I have a java (desktop) application that does some operations in writing the logs to a table in Mysql, I need to do a page that will show me this log.
I did some tests, but did not succeed. I am using Tomcat 9 and eclipse to run.

@Henrique already tried to import manually, and even by Maven. I edited the topic and includes pom.xml. The error continues :(
