[kepler-users] how to add a complex fomula on Kepler

[Karen Tang]

Hi,

I am new in Kepler and  I need to have a complicated formula in the 
workflow. The formula should take three inputs (web services' outputs), 
do a complex calculation (including exponent, logrithm) then generate a 
single value.

How can I add the formula in Kepler? Do I need to have this in a Java 
class, then do it follow steps listed in your archived message 
(http://mercury.nceas.ucsb.edu/ecoinformatics/pipermail/kepler-users/2006-March/000068.html)? 
I couldn't succeed. Can you give more detailed instructions? An example 
will be great.

My goal is to enable users(ocean scientists around the world) use 
workflows I created. I am using Windows XP.

Thanks in advance.

Karen
