type XML conversion ...

[alemito]

Hi,
I have some problems in conversions ... I have only a method which takes an Integer and returns a Double array.
I think XML doesn't like the array concept ...

thank you all

Hi,

How your java types map to SOAP/XML types in axis.
You should use double, instead of Double.
Please refer to axis user guid for details.
