| 3 | * HSQLDB is a very simple database to configure as you don't need to install nor to start it before being able to use it. It comes as a single JAR file named ##hsqldb*.jar##. If your XWiki WAR doesn't have it in ##WEB-INF/lib## you'll need to download it and copy it there. You can download it from the [[HSQLDB web site>>http://hsqldb.org/]] or directly from the [[Maven Central Repository>>http://repo1.maven.org/maven2/hsqldb/hsqldb/]]. | ||
| 4 | * Once this is done, you need to configure XWiki to use HSQLDB and to tell it where the database files will be created. To do this, edit the ##WEB-INF/hibernate.cfg.xml## file where you have expanded the XWiki WAR file and uncommented the HSQLDB part. | ||

| 7 | If you intend to use HSQLDB in production you should probably tune it for a production usage. If you've installed the XWiki standalone distribution just be aware that it's not tuned to be production-ready. Also note that you would need to find a way to perform backups, live replication, administration tools etc. We would suggest using a more production-ready database such as MySQL or PostgreSQL if you can. | ||

| 12 | * You can use a remote HSQLDB database instead of embedding it. To do this, just use a URL like ##jdbc:hsqldb:hsql:HOSTNAME...## instead of the ##jdbcc:hsqldb:file:..## URL. The major version of the hsqldb jar file must match the major version that the HSQLDB server is using. | ||
| 13 | * If you want to use your app server facilities to manage your data sources (generally a better strategy), then you must follow these steps: | ||
| 14 | ** Put the ##hsqldb*.jar## file into your app server class path instead of in your web app (like in ##$CATALINA_HOME/common/lib##) | ||
| 15 | ** In ##hibernate.cfg.xml##, use the following settings in place of the HSQLDB block in the sample file. Specifically, do not set the url, user, etc. here and leave the provider_class unset (i.e. use the default value), since XWiki's implementation does not handle container-managed data sources:((( | ||
| 16 | {{code}} | ||
| 17 | <property name="connection.datasource">java:/comp/env/jdbc/xwiki</property> | ||
| 18 | <property name="dialect">org.hibernate.dialect.HSQLDialect</property> | ||
| 19 | {{/code}} | ||
| 20 | ))) | ||
| 21 | ** the final step is to manage the data source using app server facilities. With Tomcat, for example, you would map the //resource link// ##jcbc/xwikiDs## to a container-managed data source using the Admin web app or by editing the file ##conf/Catalina/*/xwiki.xml## (i.e. webapp-name + ".xml"). |
