Abstract: A multi-layer entry field is disclosed comprising a number of layers including a base plane, a field prompt layer, a Help Prompt layer, a layer displaying the data entered, and an error message layer. The layers are displayed superimposed on one another to reduce the screen area required to display the entry-field and its associated information, making the invention especially useful for Palmtop computers.

Abstract: Systems, methods and computer program products are provided for building and displaying dynamic graphical user interfaces (GUIs) that can be updated automatically without requiring code-level modification and recompiling. In response to a request to display a particular GUI on a computer display, an Extensible Markup Language (XML) data group is selected from a plurality of XML data groups and an XML display layout is selected from a plurality of XML display layouts. The selected XML data group includes one or more aggregations of data hierarchically ordered within the selected XML data group. XML data items are hierarchically ordered within each of the aggregations of data. The selected XML display layout contains one or more areas that define respective GUI display spaces within which XML data items from the respective aggregations of data can be displayed.

Abstract: A method, system, and computer-readable code for a technique with which data having dynamically variable record formats (such as that created when a dynamic schema is used with a data repository) can be easily and efficiently accommodated, without requiring modification of the code that processes the data each time the underlying data format changes. This mechanism provides a novel way to gather data that may have had changes to its format, and create a structured representation of this data that flexibly adapts to format variations. This novel technique enables all added data fields in a record to be made available for processing and removed data fields to be omitted, without requiring advance knowledge of the added and removed fields. In the preferred embodiment, a DOM tree created from an XML representation of the source data is used by the present invention as it creates an output DOM tree. Optionally, the results of an LDAP query from an LDAP directory can be used as the source data.

Abstract: This invention relates to a method of loading Java ClassFiles on to a Java Virtual Machine. On a regular JVM the ClassFile are loaded as and when required. In this specification there is described a method of implementing an object oriented program language such as Java on a computer. The method comprises identifying a class, one of the basic building blocks of the language, which is not within the program domain, that is not loaded into the Java a Virtual Machine. Next it introduces to the program domain only the minimum components of the class which are necessary for commencing processing of the class. The class may comprise several blocks of data representing the methods of the class, since the class may only have been identified because one of the methods within the class was referenced then only the block of data representing this method is loaded into the Java Virtual Machine along with the other essential components of the class.

Abstract: A method of displaying clustered data points in detail and in context within a data set. The method includes the step of identifying one or more clustered sets of data points within a data set. The data set includes a plurality of data points. The method also includes the steps of determining a respective data range segment for each cluster of data points, where each data range segment has a boundary and a scale interval, and displaying the data points in each segment such that each segment is mutually distinguishable. Where two or more data range segments are determined, the scale interval value for one of the data range segments is modifiable to differ from one or more of the other data range segments.

Abstract: The present invention provides a system and method for displaying on a display device (20) connectable to the system a visual representation of a physical environment, such as a virtual office. The system includes display controls (30) for displaying objects in the physical environment including a data management object, one or more data objects representing data sources, and one or more output objects representing paths through which data from a data source can be presented to a user. A user-operated device (50) is connectable to the system to allow a user to interact with the objects. The system includes data receiving means (70), responsive to signals from the user-operated device (50) indicating user association of one or more data objects with the data management object, to access the data represented by the one or more associated data objects.
