Groovy casting exception

[pawel_r]

Hi

I am fetching data from Oracle database (v 9.2) into my jasprereport (v 3.6.0). When I try to put a oracle.sql.timestamp(6) field into my report I get following error:

org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'oracle.sql.TIMESTAMP@b20eb8' with class 'oracle.sql.TIMESTAMP' to class 'oracle.sql.TIMESTAMP'

(details below)

I don't quite get the reason of the error. I changed the field type to java.sql.timestamp and I removed quotation marks added by iReport. Anyone has faced similar problem?

Hi,

 

What Groovy version do you use? What Oracle driver? Have you tried change the report language to Java, just so that we see if problem is related to Groovy only?

 

Thank you,
Teodor

I am using iReport (v 3.6) and in its library directory I see groovy-all-1.5.5.jar, so I assume it is versios 1.5.5 :) Changing to java generates an error, since Java doesn't allow non explicit casting from oracle.sql.timestamp to java.sql.timestamp (and unfortuantelly I am using groovy capabilities in many other places - I will prepare a separate report to check taht issue) Oracle driver is ojdbc14.jar

Thank you for response
