Hello everybody,
I try to learn ipojo to implement a simple server using Netbeans 7.4 and
Apache Karaf.
My first goal is to write a really simple server which just prints a
message when it's activated or deactivated. No tutorial which I found
gave enough information to perform such a simple task.
Here's my code:
The server interface:
package de.hermannmatthes.workbench.server;
public interface Server {
public void start();
public void stop();
}
The server implementation:
package de.hermannmatthes.workbench.server;
import java.io.FileWriter;
import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.Logger;
import org.apache.felix.ipojo.annotations.Component;
import org.apache.felix.ipojo.annotations.Instantiate;
import org.apache.felix.ipojo.annotations.Invalidate;
import org.apache.felix.ipojo.annotations.Requires;
import org.apache.felix.ipojo.annotations.Validate;
import org.osgi.service.log.LogService;
@Component(immediate=true)
@Instantiate
public class ServerImpl implements Server {
@Requires(policy="static")
private LogService log;
@Override
@Validate
public void start() {
trace("Starting workbench server, log is " + log);
log.log(LogService.LOG_INFO, "Starting workbench server.");
}
@Override
@Invalidate
public void stop() {
trace("Stopping workbench server, log is " + log);
log.log(LogService.LOG_INFO, "Stopping workbench server.");
}
private void trace(final String msg) {
FileWriter w = null;
try {
w = new FileWriter("C:/temp/test.log", true);
w.write(msg + "\n");
} catch (IOException ex) {
Logger.getLogger(ServerImpl.class.getName()).log(Level.SEVERE, null, ex);
}
finally {
if (w!=null) {
try {
w.close();
} catch (IOException ex) {
Logger.getLogger(ServerImpl.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
}
}
If I install the module in karaf and resolve it, everything's fine. But
when I start it, its state changes to Active but nothing happens. In the
attachment you find my project file.
Can someone tell me whats wrong with my code?
Any hint is welcome
Hermann
