Appl. No.:

09/359612

Inventors:

Viktors Berstis - Austin TX, US
Janet Dmitrovich - Round Rock TX, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F017/30

US Classification:

707 10, 707501, 707102, 709217

Abstract:

Transitions between current and succeeding World Wide Web (Web) pages are provided which are aesthetically desirable, make the user comfortable and may be easily variable by both designers and users of Web pages in computer managed communication networks such as the Web. There are provided control tags, in a transmitted page selected to succeed a currently displayed page, for controlling display functions in said currently displayed page in combination with means responsive to these control tags for implementing said display functions. In the implementation, control tags in the current page are selectively activatable in response to control tags in the succeeding page. In accordance with a preferred aspect of the invention, the current page further includes data for selectively determining whether the current page is controllable by said succeeding page. This data my be a list of URLs (Uniform Resource Linkages) of succeeding pages only by which the current page may be controlled. Conversely, the succeeding page may be set up to include this data for selectively determining whether said current page is controllable by said succeeding page.

Abstract:

A system and method are provided to allow demand loading and discarding of Java executable image (JXE) files. The virtual machine allocates an address space for a requested JXE program. The read-only portion of the JXE file is memory mapped from its nonvolatile location to the allocated memory space using read-only mapping and the read/write section of the JXE file are loaded into memory. When a page of the JXE program is needed, a page fault occurs if the read-only portion has not been loaded into memory. The operating system's page fault handler retrieves the needed page(s) from the nonvolatile storage location based upon the mapping data that resulted from the previously performed memory mapping. Because the read-only section of the JXE file is memory mapped using read-only mapping, the operating system's paging process is free to discard previously loaded memory pages that contain read-only portions of the JXE file.

Abstract:

Progressions between current and succeeding World Wide Web (Web) pages are provided which are user friendly and may be easily variable by both designers and users of Web pages in computer managed communication networks such as the Web. There are provided control tags, in a transmitted page selected to succeed a currently displayed page, for controlling display functions in said currently displayed page in combination with means responsive to these control tags for implementing said display functions. In the implementation, control tags in the current page are selectively activatable in response to control tags in the succeeding page. In accordance with a preferred aspect of the invention, the current page further includes data for selectively determining whether the current page is controllable by said succeeding page. This data my be a list of URLs (Uniform Resource Linkages) of succeeding pages only by which the current page may be controlled. Conversely, the succeeding page may be set up to include this data for selectively determining whether said current page is controllable by said succeeding page.
