Introduction

This document does:

• Relate only to release 0.14.4 of the demo package(s) and anything later in the 0.14 series.
• Explain what's going on in Jtrix from a practical perspective.
• Explain how to run your own Jtrix nodes.
• Explain how to run the Jtrix demos.

This document does not:

• Explain what Jtrix is or the technical terms it uses. For this, you are stongly advised to read Jtrix: How to write netlets from http://www.jtrix.org which introduces things much more slowly. See also the papers Jtrix: A technical overview, Platform specification or Jtrix: An introduction for everyone. You can use The Jtrix dictionary as a quick reference.
• Explain installation and compilation. See the packages themselves for that.
• Explain how to write Jtrix applications. See the papers on the site for that Programming with Jtrix: The Beatrix application framework and for lower level details Jtrix: How to write netlets.

We describe several ways to play with Jtrix:

1. Use a simple Jtrix service. (Section .)
2. Run your own nodes with a hosting service. (Section .)
3. Launch and run the skeleton application on a remote hosting service. (Section .)

   The skeleton application is a simple distributed, self-redundant message service. Its code is discussed in detail in Programming with Jtrix: The Beatrix application framework, available at http://www.jtrix.org/.

4. Run your own DNS server, HTTP server and servlet engine as Jtrix services. (Section .)

   The servlet engine Webtrix is based on the Tomcat Web server at http://jakarta.apache.org/tomcat. It is Tomcat set in the Jtrix environment, meaning that it is a full-spec servlet engine which can be configured to be dynamically scalable and redundant and it runs in conjunction with the DNS server and HTTP server. You can run several such servers together, add more at will, and as you kill them arbitrarily the others will take over. We have taken pains not to alter the original Tomcat servlet engine code at all.
