Thread Context Class Loader: Thread.currentThread.getClassLoader() /
setClassLoader(). Like this, if you have the correct Import-Package, you
can "gather" the classloaders.
Anyway, even for a demo, you can do:
feature:install jdbc
jdbc:create to create a datasource
and just use the datasource via the OSGi service or the JNDI name.

What's a TCCL?

It is "wrong" but more work to manage imports and drivers especially
if you need to optionally support multiple databases. It is cleaner
to configure a data source and just look it up from your code.

I just tried Derby - got the same issue:
java.lang.ClassNotFoundException:
org.apache.derby.jdbc.EmbeddedDriver
This is what I do to initialize the DB:
Derby:
Class.forName("org.apache.derby.jdbc.EmbeddedDriver").newInstance();
dbConnection =
DriverManager.getConnection("jdbc:derby:memory:myDB;create=true;");
H2:
Class.forName("org.h2.Driver");
dbConnection =
DriverManager.getConnection("jdbc:h2:~/myDB", "", "");
Is this wrong?

Hi Richard,
I suspect more an issue in the way that you use the h2
package in your application.
Do you have h2 package in Import-Package of your application ?
How do you use the driver ? Class.forName() ?
Do you use a datasource ?

What I did:
- added H2 Database to my application. It works fine
outside of Karaf.
- installed H2 to Karaf with "install -s
mvn:com.h2database/h2/1.4.184"
I can see the H2 bundle as "Active" (H2 Database Engine).
But when I install my application bundle in Karaf, I get
this:
java.lang.__ClassNotFoundException: org.h2.Driver not found
What's the proper way to install H2 to Karaf?
