JCL is a light weight API and has only a few but useful classes. Here is a simple example on how to programmatically use JCL. JarClassLoader has an arguments-constructor and add methods that take jar-file/class-folder paths, URLs and InputStreams.

(JarClassLoader.java:141) at org.netbeans.MainImpl.execute(MainImpl.java:178) at org.netbeans.MainImpl.main(MainImpl.java:85) at org.netbeans.

import com.mordred.jarclassloader.Loader; and then use the following method. public class JARClassLoader extends java.lang.ClassLoader. This class is an implementation of the ClassLoader abstract class. Its purpose is to allow the ability to load a class from a particular JAR file without regard to the system class path.

Jarclassloader api

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. The default system class loader is an implementation-dependent instance of this class. If the system property " java.system.class.loader " is defined when this method is first invoked then the value of that property is taken to be the name of a class that will be returned as the system class loader. The JarClassLoader Class. The JarClassLoader class extends java.net.URLClassLoader.

JARClassLoader public JARClassLoader(URL url, ClassLoader parent) throws IOException Creates a new JAR class loader that loads the JAR file from the specified URL and caches all entries in memory. Parameters: url - the URL of the JAR file to load.

public JarClassLoader(byte[] pJar, java.lang.ClassLoader pParentClassLoader) throws java.io.IOException Constructor. Takes a in memory jar file and class loader parent Method Detail: addJar public void addJar(byte[] pJar) throws java.io.IOException This method will take passed in-memory jar

JarClassLoader public JarClassLoader(File jarFile, ClassLoader parent, Collection dependencyClassLoaders) throws IOException Throws: IOException; Method Detail. loadClass public Class loadClass(String name) throws ClassNotFoundException Overrides: I want to invoke a method which inside a external .jar by using reflection.

public class JARClassLoader extends java.lang.ClassLoader A class loader implementation that loads classes from JAR files. All instances share the same set of classes.

java.lang.ClassLoader. 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.

The order is not defined so the behavior might change depending on OS, Java version and Java vendor.

The JarClassLoader 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.

The JarClassLoaderclass extends jar.net.URLClassLoader, a new class in version 1.2 of the JavaTMplatform. As its name implies, URLClassLoaderis designed to be used for loading classes and resources that are accessed by searching a The URLs can refer either to directories or to JAR files. JCL is a light weight API and has only a few but useful classes. Here is a simple example on how to programmatically use JCL. JarClassLoader has an arguments-constructor and add methods that take jar-file/class-folder paths, URLs and InputStreams.

Since, I need either of the jar to be loaded at a time, I used JarClassLoader to create a proxy for adding one jar and loading its classes. But I face ClassNotFoundException. I am working with a Java library that has some nested JAR files in lib package. I have 2 issues: I cannot see referenced types in my IDE (I am using JetBrains IntelliJ) Of course I get class not Java uses ClassLoader implicitly when you use new, import keyword, the jvm will use the current class's classloader to load the dependent classes, so you can use the custom classloader to load a bootstrap class explicitly by using classloader.loadclass, and the bootstrap just runs a method belonging to your target class instance.
