RE: [Xorm-users] ClassCastException

[Seaman, S. <Slo...@pt...>]

Wes,

I tried it both ways (boolean and java.lang.Boolean) and both times I got
the same error:
java.lang.ClassCastException
	at
com.ptilabs.clinicalTrials.commons.jdo.bean.Regimen$$EnhancerByCGLIB$$8.getE
ndDateUnknown(<generated>)
	at
com.ptilabs.clinicalTrials.main.ClinicalTrialEdit.setPage3(Unknown Source)
	at com.ptilabs.clinicalTrials.main.ClinicalTrialEdit.execute(Unknown
Source)

Any help would be great...

Thanks!

Yes, try defining it as primitive boolean or object Boolean in the Java 
interface.

It's dependent on how the JDBC driver treats the BIT type when 
converting to Java objects though, so that may also get you a 
ClassCastException.

If it doesn't work you might be able to define it as
int getEndDateUnknown()

and then write a wrapper function

boolean getEndDateUnknownBoolean() {
  return (getEndDateUnknown() == 1);
}

I don't have an Oracle installation to play with to test this from here.

Let me know how it works; I can update the Oracle driver to be smarter 
about this type of mapping.
