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.

A File node is a different type of node than the normal node that we created in the above step. The result of this statement is the line “Hello, World! Jackrabbit architecture and Deployment Models Find out more about the Jackrabbit Architecture or learn more 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.

The session is used to interact with the repository. The Repository interface contains some constants that can be used to query information using this method. Currently there are only guest and simple credentials included with the version we are using. Try the must-have graph OLAP database for those demanding the fastest graph analytics and data management solutions. The best practice for deploying Jackrabbit is to use JNDI or some other configuration mechanism in a container environment to keep the application code free of direct Jackrabbit dependencies, but since we are creating a simple standalone application we can take a shortcut by using the JcrUtils class from Jackrabbit commons.

Once we create the repository, we can use javax.

Apache Jackrabbit is an open source project and welcomes all contributions. There are property types for storing strings, numbers, dates, binary streams, node references, etc.

Dependance upon proprietary databases has changed. Apache Jackrabbit is the reference implementation of the Java Content Repository. Getting Started with Spark and Redis. In our code above we just did 1,2 and 6. Thus there is no need for explicit repository shutdown as long as all sessions are properly closed. Properties can be accessed using the Node.

If you are interested in using Jackrabbit, you should check the Jackrabbit architecture and try out the First Hops examples we have prepared.

If an incoming node has the same identifier as a node already existing in the workspace then the already existing node and its subgraph is removed from wherever it may be in the workspace before the incoming node is added.

A simple way to access the root node is to call the Session. Having a reference to the root node allows us to easily store and retrieve content in the current workspace.

The path syntax follows common file system conventions: The SimpleCredentials constructor follows the JAAS convention of representing the username as a normal String, but the password as a character array, so we need to use the String. You can use the system properties org.

Now, let’s start with some real code to see how we can create a repository with MongoDB. If you like, you could even split the example application into three pieces for respectively storing, retrieving, and removing the example content. As discussed in the First Hop example, a login with GuestCredentials returns an anonymous read-only session in the Jackrabbit default configuration.

Running this example should produce the following output:. You can also compile and run this class just like you did in the first hop example. Oak Storage Flavors Oak comes with two node storage flavors: This means developer decisions on how apachhe access a specific feature may be confusing or provide too many options to them.

The try-finally idiom is a good way to ensure that a resource really gets released, as the release method gets called even if the intervening code throws an exception or otherwise jumps outside the scope for example using a return, break, or continue statement.

The FirstHop example is a simple standalone application that fits nicely in the main method and lets jacmrabbit JVM take care of the possible exceptions.

java – How to learn using content repository and Apache JackRabbit? – Stack Overflow

We can iterate over the VersionIterator to get specific versions and its properties. 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. The actual implementation depends on the jar files available on the classpath and in this example is a TransientRepository. Sign up using Email javkrabbit Password.

But lets look at what we accomplished in this code. Now lets open up our IDE and import this project tuotrial whatever you like. So whats all this? You’ll get a few tips on how to use it in a Web application.

Repository represents a content repository stored in MongoDB.
