JSP Highcharts AND JAVASCRIPT

Question

Good morning I’m making a chart using the Highcharts library, I implemented it in a static way to perform the tests, but now I need to pass the information from the database to him. I read and saw that there are several ways, by XML, by Json. I wanted to know if anyone has used this library and what would be the best way to make this implementation.

I am using JSP with servelt I have already set the list that I will use in the graph as a parameter.

<!-- SCRIPT GRAFICO -->
    <script type="text/javascript">
    var chart = Highcharts.chart('grafico', {
