Definitions

  • the present invention relates to the field of data exchange; more particularly, the present invention relates to exchanging data between two programming environments, such as, for example, HTML and Java.
  • Exchange systems provide the mechanism by which information may be passed between two distinct programming environments. In other words, such exchange systems allows information that is in a form for use with one type of program to be accessible through another type of program.
  • the exchange systems are based on hardcoding of one type of programming in another.
  • one prior art exchange system hardcoded HTML text in a Java program and output it to the user's browser.
  • the output of HTML may be hardcoded in a Java servlet.
  • another prior art exchange system such as JSP, hardcoded Java programming inside an HTML page to enable the exchange of information.
  • the hardcoding essentially ties the two different types of coding together, thereby causing problems.
  • JSP if a change is desired in the Java code, the HTML environment must be used. If an individual does not want to use the HTML environment, they cannot duplicate the code and make the desired changes.
  • Hardcoding in the prior art is also limiting when multiple natural speaking languages are to be supported for particular content over the Internet.
  • to support multiple natural speaking languages separate and distinct web pages had to be created and stored for each distinct language. If a change to the content is to be made, then all the web pages having that content for each separate language had to be corrected. Making changes to a large number of pages increased the chance that an error is made in one or more of the pages. What is needed is a way of supporting multiple natural speaking languages while reducing the chance or affect of such errors when changes are necessary.
  • a method comprises receiving a markup language template from a markup language execution environment, the template specifying data, executing one or more functions to cause access to information in a data using routines of another programming language environment, creating a table to associate at least one variable from the markup language execution environment with the data from the programming language environment, and merging data in the table with the markup language template to create a markup language document.

  • Figure 3 is a block diagram of one embodiment of a network environment.
  • Figure 4 is a block diagram of an exemplary computer system.
  • An exchange system is described. Such an exchange system may be used to support multiple markup languages (e.g., HTML, WML, HDML, etc.), multiple natural languages (e.g., English, French, Chinese, etc.), multiple user interaction flows (such as, e.g., various clicks on a web site, various button presses on a WAP phone, etc.), all of which may be based on a common underlying server (e.g., a Java server).

  • the present invention also relates to apparatus for performing the operations herein.
  • This apparatus may be specially constructed for the required purposes, or it may comprise a general purpose computer selectively activated or reconfigured by a computer program stored in the computer.
  • a computer program may be stored in a computer readable storage medium, such as, but is not limited to, any type of disk including floppy disks, optical disks, CD-ROMs, and magnetic-optical disks, read-only memories (ROMs), random access memories (RAMs), EPROMs, EEPROMs, magnetic or optical cards, or any type of media suitable for storing electronic instructions, and each coupled to a computer system bus.
  • a machine-readable medium includes any mechanism for storing or transmitting information in a form readable by a machine (e.g., a computer).
  • a machine-readable medium includes read only memory ("ROM”); random access memory (“RAM”); magnetic disk storage media; optical storage media; flash memory devices; electrical, optical, acoustical or other form of propagated signals (e.g., carrier waves, infrared signals, digital signals, etc.); etc.
  • An exchange mechanism is provided to exchange information between a markup language execution environment and a Java programming execution environment, where "environment" refers to the programming language utilized therein.
  • the markup language may be an HTML, WML or another markup language.
  • the exchange mechanism translates variables that are in an HTML, WML, or other markup language into information that may be processed using Java and vice versa.
  • the exchange mechanism is implemented in XML.
  • a benefit of such an approach is that coding done in the HTML environment may operate independent of the programming in the Java environment (as well as the exchange environment) apart from an interface thereto.
  • the HTML environment includes multiple HTML templates.
  • Each HTML template contains text or other data that may be substituted from the Java environment through the exchange mechanism.
  • a complete HTML web page may, in turn, contain multiple templates that are substituted into the web page through the exchange mechanism.
  • a web page may be constructed in a modular fashion, thereby simplifying the creation and modification of a web site.
  • the dynamic data is obtained from a database via the exchange mechanism.
  • the exchange mechanism translates the database information into a table.
  • the table maintains a reference to allow access to the Java content that was requested by the HTML environment by associating a variable in the HTML environment with the actual data in the Java environment.
  • the table provides a reference between the information in Java objects and a specific substantiation of an HTML template. In this manner, using variables in the HTML environment may be substituted for real values from the Java environment and a relationship is maintained between the substituted text in the HTML document and its representation in the Java environment.
  • the exchange mechanism operates using software that provides a set of functions to access Java content and allow building up the table.
  • the functions define the method by which the data from the database is accessed and stored in the table.
  • the table is a key value table that may be based on property values that are well known in the art for use in Java programming.
  • the key value table associates a key word with its specific data (e.g., the key being "phone number” and the value being the actual number itself).
  • the exchange mechanism uses a display function to cause the merge operation to occur.
  • a function executed by the exchange mechanism is a comparison operation that compares data and selects certain data for entry in the table based on the outcome of the comparison.
  • an HTML page may be displayed as a response of the exchange mechanism.
  • the individual By entering information on the web page associated with one of the web page templates, the individual causes a request to be made to the exchange mechanism, specifying variables that are inputs to the request.
  • the exchange mechanism transfers those variables to the Java environment according to the exchange definition being used.
  • the exchange mechanism also executes the underlying Java functionality specified in the exchange definition. The result of the execution is transferred from the Java environment and used by the exchange mechanism to construct a new web page as a response.
  • the exchange mechanism handles a request based on the exchange definition that may take the input information from the HTML ⁇ page and store it in the table. Then the exchange mechanism calls functions to assign the information correctly into the database.
  • the HTML page need only indicate what functions to call to obtain a particular piece of data and assign a variable to it. For example, if the HTML page provides a paging number, then the HTML page need only add an assignment statement assigning the paging number to a variable recognized and used by an exchange definition in the exchange mechanism. If a voice number is to be added, the HTML need only add another assign statement to cause another variable to be assigned.
  • HTML programmer is allowed to change the flow of what data appears on web pages.
  • an individual HTML template may be set up with a variety of references and each of the references are linked to executable Java routines, the selection of which information to put in the template essentially controls the flow of information to a user in the HTML environment.

  • exchange mechanism 102 includes a submit function that is responsive to submission of one instantiation of the HTML template.
  • the exchange mechanism may include the following:
  • exchange mechanism 102 When the user in the HTML environment specifies content, these response operations used by exchange mechanism 102 translate the request into a request for a Java variable to assign to a specific instance of HTML content.
  • the submit function performed by the exchange mechanism 102 invokes the translation between the HTML environment and the Java environment.
  • exchange mechanism 102 In response to a substitute request by the HTML environment, exchange mechanism 102 causes the assignment of a specific Java content obtained from a database, such as database 104, via Java link 103, and the Java content is made part of a Java object with a substitute data reference.
