Constructor Detail

LuceeClassLoader

public LuceeClassLoader(java.io.File jarFile,
                java.lang.ClassLoader parent)
                 throws java.io.IOException

Creates a new JarClassLoader that will allow the loading of classes stored in a jar file.

Parameters:

jarFile - the name of the jar file

parent - parent class loader

Throws:

java.io.IOException

java.io.IOException - an error happened while reading the contents of the jar file

LuceeClassLoader

public LuceeClassLoader(java.io.InputStream jar,
                java.lang.ClassLoader parent,
                boolean secured)
                 throws java.io.IOException

Throws:

Method Detail

findClass

public java.lang.Class findClass(java.lang.String className)
                          throws java.lang.ClassNotFoundException

Looks among the contents of the jar file (cached in memory) and tries to find and define a class, given its name.

Overrides:

findClass in class java.lang.ClassLoader

Parameters:

className - the name of the class

Returns:

a Class object representing our class

Throws:

java.lang.ClassNotFoundException - the jar file did not contain a class named className

loadClass

public java.lang.Class loadClass(java.lang.String name)
                          throws java.lang.ClassNotFoundException

Loads the class with the specified name. This method searches for classes in the same manner as the "loadClass(String, boolean)" method. It is called by the Java virtual machine to resolve class references. Calling this method is equivalent to calling loadClass(name, false).

Overrides:

loadClass in class java.lang.ClassLoader

Parameters:

name - the name of the class

Returns:

the resulting Class object

Throws:

java.lang.ClassNotFoundException - if the class was not found

getResourceAsStream

public java.io.InputStream getResourceAsStream(java.lang.String name)

Overrides:

getResourceAsStream in class java.lang.ClassLoader
