How do I submit a form to a LC process using the process fields component in LC Designer

I have a PDF Form with the Process Fields component attached.<br /><br />In the FSSubmit component, I have set the URL to <br />http://localhost:8080/soap/services/SAPS_Submission?wsdl, <br />where SAPS_Submission is the name of my process.<br /><br />I open the form through a Flex app, fill out the form and press submit, but get the following error:<br /><br />  <?xml version="1.0" encoding="utf-8" ?> <br />- <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><br />- <soapenv:Body><br />- <soapenv:Fault><br />  <faultcode xmlns:ns1="http://xml.apache.org/axis/">ns1:Client.NoSOAPAction</faultcode> <br />  <faultstring>no SOAPAction header!</faultstring> <br />- <detail><br />  <ns2:hostname xmlns:ns2="http://xml.apache.org/axis/">dtross</ns2:hostname> <br />  </detail><br />  </soapenv:Fault><br />  </soapenv:Body><br />  </soapenv:Envelope><br /><br />The LC process has the schema for the form as an input variable, which is used in the execution of a insertSQLStatement.<br /><br />My knowledge of the process fields component is sketchy at best, but from what I understand, I can use it to submit to workbench without using a servlet?<br /><br />Any help with getting the data from the form to the process using this technique, or clarification about what I should actually be doing would be greatly appreciated...<br /><br />Thanks<br /><br />Ross Malan
