XML-Relational SOAP Connector (after the move to the CXF) it only supports executing "Document-Literal" style web services. XML-Source SOAP Connector is using Axis as the client library supports the "JAX-RPC" and as well as "Document-Literal" style web services. As I am working to combine these both connectors into one JBoss WS (native) and using only JAX-WS. Looks like JAX-WS only supports the "doc-literal" style. A question raised by SteveH is that since Teiid is an integration engine it should support connections to legacy technologies such as JAX-RPC to meet the user needs. One option here is move the XML Connectors to the JAX-WS style, then provide another connector that can be to JBoss ESB, where user can choose to implement any kind of transport. Teiid team would like to put this on the road map irrespective of this particular need, however the question is if this will satisfy the needs of our users? Thanks. Ramesh..
