Welcome to to my proof of concept HL7 Reporter:

These Python classes provide a simple example of how Python classes can be implemented as 
standalone Jython scripts.  I've even taken it a step further and have used knowledge gathered from
zetcode.com in order to build a Jython class (HL7ORUGui.py) which uses the Java Swing GUI library to 
implement the HL7RepClass.py script.

This Python script will parse a HL7 ORU messages as input (first argument) and will produce a
tab-delimited flat file as output (2nd argument) consisting of the following HL7 v 2.3.x fields.
MSH-3, MSH-5, PV1-2, PID-3, PID-5, ORC-1, ORC-2, ORC-3, OBR-4, and OBR-7.

I've added new class (ExampleFileFilter) for for compatibility with Java 1.4.x-1.5.x versions.  
If you have Java 1.6.x and above, you can use the existing "FileNameExtensionFilter" class.  
The source code for this class = http://bit.ly/MWL1x3 from google code.  I've included the source (.java)
and the compiled class (compiled to Java 1.5) as well in the "/lib" directory
This current version includes an the OO Python class (HL7RepClass.py) which includes the methods necessary to:
Open the input file with the HL7 ORU messages as the first argument.
Parse the input file for selected singleton HL7 fields.
Output these parsed fields in a tab-delimited format to the text file specified in the 2nd parameter.
Finally, I've also included a modified version of the standalone Jython.jar named "jython_standalone.jar".
I've added some necessary Python modules (re.py, etc.) in order to allow the HL7RepClass.py script to run in 
standalone mode.  More info on how to do this can be found here:

Another more advanced option is the One-Jar method http://goo.gl/lQMre .  However, this solution 
requires Java 1.6 and higher.
This may be an issue in some enterprise environments where legacy Java apps may require workstations to use 
an older version of the JRE such as Java 1.5.x.
