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

I'm not exactly sure what i changed, but my project is running as an applet and not an application anymore so therefore its trash. How do i go back to application? You'd think there would be something on the internet for this..
when you right click to do "Run as ..." you should also see "Run Configurations" - click on this. On the left side you will see Applets, delete what is below this.
I am writing a web app with java. I am curious to know if there is a way that I can switch between the browser window (running the web app) and a local Java client application window (standard Java window). The Java Window is Oracle Forms.
For example, when i'm running the web app in my internet browser and I click a button. I want the button to execute process to switch from the internet browser window to the local java/forms window. Thus I would need something to execute on the OS level to switch my window.
How could I do this? I'm interested in any idea that would make that usecase work. For example, I probably need to introduce and integrate new technologies with my app? Probably a Java Applet?
Thank you,
Gavin
I am trying to create an application using SWT Browser. Is it possible to integrate Google Chrome as browser into Eclipse (not as external web browser)?
No, as of current stable release of google chrome, you cannot use it inside SWT. The reason is that google chrome (and essentially chromium) doesn't support ActiveX (like IE, Firefox, Safari etc) but is based on NPAPI. (Note: I am considering that you are working on Windows machine as you haven't mentioned in your question !!)
But there are projects which are trying to make an embeddable version of chromium. See these links:
Chromiumembedded
Is Google Chrome embeddable?
You can set it through Eclipse UI.
Goto : Window > Preferences > General > Web Browser
Select "Use External Browser" radio button
Click "New" button to add a new browser eg. Chrome !
Click Apply + Ok
... and you have it working !
Bug 405031 - [Browser] implement Chromium support
https://bugs.eclipse.org/bugs/show_bug.cgi?id=405031
If you can not make it through UI, Try to edit settings in the following file.
YOUR-WORKSPACE\.metadata\.plugins\org.eclipse.core.runtime\.settings there will be a file called org.eclipse.ui.browser.prefs open it with any text editor and change the appropriate values, It is self descriptive you can easily find out what to change and all. Have a back up of the same before you modify.
Hope this helps you.
EDIT: Restart your eclipse to effect the above change.
To integrate Chromium into Eclipse or SWT applications you can use https://github.com/equoplatform/chromium-swt.
I just wanted to ask, how can we open Java Applet like a program, but not an application integrated in a web page.
You push a button in web page and java program will start, but not a java applet integrated in a web page.
Or like a webpage but without address bar :)
This is possible somehow , right?
Thank you for your time and for your answers!
UPDATE
This would be like a solution: http://orangoo.com/labs/greybox/normal_usage.html
Greybox!
Everything is okey, except you cant drag / move that popup window anywhere. Maybe someone is familar with Greybox and can suggest how this is possible? ( To move popup window)
:)
How about using Java Web Start technology instead?
http://docs.oracle.com/javase/tutorial/deployment/webstart/
Java Web Start software provides the power to launch full-featured
applications with a single click. Users can download and launch
applications, such as a complete spreadsheet program or an Internet
chat client, without going through lengthy installation procedures.
With Java Web Start software, users can launch a Java application by
clicking a link in a web page. The link points to a Java Network
Launch Protocol (JNLP) file, which instructs Java Web Start software
to download, cache, and run the application.
When using Run As -> Web Application for a GWT app in STS, a Development Mode view is opened that contains a clickable link that in turn opens a browser and tests the GWT app...
What are the rules behind changing code while the code is running in the Development Mode. Does the Development Mode reflect these changes? Do you always have to terminate and restart Development Mode?
Any tips for how to speed up the loading of the link in Development Mode?
I would pose the same questions for Debug As -> Web Application.
Thanks!
The answer really depends on if you are running with "Debug As" or not. Actually, the whole topic is a little bit more complex (differentiating between server side/client side code, restarting vs refreshing vs reloading, ...), and instead of repeating myself, I will just provide you with a link to my answer here.
Note: The Google Plugin/GWT SDK behavior isn't specific to STS.
No, you don't have to restart. Just saving the files is sufficient. Another way to develop is to debug as a GWT app and then open the hosting html/jsp page in a browser and add the &gwt.codesvr=9997 at the end of the URL.
