Which messages of soap call processes the block exception branch?

Question

Hi guys!
I'm testing a scenario, where I use BPM, have a block, sync web service call inside and have exception branch, which sends original message to the dest system. I'm a little bit confused, cos' I'm not sure, which error messages does exception branch process. Is it only system error? Or is it also application error - means: fault message is returned..
Thanx, Olian!

ok, If I send 0 as parameter, I get exception:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <SOAP-ENV:Body>
      <SOAP-ENV:Fault>
         <faultcode>SOAP-ENV:Client</faultcode>
         <faultstring>Division by zero</faultstring>
         <detail>
            <ns1:div_test.CalcException xmlns:ns1="urn:CalculatorWsd/CalculatorVi" xmlns:pns="urn:test">
               <pns:message>Division by zero</pns:message>
            </ns1:div_test.CalcException>
         </detail>
      </SOAP-ENV:Fault>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
But When I send one string parameter, I get
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <SOAP-ENV:Body>
      <SOAP-ENV:Fault>
         <faultcode>SOAP-ENV:Client</faultcode>
         <faultstring>Deserializing fails. Nested message: XML Deserialization Error. Can not create instance of [java.lang.Integer] with parameter [ee]..</faultstring>
         <detail>
            <ns1:com.sap.engine.services.webservices.additions.soaphttp.exceptions.ProcessException xmlns:ns1="http://sap-j2ee-engine/error">Deserializing fails. Nested message: XML Deserialization Error. Can not create instance of [java.lang.Integer] with parameter [ee]..</ns1:com.sap.engine.services.webservices.additions.soaphttp.exceptions.ProcessException>
         </detail>
      </SOAP-ENV:Fault>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
So, these are two possible exceptions...  How to get them? Both are two different message types
OR: hot to get detail text to send it to receiver? What steps need to be in the exception branch?
