How to raise an application error at SXI_MONITOR from Java Mapping

Dear gurus,

I’m working with PI 7.30 and I’ve a Java mapping which I’d like to stop when a certain field comes empty from ERP.

I mean during my code I’m checking if the field is empty and in case it is an exception is raised to flag the message to red at SXI_MONITOR.

Unfortunately I’ve been trying the classes StreamTransformationException , StreamTransformationRuntimeException,RuntimeException, Exception, etc.. but without success.

my code inside a method:

if(fName.equalsIgnoreCase("") || fFrmt.equalsIgnoreCase("")){

     thrownew RuntimeException("text");  

Does anyone knows how to achieve that?

Thanks in advance and regards,

Jorge
