org.apache.batik.bridge.DocumentJarClassLoader
- public class DocumentJarClassLoader
- extends URLClassLoader
This ClassLoader implementation only grants permission to
connect back to the server from where the document referencing the
jar file was loaded.
A URLClassLoader extension is needed in case the user
allows linked jar files to come from a different origin than
the document referencing them.

documentCodeSource
protected CodeSource documentCodeSource
- CodeSource for the Document which referenced the Jar file
- See Also:
getPermissions(java.security.CodeSource)
DocumentJarClassLoader
public DocumentJarClassLoader(URL jarURL,
URL documentURL)
- Constructor
getPermissions
protected PermissionCollection getPermissions(CodeSource codesource)
- Returns the permissions for the given codesource object.
The implementation of this method first gets the permissions
granted by the policy, and then adds additional permissions
based on the URL of the codesource.
Then, if the documentURL passed at construction time is
not null, the permissions granted to that URL are added.
As a result, the jar file code will only be able to
connect to the server which served the document.
- Parameters:
codesource
- the codesource
- Returns:
- the permissions granted to the codesource
