Copy the javax.servlet.jar file to C:\Program Files\Java\jdk1.6.0_20\jre\lib\ext\ (or equivalent)
Add this jar file to your project: Go to Project, Properties, Libraries and add the jar file as an "external jar file"

Go to: Windows -> Preferences -> Java -> Compiler -> Errors/Warnings
and under "Deprecated and restricted API" change the selection under "Forbidden reference" to "Warning" or "Ignore"

Compile it (this should happen automatically) (it won't run)
