Subject Re: Problem with xs:base64Binary
Date Thu, 07 Aug 2008 03:06:10 GMT

Hi,

I have similar requirement for develop a soap client that send base64binary. 

My use case is that i got to convert some of the sensitive info from string
into base64binary, then send it as inline content instead of attachement.

Matt, do you found the solution of:

>         // base64 data.

Thilina, in your ByteArrayDataSource example, do I need to configure
somewhere for the base64binary?

Thank you.:-D

Truly,
Thiam Teck
