title: Expose Talend ETL Job as a Web Service
body: <p>I am currently evaluating Talend ETL (Talend Open Studio for Data Integration).</p>
  
  <p>I would like to know how / if i can expose an ETL Job as a Web Service. </p>
  
  <p>I know i can export jobs as web services and invoke them through a specific URL however, my goal is to be able to expose a specific WSDL with IN / OUT parameters.</p>
  
  <p>A sample use case would be:</p>
  
  <p>1) Invoke WS in Talend ETL and pass XML with data</p>
  
  <p>2) Talend ETL extracts the data from the XML and inserts them as variable(s) in the query to be executed against the DB.</p>
  
  <p>3) Talend ETL tranforms resultset from DB to XML data and responds back to the WS client.</p>
  
  <p>Finally, i would also like to know whether the same scenario can be exposed as a REST service.</p>
