On the Eclipse site, there are several Eclipse downloads, which one I should pick?
This – Eclipse IDE for Java EE Developers
This – Eclipse Classic 3.7.2
Or this – Eclipse IDE for Java Developers
Now I’m programming regular Java applications, 2d graphics (awt, graphics2d, etc..) and in the future JSP.
For general Java programming the Eclipse Classic would be appropriate.
If you want to do web development, then I suggest the Java EE variant, which is suitable for JSP (it also contains everything the Classic variant does).
