Type in the Java code you want to execute according to the task you need to perform. For further information about Java functions syntax specific to Talend , see Talend Studio Help Contents (Help > Developer Guide > API Reference).

This component offers the advantage of the dynamic schema feature. This allows you to retrieve unknown columns from source files or to copy batches of columns from a source without mapping each column individually. For further information about dynamic schemas, see Talend Studio User Guide. Information noteNote: If your custom Java code references
org.talend.transform.runtime.api.ExecutionStatus, change it
to
org.talend.transform.runtime.common.MapExecutionStatus.
