Using XML with Legacy Business Applications

The Java implementation of the design is composed of the source files listed below. We're not breaking any new ground in any of this code, so I won't add anything to the detailed design discussion presented in the previous sections.

  • FlatToXML.java : the main routine for the Java application with flat files as source

  • FlatSourceConverter.java (in package net.babelblaster.convert) : the class that drives conversion from flat files to XML

  • FlatRecordReader.java (in package net.babelblaster.record) : the class that handles reading flat file records and converting to XML

  • XMLToFlat.java : the main routine for the Java application with flat files as target

  • FlatTargetConverter.java (in package net.babelblaster.convert) : the class that drives conversion from XML to flat files

  • FlatRecordWriter.java (in package net.babelblaster.record) : the class that handles reading XML and building and writing flat file records

  • DataCellN.java (in package net.babelblaster. cell ) : the class that handles legacy format number fields with implied decimal places

  • DataCellDateYYYYMMDD.java (in package net.babelblaster.cell) : the class that handles date fields in YYYYMMDD representation in legacy formats
