I had some questions/suggestions regarding the Super Dynamic Invoker (..and subsequently wsif and axis). I thought I d share them on the wsif-dev list as it seemed most appropriate to post it here (apologies if it wasn't the right place for it)
A) Is the SDI part of WSIF ? If not will be included in future releases soon ? B) On the developer list of Axis, I see there will be support for XML Infoset soon. I am assuming we are seeing this as being a good thing for Dynamic invocation using complex xsd types in some ways ?If so, will WSIF move towards using this feature in Axis when it is available ? Th reason I ask all this is that currently we have a custom web service invocation framework that we developed a few years back when there was little or no support for dynamic invocation using complex xsd types and the ones available then were a bag of spanners and very hard to work with. Besides, we also had to plug-in a WS-Security implementation to our framework and WSS4J wasn't available then. However, our implementation suffers the same limitations as the Dynamic Invoker (in the initial/current? release of WSIF) in that we generate java types using castor bindings to invoke services. In our upcoming projects a client framework for dynamically invoking services without having to explicitly generate java types from xsd's or use generated stubs is very important in our software architecture. Initially WSIF seemed like a good option but we realised soon that it suffered from : A) having to generate java types for complex xsd types. B) I believe sun licences for JMS and J2EE are too restrictive for us. C) The official, stable release of WSIF (2.0 I think) uses a vintage version of axis which doesn't include some bug fixes that we require (including a patch for Attachments that we submitted and is in Axis 1_2RC2) Our approach to using WSIF currently was to try and have a version that is perhaps WSIF Lite (by ripping off support for JMS,J2EE bindings and having only a light weight web service client infrastructure). As we were thinking about it, we came upon the Super Dynamic Invoker which seems in some ways like WSIF Lite. If our thinking regarding the SDI is right, it would be good to collaborate efforts on it to achieve more than we hope to if we went on our own, say.. It would be good to know what the core developers on wsif think about this..
