XML over HTTP using BPEL (not using SOAP)... is this possible?

Hi there.
We're trying to expose a BPEL process which will be exclusively triggered from a HTTP POST. The Client Partner Link in the BPEL process models Oracle's Transparent PunchOut standard. This standard is strict XML-over-HTTP, SOAP is not involved.
However, I am getting issues when I POST the XML to BPEL. It is telling me that it requires a SOAPAction in the header. Again, the design dictates that this is raw XML over HTTP, so we are not to use any SOAP specific header values nor any kind of SOAP wrapper.
I deployed the sample 'HTTPPostService' process which was delivered with BPEL. I am seeing the same error when I try to POST XML to this process as well. I get a response (in a SOAP wrapper) saying that it wants a SOAPAction in the header. The WSDL used to create this sample process clearly does not bind to SOAP, (there are no mentions of the SOAPAction in the operation, etc) so I do not understand.
So, my question is: Is is possible to POST raw XML to a BPEL process? Or does BPEL require all processes to follow the SOAP 'protocol' ?
Thanks for any help.

I am also trying to do the same stuff. If i deploy the sample application HttpGetService, will i be able to send the request from browser the way we send typical http get request?
here is the url which i want to use to invoke Http get BPEL
http://cybage1:9700/httpbinding/default/HTTPGetService?ssn=10&id=20
but i am getting following exception

Using Business Service that supports XML over HTTP in OSB

Hi,
I needed to integrate my system with another legacy system that supports communication only through XML over HTTP. I am just trying to understand much about this XML over HTTP. I think in OSB, this is possible only possible through REST interfaces.
Is there any other way and what about HTTP bindings in WSDLs? can you please let me know if you have any insights.
I have gone through the urls about REST interfaces given in these forums. But just wanted to confirm the following scenaiors possible in OSB.
- Client will connect to SOAP based proxy service which will in turn call REST based business service.
- Client will connect to REST base proxy service which will in turn call SOAP based business service.
Following point is not clear from the URLs i went through so just wanted to confirm the following too:
- Client will connect to REST base proxy service which will in turn call SOAP based business service. And is it possible to add anything in soap header before calling soap based business service..
Thanks & Regards
Siva

Hi Siva,
XML over HTTP is a general use case and OSB supports it very well. REST is a special case and should be used when required. To know more about REST you may refer -
http://www.infoq.com/articles/rest-introduction
Now coming to OSB, SOAP and simple XML are two different cases. If you are creating XML type service then it is not binded to a WSDL/XSD but SOAP based service should always be binded with a WSDL. You may add/modify transport headers in OSB.
Evaluate your requirements and then decide what exactly you need to use. Few links which may be of your use -

Client call using   XML over Http using HttpClient

Using HTTPClient while calling HTTPPost method to generate request for external system using XML over http using below code
client.getState().setCredentials(new AuthScope(ipAddress,portNumber),new UsernamePasswordCredentials(username, password));
     PostMethod method = new PostMethod(url);
     String str = accDoc.toString();
method.setRequestEntity(new InputStreamRequestEntity(new ByteArrayInputStream(str.getBytes())));
method.setDoAuthentication( true );
int result = client.executeMethod(method);
server system getting 2 request. first request without basic authentcation details and second request with full auhentication details.
So unnecessary eatra call without authentication details is going during calling the client program using above code.
Please let me know which part of the above code is generationg extra call.
Thanks in advance for your help

I don't see nothing wrong with your code, there must be something else happening.
You sure you are not being some proxy server?? but even then you are making a post request so it shouldn't be happening.

Designing services for xml over http client requests

Hi
I am new to WebServices and Weblogic Integration. I have been using it for only over a month. I have a very basic design issue.
We have to provide a service that
1. accepts xml over http requests
2. Returns a request ack
3. Process Form a response -This activity consumes time so it will be made asynchronous
4. Send the response as xml over http
5. Wait for response ack
6. Get another type of request from client, the processign of which depends on the result of the previous request .. and so on..
The problem here is that Webservices accepts only SOAP messages but our client will send raw xml messages. Also we need to remember the condition of the previous state.
I dont know if my assumption that SOAP is used is right.
Please tell me how to design a raw xml based system without using SOAP messages.
Thanks

Basic Question: plain XML over HTTP

I would be getting messages in plain XML over HTTP. What should I use to receive those messages. Server is not SOAP based, so client cannot be SOAP based. Should I use JAX-RPC, but when I looked at the documentation, it is giving info regarding SOAP and plain xml over http. Can anyone help me?
Thanks

From my understanding, you would be getting a plain xml string by connecting to a server over http.
You can is DOM or SAX apis to parse this xml input stream.
For eg: if you are using DOM apis, then you can pass the input stream of the HttpURLConnection as follow...
     DocumentBuilderFactory buildFactory = DocumentBuilderFactory.newInstance();
     buildFactory.setIgnoringElementContentWhitespace(false);
     buildFactory.setValidating(false);
     DocumentBuilder docBuilder = buildFactory.newDocumentBuilder();
     URL url=new URL("http://someserver.com/abc.jsp");
     HttpURLConnection conn= (HttpURLConnection)url.openConnection();
     InputStream in= conn.getInputStream();
     Document doc = docBuilder.parse(in);
     ..Hope this helps...

XML over HTTP out of the EJB container

I need to communicate with a legacy system via XML over HTTP from the EJB layer. I created a custom solution for this on a previous assignment using Castor for the marshaling etc. and standard JDK classes for the opening the HTTP connection, posting etc. I am thinking of implementing a similar solution in the using the DAO pattern. Are there any new open-source implementations for such XML/HTTP connectivity (non-SOAP)? Surely there is somethign out there!
Thanks,
-Chris

In general, it is bad design to make network calls from the EJB layer, just as it is against the spec to do things such as create threads, write to the file system, etc.
I know this doesn't answer your question but it is something to consider.

Any good XML over HTTP examples?

Hi,
Does anyone know of a good example of using a XML over HTTP web service? Especially one that would be easily graspable by someone who's new to web services (read: me)?
Is there a way to generate stub classes from a WSDL? I tried to do it in NetBeans but it didn't work, maybe NetBeans expects SOAP web services?
Thanks

Hi,
This use case seems to be best handled using a RESTful Web Service. Check the Restlet project for a supporting framework:

Accessing Java webservice (XML over http) via WCF or HTTP adapter with content-type and authorization HTTP headers with POST method

Hi Team,
I need to access Java web service which is simple service and accepts and returns XML over HTTP. No credentials are needed to access the service. We need to pass following two HTTP headers (Content-Type and Authorization) along with XML request message:
<GetStatus> message is being constructed in the orchestration and URI is constant to access.
Which adapter shall I use to get the response back? I tried using WCF-WSHttp with Security Mode = Transport, and different options of client credential types but every time, error returned stating:
System.Net.WebException:
The HTTP request is unauthorized with client authentication scheme 'Basic'. The
authentication header received from the server was 'Basic realm='.
Authentication failed for principal Basic. Message payload is of type:
String
In Fiddler, request looks line following
POST <https://URL/GetServiceReopnse HTTP/1.1
Content-Type: application/xml
Authorization: Basic cmVmU3RhdHN2Y19kgeRfsdfs=
Host: <Server name>
<GetStatus XMLNS="http://server.com/.....">
<OrgId>232323</OrgId>
<HubId>3232342323</HubId>
</GetStatus>
MMK-007

First, you should not use the HTTP Adapter because it's been deprecated and replaced by WCF.
Start with the WCF-Custom Adapter and select the customBinding.
You should start with the textMessageEncoder and httpTransport and go from there.

Post XML over HTTPS in a loop

HI,
I have a requirement to post XMLs over HTTPS. I also am supposed to retrieve the response XML, interpret it and do some processing based on the response status in the response XML. This has to be done for each XML.
Currently I am establishing a new HTTPsURLConnection for each XML, wrting the XML to output stream, retrieving the response from input stream and then releasing the connection using disconnect() method.
Is this the recommended approach or should I be creating just one connection for posting all the XMLs? Also, does java use some kind of connection pooling while creating HTTPURLConnection?
I am frequently getting "SocketTimeoutException Exception --> connect timed out" while processing large number of XMLs. Is this exception due to large number of connections that I am creating?
This program is running as a stand alone program on unix box.
Regards,
Jacob

Is this the recommended approachYes.
or should I be creating just one connection for posting all the XMLs?No.
Also, does java use some kind of connection pooling while creating HTTPURLConnection? Yes.
I am frequently getting "SocketTimeoutException Exception --> connect timed out" while processing large number of XMLs. Is this exception due to large number of connections that I am creating?Could be, especially if you're doing them in parallel.

Preview failed because Adobe Muse could not make a connection over HTTP. The most common cause of this is Firewall software which prevents HTTP connections. You may need to change Firewall settings to allow Adobe Muse to make connections.

no firewall at all, in win 8.1, turned it off for all networks
ftp and publish works just fine

Post XML over HTTPS

We are trying to do the following. Can anyone help by providing any pointers as how to do it.
1. A java client will be posting XML over http(s) to the Tomcat server.
2. The Tomcat server has to do the following:
- Validate the user credentails and verify that it is an valid user on IDM
- Do some DB operations and return back a response XML
We are trying to do this by having the Java client post XML over http to a jsp hosted on the Tomcat server
How do i retrieve the XML data from the HTTP post (from the HTTP body) ?
Thanks

try the below example to read data over https,
import java.net.*;
import java.io.*;
import javax.net.ssl.*;
public class SSLSocketClient {
public static void main(String[] args) throws Exception {
     String url="https://secure.com";
          try {
               SSLSocketFactory factory = (SSLSocketFactory)SSLSocketFactory.getDefault();
            SSLSocket socket = (SSLSocket)factory.createSocket(url, 443);
            socket.startHandshake();
            /* read response */
            BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            String inputLine;
            while ((inputLine = in.readLine()) != null)
                System.out.println(inputLine);
            in.close();
            socket.close();
        } catch (Exception e) {
            e.printStackTrace();

Please explain personal hotspot and when should I use or not use?

I Don't understand personal hotspot. Is there times to use and not use it?

Personal hotspot is a way to use the cellular data connection on your iPhone to allow a computer that does not have an internet connection to have access to the internet. It is a good way to use up huge amounts of cellular data and is only supported or possible if your cellular plan allows it.
There is something similar where a computer that has an internet connection can share that connection -- but I'm not sure that is what you are asking about.
Normally you don't need to manually turn cellular data usage off. The iPhone is designed to automatically use wi-fi when it is connected and to automatically switch to cellular data if wi-fi is not connected.
If you are asking about text messaging:
1) iMessage -- only to another iPhone or Apple device that has iMessage turned on and you also need iMessage turned on. It will use internet if you have it, your cellular data plan if you do not have wi-fi connection
2) regular texts. They don't use wi-fi but they also don't count against your cellular data usage. They count against your plans text allowance.
3) 3rd party apps such as WhatsApp -- you would need to investigate them yourself
