Question: i need to add a jar file to a Liberty application in Bluemix. The WEB-INF folder is missing. How can i do that ? Thank you.

Answer: 
The WEB-INF folder shouldn't be missing, it should include at least your web.xml configuration file and your lib directory, where the liberty runtime is expecting to find the libraries you want to upload along with your application
Your java web application must have a WEB-INF directory.

See <http://docs.oracle.com/javaee/6/tutorial/doc/bnadx.html>

If you can't find it in your project, you can double click in your liberty in the bluemix console and inspect the liberty instance files, like this

WEB-INF should be at

app->wlp->usr->servers->defaultServer->apps->myapp.war->WEB-INF->libs
