In extending a DataRecordTransform class , how may I pass in parameters - for example I would like to pass in the keyfield and input file to a LookupTable transform.

May I add attributes to a NODE - then how do I access them?

thanks

  Hello,
  you can access node parameters in init method of your DataRecordTransform class, eg.:

  	String my_value;
  
  	public boolean init(Properties parameters,
  			DataRecordMetadata[] sourceRecordsMetadata,
  			DataRecordMetadata[] targetRecordsMetadata)
  			throws ComponentNotReadyException {
  		my_value = parameters.getProperty("my_property");
  		return super.init(parameters, sourceRecordsMetadata, targetRecordsMetadata);
  	}
  

  
  The property must be defined in your node:
  

  <Node id="REFORMAT0" transformURL="${TRANS_DIR}/test.java" type="REFORMAT" my_property="my_value">
