Example of using FixedLengthWriter?

[Nobody/Anonymous]

Hello!

Could anyone explain me a simple way to create a fixed lenght file? I want to query a DB and then put the results in fixed lenght file... i guess flatpack brings me FixedLenghtWriter.

thanks a lot!
Mario.

here is a trivial extract based on the PEOPLE xml mapping

FixedWriterFactory factory = new FixedWriterFactory(mapping));
Writer writer = factory.createWriter(new FileWriter(newFile));
writer.addRecordEntry("LASTNAME", "DOE");
writer.addRecordEntry("ADDRESS", "1234 CIRCLE CT");
writer.addRecordEntry("STATE", "OH");
writer.addRecordEntry("ZIP", "44035");
writer.addRecordEntry("FIRSTNAME", "JOHN");
writer.addRecordEntry("CITY", "ELYRIA");
writer.nextRecord();
writer.flush();

Hello,
Following this trivial example… Do you know how can I get a Map from the PEOPLE xml mapping? This map will be used to create FixedWriterFactory factory = new FixedWriterFactory(mapping));

I'm think that the following is an aproach… but i'm not sure about the second argument of the FixedLengthParser constructor:

{
       FileReader fr = null;
       final File xmlFile = new File(mapping);
       fr = new FileReader(xmlFile);       
       FixedLengthParser flp = new FixedLengthParser(fr, new FileReader(data));
       Map<String,String> mp = MapParser.parse(fr,flp);
       System.out.println(mp.toString());
}
