Answer 1

Make sure You have valid jar/driver in your project classpath.
Open new Mule Project in Studio, and then follow these steps to add/create a datasource in mule flow:
a. Import the driver
b. Create a Datasource,
c. Create a Connector that uses our Datasource, and finally
d. Create a simple flow that uses our connector.
It seems you are missing driver jar in project classpath.
How to Import the Driver?
Once you have the jar file(you can download jar respective to sqllite from some repo ,eg- maven_repo), the next steps are very simple:
In the Package Explorer,
Right-click over the Project folder
Look in the menu for Build Path > Add External Archives…
Look for the jar file in your hard drive and click Open.
Now you should see in the package explorer that the jar file is present in “Referenced Libraries.”
This will allow you to create an insta
nce of the Object driver you will need.

It's probably a classpath issue. If you are using Maven with your project, simply add the dependency in your pom.xml (and right click on your project > Mule > Update project dependencies):
<dependency>
<groupId>org.xerial</groupId>
<artifactId>sqlite-jdbc</artifactId>
<version>3.20.1</version>
<scope>test</scope>
</dependency>
Make sure you understand how Maven works and how to manipulate your pom.xml file. Maven getting started and POM Introduction might help.
If you are not using Maven, you need to manually import the dependency in your classpath. #Malesh_Loya answer should help.
