I am new to PySpark and I am learning to read a local SQLite db file using PySpark in Jupyter notebook. I am using PySpark 3.5.1. The db file and the notebook were in the same folder. I used the following code

spark = SparkSession.builder 
    .appName('Ops') 
    .config("spark.jars", "mysql-connector-j-8.4.0.jar") 
    .getOrCreate()

df = spark.read.format('jdbc') 
    .options(url='activities.db', dbtable='activities', driver='com.mysql.jdbc.Driver') 
    .load()

I had the following error message.

---------------------------------------------------------------------------
IllegalArgumentException                  Traceback (most recent call last)

      1 df = spark.read.format('jdbc')

    187     raise

How should I address the problem? Thank you!
