I am connecting to mysql database using JNDI but on execution it ends up on throwing exceptions

These are exceptions I'm facing

java.sql.SQLException: Cannot create PoolableConnectionFactory (Public Key Retrieval is not allowed)

Caused by: java.sql.SQLNonTransientConnectionException: Public Key Retrieval is not allowed

Here is context.xml

<Context>
<Resource name="jdbc/project" 
auth="Container" type="javax.sql.DataSource"
maxActive="25" maxIdle="5" maxWait="10000"
username="Shubham" password="1234abc" 
driverClassName="com.mysql.cj.jdbc.Driver"
url="jdbc:mysql://127.0.0.1:3306/studyeasy_db?useSSL=false"/>
</Context>

This is servlet Demo2.java

I'm beginner please help me!

I'm glad that you joined stack overflow. This error has nothing to do with your Java code. The error code says:

java.sql.SQLException: Cannot create PoolableConnectionFactory (Public Key Retrieval is not allowed)

All you need to do is set up a username and password to connect to your database.
