step 534 the feedlet 20 applies the html template to the temporary data structure the data values of the temporary data structure are substituted for tokens in the html template document in step 536 the resulting html document may be written to the specified directory the directory is typically a part of a file system of a web server system such as apache or microsoft iis referring now to fig9 a more detailed flowchart of generating the xml output feed of fig6 is shown the xml output feed is typically an xml document or file that represents the content of the temporary data structure in step 542 the feedlet 20 loads xml transformation parameters from its configuration properties stored in memory in step 544 the feedlet 20 transforms the data in the temporary data structure into a conforming xml schema using a common library such as java architecture for xml binding jaxb in step 546 the feedlet 20 writes the transformed data to the xml document in a specified directory in step 548 the xml document may be validated to ensure that the data conforms to the xml schema the method of operation of the fuselet 40 fig1 is similar to the feedlet 20 fig1 the descriptions of the flowcharts fig2 9 generally apply to the fuselet 40 with some variations which are noted below referring again to fig3 at step 230 parameters of the fuselet 39 s execution are loaded from a parameters specification data file during start up this provides configuration on the location of the input data sources and the associated urls of their hosting web server the means of connecting to these input data sources and authentication parameters that the fuselet 40 will use as credentials.
