Subject iBATIS no longer allows me to set java.sql.Timestamp property
Date Fri, 08 Feb 2008 16:55:09 GMT

I had suffered a hard drive meltdown a couple of weeks ago and had to restore
a project I am working on which involves loading objects from an Oracle
database using iBATIS.

Now I finally got the database and the application back up and running (the
database I was using to develop on was also a local instance) but when I run
my project iBATIS is complaining about setting the Timestamp properties on
my result class. 

--- Cause: java.lang.RuntimeException: Error setting property
'setActionDate' of 'com.pbg.roadnet.bo.WorkerAction@d8ca48'.  Cause:
java.lang.IllegalArgumentException: argument type mismatch; nested exception
is com.ibatis.common.jdbc.exception.NestedSQLException:   
--- The error occurred in com/pbg/roadnet/dao/sqlmap/WorkerAction.xml.  
--- The error occurred while applying a result map.  
--- Check the selectActionsWithinRange-AutoResultMap.  
--- The error happened while setting a property on the result object.  

the "ActionDate" property on my java object- which was restored from my old
project and is 100% identical to when it ran fine before- is a
java.sql.Timestamp field.

So what could suddenly cause this to fail?

I thought of two possibilities: one is that the driver I am using now is not
the same (unfortunately I did not backup the driver I was using before so I
just downloaded the latest Oracle 10g driver - ojdbc14.jar). I could maybe
start trying some older drivers if you think this is the most likely cause.

the second is that maybe I did not use the right column type on the database
tables. See, while the database version itself is exactly the same (Oracle
10g Express Edition) the tables had to be rebuilt not from scripts matching
my old schema but by reverse engineering them based on my sql map files
(basically looked at what columns I was selected, their types, and created
tables to match). So the bottom line with this is, I cant remember if I used
DATE or TIMESTAMP as the Oracle column type. I am very sure though, that I
actually used DATE, which is what I have now. But for the hell of it I tried
TIMESTAMP and still iBATIS is spitting that error at me.

Do you have any ideas what could be causing this sudden conflict?
