How to expose mysql data as a soap web service in Talend

I want to expose data in a mysql data source as a soap web service using Talend. How can I achieve that. Please advice.

The most powerful way to do so to do so is probably to build a WSDL using Talend Open ESB Studio (Tutorial)

Alternatively, if you don't like to use another piece of software or you prefer a quick-and-dirty solution, you can achieve this with standard Talend Open Studio for Data Integration. You just need to draw a standard Talend job which redirects your mysql data output to a tBufferOutput instance. Then, you must export your job as Axis webservice, finally deploy it in your application server (Tutorial). This way, your buffer data will be automatically exposed via web service. But it has a drawback: you cannot tune the response (ie, add labels to fields or refactor the SOAP response structure at all).
