I have a jodd project that uses Proxetta and JTX for creating transactions over services classes. The issue is that when I try to debug a service class I receive :
Unable to install breakpoint due to missing line number attributes
I suspect that there has something to do with they way Proxetta generates my proxies classes as it seems that in Spring if you have no interface for a class the same happens.
I use Eclispe and here how Proxetta is initialized:
public void initProxetta() {
ProxyAspect txServiceProxy = new ProxyAspect(AnnotationTxAdvice.class,
new MethodAnnotationPointcut(Transaction.class) {
#Override
public boolean apply(MethodInfo mi) {
return isPublic(mi) &&
isTopLevelMethod(mi) &&
matchClassName(mi, "*ServiceImpl") &&
super.apply(mi);
}
});
proxetta = ProxyProxetta.withAspects(txServiceProxy);
proxetta.setClassLoader(this.getClass().getClassLoader());
}
Would you please try the following quickstart webapp1 example?
Its gradle project, so you can quickly import it in any IDE. In this example, we create proxy almost exactly like you above, but on actions (which should not make a difference). Now try to put a breakpoint into the IndexAction - this one gets proxified, for example. I am able to put break point there in IntelliJ IDEA.
Moreover, I dunno why Eclipse complains about the breakpoint in the service implementation class, since Proxetta as you used above creates a proxy subclass, and does not change the target class in any way. So when you put breakpoint in the service implementation code, it is in your class, not proxy class.
Finally, did you put BP on the method, or inside the code? If it is the first (on the method), then please try to put the BP inside the code of your service: eg on first line of the method body.

I've just started digging into the new ASP.NET 5 by creating a test single page application with the OAuth login. I already know that I can use IdentityServer3 for that purpose and it seems pretty nice. I've found a post by Dominick Baier which is explaining how to set up the IdentityServer3. However, the post seems to be out of date or the identity server itself isn't working with the latest version of the ASP.NET 5 (which is beta7 at the moment).
The problem is, when I try to configure the IdentityServer in the Startup.cs I got an error from VS telling me that IApplicationBuilder has no extension method called UseIdentityServer. And this seems to be true, since in the IdentityServer3 source code they have this extension method declared for IAppBuilder (not IApplicationBuilder).
Here is my code (Startup.cs):
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
// Add MVC to the request pipeline.
app.UseMvc();
var options = new IdentityServerOptions
{
Factory = new IdentityServerServiceFactory()
};
app.UseIdentityServer(options);
}
And the error (on the last line) is
'IApplicationBuilder' does not contain a definition for 'UseIdentityServer' and the best extension method overload 'UseIdentityServerExtension.UseIdentityServer(IAppBuilder, IdentityServerOptions)' requires a receiver of type 'IAppBuilder'
Obviously, if I change the parameter type in the Configure method to IAppBuiler, it'll throw a runtime error because the dependency injection will not be able to inject that type. Even if it would, I'd lose the UseMvc() extension method.
So could you point me in the right direction please?
Perhaps I'm just missing something tiny but crucial here.
Thanks in advance!
I have one Windows Handheld device application which has the requirement of accessing a REST API. The REST API gives me JSON output which I am going to handle via Newton.JSON. Now to achieve modular structure I want to have the communication to the REST API be handled via a different module altogether something like a Class Library. But unfortunately it seems that it is not possible to do so via a class library(or maybe possible). So my question is what is the best alternative to do so?
Please note that I don't want to include those connectivity operations in my front end application project. And I am using .Net framework 3.5 & Windows Mobile SDK 6.0
Thanks in advance
Pseudo class library code:
public function void startQuery() //starts a thread that does the JSON query
//inside thread on query result use OnDone() delegate
private delegate void OnDone(string dateTimeString);
//In main GUI code add a reference to the class lib and init a new object then add an event handler to the OnDone delegate of the class lib
JSONClassLib myJson=new JSONClassLib();
...
myJson.OnDone+=new EventHandler(myEventHandler);
void myEventHandler(sender this, objext o){
//will be called when query is done
}
//you need to use Control.Invoke if you want to update the GUI from myEventHandler
//to start a query use something like this from your class lib
myJson.doQuery(string);
If you add your existing code we may help with creating a class lib and async code
Now I got my answer. Sorry I did a mistake while selecting the project type. I selected "Windows Form Class Library" project instead of "Smart Device Class Library" project. Now that I have selected the right one it is working fine for me.
BTW thanks for those responses.
Cheers
I´m developing an App that will be available for Windows Phone 8 and the Windows Store. To reduce redundancy I´m using a Portable Class Library (PCL) and on top of that I'm trying to apply the MVVM pattern with the help of the MVVM Light PCL Toolkit. The ViewModels are placed in the PCL and are bound directly in the XAML of the Apps pages.
When the data is received without an error, everything works fine. But I don´t know how to get the exceptions/error message back to the App when errors do happen.
Inside the Windows Store App errors will show as a MessageDialog while the Wp8 App will use the MessageBox class. Obviously the PCL isn´t aware of any of these classes. What I´m not getting is how to know if a ViewModel ran into an error, and how to get the message inside the App. Is this even possible when the ViewModels are bound inside the XAML?
The code in the ViewModel (inside the PCL) looks like this:
DataService.Authenticate((token, error) =>
{
if (error != null)
{
// This is, obviously, not going to work.
MessageBox.Show(error.Message);
return;
}
Token = token;
});
So I have to save the error somehow and let the App itself know the error has occurred, and then call the matching way of showing the error to the user.
Currently I´m thinking of something like defining an Error-property inside the BaseViewModel and fill it when errors in the ViewModel occur. Then, in the CodeBehind of the pages, make them aware of the current ViewModel and bind a PropertyChanged-event to this Error-property. But I was not able to implement it yet, so I don't know if this is even the right way to go.
Do I have to step down from the idea to bind the ViewModels inside the XAML, and do I instead have to initialize them inside the pages Codebehind?
Your instinct is correct, but there are more than a few ways of going about this.
First and foremost, you can use Mvvm's Messaging library, which will allow your ViewModel to send messages directly to your View. Your View can then handle it in any way it wishes, including but not limited to using a MessageDialog.
Secondly, you can also create a Function or Action (likely the former) in your ViewModelLocator for ShowMessageDialog. This Function will likely take a string and return a Task. Then, after you initialize your ViewModelLocator initially, you can inject your ShowMessageDialog code. Your ViewModels can then use whatever platform's MessageDialogs that they please.
Ex:
Note: This code uses the BCL Async libraries that are accessible in Nuget. They work in the PCL just fine.
ViewModelLocator:
public static Func<string, Task> ShowMessageDialog { get; set; }
App.xaml.cs:
ViewModelLocator.ShowMessageDialog = (message) =>
{
// For Windows Phone
return TaskFactory.StartNew(() => MessageBox.Show(message));
// For Windows 8
MessageDialog md = new MessageDialog(message);
return md.ShowAsync().AsTask();
};
ViewModel:
await ViewModelLocator.ShowMessageDialog("This is my message.");
Secondary Note: The md.ShowAsync().AsTask(); must be run on the UI Thread. This means that you will have to invoke it via the dispatcher in the case that you are running it in a task asynchronously. This is possible using a similar method of injecting the use of the app's CoreDispatcher via the RunAsync method.
This means that you can, on any platform (Windows 8 and Windows Phone shown above), inject whatever Message Dialog system you want and use it in your PCL.
I would say that it is much easier to do the first method I suggested, as that is what it is there for, but the Function method version is definitely helpful at times.
I'm using PHPStorm v3 and have some code which connects to a certain SOAP service. (via a simple PHP SoapClient) No problems whatsoever. But the PHPStorm inspector cant find the methods available of the WSDL and thus cant recognize the used methods:
$this->soap = new SoapClient('somewsdl url');
$issues = $this->soap->getIssuesFromJqlSearch($this->auth,
'ticketId = '.$ticket->getId().'
AND impId ~ "'.$currentImplementation->getIdentifier().'"', 1);
Everything works but the method 'getIssuesFromJqlSearch' which is provided by the external WSDL is highlighted with the mentioning of an undefined method... How can i 'tell' PHPStorm what should/could be used (or explain how to parse the WSDL?)
You can suppress the inspection for this statement from the Alt+Enter, right arrow menu:
This is not perfect, since it does not parse the WSDL and you have to do it manually, but works fine after the initial setup.
Create a class extending the native SoapClient and use annotations to add virtual methods:
/**
* #method mixed getIssuesFromJqlSearch
**/
class VendorSpecific extends \SoapClient {}
Or you could generate such client yourself, implementing all the methods as a proxy to self::__soapCall(). See my SoapClient generator for reference. The upside is that it can parse the WSDL, though not perfectly.
Without looking into JUnit source itself (my next step) is there an easy way to set the default Runner to be used with every test without having to set #RunWith on every test? We've got a huge pile of unit tests, and I want to be able to add some support across the board without having to change every file.
Ideally I'm hope for something like: -Djunit.runner="com.example.foo".
I don't think this is possible to define globally, but if writing you own main function is an option, you can do something similar through code. You can create a custom RunnerBuilder and pass it to a Suite together with your test classes.
Class<?>[] testClasses = { TestFoo.class, TestBar.class, ... };
RunnerBuilder runnerBuilder = new RunnerBuilder() {
#Override
public Runner runnerForClass(Class<?> testClass) throws Throwable {
return new MyCustomRunner(testClass);
}
};
new JUnitCore().run(new Suite(runnerBuilder, testClasses));
This won't integrate with UI test runners like the one in Eclipse, but for some automated testing scenarios it could be an option.
JUnit doesn’t supporting setting the runner globally. You can hide away the #RunWith in a base class, but this probably won't help in your situation.
Depending on what you want to achieve, you might be able to influence the test behavior globally by using a custom RunListener. Here is how to configure it with the Maven Surefire plugin: http://maven.apache.org/plugins/maven-surefire-plugin/examples/junit.html#Using_custom_listeners_and_reporters
