DataServiceTransaction

[Former Community Member]

Hi,



I'm running lcds on Jboss.



I'm trying to add an object on the server and push it to the client using the DataServiceTransaction class.



I do so by writing these lines:



DataServiceTransaction dataTrans = DataServiceTransaction.begin(false);

dataTrans.createItem(destinatin name, createItem);

dataTrans.commit();



but when running, i get the follow exception on the first line:



Unable to locate a MessageBroker initialized with server id 'null'



does anyone know how can i solve it??



thanks,



Liat

Hi DJ,     I think you have to install and configure JOTM first, see  http://www.nabble.com/LCDS---Tomcat---JOTM-Integration-td18761900.html     Cheers!     Martin Zach
