Dear Carl,
Thanks for your help. I installed Tomcat version 9. Now the project
runs correctly.
Changing the context path to “/” however, interfered with the “It
works” root app of Tomcat, so I changed it back. I get the correct result of
the conversion servlet at the path http://localhost:8080/mavenproject3/convert.
Yours,
Peter
