how do I set the debug configuration ?

Hi experts,

I have been trying hard to resolve this debugging issue with no avail.

Eclipse Oxygen is the IDE I am using.
This is a small web app with MVC, JPA and Hibernate and Maven. Database is Mysql.


The problem is that whenever I right click the jsp page which I need to debug on server, Eclipse does not switch to the debug perspective as like in the past.

I tried creating a customized perspective where I had the debug tools like step in, step over etc to appear in the toolbar but not successful.

I am seeking help as to how do I make Eclipse change to a debug perspective with all the debugging buttons appear.

When I first import the project into Oxygen, all the buttons appear but whenever I click to debug, all the buttons will just greyout.

Is there a bug there or ?

I am really lost and hope someone can advise me the how to.

Tks.
