Can I have a index.html in a maven project?

I am new to Java and I have a Java application with Maven.

I have index.html file that opens a question to the user. If the user says "Yes" it opens another HTML file called form.html.

I created a file called insertData.java that connects with my DB.

However, when I click on my submit button on form.html it opens the insertData.java with my code and does not post the data on the DB.

Also, why in a Maven project when I try to run my project the index.html only has the option view?

When I try to run the project it goes to java file and not to my HTML file.

I changed my InsertData to JSP and now it does not add data on the DB.
