JB,
Keep in mind the web application, .war not .wab, correctly retrieved a
Bluetooth define service. It is the @Component defined service that was not
found.
Is there some additional information I can provide? Below are the methods used
to retrieve services via JNDI, I can add additional logging if needed.
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NameNotFoundException;
import javax.naming.NamingException;
protected <T> T getServiceViaJndi(Context ctx,
Class<T> serviceInterfaceClass) {
T service = null;
String serviceInterface = serviceInterfaceClass.getCanonicalName();
try {
service = (T) ctx.lookup("osgi:service/" + serviceInterface);
} catch (NameNotFoundException e) {
getLogger().warn("Not Found Service " + serviceInterface, e);
} catch (NamingException e) {
getLogger().warn("Exception Loading Service " +
serviceInterface, e);
}
getLogger().info("Loaded Service {} = {}", serviceInterface, service);
return service;
}
protected <T> T getServiceViaJndi(Class<T> serviceInterfaceClass) {
try {
Context ctx = new InitialContext();
return getServiceViaJndi(ctx, serviceInterfaceClass);
} catch (NamingException e) {
getLogger().error("Getting " + serviceInterfaceClass.getName(),
e);
return null;
}
}
