    How to remove all checked out files in clearcase

    This cleartool command lists all the checkout files (both from the current directory and from the entire view) searching in each directory or vob path. For each element found, it invokes the command to remove the checkout.
    # Remove ALL checked out files from view in the entire vobs
    cleartool lsco -cview -me -avobs -short | xargs cleartool unco -rm 
    # Remove ALL checked out files from the current directory on only
    cleartool lsco -cview -me -rec -short | xargs cleartool unco -rm

    This is an example on how to load a SOAP web service in order to be able to invoke its methods via JMS transport

    public MyInterface loadEndPoint() {
    	//try to load from local, if available:
    	boolean loadOK = false;

    Simple CORBA java server

    This code shows an example of simple corba server in java. A CORBA server needs a local ORB object. The server instantiates an ORB and registers its servant objects so that the ORB can find the server when it receives an invocation for it. the server is a process that instantiates one or more servant objects. Each servant implements the
    // The package containing our stubs.
    import HelloApp.*;
    // HelloServer will use the naming service.
    import org.omg.CosNaming.*;
    // The package containing special exceptions thrown by the name service.
    import org.omg.CosNaming.NamingContextPackage.*;
    // All CORBA applications need these classes.
    import org.omg.CORBA.*;
    public class HelloServer 
      public static void main(String args[])
           // Create and initialize the ORB
          ORB orb = ORB.init(args, null);
          // Create the servant and register it with the ORB
          HelloServant helloRef = new HelloServant();
          // Get the root naming context
        org.omg.CORBA.Object objRef = 
          NamingContext ncRef = NamingContextHelper.narrow(objRef);
          // Bind the object reference in naming
          NameComponent nc = new NameComponent("Hello", "");
          NameComponent path[] = {nc};
          ncRef.rebind(path, helloRef);
          // Wait for invocations from clients
          java.lang.Object sync = new java.lang.Object();

    Simple RMI Java client

    This is a simple RMI client implementation. Here the client program obtains a stub for the registry on the server's host, then looks up the remote object's stub by name in the registry. Finally invokes the sayHello method on the remote object using the stub. Here the client invokes the method exposes by Hello remote interface. Note that if no
    package example.hello;
    import java.rmi.registry.LocateRegistry;
    import java.rmi.registry.Registry;
    public class Client {
        private Client() {}
        public static void main(String[] args) {
    	String host = (args.length < 1) ? null : args[0];
    	try {
    	    Registry registry = LocateRegistry.getRegistry(host);
    	    Hello stub = (Hello) registry.lookup("Hello");
    	    String response = stub.sayHello();
    	    System.out.println("response: " + response);
    	} catch (Exception e) {
    	    System.err.println("Client exception: " + e.toString());

    How to run methods in class marked with specific Java annotation

    The snippet shows how to invoke only methods of a class marked with specific annotation. The list of methods class (MyTest) is returned using reflection. Annotations are returned via getAnnotation() method. The method is executed via invoke() method.
    import java.lang.reflect.Method;
    public class MyTest {
        public void method1() {
        public void method2() {
        public void method3() {
        public static void main(String[] args) {
            MyTest runner = new MyTest();
            Method[] methods = runner.getClass().getMethods();
            for (Method method : methods) {
                MyAnnotation annos = method.getAnnotation(MyAnnotation.class);
                if (annos != null) {
                    try {

    Base class to setup the secure communication towards MailUp REST API

    This is how to setup a secure connection towards MailUP RESTful API. This base class can be extended with methods that directly call those web methods

    How to invoke the EJB remote interface - Java client application

    The codes shows how to remotely invoke the methods exposed by EJB remote interface. The client app will invoke the remote methods using a JNDI lookup. The appName and beanName refer to the remote application and ejb names to be referenced by the client app. Notice the usage of InitialContext, setting variables INITIAL_CONTEXT_FACTORY and PROVIDE
    package com.test.ejbclient;

    Safely Manage Asynchronous Invoke in Winforms

    When dealing with multithreading in WinForms one of the worst issues you encounter are the management of Invoke() method on controls. Instead of spreading the code of blocks if (control.InvokeRequired) { controlInvoke(...); } else { ... } this is a little method that can elegantly solve your issues!
    private delegate object SafeInvokeCallback(Control control, Delegate method, params object[] parameters);
    public static object SafeInvoke(this Control control, Delegate method, params object[] parameters)
        if (control == null)
            throw new ArgumentNullException("control");
        if (control.InvokeRequired)
            log.DebugFormat("Calling with BeginInvoke: {0}", method.Method.Name);
            IAsyncResult result = null;
            try { result = control.BeginInvoke(new SafeInvokeCallback(SafeInvoke), control, method, parameters); }
            catch (InvalidOperationException) { /* This control has not been created or was already (more likely) closed. */ }
            if (result != null)
                return control.EndInvoke(result);
            log.DebugFormat("Calling sync: {0}", method.Method.Name);
            if (!control.IsDisposed)
                return method.DynamicInvoke(parameters);

    Import a list of recipients through MailUp REST API

    This is an example on how to consume the API related to the import of recipients. The composed uri can be augmented with querystring parameters to better refine the criteria of import.
