I am trying to implement the Apache Configuration 2 in my codebase
import java.io.File;
import java.util.concurrent.TimeUnit;
import org.apache.commons.configuration2.PropertiesConfiguration;
import org.apache.commons.configuration2.builder.ConfigurationBuilderEvent;
import org.apache.commons.configuration2.builder.ReloadingFileBasedConfigurationBuilder;
import org.apache.commons.configuration2.builder.fluent.Parameters;
import org.apache.commons.configuration2.convert.DefaultListDelimiterHandler;
import org.apache.commons.configuration2.event.EventListener;
import org.apache.commons.configuration2.ex.ConfigurationException;
import org.apache.commons.configuration2.reloading.PeriodicReloadingTrigger;
import org.apache.commons.configuration2.CompositeConfiguration;
public class Test {
private static final long DELAY_MILLIS = 10 * 60 * 5;
public static void main(String[] args) {
// TODO Auto-generated method stub
CompositeConfiguration compositeConfiguration = new CompositeConfiguration();
PropertiesConfiguration props = null;
try {
props = initPropertiesConfiguration(new File("/tmp/DEV.properties"));
} catch (ConfigurationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
compositeConfiguration.addConfiguration( props );
compositeConfiguration.addEventListener(ConfigurationBuilderEvent.ANY,
new EventListener<ConfigurationBuilderEvent>()
{
#Override
public void onEvent(ConfigurationBuilderEvent event)
{
System.out.println("Event:" + event);
}
});
System.out.println(compositeConfiguration.getString("property1"));
try {
Thread.sleep(14*1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// Have a script which changes the value of property1 in DEV.properties
System.out.println(compositeConfiguration.getString("property1"));
}
protected static PropertiesConfiguration initPropertiesConfiguration(File propsFile) throws ConfigurationException {
if(propsFile.exists()) {
final ReloadingFileBasedConfigurationBuilder<PropertiesConfiguration> builder =
new ReloadingFileBasedConfigurationBuilder<PropertiesConfiguration>(PropertiesConfiguration.class)
.configure(new Parameters().fileBased()
.setFile(propsFile)
.setReloadingRefreshDelay(DELAY_MILLIS)
.setThrowExceptionOnMissing(false)
.setListDelimiterHandler(new DefaultListDelimiterHandler(';')));
final PropertiesConfiguration propsConfiguration = builder.getConfiguration();
PeriodicReloadingTrigger trigger = new PeriodicReloadingTrigger(builder.getReloadingController(),
null, 1, TimeUnit.SECONDS);
trigger.start();
return propsConfiguration;
} else {
return new PropertiesConfiguration();
}
}
}
Here is a sample code that I using to check whether the Automatic Reloading works or not. However when the underlying property file is updated, the configuration doesn't reflect it.
As per the documentation :
One important point to keep in mind when using this approach to reloading is that reloads are only functional if the builder is used as central component for accessing configuration data. The configuration instance obtained from the builder will not change automagically! So if an application fetches a configuration object from the builder at startup and then uses it throughout its life time, changes on the external configuration file become never visible. The correct approach is to keep a reference to the builder centrally and obtain the configuration from there every time configuration data is needed.
https://commons.apache.org/proper/commons-configuration/userguide/howto_reloading.html#Reloading_File-based_Configurations
This is different from what the old implementation was.
I was able to successfully execute your sample code by making 2 changes :
make the builder available globally and access the configuration from the builder :
System.out.println(builder.getConfiguration().getString("property1"));
add the listener to the builder :
`builder.addEventListener(ConfigurationBuilderEvent.ANY, new EventListener() {
public void onEvent(ConfigurationBuilderEvent event) {
System.out.println("Event:" + event);
}
});
Posting my sample program, where I was able to successfully demonstrate it
import java.io.File;
import java.util.concurrent.TimeUnit;
import org.apache.commons.configuration2.PropertiesConfiguration;
import org.apache.commons.configuration2.builder.ConfigurationBuilderEvent;
import org.apache.commons.configuration2.builder.ReloadingFileBasedConfigurationBuilder;
import org.apache.commons.configuration2.builder.fluent.Parameters;
import org.apache.commons.configuration2.event.EventListener;
import org.apache.commons.configuration2.reloading.PeriodicReloadingTrigger;
public class TestDynamicProps {
public static void main(String[] args) throws Exception {
Parameters params = new Parameters();
ReloadingFileBasedConfigurationBuilder<PropertiesConfiguration> builder =
new ReloadingFileBasedConfigurationBuilder<PropertiesConfiguration>(PropertiesConfiguration.class)
.configure(params.fileBased()
.setFile(new File("src/main/resources/override.properties")));
PeriodicReloadingTrigger trigger = new PeriodicReloadingTrigger(builder.getReloadingController(),
null, 1, TimeUnit.SECONDS);
trigger.start();
builder.addEventListener(ConfigurationBuilderEvent.ANY, new EventListener<ConfigurationBuilderEvent>() {
public void onEvent(ConfigurationBuilderEvent event) {
System.out.println("Event:" + event);
}
});
while (true) {
Thread.sleep(1000);
System.out.println(builder.getConfiguration().getString("property1"));
}
}
}
The problem with your implementation is, that the reloading is done on the ReloadingFileBasedConfigurationBuilder Object and is not being returned to the PropertiesConfiguration Object.

I want to close browsers after completion of all test. Problem is I am not able to close the browser since the object created ThreadLocal driver does not recognize the driver after completion of test value returning is null.

Thanks in Advance.
private static ThreadLocal<dummy> driver is added at the class level. What is happening is that you have already declared the variable at class level. i.e. memory is already allocated to it. Multiple threads are just setting and resetting the values of the same variable.
What you need to do is create a factory that will return an instance of Driver based on a parameter you pass to it.Logic can be anything but taking a general use case example the factory will create a new object and return only if an existing object doesn't exist. Declare and initialise the driver (from factory) in your #Test Methods
Sample code for the factory would be something like
static RemoteWebDriver firefoxDriver;
static RemoteWebDriver someOtherDriver;
static synchronized RemoteWebDriver getDriver(String browser, String browserVersion, String platform, String platformVersion)
{
if (browser == 'firefox')
{
if (firefoxDriver == null)
{
DesiredCapabilities cloudCaps = new DesiredCapabilities();
cloudCaps.setCapability("browser", browser);
cloudCaps.setCapability("browser_version", browserVersion);
cloudCaps.setCapability("os", platform);
cloudCaps.setCapability("os_version", platformVersion);
cloudCaps.setCapability("browserstack.debug", "true");
cloudCaps.setCapability("browserstack.local", "true");
firefoxDriver = new RemoteWebDriver(new URL(URL),cloudCaps);
}
}
else
{
if (someOtherDriver == null)
{
DesiredCapabilities cloudCaps = new DesiredCapabilities();
cloudCaps.setCapability("browser", browser);
cloudCaps.setCapability("browser_version", browserVersion);
cloudCaps.setCapability("os", platform);
cloudCaps.setCapability("os_version", platformVersion);
cloudCaps.setCapability("browserstack.debug", "true");
cloudCaps.setCapability("browserstack.local", "true");
someOtherDriver = new RemoteWebDriver(new URL(URL),cloudCaps);
}
return someOtherDriver;
}
You have a concurrency issue: multiple threads can create a ThreadLocal instance because dummy == null can evaluate to true on more than one thread when run in parallel. As such, some threads can execute driver.set(new dummy()); but then another thread replaces driver with a new ThreadLocal instance.
In my experience it is simpler and less error prone to always use ThreadLocal as a static final to ensure that multiple objects can access it (static) and that it is only defined once (final).
You can see my answers to the following Stack Overflow questions for related details and code samples:
How to avoid empty extra browser opens when running parallel tests with TestNG
Session not found exception with Selenium Web driver parallel execution of Data Provider test case
This is happening because you are creating the driver instance in beforeMethod function so it's scope ends after the function ends.
So when your afterMethod start it's getting null because webdriver instance already destroy as beforeMethod function is already completed.

What is the default scope of a method in Java?
I thought this would be a simple question but I am having trouble finding an answer. I have a single ImageView object associated with a JavaFX Scene object and I want to load large images in from disk and display them in sequence one after another using the ImageView. I have been trying to find a good way to repeatedly check the Image object and when it is done loading in the background set it to the ImageView and then start loading a new Image object. The code I have come up with (below) works sometimes and sometimes it doesn't. I am pretty sure I am running into issues with JavaFX and threads. It loads the first image sometimes and stops. The variable "processing" is a boolean instance variable in the class.
What is the proper way to load an image in JavaFX in the background and set it to the ImageView after it is done loading?
public void start(Stage primaryStage) {
...
ImageView view = new ImageView();
((Group)scene.getRoot()).getChildren().add(view);
...
Thread th = new Thread(new Thread() {
public void run() {
while(true) {
if (!processing) {
processing = true;
String filename = files[count].toURI().toString();
Image image = new Image(filename,true);
image.progressProperty().addListener(new ChangeListener<Number>() {
#Override public void changed(ObservableValue<? extends Number> observable, Number oldValue, Number progress) {
if ((Double) progress == 1.0) {
if (! image.isError()) {
view.setImage(image);
}
count++;
if (count == files.length) {
count = 0;
}
processing = false;
}
}
});
}
}
}
});
}
I actually think there's probably a better general approach to satisfying whatever your application's requirements are than the approach you are trying to use, but here is my best answer at implementing the approach you describe.
Create a bounded BlockingQueue to hold the images as you load them. The size of the queue may need some tuning: too small and you won't have any "buffer" (so you won't be able to take advantage of any that are faster to load than the average), too large and you might consume too much memory. The BlockingQueue allows you to access it safely from multiple threads.
Create a thread that simply loops and loads each image synchronously, i.e. that thread blocks while each image loads, and deposits them in the BlockingQueue.
Since you want to try to display images up to once per FX frame (i.e. 60fps), use an AnimationTimer. This has a handle method that is invoked on each frame render, on the FX Application Thread, so you can implement it just to poll() the BlockingQueue, and if an image was available, set it in the ImageView.
Here's an SSCCE. I also indicated how to do this where you display each image for a fixed amount of time, as I think that's a more common use case and might help others looking for similar functionality.

I am trying to connect my Desktop to the PHILIPS Hue light server using java.
When the code runs, it will flow into the Controller.java. When that happens, the FindBridges method in Controller.java runs. This is where the error occurs. In debugging, it displays a NullPointerException in thread "AWT-Event-Queue-0".
I presume that the server/lightbulb cannot be found at all, even though it is turned on and my android application can connect to it.
The error is stated below:

Did you ever solve this? In future it is probably best to post hue Java SDK issues on the GitHub site. https://github.com/PhilipsHue/PhilipsHueSDK-Java-MultiPlatform-Android/issues
I would have seen this sooner on here (I wrote this code btw so am possibly the culprit).
I do remember seeing a similar issue before, am pretty sure it was related to Macs and the JDK Compiler level used (I possibly used an incompatible Swing component on Mac and JDK 1.6). Can you let me know your OS and JDK Compiler level and I will check this further?
I have a requirement like communicating two vaadin portlets in Liferay.
One portlet is with vaadin tree view showing reports name(webi reports).While clicking on the tree,I have to open the corresponding report in another portlet.
Could anyone please suggest your ideas and share the details in meeting this requirement.
Thaks in advance.
One straightforward solution would be the Vaadin IPC add-on. See details and examples at: http://vaadin.com/addon/vaadin-ipc-for-liferay
Note, that this requires to use 6.x version of Vaadin.
I have instlled vaadin control panel for liferay and installed vaadin liferay ipc in tomcat.
The below codes of two portlets sender and receiver .But I cannt able to receive.PLease help in solving this
**sender :**

public void init() {
Window window = new Window();
setMainWindow(window);
Label label = new Label("Hello Senderipc!");
window.addComponent(label);
LiferayIPC ipc = new LiferayIPC();
ipc.sendEvent("eventid1", "This is sender 1");
window.addComponent(ipc);
}
}
**receiver**

});
window.addComponent(liferayipc);

I have an Xpage page with a single Notes document datasource.
After saving a document I want to (conditionally) trigger an agent. The agent takes some time to process and we don't want the user to have to wait for the result, so it should be executed asynchronously.
I've managed to get it working from client side JS by using an XHR to the agent URL, but I would like to do it server side so I can control the "Next page" better. When using .run() or .runonserver() the client waits till the agent completes.
Any idea how I could trigger an agent (from SSJS) on PostSaveDocument without the client waiting for the result?
Try to look at Thread and Jobs application on OpenNTF.org. There are nice demos of running task in background, check it here
As Martin suggested I used the JobScheduler example on OpenNtf and modified it to suit my needs. Resulting code can be found below. Any comments or improvements are welcome.

You could use a session bean (so it won't get destroyed) that kicks off an Java thread. Or you could issue in code a server console command. Or you implement a DOTS listener.
This may/may not be an option depending on your application requirements but I am having good success calling function in the onClientLoad event which essentially kicks off the process after the XPage has fully loaded.
