I am trying to add postgres database connection to java spring application through JNDI. But while building the application, it shown an error " Error creating bean with name 'dataSource' defined in class path resource ".
This is my application.properties file.
spring.datasource.jndi-name=java:/TestDb
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true
#spring.jpa.properties.hibernate.dialect =
org.hibernate.dialect.PostgreSQLDialect
spring.jpa.hibernate.ddl-auto = none
NOTE: The application is build succesfully if change application.properties like below
spring.datasource.url=jdbc:postgresql://localhost:5444/test
spring.datasource.username=test
spring.datasource.password=test
The stacktrace is given.
o.s.w.c.s.GenericWebApplicationContext : Exception encountered during context initialization - cancelling refresh attempt:

Normally, you dont define a JNDI datasource
inside your application, but in your application container . Spring
uses an embedded Tomcat Server though, where JNDI is disabled by default.
The easiest way would be to use an external Application Server and modifying its configuration by adding a JNDI
configuration. With embedded tomcat, datasource configuration should be done using the spring.datasource
properties.
Here you can see how to configure an external Application Server (Tomcat):https://www.baeldung.com/spring-persistence-jpa-jndi-datasource
If you still want to use JNDI with embedded tomcat, you can see here how to do it: How to create JNDI context in Spring Boot with Embedded Tomcat Container
