Lamentably, I don't know much about visual basic and using it with SOAP but I'd be very suprised if there were not a way to do this. It might be as simple as casting your XML String to a byte[] (or whathever the visual basic equivelent is) and passing it as a parameter. On the Apache SOAP side of things, if you make the parameter byte[] then it will expect it to be base64 and do the decoding for you. Visual Basic is probably similar so in all probability, you don't need to worry about it. Here is a link to the (terse) SOAP spec on the topic:

Barnaby, Thanks a lot for your hint. The string I am passing is validated XML string, I read from somewhere that the best way is to use LITERAL_XML encodingStyle. But I don't how to write the client VB code/WSDL to use LITERAL_XML or BASE64 ? Are there any samples on using different encodingStyles?

Did you try sending it as a data base64 encoded parameter rather than a string? i.e. a parameter of xsi:type="SOAP-ENC:base64"? I would think this would be handled more efficiently than an xsi:type="xsd:string" parameter. If your class on the Apache SOAP side is byte[] it will be automagically converted to SOAP-ENC:base64.

Hi, I think that if the size of the string is too large, then you should send it as an attachment. I remember of seeing an article somewhere, which mentioned that if the string that you are sending is of a very large length, then it may not get the correct results as well. I think that I read it on this mailing list only, but cant remember it off-hand.
