in reply to SOAP::Lite and SOAP-ENV

I've had the same problem, and this was my solution:
    # It turns out that the SOAP-ENV and SOAP-ENC tags used by default
    # by SOAP::Lite are not agreeing with the customer's
    # API. That needs soapenv and soapenc tags. Therefore, we now will
    # fiddle with SOAP::Lite's constants. Isn't life great?
    $SOAP::Constants::PREFIX_ENV = "soapenv";
    $SOAP::Constants::PREFIX_ENC = "soapenc";

    my $soap = SOAP::Lite
      ->uri(SOAP_URL)
    ....
and later on:
    # We've fiddled with SOAP::Lite's constants. As mod_perl might
    # keep these constants, we'd better be sure and change them back
    # before anyone else notices the changes... I've got a t-shirt at
    # home which says "I love SOAP::Lite", but I'm afraid to wear it.
    $SOAP::Constants::PREFIX_ENV = "SOAP-ENV";
    $SOAP::Constants::PREFIX_ENC = "SOAP-ENC";
