Oracle JDBC in OSGI
I'm trying to migrate a simple application into our OSGi framework. I've got
the typical code that does:
Class.forName("oracle.jdbc.driver.OracleDriver");
connection = DriverManager.getConnection(url, user, pass);
and i get a CNFE on the driver. I don't have an OSGi-ified ojdbc6.jar
bundle, so I tried to embed the stuff in my bundle by using the following in
my pom:
<Embed-Dependency>*;scope=compile;artifactId=ojdbc6</Embed-Dependency>
Which gets past the CNFE, but then I get the following when deploying my
bundle:
org.osgi.framework.BundleException: Unresolved constraint in bundle <my
bundle name>: Unable to reolve 275.0: missing requirement [275.0] package;
(package=com.sun.security.auth.module)
I don't want to go down the path of finding all dependencies and embedding
them. Isn't there an OSGi-ified bundle for ojdbc6.jar around? There must
be others who are using JDBC from within OSGi, right?
Thanks,
Larry

I use the jdbc driver from SpringSource and it works fine connecting to
Oracle.
Here's the link:

Just as a note. Supporting JDBC in OSGi has been standardized in the
OSGi 4.2 Enterprise Release (chapter 125) [1].
So if you get a JDBC driver that supports that specification you can
obtain your JDBC drivers through the OSGi service registry without any
classloader tricks.
Best regards,
David

RE: Oracle JDBC in OSGI

If you must use the JDBC driver directly then the issue is with the classloader as the DriverManager is trying to load it 'behind the scenes'. Read my blog article on how to work around this:
http://joelschuster.blogspot.com/
However, I highly recommend using JPA via Eclipselink instead which works great with OSGi.
For the Oracle Driver... we OSGi-ified it using bnd. The turns the ojdbc6.jar into a OSGi bundle which then is used by EclipseLink.

Larry,
A number of us have slogged through getting Oracle and JDBC to work inside of Felix. To expand the number of answers you can get as you work through this process, I invite you to check out the Karaf user-group also. http://karaf.922171.n3.nabble.com/Karaf-User-f930749.html
