Question about SOAP encoding style URI

[Hongda Lin]

Hi,
        I have a question about encoding style URI.     
        I noticed that before I use call.invoke() I need to use
call.setEncodingStyleURI("http://schemas.xmlsoap.org/soap/encoding/";);
to set the encoding style URI. Which means if I don't have access to WWW
I won't be able to use SOAP. 
        Can I not set the encoding style URI? Or can I download the xml
file from the site once and use the local file instead later?


Thanks,

Hongda Lin
