Thanks very much for this reply :)
However, I was wondering: will it work in a multi-threaded environment ?
I have a Servlet, where each HTTP request is handled by a separate thread, as
usual.
All those threads use the rule engine, simultaniously... if it's a static
variable, won't they override each other's data ?
Thanks again

Hi, I solved the same problem with a local variable defined in the function
tag...
To solve your proble try somthing like this...
public static double sqrtResult;
< parameter identifier="num" >
< class > Integer < / class >
< / parameter >
< java:condition >
(sqrtResult=Math.sqrt(num.intValue())) > 1000
< / java:condition >
< java:consequence >
System.out.println( sqrtResult );
< / java:consequence >
Cheers
