First download the correct version of Subclipse:

Download the Eclipse 2.x version

Extract the zip file and copy the two folders:

org.tigris.subversion.subclipse.core_0.9.3.3
org.tigris.subversion.subclipse.ui_0.9.3.3

To your plugins folder, in my case:

C:\\Program Files\\SAP\\JDT\\eclipse\\plugins

Fire up the developer studio and you should now have the subversion perspective available.

Menu: Window => Open Perspective => Other…

Select SVN Repository Exploring from the dialog.

Right click on the SVN Repository windows to add a new repository:

Menu: New => Repository Location…

You will now see the following dialog:

Simply enter your subversion server address and user/password if required.

You should now see your source code, right click on the Trunk folder of a project and select Check Out as Project.

Cogs will start turning and when finished you will have a shiny new project to play with.
