Server.CreateObject("MSSOAP.SoapClient30") fails to create object

You need to register the dlls before you can use them. Use regsvr32 <dllname> in DOS Command.

by: Olaf_DoschkePosted on 2009-04-15 at 03:35:00ID: 24146394

Well, installation of the Soap Toolkit should have done registration. Did you use the Toolkit coming with VFP8? It's a known bug of that CD, that it's installation fails, they put a broken version on VFP8 CDs. You'll need to download Soap Toolkit from MS Download then and I suggest doing that even though manually registering the DLLs might work.

Another reason might be 8insuffiient IIS rights on OLE classes or the MsSoap directory. Of course OLE needs access to that DLLs to be able to instaciate a class.

Bye, Olaf.

What are those libraries I need to register manually?

by: CaptainCyrilPosted on 2009-04-20 at 00:59:15ID: 24182594

The dlls above and vfpx*.dll where x is the version of the VFP you are using. They are found in Program Files\Common Files\Microsoft Shared\VFP.

this is ASP, Cyril, it has nothing to do with foxpro runtimes. It's all about the MsSoap DLLs. But Soap Toolkit installation should take care of registering these DLLs. The thing to know is that the system user of the IIS Webserver Service has limited rights. EG it may not be able to even just read access the soap dlls, no matter if they are registered or not.

Bye, Olaf.

Yes I agree with your point.
Please suggest me where can I check the permissions on IIS. On which Tab which oprion should be enabled/checked?

by: Olaf_DoschkePosted on 2009-04-22 at 11:09:00ID: 24207784

Filesystem rights on the MsSoap Folder to the IIS system user. No configuration in IIS, grant access to C:\Program Files\Common Files\MSSoap\Binaries within Windows Explorer.

Bye, Olaf.

I have following permissions on Directory:
C:\Program Files (x86)\Common Files\MSSoap\Binaries

Administrator: Full Control
Creator Owner: Special Permissions
Power Users: Modify, Read & Execute, List Folder content, Read, Write.
SYSTEM: Full Control
Terminal Server User: Modify, Read & Execute, List Folder content, Read, Write.
Users: Read & Execute, List Folder content, Read.

by: Olaf_DoschkePosted on 2009-04-22 at 23:47:39ID: 24212290

SYSTEM is not the system user of IIS. SYSTEM is one of many system users. IIS runs as IUSR_<<computername>>.
See here: http://msdn.microsoft.com/en-us/library/ms955939.aspx

So indee the IIS user has no permissions on this directory and that might simply be the reason it can't instanciate MSSoap OLE classes.

Bye, Olaf.

Thanks,
My Computer name is QMX-SIXSIGMA and guest user account is IUSR_SDIWEB-STG2.

My path of Soap libraries is
C:\Program Files (x86)\Common Files\MSSoap\Binaries
Why (X86) in above path?
OS is Server 2003.

by: Olaf_DoschkePosted on 2009-04-23 at 13:59:52ID: 24219750

(x86), because you most probably run a 64 bit edition of Windows 2003 and there you can have both 32 bi (x86) and 64 bit programs. MSSoap Toolkit surely is 32 bit software, but that won't matter.

IUSR_QMX-SIXSIGMA would be the standard, but that can be overridden. If, as you say IIS runs as IUSR_SDIWEB-STG2, then add IUSR_SDIWEB-STG2 to the users and grant read and execution rights for the MsSoap folders.

Bye, Olaf.

by: pankajghargePosted on 2009-04-23 at 22:39:47ID: 24221985

I have granted the full rights on following directory where MSSOAP30.dll and WISC30.dll resides.
C:\Program Files (x86)\Common Files\MSSoap\Binaries.
I have added rights for QMX-SIXSIGMA\IUSR_SDIWEB-STG2.
No Luck this time too....

How's authentication of webapp users of that asp script configured? Does IIS impersonate the client user? In that case it would perhaps be the easiest to grant access to everyone on these dlls.

What error do you get at all? Have you looked for more informations about the error in the windows event log?

Is this relevant? http://support.microsoft.com/kb/266621/en-us

I'd check permissions on the keys HKEY_CLASSES_ROOT\Interface and HKEY_CLASSES_ROOT\TypeLib anyway.

Bye, Olaf.

I have tried the code in .vbs file. It gives me error as: ActiveX component can't create object: 'MSSOAP.SoapClient30' . I guess IIS has nothing to do with this error.

by: JiriZPosted on 2009-06-30 at 06:28:48ID: 24745034

Hi, I'v got similar problem.
ActiveX component can't create object.
But I'v tried the code in VBS and that was correct.
I'v seted rights for IUSR and IIS_IUSRS on "c:\Program Files (x86)\Common Files\MSSoap\Binaries" but nothing.
I guess I have to set rights somewhere else yet.
Don't you know where?
Thanx

Hi JiriZ,

Finally I have accessed the web service by sending the web request as a plain XML text. In response I got the XML which I am loading in XML DOM as follows.
You just need to type the webservice in browser and click the method you want to access from web service. After you click you will get all header information that you have to pass as a plain XML. I am accessing Authentication through web service so I have to pass the 'User Name' and 'Password'.

I guess this will help you.
