yesterday I wanted to implement the DidReceiveData method to my NSUrlSessionDataDelegate. I noticed that the DidReceiveData method never gets called, and while I tried to track down the error I noticed that the other methods don't get called either. I'm pretty sure that the other methods worked before, I don't know if I changed something or maybe a Xamarin.iOS update is the cause, but maybe I am wrong here and they never worked.
I can confirm this problem for the methods DidReceiveResponse, DidReceiveData, and DidCompleteWithError.
Here is the code that creates the NSUrlSession and handles the response (note: I call IIS WebMethods that answer in XML):
public async Task<string> Invoke(string sUrl)
{
session = NSUrlSession.FromConfiguration(NSUrlSessionConfiguration.DefaultSessionConfiguration,
(INSUrlSessionDelegate)new SessionDelegate((x)=> _fehlermeldung = x), // Übergebe Methode damit der SessionDelegate die Fehlermeldung weiterreichen kann
null);
request = CreateGETRequest(CreateNSUrl(sUrl));
var data = session.CreateDataTaskAsync(request, out dataTask);
dataTask.Resume();
NSUrlSessionDataTaskRequest response = null;
try
{
response = await data;
}
catch (NSErrorException ex)
{
throw new Exception(ex.Error.LocalizedDescription + ": " + _fehlermeldung);
}
var doc = new XmlDocument();
doc.LoadXml(response.Data.ToString());
XmlNode elem = doc.DocumentElement.FirstChild;
return elem.InnerText;
}
private NSUrl CreateNSUrl(string url)
{
string converted = ((NSString)url).CreateStringByAddingPercentEscapes(NSStringEncoding.UTF8);
var nsurl = NSUrl.FromString(converted);
if (nsurl == null)
throw new Exception("Fehlerhafte URL: Aus '" + url + "' konnte kein gültiges NSUrl Objekt erzeugt werden.");
return nsurl;
}
private NSMutableUrlRequest CreateGETRequest(NSUrl nsurl)
{
return new NSMutableUrlRequest(nsurl) { HttpMethod = "GET" };
}
And here is my implementation of the session delegate:
private class SessionDelegate : NSUrlSessionDataDelegate, INSUrlSessionDelegate
{
private readonly Action<string> setFehler;
public SessionDelegate(Action<string> setFehler)
{
this.setFehler = setFehler;
}
public override void DidReceiveResponse(NSUrlSession session, NSUrlSessionDataTask dataTask, NSUrlResponse response, Action<NSUrlSessionResponseDisposition> completionHandler)
{
var http_response = response as NSHttpUrlResponse;
if (http_response == null)
{
setFehler($"Keine HTTP Url Antwort erhalten: {Environment.NewLine}'{response}'");
completionHandler(NSUrlSessionResponseDisposition.Cancel);
return;
}
var status_code = (int)http_response.StatusCode;
if (status_code == 200)
{
completionHandler(NSUrlSessionResponseDisposition.Allow);
}
else
{
setFehler($"Verbindung abgewiesen, HTTP Status: { status_code}, '{ http_response.ToString()}'");
completionHandler(NSUrlSessionResponseDisposition.Cancel);
}
}
public override void DidReceiveData(NSUrlSession session, NSUrlSessionDataTask dataTask, NSData data)
{
// THIS DOES NOT GET CALLED :-(
}
public override void DidCompleteWithError(NSUrlSession session, NSUrlSessionTask task, NSError error)
{
if (error != null)
{
task.Cancel();
var ex = new NSErrorException(error);
throw (ex);
}
}
public override void DidReceiveChallenge(NSUrlSession session, NSUrlSessionTask task, NSUrlAuthenticationChallenge challenge, Action<NSUrlSessionAuthChallengeDisposition, NSUrlCredential> completionHandler)
{
[...] // This is working fine for Client Cert Authentication or Basic Authentication
}
}
The DidReceiveChallenge method does get called and is working. I cut it out for readability.
All the other methods don't get called. I would like to know what I am doing wrong. You can find the same questions from native iOS users, but I can't figure out how to implement their solutions with Xamarin.iOS.
Any help is appreciated, thanks in advance.
I am trying to implement the Apache Configuration 2 in my codebase

}
protected static PropertiesConfiguration initPropertiesConfiguration(File propsFile) throws ConfigurationException {
if(propsFile.exists()) {
final ReloadingFileBasedConfigurationBuilder<PropertiesConfiguration> builder =

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 create a java client for version proxy service present in wso2 esb. I have secured the version proxy with Username Token Authentication scenario. Now i have started creating the java client to invoke this secured proxy service and my client code is:

} catch (Exception e) {
System.out.println("invalid input, insert a integer between 1 and 15");

String str;
while ((str = console.readLine()).equals("")) {
}
return str;
} catch (Exception e) {
return null;
}
}
}
But in the above code i am struck at one line that is :
policy.addAssertion(RampartConfigBuilder.createRampartConfig(securityScenario));
Here in my rampart_core jar I am getting RampartConfigBuilder class but inside this class there is no such method called createRampartConfig. So i am unable to create Rampart configurations. What can i do to solve this issue? looking forward to your solutions. Thanks in advance

You're doing a few very odd things:
converting the byte array to a String, particularly using byte[].toString()
attempting to get an InputStream by calling Class.getResourceAsStream() with a String that has been created from the byte array.
using SMS to send an Image
Class.getResourceAsStream() is intended to take a String identifying a resource file within the MIDlet's jar file.
The correct way to do this is to get the byte[] from the BinaryMessage and use this to create an Image using Image.createImage(bytes, 0, bytes.length);
Although, as you're sending it using SMS, I'd hope it was a very small image indeed or anybody using this app will incur high costs from splitting a large image over several SMSs. Beware also that some networks limit the number of parts that an SMS can be split into.
You would be much better off researching the MMS sending functionality provided by JSR 205.
You are getting wrong the data stream, here is how you must do it:
public void create(byte[] bs)
{
try
{
im = (Image)Image.createImage(bs, 0, bs.length);
im1 = (Image)Image.createImage(im, 0, 0, i, j, Sprite.TRANS_NONE);
img = new ImageItem("yeh photo snd hui", im1, Item.LAYOUT_CENTER, "kyu nhi dikh rhi", Item.BUTTON);
frm.append(img);
}
catch (Exception e)
{
System.out.println(e);
}
}
This should work.
I need to use function with argument in a EL expression (with JSF) like this:
<h:outputText value="#{object.test(10)}" ></h:outputText>
But it doesn't work.
I read on the web that it's impossible to do this with JSF. I use facelet with JSF.
Someone knows how to do that ?
Thanks.
You could provide the method as a custom facelet function in your own taglib. The method must be static, so if you are trying to call a method on a specific bean, you would have to pass the bean, and the parameters to your static facelet function. In your case, it would be something like
<h:outputText value="#{my:doStuff(object,10)}" ></h:outputText>
and your facelet function would be
public static String doStuff( MyType o, int param )
{
return o.test( param );
}
Then, using the information in the facelets docbook you would define your function in your taglib.xml file.
It's not the prettiest solution, especially if you plan on doing this a lot, but I believe the next version of the EL (in java EE 6) will allow for using parameters in some cases.
Edit: Some info about parameterized method calls in the next version of el can be found on Ryan Lubke's Blog
I find a sad solution but it's working. I overload a map like this:
new AbstractMap<Integer, String>()
{
#Override
public Set<Entry<Integer, String>> entrySet()
{
return null;
}
#Override
public String get(final Object arg0)
{
Integer keywordDb = (Integer)arg0;
GregorianCalendar cal = new GregorianCalendar(TimeZone.getTimeZone("GMT"));
HashMap<String, String> params = new HashMap<String, String>();
params.put("keywordDb", keywordDb.toString());
params.put("month", new Integer(cal.get(Calendar.MONTH) + 1).toString());
params.put("year", new Integer(cal.get(Calendar.YEAR)).toString());
DataAnalyzeManager manager = new DataAnalyzeManager();
manager.setEm(modelPosition.getEm());
DataAnalyze data = manager.findDataByParams(params, modelPosition.getSite(), false, DataAnalyzeManager.VISITBYMONTHBYKEYWORD);
if (data != null)
return data.getDataInt().toString();
return "0";
}
};
Thereby, I can do that in my JSF:
#{homePositionController.visitByMonth[keyword.keyword.keywordDb]}
And my function is executed.
You may have to have <%# page isELIgnored ="false" %>
at the top of your pages. Read more here. The default is to ignore el expressions. What version of the JSP spec are you using with JSF? If you are using JSF 2 with JSP < 2.1 you are going to run into problems.
Also, what version of el are you using? You can't pass method params with older versions.
<dependency>
<groupId>javax.el</groupId>
<artifactId>el-api</artifactId>
<version>2.1.2-b05</version>
</dependency>
There is couple ways about doing that, you could use JBoss EL expression implementation they support method calls with parameters check out Seam, or use similar approach as #digitaljoel suggested.
This is what I created for that purpose, you can call static and static methods, not a great solution but it does the job.
