ClassNotFoundException with MANIFEST.MF dependencies specified

poesys Feb 19, 2013 8:09 PM

I am adding the Oracle JDBC and connection pooling jar files ojdbc6.jar and ucp.jar to the AS7 modules system. This works fine for JNDI access, but I also use a third-party library that accesses JDBC directly for lazy-loading. When it does, I get the following error:

15:44:05,941 WARN [org.jboss.modules] (http--127.0.0.1-8080-5) Failed to define class oracle.ucp.jdbc.PoolDataSource in Module "com.oracle.ucp:main" from local module loader @625dcec6 (roots: /opt/jboss-as-7.1.1.Final/modules): java.lang.LinkageError: Failed to link oracle/ucp/jdbc/PoolDataSource (Module "com.oracle.ucp:main" from local module loader @625dcec6 (roots: /opt/jboss-as-7.1.1.Final/modules))

The MANIFEST.MF file has the dependency with a line return at the end:

Manifest-Version: 1.0
Dependencies: com.oracle.ojdbc6,com.oracle.ucp

and the manifest loads correctly as far as I can tell. I've tried the jboss-deployment-structure.xml version of dependency specs as well, no difference, same error.

If I place the files directly into the WEB-INF/lib and remove the manifest/xml dependencies, everything works fine.

Does anyone have any suggestions as to why the web app can't load the shared jar files?

Might be a problem that the modules does not include the correct dependencies.
Could you show the modul.xml files for your modules?

Here are the XML files for ojdbc6.jar and ucp.jar. Note that the modules work fine with JNDI but don't work with standalone JDBC calls within the web app, which I don't think would be the case if the dependencies were wrong. In any case, the JDBC driver has no dependencies and the UCP file only depends on JDBC.

<?xml version="1.0" encoding="UTF-8"?>

<module xmlns="urn:jboss:module:1.0" name="com.oracle.ojdbc6">
<resources>
    <resource-root path="ojdbc6.jar"/>
</resources>
<dependencies>
    <module name="javax.api"/>
</dependencies>
</module>

<?xml version="1.0" encoding="UTF-8"?>

<module xmlns="urn:jboss:module:1.0" name="com.oracle.ucp">
<resources>
    <resource-root path="ucp.jar"/>
</resources>
<dependencies>
    <module name="com.oracle.ojdbc6"/>
</dependencies>

It can still be about dependencies...

I'd test adding the javax.api dependency to ucp first as that is what it is complaining about.

I added the line <module name="javax.api"/> to the ucp.jar XML file, and that seems to have fixed the problem. I would have thought that the javax.api line in the ojdbc6.jar XML file would have sufficed, by transitivity, but apparently not; each dependency needs to be done separately.

Thanks!
