My second article for the TheServerSide is up. Like the first one I did for TSS, this one is on WSO2. The article is all about how easy WSO2 makes it to use MTOM for sending SOAP messages with binary data attached to them, as well as the advantages of using MTOM in the first place. Products like WSO2 are making it pretty painless to use SOAP and its "advanced" features like MTOM. This article explains some of that magic.
