The links on this page lead to version 2006.3a of the HTTP-CEC.
The HTTP-CEC component is supplied as a J2EE web-application in a WAR file (http://www.astrogrid.org/maven/org.astrogrid/wars/astrogrid-cea-http-2006.3a.war). Download the WAR file to the computer where you want to run the web-application.
There is also an installer programme, available as an executable JAR-file. Use of this installer is not currently recommended and is not documented in these pages.
