This following scenario creates a six-component Job that shows how to handle error conditions using the tHMap component.
When tHMap executes a Talend Data Mapper map, an ExecutionStatus object is always returned. A pointer to this object is stored in the globalMap as EXECUTION_STATUS. In addition, the Overall Severity numeric value (the constants are defined in ExecutionStatus) is also stored in the globalMap as EXECUTION_SEVERITY. Finally, a parameter called Execution Threshold is defined that specifies the severity on which to throw an exception, thus triggering Job-related or component-related error processing. The default value for this parameter is Fatal.
To consult the Javadoc for the ExecutionStatus object, see the Camel Runtime documentation included in the Talend Data Mapper runtime kits and the Talend Data Mapper User Guide.
