DataMatrix per GS1
The goal is a machine-readable java.awt.Image of a valid DataMatrix via ZXing. The bundled DataMatrixWriter suffices for simple cases; for a valid GS1 code small changes to the ZXing source are needed (codeword FNC1 before each variable-length codeword).
| Info |
|---|
| title | Application Identifier |
|---|
|
Each data field starts with a 2–3-digit Application Identifier (e.g. (01)) indicating which GS1 data follows. |
Classpath parameter
To use it via Jasper, create the parameter nuclos.jasper.reports.compile.classpath.jars.byclasses with this value:
| Codeblock |
|---|
|
net.sf.jasperreports.engine.JasperReport org.nuclos.server.report.api.JRNuclosDataSource com.google.zxing.BarcodeFormat com.google.zxing.WriterException com.google.zxing.client.j2se.MatrixToImageWriter com.google.zxing.common.BitMatrix com.datamatrixnuc.DataMatrixClass |
Data source (application identifier)
The AIs are composed in SQL (example):
| Codeblock |
|---|
|
'(01)'||t2.intgtin13||'(17)'||to_char(t5.dathaltbarkeitsdatum,'YYmm00')||'(10)'||t5."strchargencode"||'(240)'||t2.strartikelnummer "strnummer" |
Embedding the extension
Place the required JARs in <Nuclos>/extensions/server/, run the installer again (or copy the JARs manually to webapp/WEB-INF/lib) and restart the server. Details: Jasper extensions.
