Use Eclipse for SimpleDB Development
Please download the repackaged SimpleDB source code. The original SimpleDB package is available from the author's website, but I strongly recommend that you use the repackaged version because I made several changes to make it easier to compile and easier to run. In particular:
After you download the repackaged SimpleDB source code, in Eclipse, select File -> Import ... -> Existing Projects into Workspace. Choose Select archive file, select the zip file you downloaded, then click Finish. Now simpledb should appear in Eclipse as a Java Project, which you can compile and run just like any other Java project.
