Resources in the jar package under Web-inf\lib in Servlet3.0 can be accessed directly from the browser

Looking at a project in the company, visited a path:

Http://127.0.0.1:8080/XXX/v2/jquery-1.8.1.min.js

But look at the Web resources in the project does not have this JS file, even v2 This directory is not, it feels strange

Then see if there is a corresponding filter in Web. XML to intercept processing, found that there is no, I wonder

Would like to be in the quoted Jar package, then open a few look under, sure enough to find, doubts

The directory structure is as follows:

Xxx.jar---com.abc---meta-inf------manifest.mf------Resources---------v2------------jquery-1.8.1.min.js

Summary: Resources in the jar package under Web-inf\lib in Servlet3.0 can be accessed directly from the browser, as in Webroot
