I have a project "A" and I need to call a class "c" from another project "B".

I have done the following. Click in "A" -->Properties -->Build Path --> and in one tab of Java Source I selected the project B. --> Accept

Now I can create objets of Class "c" but when I run the project I get "ClassNotFoundException"

Update,

I keep getting java.lang.ClassNotFoundException.

In "JSF" -->Properties -->Build Path --> Projects ---> I Added the Project:
