I'm having an issue with Ruby code posting SOAP using Savon
I have a parameter XML_BODY which apparently is not being sent, or, if it is, looks null to the Java code receiving it (if I try to return "TEST"+XML_BODY, the response shows "TEST null")
The other data seems to be sending okay - really confused
Client operations are pub_mugs(), post(), subscribe()
This Python/Zeep code succeeds completely
from requests import Session
from zeep import Client
from zeep.transports import Transport
if __name__ == "__main__":
url="http://localhost:8080/Wormhole?wsdl"
with open('../../web/web/xsd/DETEP2012-with-content.xml', 'r') as f:
xml=f.read().replace('\n', '')
session = Session()
session.verify = False
transport = Transport(session=session)
client = Client(url, transport=transport)
print client.service.PubMugs(username='usr',password='pwd') #SUCCESS
print client.service.subscribe(username='usr',password='pwd') #SUCCESS
print client.service.post(username='usr',password='pwd',mug='110',XML_BODY=xml) #SUCCESS
This Ruby/Savon code succeeds for the pub_mugs() and subscribe(), but fails for post()
client = Savon.client(wsdl: ENV["WSDL"],
:ssl_verify_mode => :none,
:raise_errors => false,
pretty_print_xml: true)
doc = File.open("../web/web/xsd/DETEP2012-with-content.xml") { |f| Nokogiri::XML(f) }
xml = doc.to_xml.delete("\n").split(">",2)[1] # Removes initial <?xml ... >
ap xml # The XML here looks correct
response_pub_mugs = client.call(:pub_mugs, message: { username: "usr", password: "pwd" } )
ap response_pub_mugs #SUCCESS
response_subscribe = client.call(:subscribe, message: { username: "usr", password: "pwd" } )
ap response_subscribe #SUCCESS
#THIS CALL FAILS!
response_post = client.call(:post,
message: {
username: "usr",
password: "pwd",
mug: "110",
XML_BODY: xml
}
)
FAULT RESPONSE IS THIS
:fault => {
:faultcode => "S:Server",
:faultstring => "java.lang.NullPointerException",
:"@xmlns:ns4" => "http://www.w3.org/2003/05/soap-envelope"
}
The stack trace doesn't tell me much

The post() operation runs some Java code that accesses a MySQL database
Maybe Savon is generating a different header? I'm really at a loss - any help greatly appreciated
EDIT - MORE INFO
The Java prototype for post()
@WebMethod(operationName = "post")
public String post(@WebParam(name = "username") String username, @WebParam(name = "password") String password, @WebParam(name = "mug") String mug, @WebParam(name = "XML_BODY") String XML_BODY)
BTW I also tried reading the file directly into string xml, skipping the Nokogiri doc
And I've tried removing all whitespace from the string xml, and removed pretty_print
If I change the username or password, I can get this response generated by the Java code, so apparently the Java is happy until this point, and it is accessing the database alright
:post_response => {
:return => "Unknown username or password. Message NOT submitted.",
:"@xmlns:ns2" => "http://seti/"
}

THE ANSWER WAS THIS
Added :none for convert_request_keys_to
client = Savon.client(wsdl: ENV["WSDL"],
:ssl_verify_mode => :none,
:raise_errors => false,
pretty_print_xml: false,
convert_request_keys_to: :none)
Used literal strings for hash keys
response_post = client.call(:post, message: { 'username': 'usr', 'password': 'pwd', 'mug': '110', 'XML_BODY': xml })
