Or wait till 1.5 ;)

*Neal Gafter*: Then there's autoboxing/unboxing and varargs. Boxing 
allows you to use a primitive int instead of a |java.lang.Integer|, and 
unboxing does the reverse. varargs allows you to declare a method that 
takes a variable number of arguments, which are automatically packed up 
into an array before being passed to the method.

You can make your parms Object []
This way you can pass as many params as you want.
Of course you will need to keep track of what element is what.
Maybe Java 1.5 will have the feature you are looking for :-)

sorry, dude, but param arguments are evaluated at compile time.  The
   

best
 

you could do is overload the method.

Hey as I've been building my actions I was thinking it could be useful
   

for
 

me to have a method that does some database querying, but I would like
   

to
 

give the user the ability to narrow down that query with as many input
fields as he needs.  Is there a way to write a method that takes a
   

non-set
 

amount of arguments?  (Other than just passing the method a growable
array..
which is a viable alternative)
Ie

public String myfunction(String a, String b, String c.... on down the
   

line
 

indefinitly)

?
I thought I had seen this done somewhere somehow but I may be wrong.
Thanks!
