Hello all,

While calling the below web service , the response status is ok. But I am getting the error message soap_parser: XML error parsing SOAP payload on line 1: Empty document
I have enclosed the final part of the response running in debug mode. In debug mode, the response is getting printed. But it is not returned from the web service.

Can anyone help me in this regard?

Thanks in advance
Pushparaj

2006-08-22 20:38:23.954031 nusoapclient: Error: XML error parsing SOAP payload on line 1: Empty document

sure, what client read from the server is bogus data (looks like var_dump) but not a true XML payload.

Thanks . I got it

I am having the same problem when attempting to return an attachment from the server. However, it appears that the attachment is embedded in the response. Can you please explain to me how you figured out your problem?

Thanks!

Are you using any print_r, var_dump statements in stead of return statements? If so remove those and check. If not can you place the code here?

Regards
Pushparaj.

Has anyone an update to this? I am having the same problem. When I didn't have an attachment it worked fine, but once I put in an attachment I received the same error as the one above.

-Addison

did you check the XML payload the server returned when attachment was supplied?

first off thanks for the quick response, I've checked that the data is returned, here's an excerpt:



Here's some more background information:



and Sites does not include the attached document type, is that the problem?



If so how do you write into the $server->register section to take into account you are returning more than just the 'Sites" type?[/code]

I'm not familiar with what you're trying to accomplish. I did never code attachments over nusoap and therefore can hardly suggest what to do in terms of php code. But what may make good sense is to check the returned payload. Payload is whatever starts after the headers or <?xml version="1.0" encoding="ISO-8859-1"?><SOAP-ENV:Envelope... in your sample. You can save it into a file and use any XML validator available to see where the error is.

btw, I just noticed that the server responce you listed is multipart. Are you using nusoapmime? As far as I see it is the only file in nusoap package that knows of multipart.

yup here's what I'm using:

$server = new nusoapservermime;


and it works fine if I don't use attachments, it's just when attachments are put in, it goes haywire, I can see the server return the results information and the attachment but it's getting the Error



So what i'm trying to accomplish is to return two things, one is the attached document, and the other is the normal soap encoded xml data

looks like it fails to find the xml payload. What's the client code you use?
