Using:

Jboss AS 7.1.1

Java 1.6

Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production

ojdbc6.jar Implementation-Version: 11.2.0.2.0

quartz-2.1.6

What could be the problem?

Answer 1

Removing ojdbc6.jar from the classpath and adding JBoss module (ojdbc6 module) as dependency solved the issue.

Answer 2

We found elegant solution to this problem. it worked. We need to add oracle module in global-modules as below.

    <subsystem xmlns="urn:jboss:domain:ee:1.1">
        <global-modules>
            <module name="com.oracle" slot="main"/>
        </global-modules>

        <spec-descriptor-property-replacement>false</spec-descriptor-property-replacement>
        <jboss-descriptor-property-replacement>true</jboss-descriptor-property-replacement>
    </subsystem>

Answer 3

Successfully solved the same issue for JBoss EAP 6. The main idea is the same - remove jar from war (if it was there) and let the app server to provide it. The details are below.

1) Added WEB-INF/jboss-deployment-structure.xml:

<jboss-deployment-structure>
<deployment>
    <dependencies>
        <module name="com.oracle" />
    </dependencies>
</deployment>
</jboss-deployment-structure>

2) Defined jboss\eap640\modules\system\layers\base\com\oracle\main\module.xml

<module xmlns="urn:jboss:module:1.1" name="com.oracle">
  <resources>
    <resource-root path="ojdbc7.jar"/>
  </resources>
  <dependencies>
    ...
  </dependencies>
</module>

3) Put ojdbc7.jar into jboss\eap640\modules\system\layers\base\com\oracle\main.
