In Eclipse I clicked File->New->Dynamic Web Project and I am following a tutorial for Jersey that now wants me to go and change something in web.xml file...but I can't even find this file. What is it I am doing wrong?

Follow below steps to generate web.xml in Eclipse with existing Dynamic Web Project
For gradle / maven project you can use src/main/webapp/WEB-INF folder by default:
- main
- - java
- - resources
- - webapp
- - - META-INF
- - - - context.xml
- - - WEB-INF
- - - - web.xml
If your deployment descriptor tab is disabled, then click on update libraries it will also do your work. It will create. Xml file in Web content
You can try this: right-click on the project and select Java EE Tools -> Generate Deployment Descriptor Stub. web.xml should be generated.
I think you are creating a project in the wrong way,I am going to post here in step by step
Step 1: File>>New>>Project>>Web>>Dynamic Web Project
Step 2: Enter Project Name>>Next>>Next>>
Step 3: Check the checkbox for Generate web.xml deployment descriptor
Step 4: Finish
Please follow this way you will get you web.xml file under WEB-INF folder
