The Hello World example uses standard
GemFire configuration and application files.
You can find these files under the helloworld directory in your examples installation.
gemfire.properties is the Pivotal GemFire system configuration file. Use it to define how processes in a GemFire system (in the Hello World example, two Java applications) find each other and communicate.
The xml/HelloWorld.xml file is the declarative XML configuration for the Pivotal GemFire cache. Use this file to set up general cache facilities and behavior and to create and initialize cached data regions.
