AW: xsp + parameters

[Nils Leßmann]

Hi,

have a look in the generated java file (search for factoriel_xsp.java),
that's usually the fastest way to see what's really going on.

Anyway, I'd suggest using a second method

public static String get_fac(String number) {
  try {
long l = Long.parseLong(number);
return fac(l);
  } catch (NumberFormatException e) {
return number+" not a number";
  }
}
 
and calling this from the xsp.

Nils

Betreff: Re: xsp + parameters


So, I've tried the following code, in the aim to convert String to long:
 result:
fac(java:lang.Long.parseLong())

but it doesn't run:
Error compiling factoriel_xsp: Line 127, column 57: ')' expected. Line
0,
column 0: 1 error

Hi,

Thanks for your response. When I do the following:


>
> Try something like:
>
> result: fac( name="number" default="0"/>)
>

I obtain such an error message:

description org.apache.cocoon.ProcessingException: Language Exception:
org.apache.cocoon.components.language.LanguageException: Error compiling
factoriel_xsp: Line 128, column 32: Incompatible type for method. Can't
convert java.lang.String to long. Line 0, column 0: 1 error

So, I've tried the following code, in the aim to convert String to long:
 result:
fac(java:lang.Long.parseLong())

but it doesn't run:
Error compiling factoriel_xsp: Line 127, column 57: ')' expected. Line 0,
column 0: 1 error

Cyril.

Try something like:

result: fac()

Hi,
 
I would like to calculate the factorial of a number via XSP. The 
number should be transmitted as a parameter via HTTP.
 
The code I've got for this purpose is the following: it retrieves the 
parameter 'number' and defines a fac method, that calculates the 
factorial of its formal parameter.
My problem: I don't know the syntax to calculate the fac() for the 
parameter 'number'. For the moment, I'm just able to calculate fac(8) 
or fac(13), and it runs well; but itsn't exactly what I want...
 





xmlns:xsp="http://apache.org/xsp";

xmlns:xsp-request="http://apache.org/xsp/request/2.0";>



public static long fac(long n) {

if (n>1) return (fac(n-1)*n);

else return 1;

}











 

result: fac(8)





 

I would be very grateful for any assistance,

Thanks,

Cyril.

xsp + parameters

Hi,
 
I would like to calculate the
