You started Ignite with default config xml file. By default all events are disabled and must be specifically enabled. So, start Ignite with “examples/config/example-ignite.xml”, as it was in example before your changes:

Ignite ignite = Ignition.start("examples/config/example-ignite.xml")

Or, you can create your own config and enable certain events in it:

<property name="includeEventTypes">
         <util:constant static-field=""/>
         <util:constant static-field=""/>
         <util:constant static-field=""/>
