HTTP POST using JSP

Is it possible to submit a data using HTTP POST from a JSP. In a JSP I am generating a XML. For example JSP URL is http://www.test/xml.jsp
In the xml.jsp:-
<test>
<test1>
Testing 1
</test1>
<test2>
Testing 2
</test2>
</test>
When I call http://www.test/xml.jsp, I should receive the content in the xml.jsp as a HTTP POST. Is this possible using JSP or do I have to use only servlet?
Thanks

Hi,
yes, it's possible to submit data from JSP using POST method.
It is even possible to do it from HTML. Set <form method="post"...>, that's all. You can't submit data using POST by typing any specific address etc. in Your browser, only GET parameters can be sent in such a way.

Bhavesh,
Could you please share your thoughts on the following....
1. Enabled SSL on JAVA engine. - can access https://server:httpsprot(50001)/index.html - but gives a warning that cerficate expired.
2. We have messages coming from a vendor - outside our firewall. - We have not exchanged any certs or keys.
I have configured a sender SOAP with -
Transprot Protocol - HTTP
Message Protocol - SOAP 1.1
HTTPS security Level - HTTPS Without Client Authentication.
I have generated a webservice, used SOAP UI - to send a SOAP request to XI. I can see the message in moni. The end point in the SOAP UI is -
https://<SERVER>:<HTTPS Port>/XISOAPAdapter/MessageServlet?channel=party:service:channel
Is there anything that I will have to do to accept the messages from the vendor.

Reading Parameters of a http post in JSP

I am migrating a Data Web Bean that extends EditCurrentRecord from JDev 3.1 to 3.2
In old 3.1 days, one could read the HTTP parameters using request.getParameter(). Now, the implementation of EditCurrentRecord uses an OrdHttpUploadRequest to read the parameters, which is not (!) documentated nor included as source file. Given the library.ini configuration, it belongs to some intermedia stuff ???
I somewhat understand the need for OrdHttpUploadRequest to deal with large files, but why doesn't request.getParameter work any more ? Has it something to do with Serverl 2.1 / 2.2 API ?
Pascal

The EditCurrentRecord now uses the multipart mime type in order to support interMedia. This causes the Http parameters to be in a different format that the OrdHttpRequest can decode.

Help!!!.....HTTP Post to JSP with parameters in URL also....

I am trying to emulate a webpage that is POSTing info to a URL which is a JSP that also has parameters in the URL. I am having problems getting my java code to emulate doing this task manually through a web browser.
The webpage has the following HTML code:
<form method=post action=hello.jsp?y=60245&x=698>
<input type="text" name="name" value="jim">
<input type=submit name=submit value="Now">
</form>
...notice that the jsp referenced above has some parameters appended to the url, but the method is post.
Here's my code to try to do the same thing as if I manually pressed the submit button in a browser:
URL url = new URL("hello.jsp?y=60245&x=698");
httpConnection = (HttpURLConnection)url.openConnection();
httpConnection.setRequestMethod("POST");
httpConnection.setDoOutput(true);
httpConnection.setDoInput(true);
httpConnection.setUseCaches(false);
httpConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
DataOutputStream output = new DataOutputStream(httpConnection.getOutputStream());
output.writeBytes("name=jim&submit=Now");
output.flush();
BufferedReader is = new BufferedReader(new InputStreamReader(httpConnection.getInputStream()));
Writer w = new BufferedWriter(new FileWriter("CapturedHTML.html"));
int data=0,count=0;
while(data!=-1){
      data = is.read();
      w.write(data);
      count++;
System.out.println(count + " bytes read");
w.flush();
w.close();
is.close();
output.close();I write out the result to a file so that I can see the HTML returned by the JSP. It's a completely different webpage than if I were to have manually clicked the submit button on a browser.
WHY???????? How is a browser actually sending the info to the jsp when it has info both in its URL and in the post data?

I might be wrong, but the browser could have some sort of mechanism built into it which makes sure that the parameters appended to the url are actually passed as a part of a POST requst, while a Java program might not pass them at all.
Have you tried passing these params: y=60245&x=698 as a part of a POST request, rather than adding them to the URL.
Also, how do u know which response from JSP is correct? They might be different but do u know which one is the correct one? Do you know what the response should look like? that would make things a lot easier as u could figure out what parameters are causing the differences in the responses u r getting.

How to send/receive XML using JSP

Hi,
I'm new to all this JSP/XML stuff so apologies if this is trivial.
I'm trying to send an XML file via HTTP POST using JSP. Anyone know how to do this?
Once the XML has been sent, how do you use JSP to request the XML file? I've figured out how to parse it already.
Also, is it possible to call xsql directly within JSP?
Thanks!

I'm trying to send an XML file via HTTP POST using JSP. Anyone know how to do this?The question is, does anybody understand what you mean by this. Let me take a guess. You want to upload an XML file to a server. If this guess is right, then the answer is don't use JSP to do that. JSP is for generating output to be sent to a client. Use a servlet to handle an upload. And you don't need to write it yourself, there are already several file-upload servlets available on the web.
Second guess: you have a POST request that asks your server to send an XML file back to the client. If it's a static XML file you don't need a JSP or a servlet or anything, just let your web server handle it just like any other static file. If it's dynamically generated then there's an answer worth giving, but I doubt that this is your question. But if it is, let us know.

HTTP POST with XML with HTTPService

Hi,
I need to be able to send an HTTP POST request to a server I
have on Tomcat. In the body of the POST Request I need to have the
following:
<setView domain="someDomain" view="macro" />
We have tried the following using the HTTPService, but with
no such luck
<mx:HTTPService id="setViewHTTPService" url="{serverURL}"
resultFormat="object" contentType="application/xml"
method="POST">
<mx:request>
<setView domain="abc" view="xyz" />
</mx:request>
</mx:HTTPService>
Is there a way for us to specify the body of the HTTP Post
using HTTPService, or a different class for that matter.

var variables:URLVariables = new
URLVariables("name=Franklin");
//or variables.name = "Franklin";
var request:URLRequest = new URLRequest();
request.url = "
http://www.[yourdomain
request.method = URLRequestMethod.POST;
request.data = variables;
var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.VARIABLES;
loader.addEventListener(Event.COMPLETE, completeHandler);
try
loader.load(request);
catch (error:Error)
trace("Unable to load URL");
function completeHandler(event:Event):void
trace(event.target.data.welcomeMessage);
This is in the help documentation and what I generally use.

HTTP Post WSDL in J2EE/HOME ?

A customer created a BPEL process which has a partner-link defined for a WSDL located in the same directory as the project's bpel.xml file. The partner-link is to perform a http post using http binding. (basically the WSDL points to a deployed Servlet)
When the process is initiated via the BPEL Console an error in the domain.log occurs stating that the WSDL cannot be found in j2ee/home.
The customer can use "wsdlLocation" and "wsdlRuntimeLocation" in bpel.xml, to work past the error but why are we searching for the WSDL in j2ee/home ?
The error:
<summary>Failed to read wsdl. Error happened when reading wsdl at
"HTTPPostService.wsdl", because "WSDLException: faultCode=PARSER_ERROR: Error
reading file at: file:/D:/AS/ORA10122MID/j2ee/home/HTTPPostService.wsdl:
D:\AS\ORA10122MID\j2ee\home\HTTPPostService.wsdl (The system cannot find the
file specified)". Make sure wsdl exists at that URL and is valid. </summary>
Thanks

this sounds strange, and I never heard of it ..
can you get us a step by step tutorial to see if our support can reproduce this ..
which version are you using?
thank you,

Can any one provide an web service technique that supports http post...?

hi,
i'm working with servlets. i need a webservice technique that supports http-post.
is it possible to work http-post using servlet & axis2 webservice....?

hi, if you are about to use axis2, consider trying JAXWS since its very fast to startup, it will then take care of everything what is beyond your business objects (so transforming in into XML etc) moreover, you're going to use web services, thus you ll be working with SOAP, which will wrap your business representation...
here a sample for a time -service. The Date object will automatically be trasinformed into appropriate xsd type by the axis2 engine
@WebService
public class Clock {
public Date getCurrentTime(){
return new Date();
}

How to send HTTP Post to URL (third party software) in JSP/JSPDynpage

Hello,
we want to integrate a third party application in our Portal Component (JSPDynpage using JSP and HTMLB). This third party component is called like this:
http://servername:port/cgi-bin/cgi.exe?request=map&format=html&swldy_ace=GDF&swldy_image_format=p n g&width=525&height=375
How can we do this in the JSP using HTMLB?
Thanks for your help.
Best regards,
Daniel

Hi Detlev,
thanks for your hint regarding the App. Integrator, but it seemn not to be what we want to do: We call a CGI and get a JEPG Image back as request.
Now we used the java.net.URLConnection to do the HTTP post in the JSPDynpage:
// send HTTP POST
try {
u = new URL("http://server/path/ourcgi.exe");
} catch(MalformedURLException ex) {
System.err.println("MalformedURLException");
// build query sting
String query = "request=plot&format=jpeg&template_name=......."
int cl = query.length();
try {
// open the connection and prepare it to POST
URLConnection uc = u.openConnection();
uc.setDoOutput(true);
uc.setDoInput(true);
uc.setAllowUserInteraction(false);
DataOutputStream dos = new DataOutputStream(uc.getOutputStream());
dos.writeBytes(query);
dos.close();
} catch ...
Best regards,
Daniel

Interesting! JDeveloper deploy to remote server uses HTTP POST

The documentation clearly mentions that the bpelc ant task only deploys to local server using a file copy. I was wondering how JDeveloper is able to deploy to remote servers. Turns out is just does a HTTP POST of multipart/form-data to upload the BPEL suitcase jar file. Given below is the trace of the POST. Of course, it is all proprietary for now and is not documented. Maybe Oracle can wrap this as a custom ant task?

If anyone is interested, I've created a custom ant taks to leverage this HTTP post for deploying the BPEL suitcase jar to remote servers. We didn't want to use FTP, as we'd have to change permissions on the files.
To do this, I've leveraged the oracle.tip.pc.infra.deploy.DeployRemote class. You just have to pass it the path the the jar, server url (http://host:port/deploy/deployProcess.jsp), domain, and password.
This seems to work fine for us.

Where does firefox cache the form parameters to be used in the reload event of a page that was the resposne of a HTTP POST request?

Suppose there is form in a web page and it submits data in HTTP POST method. After submitting the form, if I reload the page [either by the refresh button or back button; whichever applicable], firefox asks permission to resend the form data by saying "To display this page, Firefox must send information that will repeat any action...". Now if the user clicks on the resend, firefox resubmits the form data.
So where does firefox store this from data for such future resending/resubmission?
Is it possible to retrieve/manipulate those stored form data?

I thought I'd tried that, as tried lots of other things like encoding URL, but obviously not as this works.
Thanks for the quick reply.
We also have an issue with the people results not being able to be refined by Department or Job Title now we have connected the SP2010 farm to use the service applications from a SP2013 farm.

Using perl with the HTTP POST method to exchange XML with the Auth service

<?xml version="1.0" encoding="UTF-8"?>
<AuthContext version="1.0">
<Request authIdentifier="0">
<NewAuthContext orgName="dc=exampleorg,dc=com">
</NewAuthContext>
</Request>
</AuthContext>
Then I read the python post at http://swforum.sun.com/jive/thread.jspa?forumID=79&threadID=22370
and the error changed to Premature end of file.
this is the portion of perl that is getting the error:
use strict;
use LWP::UserAgent;
use HTTP::Request::Common;
my $browser = LWP::UserAgent->new(agent => 'xml client');
my $greeting = <<GREETING;
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<RequestSet vers="1.0" svcid="auth" reqid="1">
     <Request>
     <![CDATA[<?xml version="1.0" encoding="UTF-8"?>
     <AuthContext version="1.0">
          <Request authIdentifier="0">
               <NewAuthContext orgName="dc=belo,dc=com">
               </NewAuthContext>
          </Request>
     </AuthContext>]]></Request>
</RequestSet>
GREETING
my $response = $browser->request(POST 'http://idpoc1.test.belo.com/amserver/authservice',
                    Content_Type => 'text/xml',
                    Content     => [xmlRequest => $greeting]
print $response->error_as_HTML unless $response->is_success;

Your problem seems to lie in the build of the request. Here you use the "sample=$data" which will invalidate the XML itself. I've tested your code changing only the build of the Request and this works fine! Given an XML like this :
<?xml version="1.0" encoding="ISO-8859-1"?>
<data>
     <txnInfo sourcePartnerCode="6" txnDate="2005.09.08"/>
     <unitOfWorkInfo sourceTicketID="SourceTicket_1" diaryEntry="Diray_1" Status="Status_OK"/>
</data>
The Server Stub should look like this :
#!/usr/bin/perl
use XML::Simple;
use Data::Dumper;
print qq{Content-type: text/xml\n\n};
if($ENV{'REQUEST_METHOD'} eq "GET"){
     $my_data = $ENV{'QUERY_STRING'};
     print "jfghdsfjghsdg$my_data";
} else {
     $data_length = $ENV{'CONTENT_LENGTH'};
     $bytes_read = read(STDIN, $my_data, $data_length);
     print "$bytes_read, $my_data";
     $xml = new XML::Simple (KeyAttr=>[]);
     print "have passed XML::Simple creation\n";
     $data = $xml->XMLin("$my_data");
     print "i want to be here \n";
     $transcode=$data->{txnInfo}->{sourcePartnerCode};
     #print "$data->{txnInfo}->{sourcePartnerCode}";
     print $transcode;
     CASE: {
          ($transcode==6) && do {
               print "i am here";
               $lstmoddat=$data->{txnInfo}->{txnDate};
               $srctktid=$data->{unitOfWorkInfo}->{sourceTicketID};
               $actvtylogdesc=$data->{unitOfWorkInfo}->{diaryEntry};
               $status=$data->{unitOfWorkInfo}->{Status};
               $command='bop_cmd -f update1.frg "upd_stats("""Administrator""","""'.$srctktid.'""","""FIP""","""what is this???""")"';
               print "$lstmoddat $srctktid $status \n";
               print "$command";
               system("$command");
               print "i am done";
               last CASE;
And the client stub should look like this :
use LWP::UserAgent;
use HTTP::Request;
use IO;
#use XML::Writer;
my $ua = LWP::UserAgent->new(env_proxy => 1, keep_alive => 1, timeout => 30, );
open INPUT, "<AcceptIncident.xml";
my @greeting = <INPUT>; #-- Read file containing XML struct to send
print "Hello World\n";
my $data_to_send; #-- And build a string of it
foreach my $newItem (@greeting) {
     $data_to_send = "$data_to_send$newItem";
print "Sending \n";
my $head = HTTP::Headers->new(Content_Type => "text/xml", "ID" => "sample");
my $req = HTTP::Request->new('POST', 'http://matrix/cgi-bin/test1.pl', $head, "$data_to_send");
my $response = $ua->request($req);
print $response->as_string; Also you should make sure you have both HTTP::Request amd XML::Simple installed, orelse this will not work.
Hope this is of some help to you.

How to send a String to a Servlet using a HTTP POST

Well, I have designed a servlet that receives a HTTP POST, I was testing it using an HTML form to send (using POST) information, now, I have coded a Java App to send it a string, I don't know how to make the servlet recognize that info so it can make its work, I am posting both codes (Servlet & API) so anyone can guide me and tell me how and where to modify them
Servlet:
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.sql.*;
public class xmlwriter extends HttpServlet
public void service(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
ServletOutputStream salida = res.getOutputStream();
res.setContentType("text/HTML");
String cadena = req.getParameter("cadena");
File f1 = new File ("c:/salida.xml");
FileWriter out = new FileWriter(f1);
f1.createNewFile();
out.write(cadena);
out.close();
salida.println("OK");
Now, the JAVA API is:
import java.io.*;
import java.net.*;
public class HTTPSender {
public static void main(String[] args) throws Exception {
URL url1 = new URL
("http://localhost:8080/XMLSender/xmlwriter");//internal site
URLConnection UrlConnObj1 = url1.openConnection();
HttpURLConnection huc1 = (HttpURLConnection)UrlConnObj1;
huc1.setRequestMethod("POST");
huc1.setDoOutput(true);
huc1.setDoInput(true);
huc1.setUseCaches(false);
huc1.setDefaultUseCaches(false);
String cadena = ""
+ "<root>\n"
+ "<tlf>$TLF$</tlf>\n"
+ "<op>$OP$</op>\n"
+ "<sc>$SC$</sc>\n"
+ "<body>$BODY$</body>\n"
+ "</root>";
PrintWriter out = new PrintWriter(huc1.getOutputStream());
System.out.println("string="+cadena);
out.write(cadena);
out.close();
I'm a JAVA newbie, so, maybe I'm getting a bad idea of what I need to do, anyway, every (detailed) help is welcome. What my servlet should do (and it doesn't when I send the message through the API) is to write a file with the info received.

I'm not trying to send a string from a WEB Page, I'm tryring to send it using a JAVA program, I mean, using a HTTPSender, in fact, I already have made the code to do that:
import java.io.*;
import java.net.*;
public class HTTPSender {
public static void main(String[] args) throws Exception {
try {
String cadena = "Message to be written";
// Send data
URL url = new URL("http://localhost:8080/XMLSender/xmlwriter");
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(cadena);
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) {
And modified my servlet so it can receive anything:
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.sql.*;
public class xmlwriter extends HttpServlet
public void service(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
ServletOutputStream salida = res.getOutputStream();
res.setContentType("text/HTML");
String cadena = req.toString();
File f1 = new File ("c:/salida.xml");
FileWriter out = new FileWriter(f1);
f1.createNewFile();
out.write(cadena);
out.close();
salida.println("OK");
Now the problem is that, the servlet in fact DOES create the file, but....the file is empty, that means that no info is arriving to the servlet, why?, how should I send it then? I repeat FORGET about a Web Page Form, that is in the past and I don't need that.
