 You can create a java server project that embeds Jetty and run it on [[metaarray|the MetaArray]] on your [[meta_port_allocation|assigned port]]. Below is a very simple example on how to get started with that. It doesn't use any IDE, so it's a bit manual. You can find more detailed directions at the external project links below. You can create a java server project that embeds Jetty and run it on [[metaarray|the MetaArray]] on your [[meta_port_allocation|assigned port]].
