Constructor Detail

RailoClassLoader

public RailoClassLoader(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

RailoClassLoader

public RailoClassLoader(java.io.InputStream jar,
                        java.lang.ClassLoader parent,
                        boolean secure)
                 throws java.io.IOException

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.

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).

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)
