Mark Thomas resolved DBCP-350.
------------------------------
Resolution: Not A Problem
The analysis shows that this is caused by hibernate needing to access the raw
Oracle connection but DBCP is returning wrapped objects. That makes this a
hibernate issue unless DBCP does not provide a mechanism for hibernate to
access the raw connection (which I believe it does).
I don't see anything for DBCP to fix here.
> Problem with DBCP 1.3 /jdk 6 and oracle spatial
> -----------------------------------------------
>
> Key: DBCP-350
> URL: https://issues.apache.org/jira/browse/DBCP-350
> Project: Commons Dbcp
> Issue Type: Bug
> Affects Versions: 1.3, 1.4
> Environment: CentOS 5.5 x86_64, Oracle JDK 1.6u22 32bit, Tomcat
> 5.5.31, ojdbc6.jar
> Reporter: Nils Hildebrand
> Fix For: 1.3.1, 1.4.1
>
>
> We have a GIS-application running on Tomcat 5.5. As webserver we are using
> Apache httpd 2.2 connected to tomcat via ajp (mod_proxy_ajp).
> The application worked fine with Tomcat 5.5.28 until we tried to upgrade to
> Tomcat 5.5.31.
> After the upgrade we get - in certain situations a:
> java.io.IOException: org.hibernatespatial.helper.FinderException: Couldn't get
> at the OracleSpatial Connection object from the PreparedStatement.
> After looking through the Tomcat 5.5 changelogs we stumbled across a change
> made in 5.5.30: Upgrade to DBCP 1.3.
> I can affirm now that the problem is gone when downgrading to DBCP 1.2.2.
> The same problem occurs when using DBCP 1.4.
> It seems something has changed from 1.2.2 to 1.3 that has partially broken
> Oracle-Locator operations in dbcp 1.3
> I've seen some bug-reports for dbcp 1.3.1 which point in the same direction
> (oracle-db-error lead to java error) - perhaps these are the same problems...
