摘要:
A method, system, and computer-readable code for dynamically determining the most appropriate location for applying style sheets. The style sheets may be applied on a server (and/or Web proxy), or on a client, or when multiple style sheets are to be applied, some may be applied at the server while others are applied at the client. Application at the client depends on the capabilities of the client device. If the client device cannot apply style sheets, then they are applied at the server, and the resulting document is sent to the client; otherwise, the document may be sent to the client, where the client will perform the application process. Optionally, the document may be trimmed before it is sent to the client, using a style sheet preprocessing technique. General-purpose style sheets may be leveraged advantageously where a device-specific style sheet is not available, increasing the applicability of such style sheets. The style sheets may be encoded in Extensible Stylesheet Language (XSL), Document Style Semantics and Specification Language (DSSSL), or any other style sheet language having equivalent semantics.
摘要:
A method, system, and computer-readable code for retrieving style sheets from a directory or other repository, based upon partial characteristic matching. Characteristics are associated with style sheets, and retrieval is accomplished by specifying a pattern which includes one or more of the characteristics. Preferably, the style sheet characteristics are stored as LDAP (Lightweight Directory Access Protocol) objects in an LDAP directory. The style sheets may be encoded in Extensible Stylesheet Language (XSL), Document Style Semantics and Specification Language (DSSSL), or any other style sheet language having equivalent semantics.

Embodiments of the present invention address deficiencies of the art in respect to progress indication and provide a method, system and computer program product for intelligent progress indication for script processing. In one embodiment, a progress indication data processing system can be provided. The system can include a script execution engine such as an ANT configured script execution engine, a history table, and a smart progress indicator coupled to the history table. The indicator can include program code enabled to compute an expected duration of execution of a script such as an ANT script by the script execution engine based upon measured observed durations of execution for annotated portions of the script, for instance, both for the current execution and for previous successful executions.
摘要:
A method, system, and computer program product for selectively encrypting one or more elements of a document using style sheet processing. Disclosed is a policy-driven augmented style sheet processor (e.g. an Extensible Stylesheet Language, or “XSL”, processor) that creates a selectively-encrypted document (e.g. an Extensible Markup Language, or “XML”, document) carrying key-distribution material, such that by using an augmented document processor (e.g. an augmented XML processing engine), an agent can recover only the information elements for which it is authorized. The Document Type Definition (DTD) or schema associated with a document is modified, such that the DTD or schema specifies a reference to stored security policy to be applied to document elements. Each document element may specify a different security policy, such that the different elements of a single document can be encrypted differently (and, some elements may remain unencrypted). The key distribution material enables a document to be encrypted for decryption by an audience that is unknown at the time of document creation, and enables access to the distinct elements of a single encrypted document to be controlled for multiple users and/or groups of users. In this manner, group collaboration is improved by giving more people easier access to information for which they are authorized, while protecting sensitive data from unauthorized agents. A key recovery technique is also defined, whereby the entire document can be decrypted by an authorized agent regardless of how the different elements were originally encrypted and the access protections which were applied to those elements.

摘要:
An apparatus and method for enabling composite style sheet application to multi-part electronic documents is provided. The apparatus and method identify content of a requested electronic document and determine subset style sheets that correspond to the identified content. Certain ones of these subset style sheets are selected based on, for example, requesting device characteristics, for use in generating a composite style sheet. The selected subset style sheets are then merged with a global style sheet to generate a composite style sheet that may be applied to the electronic document for proper presentation on a requesting device.
摘要:
Techniques are disclosed for incrementally rendering content in a content framework (such as a portal page provided by a portal system). Upon receiving a request for a portal page, a portal server immediately returns a response including the results from portlets which have acquired their content. If some portlets have not yet finished, subsequent content is delivered at a later time through use of one of several alternative programmatically-generated mechanisms. Capabilities of existing browsers are leveraged for several embodiments, including use of refresh headers, multipart MIME (“Multi-purpose Internet Mail Extensions”) types, and portal pages structured using frames.
摘要:
The present invention provides an apparatus and method for accessing request header information used to transcode servlet output. The apparatus and method of the present invention includes a preamble that stores request header information from a request sent by a client device. The request header information is then provided to the transcoder along with the generated content data. The transcoder then performs appropriate transcoding on the generated content data based on the request header information supplied by the preamble. The transcoded content data is then sent to the client device. In this way, the client device is able to obtain content from a much larger set of content sources than with conventional systems.
