EclipseLink JPA With Informix

EclipseLink JPA With Informix explains step by step details of setting / configuring Java Persistence JPA With EclipseLink And Informix

How To Configure EclipseLink JPA With Informix?

Java Persistence API, is a standard interface which wraps different ORM tools such as  Hibernate, EclipseLink, OpenJPA etc.

ie; you can able to change Hibernate implementation to EclipseLink implementation without changing the code base.

On this standalone JPA Example, we are using EclipseLink With Informix

If you want to configure EclipseLink JPA With Oracle, you can follow JPA Tutorial With EclipseLink

EclipseLink is popular open source ORM (Object Relation Mapping) tool for Java platform, for mapping an entity to a traditional relational like Oracle, MySQL, SQL Server, PostgreSQL, DB2, Derby etc

I am going to re-use JPA Tutorial With EclipseLink


You need to remove classes12.jar (Oracle driver) and add ifxjdbc.jar (Informix driver) into classpath

You can check below different database with Hibernate and EclipseLink examples

Database Driver class Jar name Examples
MySQL com.mysql.jdbc.Driver mysql-connector-java-5.1.25-bin.jar (exact name depends on version)
EclipseLink JPA With MySql
Hibernate JPA With MySql
HSQLDB org.hsqldb.jdbcDriver hsqldb.jar

Modify persistence.xml

persistence.xml file must be under src/META-INF (Please check below screenshot(project structure)

<persistence xmlns:xsi=""
  version="2.0" xmlns="">
  <persistence-unit name="test" transaction-type="RESOURCE_LOCAL">
      <property name="javax.persistence.jdbc.driver" value="com.informix.jdbc.IfxDriver" />
      <property name="javax.persistence.jdbc.url"    value="jdbc:informix-sqli://kodiak:9088/stores_demo:INFORMIXSERVER=demo_on" />
      <property name="javax.persistence.jdbc.user" value="username" />
      <property name="javax.persistence.jdbc.password" value="password" />
      <property name="eclipselink.ddl-generation" value="create-tables" />
      <property name="eclipselink.ddl-generation.output-mode" value="database" />
