I copied the below code(versioningBasics method) from
http://wiki.apache.org/jackrabbit/ExamplesPage examplesPage and I am
calling it with:
<snip>
Repository repository = new TransientRepository();
Session session = repository.login(new
SimpleCredentials("username",
"password".toCharArray()));
try {
Node root = session.getRootNode();
versioningBasics(root, session);
</snip>
private static void versioningBasics (Node parentNode, Session session)
throws RepositoryException
{
//create versionable node
Node n = parentNode.addNode("childNode", "nt:unstructured");
n.addMixin("mix:versionable");
n.setProperty("anyProperty", "Blah");
session.save();
Version firstVersion = n.checkin();
//add new version
Node child = parentNode.getNode("childNode");
child.checkout();
child.setProperty("anyProperty", "Blah2");
session.save();
child.checkin();
//print version history
VersionHistory history = child.getVersionHistory();
for (VersionIterator it = history.getAllVersions(); it.hasNext();)
{
Version version = (Version) it.next();
System.out.println(version.getCreated().getTime());
}
//restoring old version
child.checkout();
child.restore(firstVersion, true);
}
This is the exception I get, what am I doing wrong?
