Hi, I originally had a issue trying to send a SOAP message/request but have now solved that issue. (http://www.b4x.com/android/forum/threads/help-with-soap-in-b4j.55088/) Now when I send the request I am getting a error and the reply I am getting is as below: Code: <?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><soap:Fault><soap:Code><soap:Value>soap:Receiver</soap:Value></soap:Code><soap:Reason><soap:Text xml:lang="en">Server was unable to process request. ---> Data at the root level is invalid. Line 1, position 1.</soap:Text></soap:Reason><soap:Detail /></soap:Fault></soap:Body></soap:... Internal Server Error Can't seem to work out where Line 1, Position 1 is? The code I am using to send the request is as follows: Code: 'Non-UI application (console / server application)#Region Project Attributes #CommandLineArgs: #MergeLibraries: True#End RegionSub Process_Globals End SubSub AppStart (Args() As String) Dim job1 As HttpJob Dim requestSoapXML As String requestSoapXML = "<?xml version='1.0' encoding='utf-8'?>" & _ "<soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'>" & _ " <soap:Header>" & _ " <CredentialsHeader xmlns='https://xxx.xxx.xxx.xxx/test/API'>" & _ " <OrganizationID>1234</OrganizationID>" & _ " <Username>Admin</Username>" & _ " <Password>1234</Password>" & _ " </CredentialsHeader>" & _ " </soap:Header>" & _ " <soap:Body>" & _ " <ListAccounts xmlns='https://xxx.xxx.xxx.xxx/test/API' />" & _ " </soap:Body>" & _ "</soap:Envelope>" job1.Initialize("JOB1", Me) job1.PostString("https://xxx.xxx.xxx.xxx/Accounts.asmx", requestSoapXML) StartMessageLoop End SubPublic Sub JobDone (Job As HttpJob) If Job.Success = True Then Log(Job.GetString) End If Job.ReleaseEnd Sub I do have the code working in VB.net but want to port it over to B4J since I have most of my other code working already in B4J, but if I can't solve the issue then I am going to have to port my B4J code to VB.net and give up with B4J and continue with VB.net. I can't post my VB.net code in the forum but willing to send a PM to anyone that wants to help (serious people only please) Anyone know where the error is happening ?
