LiferayA portlet that connects to MySQL in the local environment and outputs elements of the table.

I was trying to use the JDBC driver to display the acquired value in jsp, but
I looked it up and found that it is common to use Service Builder to retrieve and display values.

I even set the table definition information in service.xml, but
I took time to find out what to do from there, but I don't know.

I would appreciate it if you could let me know if there are any web pages to help me realize it.

Thank you for your cooperation.
