I'm coming back to this after focussing on other things...
I agree with everyone that mustUnderstand checking is a core, and important (if sometimes annoying) SOAP processing rule. I also don't advocate ANYONE deploying a SOAP web services engine that doesn't do that checking. That said, I'm trying to embed Axis2 where Axis2 is not the 'whole engine' or the 'whole node'. In that case, I want to be able to insert mustUnderstand processing which 'knows' that a given set of headers are/were/will be understood outside of the scope of the Axis2 handlers/engine. Even if I were to put that login in a custom handler which runs before the engine, I'd then still incur the overhead of the AxisEngine checkMustUnderstand. This is why I'd like to move it out. Yes, there is a chance with moving it out that a user 'undeploys' the mustunderstand checking without replacing it. But, I'm happy to document (in axis2.xml) that that is a supremely bad idea and that it should only be done if you really know what you're doing. There's plenty of rope provided by axis2 to let users hang themselves... I think this is only another couple of inches. David On 23/01/07, Manoj Khangaonkar <[EMAIL PROTECTED]> wrote:
Hi David, If the mustUnderstand handler runs last, that means a node cannot ignore a header until all the handlers have executed. Until the handler executes, the node does not know if it must process the header or not. One would think that a check like mustUnderstand which is fundamental to SOAP should happen early , not late in the cycle. If mustUnderstand=true and you ignore the header, does that not make it non compliant with SOAP ? Also what if some one else comes up with a requirement that their handler needs to run last ?
