CLIENT_CREATE_FAILED error in the Call Adapter pipeline

Question

Hi, all.
  i think i've almost done the configuration of XI 3.0(CI + 2 DIs).
  SXI_CACHE, SLDCHECK, import of IR, ID objects ...etc. are O.K.
  But when i really run some scenarios of,
  File Adapter --> XI --> ABAP Proxy or
  ABAP Proxy --> XI --> Java Proxy, messages always got error in the "Call Adapter" pipeline of IS with the following message.
  <?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
- <!--  Call Adapter
  -->
- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="">
  <SAP:Category>XIServer</SAP:Category>
  <SAP:Code area="INTERNAL">CLIENT_CREATE_FAILED</SAP:Code>
  <SAP:P1>1</SAP:P1>
  <SAP:P2 />
  <SAP:P3 />
  <SAP:P4 />
  <SAP:AdditionalText />
  <SAP:ApplicationFaultMessage namespace="" />
  <SAP:Stack>Cannot register HTTP Client(Exception 1)</SAP:Stack>
  <SAP:Retry>M</SAP:Retry>
  </SAP:Error>
  Any advice appreciated.
  Best Regards.
