Configure HSQLDB in java web application

Here we will learn how to configure HSQLDB in Spring web application.

HSQLDB (HyperSQL DataBase) is the SQL relational db engine written in Java. It offers a small, fast multithreaded and transactional database engine with in-memory and disk-based tables and supports embedded and server modes. It includes tools such as a command line SQL tool and GUI query tools.

Current Release : 2.2.8 (Released January 2012)

Pre-Requisite :

JDK 1.6 (Separate download for JDK 1.5 is available)

hsqldb.jar (Included in Can be downloaded from here )

Spring JDBC 3.1 Jar

How to configure in Spring :

To configure HSQLDB, we need to add  configuration details in applicationContext.xml with other bean information.

<beans xmlns=""

 <!-- Below configuration has been added to enable in memory DB HSQLDB  -->
 <jd:embedded-database id="dataSource" type="HSQL">
	  <jd:script location="classpath:schema.sql"/>
	  <jd:script location="classpath:test-data.sql"/>


Here schema.sql contains the detail of DB that needs to be created by HSQLDB.



To populate the newly created DB test-data.sql script would be required.

insert into JBT_MEM values('20','AABBAABB','Address','NY','AB',23500);
insert into JBT_MEM values('20','BGDBCBDB','Address','City','State',23500);

Above created datasource can be used in combination of jdbctemplate and Hibernate. This datasource can directly be injected in dao layer to work with jdbctemplate.

 <bean id="SpringJdbcDao"  class="com.dao.SpringJdbcDaoImpl">
  <property name="dataSource" ref="dataSource"/>

To work with hibernate one more configuration would be required

 <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
     <property name="dataSource" ref="dataSource"/>
     <property name="hibernateProperties">
             <prop key="hibernate.dialect">org.hsqldb.jdbcDriver</prop>
             <prop key="hibernate.show_sql">true</prop>
  <property name="packagesToScan" value="com.beans"></property>
  <property name="mappingResources" value="JBTMem.hbm.xml"></property>


This session factory can now be injected in Dao layer.

<bean id="SpringHibernateDao"  class="com.dao.SpringHibernateDaoImpl">
  <property name="sessionFactory" ref="sessionFactory"/>
