Manually firing off the trigger "On Component Error" from a tJavarow

I would like to error out a tJavaRow with a condition in my code, is that possible to fire off the "On Component Error" with code?

Hi,
The Java code of the tJavaRow will be executed for each row. The tJavaRow is normally used as an intermediary component.
For your use case, you can use tJava component which is used to execute a piece of Java code as a separate subjob in most cases. The Java code will be executed only once.

Am I missing something. The answer does not actually answer the question!

I also have a tJavaRow that gets information from a web service for each record that goes through it.

Is I get an error from the web service or it becomes unavailable I want to trigger an alternate execution path through a On Component error.

So how do I trigger this On Component error?

Hello

Which component you are using to fetch webservice ? If webservice failes you could attach onComponentError to it.

On tjavarow , you could throw runtime Exception to trigger oncomponenterror
E.g
throw new Exception(“manual error”)
Or int x = 10/a
If error , a=0 otherwise a=1
