title: OSB - JCA Adapter connection error
body: <p>when I try a flow in OEPE I get this error in my domain's log:</p>
  
  <p>"nested exception is: BINDING.JCA-11812</p>
  
  <p>Interaction Processing Error.
  Error when processing the execution of the interaction to API,[SCHEMA].[PACKAGE].[STORED_PROCEDURE]. An error has ocurred when processing the interaction to call to API,[SCHEMA].[PACKAGE].[STORED_PROCEDURE]. Cause: java.lang.NullPointerException.</p>
  
  <p>Make sure that the XML that contains parameter data fits with the XSD parameter definitions. This exception is unrecoverable, probably because of a modelling error."</p>
  
  <p>(NOTE: My OSB is in Spanish. I translated this)</p>
  
  <p>I'm making a flow that receives a SOAP message (HTTP), and sends parameter data to a Stored Procedure in a database. I created a JCA Adapter with JDeveloper to reference the database in my office, and the stored procedure I created on it. I put the jca, wsdl, and xsd in OEPE and generated a business service.</p>
  
  <p>So, I have 2 flows, one that receives the SOAP and from the data on its attributes sets a concatenated string of those attributes which I replace on the body of the message (using soap envelope), and route it to the second flow.</p>
  
  <p>In the second flow, I just route directly to the business services that uses the JCA. Already tested it, but it doesn't connect to the database according to above's error.</p>
  
  <p>Can someone help me on this one?</p>
