Welcome to Apache Jackrabbit

Apache Jackrabbit needs two pieces of information to set up a runtime content repository instance:. Repository home directory The filesystem path of the directory containing the content repository accessed by the runtime instance of Jackrabbit. This directory usually contains all the repository content, search jackfabbit, internal configuration, and other persistent information managed within the content repository.

Note that this is not absolutely required and some persistence managers and other Jackrabbit components may well be configured to access files and even other resources like remote databases outside the repository home directory. A designated repository home directory is however always needed even if some components choose to not use it. Jackrabbit will automatically fill in the repository home apaache with all the required files and subdirectories when the repository is first instantiated.

Repository configuration file The filesystem path of the repository configuration XML file. This file specifies the class names and properties of the various Jackrabbit components used to manage and access docummentation content repository.

Jackrabbit Roadmap

Jackrabbit parses this configuration file and instantiates the specified components when the runtime content repository instance is created. These two configuration parameters are passed either directly to Jackrabbit when creating a repository instance or indirectly through settings for a JNDI object factory or some other component management system. For each workspace that was created, there will also be a workspace. You can also manually create the workspace folder with a workspace.

The repository configuration file, typically called repository. A default workspace configuration template is also included in the repository configuration file. The exact format of this XML configuration file is defined in the following document type definition DTD files published by the Apache Jackrabbit project.

Of course you will need to make configuration changes if you want to enable new features like the data store introduced in Jackrabbit 1. The top-level structure of the repository configuration file is shown below.

Starting with Jackrabbit 1. See the Jackrabbit 1. It is a good idea to place the repository.

Jcakrabbit keeps your repository and its configuration nicely contained within a single directory tree. Most of the entries in the configuration file are based documentatiob the following generic JavaBean configuration pattern. Such configuration specifies that the repository should use an instance of the specified class with the specified properties for the named functionality.

These variables can be used to avoid hardcoding specific options in the configuration files. The following variables are available in all Jackrabbit versions:. Jackrabnit security configuration element is used to specify authentication and authorization settings for the repository.

The structure of the security configuration element is:. If JAAS authentication is not available or as is often the case too complex to set up, Jackrabbit allows you to odcumentation a repository-specific JAAS LoginModule that is then used for authenticating repository users. The default SimpleLoginModule class included in Jackrabbit implements a trivially simple authentication mechanism that accepts any username and any password as valid authentication credentials.

Once a user documentatiom been authenticated, Jackrabbit will use the configured AccessManager to control what parts of the repository content the user is allowed to access and modify. The jackrqbbit [SimpleAccessManager http: A Jackrabbit repository contains one or more workspaces that are each configured in a separate workspace.

The Workspaces element of the repository configuration specifies where and how the workspaces are managed. The repository configuration also contains a default workspace configuration template that is used to create the workspace.

See the createWorkspace methods in the JackrabbitWorkspace interface for more details on workspace creating workspaces. The following global workspace configuration options are specified in the Workspaces element:. The workspace configuration template and all workspace. To modify the configuration of an existing workspace, you need to change the workspace.

The version histories of all versionable nodes are stored in a repository-wide version store configured in the Versioning element of the repository configuration. The versioning configuration is much like workspace configuration as they are both used by Jackrabbit for storing content.

The main difference between versioning and workspace configuration is that no search index is specified for the version store as version histories are indexed and searched using the repository-wide search index.

Instead the native file system path of the version store is explicitly specified in the configuration.

See the Search page on the Jackrabbit wiki. The Persistence Manager is one of the most important parts of the configuration, because it actually takes care of storing the nodes and properties.

There are various very different implementations, but most of them are using databases to store the data. If you use a database PM and like to connect to an external database, you might also have to setup the database. For large binary properties there is the option to use the DataStore instead of the Persistence Manager.

If you use a database persistence manager, the configured database connection must not be under the control of an external transaction manager. Jackrabbit implements distributed XA transaction support on a higher level, and expects to be in full control of the underlying database connection.

Early versions on Jackrabbit were designed to abstract their persistence mechanism using a virtual file system layer defined in the FileSystem interface. However, certain parts of Jackrabbit still use this file system abstraction.

The recommended alternative is to use the LocalFileSystem implementation that simply maps abstract file system accesses to the specified directory within the native file system.

See the Clustering page on the Jackrabbit wiki. See the DataStore page on the Jackrabbit wiki. When using a database-backed persistence manager or another component, you usually need to include the database password in Jackrabbit configuration.

Jackrabbit will automatically decode such a password before passing it to the underlying database. Jackrabbit Configuration Apache Jackrabbit needs two pieces of information to set up a runtime content repository instance: Repository configuration The repository configuration file, typically called repository.

Bean configuration elements Most of the entries in the configuration file are based on the doccumentation generic JavaBean configuration pattern. The following variables are available in all Jackrabbit versions: Only available in workspace configuration. Security configuration The security configuration element is used to specify authentication and authorization settings for the repository. The structure of the security configuration element is: Workspace configuration A Jackrabbit repository contains one or more workspaces that are each configured in a separate workspace.

The workspace settings in the repository configuration file are: Versioning jackrabit The version histories of all versionable nodes are stored in a repository-wide version store configured in the Versioning element of the repository configuration.
