How to send a request and get a response through xml files?

This is the code that works for me. Hope you find it useful.
     public static String sendHttpGetRequest(String endpoint, String requestParameters){
          String result = null;
          // Send a GET request to the servlet
          try{
               // Send data
               String urlStr = endpoint;
               if (requestParameters != null && requestParameters.length () > 0){
                    urlStr += "?" + requestParameters;
               URL url = new URL(urlStr);
               HttpURLConnection conn = (HttpURLConnection) url.openConnection();

Best Practices Question: How to send error message to SSHR web page.

Best Practices Question: How to send error message to SSHR web page from custom PL\SQL procedure called by SSHR workflow.
For the Manager Self-Service application we’ve copied various workflows which were modified to meet business needs. Part of this exercise was creating custom PL\SQL Package Procedures that would gather details on the WF using them on custom notification sent by the WF.
What I’m looking for is if/when the PL\SQL procedure errors, how does one send an failure message back and display it on the SS Page?
Writing information into a log or table at the database level works for trouble-shooting, but we’re looking for something that will provide the end-user with an intelligent message that the workflow has failed.
Thanks ahead of time for your responses.

We have implemented the same kind of requirement long back.
We have defined our PL/SQL procedures with two OUT parameters
1) Result Type (S:Success, E:Error)
2) Result Message
In the PL/SQL procedure we always use below construct when we want to raise any message
hr_utility.set_message(APPL_NO, 'FND_MESSAGE_NAME');
hr_utility.raise_error;
In Exception block we write below( in successful case we just set the p_result_flag := 'S';)
EXCEPTION
WHEN APP_EXCEPTION.APPLICATION_EXCEPTION THEN
p_result_flag := 'E';
p_result_message := hr_utility.get_message;
WHEN OTHERS THEN
p_result_flag := 'E';
p_result_message := hr_utility.get_message;
fnd_message.set_name('PER','FFU10_GENERAL_ORACLE_ERROR');
fnd_message.set_token('2',substr(sqlerrm,1,200));
fnd_msg_pub.add;
p_result_message := fnd_msg_pub.get_detail;
After executing the PL/SQL in java
We have written some thing similar to
orclStmt.execute();
OAExceptionUtils.checkErrors (txn);
String resultFlag = orclStmt.getString(provide the resultflag bind no);
if ("E".equalsIgnoreCase(resultFlag)){
String resultMessage = orclStmt.getString(provide the resultMessage bind no);
orclStmt.close();
throw new OAException(resultMessage, OAException.ERROR);
It safely shows the message to the user with all the data in the page.
We have been using this construct for a long time for all our projects. They are all working as expected.

Hi
I agree usage of HttpClient is a better and a simple method.
But If your Application Requirements are Simple you may go by using URL & URLconnection Objects in java.net package.
Just to Add In You Can Checkout the links given below to have a better understanding of how the communication works...
The Example APPLET code:

Hi,
Seems to be a problem with your GUI as the dump MESSAGE_TYPE_X is generally related to GUI. Use some higher version of GUI than the existing one.
Also Updates are not active in your system. Use transaction SM13 to check whether updates are active or not. If not then use transaction SM14 to turn on the updates.

How to send a file to a web service

I am developing a web service application which needs to accept a CAD model as input. Would any one tell me how to send a file from a client application to service provider.
thanks in advance

You can use mime encoding inside your SOAP request, something like this:
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<data>
<file>
<name>filename.zip</name>
<content>FVberI0XlJincJEGmcbVyMOGpdWGl1bYB2r1y2vYicHqq0WYuergigzYB20GvMLZ

</content>
</file>
</data>
</soap:Body>
</soap:Envelope>This can even be accomplished from within Pl/Sql. Otherwise you can use the WS-Attachment feature which is (I think) not yet supported by Oracle.

How to send authentication information to SOAP Web Service using MATE framework

Hi,
Can anyone please tell me how to pass authentication info (such as user name & password) while calling a webservice using MATE's webserviceinvoker? the SOAP web service expects authentication info in the header.
Thanks in advance..

HI Swayam,
First of all you should tell us what blogs you have seen to avoid you to repeat information that you already know.
we want to avoid setting up SLD configuration for sender system because sender system is just consuming web service .
This is not necessary,
Please let me know the ways we can configure . I did understand we can publish and register the WSDL from Service interface ,but was not clear on over all scenario .
Do you have your ECC webservice available via SOAManager?, you only to access it via soap receiver in SAP PI.
To publish, you need to publish only the sender SOAP, when you register there the sender soap your partner could access there to get the WSDL (Publish services from PI 7.1 to the Service Registry). Also you can generate directly the wsdl (Display WSDL - Integration Directory - SAP Library), what do you want?

How to send a request to servlet from a java client.

I called a servlet from java client using URL object.
I could establish a connection with server and display
the content(like req.getservername etc.,)
of servlet on client side(DOS prompt).
My question is how do i send a request to servlet from the client.
let me say, i have to send a value as 10 to servlet and do some processing
( like 10*2 = 20) display the output (20) on client side..
It will be appreciated if u can mention the syntax...

just add the query string to the url you use to create the URL object from.

How to send SOAP request by HTTP POST?

I want to access a SOAP webservice using mx.rpc.soap.mxml.WebService.
Following is my code:
<mx:WebService id="miner_service" wsdl="http://localhost:8080"> <mx:operation name="hello" result="echoResultHandler(event);"></mx:operation></mx:WebService>
When debugging with that, I got such error message:
[Fault] exception, information=[RPC Fault faultString="HTTP request error" faultCode="Server.Error.Request" faultDetail="Unable to load WSDL. If currently online, please verify the URI and/or format of the WSDL (http://localhost:8080)"]
Then I use Fiddler try to capture the response returned by server, it's like this:
Error responseError code 501. Message: Unsupported method ('GET'). Error code explanation: 501 = Server does not support this operation.
But when I use python to send SOAP request by HTTP POST, the server will return correct response.
So how can I send SOAP request by HTTP POST?
(I tried <mx:WebService wsdl="http://localhost:8080" method="POST">, but no luck..)

Sorry for my late reply..
There's no WSDL for that SOAP service

How to send two request in the same connection with HttpURLConnection?

As the title, I want to send two or more requests in the same connection with HttpsURLConnection..I wish all requests are in the same session.
My code is as following:
package test1;
//import javax.net.ssl.*;
import java.net.*;
import java.io.*;
public class httptest {
public httptest() {
public void test() {
HttpURLConnection uc = null;
String urlStr="";
urlStr="http://172.16.245.151/test/page1.jsp";
try {
URL u = new URL(urlStr);
uc = (HttpURLConnection) u.openConnection();
uc.setRequestMethod("GET");
uc.setDoOutput(true);
// uc.connect();
OutputStream out = uc.getOutputStream();
out.flush();
out.close();
catch (Exception ex) {
System.out.println(ex.getMessage());
public static void main(String[] args) {
httptest tt = new httptest();
tt.test();
The sample class just can send a request..Now we think of the sentence :uc = (HttpURLConnection) u.openConnection();
Obviousely, a HttpURLConnection can just have a Object of the Class URL, and the Class URL have no setURL mothed. So I can't use a HttpURLConnection to send two request.
I just want the HttpURLConnect is the same to IE...Do you understand what I mean?
Any helps will be appreciated...

How to set Maxmimum header length in Web Server. It creates a problem

I have setup Sun webserver ahead of Glassfish Application server.
Now when i send a request having length 17000 as POST request , my application does nt receive the whole request data.
If i make request direct to Application server , app server servs the request properly. but when i send the request to websever which diverts the request to app server only , it creates some manipulation with the data sent in the POSt request.
Can any one please guide me what to do.?
Thanks in advance/

I would first try to take GF's loadbalancer plugin out of the configuration and instead use Web Server 7.0's integrated reverse-proxy functionality to pass the requests to your backend AppServer. This will tell you if the problem is in the lbplugin or in some other component in WS 7.0.
The following briefly describes what you might have to do in order to use the integrated reverse-proxy functionality in WS7 instead of GF's lbplugin.
Delete/comment out the following lines in your magnus.conf file:
Init fn="load-modules" shlib="D:/Sun/WebServer7/plugins/lbplugin/bin/passthrough.dll" funcs="init-passthrough,service-passthrough,name-trans-passthrough" Thread="no"
Init fn="init-passthrough"GF's lbplugin installer has incorrectly added a duplicate entry for j2eeplugin in your magnus.conf. Delete this line too:
Init fn="load-modules" shlib="D:/Sun/WebServer7/lib/j2eeplugin.dll" shlib_flags="(global|now)"Replace the following line in obj.conf
NameTrans fn="name-trans-passthrough" name="lbplugin" config-file="D:/Sun/WebServer7/https-01HW151407.India.TCS.com/config/loadbalancer.xml"with
NameTrans fn="map" from="/" name="reverse-proxy-/" to="http:/"Add the following Objects to the bottom of your obj.conf file:
<Object name="reverse-proxy-/">
Route fn="set-origin-server" server="http://appserver.host.com:8080"
</Object>
<Object ppath="http:*">
Service fn="proxy-retrieve" method="*"
</Object>Replace appserver.host.com and 8080 with the appropriate hostname and port number of your GF installation.
More info on setting up WS7's reverse proxy can be found here:

How to set up a FTP and web server and integrate with DMM 5.2

Hi All ...
I need to set up a external server only for content publishing to reduce the overhead of the DMM server .
can anyone guide me on how to set up the external server and intergrate it with the DMM 5.2
Thanks

semuthu,
Notes from the Release Notes:
Compatibility Limitations with Microsoft Internet Information Server (IIS)
DMPs that use firmware release 5.2 are compatible with only one version of Microsoft Internet Information Server.
That supported version is IIS 6.0 for Windows 2003 Enterprise. If you do not have the supported IIS version but
want your DMPs to retrieve assets from a webserver, we recommend that you use Apache instead of IIS.
I would suggest using Apache instead of IIS for the webserver service. IIS can be used as FTP if needed.
There are plenty of Documents on the Web about setting up Apache and FTP for servers.
Using Apache with Microsoft Windows

Quick HOWTO : Ch20 : The Apache Web Server
http://www.linuxhomenetworking.com/wiki/index.php/Quick_HOWTO_:_Ch20_:_The_Apache_Web_Server
Once the Webserver is setup and operational. You simply store your media content on the Webserver
and then have your DMS assets in the media library use an external URL address for its location.
If you want to use external server for other features in the DMM, you can can see how to configure

How to publish a servlet class to web server?

background:
web server: tomcat apache 4
context path: webapp\test\
servlet path: webapp\test\WEB-INF
servlet name: HelloWorld.class
i tried to placed the servlet class file to above servlet path,
but i can't invoke the servlet by http://localhost:8080/test/HelloWorld
what should i do in order to invoke the servlet at browser?
Is a web.xml necessary a must to provided a mapping between request name and actual class name?

First of all you need a *.war structure which look like this
/app-name
/app-name/WEB-INF/
/app-name/WEB-INF/lib
/app-name/WEB-INF/classes
When you have created this structure you add your servlet (HelloWorld.class) in the classes directory (Create the package structure first).
When this is done you need to map the servlet to a given uri which is done in the web.xml. An example is found below:
<servlet>
<servlet-name>hello</servlet-name>
<servlet-class>package.HelloWorld</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>hello</servlet-name>
<url-pattern>/hello/*</url-pattern>
</servlet-mapping>
Hopefully this will help :-)
best regards
Stig
