Unexpected element tag "SOAP-ENV:Envelope" seen

[tbeboreus]

Hi,

we get this error message on every request we are trying to send via gSOAP:

Unexpected element tag "SOAP-ENV:Envelope" seen

Could anyone explain me, why i get this error?

Here is the request:

POST /sdk HTTP/1.1
Host: vmware-test.boreus.de
User-Agent: gSOAP/2.8
Content-Type: application/soap+xml; charset=utf-8; action="urn:vim25/5.0"
Content-Length: 551
Connection: close
Accept-Encoding: gzip, deflate
SOAPAction: "urn:vim25/5.0"

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope

    xmlns:SOAP-ENV="http://www.w3.org/2003/05/soap-envelope" xmlns:SOAP-ENC="http://www.w3.org/2003/05/soap-encoding"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:ns1="urn:vim25"><SOAP-ENV:Body>

<ns1:RetrieveServiceContent xsi:type="ns1:RetrieveServiceContentRequestType">

<ns1:_this xsi:type="ns1:ManagedObjectReference" type="ServiceInstance">ServiceInstance</ns1:_this>

</ns1:RetrieveServiceContent>

</SOAP-ENV:Body>

</SOAP-ENV:Envelope>

And here the answer:

I'm not really sure of the support of SOAP 1.2 vs 1.1 namespace and encodings, but your client seems to be using 1.2.  I believe the default is for soap2cpp to use 1.1, unless you specify 1.2 (with "-2" as a parameter).  Perhaps rebuilding your project with explicit 1.1 as an option will resolve the issue.

[tbeboreus]

Default is SOAP 1.2 for gSOAP in the current versions. I'll give it a try with -1 als flag.

But i have found some SOAP 1.2 Messages even here in different posts. So i didn't thought it could be the protocol version.

[stumpr · Accepted solution]

I'm not really sure if that's the reason either, but it was the first thing that came to mind.  I haven't seen that error, but I'll admit I do not do a lot of gsoap work.

[tbeboreus]

Thank you. Regenerated the source with "-1" and the communication works.

[stumpr]

Interesting.  I never ran into that before.  Do you know what version of gSoap started defaulting to v1.2 for SOAP?

[tbeboreus]

I didn't find the starting version for this bevahvior.

But here is an interessting part from the gSOAP Docs:

gSOAP supports SOAP 1.1 by default. SOAP 1.2 support is automatically  turned on when the appropriate SOAP 1.2 namespace is used, which shows  up in the namespace mapping table.

[stumpr]

Interesting.  So you made a custom namespace table with the 1.2 namespace included and it turned on 1.2 support?

[ramk2011]

anyone have idea about the supporting namespace & urn of esxi5.0?

Need help, ESX ESXi 5.0.0 build-474610, specific for some customer environements. Maybe it does not apply for the previous build VMware ESXi 5.0.0 build-469512 ???

TIA

I am facing a similar issue with ESX 5.0 host, the same peice of code used to work fine for ESX 4.1.

I'm using open source library libvirt to issue calls to ESX host and for call "ParseDescriptor and createImportSpec", I get errors like:

----------------------------

internal error HTTP response code 500 for call to 'ParseDescriptor'. Fault: ServerFaultCode -
Unexpected element tag "Envelope" seen

while parsing serialized value of type string
at line 8, column 134

while parsing SOAP body

while parsing SOAP envelope
at line 2, column 0

while parsing HTTP request for method parseDescriptor
on object of type vim.OvfManager
at line 1, column 0

-----------------------------

Do anyone have any idea how I can make it work, as library prepares custom soap messages (using libxml) and does not use any gSOAP to prepare SOAP messages.

Thanks for your support !

[dude1382]

I have been able to find the above issue; xml tags needs to be escaped.

Thanks!
