How to create Web Service from WSDL in ESB 4.9

[hskruse]

Hi,

I am somewhat new to the ESB world and I am trying to take an existing web service from it's WSDL and create a web service on the ESB.  What are my options?  Can't I just use the existing WSDL/XSD's I have to generate a web service on the ESB?  I hope I am making this harder than it should be.

Thansk,

Steve

Steve,

You can extract the request, response and fault schemas from your existing WSDL and then can host them as a WebService in ESB. Checkout the publish_as_webservice quickstart. Of course you will have to write the Action classes to handle these SOAP messages.

Are you sure you don't need to use the ESB only as a proxy for webservices? This is a common usage of ESB with alredy defined webservices.

There are many ESB out of the box actions for webservices, have a look at them (SoapClient,SoapProxy,SoapProcessor)

Right... maybe provide a few more details.  You may want:

1. What Magesh is referring to if you want to manually process the SOAP payload in an ESB action, or
2. The SOAPProxy if you are proxying a WS call through the ESB to a target Webservice endpoint, or
3. To implement a JSR181 Webservice (bundled into your ESB for deployment) that uses the ServiceInvoker to invoke your WS enpoint.  This approach gives you full control over jax-ws handlers etc, if that's what you need.

Prob more options, but depends on what you're doing.
