Get instance name in ColdFusion 10

Question

How can I get the name of the ColdFusion instance ("cfusion" for example) in ColdFusion 10?

Pre-10 you could do so by using the jrun java object:

<cfobject action="create" type="java" class="jrunx.kernel.JRun" name="jr">

#jr.getServerName()#

But since Jrun has been replaced by Tomcat I need to find a new way of getting the instance name.

I know it can be done using the admin api but that does not work for me because of security issues.

Answer 1

look in the server scope. There is a value at server.coldfusion.rootdir. On CF10 this is the directory of the instance. So for the "cfusion" instance on my Mac for example, this value is /Applications/ColdFusion10/cfusion. You could grab the last directory namd in the path and that is the name of the instance. Not exactly elegant, but might get you what you need.

Answer 2

There is a "runtime" component in the Admin API in CF10. You can get the instance name with this snippet of code:

var runtime = createObject("component", "CFIDE.adminapi.runtime");
instance = runtime.getInstanceName();

This should return the same value as getServerName() used to in the jrunx.kernel.JRun component.

Answer 3

This should work:

<cfset inetAddressObj = createObject("java", "java.net.InetAddress") />
<cfset machineName = inetAddressObj.localhost.getCanonicalHostName() />
