java web development

I am a novice in web development but I need to develop an application that will work in browser. But, the application should be like a destkop application. Application should implement simple functions like database table reflection, adding/deleting/updating table rows and calculating values based on formulas (I suppose here I should implement a java class that will make this calculations).

It seems to me I should use servlet+jsp but the application will not be static. Pages will always be refreshing. What java technologies I should use to implement my task? Maybe oracle ADF business componets in JDeveloper? Thanks!开发者_开发问答
