I just want to consume external web service from ESB. Service deployed in Apache axis2 web service engine. Somebody have sample code to do this please feedback.
In short, you need to add a "Web Service" step to your process. The Sonic Workbench help has a section entitled "Specifying properties for a web service invocation step".
In addition, you might want to have a look at this whitepaper (http://www.psdn.com/library/entry.jspa?externalID=5311) and the Sonic Cook-a-long: Implementing Web Services in Sonic ESB (http://www.psdn.com/library/entry!default.jspa?externalID=5316) Both of these resources start by showing how to expose an ESB process as a Web Service, but also cover how to call a web service.
