Running VBA code in an Excel Spreadsheet created by a JSP

[baxterboy]

I am trying to use a JSP to output data to an Excel spreadsheet. No problems up to here. However, havingdone this I want to execute VBA code in the spreadsheet. I am having great difficulty finding a way to do this and was hoping someone could advise me.
The code has to be executed from the webserver and not stored on client PCs as I do not wish to make users download any libraries add-ins etc.
Thanks.
