Send parameters to XI by HTTP

Hi friends,
I would like to offer an interface in XI to establish a synchronous communication for adapters HTTP or XI.
Would need to run the service in XI from a URL like:
http://host_xi:port_xi/path_xi/service_xi?parameter1=X&parameter2=Y&...
And capture in XI a message with the parameters through a HTTP request to the URL above.
I have seen examples of this, but sending the message in XML format from the client HTTP.
Is it possible to do what I need?
Thanks,
Jose.

Hi friends,
I think I already have the solution. To enable communication HTTP and send the parameters by GET method from the sender system, performed as follows:
With a BSP application is able to capture the parameters by GET method.
In a Controller of the BSP is assign the class controller that processes requests HTTP. This class inherits from the controller class CL_BSP_CONTROLLER2.
It reimplement the method DO_REQUEST, and this prepares the URL with the necessary parameters and XML Payload to be sent to Integration Engine of SAP XI.
Thank you all for the help,
Jose.

How best to send double byte characters as http params

Hi all
I have a web app that accepts text that can be in many languages.
I build up a http string and send the text as parameters to another webserver. Hence, whatever text I receive i need to be able to represent on a http query string.
The parameters are sent as urlencoded UTF8. They are decoded by the second webserver back into unicode and saved to the db.
Occassionally i find a character that i am unable to convert to a utf8 string and send as a parameter (usually a SJIS character). When this occurs, the character is encoded as '3F' - a question mark.
What is the best way to send double byte characters as http parameters so they always are sent faithfully and not as question marks? Is my only option to use UTF16?
example code
<code>
public class UTF8Test {
public static void main(String args[]) {
encodeString("\u7740", "%E7%9D%80"); // encoded UTF8 string contains question mark (3F)
encodeString("\u65E5", "%E6%97%A5"); // this other japanese character converts fine
private static void encodeString(String unicode, String expectedResult) {
try {
String utf8 = new String(unicode.getBytes("UTF8"));
String utf16 = new String(unicode.getBytes("UTF16"));
String encoded = java.net.URLEncoder.encode(utf8);
String encoded2 = java.net.URLEncoder.encode(utf16);
System.out.println();
System.out.println("encoded string is:" + encoded);
System.out.println("expected encoding result was:" + expectedResult);
System.out.println();
System.out.println("encoded string16 is:" + encoded2);
System.out.println();
} catch (Exception e) {
e.printStackTrace();
</code>
Any help would be greatly appreciated. I have been struggling with this for quite some time and I can hear the deadline approaching all too quickly
Thanks
Matt

Hi Matt,
one last visit to the round trip issue:
in the Sun example, note that UTF8 encoding is used in the method that produces the byte array as well as in the method that creates the second string. This is equivalent to calling:
String roundTrip = new String(original.getBytes("UTF8"), "UTF8");//sun exampleWhereas, in your code you were calling:
String utf8 = new String(unicode.getBytes("UTF8"))//Matt's code
[/code attracted
The difference is crucial. When you call the string constructor without a second (encoding) argument, the default encoding (usually Cp1252) is used. Therefore your code is equivalent toString utf8 = new String(unicode.getBytes("UTF8"), "Cp1252")//Matt's code
i.e.you are encoding with one transformation format and decoding back with a different transformation format, so in general you won't get your original string back.
Regarding safely sending multi-byte characters across the Internet, I'm not completely sure what the situation is because I don't do it myself. (When our program is run as an applet, the only interaction it has with the web server is to download various files). I've seen lots of people on this forum describing problems sending multi-byte characters and I can't tell whether the problem is with the software or with the programming. Two possible methods come to mind (of course you need to find out what your third party software is doing):
1) use the DataOutput/InputStreams writeUTF/readUTF methods
2) use the InputStreamReader/OutputStreamWriter pair with UTF8 encoding
See this thread:
http://forum.java.sun.com/thread.jsp?forum=16&thread=168630
You should stick to UTF8. It is designed so that the bytes generated by encoding non-ASCII characters can be safely transmitted across the Internet. Bytes generated by UTF16 can be just about anything.
Here's what I suggest:
I am running a version of the Sun tutorial that has a program running on a server to which I can send a string and the program sends back the string reversed.
http://java.sun.com/docs/books/tutorial/networking/urls/readingWriting.html
I haven't tried sending multi-byte characters but I will do so and test whether there are any transmission problems. (Assuming that the Sun cgi program itself correctly handles characters).
More later,
regards,
Joe
P.S.
I thought one the reasons for the existence of UTF8 was to
represent things like multi-byte characters in an ascii format?Not exactly. UTF8 encodes ascii characters into single bytes with the same byte values as ASCII encoding. This means that a document consisting entirely of ASCII characters is the same whether it was encoded as UTF8 or ASCII and can consequently be read in any ASCII document reader (e.g.notepad).

URLConnection problems(Sending parameters with URL)

Guys i have some problems with sending parameters through URL using URLConnection class.
That's my code:
URL url = new URL("http://kiosk.homebank.kz:9090/default.asp?action=SaveContact&src=C_HOMEBANK&ClientId="+request.getParameter("ClientId")+
                    "&IdService="+request.getParameter("IdService")+
                    "&Contact="+URLEncoder.encode(request.getParameter("Contact"),"utf-8")+
                    "&Number="+URLEncoder.encode(request.getParameter("Number"),"utf-8")+
                    "&Work="+URLEncoder.encode(request.getParameter("Work"),"utf-8")+
                    "&Mobile="+URLEncoder.encode(request.getParameter("Mobile"),"utf-8"));
        URLConnection connection = url.openConnection();
        connection.setDoInput(true);
        connection.setDoOutput(true);I want just send these parameters without going to this link. How can i do it using URLConnection class? Help please!

Try using this set method in the URL class (query is the parameters):
protected void set(String protocol,
String host,
int port,
String authority,
String userInfo,
String path,
String query,
String ref)

Send parameters from java to SSRS 2008 R2

If the report is published in report server then the easiest way is to use URL and display it in an IE browser. We can even send parameters to the URL. Refer
http://msdn.microsoft.com/en-us/library/ms152835.aspx
There is another method that we can access a published report, i.e using
SSRS Web Services.
Otherwise if you are trying to access SSRS report file then you may need to create object or report viewer control(.net framework).

Sending parameters to Flex executable

Hi,
Is it possible that we can send parameters to Flex executable(s)? By Flex executable I meant, the installed .EXE(for Windows) or .APP(for MacOS), after having them installed through an EXE or DMG created with command prompt.
Thanks.

I've seen a discussion with running executable and passing parameters with Runtime.exec from Adobe : http://forums.oracle.com/forums/thread.jspa?threadID=1686479
But will it work for Flex compiled EXE or SWF also, and how can those parameters catch inside (?)

Consider the lifecycle.
You request page "index.jsp" It runs index.jsp and produces html. It sets the request attribute "myparameter"
You request page middle.jsp. It runs middle.jsp.
Note that this progression requires two seperate requests - one for "index.jsp" and then another for "middle.jsp", which sends the request parameters from the form from your browser to middle.jsp.
Request attributes only last the life of one request - so when you request "middle.jsp" the request attribute set when running "index.jsp" is not available.

Sending parameters to reports by using Run_Report_Object

Hi All,
How do I send parameters to report while using Run_Report_Object built-in ?
Thanks in advance.
Regards,
Sanjay Kanakath

hello,
there is a builtin for setting the parameters :
from the forms builder online help :
DECLARE
     repid REPORT_OBJECT;
     report_prop VARCHAR2(20);
BEGIN
     repid := find_report_object('report4');
     SET_REPORT_OBJECT_PROPERTY(repid, REPORT_EXECUTION_MODE, BATCH);
     SET_REPORT_OBJECT_PROPERTY(repid, REPORT_COMM_MODE, SYNCHRONOUS);
     SET_REPORT_OBJECT_PROPERTY(repid, REPORT_DESTYPE, FILE);
END;
you can use
SET_REPORT_OBJECT_PROPERTY(repid,
REPORT_OTHER,
'deptno=10');
to set the Other Parameters property of the report object.

How can i send xml file with a http servlet request

Hi
Please tell me how can I send a xml file into http servlet request.
I have a servlet(action) java file.From this servlet I have generate a xml file. Now I need to send that xml file to another servlet with http servlet request object.
Dave.

When you say you have generated an XML file what do you mean?
Is it a file stored on disk? Then pass the file path as a string to the servlet.
Is it stored in memory as an object? The pass a reference to the object to the servlet.
Or are you asking how to communicate between servlets?
Look in the JavaDocs for the RequestDispatcher class. You can use this class to forward the request to another servlet. Data can be passes using the RequestDispatcher by storing it as attributes using the request getAttribute and setAttribute methods. Also described in the JavaDOcs.
http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/RequestDispatcher.html

How to send Parameters FORM to PHP WEB Page with method POST (secure)?

Hello everyone,
i hope someone can help me to find a solution to this problem!
i have to send "+precious+" parameters from an oracle form to php page, like username and password, with a secure method... i tried with WEB.SHOW_DOCUMENT procedure but it uses GET Method and when the web page open up you can read those parameters in the url...no good!
some suggestion?
Thank a lot in advance... FMicio

The other way you have is to make a PJC java bean ...
which uses HTTPClient library..
for example:
PostMethod post = new PostMethod("http://jakarata.apache.org/");
        NameValuePair[] data = {
          new NameValuePair("user", "joe"),
          new NameValuePair("password", "bloggs")
        post.setRequestBody(data);
        // execute method and handle any error responses.
        InputStream in = post.getResponseBodyAsStream();
        // handle response.I have done a multipart form data post to upload files to my db over httpClient.. and other things...
Or with java.net.* api-s
try {
    // Construct data
    String data = URLEncoder.encode("key1", "UTF-8") + "=" + URLEncoder.encode("value1", "UTF-8");
    data += "&" + URLEncoder.encode("key2", "UTF-8") + "=" + URLEncoder.encode("value2", "UTF-8");
    // Send data
    URL url = new URL("http://hostname:80/cgi");
    URLConnection conn = url.openConnection();
    conn.setDoOutput(true);
    OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
    wr.write(data);
    wr.flush();
    // Get the response
    BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
    String line;
    while ((line = rd.readLine()) != null) {
        // Process line...
    wr.close();
    rd.close();
} catch (Exception e) {
}Or you can call your web page (post data) from your database

How to send a document in net.HTTP.request as a POST variable?

I have read and reread the doc on net.HTTP.request, and it says I can pass an argument of oRequest, but I have not succeeded at passing in the current document, which is what I want to do.
I've tried app.activeDocs[0], or encoding that to a string, but though it makes the call without error, nothing is sent.
Should oRequest be simply a document, or a variable made up of name-value pairs? How do we send multiple parameters to a POST otherwise?
I've succeeded fine with calling using GET, but when I tried to pass the document as a GET variable, I got nothing either.
I'm sending to a LiveCycle REST end point so either POST or GET is fine.
Thanks!

POSTing the current document is straightforward *provided* your script is running outside the document context (i.e. in the console or a folder-level script). There's no access from doc-level scripts for obvious reasons.
For example, putting this in the JS console will POST the current file to a URL:
Net.HTTP.request({
cVerb:'POST',
cURL: 'http://localhost/submit.php',
oRequest: Collab.documentToStream(this),
oHandler: {
response: function (msg, uri, err) {
if (err!=undefined) app.alert(msg);
Your problem with talking to a vanilla webservice is that you cannot send the RFC1867 delimeters (i.e. form a "multipart/form-data" request) as the ReadStream object doesn't have a concatenation method in the Acrobat JSAPI. That's also how you would usually prepend other form fields, but if you're careful with your server-side coding you can send those as GET parameters in cURL. Normally you'd be polite and pass a Context-Type header in the aHeaders array - it won't matter to the transmission process but will allow your webservice to predict what the heck it's been sent.
Your webservice will then have to read the raw data. In PHP for example, you won't get anything in the $_FILES global but you can grab the PDF by reading everything from the input buffer, with the line:
$pdf = file_get_contents("php://input");
If that line was in the server script that the above JS code was aimed at, the variable $pdf will contain an exact binary copy of the currently-open document.

HTTP Sender with EOIO leads to HTTP Response 500

Hello everybody,
since we are using SP12 we have problems with the HTTP sender when using EOIO. If I use the two parameters ....qos=EOIO&queueid=myQueue... I got a HTTP Reponse Code 500: Internal Server Error in the sender system (for the test I use a Java Program). When I use the qos EO (without a queue ID) it works.
Does anybody now this problem?
