Hello,

That's because without WSDL information, a driver cannot know the
defined type of passing parameters.  To specify its type directly at
runtime, you can use SOAP/OM layer object (SOAP::*) such as;

  def test_echoBase64_xsd_base64Binary
    log_test
    str =3D "Hello (=C6=FC=CB=DC=9E=ECJapanese) =80=B3=80=F3=80=CB=80=C1=80=
=CF"
    arg =3D SOAP::SOAPBase64.new(str)
    arg.as_xsd        # Force xsd:base64Binary instead of soap-enc:base64=

    var =3D drv.echoBase64(arg)
    assert_equal(str, var)
  end

  def test_echoBase64_SOAP_ENC_base64
    log_test
    str =3D "Hello (=C6=FC=CB=DC=9E=ECJapanese) =80=B3=80=F3=80=CB=80=C1=80=
=CF"
    arg =3D SOAP::SOAPBase64.new(str)
    var =3D drv.echoBase64(arg)
    assert_equal(str, var)
  end

(excerpted from
http://dev.ctor.org/soap4r/file/trunk/test/interopR2/client.rb)

You WSDL seems to define the parameter as xsd:base64Binary, so use the
former one.

There's also another solution.  To escape from this kind of Ruby
<-(SOAP)-> Java type mapping problem, you can let Java module to
inference its type by removing type attribute for each element, if the
Java side is utilizing a WSDL.

  drv.generate_explicit_type =3D false

As a fact, your WSDLDriver sample does it implicitly.
