PH22498: JAX-PRC WEB SERVICE CLIENT CREATION FAILS IF AN HTTP REDIRECT SWITCHES PROTOCOL WHEN ACCESSING THE WSDL URL.

APAR status

• Closed as program error.

Error description

• Creation of a JAX-RPC client failed when the HTTP Request
  accessing the provider's WSDL was redirected with the
  redirected URL switching protocol from HTTP to HTTPS.
  
  A typical FFDC associated with the issue is shown below:

  ****************************************************************
  When creating a Web Service client, the provider's WSDL is
  read.  If the provider's WSDL is accessed via the HTTP
  Protocol then a redirection may occur, instructing the client
  to access a different URL.  By default, this redirection will
  occur only if the protocol, for example HTTP or HTTPS, does
  not change.  If the redirected URL has a different protocol
  then the redirection fails.  This default behaviour comes from
  the use of the JRE's java.net.* classes themselves and is
  deliberate since switching protocols with no warning to the
  user could represent a security issue.
  

Problem conclusion

• Retrieval of a Web Service provider's WSDL can be configured to
  automatically follow HTTP redirects that switch protocol to
  HTTPS by configuring the JVM system property
  com.ibm.wsdl.followRedirects to a value of true.  The default
  behaviour remains unchanged.
  
  The fix for this APAR is targeted for inclusion in fix packs
  8.5.5.18 and 9.0.5.5. For more information, see 'Recommended
