Http's GET & POST.

I'm trying to write a program to transfer files over "https" using "GET" & "POST", but I do not know where to start from, like which java packages to use, sample programs etc.
Any pointers would be most helpful.
Thanks a lot in advance.

http://java.sun.com/products/jsse/index.htmlthanks. But Do I need to learn java serverlets to do this ? Where can I get help on how to start-up?

You're wanting to write a servlet. The package for servlets is javax.servlet and javax.servlet.http. There is no difference in accessing a servlet with https.
You can find a good reference implementation of the servlet code on Apache's Tomcat.

HTTP GET/POST: J2EE Design Strategy w.r.t servlet implementation

I am in process of designing a J2EE application with browser interface. I have thought of having "Front Controller" Servlet for all HTTP-GET requests and "Action Controller" servlet for all HTTP-POST requests.
I have worked this distinction on the basis that GET request maps directly to page being requested and POST request corresponds to action being performed on some page. Here in fact the design is driven by appropriate selection between GET or POST. So all possible requests on the site should get properly mapped to action or page.
Decision of two servlets is merely to divide the load on single servlet. There being well defined logical (page and action) and implementation (GET/POST) boundary, the division seems workable.
Before actually finalizing this decision I need to know any inputs (pros and cons) of this approach.
Further If I start mapping to actual scenerios,
Request for home page,
Request from HREFs,
Request where new transaction is started
will always be GET Requests.
However what about request method (POST or GET) for update employee profile page when emp. id is available already available on first page ??
And further
Is this GET/POST divison always possible ??
Any constraints that any one can see in this mapping ??
Any comments on the update employee profile scenerio - GET/POST - page/action ??
PS: Pl. discard error scenerios for the moment.

how would you direct the GET requests to one servlet and the POST requests to the other?
Wouldn't they need to pass thru' yet another servlet to decide which is which (GET or POST), and redirect them accordingly?
I would have both GET and POST handled by the same single-point-of-entry servlet. For example, not all data is sent to the server via a POST - you can send form data via a GET, using name/value pairs in the url.

HTTP GET/POST method support in ESB/BPEL

hi,
I want to call HTTP URL using GET/POST method from ESB or BPEL. Can you please tell me how this can be achieved?

Obtaining custom HTTP GET / POST parameters of variable length in Application Process

Hi, I'm trying to connect a javascript UI control within my page to an APEX Application Process.
The control calls the application process via AJAX and appends a variable number of GET / POST parameters to its URL.
What is the best way to obtain these parameters from within the PLSQL procedure of the process? Or is there a better way to connect my javascript AJAX control to the Database behind my APEX app?
Thanks,
Steffi

Steffi,
I'm using APEX 4.1 and I've not used Treegrid before. It does look pretty interesting.
Firstly, I'm not sure if you are aware but GET requests aren't as secure as POST requests. GET simply appends a key/value pair to the server as part of the url which can be easily sniffed. POST request on the other hand sends the data as key/value pairs to the server in the header which makes it harder to intercept. This is why APEX outputs forms with POST methods.
Secondly, back to your original question.I'm not sure this is possible with an Application Process. In the passed I've used POST methods to pass values to my Application Process. I have some code using native jQuery if you would like to see how its done. Alternatively, if you convert your application process to a standard pl/sql procedure (i.e SQL Workshop>Object Browser>Procedures) you can call this procedure and pass in values as you would with any PHP page.
Simple example (untested)
CREATE OR REPLACE PROCEDURE "foo" ( my_name varchar(20)
     , count NUMBER)
IS
     p_name varchar(20) := my_name;
     p_count NUMBER     := count;
BEGIN
--Do what you want
--output something
   htp.p(p_count || '.: '|| p_name);
END;
The url on the page (or ajax call) would be something like "/pls/apex/{MY SCHEMA}.foo?my_name=Alistair&count=1"
Of course for text you will need to escape single colons and special characters etc.
I would really like to help you further so if you could create a working demo using a free workspace on http://www.apex.oracle.com and provide me with demo username/password. I can try and have a better look for you.
In all honesty, I'm sure you would be looking to create this as a plugin so that you can easily reuse it in various parts of your application and can easily update it or maintain it. I can help you with that as well if you want.

This isn't a straight FORM Post as in the http binding support in WSDL. It posts
a soap message.
It's apparent that Workshop supports form-post and form-get.
But I dont see how it is done with straight WebLogic webservices. Does WebLogic
server read the web-services.xml or the WSDL file? I dont see a way to put in
http-post binding in the former and in the latter it seems to be ignored.
Can someone clarify.
Thanks.

HTTP Transformation using POST Method

Hi, I will have to use POST method with header as application/json to get the results in http transformation. I downloaded the RESTFUL client utility from Chrome, to see how JSON would look like by passing parameters and the result is displayed as expected. But I'm not sure how the URL to be constructed in HTTP transformation and appreciate if you have any suggestions. My URLL http://dev1.com/contract-api/contract/public/contractValidationMy input parameters: {"hierarchies":[10],"properties":[18],"licId":123} If I use the above URL and parameters in RESTFUL client, I'm getting the output, but having difficulty in setting up the URL using HTTP transformation. RegardsSelva

Thanks Marc.
Let me rephrase the scenario.
I have an external application which is capable of sending information only in XML through HTTP requests. It does not send SOAP messages. I guess in this case, we would need to use the HTTP binding using POST method. Much like the sample at http://blogs.oracle.com/reynolds/2005/09/invoking_bpel_from_an_html_for.html which uses the GET method.
In this sample reynolds is using the GET method. I have been trying to get the POST method to work.

HTTP Request in post

Hi all,
    I want to implement an interface between SAP and a bank.
    The bank provide a HTTP server, when I sent a HTTP request in post method with an XML body to the server, it will answer a response with an XML body to me.
    I search lots of topic about HTTP request in ABAP, then I know I must create a object ref to IF_HTTP_CLIENT, but I don't know which parameter I need to input, and how can I receive the response, and so on.....
    So, I want some simple code, can you help me? thanks in advance!
    PS: Does I need to configure a HTTP Adapter? I never use XI so I don't know any adapter, I just want to sent a request and receive a response in ABAP
Edited by: Wei Jie Pan on Mar 23, 2009 3:54 AM

you can use HttpURLConnection to POST or GET request in your backing bean
See this example
    public void youTubeServerAction(ClientEvent clientEvent) {
      URL               url;
      HttpURLConnection conn;
      StringBuffer strBuffer = new StringBuffer();
        try {
            url = new URL("http://gdata.youtube.com/feeds/users/thomasthiele/uploads?alt=json-in-script&callback=showMyVideos&max-results=50");
            conn = (HttpURLConnection) url.openConnection();
            conn.setDoOutput(true);
            conn.setRequestMethod("GET");                   // >> set here POST request
            InputStream in = conn.getInputStream();
            int c;
            while ((c = in.read()) != -1)
                strBuffer.append((char)c);
            System.out.println(strBuffer.toString());
            in.close();
            conn.disconnect();
        } catch (Exception e) {
            e.printStackTrace();
        FacesContext fctx = FacesContext.getCurrentInstance();
        ExtendedRenderKitService serv =
            Service.getRenderKitService(fctx, ExtendedRenderKitService.class);
        System.out.println("SOURCE " + strBuffer.toString());
        serv.addScript(fctx, strBuffer.toString());
    }Good luck.

Non-SOAP WSDL bindings? (GET/POST?)

Hi,
I would like to know if Aqualogic Service Bus can transform SOAP requests into GET/POST requests?
My organization has several legacy services, which are really just CGIs that accept GET query parameters and return XML results in the HTTP response body.
I would like to integrate those services into an SOA based environment.
I hoped that I could model my legacy services as Web Services using an HTTP GET binding (using WSDL). Then I could import them into Aqualogic and design a transforming proxy in front of them. Is that possible?
Thanks,
Erik

Erik,
just define a SOAP based proxy service and before calling the CGI based business service extract data from the SOAP body and add it to the http transport headers for the outgoing business service call. We have done this succesfully in some projects.

How to create a proxy that accept requestes get/post in the same time?

Hi everybody,
I have two questions with Service Bus 11gR1.
I have to create a proxy in https that accept request get/post in the same time, also this proxy should be able to recognize the common name of the certificate.
Is it possibile?
Thanks a lot.
Ettore

The approach I mentioned is part of correctly configuring client cert authentication. For client cert authentication to succeed weblogic expects the user derived from the certificate by the user name mapper class to exist ( just exist , it wont check the password) in its security realm. The problem you have mentioned is common for any type of 'authentication' and not just specific to this approach.
The user name mapper class can be configured to accept any attribute in the certificate DN as the mapped user. Since the thread starter is interested in CN, then he has to set CN as the mapping attribute.

Need help : how to send 3 parameters over http using Java POST

I am trying to sending some data to agency company over http using Java POST
They need 3 parameters and some contents like below
1. Cmd : cmd=_RequestInsertNewLead
2 Live : False
3 XMLData : 3C%3Fxml+version%3D%........
I already have XML done ,but I don't know how to send these guy over http
is that like
this.out = new DataOutputStream(os);
out.writeBytes("Cmd");
out.writeBytes(" cmd=_RequestInsertNewLead");
out.writeBytes(" Live ");
out.writeBytes("False");
anyone could give help :)

First of all, are you getting any exception?
You didn't put much logging information in your code.
You can also try this.Instead of doing sos.println(".....") try to build the output string using string buffer.
Like:
StringBuffer sb = new StringBuffer();
sb.append("Some output");
sb.append("More output");
sos.print(sb.toString());
sos.flush();Let me know if this works.

Reports not getting posted after webserver bounce.

Hi Gurus,
The reports are not getting posted after the webserver bounce occurred. This is the same webserver on which report repository is located.
However if we boot this webserver first and run a report, then it gets posted. And then after all the other webservers are booted, then the issue does not occur.
Please advise.
