schedule a message driven bean to access a queue during certain times? - java

1) Can you schedule a message driven bean to access a queue only at certain times?
For example, user has two contact options - between 9am-5pm and 5pm-10pm. I'd like to have two MDB one that is only active from 9am-5pm and the other at 3pm-10pm.
Both queues have messages sent to them throughout the day but I'd only like to process them at the specific times.
Ideally #Schedule would work but unfortunately it doesn't.
Using Glassfish 3.1.2 and ActiveMQ 5.5.1 but I'm pretty sure it's not an implementation specific question.
Edit 1
Code
#MessageDriven(
activationConfig = {
#ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
#ActivationConfigProperty(propertyName = "destination", propertyValue = "jms/queue/amqmsg")
})
public class ExampleMessageBean implements MessageListener {
#Schedule(second="*", minute="*", hour="9-17", persistent = false)
public void onMessage(Message message) {
try {
System.out.println("We've received a message: " + message.getJMSMessageID());
System.out.println("\n\n Message\n\n" + message);
} catch (JMSException e) {
e.printStackTrace();
}
}
}
Getting error on deployment. I don't think it's possible for #Schedule to be used in this way. Can anyone confirm?

Schedule doesnt like being called on your method which has the message param. How would it know this argument.
Just add the items to a queue and process seperately.
#MessageDriven(
activationConfig = {
#ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
#ActivationConfigProperty(propertyName = "destination", propertyValue = "jms/queue/amqmsg")
})
public class ExampleMessageBean implements MessageListener {
private BlockingQueue<Message> queue = new ArrayBlockingQueue<Message>() ;
#Schedule(second="*", minute="*", hour="9-17", persistent = false)
public void process()
{
//process queue here.
}
public void onMessage(Message message) {
try {
System.out.println("We've received a message: " + message.getJMSMessageID());
queue.add(message);
System.out.println("\n\n Message\n\n" + message);
} catch (JMSException e) {
e.printStackTrace();
}
}

However, when I remove the message driven bean from my ejb. My ejb can run smoothly.
Any ideas on how to resolve this issue?

I guess your EJB module uses the EJBContainer. A word of caution is that the EJBContainer only supports EJB lite which does not include remote EJBs nor MDBs. Refer to this link for details
EJBContainer is mainly for testing in JUnit, it is not meant for production code.
You get the exception
Caused by: java.lang.IllegalArgumentException: MQJMSRA_AS4001:
setSubscriptionDurability:Invalid subscriptionDurability=durable
because the subscriptionDurability property value is case sensitive and you specified it as lowercase, i.e. "durable" instead of the correct value of Durable (i.e. with first letter capitalized)
I've had the same problem and this was the cause.
This property enables you to configure the durability of the topic
subscriber. Durable subscribers can survive any disconnection from the
JMS server.
The valid values are Durable and NonDurable.
The problem can be reproduced with the following MDB (Message Driven Bean):
#JMSDestinationDefinition(name = "BookingTopic", interfaceName = "javax.jms.Topic",
resourceAdapter = "jmsra", destinationName = "BookingTopic") #MessageDriven(activationConfig = {
#ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Topic"),
#ActivationConfigProperty(propertyName = "destinationLookup", propertyValue = "BookingTopic"),
#ActivationConfigProperty(propertyName = "subscriptionDurability", propertyValue = "durable"),
#ActivationConfigProperty(propertyName = "clientId", propertyValue = "BookingTopic"),
#ActivationConfigProperty(propertyName = "subscriptionName", propertyValue = "BookingTopic") }) public class ReservationNotifier implements MessageListener {
private static final Logger loggger = Logger.getLogger(ReservationNotifier.class.getSimpleName());
public ReservationNotifier() {
}
#Override
public void onMessage(Message message) {
try {
Booking booking = (Booking) ((ObjectMessage) message).getObject();
loggger.log(Level.INFO, "Sending e-mail containing reservation information to {0}", booking.getCustomer().getEmail());
} catch (JMSException ex) {
loggger.log(Level.SEVERE, "Error reading booking from topic");
}
}
}

Can not deploy Java Web Service to Glassfish

I am trying to deploy a simple web service to Glassfish. Here is the web service class:
import com.dv.testrunner.extended.Task;
import com.medallion.etl.exception.StepExecutionException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;
/**
*
* #author dvargo
*/
#WebService(serviceName = "Execute")
public class Execute
{
/**
* Web service operation
*/
#WebMethod(operationName = "executeTask")
public boolean executeTask(#WebParam(name = "task") Task task)
{
boolean setUp = task.setUp();
boolean execute;
try
{
execute = task.execute();
}
catch (StepExecutionException ex)
{
Logger.getLogger(Execute.class.getName()).log(Level.SEVERE, null, ex);
return false;
}
return setUp && execute;
}
}
Task is a simple interface. Here is the interface:
package com.dv.testrunner.extended;
import com.medallion.etl.exception.StepExecutionException;
/**
*
* #author dvargo
*/
public interface Task
{
public boolean execute() throws StepExecutionException;
public boolean setUp();
}
When I try to deploy my web service via Netbeans, I get the following error:

Does anyone have any ideas on what is happening and how I may fix it? Is it that I can not use Task as a parameter?
JAX-WS does not allow interfaces as method parameters. Try replacing Task with a class.
Not only JAX-WS does not allow interfaces, it even makes no sense in your case. How would you specify what the task is supposed to do? You need a concrete class as a parameter, and the class needs to be annotated with #XmlRootElement. If you want your endpoint to support different tasks, you will need more operations with different names to achieve that.

Returning JSONP for a Suspended Atmosphere request

I have a servlet that has a suspending method and a broadcasting one:
#GET
#Path("/notification")
#Produces( { "application/x-javascript", MediaType.APPLICATION_JSON })
#Suspend
public JSONWithPadding getNextNotification(
#QueryParam("callback") #DefaultValue("callback") String callback) {
Random random = new Random();
Notification n = new Notification();
n.setMessage("Message is " + Long.toHexString(random.nextLong()));
n.setMessage("S-" + Long.toHexString(random.nextLong()));
return new JSONWithPadding(n, callback);
}
I invoke this from a browser and see the following nice output in my browser:
<!-- ---------------------------------------------------------------- http://github.com/Atmosphere ------------------------------------------------------------------------ -->
<!-- Welcome to the Atmosphere Framework.....
<!-- --------------------------------------------------------------------------------------------------------------------------------------------------------------------- -->
<!-- EOD -->callback({"message":"S-c897404ad5703dcc","sender":null}
So my object is nicely serialized to JSONP.
Now I call my broadcaster method:
#Context Broadcaster bc;
#Broadcast({JsonpFilter.class})
#GET
#Path("/broadcast5")
public Broadcastable broadcast5() {
Random random = new Random();
Notification n = new Notification();
n.setMessage("Message is " + Long.toHexString(random.nextLong()));
n.setMessage("S-" + Long.toHexString(random.nextLong()));
return new Broadcastable(new JSONWithPadding(n, "callback111"), bc);
}
On the server side I get the following exception and nothing is broadcasted:

How could I make my broadcaster work? Do I need to return JSONWithPadding object or only the POJO?
You get an AbstractMethodError. Do you have atmosphere-commons on your classpath?

Injecting a named String using CDI

I want to have a configuration parameter injected this way:
public class MyManagedBean {
#Inject
public MyManagedBean(#Named("user") String user){
....
}
}
So I tried to implement a producer method this way:
#ApplicationScoped
public class MyConfiguration {
private Properties loadProperties() {
Properties properties = new Properties();
try {
properties.load(getClass().getResourceAsStream(
"user.properties"));
} catch (IOException e) {
throw new RuntimeException();
}
return properties;
}
#Produces
#Named("user")
String getUser() {
return loadProperties().getProperty("user");
}
}
I have other bean defined this way:
public class OtherManagedBean {
#Inject
public OtherManagedBean(MyManagedBean myManagedBean){
....
}
}
However, I'm having this exception when I try to deploy it:
INFO: WEB0671: Loading application [example-ear#example-war.war] at [example]

Any idea?
Thanks.
It looks like you need a default (no-arg) constructor for your MyManagedBean to make it proxyable. I am not really sure about why it is needed, since MyManagedBean is a #Dependent bean and so is not proxied AFAIK; I do not know even why a proxyable bean needs a default constructor, to be honest This seems to be an implementation detail or a little point from CDI specification that was ignored. Anyway, I bet it can make a good new question :)
EDIT: I discovered why a proxyable bean needs a default construction. It is no mistery, actually: since the proxy of a bean is a subclass of the same bean, the proxy needs to call a super() constructor in its own construction. If it has no non-private default constructor, it does not know which constructor to call. One can even imagine a scenario where the injected constructor is called to create the proxy, but I do not know which kind of complexity it can add to a CDI implementation; it may not be so easy to do...

java/jsf strange error: WARNING: StandardWrapperValve PWC1406: Servlet.service() ... threw exception java.lang.NullPointerException

I have simple jsf app with servlet for dynamic images and filter setting utf8 encoding. From time to time (1/10 requests) I get very strange error:

Here's my servlet and filter, I marked with asterisks lines referencing to stacktrace:
#WebServlet(urlPatterns = "/images/*")
public class ImageServlet extends HttpServlet {
#Inject
private FileService fileService;
#Override
public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException {
byte[] img = fileService.getImage(request.getPathInfo());
if (img != null) {
response.setContentType("image/png");
response.addHeader("Content-Length", String.valueOf(img.length));
ServletOutputStream os = response.getOutputStream();
os.write(img);
* os.flush();
os.close();
} else {
response.sendRedirect(request.getContextPath() + "/error");
}
}
}
#WebFilter(urlPatterns = "/*")
public class CharacterEncodingFilter implements Filter {
#Override
public void init(FilterConfig filterConfig) {
}
#Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");
* chain.doFilter(request, response);
}
#Override
public void destroy() {
}
}
I have completely no idea what's going on... I'm using Glassfish 3.1.1 web profile with jdk7
Flushing is already implicitly done when you close the stream. Closing is already implicitly done by the container itself. You actually do not need to do it yourself. However, most servlet developers do it to have early feedback for the case they overlooked that something else further in the request-response chain is writing to the output stream, e.g. a buggy filter or response wrapper or something. This would then result in an IOException on every call because the stream is closed.
In any case, you have 2 options to treat the flush() and close():
Put them in a try-catch wherein you ignore the exception.
Remove those 2 lines. The container does that for you anyway. It will also just ignore the exception.
This exception is just a sign that the client aborted the connection. E.g. pressed [Esc] or closed the window/tab or navigated away to a different page while the image is still streaming.
See also:
Should I close the servlet outputstream?
at com.sun.grizzly.util.OutputWriter.notifyRemotelyClosed()
Somehow this looks to me as if the connection you are flushing the stream of has intermediately been closed by the remote peer (a web browser?).
Can you try response.flushBuffer() instead. Does this also throw the exception?
