Centralized field rendering system and method
View Patent ↗The invention includes system for centralized rendering of user interface elements based on configurations as described in XML. A developer may create a definition for a field based on the nature of the information to be displayed to a user within a single file. Such definition will affect all future instances of the particular data type without a need to modify and/or compile code residing either within an HTML file or on a server.
1. A method comprising:
retrieving, by a computing system, an Extensible Markup Language (XML) tag from a web resource in response to a request for the web resource;
matching, by the computing system, the XML tag to a tag in a data type definition (DTD) file to obtain information in the DTD file identifying a first class file for use in rendering a user interface element for the web resource;
mapping, by the computing system, the first class file within a servlet based on the obtained information;
performing a first rendering, by the computing system, of the user interface element for the web resource by executing program code in the servlet based on the first class file;
changing, by the computing system based on user input, the class file identified by the DTD file for the tag from the first class file to a second class file, wherein the DTD file is accessible using XML tags of multiple different web resources;
receiving a second request for the web resource;
matching, by the computing system, the XML tag to the tag in the DTD file to obtain information identifying the second class file; and
performing a second rendering, by the computing system, of the user interface element for the web resource for the second request by executing program code based on the second class file, wherein the second rendering uses a different format for the user interface element than the first rendering.
2. The method of claim 1 , wherein the different format is a different input format for receiving data via the user interface element.
3. The method of claim 1 , further comprising rendering multiple different web resources based on a current class file identified by the DTD file for the tag.
4. The method of claim 1 , wherein the executing the program code based on the first class file includes preventing entry of values that do not conform to the first class file.
5. The method of claim 1 , further comprising storing the DTD file using a centralized server system that is accessible to multiple application servers.
6. the method of claim 1 , wherein the first class file and the second class file are Java class files.
7. The method of claim 1 , wherein the first rendering are second rendering are further based on one or more XML parameters in the web resource.
8. A system, comprising:
one or more processors; and
one or more memories having program instructions stored thereon that are executable to perform operations comprising:
retrieving an Extensible Markup Language (XML) tag from a web resource in response to a request for the web resource;
matching the XML tag to a tag in a data type definition (DTD) file to obtain information in the DTD file identifying a first class file for use in rendering a user interface element for the web resource;
mapping the first class file within a servlet based on the obtained information;
performing a first rendering of the user interface element for the web resource by executing program code in the servlet based on the first class file;
changing, based on user input, the class file identified by the DTD file for the tag from the first class file to a second class file, wherein the DTD file is accessible using XML tags of multiple different web resources;
receiving a second request for the web resource;
matching the XML tag to the tag in the DTD file to obtain information identifying the second class file; and
performing a second rendering of the user interface element for the web resource for the second request by executing program code based on the second class file, wherein the second rendering uses a different format for the user interface element than the first rendering.
9. The system of claim 8 , wherein the different format is a different input format for receiving data via the user interface element.
10. The system of claim 8 , wherein the operations further comprise rendering multiple different web resources based on a current class file identified by the DTD file for the tag.
11. The system of claim 8 , wherein the first rendering are second rendering are further based on one or more XML parameters in the web resource.
12. A non-transitory computer-readable medium having instructions stored thereon that are executable by a computing device to perform operations comprising:
retrieving an Extensible Markup Language (XML) tag from a web resource in response to a request for the web resource;
matching the XML tag to a tag in a data type definition (DTD) file to obtain information in the DTD file identifying a first class file for use in rendering a user interface element for the web resource;
mapping the first class file within a servlet based on the obtained information;
performing a first rendering of the user interface element for the web resource by executing program code in the servlet based on the first class file;
changing, based on user input, the class file identified by the DTD file for the tag from the first class file to a second class file, wherein the DTD file is accessible using XML tags of multiple different web resources;
receiving a second request for the web resource;
matching the XML tag to the tag in the DTD file to obtain information identifying the second class file; and
performing a second rendering of the user interface element for the web resource for the second request by executing program code based on the second class file, wherein the second rendering uses a different format for the user interface element than the first rendering.
13. The non-transitory computer-readable medium of claim 12 , wherein the different format is a different input format for receiving data via the user interface element.
14. The non-transitory computer-readable medium of claim 12 , wherein the operations further comprise rendering multiple different web resources based on a current class file identified by the DTD file for the tag.
15. The non-transitory computer-readable medium of claim 12 , wherein the first rendering are second rendering are further based on one or more)ML parameters in the web resource.
