Abstract: A computer-implemented method for creating transparent object adapters for replaced classes in an multi-subsystem application is provided. The method includes determining whether an original class of the original subsystem is referenced by at least one other of the multiple subsystems in response to substituting a new subsystem for an original one. If the original class is referenced by at least one other of the multiple subsystems, a pair of corresponding classes for the original class is generated. One of the generated classes defines an object adapter class having the same name and package as the original class, the other class defining a new class. The method further includes configuring the object adapter class to export methods referenced by at least one of the other subsystems and to transform data and/or handle references to adapter objects passed as parameters or returned values.

Abstract: A method, system, and computer usable program product for document link security are provided in the illustrative embodiments. A link is created to a document stored in a data storage device accessible from a data processing system. A characteristic of the document is encrypted in the link. The link with the encrypted characteristic forms an encrypted locator. The encrypted locator may be embedded into another data, such as a page, which may be transmitted with the embedded encrypted locator. A request for the document may be received. The request may include encrypted information. The encrypted information may be the encrypted locator, the encrypted characteristic, or a combination thereof. The encrypted information is decrypted. The document is accessed using the decrypted information. The document is provided in response to the request.
