A content repository is an information management system that provides various services for storing, accessing, and managing content. In addition to a hierarchically structured storage, common services of a content repository are versioning, access control, full text searching, and event monitoring.
Apache Jackrabbit – Building Jackrabbit
A content repository is not a content management system CMSalthough most existing CMSs contain a custom content repository implementation, often based on the file system or a relational database. Please ask questions on the Jackrabbit mailing lists. There is the users list for questions around using JCR and Jackrabbit and the dev list for the development of Jackrabbit documentztion and for people starting to extend Jackrabbit or other advanced topics.
See the Building Jackrabbit page for detailed build instructions. For Jackrabbit features like access control and node type management not covered by the Jacmrabbit API, see the Examples page on the wiki, the Jackrabbit javadocs, or contact the Jackrabbit mailing list.
See the mailing list announcement for a simple example on using the JTA support in Jackrabbit. For a more complete explanation of the transaction features, please see section 8.
Apache Jackrabbit – Jackrabbit Roadmap
You can create a new workspace either manually or programmatically. The manual way is to create a jacorabbit workspace directory within the repository home directory and to place a new workspace. See the Jackrabbit Configuration page for configuration details.
Note also that you need to restart the repository instance to access the new workspace. You can then use the createWorkspace String method to create new workspaces. There is currently no programmatic way to delete workspaces. You can delete a workspace by manually removing the workspace javkrabbit when the repository instance is not running.
Getting Started with Apache Jackrabbit
See the JAAS documentation for configuration instructions. The current JackrabbitSimpleAccessManager class only supports three access levels: Anonymous users have read access while normal and system users have full read-write access. You need to implement a custom AccessManager class to get more fine-grained access control. A persistence manager PM is an internal Jackrabbit component that handles the persistent storage of content nodes and properties.
Each workspace of a Jackrabbit content repository uses a separate persistence manager to store the content in that workspace. Also the Jackrabbit version handler uses a separate persistence manager.
The persistence manager sits at the very bottom layer of the Jackrabbit system architecture. Reliability, integrity and performance of the PM are crucial to the overall stability and performance of the repository.
In practice, a persistence manager is any Java class that implements the PersistenceManager interface and the associated behavioural contracts. Jackrabbit contains a set of built-in persistence manager classes that cover most of the deployment needs.
There are also a few contributed persistence managers that give additional flexibility. A Jackrabbit file system FS is an internal component that implements standard file system operations on top of some underlying storage mechanism a normal file system, a database, a webdav server, or a custom file format. A file system component is any Java class that implements the FileSystem interface and the associated behavioral contracts. File systems are used in Jackrabbit both as sub-components of the persistence managers and for general storage needs for example to store the full text indexes.
The persistence manager interface was never intended jaxkrabbit being a general SPI that you could implement in order to integrate external data sources with proprietary formats e. The reason why we abstracted the PM interface was to leave room for future performance optimizations that would not affect the rest of the implementation e. A persistence manager should not be intelligent, i. The jackarbbit thing it should care about is to efficiently, consistently, and reliably store and read the content encapsulated in the passed NodeState and PropertyState objects.
Make sure you changed existing workspace. The workspace element in repository. Verify that you also put the jar files into the classpath that jackrabbit depends on for text extraction. Go to the downloads page to get the war file. Some documents may still not be searchable for various reasons: Jaxkrabbit text from binary content is only indexed on the parent node of the jcr: Instead you can use the following:.
The context node of an XPath query is the XML node relative to which the query expression is evaluated. This means that one should not include jcr: Forcing a consistency check may be useful when you think the index is inconsistent.
You need to add two parameters to the SearchIndex section in the workspace. Then uackrabbit Jackrabbit and watch the log file for possible repair messages. A JCR implementation may return -1 when the size is unknown. If you still want a size information you can append an order by clause to your statement.
This will force Jackrabbit to calculate the result size. What is a content repository? Javkrabbit is Apache Jackrabbit? What do I do if I have a question? How do I use transactions with JCR? How do I create new workspaces in Jackrabbit? How do I delete a workspace in Jackrabbit?
