How to use Derby Client in Felix?

Question

I want to run Derby Client from within an OSGi bundle. The bundle gets built by Maven so I added a dependency to org.apache.derby:derbyclient. At runtime I get the following exception: java.sql.SQLException: No suitable driver found for jdbc:derby://localhost:1527/testdb.

Interestingly the whole thing works when I use the embedded driver and a dependency to org.apache.derby.derby. I just don't see the difference between those two.

What am I doing wrong and how can I fix it?

Some tidbits:

1. After some advice I found on the Internet I set the following OSGi header: DynamicImport-Package: *. This fixed problems with the embedded driver but the client still fails.
2. The version of Derby I use is 10.7.1.1 which should be OSGi enabled (at least it has OSGi headers).

Answer 1

Okay, although not even half an hour passed since I asked the question I found a solution. I don't know how clean it is but it seems to get the job done:

ClassLoader ctxtCl = Thread.currentThread().getContextClassLoader();
try {
    Thread.currentThread().setContextClassLoader(getClass().getClassLoader());

    try {
        Class.forName("org.apache.derby.jdbc.ClientDriver");
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }

    dbConnection = DriverManager.getConnection("jdbc:derby://localhost:1527/testdb");
} catch (SQLException e) {
    /* log, etc. */
} finally {
    Thread.currentThread().setContextClassLoader(ctxtCl);
}
