Arun,
Thanks for the reply. I was trying to access one of the (supposedly)
publicly hosted web service published in xmethods.com.
I have a new problem. Now I am trying to access another web service, which
takes int as parameter and returns a String. The snippet I am using for that
is
call.addParameter("aNumber", QNAME_TYPE_INTEGER,
ParameterMode.PARAM_MODE_IN);
Integer[] params = { new Integer(100) };
String result = (String)call.invoke(params);
But I am getting the exception as
deserialization error: deserialization error: deserialization error:
unexpected element type: expected={
http://www.w3.org/2001/XMLSchema}int,

http://www.w3.org/2001/XMLSchema}string

The message element of the WSDL looks like
<message name="NumToWords_EnglishRequest">
<part name="aNumber" type="xs:int" />
</message>
- <message name="NumToWords_EnglishResponse">
<part name="return" type="xs:string" />
</message>
What am I doing wrong now? The exception says that I am sending a String.
But I am sending an Integer. Since this is RPC, I presume we cant send the
primitive 'int' as such. Or is there a way to do that or using wrapper
Integer class is the correct way?
Thanks
Sudhir
