Mapping between ASP.Net and Java World

[sudhakarnraju]

have good experience with ASP.Net and am forced to move to Java [due to change in client]. Appreciate, if you can point to right technologies equivalents of below ASP.net areas. This would help steer my learning

UI
ASPX - Presentation Layer
.cs - Code behind - Presentation Logic and links to business layer

Web Server - IIS
Business components - built as class libraries (dlls) - c#
Data Access - ADO.Net

Enterprise Blocks - Logging and Exception Handling

Dev Environment - Visual Studio for all above

[Tolls]

Presentation is usually JSPs and Javascript.
Web Server - pick one...Tomcat, Websphere, Weblogic (and more).
Business components - java classes.
Data access - pick a framework or just use straight JDBC in its own data layer.
Environment - pick an IDE...Eclipse, Netbeans, IntelliJ (and more).
