win7 loader

1 Basic informationEach developer is certainly not unfamiliar with the Java.lang.ClassNotFoundExcetpion exception, which involves class loading in the Java technology architecture. Java's class loading mechanism is the core of the technical system, although not much directly with the majority of developers, but the mechanism behind it has a certain understanding to help troubleshoot the application of class loading failure and other technical issues, to understand the Java Virtual Machine Connec

This article focuses on the Java ClassLoader and the simple classloader that you write yourself.Several ClassLoader can be installed in a Java virtual machine, and the default ClassLoader has 3:bootstrap,extclassloader,appclassloadeR. Different classes record classes that are responsible for loading different locations. The ClassLoader itself is also a Java class, because the ClassLoader itself is loaded by the ClassLoader itself, and obviously must have the first ClassLoader, which is not a Jav

I am glad that in the company's product development process has not been caused by the boot loader resistance, because we use MSDOS+LOADCEPC to start the CE operating system. Obviously such luck is not forever, so to the boot loader should have enough research and understanding, do a rainy day. The Boot loader is an important development step in customizing the

Let's talk about parentDelegation) MechanismIn the parent delegation mechanism, each loader forms a tree structure according to the parent-child relationship. Apart from the root loader, other class loaders have only one parent loader.Assume loader2's father is loader1, and loader1's father is the system class loader. Assume that the Java program requires loader2

In the previous section, the mechanism of the system ClassLoader and the class loader is described, and the way the ClassLoader is customized. Next take Tomcat6 as an example to see how Tomat uses the self-customizing ClassLoader.

class loader working mechanismThe class loader is looking for the class's section code file and constructs the component that the class represents the object within the JVM. In Java, the class loader loads a class into the JVM, taking the following steps: [1.] Loading: Finding and Importing class files; [2.] Link: Perform the v

Class Loader DescriptionThe class loader is responsible for loading the. class file into memory and generating a Java.lang.Class instance for the class. Once a class is loaded into the JVM, the same class is not added again. The unique identity of a class in the JVM is: the class name, the package name where the class resides, and the class loader. When the JVM s

Java itself is a very simple design, very sophisticated language, so the principle behind Java is very simple, it boils down to two points:1, the memory management of the JVMUnderstanding this, all problems related to the object can be solved.2. JVM Class LoaderUnderstand this, all Java-related configuration issues, including the configuration of a variety of app servers, application publishing issues can all be resolvedAPP Class Loader|-----EJB Class

The JVM Specification defines two types of class loaders: Start the internal loader (bootstrap) and user-defined loader (user-defined class loader ). 1. Basic concepts of ClassLoader 1. ClassLoader class loaders are used to load classes into JVM. The JVM Specification defines two types of class loaders: Start the internal loa
