If you do not have screen, then you can install it easily from an RPM or the package file for your system. As you probably already have screen or can use an RPM, I am not going to cover the building of screen from source. Starting Linux Screen Screen is started from the command line just like any other command: You are now inside of a window within screen.

KVM/Networking There are a few different ways to allow a virtual machine access to the external network. The default virtual network configuration is known as Usermode Networking. Traffic is NATed through the host interface to the outside network. Alternately, you can configure Bridged Networking to enable external hosts to directly access services on the guest operating system. In the default configuration, the guest operating system will have access to network services, but will not be visible to other machines on the network. The guest will be able, for example, to browse the web, but will not be able to host an accessible web server. By default, the guest OS will get an IP address in the 10.0.2.0/24 address space and the host OS will be reachable at 10.0.2.2. You should be able to ssh into the host OS (at 10.0.2.2) from inside the guest OS and use scp to copy files back and forth. If this configuration is suitable for your purposes, no other configuration is required. Install the bridge-utils package:

Best practices for using the Java Native Interface The Java environment and language are safe and efficient for application development. However, some applications need to perform tasks that go beyond what can be done from within a pure-Java program, such as: Integrate with existing legacy code to avoid a rewrite.Implement functionality missing in available class libraries. The JNI lets you accomplish these tasks. With JNI, native code is free to interact with Java objects, get and set field values, and invoke methods without many of the constraints that apply to the same functions in Java code. This article covers the 10 most common coding and design errors that users of the JNI make. JNI programming pitfalls fall into two categories: Performance: The code performs the designed function but does so slowly or in a way that causes the overall program to slow down.Correctness: The code works some of the time but does not reliably provide the required function; in the worst case, it crashes or hangs. Performance pitfalls Listing 1.
