库和lib文件夹之间的区别？ 我们如何将jar文件添加到lib文件夹？

Question

When i created the dynamic web project, i will have 2 folders with name Libraries and lib. So during the project i added .jar files as follows

Build Path --> Configure Build Path--> Libraries (tab) --> Add external JAR's -- > OK

When i do this, it will add files to Libraries, However i would like to add .jar files to lib folder.

I tried copying all .jar files from Libraries to lib, but it says

Copied .jar files directly to lib folder in directory structure, but i doesn't display in eclipse.

I would appreciate your suggestions and inputs.
