Hi,
using iPOJO's _very nice_ OSGi Configuration Admin integration I sadly seem
unable to remove any properties from a configuration to "reset" this property
back to it's default value. Comparing the following two classes---one using
iPOJO the other one directly implementing the ManagedService interface ...
@Component(managedservice = "example1")
@Instantiate
public class Example1 {
@Property
private String key;
@Updated
private void updated() {
System.out.format("example1 = %s\n", key);
}
}
@Component
@Instantiate
public class Example2 implements ManagedService {
BundleContext ctx;
public Example2(BundleContext c) {
ctx = c;
}
@Validate
public void start() {
ctx.registerService(ManagedService.class.getName(), this,
getDefaults());
}
private Hashtable getDefaults() {
Hashtable defaults = new Hashtable();
defaults.put(Constants.SERVICE_PID, "example2");
return defaults;
}
@Override
public void updated(Dictionary properties) throws ConfigurationException {
System.out.format("example2 = %s\n", properties == null ? null :
properties.get("key"));
}
}
... with the code setting the properties looking like this ...
public void set(String value) throws Exception {
setProperty("example1", value);
setProperty("example2", value);
}
public void unset() throws Exception {
setProperty("example1", null);
setProperty("example2", null);
}
private void setProperty(String srv, String value) throws IOException {
Configuration cfg = configAdmin.getConfiguration(srv, null);
Dictionary p = cfg.getProperties();
if (p == null) {
p = new Properties();
}
if (value == null) {
p.remove("key");
} else {
p.put("key", value);
}
cfg.update(p);
}
... these are the results after calling set("qsdasdasd") followed by unset():
example1 = qsdasdasd
example2 = qsdasdasd
example1 = qsdasdasd
example2 = null
Am I using iPOJO the wrong way here? Thanks!
