How can a MIDlet ascertain whether it has been manually invoked or automatically?
Thanks!
I can have a MIDLet with tasks A and B subclass the MIDLet with Task A and override "A" with "A + B". The auto invocation will be on the sub-class.
I presume automatic start is achieved with PUSH registry. Try this:
PushRegistry.listConnections(true);
If result is not empty application started automatically.

I'm trying to make a reshaprer plugin to add one (or more) configurations, besides executable, static method, project, at resharper's build/run window.
Any guidelines where to start? Or how to access build's context and configure?
Currently examining the JetBrains.IDE.RunConfig, SolutionBuilders etc but one help would be appreciated.
Should this plugin be a SolutionComponent or a SolutionInstanceComponent?
Resharper's sdk help lucks documentation on build/run component.
Thank in advance!
You can extend the available run configuration types by implementing IRunConfig and IRunConfigProvider.
The IRunConfigProvider class needs to be marked as [ShellComponent], and can derive from the RunConfigProviderBase abstract base class. You get to specify a name, e.g. "Executable", a type identifier, e.g. "exe" and an icon ID. There's also the CreateNew method, which will create a new instance of your IRunConfig class, which will be mostly unconfigured, at this point.
The IRunConfig interface doesn't need to marked as a component, and should also derive from RunConfigBase - take a look at RunConfigExe in dotPeek to see an example of how to implement. You should override Execute in order to actually run whatever it is you need to run. You can use the RunConfigContext class passed in to actually execute a process from a ProcessStartInfo, or an IProject - this will execute it either by running the process, debugging it, or something else, such as code coverage or profiling.
For an .exe, this is as simple as:
public override void Execute(RunConfigContext context)
{
context.ExecutionProvider.Execute(GetStartInfo(context), context, this);
}
But for a more complicated example, look at RunConfigMethod.Execute, which uses its own standalone launcher executable, and passes in command line parameters to load the correct assembly and execute the given static method.
Settings are implemented with ReadSpecific/SaveSpecific, and you can provide an editor view model with CreateEditor. You'll need a settings class, something like:
[SettingsKey(typeof (ConfigSettings), ".exe config")]
public class ExeSettings
{
[SettingsEntry(null, "Path to .exe")] public string Executable;
[SettingsEntry(null, "Working directory")] public string WorkingDirectory;
[SettingsEntry(null, "Command line arguments")] public string Arguments;
}
The view for the editor is provided by a WPF control that is displayed in a dialog that ReSharper controls. The view needs to be decorated with the [View] attribute and must implement IView<T> where T is the concrete class returned from CreateEditor. This is how ReSharper will locate the view for the view model returned by CreateEditor. Again, take a look at RunConfigMethodView in dotPeek for some more idea of what's going on (and if you look in the resources, you'll be able to see the XAML itself).
Because I found the method named bindThread() is invoked multiple times at class named StandardContext in Tomcat 7 source code, especially in the method named startInternal(). I do not understand why need to call this method multiple times.
Actually the bindThread() is set the thread context classloader, but I don't konw why still use bindThread() and unbindThread() method pair in the startInternal() invoke multiple times.
Web application start and stop normally happens with the container class loader in effect. Some parts of the start (and stop) process (e.g. firing the application listeners) needs to take place with the web application class loader in effect. bindThread() and unbindThread() are the methods that switch to the web application class loader and back again respectively. The various elements of start and stop have to happen in a specific order so it is necessary to switch back and forth between class loaders.
i'd like to ask the user "Are you sure that you want to quit the application?" question. If the user presses Yes, the application will terminate. If the user the presses No, the application will continue running. How do i do that?
I use visual c++ 2008 and mfc.
You need to handle the WM_CLOSE message, which can do in MFC by adding ON_WM_CLOSE to your CMainFrame class's message map, and providing an implementation of the OnClose function.
(The Class Wizard can do this for you.)
void CMainFrame::OnClose()
{
if (AfxMessageBox("Exit application?", MB_YESNO) == IDYES)
__super::OnClose();
}
__super is an MSVC extension that allows you to refer to the most immediate base class. If you are compiling in another compiler (unlikely for an MFC app), or using non-standard extensions makes you uncomfortable, you can substitute the actual name of the base class.
The approach suggested by Marijke is correct. But for it to compile you must add ON_WM_CLOSE in the CMainFrame message map, and you must use the actual base class where Marijke used CFrameWnd. (There are several possible base classes.) For example, the message map could look like this if the base class is CMDIFrameWndEx:
BEGIN_MESSAGE_MAP(CMainFrame, CMDIFrameWndEx)
ON_WM_CREATE()
ON_WM_CLOSE()
....
I made the program Test.jar which there is a menu to run another program (Hello.jar).
I've been looking for and get the following code
callLauncher("javaapp:midlet-name=Hello;midlet-vendor=Vendor");
and
PushRegistry.registerAlarm("Hello",now.getTime()+100);
but not successful - throws ClassNotFoundException. Is there another way?
API documentation for the method you use (registerAlarm) explains pretty clearly what you did wrong:
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
I have just started with Eclipse RCP.
I created Eclipse RCP View with TableViewer and WritableList to get data from other thread.
But I cannot see any changes. I need only to show content of List that other thread is managing.
public class View extends ViewPart {
private TableViewer viewer;
private WritableList input;
I also can get error,
org.eclipse.core.runtime.AssertionFailedException: assertion failed: Getter called outside realm of observable org.eclipse.core.databinding.observable.list.WritableList
I know what is UI Thread. I just don't know how to write. Please help with example.
UPDATE. Was not solved, because of lack of time, and missing good and focused tutorial.
I received this error message also with my code.
Databinding observables (WritableList, WritableValue...) inherit from ChangeManager, which provides ChangeManager#getRealm and the realm has Realm#exec. Within the runnable provided to exec, the operation runs in the correct thread.
This line caused the error (Getter called outside realm of observable):
WritableValue value = getEditor().getWritableValue();
System.out.println(((RcpEditorModel) value.getValue()).getNumber());
And this prevented the exception:
WritableValue value = getEditor().getWritableValue();
value.getRealm().exec(() -> System.out.println(((RcpEditorModel) value.getValue()).getNumber()));
The same will work with WritableList since it also inherits from ChangeManager.
