The JBoss Cache repository connector allows a JBoss Cache instance to be used as a JBoss DNA (and thus JCR) repository. This provides a repository that is an effective, scalable, and distributed cache, and is often paired with other repository sources to provide a local or federated repository.
The JBossCacheSource class provides a number of JavaBean properties that control its behavior:
Table 16.1. JBossCacheSource properties
| Property | Description |
|---|---|
| name | The name of the repository source, which is used by the RepositoryService when obtaining a RepositoryConnection by name. |
| cacheFactoryJndiName | Optional property that, if used, specifies the name in JNDI where an existing JBoss Cache Factory instance can be found.
That factory would then be used if needed to create a JBoss Cache instance. If no value is provided, then the
JBoss Cache DefaultCacheFactory class is used. |
| cacheConfigurationName | Optional property that, if used, specifies the name of the configuration that is supplied to the cache factory when creating a new JBoss Cache instance. |
| cacheJndiName | Optional property that, if used, specifies the name in JNDI where an existing JBoss Cache instance can be found. This should be used if your application already has a cache that is used, or if you need to configure the cache in a special way. |
| uuidPropertyName | Optional property that, if used, defines the property that should be used to find the UUID value for each node
in the cache. "dna:uuid" is the default. |
| retryLimit | Optional property that, if used, defines the number of times that any single operation on a RepositoryConnection to this source should be retried following a communication failure. The default value is '0'. |
| defaultCachePolicy | Optional property that, if used, defines the default for how long this information provided by this source may to be cached by other, higher-level components. The default value of null implies that this source does not define a specific duration for caching information provided by this repository source. |
| nameOfDefaultWorkspace | Optional property that is initialized to an empty string and which defines the name for the workspace that will be used by default if none is specified. |
| predefinedWorkspaceNames | Optional property that defines the names of the workspaces that exist and that are available for use without having to create them. |
| creatingWorkspacesAllowed | Optional property that is by default 'true' that defines whether clients can create new workspaces. |
