I needed to uniquely identify a request to Pentaho (one particular action sequence request). Found a pretty darn easy way to do this with the help from Java RMI classes.

– Insert a Javascript data source

– Enter the following script

function getGUID() {
var VMID = new Packages.java.rmi.dgc.VMID();
return VMID.toString();
}
getGUID();

– Set return type as “string” for a new value

– Add it to your response

– Enjoy your GUIDs!

cef9372c035a42ed:-b0917ee:119a6d47d72:-7ff3
cef9372c035a42ed:-b0917ee:119a6d47d72:-7ff2

PS – I personally hate GUIDs when stored in the database. 🙂 However, for matching up with a particular request, yippeee!!
