Hi folks,
trying to use the ls command in Newton, I get
> neo4j-ls 0
got id: 0
Exception in thread "Console cmd: neo4j-ls/0"
java.lang.IllegalArgumentException: XaResourceManager is null

at java.lang.Thread.run(Thread.java:613)
Using the code for the command:
public void handle(CommandRequest request, CommandResponse response)
throws CommandException {
PrintWriter out = getOut(response);
System.out.println("got id: " + request.getArgs()[0]);
StringTokenizer tokens = new
StringTokenizer(request.getArgs()[0].toString(), " ");
String id = tokens.nextToken();
Transaction tx = Transaction.begin();
Node localnode = neo.getNodeById(Long.parseLong(id));
......
Any hints on why the XaResourcemanager is null? Neo is initiated it
seems, the store is there and the service availabe ...
The NeoService instance is retrieved from another bundle that only
exports org.neo4j.core.api. That should be sufficient to expose the
basic operations, and there is no CNFE.
