public JarClassLoader(URL url) { super(new URL[] { url }); this.url = url; } jar:http://www.example.com/jarfile.jar!/mypackage/myclass.class. The first line in the getMainClassName method is: URL u = new URL ("jar", "", url + "!/"); This statement constructs a new URL object representing a JAR URL, appending the !/ separator to the URL that was used in creating the JarClassLoader instance. The JarRunner application consists of two classes, JarRunner and JarClassLoader. JarRunner delegates most of the JAR-handling tasks to the JarClassLoader class. JarClassLoader extends the java.net.URLClassLoader class.

The JarClassLoader class extends java.net.URLClassLoader. As its name implies, URLClassLoader is designed to be used for loading classes and resources that are accessed by searching a set of URLs. The URLs can refer either to directories or to JAR files.

Usage example: JarClassLoader jcl = new JarClassLoader(); jcl.add("myjar.jar"); // Load JarClassLoader (Showing top 20 results out of 315) Common ways to obtain JarClassLoader; private void myMethod {J a r C l a s s L o a d e r j = new JarClassLoader() The class loader uses a workaround preserving list with failed to delete temporary files in configuration file .JarClassLoader saved in the [user.home] directory. The example configuration file location: [Win7] C:\Users\username\.JarClassLoader [WinXP] C:\Documents and Settings\username\.JarClassLoader [Unix] /export/home/username/.JarClassLoader Java.lang.ClassLoader.getResource() Method - The java.lang.ClassLoader.getResource() method finds the resource with the given name. A resource is some data (images, audio, text, etc) that can be accessed b */ class JarClassLoader extends URLClassLoader { private URL url; /** * Creates a new JarClassLoader for the specified url.

The search page; Other source code files at this package level JarClassLoader has an arguments-constructor and add methods that take jar-file/class-folder paths, URLs and InputStreams. So in order to cast/clone the objects, JclUtils class is used as shown in the example below: JarClassLoader jcl = new JarClassLoader(); jcl.add For example BeanShell uses one of these so that scripts can use plugin classes. JARClassLoader public JARClassLoader(boolean delegateFirst) Creates a class loader that will optionally delegate the finding of classes to the parent class loader by default. Since: jEdit 4.3pre6; For example: One-JAR version 0.97-rc11-20100715-0959 The major version number is 0.97, the minor version number is rc11 (release-candidate 11), built on July 15, 2010 at 9:59.

net.sf.basedb.util.JarClassLoader. public final class JarClassLoader extends ClassLoader. A class loader implementation that loads classes from JAR files. Each JAR file requires a separate instance of this class. Use the getInstance (String) method to get an existing or create a new instance for a specific JAR file.

除了继承 URLClassLoader 之外,JarClassLoader 还利用了其他两个新的与 JAR 相关的 API, java.util.jar 包和 java.net.JarURLConnection 类中的特性。在本节中,我们将详细介绍构造函数和 JarClassLoader 的两个方法。 # JarClassLoader 构造函数.

So in order to cast/clone the objects, JclUtils class is used as shown in the example below: JarClassLoader jcl = new JarClassLoader(); jcl.add("myapi-impl.jar"); //Load jar file //Create default factory JclObjectFactory factory = JclObjectFactory.getInstance(); //Create object of loaded class Object obj = factory.create(jcl,"myapi.impl.MyInterfaceImpl"); //Obtain interface reference in the current classloader MyInterface mi = JclUtils.cast(obj, MyInterface.class); //Convert the object into jar:http://www.example.com/jarfile.jar!/mypackage/myclass.class The first line in the getMainClassName method is: URL u = new URL("jar", "", url + "!/"); This statement constructs a new URL object representing a JAR URL, appending the !/ separator to the URL that was used in creating the JarClassLoader instance.
