Managing Java Libs with Eclipse

Well I spend a bit of time figuring out how to add libraries to eclispe and finding the tomcat servlet libraries.

First I'll give the location of some key Tomcat jars

• $CATALINA_HOME/common/lib - required
• $CATALINA_HOME/server/lib - nice to have

If eclipse is having trouble resolving javax.servlet.HttpServletRequest or javax.servlet.HttpServletResponse you only need one library

  $CATALINA_HOME/common/lib/servlet-api.jar

1. Right click on the top level project folder
2. Click on "Build Path"
3. Click on "Configure Build Path"
4. A window pops up, in the dialog box pick the "Libraries" tab
   • click on "Add Library"
5. Another window pops up with a dialog box, select "User Libraries" and click next
6. The infocus window changes showing the existing libraries
   • click on "User Libraries"
7. The infocus window changes again, select "New"
8. enter the name of your library
9. Now select your new library and select "Add Jars"
   • go add your jars

I have two libraries, one for my local jars under WEB-INF/lib and one for the Tomcat common jars.
