Cef Browser is showing blank

[suchira]

I have a swing based app where I am trying to display cefbrowser in a panel. However while running my app the browser is not showing up in the panel. In the console I am seeing the following being printed

Using:
JCEF Version = 84.3.8.266
CEF Version = 84.3.8
Chromium Version = 84.0.4147.105
initialize on Thread[AWT-EventQueue-0,6,main] with library path D:\org.jcef\libs

Is there a reason for you to try with such an old chromium version? Have you considered using jcefmaven to bootstrap your jcef environment?
Apart from those two questions your post does not provide enough details to help you out. Can you add some more information? Like what your D:\org.jcef\libs folder looks like, what your code looks like...

Hi Friwi,

There are certain restrictions in my organization due to which regular upgrades are not possible and hence I am using the mentioned chromium version.
I am not aware of jcefmaven.
The D:\org.jcef\libs contains all the related jcef dlls which are used for showing the jcef browser.
Please find below some of the code snippets
I have created a java class where inside the main method I am trying to get a jpanel containing the cefbrowser and I am embedding it inside contentPane of JFrame.
JPanel contentPane = new JPanel();
contentPane.setBorder( new EmptyBorder( 5, 5, 5, 5 ) );
contentPane.setLayout( new GridLayout( 1, 2 ) );
TestSwing frame = new TestSwing();
frame.setContentPane(contentPane);
frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
frame.setResizable(true);
frame.setVisible(true);
JCEFBrowserPanel hostedAWPanel = hostingAPIs.getJCEFSwing();
if( hostedAWPanel != null ) {
contentPane.add(hostedAWPanel);
hostedAWPanel.setPanelReady();
contentPane.setVisible(true);
frame.setVisible(true);
}

In the above code this API getJCEFSwing returns us a JPanel with cef browser embedded. Please find below the code of how we are embedding the cef browser inside JPanel

final ControlPanel controlPanel = new ControlPanel( JCEFBrowserPanel.this, m_browser.getBrowser() );

n the above code m_browser is an instance of our internal API where we create the browser by the below code
if( m_browser == null )
{
m_browser = client_.createBrowser( "about:blank", false, false, null );
m_browser.createImmediately();
}
In the above code the client is CefClient.
In the API where we are creating the m_browser we are also implementing CefMessageRouterHandlerAdapter and CefMessageRouterConfig

Hmm, I can not diagnose the error from the information that you have given. There are just too many variables.

As a general note, I would like to suggest migrating to jcefmaven in your organization. It will greatly reduce your effort to get jcef running inside your application on all platforms and if any errors arise in the future it will allow for one central fix - not all developers fixing the same bug individually.
