Webservice proxy - ICM_HTTP_CONNECTION_FAILED

[LeonardoAraujo]

I've posted a thread on the ABAP development.

I think it should be here.

<a href="http://Webservice proxy - ICM_HTTP_CONNECTION_FAILED">http://Webservice proxy - ICM_HTTP_CONNECTION_FAILED</a>

Any ideas on what is going on?

Thanks

hi,

sorry I don't post to the crap forum over there.

Obviously you issued a HTTP request (e.g. a webservice) and ICM(Internet Connection Manager aka The General Webclient) could not make a connection. this can be due to numerous reasons, for instance that you do do not have a proxy configured, you do not have access to that proxy, your URL given does not exist or isn't routed by ICM or ....

Basically, goto transaction ST11 and find out what really happenend in one of the log files there.

In ICM log I get this...

Is there a simple way to PING the destination from the SAP server?

How (since I don't have access to the machine)? Is there a FM that allow me to PING a destination?

Thanks

go to transaction SM59, create an 'HTTP connection to an external Server', save it and 'Test Connection'.

This is the ABAP way of pinging a server

I know. I had tried it but I get exactly the same error. So am not sure if the problem is reaching the server or else.

Test 1

TARGET HOST: http://xxxx.xx.xx.xx

TEST RESULT: ICM_HTTP_CONNECTION_FAILED

Test 2

TARGET HOST: http://xxxx.xx.xx.xx SERVICE 80

TEST RESULT: ICM_HTTP_CONNECTION_FAILED

Thanks for far.

So, how come I am getting ICM_HTTP_CONNECTION_FAILED?

I changed to a HTTP destination instead of URL and now I get the following error:

hi leo,

I do not quiet understand.

Is the first post one showing a test from SAP/SM59 and the second post one showing a test from elsewhere?

If this is the case, then I suppose that you do not have a proxy server set up for your SAP system. go to transaction SIC,search the top menu for the proxy setup and set up a proxy server. the proxy server must of course be reachable from within the network segement where your SAP system is and of course the target system must be resolvable by your proxy server.

if this is to complicated for you to understand just consult your network gurus, it's their job to make sure that the target is reachable by your SAP system.

If you refer to the SM59 tests, I ran 2 set of tests, one specifying service 80 and another leaving it blank (What I think should still use port 80...). The results are the ones I put on the post. Additionally, on the test result screen you can click on HEADER Segment and it gives more information about the result.

Is that what you asked ?

BTW, I did a test with the code provided by Greg Wolf (from another post I found).

These 2 calls return values ok:

DATA: client TYPE REF TO if_http_client,
      html TYPE string.
****Create the HTTP client
TRY.
    CALL METHOD cl_http_client=>create_by_url
      EXPORTING
        url    = 'http://www.google.com/'
      IMPORTING
        client = client
      EXCEPTIONS
        OTHERS = 1.

    client->send( ).
    client->receive( ).

    html = client->response->get_cdata( ).
    write: / html.

    client->close( ).
  CATCH cx_root.
    WRITE: / 'HTTP Connection error'.
ENDTRY.

hi,

slowly we're coming close

the 'Gregor test' tells me that your proxy seems to be set. changing to a SM59 destination was a good idea.

The error you are facing now happens to me when the actual service is not at the called path. Calling awrong path on the target usually returns a simple 404(file not found) error which is often formatted in HTML (e.g. like <a href="http://www.kwent.com/some_non_existing_path">this</a>)

Youcan check your service from within ABAP like this:

1) load the WSDL of the webservice in your browser and find the URL of the actual service call in it

2) use Gregor's example an call this URL

=> when the path is correct and the service answers it should return you an XML content stating that your call was invalid (since you didn't supply any parameters)

=> when the path is incorrect or any other HTTP error occurs, you should have that in your response and be able to read the details

Hi all,

I face exactly the same issue.

My webservice is running on http://hostname:80/ws/service

In the LPCONFIG, I call the WebService with http://hostname/ws/service, but the in ST11 the trace returns the following:

INFO 15:35:26: SOAP Transport Binding CL_SOAP_HTTP_TPBND_ROOT

->IF_SOAP_TRANSPORT_BINDING~SEND() Message sent

INFO 15:35:26: SOAP Transport binding CL_SOAP_HTTP_TPBND_ROOT

->IF_SOAP_TRANSPORT_BINDING~RECEIVE() Try to receive message

INFO 15:35:26: SOAP HTTP Binding CL_SOAP_HTTP_TPBND_ROOT->HANDLE

STATUSCODE() Received return code 500 ( Internal Server Error )

ERROR 15:35:26: SOAP Message CL_SOAP_MESSAGE->IF_SOAP_MESSAGE

PART~INITFOR_DESERIALIZE() A SOAP Runtime Core Exception

occurred in method XP_READ_TAG of class CL_SOAP_XP at position id

1 with internal error id 112 and error text no extended error

message (SOAP_ESERVER) (fault location is 1 ).

SM59 connection works.

What did you do to get around this.
