Support documents pertaining to the class loader describe programming errors or configuration issues that result in programs or classes not being found. Typically you see an error message in the stack track trace or in the browser indicating "class not found." Class loaders are part of the Java virtual machine (JVM) code and are responsible for finding and loading class files. Class loaders enable applications that are deployed on servers to access repositories of available classes and resources. Application developers and deployers must consider the location of class and resource files, and the class loaders used to access those files, to make the files available to deployed applications. Class loaders affect the packaging of applications and the runtime behavior of packaged applications of deployed applications.
