Goodevening,

I need to retrieve lock_areas from CDO DB, because I want to know the user associated with a particular ID.

Very thank you,
cheers!

With "ID" are you referring to a durableLockingID like in CDOSession.openTransaction(String durableLockingID)?

Maybe you're looking for this server method:

org.eclipse.emf.cdo.common.lock.IDurableLockingManager.getLockArea(String)

You can find a usage example in org.eclipse.emf.cdo.internal.server.bundle.CDOCommandProvider.locks(CommandInterpreter):

protected void locks(final CommandInterpreter interpreter)
{
final InternalRepository repository = getRepository(interpreter,
"Syntax: cdo locks <repository-name> [<username-prefix>]");
final String userIDPrefix = nextArgument(interpreter, null);

new WithAccessor()
{
@Override
protected void doExecute(IStoreAccessor accessor)
{
repository.getLockingManager().getLockAreas(userIDPrefix, new IDurableLockingManager.LockArea.Handler()
{
public boolean handleLockArea(LockArea area)
{
interpreter.println(area.getDurableLockingID());
interpreter.println(INDENT + "userID = " + area.getUserID());
interpreter.println(INDENT + "branch = " + area.getBranch());
interpreter.println(INDENT + "timeStamp = " + CDOCommonUtil.formatTimeStamp(area.getTimeStamp()));
interpreter.println(INDENT + "readOnly = " + area.isReadOnly());
interpreter.println(INDENT + "locks = " + area.getLocks());
return true;
}
});
}
}.execute(repository);
}

If you need the infos at the client side you'll have to write a custom IQueryHandler and contribute it to the repository.

Cheers

Thanks for fast reply.
But I can't understand how get repository from my client application. I have repositoryInfo in my session, but I need the repository for getLockingManager.

You can't get access to the server-side IRepository (unless you use an embedded repository). I repeat my advice from the
previous reply:
