Example 1 with IPlatformListener

use of org.eclipse.scout.rt.platform.IPlatformListener in project scout.rt by eclipse.

the class PlatformImplementorTest method doTestAwaitPlatformStartedFailsInState.

protected void doTestAwaitPlatformStartedFailsInState(final State platformStartFailsInState) throws Exception {

    // create platform instance and start it in another thread
    final TestingPlatformImplementor platform = new TestingPlatformImplementor(bean);
    Future<?> platformStartFuture = startPlatformInAnotherThread(platform);
    // current thread is expected to be suspended
    assertAwaitPlatformStarted(platform, platformStartFailsInState == null);
    // wait until platform starter has been finished and either expect no failures or the intended startup exception
    if (platformStartFailsInState == null) {
        platformStartFuture.get();
    } else {
        try {
            platformStartFuture.get();

        } catch (ExecutionException e) {
            assertSame(TestingPlatformStartupException.class, e.getCause().getClass());
        }
    }

}

Example 2 with IPlatformListener

use of org.eclipse.scout.rt.platform.IPlatformListener in project scout.rt by eclipse.

    if (m_beanManager == null) {
        // can happen if there is an error creating the bean manager. cannot move to status invalid. just do nothing.
