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 Jackrabbit repository with a default configuration will create an admin user when it is first initialized. Now, let’s start with some real code to see how we can create jackrwbbit repository with MongoDB.
You could look also at Silverpeas code. Java provides a content repository specification JCR that defines how to access content bi-directionally on a granular level within a content repository.
Apache Jackrabbit – Getting Started with Apache Jackrabbit
This deserializes an XML document and adds the resulting item subgraph as a child of the node at the provided path. The session is used to interact with the repository. 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 jackrabbig covered by the documentation pages.
This will occur if the topmost element of the incoming XML has the same identifier as an existing node elsewhere in the workspace. Jackrabbit returns “anonymous” by default. Tips to tutoroal and configure a fully secured enterprise database for personal data protection.

Such a split would not work unless we persisted the changes we make. You will see repository startup exceptions caused by the lock file if you apaceh to properly close all sessions or otherwise shut down the repository before leaving the process that accesses a repository.
I would use the standalone version at this stage. This hop has a lot of similarities with the Second Hop example: So starting the repository may not be that obvious at present time, but its really easy to do.
Running java classes or jar projects can be quite a chore when we are using Maven as our build tool.
Creating a Content Repository Using Jackrabbit Oak and MongoDB
Until the transient storage is persisted, the added node is only visible within the current session and not within any other session that is concurrently accessing the content repository.
Tika in Action by Jukka Zitting, Chris Mattmann
The actual implementation depends on the jar files available on the classpath and in this example is a TransientRepository. Creating Nodes Items or contents in node store are managed in nodes. Dependance upon proprietary databases has changed. Running this example should produce the following output:.
Alternatively, if you use the Apache Maven build system which we recommendyou can set up your first hops project with the following dependencies. If you are interested in using Jackrabbit, you should check the Jackrabbit architecture and try out the First Hops examples we have prepared.
This code snippet creates two jackrabbt nodes, called “hello” and “world”with “hello” being a child of the root node and “world” a child of the “hello” node. But lets look at what we accomplished in this code. Oak Storage Flavors Oak comes with two node storage flavors: A simple way to access the root node is to call the Session.
Both the removal and the new addition will be dispatched on save. Like the added nodes, also the property is first created in the transient storage associated with the current session. The Jackrabbit documentation is a bit all over jacjrabbit place.
The method removes jackrabbiit entire content subtree, so we only need to remove the topmost “hello” node to get rid of all the content we added before.
