  ****************************************************************
  When the workspace is located on a remote server using
  folder redirection on Windows 7 the RAR files cannot be
  found by the class loader when using the J2C tooling in
  Rational Application Developer or the External Service tools
  in WebSphere Integration Developer.
  

Problem conclusion

• The deprecated toURL() method was being used from the
  java.io.File class which was causing the file paths to be
  encoded incorrectly, which dropped the server name from the
  path.  Instead the method java.io.File.toURI().toURL() is
  now used to correct encoded the file paths.
  
  This issue is fixed in Rational Application Developer
  Version 7.5.5.5 and 8.0.4
