Hi Neil,
apologize for the late reply - the Digester relies on BeanUtils to
perform text to Java object unmarshalling, so for your enumeration(s)
type you have to plug the needed converter.
Have a look at Data Type Conversions[1] to understand how to convert
the extracted XML body text to OneDBarcodeFormat; basically you have
to implement the Converter[2] interface and register it via the
ConvertUtils.html#register()[3] method.
The Digester will do the rest.
HTH and don't hesitate on writing back to the ML if needed!
All the best,
-Simo

Hello,
I have a class which holds a set of enums; I'm writing out to the xml
file the name of the enum and I want to read it back in with Digester.
However I'm having a hard time working out how to do that - has anyone
managed to read in the enums. I'm currently trying:
Digester digester = new Digester();
digester.addObjectCreate(barcodeScanner, BarcodeScannerModel.class);
digester.addSetProperties(barcodeScanner);
digester.addCallMethod(barcodeScanner/formats/OneDBarcodeFormat,
addPossibleOneDBarcodeFormat, 1);
digester.addCallParam(barcodeScanner/formats/OneDBarcodeFormat, 0,
format);
This however returns the error message of :
java.io.IOException: org.xml.sax.SAXParseException; lineNumber: 4;
columnNumber: 39; Error at line 4 char 39: No such accessible method:
addPossibleOneDBarcodeFormat() on object:
com.ziath.datapaq.application.BarcodeScannerModel
at
com.ziath.datapaq.application.ConfigureBarcodeScannerPanel$ConfigureFileReader.load(ConfigureBarcodeScannerPanel.java:443)
The method is question is:
public void addPossibleOneDBarcodeFormat(OneDBarcodeFormat format){
this.formats.add(format);
}
The method is there so I guess it is just the parameter that is the
problem in that Digester is trying to pass a String whereas it needs an
enum. So, if anyone can help that would be greatly appreciated.
Thanks.
Cheers,
Neil
