Some errors after starting jcef

[edominic]

I have a few strange errors after starting client.

Console output:

Code: Select all

Working Directory is not a bundle, so I set resource dir path and locales dir path:

Code: Select all

            cefSettings.locales_dir_path = "/workspace/xyz-client/Contents/Frameworks/Chromium Embedded Framework.framework/Resources";
            cefSettings.resources_dir_path = "/workspace/xyz-client/Contents/Frameworks/Chromium Embedded Framework.framework/Resources";

The weird thing is, that the browser loads/renders the content but it's not visible to me. The background is still grey but if move mouse over the invisible content, the mouse-cursor changes (on this page are some text boxes, buttons, ...). I could press button on the invisible page and it recognized by jcef.

The next weird thing is, if I add an JTextField for address entering to browser window, the web-content appears once I click on JTextField. (Some code for JTextField):

Code: Select all

   address_ = new JTextField(startUrl, 100);
      address_.addActionListener(new ActionListener()
      {
         @Override
         public void actionPerformed(ActionEvent e)
         {
            browser_.loadURL(address_.getText());
         }
      });

or if I resize window, then content appears, too.

"building" window:

Code: Select all

      getContentPane().add(address_, BorderLayout.NORTH);
      getContentPane().add(browserUI_, BorderLayout.CENTER);
      pack();
      setSize(800, 600);
      setVisible(true);

      addWindowListener(new WindowAdapter()
      {
         @Override
         public void windowClosing(WindowEvent e)
         {
            dispose();
            cefApp_.dispose();
         }
      });

What's wrong here??? Oo :/

Edit:
I already read through the other threads, but they didn't help me

Little update to my errors:
The problem with "Could not load cef.pak" is gone now... It was my false...
The path to CEF Resources was wrong -.-" Overlooked it all the time.

The problem with invisible content is still there, so I need help with this.

And I got another problem. Here some console outputs:

As you can see, it's DevTools related... That's my problem, can't open dev tools. Only a white screen. The same, if I try to set remote debug port and try to connect via Chrome Browser

[edominic]

Added bug report to jcef : https://bitbucket.org/chromiumembedded/java-cef/issue/164/getdevtools-fails

Would be really nice, if someone could help me :/

[edominic]

Really no one can help? -.-"

I don't know what to do or where to look into to fix myself :/

[edominic]

I don't know, if there is a bug:

console output:

But if I look into Actifitymonitor in my process and then "Opened files and ports", the icudtl.dat is listened there with the right path.

[edominic]

Found a bug-report about the problem with icudtl.dat... It's a chromium problem :/
Link: https://bitbucket.org/chromiumembedded/java-cef/issue/109/linux-mac-fix-discovery-of-icudtldat

I would fix this on myself, but there is another problem with CEF :/
I downloaded 2171 Branch of Chromium and CEF (with latest automate script), but if I build them, Chromium Embedded Framework got a version number of 351.8.123 but libjcef wants 32069.8.123

Code: Select all

  Referenced from: /workspace/xyz-client/processes/Contents/Java/libjcef.dylib
  Reason: Incompatible library version: libjcef.dylib requires version 32069.8.123 or later, but Chromium Embedded Framework provides version 351.8.123

Having the same problem. .pak files are loaded, but no content shown on the page, and there seem to be some elements rendered.

Any progress on this issue?

[edominic]

The problem is, jcef needs to be build against the same apple-sdk as java is built against.
the newer versions of jcef are built against sdk 10.9 (I think) but java is still 10.8.

Thanks for the reply.

Does this affect only the displaying of the webpage rendered? Or does it affect some other parts as well? Personally I won't need the visual rendering anyway, so I'm wondering if I can still use all other functionalities using this build.

[nala]

Actually fixed the rendering. The MainFrame.java test I was using, had OffScreenRendering set to false for Mac.

Now your conclusion for the sdk versions confuses me..
