And already in the browser if I write localhost:8080, main page Tomcat does not open, gives an error. How to fix it?
Looks like a configuration mismatch ( I won't count it as an issue ) . To resolve this, Goto server tab --> double click on the particular tomcat server --> Server Loaction --> Select Use tomcat installation ( take control of tomcat installation). Then re-start your server and you should be able to see the tomcat home page at http://localhost:8080
again.
