RFC destination type G, Error 503 not available

[Former Member]

Hi,

Environment: ECC 5.0 only ABAP, Oracle, Windows 2003,

When I try to test an RFC destination of type G, I am getting an error

HTTP/1.0 503 not available

The message body gives the following error,

<td>##<H2><b>503 Service not available</b></H2>

Thanks

Hi Anil,

The RFC type is G connection to an external server,

I am just giving the host name and port number in technical details,

under logon/security I have selected No Logon.

(Would you like to know the values).

I am able to telnet the server with the given port number.

Looking at the error, why is the RFC trying to invoke an J2EE engine when there is only

ABAP Stack available.

Please let me know if you want more info.

Regards,

Vishi

Hi,

If you try to call the root URL (/) on an ABAP stack and have not defined a default service then there is no service available and the HTTP 503 message is perfectly logical.

Hi,

Thanks for your response.

Could you please provide me a suggestion as to how I should do it?

Hi

Any Ideas where I am going wrong.

Unable to figure out, why the RFC is trying to look Java stack?

I need to access to access a webservice running at the given machine name and port no.

This is all the information that I have.

Thanks.

Hi Olivier,

If you try to call the root URL (/) on an ABAP stack and have not defined a 
default service then there is no service available and the HTTP 503 
message is perfectly logical.

When you say the root URL

does it imply that I am not using a path prefix.

The client tells me that to access the service, the information

required will be only the host name and service no.

How do we get a path prefix in this situation?

Please advise.

Thanks,

Hi Olivier,

Could you give some information on this problem as well.

How can we establish an RFC of type G without a path prefix?

Thanks,

Hi,

You said :

>Target Host: viwsqa08, service no: 4444,

>Path prefix left as blank

Is this the external system or the SAP server ?

It should be the external server.

If you use a browser and call http://viwsqa08:4444 do get any answer ?

As it is the case for so many questions on these forums , you did not give enough information. It is therefore impossible to guess your context and what you are really trying to do. It does not seem clear to you either...

Hi Olivier,

My apologies,

I am not properly communicating it here.

This is the external server not an SAP server.

I am trying to call a webservice at this location using an RFC of type G.

If the test connection is successful, I plan to use this RFC destination to create a

logical port.

When I use a browser, to call the URL http://viwsqa08:4444,

I get an error message saying "Server rejected your request!".

When I convey this to the client who has given us this URL, the response was that

you cannot directly access it using a browser.

This is an error that I found in dev_rfc.trc file, will this have an impact on the

functioning of an RFC..

I am able to telnet the port, the port is being used by gwrd.exe, which I believe is the gateway server

There is an entry made in the services file

Hi,

You need to know the external web service URL, which will not be the root URL, and configure it in SM59.
