error in build path

[christine clarin]

hi i am having this error in building one of my projects in eclipse:

"The project was not built since its build path is incomplete. Cannot find the class file for java.lang.Object. Fix the build path then try building this project"

how do i resolve this? i don't know why it can't recognize java.lang.Object since all the others do. thanks!

In Eclipse's menu toolbar, click on "Project" then click on "Properties".
Your project properties window should appear. On the left-hand side tree, click on "Java Build Path". There will be 4 tabs on the right-hand side window. Click on "Libraries". In my configuration, java.lang.Object is in the rt.jar provided by the JRE. Make sure you have a jar that has java.lang.Object in your libraries tab and that the jar exists (just in case you upgraded your JRE or something like that).
