Constructor Detail

JasperLoader

public JasperLoader(java.net.URL[] urls,
                    java.lang.ClassLoader parent,
                    java.security.PermissionCollection permissionCollection,
                    java.security.CodeSource codeSource)
Method Detail

loadClass

public java.lang.Class loadClass(java.lang.String name)
                          throws java.lang.ClassNotFoundException
Load the class with the specified name. This method searches for classes in the same manner as loadClass(String, boolean) with false as the second argument.

Overrides:
loadClass in class java.lang.ClassLoader
Parameters:
name - Name of the class to be loaded
Throws:
java.lang.ClassNotFoundException - if the class was not found

loadClass

public java.lang.Class loadClass(java.lang.String name,
                                 boolean resolve)
                          throws java.lang.ClassNotFoundException
Load the class with the specified name, searching using the following algorithm until it finds and returns the class. If the class cannot be found, returns ClassNotFoundException. If the class was found using the above steps, and the resolve flag is true, this method will then call resolveClass(Class) on the resulting Class object.

Overrides:
loadClass in class java.lang.ClassLoader
Parameters:
name - Name of the class to be loaded
resolve - If true then resolve the class
Throws:
java.lang.ClassNotFoundException - if the class was not found

getResourceAsStream

public java.io.InputStream getResourceAsStream(java.lang.String name)
Delegate to parent

Overrides:
getResourceAsStream in class java.lang.ClassLoader
See Also:
ClassLoader.getResourceAsStream(java.lang.String)

getPermissions

public final java.security.PermissionCollection getPermissions(java.security.CodeSource codeSource)
Get the Permissions for a CodeSource. Since this ClassLoader is only used for a JSP page in a web application context, we just return our preset PermissionCollection for the web app context.

Overrides:
getPermissions in class java.net.URLClassLoader
Parameters:
codeSource - Code source where the code was loaded from
Returns:
PermissionCollection for CodeSource
