I have created an menu in which there are different operation. When the user click's on the item's it should invoke another midlet respectively.
Or is there any other way of doing it?
I tried this code: previous = PushRegistry.registerAlarm("m", 0); to transfer to another midlet but it gives an exception:
java.lang.ClassNotFoundException: No MIDLet-<n> registration
m is the midlet present in the same package.
API documentation for the method PushRegistry.registerAlarm explains why you are getting the error:
Throws:
...ClassNotFoundException - if the MIDlet class name can not be found in the current MIDlet suite or if this class is not included in any of the MIDlet-<n> records in the descriptor file or the jar file manifest or if the midlet argument is null...
Given the error message about No MIDLet-<n> registration, one of the possible error reasons listed above appears to fit your case: "class is not included in any of the MIDlet-<n> records".
If you are interested in how to properly use PushRegistry functionality, consider studying introductory tutorial, like eg one recommended at Learning Path: Getting Started with MIDP 2.0:
The MIDP 2.0 Push Registry is a comprehensive article that shows you how to get your MIDP 2.0 application to respond to incoming network connections...

I want to get the media stream url from onvif,but it shows that "Method 'GetStreamUri' not implemented: method name or namespace not recognized"Detail: [no detail] .
I don't know the reason why the method GetStreamUri not implemented?
I download wsdl "http://www.onvif.org/ver20/media/wsdl" and generate the code by using the gsoap.
console ouput
I find the TEST.log.It shows that it cannot find ns3:GetStreamUri and ns1:GetStreamUri

Is your camera Profile T compliant or does it at least implement Media Service 2?
In not, then you should use Media Service 1.
I am using Mvvmcross crosscore in my project
I am trying to bind my loginviewmodel to the loginviewcontroller
I bound a command for the login button. the app waits until it gets a login response, which is stored in the loginViewModel itself..
How can I communicate this to the loginviewcontroller --- regarding the login status and login error message if any
Can I access the viewmodel datacontext inside my loginviewcontroller ??? and how ?
What is the best approach to communication any items in the viewmodel back ( I basically mean all the NON-UI binding items)
I am using Mvvmcross crosscore in my project
I'm assuming from this that you followed the CrossLight sample N=39.
Can I access the viewmodel datacontext inside my loginviewcontroller ??? and how ?
If you followed N=39. then you can access the DataContext using the property called DataContext - see https://github.com/MvvmCross/NPlus1DaysOfMvvmCross/blob/master/N-39-CrossLight-Touch/CrossLightTouch/MyViewController.cs#L33
public object DataContext
{
get { return BindingContext.DataContext; }
set { BindingContext.DataContext = value; }
}
Beyond this, there are many other examples in the N+1 videos which demonstrate how to communicate between ViewModels and Views including error messages and loading dialogs - e.g. N=34 shows one implementation of progress dialogs - https://github.com/MvvmCross/NPlus1DaysOfMvvmCross/tree/master/N-34-Progress
A complete index of N+1 videos is available on http://mvvmcross.wordpress.com
Obviously not all of these are appropriate for your CrossLight approach to development, but this is where you can allow your custom mvvm approach to fill the gap - it's code for you to write in your custom framework.
One of the best methods solving viewmodel interdependencies is using a loosely coupled approch using the MessageBus/Event Aggregator pattern. There's a plugin for MvvmCross. Or you could use the excellent TinyMessenger.
In principle when using this approach, you no longer establish hard references between the publisher and consumers of arbitrary notifications. Instead notifications get published on a message bus and every one is free to listen and subscribe.
I have created an iPad storyboard application using the newest version of Monotouch. My first screen is a login screen that I only want to show if the user has not saved his credentials. If credentials are available I want to instead navigate to the UITabBarController that is the second scene. I can't seem to find any documentation on how to do this. I tried creating an instance of the UITabBarController and pushing to it but it does not work.
homeScreen = new HomeTabBarNavigator(this.Handle);
this.NavigationController.PushViewController(homeScreen,true);
HomeTabBarNavigator is a UITabBarController that is already linked to other scenes. I get the following error:
[ERROR] FATAL UNHANDLED EXCEPTION: System.NullReferenceException: Object reference not set to an instance of an object
I assume I am getting this error because I have not defined any views to the ViewControllers property of my HomeTabBarNavigator. I was hoping that those views were already defined but that does not seem to be the case. Any ideas.
The best solution I could find is to call PerformSegue on the controller. Here is some example code:
this.PerformSegue("LoginSegue",this);
The controller that is loaded is the LoginController, and LoginSegue is a Segue that points to the HomeTabBarNavigator. While it is not perfect, the applications loaded the tabbar properly.
I used this stackoverlflow iOS question as the basis for my solution.
I was wondering if it's possible to open doc, xls, pdf, etc files using the "Documents To Go" app from a third party blackberry app.
If you want to open a specific document, since Docs ToGo registers to handle these extensions, you can use the Registry invocation and it will be handled for you. Take a look at the Registry and Invocation classes, the following code will open the document in the given path, Docs ToGo will take over through the Registry:
Invocation invocation = new Invocation(path);
Ragistry reg = = Registry.getRegistry("<your app namespace.class>");
reg.invoke(invocation);
If there is no registered handler for the file content type a ContentHandlerException will be thrown with error code ContentHandlerException.NO_REGISTERED_HANDLER.
Note: there's a small bug in Docs ToGo - closing the document or clicking the back button might not lead the user back to your application.
EDIT: The getRegistry function takes a class fully qualified name e.g. com.softartisans.SilverDust, where SilverDust is the class mane. You can find more info about the use of the Registry in this online book starting page 291 - Client use of Registry. I originally linked to the javax Registry, but it is more useful to look at the BlackBerry Registry docs.
You can use the ApplicationManager class to launch other applications, for example by looking up its descriptor and using runApplication(). You can also pass arguments in the descriptor and if the application looks at arguments passed into it, it may actually open the specified file.
I want to set different themes to my Vaadin application, depending on the user agent.
In particular I want to distinguish at least between mobile devices (iPhone, Android,...) and desktop web browser.
Vaadin's API reveals two interesting classes:
BrowserInfo
WebBrowser
BrowserInfo seems to do the job perfectly for my needs, but fails on instancing via its get-method:
SEVERE: javax.servlet.ServletException: ...
Caused by: java.lang.UnsatisfiedLinkError: com.vaadin.terminal.gwt.client.BrowserInfo.getBrowserString()Ljava/lang/String;
Couldn't find a way to access WebBrowser from within my application either.
Did I choose the right approach for browser distinction?
Why does accessing BrowserInfo fail?
As #quickanalysis pointed out, you've to be aware of the separation of client-/server-side components.
For getting the user agent string on server-side, the following code snippet does the job:
ApplicationContext context = this.getContext();
if (context instanceof WebApplicationContext) {
String userAgent = ((WebApplicationContext)this.getContext()).
getBrowser().getBrowserApplication();
}
From what class you are trying to call this method? The BrowserInfo is available at client-side as WebBrowser ar the server-side. Take a look at the package naming.
