Installing AJDT
To follow along with this article, you'll need to be running AJDT version 1.1.11 or later, which requires Eclipse 3.0 (final). There is an earlier version of AJDT available that works with Eclipse 2.1; however, many of the features we discuss in this article were added in version 1.1.11.

To install the latest AJDT for Eclipse 3.0, follow these steps:

1. Start Eclipse, then go to Help>Software Updates>Find and Install....
   
   
2. Search for new features to install and add a new remote site called AJDT Update Site with the URL http://download.eclipse.org/technology/ajdt/30/update.
   
   If you need a proxy server to access the Internet, set your proxy preferences via Window>Preferences>Install/Update.
   
   
3. Expand the AJDT Update Site node and select AspectJ. Choose to install the Eclipse AspectJ Development Tools, then read and accept the copyright statement.
   
   
4. Click Finish.

As of version 1.1.11, AJDT is fully integrated into the Eclipse 3.0 framework, so there are several ways to make sure that it is properly installed. The most useful of these is the AJDT documentation's integration with both the Eclipse help and the Eclipse Platform welcome pages. To navigate to both the AJDT help and the documentation for AspectJ 1.2 select Help>Help Contents. To see the AJDT additions, select Help>Welcome and choose any one of the Overview, Tutorials, Samples, or What's New links. In particular, following the Tutorials>Build a simple AspectJ application link activates the Simple AspectJ Application cheat sheet. Cheat sheets are a new feature in Eclipse 3.0, and the AspectJ cheat sheet extends the Java "Hello World" application detailed in the Java cheat sheet. (You can also access the cheat sheet by going to Help>Cheat Sheets and selecting the one you want.)
