Exception occurred in communication framework: HTTP connection refused while abap proxy generation

PavanKumar — Wed, 06 Jun 2018 05:23:13 GMT

Hello All,

Working on scenario Abap proxy (SOAP) to AS2 (sync) getting below exception while creating proxy in sproxy tcode.

Exception occurred in communication framework: Error in http framework404 connection refused http://www.w3.org/2001/xml.xsd

Client has provided few xsds referenced these xsds in the ESR where xml.xsd is one of the xsd got an error related to this

Please suggest.

Note: Worked for other different scenario where i supposed to create consumer proxy without PI. So consumed the xsds provided by client then i got the same error but after importing the SSL certificates same issue got resolved.

But here in my case i.e., http://www.w3.org/2001/xml.xsd this is not an client application end point url and that toit is doesn't contain any certificate as it is http URL.

Regards

Pavan

Hi Vivek,

yes RFCs are fine.There are many proxy interfaces which are working fine.So,assuming issue with the xsd.

Hi Pavan,

Is this ABAP system in the Internet?

If you create an HTTP destination pointing to http://www.w3.org/2001/xml.xsd or https://www.w3.org/2001/xml.xsd, is it going through connectivity test?

Best regards,
Tom

No Tom, I can see this url http://www.w3.org/2001/xml.xsd in one of my xsd but not in import tag.

Please refer my attached my xsd(which contains two methods (request, response) i have imported all the reference xsds and given reference in ESR and created sync service interfaces later tried generating proxy using Sproxy t-code.

My interface is Proxy-to-AS2 (sync)

Then Getting that error. Please suggest

Regards

Any idea on this

As you have created sync service interface, for the request and response are you using the XSD or custom created Message type ?

Hi Manoj,

Thanks for your reply, I am using xsd for request and response.

I have also attached xsd in my previous comment. Please check

in ur XSD can try removing this : xmlns="http://www.w3.org/2001/XMLSchema" or replace with your local namespace and then try to generate proxy.

Hi,

When i replaced with local namespace getting below exception, FYI There are reference xsds as well in that xsd should i have remove any thing from that references?

Hi Manoj,

FYI,Worked for other different scenario where i supposed to create consumer proxy without PI. So consumed the xsds provided by client then i got the same error but after importing the SSL certificates same issue got resolved.

But here in my case consumed the xsds in PI and tried generating proxy but i.e., http://www.w3.org/2001/xml.xsd this is not an client application end point url and that to it is doesn't contain any certificate as it is http URL
