jcr

I have a question regarding event listener. We have a event listener which listen to delete node event and perform some activity say "send email". While code review i found this, although this code is working fine i am not convinced with the session being handled here : @Activate protected void activate(ComponentContext context) { try{ final String path="/content/dam/"; Session session = repository.loginAdministrative(repository.getDefaultWorkspace()); observationManager = session.getWorkspace().getObservationManager(); observationManager.addEventListener(this, Event.PROPERTY_REMOVED, path,

When I am trying to set a property to my JCR node I am getting error javax.jcr.nodetype.ConstraintViolationException: No matching property definition: PROPERTY. I am a newbie to cq5. Please can someone help me to resolve this error? In jcr every node has a node-type (value of "jcr:primaryType"). Most node-types define a schema of properties that are allowed on that node. You cannot just add whatever property you like. It has to be defined in the schema. If you try to add and persist (commit) a property that is not defined, you get exactly this ConstraintViolationException . So here's what

When running Apache Jackrabbit JCR as an embedded service in your app, is there a quick way to get a sound and consistent backup of the contents of the Jackrabbit repository without shutting Jackrabbit down? If so how? See BackupAndMigration on the Jackrabbit Wiki for a list of options. I would recommend to use XML export (system view), as it is the simplest solution. Also, because it is part of the JCR standard, so it should work on other JCR implementations as well. Note that this approach has one drawback: it is currently not possible to re-import a full export, ie. from the root node and

I'm doing an academic research in trying to develop a programming tool that assists in implementing fine-grained locking functions, for concurrent programs that maintain tree-like data structures. For example, the programmer may write some functions that receive a tree root-node and modify the tree (by traversing on some routes and adding/removing nodes), and the tool will help him to find where in the code nodes should be locked and where they can be released - so the functions could be executed concurrently on the same tree. I am looking for some real-life code examples in which such fine

How to store images to jackrabbit and deliver those images to HTML pages? Ex. If user will upload multiple images from one HTML page then he should be able to see all those images in next html page or any other page when required This is the way: public class JackRabbitServiceImpl { Repository repository = new TransientRepository(); public JackRabbitServiceImpl() throws Exception{ Session session = repository.login( new SimpleCredentials("username", "password".toCharArray())); try{ InputStream stream = new BufferedInputStream(JackRabbitServiceImpl.class.getResourceAsStream("red_rose.jpg"));

I'm trying to get full-text search working with modeshape. I'm particularly interested in ranked results based on lucene index. Here is my repository configuration "indexProviders": { "lucene": { "classname": "lucene", "directory": "${user.home}/repository/indexes" } }, "indexes": { "textFromFiles": { "kind": "text", "provider": "lucene", "nodeType": "nt:resource", "columns": "jcr:data(BINARY)" } }, I noticed a lucene index created at the specified location. I added 10-15 filesc with varied number of occurrence of search term into repository, and tried searching using some words. I am printing
