Can't create client

[edominic]

Another problem here :/
In my test project, it works fine. But now I am trying to integrate JCEF in our main application.
I don't get any errors.

Here is an example code:

Code: Select all

CefApp xyzApp = CefApp.getInstance(); // works fine
CefClient xyzClient = xyzApp.createClient(); // hangs in this function

The same way it works in my test application (its exact same code).
If I debug through this code I see, that the application "hangs" at:

Code: Select all

            public void start() {
                if(!this.isAlive() && super.getState() == State.NEW) {
                    CefApp.this.lock.lock();

                    try {
                        if(SwingUtilities.isEventDispatchThread()) {
                            CefApp.this.initialize();
                        }

                        super.start();
                        CefApp.this.cefInitialized.awaitUninterruptibly(); // <-- Here it hangs/waits
                    } finally {
                        CefApp.this.lock.unlock();
                    }
                }

            }

in CefApp in JCEF.jar

I copied the content of jcef_example_app to ourprojectpath/Contents and passed java.library.path to it:

Code: Select all

-Djava.library.path="/workspace/xyz-client/Contents/Java/:/workspace/xyz-client/Contents/Frameworks/Chromium Embedded Framework.framework/Libraries"

(IntelliJ VM-Options)
and tried to add resources-argument like mentioned http://www.magpcss.org/ceforum/viewtopic.php?f=17&t=11884.

CefSettings:

Code: Select all

      CefSettings cefSettings = new CefSettings();
      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/";
      cefSettings.log_severity = CefSettings.LogSeverity.LOGSEVERITY_VERBOSE;
      cefSettings.log_file = "/workspace/xyz-client/jcef.log";

      CefApp = CefApp.getInstance(cefSettings);

Some hints for me? Is there a way to get some logs of CEF?

Here some output of console while runtime (last few lines):

Code: Select all

Edit:
Some information...
MacOsX10.10 with IntelliJ 14 and Java8
(I read about, to set working directory to example jcef app bundle, but its no possibility for me (and I can't test it)

After playing around with it, I got following error:

It crashes in

I created another little test project.
My steps:
- I build latest jcef sources
- In project set working directory to /pathtojcef/src/xcodebuild/Debug/jcef_app.app/
- Added external Library/Libraries (/pathtojcef/src/xcodebuild/Debug/jcef_app.app/Contents/Java/)

If I build and run my project it works fine, without any problems.
Then, next steps:
- In project set working directory to /workspace/xyz-client/
- Changed external Library/Libraries to /workspace/xyz-client/Contents/Java/
- Added client settings:

Code: Select all

        CefSettings cefSettings = new CefSettings();
        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";
        cefSettings.log_severity = CefSettings.LogSeverity.LOGSEVERITY_VERBOSE;
cefApp_ = CefApp.getInstance(cefSettings);

If I build and run my project, I get following errors:

Code: Select all

The "Contents" directory of xyz-client is exact the same as the "Contents" directory of jcef_app.app

Is this a bug of jcef? I get the same error messages, if I leave CefSettings.

I hope you can help me, because I need this :/ It's important

Edit:
After playing around with settings, here maybe some important information.
Settings1: <-- Works fine
- Working directory in jcef_app.app
- external library (jcef.jar) in jcef_app.app/Contents/Java/
- no additional CefSettings

Settings2: <-- Works fine, too
- Working directory in /workspace/xyz-client/
- external library (jcef.jar) in jcef_app.app/Contents/Java/
- no additional CefSettings

Settings3: <-- Doesn't work
- Working directory in jcef_app.app
- external library (jcef.jar) in /workspace/xyz-client/Contents/Java/
- no additional CefSettings

Settings 4: <-- Doesn't work
- Working directory in /workspace/xyz-client/
- external library (jcef.jar) in /workspace/xyz-client/Contents/Java/
- CefSettings for resource and locale path

Result: Once I don't use Java path in jcef_app.app, Application doesn't work any more.
Again, Contents directories are both exact the same

I debugged the native code to the point, where it hangs/waits.

In Java, it is this point:

Code: Select all

CefApp.this.cefInitialized.awaitUninterruptibly();

In native, its this point:

Code: Select all

bool CefInitializeOnMainThread(const CefMainArgs& args,
                               const CefSettings& settings,
                               CefRefPtr<ClientApp> application) {
  SystemStub* stub = [[SystemStub alloc] initWithValues:args
                                               settings:settings
                                            application:application];
  // we're not using waitUntilDone here because we want to return true
  // or false to the caller of this method.
  g_lock_initialize = [[NSCondition alloc] init];
  [g_lock_initialize lock];
  [[CefHandler class] performSelectorOnMainThread:@selector(initialize:)
                                       withObject:stub
                                    waitUntilDone:NO];
  [g_lock_initialize wait];
  [g_lock_initialize unlock];
  [g_lock_initialize release];
  [stub release];
  return g_init_result;
}

It hangs/waits at

Code: Select all

  [g_lock_initialize wait];

and does nothing.
It is in util_mac.mm at line 430.

Any idea?

only appears, if flags "-Xcheck:jni" and "-verbose:jni" are set

Some additional information about hang/wait problem.

In our application, we're working with multiple processes.
- Main process
- Browser process
- ... some other not namable processes

Browser process is handling jcef.

Main process starts Browser process, browser process ist called with vm option "-XstartOnFirstThread"
The problem is this vm option, if it's set, the application hangs/waits, if this option is not set, it starts (but I have to test our application, if this option is still necessary)
