/**
 * Embeddable Glassfish app client container (ACC).
 * 

* Allows Java programs to: *

    *
  • create a new builder for an ACC (see {@link #newBuilder} and {@link AppClientContainerBuilder}), *
  • optionally modify the configuration by invoking various builder methods, *
  • create an embedded instance of the ACC from the builder using {@link AppClientContainerBuilder#newContainer() }, *
  • startClient the client using {@link #startClient(String[])}, and *
  • stop the container using {@link #stop()}. *
*

* Each instance of the {@link TargetServer} class passed to the newBuilder * method represents one * server, conveying its host and port number, which the ACC can use to * "bootstrap" into the server-side ORB(s). The calling * program can request to use secured communication to a server by also passing * an instance of the {@link Security} configuration class when it creates the TargetServer * object. Note that the caller prepares the TargetServer * array completely before passing it to one of the newConfig * factory methods. * The Builder implementation * does not override or augment the list of target servers using * system property values, property settings in the container configuration, etc. If such work * is necessary to find additional target servers the calling program should do it * and prepare the array of TargetServer objects accordingly. *

* The calling program also passes either a File or URI for the app client * archive to be run or a Class object for the main class to be run as an app client. *

* After the calling program has created a new AppClientContainer.Builder instance * it can set optional * information to control the ACC's behavior, such as *

    *
  • setting the authentication realm *
  • setting client credentials * (and optionally setting an authentication realm in which the username and password * are valid) *
  • setting the callback handler class *
  • adding one or more {@link MessageSecurityConfig} objects *
*

* Once the calling program has used the builder to configure the ACC to its liking it invokes the * builder's newContainer() method. * The return type is an AppClientContainer, and by the time * newContainer returns the AppClientContainer * has invoked the app client's main method and that method has returned to the ACC. * Any new thread the client creates or any GUI work it triggers on the AWT * dispatcher thread continues independently from the thread that called newContainer. *

* If needed, the calling program can invoke the stop method on * the AppClientContainer to shut down the ACC-provided services. * Invoking stop does not stop any * threads the client might have started. If the calling program needs to * control such threads it should do so itself, outside the AppClientContainer * API. If the calling program does not invoke stop the ACC will * clean up automatically as the JVM exits. *

* A simple case in which the calling program provides an app client JAR file and * a single TargetServer might look like this: *

* * * import org.glassfish.appclient.client.acc.AppClientContainer;
* import org.glassfish.appclient.client.acc.config.TargetServer;
*
* AppClientContainerBuilder builder = AppClientContainer.newBuilder(
*    new TargetServer("localhost", 3700));
*
* AppClientContainer acc = builder.newContainer(new File("myAC.jar").toURI());
*
*
(or, alternatively)
*
* AppClientContainer acc = builder.newContainer(MyClient.class);
*
* Then,
*
* acc.startClient(clientArgs);
* // The newContainer method returns as soon as the client's main method returns,
* // even if the client has started another thread or is using the AWT event
* // dispatcher thread *
* // At some later point, the program can synchronize with the app client in
* // a user-specified way at which point it could invoke
*
* acc.stop();
*
*
*

* Public methods on the Builder interfaces which set configuration information return the * Builder object itself. This allows the calling program to chain together * several method invocations, such as *

* * AppClientContainerBuilder builder = AppClientContainer.newBuilder(...);
* builder.clientCredentials(myUser, myPass).logger(myLogger);
