More bean information

[dovle]

Hi everyone ,
Hope this time I will get an answer ( please ) .

I have a bean that contains an array like this :

public class X
{
        public int[] array ;

        public int[] getArray() 
        {
                return array ;
        }

        public void setArray( int[] ar) 
        {
                this.array = ar ;
        }
}

I have set this class to be serialized / deserialized with the standard 
BeanSerializer provided with the apache soap . And I have a method on a class 
deployed on the server . 
When I make the call of the method from the client , I get the following http 
Error 500 : Internal server error :
Error building response envelope : NullPOinterException . 

So please someone tell me what I am doing wrong and how should I correct this 
problem ? 

TIA ,
dovle .
