You can use JMX to connect to the remote application server (it should be enabled in advance) and use the HotSpotDiagnostic MBean which allows taking a heap dump.
You can use JConsole or JVisualVM for invoking the MBean operation.
This post by Mike Haller describes how to use this method with JVisualVM.
