Query regarding sending XML over HTTP Post request

Hello,
I am trying to send XML data from a server to client via HTTP Post request
And vice versa � receive the data by a client
Assume that the xml data looks something like
<?xml+version="1.0"?>
So my post query will look like
http://<IP Address>:<port>/
POST /MessageReceiver.jsp HTTP/1.0
Host: www.SomeHost.net
Content-Type: application/x-www-form-urlencoded
Content-Length: 38
%3C%3Fxml%2Bversion%3D%221.0%22%3F%3E+
This information will be received by the client and converted back to xml data.
My query is - is there some library/open-source stuff that
does the process of transcoding the entity's non-ASCII characters
at the server side
and decoding the URL back to human-readable form at the client side?
i.e. I need a simple mechanism to convert
<?xml+version="1.0"?>
to
%3C%3Fxml%2Bversion%3D%221.0%22%3F%3E+
at the server side, while sending data
and do the opposite at the client side to get the xml back.
Also could some one confirm if JTidy is a right tool to check if the xml is well-formed?
Or is there any other standard tool that checks for well-formed properties of xml?
regards,
Deepak.

java.net.URLEncoder / URLDecoder?
Also could some one confirm if JTidy is a right tool to check if the xml is well-formed?No, it's for parsing HTML. An XML parser is checking for well-formedness in any case.

Query regarding encoding/decoding of XML over HTTP Post request

Hello,
I am working on a project where I need to put SMS inside XML and
eventually transfer this XML via HTTP post from/to server/client.
Assuming the SMS to be 7-bit text the XML may look something like
<?xml+version="1.0"?>
<SMS
TESTMESSAGE
</SMS>
This XML when encoded in a HTML post may look something like
http://<IP Address>:<port>/
POST /MessageReceiver.jsp HTTP/1.0
Host: www.SomeHost.net
Content-Type: application/x-www-form-urlencoded
Content-Length: 90
xmlMsg=%3C%3Fxml+version%3D%221.0%22%3F%3E%0D%0A%3CSMS%0D%0A%09TESTMESSAGE0D%0A%3C%2FSMS%3E
This xml is UTF-8 (7-bit ASCII) by default since no encoding format has been specified.
My question - how will the encoding of xml change to - when 8 bit binary data
is transferred via xml.
for e.g.
<?xml+version="1.0"?>
<SMS
<!!!!!BINARY DATA!!!!!>
</SMS>
for such a file how/what shld the encoding be set to.
Further my spec-states the following.
"The content of the XML must respect the encoding. Thus a SMS
containing typically french characters must use ISO-8859-1 encoding"
"This code needs to work with both UTF-8 and UTF-16 standards (ASCII and Unicode). Because of this the parsing code should work internally with UTF-16 and translate up/down to/from UTF-8 (ASCII) only when dealing with the basic HTTP."
could anyone clarify this for me.

The first thing you need to do is clear up some fundamental misconceptions about character encodings. UTF-8 is not the same thing as "7-bit ASCII", and UTF-16 is not the same as "Unicode". Anyway, you're making this a lot more difficult than it needs to be. Just use UTF-8 to encode and decode all messages; it can handle all the characters from any language you're likely to run into.

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
nithya

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.

Sending xml over http

I have a WLS 6.0 servlet that receives XML transactions via a post method.
          Code snippet as follows:
          public void doPost(HttpServletRequest req, HttpServletResponse res)
          throws ServletException, IOException
          int txContentLength = req.getContentLength();
          //get entire input xml stream and store in a stringbuffer
          InputStream inp = req.getInputStream();
          BufferedReader br = new BufferedReader(new InputStreamReader(inp));
          byte[] ba = new byte[txContentLength];
          System.out.println("Reading...");
          int bytesRead = inp.read(ba);
          System.out.println("bytesRead= " + bytesRead);
          while(bytesRead < txContentLength) {
          int moreRead = inp.read(ba, bytesRead, (ba.length - bytesRead));
          if(moreRead == -1)
          break;
          bytesRead += moreRead;
          System.out.println("finished reading buffer...");
          StringBuffer sb = new StringBuffer(new String(ba));
          I have a java client on my PC that takes an XML file as input and sends the
          information to the servlet without any problems.
          The problem is a client that is connecting to our network via a T1
          connection. When they send transactions, about 1 out of every 4
          transactions makes it past the "Reading..." statement above. The other
          transactions appear to 'hang' when it hits the inp.read(ba) line above.
          From all indications, that servlet's execute thread appears 'hung' as if the
          inp.read() is waiting forever.
          I've tried using readLine() on the InputStream() and my local client program
          is unaffected - it works OK. The remote client is having problems using
          either method. The only difference I've noted with the remote client is
          that they are using HTTP 1.0 and I'm using HTTP 1.1. Initially, their
          mime-type was null but they've changed it to text/xml and no luck. I've
          even sent them my client code that is working and they are still having
          problems...
          Another strange anomoly is that req.getContentLength() is returning a valid
          number on the transactions that fail. For example, I had some debug code
          that showed the content length and it was always something like 4012 or
          3500, etc. Not -1 as I would expect...
          Has anyone run into this problem with receiving XML transactions?
          Thanks
          Rob Mason


Thanks for the suggestion - I went back and added a check on the
          contentLength to make sure it had a valid number before trying to call any
          'read' methods... still no luck.
          I did go in and put a try/catch around the read() logic below. The
          exception thrown is an InterruptedIOException. The docs say that this is
          thrown 'to indicate that an input or output transfer has been terminated
          because the thread performing it was terminated.'
          This would seem to indicate that WLS is having the problem - not the client?
          Via the console, under the Configuration section, my HTTP section has the
          following values:
          POST timeout secs: 10
          Max POST time: 10
          Max POST size: -1
          Is there anything else I can try on the server level?
          Thanks

Server to Rich Client sending XML over Http

I need to send XML data from a Servlet to a rich client over http.
Currently I am using HttpURLConnection and SaxTransformerFactory to do this.
Is it better to use SOAP or XML-RPC in this scenario?
Are there any good online tutorials comparing SOAP, XML-RPC and AXP-Java Net API?
What are the factors that I need to consider for choosing between these alternatives?
Please advice. Thanks in advance.

XML-RPC and SOAP use XML as a way to communicate, but they are used to invoke certain function calls in an application independend manner, not to be used to send XML data. So I'd say it depends on:
a) what do you do with the XML data?
b) will you be expanding the application?
c) how difficult is it to rework the current implementation?

HTTP POST Request with XML file in

Hi @ all,
I would like to send an HTTP Request with an XML File in the body to an SAP System
I have the target URL and the a XML File.
Now the question is. Is it possible to use something like the HTTP_POST FuBa to send an url post request with an xml file?
If yes can anybody give me a hint?
I have a php script which exactly do this coding. But to integrate it all in one system it is necessary to transform it into ABAP and call it there.
// compose url and request and call send function
function test($productID, $categoryID) {
     // create url
     $PIhost = "XXX.wdf.sap.corp";
     $PIport = "50080";
     $PIurl = "/sap/xi/adapter_plain";
     $PIurl .= "?sap-client=800";
     $PIurl .= "&service=XXX";
     $PIurl .= "&namespace=XXX";
     $PIurl .= "&interface=Frontend_Interface";
     $PIurl .= "&qos=EO";
     $PIurl .= "&sap-user=XXX";
     $PIurl .= "&sap-password=XXX";
     // create xml
     $request = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
     $request .="<n1:FrontendInbound_MessageType xmlns:n1=\"http://crmpiebay.com\">\n";
     $request .= "\t<FrontendInbound>\n";
     $request .= "\t\t<ProductName/>\n";
     $request .= "\t\t<ProductCategory>".$categoryID."</ProductCategory>\n";
     $request .= "\t\t<ProductID>".$productID."</ProductID>\n";
     $request .= "\t\t<MessageID/>\n";
     $request .= "\t</FrontendInbound>\n";
     $request .= "</n1:FrontendInbound_MessageType>";
     // send http request
     postToHost($PIhost, $PIport, $PIurl, $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"]."/".$_SERVER["PHP_SELF"], $request);
// send post request to PI server
function postToHost($host, $port, $path, $referer, $data_to_send) {
$fp = fsockopen($host, $port);
if($fp) {
     $res="";
       fputs($fp, "POST $path HTTP/1.1\r\n");
       fputs($fp, "Host: $host\r\n");
       fputs($fp, "Referer: $referer\r\n");
       fputs($fp, "Content-type: text/plain\r\n");
       fputs($fp, "Content-length: ". strlen($data_to_send) ."\r\n");
       fputs($fp, "Connection: close\r\n\r\n");
       fputs($fp, $data_to_send);
       while(!feof($fp)) {
           $res .= fgets($fp, 128);
       fclose($fp);
       return $res;
Would be great if anybody could give me a hint how to solve such a HTTP Post request with XML body data.
Thanks in advance.

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.

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

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();
}

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.

SOAP over HTTP/POST

Hi everyone,
I'd be eternally grateful if someone could provide me with a quick + easy solution to the following (basic?) task.
I have a user form with the required parameters and a submit button. I have an XML schema which specifies the format for the soap requests and responses. How do I accept user input, wrap it into a soap request, send it via HTTP/POST to a server ( http://localhost:9999/xyz/xyz), wait for a soap response and display the response in a readable format to the user when they press the submit button? Not that hard is it?!
Please try to be a specific as possible because I'm no Java expert. I'm just so confused with all the tutorials about wsdl, bpel, tomcat, jax ws, glassfish etc etc etc!
I use netbeans and java app server 9, though I'm open to other IDEs/servers.
Any help will be greatly appreciated,
Ruth

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.

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,

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.

Retrieve data/files fro HTTP POST request in On-Demand process

Hello,
I would like to integrate https://github.com/blueimp/jQuery-File-Upload to my APEX 4.2 application inside XE11g. I would like to use this kind of jQuery component, multiple file upload, use Drag & Drop, image resize, size limit, filter extensions etc...
This jQuery component and also others javascript uploaders sends data files to some defined URL. Developer need to build some servlet, php script or something on server side that will read files from HTTP request and stores it somewhere.
Do you know how to do it in APEX? How can I read data from HTTP POST request in PL/SQL? Now I can only call my On-Demand application process from javascript, but I am not able to read any data from HTTP POST in it.
Can I do it in APEX, or using MOD_PLSQL?
I would like to implement this:
1) some javascript uploader will call some URL of my application and sends HTTP POST with data files
2) I will read data files from HTTP POST and store them into database
3) I will create some HTTP response for javascript uploader
Thank you for some tips

I know about that existing plugin " Item Plugin - Multiple File Upload"
But I doesn't work in IE and has only basic features. Licence for commercial use is also needed. I would like to use some existing jQuery plugin. There are many of these plugins with nice features. And only one problem is that I need to create some server side process/servlet/script.. that can recieve HTTP request, get files from it and stores them into DB.
