The tLogCatcher component can catch exceptions from three types of components: tWarn, tDie, and

Java Exception. The tWarn component is used to trigger a warning message that can be caught by the

tLogCatcher component for an exhaustive log. The tDie component is used to stop the execution of a

job or a subjob and return an error code that can be caught by the tLogCatcher component for an

exhaustive log. The Java Exception component is used to handle any Java exception that occurs

during the execution of a job or a subjob and pass it to the tLogCatcher component for an exhaustive

log. The tLogCatcher component cannot catch exceptions from other types of components, such as

OnSubjobError Exception or tAssertCatcher. The OnSubjobError Exception is a trigger that is activated

when an error occurs in a subjob and can be used to perform some actions after the error, such as

sending an email or logging a message. The tAssertCatcher component is a component that collects

the assert data generated by the tAssert component and passes it on to the output defined. The

tAssert component is used to verify if a condition is true or false and generate an assert data

accordingly. Reference: Talend Open Studio: Open-source ETL and Free Data Integration | Talend,
