Installing XWiki Workspaces with Oracle 10g Enterprise Edition Release 10.2.0.3.0

Error while Installing XWIki Workspaces with Oracle 10g Enterprise Edition Release 10.2.0.3.0.

I dowloaded xwiki-workspaces-web-1.0.war and installed on jboss_4.0.3SP1.
It works find with MYSQL but my DB guys can't install it on Oracle 10g.

<property name="connection.username">xwiki</property>
<property name="connection.password">xwiki</property>
