Here is an "Hello World" applet is given on Oracle's it works online. Oracle has also provided these tutorial as offline version. In download files of same website applets are not working rather these are being blocked by Java setting. There was also message that I can change security settings from Java Control Panel. I changed settings from high to medium but applet is sill being blocked by Java.
Click on the Start button and then click on the Control Panel option.
In the Control Panel Search enter Java Control Panel.
Click on the Java icon to open the Java Control Panel.
In the Java Control Panel, under the General tab, click Settings under the Temporary Internet Files section. The Temporary Files Settings dialog box appears.
Click Delete Files on the Temporary Files Settings dialog. The Delete Files and Applications dialog box appears.
Click OK on the Delete Files and Applications dialog. This deletes all the Downloaded Applications and Applets from the cache.
Click OK on the Temporary Files Settings dialog. If you want to delete a specific application and applet from the cache, click on View Application and View Applet options respectively.
Now try to run your applet again and it should work.

I am testing web site functionality with Selenium using Java from Eclipse. One test is to click a "download" button, look for a popup window (this is another selenium window), respond to that window which should then cause a Windows download dialog to pop up (please see attached image).
Please note. I do not have to actually download the file. Just verify that the windows dialog popped up.
I know from experience (or at least am unaware) that Selenium can actually access the Windows download box, choose a file location and start the download. But all I need to do is verify that the download box popped up. Exiting the chromedriver will kill the download window so it won't linger but I still need to verify it was created.
Any suggestions? One thing I tried was having the task manager open. I thought I could find a process corresponding to the dialog box, but there were 119 processes before the dialog box came up as well as when it was up. So any suggestions what to do?
I could add as an aside that someone wrote a workaround to actually download the file. Instead of clicking on a button or link he pretended to be the Windows dialog box and accepted the download. That, for reasons I stated above, will not work in this instance as I have to verify the actual results of clicking the button.
Please see my attached image for an example of the dialog box.
One workaround to meet this test requirement is, once you responds to the window which results in a Windows download dialog, try performing the next action. This will result in a WebDriverException as the access to UI will be blocked by the Windows dialog. You can then catch this WebDriverException and in the catch block press escape key using Robot class in Java. Following is an example:
try {
//1) Respond to the window that results in Windows dialog box.
//2) Perform the next action on UI.
} catch (WebDriverException we) {
//3) You can capture screen shot as well at this stage.
System.out.println("Most likely Windows dialog appeared.");
//4) Press escape key using Robot class in Java
Robot r = new Robot();
r.keyPress(KeyEvent.VK_ESCAPE);
}
You can use AutoIT to check if the windows dialog appears, then save the status of the windows dialog in somewhere(eg. a temp file), then you read the status of the windows dialog using Java from Eclipse
I work on Eclipse Luna on my windows 7, the java version insatlled on the computer itself is up to date.
I build some simple JApplet to see how it runs on an html page in my computer. I mean not through
'run as applet' in eclipse, rather on a real html page.
But I can not run it due to the restriction - "Application blocked by java security". How can I see it? do I must get certificate for just simple trial?
If yes, how to do it with eclipse? Is it a short procedure? Can I see the applet runs without it?
Thanks in advance, Liron
Are you sure that you have enabled Java for your web browsers? Here are instructions for Internet Explorer:
Click Tools and then Internet Options
Select the Security tab, and select the Custom Level button
Scroll down to Scripting of Java applets
Make sure the Enable radio button is checked
Click OK to save your preference
Consider simple application, that display list of file. I would like to display context menu , when user click of file or folder, the same as, when user right mouse click in windows explorer (open, rename, edit etc.). I don't want to create my own context menu, I want to show windows os context menu, using some kind of winapi probably. This should works only on windows machine.
Is it possible to achieve it with Swing or SWT or any other UI controls ?
This MSDN article explains how it is done:
Windows Explorer calls a folder object's IShellFolder::GetUIObjectOf to request an interface for one of the objects.... When a user right-clicks an object, Windows Explorer requests an IContextMenu interface.
There is a full source code example in C here.
On Windows 7 an application can control how to group their Windows on the taskbar. Windows has some default settings related to the executable, how the shortcut was created, the name of the program, etc. to apply some default grouping. The problem with host based applications like Java, is that the same executable is used by many programs so Windows has some registry settings to set that javaw.exe is a host app. When this happens, applications must configure at runtime how to group Windows and enable pin to taskbar. I am already setting Application User Model IDs in order to group Windows as needed.
The problem that I haven't found solution is that for a multi window application: how to set a stable icon to be used on the taskbar?. The default Windows behavior for an application, say for example with two windows, where each windows has his own icon, the task bar icon shows the icon of the first opened window, if that window is closed it changes to the other one, and the process is repeated every time windows are opened and closed.
There is some API to set the icon when the user pin an application to the taskbar setting System.AppUserModel.RelaunchIconResource window property, but the documentation says that this icon is used when the app is being pinned, so according to that it only is used if the application is running from that pinned applications, leaving the problem open for applications that are not able to be pinned (or that the developer do not want to allow pinning).
There are options like generating a new executable with the icon (launching the JVM from that application), creating a shortcut with the correct AppUserModelID. Those aren't solutions for me because the application is distributed using Java WebStart/JNLP, so the application shortcut is created by Java and the launcher is a marked as a host application (as it should)
the other solution is to set the same icon to each window when running on Windows 7, that icon, with the exception of the taskbar one, is not very prominent on Windows 7 on Aero mode, but with Aero disabled it is, it is the icon used on the Alt+tab switcher without windows previews, something I want to leave looking different for each windows
Note: This is a tagged Java but really is a question for any platform that use a host executable (javaw.exe, python.exe ...)
During automated testing using Selenium-2 we are clicking on the link and which opens the "File Download" window. And I want to click on "save" button and save the file to the disk.
Selenium2 doesn't support handling of filedownload on its own. So I have written a AutoIT script to click on the save button and it works successfully if we are testing the web application on the local machine. In remote machine if I am running this script it hangs if I close the Remote Desktop (RDP).
One thing is we don't know what will be the link which will be clicked. We will be only knowing that one "File Download" window is existing and which may not be on the top or active. But I need to click on save button.
So, is it possible to handle file download popup window in other way?
If we can handle it AutoIT then its very good. but other than AutoIT suggestions are also welcome. Like if we can do using some other APIs or scripts. But to run the script/solution it would be good if we do not need to install any other software.
