Digester crashes in run mode and succeeds with java debugger
HI
I've got application that uses digerster. There is a bean with two setters:
public void setFf(String date);
public void setFf(Date date);
Crash happens here:
org.apache.commons.beanutils.ConversionException: DateConverter does
not support default String to 'Date' conversion.

(line numbers may slightly deviate because I've added tracing printlns)
When I try to debug this, no crash happens. Is this a known issue?
Thanx.

Hi Stepan,
I guess that in debug mode, inside your IDE JVM, the invoked method is
public void setFf(String date); OTOH, when running from console, log
clearly show that JVM invokes public void setFf(Date date);
You have two options:
* drop the Date argument support (less good, IMHO);
* Rely on Date only and configure BeanUtils doing its job - the
Digester relies on BeanUtils to perform text to Java object
unmarshalling, so for Date type you have to plug the needed converter.
(which is a better/cleaner approach)
Have a look at "Data Type Conversions"[1] to understand how to convert
the extracted XML body text to Date; basically you have
to instantiate a DateConverter[2] 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
