I tried doing the same but as far as I know, there isnt any support 
for user custom formulas. but if excel supports your 
business formulas (plugin or sumthing), then you 
can extend HSSF and write those functions using HSSF. 
Otherwise you can only write 
those functions for which excel provides support. 
Let me know if you need more help on this.
