Once you click Finish, Eclipse creates your Dynamic Web Project, and may ask whether you want to switch to the "J2EE Perspective." Once the project is created, you can see the myfacebookapp project in the "Project Explorer." Expand all of its folders to see the structure of your project.

Getting the Facebook Libraries

As mentioned at the beginning of this article, a group of independent Java developers have produced an unofficial but excellent set of Facebook libraries for Java development. Go to http://code.google.com/p/facebook-java-api/ to learn more about the project. These libraries need at least Java SE 5. They will not work with Java SE 1.4 or earlier.

You need to download the following JARs:

If you're running your Java app server on top of Java SE 5, download the following JARs as well:

You don't need the three JARs above if you're running on Java SE 6 or later.

Download the libraries and copy them to the myfacebookapp/WebContent/WEB-INF/lib folder on your disk. Once you copy the libraries to the folder, right-click the myfacebookapp project icon in the Eclipse Project Explorer and select "Refresh." Expand the "Web App Libraries" folder and Eclipse will show you the Facebook library jar files.
