Start Page. This will open the start page. Click on [Example Projects]. You will find a lot of sample applications. I would recommend you to install MyBlogJSFJPAExample. Expand the project in package explorer and go through README.txt this will illustrate on how to run the sample project.
