moleculeJ This is the core of Nevitium. The database engine I started when learning Java some years ago.  This distribution on Sourceforge is not maintained.  The coding project is out of sync with the distribution by a year.  It now includes two different (transaction & atomic style) distributed network database engines as well as the regular local engine.  All are small and very simple to use and they all maintain the same data files.  If you want the current source, build or library email me.  If you need to store/access data from a hand held network device this may be a great choice.  Very low overhead.  No SQL.  CSV import/export and enhanced search routines.  I also have several Netbeans projects available for examples.
PDFLabels.java Java developers can shoot out Avery TM style labels (barcode too!) in minutes!  Public domain, completely free in every respect.  Requires iText.
DymoPrinter.java Print Dymo or Co Star labels easily with pure Java.  BETA  This class has not been tested as I do not have a DYMO label writer.  Should work with little modification if any.
LinePrinter.java This class simulates a line printer (dot matrix) and allows you to print text strings to a printer easily from java.  Provide the font, feed it some text and you have a printed (8.5 x 11) document.  Portrait or Landscape, you can also change the font when issuing a form feed.  Modify it for your needs or learn how to print in Java.

"don't change anything until the problem is obvious" --Sean Anderson

On July 1-2, 1991, computer-software collapses in telephone switching stations disrupted service in Washington DC, Pittsburgh, Los Angeles and San Francisco. Once again, seemingly minor maintenance problems had crippled the digital System 7. About twelve million people were affected in the crash of July 1, 1991. Said the New York Times Service: "Telephone company executives and federal regulators said they were not ruling out the possibility of sabotage by computer hackers, but most seemed to think the problems stemmed from some unknown defect in the software running the networks." Within the week, a red-faced software company, DSC Communications Corporation of Plano, Texas, owned up to glitches in the signal transfer point software that DSC had designed for Bell Atlantic and Pacific Bell. The immediate cause of the July 1 crash was a single mistyped character: one tiny typographical flaw in one single line of the software. One mistyped letter, in one single line, had deprived the nations capital of phone service. It was not particularly surprising that this tiny flaw had escaped attention: a typical System 7 station requires ten million lines of code.

The first operational launch attempt of the space shuttle, whose real-time operating software consists of about 500,000 lines of code, failed because of a synchronization problem among its flight-control computers. The software error responsible for the failure, which was itself introduced when another error was fixed two years earlier, would have revealed itself, on the average, once in 67 times.
