Facing difficulty in configuring Sybase server with a fresh Spring boot application. Not sure how to configure Sybase server with spring boot successfully. Getting error "Cannot load driver class: com.sybase.jdbc4.jdbc.SybDriver".
Basically, I am looking to fetch some data from Sybase database and post as RESTful service in JSON format. Any help would be appreciated.

You can use spring boot jpa with sybase following this steps:
1.-Download jconn4.jar from the sap marketplace
2.-Install the jar in your local repository:
mvn install:install-file -Dfile="path-to\jconn4.jar" -DgroupId=sybase -DartifactId=jconn -Dversion=4_RELEASE -Dpackaging=jar
3.-Add the dependency to your pom:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>sybase</groupId>
<artifactId>jconn</artifactId>
<version>4_RELEASE</version>
</dependency>
4.-Add the database configuration to your application.properties:
spring.datasource.url=jdbc:sybase:Tds:HOST:PORT/DB_NAME
spring.datasource.username=USER
spring.datasource.password=PASS
spring.jpa.properties.hibernate.default_schema=SCHEMA
spring.datasource.driverClassName=com.sybase.jdbc4.jdbc.SybDriver
spring.datasource.type=com.zaxxer.hikari.HikariDataSource
spring.jpa.hibernate.ddl-auto=none
spring.jpa.databasePlatform=org.hibernate.dialect.SybaseDialect
spring.datasource.connectionTestQuery=select 1
spring.jpa.show-sql=true
Resolved: In pom dependency, instead of jpa, I used jdbc. And had to add 'jconn4d.jar' in the classpath externally.
