Foil 46 Gateway Support of Simple Standalone Codes

From Integration of Web and Distributed Object Technologies in a New Generation of Grande Programming Environments PDPTA Las Vegas -- June 28 1999. by Geoffrey C. Fox


1 Core capabilities allow simple wrapping of existing codes
2 Program objects is defined as an XML file e.g. my favorite physics simulation on my PC becomes: <program name="physicssimulation1"> <run domain="npac" machine="maryland" type="pc" os="nt" >c:\myprogs\a.out</run> <input button="prog1" toolbar="physics" type="htmlform" > <name>userinput</name> <field default="10" maximum="100000" >iterations</field> ............ </input> <output> ...</output> </program>
3 Gateway generates a distributed object with
  • the button prog1 in physics toolbar
  • This button generates HTML form reading parameters
  • Form input data are checked and backend code activated
  • Parameters can be accessed by running code through Gateway linked library (call getparm("iterations") etc.)
