Package wt.security

The wt.security package gets jarred into wt/security/security.jar, which is signed so that this package may be used within a security manager, namely the Applet sandbox, to perform operations which are not typically allowed to non-signed code. Each of the Access subclasses wrap a java.XXX api to give applets access to these operations. Use the getXXXAccess factory method to retrieve an Access instance to perform these calls. For example, FileAccess.getFileInputStream() wraps java.io.FileInputStream to give applets the ability to read files on the local system. Additional prompts are displayed to the user for each of these types of operations (the grant/deny dialog you see when trying to upload/download content) per codebase, so that a "rogue" system can not get a copy of the security.jar and perform out-of-the-sandbox operations silently.
