To install and run a HSQLDB in server mode proceed as follows:

  • Download the release from http://hsqldb.org.
  • Unzip it, e.g. C:\hsqldb-2.2.5\.
  • The HSQLDB-jar is then found at C:\hsqldb-2.2.5\hsqldb\lib\hsqldb.jar.
  • Create a batch file for starting the HSQLDB in server mode, e.g. C:\hsqldb-2.2.5\hsqldb\bin\hsqldbServer_start.bat with content:

@java -classpath ../lib/hsqldb.jar org.hsqldb.server.Server --database.0 file:../data/MH --dbname.0 MH_DB

  • This creates and starts a db with name MH_DB with db-files in the directory C:\hsqldb-2.2.5\hsqldb\data. You can start several databases at once, replace the batch file content with:

@java -classpath ../lib/hsqldb.jar org.hsqldb.server.Server --database.0 file:../data/MH1 --dbname.0 MH_DB1 --database.1 file:../data/MH2 --dbname.1 MH_DB2

  • You then can reach the HSQLDB via JDBC / JPA

driver: 'org.hsqldb.jdbcDriver'
url: 'jdbc:hsqldb:hsql://localhost/MH_DB'
user: 'SA'
pwd: ''

  • When using JPA with Hibernate then you can specify a dialect in persistence.xml (for other JPA providers, check the documentation):

<property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect" />
