JSPs and html files are served by my Glassfish server in NetBeans, but not servlets. Latest NetBeans is configured to use JDK latest 13, and Glassfish is using Java EE 1.8
Error reported in the browser:
HTTP Status 500 - Internal Server Error
type Exception report
message
Internal Server Error
description
The server encountered an internal error that prevented it from fulfilling this request.
exception
javax.servlet.ServletException: Error instantiating servlet class com.example.NewServlet
root cause
com.sun.enterprise.container.common.spi.util.InjectionException: Error creating managed object for class: class com.example.NewServlet
root cause
java.lang.RuntimeException:
note The full stack traces of the exception and its root causes are available in the GlassFish Server Open Source Edition 5.1.0 logs.
Error reported on the server (note that it's always at line 1 of the sevlet class! this is where normally the package is declared):

Looking at the solution to a vaguely similar post, also tried adding a no-argument constructor:
public NewServlet() {
super();
}
