I'd used postman to get it to work, to eliminate coding things wrong.  Once you can call it correctly, it will be easier to get it to work in whatever you are writing the program in.

The message says that it expects application/soap+xml. You send text/xml.

Change the SetrequestHeader call to set the Content-Type as server needs.

i have set like

lo_client.SetRequestHeader("Content-Type", "application/soap+xml; charset=utf-8")

but still get the same "Bad Request" response.

can you check body code. i copied this code from soupui. is it what which i should put in body ?

ls_body ='<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"; xmlns:tem="http://tempuri.org/"><soapenv:Header/><soapenv:Body><tem:GetCMSWorkQueue><!--Optional:--><tem:userName>t3</tem:userName></tem:GetCMSWorkQueue></soapenv:Body></soapenv:Envelope>'

In the SOAPUI window, the URL you have is mixed case, and your code has it in all lower (for the first portion). Request might be failing if webservice is case sensitive. It's also a different spelling.

code = wkfqueuemanager.svc

sample=WKFMSMQManager.svc
