Object Database
You can configure the central object database parameters in Jease/WEB-INF/web.xml.
Configure the database folder
The name of the database folder can be specified in two ways:
- If the database name doesn't include a slash, the database folder will be created directly in user home (prefixed by "db4o" or "perst", see below).
- If the database name includes a slash (java.io.File.separator), the value will be interpreted as path for the database folder. Please note: if a slash is present or not is determined by java.io.File.separator, so you'll need to specify paths with correct slashes according to your platform ("/" on Linux/Mac OS X, "\" on Windows).
Configuration for Linux / Mac OS X
<context-param> <param-name>JEASE_DATABASE_NAME</param-name> <param-value>/var/database/test/</param-value> </context-param>
Configuration for Windows
<context-param> <param-name>JEASE_DATABASE_NAME</param-name> <param-value>C:\database\test\</param-value> </context-param>
Please note: the specified folder contains all data, so if you want to make a backup of your CMS, simply backup the specified directory. That's it.
Configure the database engine
Jease supports the following open-source object-databases:
- db4o (jfix.db4o.engine.PersistenceEngineDb4o)
- Perst (jfix.db4o.engine.PersistenceEnginePerst)
- ZooDB (jfix.db4o.engine.PersistenceEngineZoodb)
db4o is the default engine. If you want to use Perst as engine, you can configure this in WEB-INF/web.xml:
<context-param> <param-name> JEASE_DATABASE_ENGINE </param-name> <param-value> jfix.db4o.engine.PersistenceEnginePerst </param-value> </context-param>
If you want to integrate another database with Jease, you can implement the interface for jfix.db4o.engine.PersistenceEngine. Please use existing implementations as guides.
