Symptoms

There is an issue when trying to use different version of oracle's JDBC driver.

The application is deployed using the option documented in:
Chapter 3 Utilizing the OC4J Class Loading Framework
Oracle® Containers for J2EE Developer's Guide 10g (10.1.3.1.0)
"Using a Packaged JAR Instead of an Oracle Shared Library
-----------------------------------------------------------
The class loading infrastructure enables you to package an XML parser or JDBC
driver as a JAR with your application and then force the application to use
it instead of the Oracle XML parser or JDBC driver installed with OC4J,
without having to declare the JAR as a shared library within OC4J
"

This action caused the following errors :

WARNING: Code-source
C:\work\tools\oc4j\j2ee\home\applications\application\application\WEB-INF\lib\ojdbc14.jar (fromWEB-INF/lib/ directory in
C:\work\tools\oc4j\j2ee\home\applications\application\application\WEB-INF\lib) has the samefilename but is not identical to /C:/work/tools/oc4j/jdbc/lib/ojdbc14dms.jar (from<code-source> (ignore manifest Class-Path) in META-INF/boot.xml in
C:\work\tools\oc4j\j2ee\home\oc4j.jar). If it contains different versions of the same classes, it will be masked as the latter is already visible in the search path of loaderapplication.web.application:0.0.0.
