Numerous kinds of content repositories are provided these days, some of them are Open source like Apache Jackrabbit while others are still closed source and. You could look also at Silverpeas code. It’s using Jackrabbit with some simple code to create nodes, browse them etc. For example take a look. Readers performing this tutorial have just finished an overview of Apache Jackrabbit and the JCR specifications and are looking for examples.

Welcome to your first hops into the world of Jackrabbit!

The path syntax follows common file system conventions: What did you do after going through the example page and wiki? Typically, content repositories act as jackrabhit storage engine for larger applications such as a content management system or a document management system.

Segment storage is optimized for max performance in standalone environments, whereas document storage is designed for scalability in clustered environments. It appears some directories were created for you and some new config files where placed in the root of the project automatically.

Having just basic knowledge of the JCR specification can make decisions much jackrabbiy solid on platforms that use paache. There are property types for storing strings, numbers, dates, binary streams, node references, etc. Now lets open up our IDE and xpache this project use whatever you like.

Self explanatory, but this is how we log out of a session. Since we use the TransientRepository class as the Repository implementation, this step will also cause the repository to be initialized.

We just want the single string value, so we use the Property. Similarly, we can restore a specific version of a content.

Getting Started with Apache Jackrabbit

The absolute path starts with a forward slash and contains all the names of the ancestor nodes in order before the name of the current node or property. You can also take a look at the various JCR and Jackrabbit applications to get an idea of what to do with a content repository. Apache Jackrabbit seems different from common server platforms in that using typical platforms you would download some packages and run them which would start up a tutorual.


Find out more about the Jackrabbit Architecture or learn tuhorial about the Jackrabbit deployment Options be it as an embedded content repository to be delivered with you are application, a shared repository for example in a J2EE environment or a classical content repository server setup.

However the Apcahe is a good place to start.

This will just speed some things up for us later. This will occur if the topmost element of the incoming XML has the same identifier as an existing node elsewhere in the workspace. If you like, you could even split the example application into three pieces for respectively storing, retrieving, and removing the example content.

Our login is using a set of Credentials another interface called SimpleCredentials.

Apache Jackrabbit is the reference implementation of the Java Content Repository. I would use the standalone version at this stage.

In our code above we just did 1,2 and 6. A session is needed to access any content within a repository. Removals are first stored in the session-local transient storage, just like added and changed content. Nodes and properties can be removed using the Item.

This code snippet creates two new nodes, called “hello” and “world”with “hello” being a child of the root node and “world” a child of the “hello” node. Both the removal and the new addition will be dispatched on save. Thus there is no need for explicit repository shutdown as long as all sessions are properly closed.

More substantial content applications could also be written as web application or EJB components with different setup and error handling patterns. The changes are written to the persistent repository storage and they become visible to all sessions accessing the same workspace. This hop has a lot of similarities with the Second Hop example: The actual implementation depends on the jar files available on the classpath and in this example is a TransientRepository. If you are interested in using Jackrabbit, you should check the Jackrabbit architecture and try out the First Hops examples we have prepared.

Start with the Examples page. Take a look at the Frequently Asked Questions or browse the archives of the user and development mailing lists see also the searchable archives at The Mail Archive, Gmane, and Nabble for answers to questions not covered by the documentation pages. The TransientRepository implementation will automatically initialize the content repository when the first session is started and shut it down when the last session is closed.
