At the time it didn't seem like there was a way to do it, but I have come up with a way through a new feature found in JDK 1.4. Below is an example CFC that has a single method, which determines who called it and what method it is. <cfcomponent> <cffunction name="getCaller" returntype="struct" access="public"> <cfscript> e = CreateObject("java", "java.lang.Exception"); sts = e.getStackTrace(); foundme = false; theCaller = StructNew(); for(itr = 1; itr lte ArrayLen(sts); itr = itr + 1) { className = sts[itr].getClassName(); if(foundme and className contains "2ecf") { index = Find("2ecf", className); theCaller.from = Mid(className, 3, index - 3); break; } if(not foundme and className contains "2ecfc") { foundme = true; methodName = sts[itr].getClassName(); index = Find("$func", methodName); theCaller.toMethod = Mid(methodName, index + 5, Len(methodName)); } } </cfscript> <cfreturn theCaller> </cffunction> </cfcomponent> Again, the above only works in JDK 1.4. There is a way to make it work with earlier JDKs, but that would be more time consuming both from a development point of view and a performance one. I also blogged this at http://devilm.com/archives/000044.html.
