public class OSGiWebappClassLoader
extends WebAppClassLoader

Extends the webappclassloader to insert the classloader provided by the osgi bundle at the same level than any other jars palced in the webappclassloader.

Field Summary

static Set<String>

JAR_WITH_SUCH_CLASS_MUST_BE_EXCLUDED when a logging framework is setup in the osgi classloaders, it can access this and register the classes that must not be found in the jar.

Constructor Summary

OSGiWebappClassLoader(ClassLoader parent, WebAppContext context, org.osgi.framework.Bundle contributor)

Method Summary

void	addClassPath(String classPath) Parse the classpath ourselves to be able to filter things.
static void	addClassThatIdentifiesAJarThatMustBeRejected(Class<?> zclass)
static void	addClassThatIdentifiesAJarThatMustBeRejected(String zclassName)
protected Class<?>	findClass(String name)
URL	getResource(String name)
Enumeration<URL>	getResources(String name)
void	setWebappContext(WebAppContext webappContext) In the case of the generation of a webapp via a jetty context file we need a proper classloader to setup the app before we have the WebappContext So we place a fake one there to start with.

getResources

public Enumeration<URL> getResources(String name)
                              throws IOException

Overrides:

getResources in class WebAppClassLoader

Throws:

public URL getResource(String name)

Overrides:

findClass in class URLClassLoader

Throws:

addClassPath

public void addClassPath(String classPath)
                  throws IOException

Parse the classpath ourselves to be able to filter things. This is a derivative work of the super class

Overrides:

addClassPath in class WebAppClassLoader

Parameters:

classPath - Comma or semicolon separated path of filenames or URLs pointing to directories or jar files. Directories should end with '/'.

Throws:

IOException

setWebappContext

public void setWebappContext(WebAppContext webappContext)

In the case of the generation of a webapp via a jetty context file we need a proper classloader to setup the app before we have the WebappContext So we place a fake one there to start with. We replace it with the actual webapp context with this method. We also apply the extraclasspath there at the same time.
