Hibernate JPA With Informix

Hibernate JPA With Informix explains step by step details of setting / configuring JPA With Hibernate And Informix

How To Configure Hibernate 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 Hibernate With Informix

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

Hibernate 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, Sybase, HSQL, Informix etc

I am going to resuse JPA Tutorial With Hibernate


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)

Modify persistence.xml

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

Here we are using hibernate.dialect as "org.hibernate.dialect.InformixDialect"

<persistence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
  version="2.0" xmlns="http://java.sun.com/xml/ns/persistence">
  <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="hibernate.dialect" value="org.hibernate.dialect.InformixDialect"/>
      <property name="show_sql" value="true"/>
      <property name="hibernate.temp.use_jdbc_metadata_defaults" value="false"/>
