XML document in HTTP response

Hello,
I try to write a portal component, that provides an XML document. The component must be reachable via a URL. It generates an XML document from portal content. The generated XML document must be available using the URL.
I tried to solve this by implementing an AbstractPortalComponent iView. Inside the doContent method I write the XML document into the IPortalComponentResponse. The problem is, that the response does not only include the XML document, but the XML data is included inside an HTML document. I already set the EPCFLevel in component-profile to 0. So there is very few JavaScript left inside the HTML document. But I don't want any HTML at all. I want only the pure XML document inside the HTTP response.
Does anybody know a way to make a plain XML document available at an URL?
Thanks, best regards, Oliver

Try something like this in the docontent method
HttpServletResponse resp = request.getServletResponse(true);
resp.setContentType("text/xml");
resp.getOutputStream().write(bytes);

  • Adobe Document Services - http Response 500 - How to configure the logging?

    We are building an application in Web Dynpro Java that fetches data from an R/3 system via an RFC connection and is then supposed to show said data in a pdf within an iview. For that task we want to use the InteractiveForm UIElement. We bind the data to its pdfSource in the iViewu2019s context. Currently the form only consists of a text field bound to one attribute element of the pdfSource context node.
    The ADS webservice is configured according to the manuals found here:
    http://help.sap.com/saphelp_nw70/helpdata/en/fa/0b700d6cfd4e03a8ec2186ba6ff4af/frameset.htm
    and tested successfully under the following link
    http://<portal_host>:<port>/AdobeDocumentServices/Config?style=document
    However, when we execute the application, an error occurs in the webservice generating the pdf, namely Invalid Content-Type:text/html. The error occurs when the iView containing the form is shown for the first time, even before the attributes of the pdfSource context are filled with data (we expect to see an empty form).
    As it seems the webservice is expected to return a MIME type of either application/pdf or text/xml (we donu2019t know for sure since the SAP manuals and forums are inconclusive here), but instead we get text/html. This seems to be due to the fact that the webservice exits with an http response 500 Internal Server Error (we used several network monitoring tools to confirm that such a response is sent). Since such http responses are but html files with an empty body, yet not xml or pdf, the aforementioned error does make sense to us, but we do not know what Internal Error has caused it.
    The only help that SAP seems to provide for an error u201CInvalid Content-Type:text/htmlu201D in context with ADS points to an expiring password or otherwise poor configuration of the ADSUser, which (most certainly) is not our case here since, and as said above, the configuration was and can be tested successfully.
    We then tried to view the logs for this error on the machine where the J2EE engine is running with ADS installed according to this (not very comprehensible) guide:
    http://help.sap.com/saphelp_nw70/helpdata/de/97/ccfc3f0ac2c642e10000000a1550b0/frameset.htm
    We cannot find anything relevant in the server.log of the Visual Administrator except this message (it is generated exactly when our error occurs u2013 the trace severity is set to ALL for all Adobe application elements according to manual):

    There is no error.pdf to be found on the file system and since neither have we known nor are we told by the error message, whether the underlying cause is is a render error or connection error or configuration error or what not, we donu2019t know whether the error.pdf is supposed to be generated at all.
    Or could there be any other reason why generation didnu2019t take place?
    Furthermore we canu2019t seem to be able to find any logs more verbose or detailed about this issue - at least not within the Visual Administrator or the portalu2019s nwa.
    How is it possible to properly debug the webservice for pdf-generation or at least to retrieve a fully detailed log containing all notifications and exception stack traces etc.?
    I am assuming that we are making some basic mistakes regarding the logging configuration - but what?
    Our goal is to know what causes the 500 Internal Server Error response that causes the Incorrect Content-Type exception.
    We are using a NetWeaver 7.01 portal installation with Adobe Document Services 7.01 installed on a Windows Server 2003 platform.
    Any help is highly appreciated!

    Have you tried restarting the Java PDF object in Visual Administrator?  Once you do all of your config, you have to restart the PDF object (sao.com/tcwdpdfobject) for the changes to take place.  I am assuming you've run all of the test programs in SAP (FP_TEST_00, FP_TEST_03, etc.).  Is there any chance that the ADSUSER is locked somehow?

  • Receive XML document as Webservice Response

    Hi
    I have implemented webservices using axis.This works fine.
    But I need an receive the response as an XML document.because for multiple entries of same tag name, i can parse through the document and do what ever i want.
    Also how can i attach an external xsd for a wsdl.
    I am stuck up at these two places,Your help would be appriciated
    Thanks in advance

    Web service is platform independent hence most programming languages should return basic datatypes. In your case easiest thing would be to read that XSD file and convert entire file as String and return it as String. A document object will always throw an error.
    Google to find out datatypes supported.
    Hi Everyone,
    Please let me know if this can be a quick resolution to his problem.

    1. Read the Flat File using BPEL File Adapter
    2. Transform the Message in BPEL and send it to B2B
    2. Based on the set-ups in B2B, we need to post the XML message to the folliwng URL:-

    In the B2B Set-Ups, I have done the following:
    Business Protocol name: Custom Document over Internet
    Exchange Protocol: AS
    Document Protocol: Custom
    Transport Protocol: HTTP-1.1
    Host name : http://databridge.buy.datastream.net
    Port: 5555
    I have also deployed the agreement as well as the configuration. The issue that I am currently facing is when I select the configuration in WSIL browser in JDeveloper, I am getting the following error:
    "Unable to get schema information for target".
    Hence I am not able to map the message in BPEL and send it to B2B.
    Could you please let me know the possible causes and if I am missing anything in the set-ups in B2B.
    As always, your help and guidance is highly appreciated.

  • Receive HTTP response

    Hi,
    My scenario is idoc->XI-HTTP , im trying to send xml document to HTTP server. currently i'm able to send the document however i'm not able to see to response payload for the request i send. Should i go for BPM? does HTTP adapter always treat request as Asynchronous in XI. I always see the following message in trace. I dont see payload for resposne, even if there is a failure i see only the below message in trace. any help will be greatly appreciated.
    <Trace level="2" type="T">HTTP-Response :</Trace>
      <Trace level="1" type="T">Apple</Trace>
      <Trace level="2" type="T">Code : 200</Trace>
      <Trace level="2" type="T">Reason: Apple</Trace>
    Trace level="3" type="T">Async processing: skip mapping of response</Trace>
    Thanks!
    Ganesh.

    Ganesh, the default behaviour of Idoc adapter is async and therefore the communication would remain EO. For a sync scenario, you must use BPM with the following steps:
    1. Receive
    2. Transform (optional)
    3. Send sync (http)
    4. Transform (optional)
    5. Send async (idoc)
    does HTTP adapter always treat request as Asynchronous in XI.
    The type of communication depends upon sender. Http adapter can be used in both async and sync cases.
    @VJ, Abhishek, Alka - receiver does not determine the QOS of message. It is sender who determines the QOS. So there shouldn't be any such setting in http channel.

  • Send xml file over https - urgent

    Helo everybody.
    I need to solve next problem:
    1. Build/Use a client program that can operate with the HTTPS protocol. There are no restrictions on the type of client program used, providing it can use this protocol and deal with transactions synchronously.
    2. Build/Use a program that can build a valid request XML document and attach it via a POST parameter to a HTTPS request.
    POST /<URL_TO_SUBMISSION_SITE> HTTP/1.0
    Example

  • How to send te XML data using HTTPS post call & receiving response in ML

    ur present design does the HTTP post for XML data using PL/SQL stored procedure call to a Java program embedded in Oracle database as Oracle Java Stored procedure. The limitation with this is that we are able to do HTTP post; but with HTTPS post; we are not able to achieve because of certificates are not installed on Oracle database.
    we fiond that the certificates need to be installed on Oracle apps server; not on database server. As we have to go ultimately with HTTPS post in Production environment; we are planning to shift this part of program(sending XML through HTTPS post call & receiving response in middle layer-Apps server in this case).
    how i can do this plz give some solution

    If you can make the source app to an HTTP Post to the Oracle XML DB repository, and POST contains a schema based XML document you can use a trigger on the default table to validate the XML that is posted. The return message would need to be managed using a database trigger. You could raise an HTTP error which the source App would trap....
