[esb-issues] [JBoss JIRA] Commented: (JBESB-2672) Create SOAPProxy action

Create SOAPProxy action ----------------------- Key: JBESB-2672 URL: https://jira.jboss.org/jira/browse/JBESB-2672 Project: JBoss ESB Issue Type: Feature Request Security Level: Public(Everyone can see) Components: Web Services Affects Versions: 4.5 Reporter: David Ward Assignee: David Ward Fix For: 4.6 A WS Proxy primarily focuses on the consumption of an external WS endpoint (e.g. hosted on .NET, another external Java-based AS, LAMP) and re-publication of a WS endpoint via the ESB. The ESB sits between the ultimate consumer/client (e.g. .NET WinForm application) and the ultimate producer (e.g. RoR-hosted WS). The purpose of this intermediary is to provide an abstraction layer that solves the following problems: * Provides for more loose coupling between the client & service, they are both completely unaware of each other * The client no longer has a direct connection to the remote service's hostname/IP address * The client will see modified WSDL that changes the inbound/outbound parameters. At a minimum, the WSDL must be tweaked so that the client is pointed to the ESB's exposed endpoint instead of the original, now proxied endpoint. * A transformation of the SOAP envelope/body can be introduced via the ESB action chain both for the inbound request and outbound response * Service versioning is possible since clients can connect to 2 or more proxy endpoints on the ESB, each with its own WSDL and/or XSDs and the ESB will handle the transformation & routing requirements to send the appropriate message to the appropriate endpoint and provide an ultimate response. * Injection of things like WS-Security * Complex context-based routing Current mechanisms of doing this are inappropriate or inadequate: * SOAPClient is used to invoke external web services, not mirror them * SOAPProducer only executes internally-deployed JBoss WS services. * HttpRouter requires too much by-hand configuration * EBWS strips out the SOAP Envelop and only passes along the body With a SOAPProxy action: * it is both a producer and consumer of web services * all that is required is a property pointing to the external wsdl * wsdl can be automatically transformed via the optional wsdlTransform property * multiple transports are automagically detected and handled (only http to be initially implemented, however, but jms in future?) * if using http, any of the HttpRouter properties can also optionally be applied to as overrides
