java Source packages not available in the java web application?How can i get it?

[Shammikit]

So i started to learn about java servlets in university and i was able to create a servlet without any problem in the computer lab.however when i tried it in my home computer the folder source package is not there after creating a new web application. These are the step i followed:

 

New project > java web >web application > next > next > select server : glassfish server 4 > Finish 

so after following these steps a folder called source packages should be there,but it isnt there.(I will attach a image of the files available) 

 

if source packages folder is there i can continue with these steps:

right click source packages > new java package > finish

then i can create a servlet inside that package
