Re: Backup/Copy selected nodes

Hi,

To copy on the same repository, simply use Workspace.copy :
http://www.day.com/maven/javax.jcr/javadocs/jcr-2.0/javax/jcr/Workspace.html#copy%28java.lang.String,%20java.lang.String,%20java.lang.String%29

To copy to another repository, you need to export the nodes into an intermediary format, Jackrabbit
supports exporting and importing in XML. Use Session.exportSystemView and Session.importXML to
export/import nodes one by one.
http://www.day.com/maven/javax.jcr/javadocs/jcr-2.0/javax/jcr/Session.html#exportDocumentView%28java.lang.String,%20java.io.OutputStream,%20boolean,%20boolean%29
http://www.day.com/maven/javax.jcr/javadocs/jcr-2.0/javax/jcr/Session.html#importXML%28java.lang.String,%20java.io.InputStream,%20int%29

You can use PipedOutputStream and PipedInputStream to pass directly the XML from one repository to
another or use temporary files. Also, you may want to put different locks on nodes when exporting if you
allow concurrent accesses to your repositories.

Re: Jackrabbit Clustering in File System

Hi All,
Thanks for the reply. I am now using "BundleDbPersistenceManager"
along with File Data Store. This works fine in a clustered
environment.

how can roles/groups be distinguished from users?

> I am working on jackrabbit, how can roles/groups be distinguished from
users?

Speaking about Jackrabbit 1.6 (although I believe 2.0 is similar):

If you're talking about ACLs, then the recipient in each ACL is of type
java.security.Principal.  You can test if principals are instanceof
java.security.acl.Group.  This will tell you if the principal is a
group/role or not.

A org.apache.jackrabbit.core.security.principal.PrincipalProvider is
responsible for converting a String into a principal (or group).

Authorization in JackRabbit


It have seen that Jackrabbit has no "native" Authorization provided with it.  

From "Authorization" i want that a logged in user has permissions to
read/write/remove a: Node and/or property or even rights to login to a
workspace.

Are people implementing it by themselves on AccessMAnager??
or they using JeCARS to implement repository Authorization??
or some other pre-built product?

what others are witnessing with Authorization & permissions in JackRabbit?

This is not the case.

By default, login rights to a workspace are implemented by granting read
access to the root node in the workspace. Note that JCR and Jackrabbit
do not support the notion of per-property access control. You can,
however, separate the ability to modify properties from the ability to
add and remove child nodes.
