Hello,
I cleaned up the sources a bit and pasted them below. The code for the
master bundle is not very interesting (it shows a gui with a fileopen
button), apart from the method which loads the bundles and the method
which loads felix. Both are at the bottom of the post.
Hopefully somebody can help us.
Greetings,
Stefan
Activator.java for dynamically loaded bundle:
package nl.prifes.printer.log;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
public class Activator implements BundleActivator{
private BundleContext m_context = null;
public void start(BundleContext context) throws Exception {
System.out.println("Loading log bundle");
m_context = context;
final ClassLoader cl = context.getClass().getClassLoader();
System.out.println(cl);
Thread thread = new Thread() {
@Override
public void run() {
System.out.println("pre" +
Thread.currentThread().getContextClassLoader());
Thread.currentThread().setContextClassLoader(cl);
PrifesPrinterService serv = new PrifesPrinterService();
System.out.println("cla" +
Thread.currentThread().getContextClassLoader());
PrifesPrinter pp = serv.getPrifesPrinterPort();
System.out.println("sendpre");
System.out.println(pp.sendData(1, 1, "Test"));
}
};
thread.start();
}
public void stop(BundleContext context) throws Exception {
System.out.println("Stopping log bundle");
m_context = null;
}
}
