[Help] Sending HTTP requests
i was to check whether the web system created can handle a certain number of requests.. is there a possibility of sending a certain number of requests per second using a java?
is there any libraries i have to import?

would you happen to have to link to show me how to use Virtual users??I don't remember any off my head, but you should be able to google it.
also when URLConnection is used does it create session as well? cuz i when i sent request using URLConnection and check tomcat manager to see how many session had been created it showed none.. but when i used wget or tried going to the link via a different browser it created a session..You will need to write additional code to manage session cookies, but JMeter will let you do that easily.

Problem in sending HTTP request to the server.
Hi,
i dveloped an ant script for sar deployment.
i deployed a sar to my local soa server with ant script. it got deployed succesfully..
but when i try to deploy to a remote server, getting the below error..

Please, help me with two problems I have to solve. I'm beginner in Java.
1. Create a simple program that sends http request for index.html and shows the result.
2. Create a simple program that gets the list of messages from a give mailbox over POP3 (server, username, pass - give as params).
Thank you!But I think that I need request like this:
GET /index.html HTTP/1.1
Host: www.example.com
and as a result (maybe) something like this:
HTTP/1.1 200 OK
Date: Mon, 23 May 2005 22:38:34 GMT
Server: Apache/1.3.27 (Unix) (Red-Hat/Linux)
Last-Modified: Wed, 08 Jan 2003 23:11:55 GMT
Etag: "3f80f-1b6-3e1cb03b"
Accept-Ranges: bytes
Content-Length: 438
Connection: close
Content-Type: text/html; charset=UTF-8Well, under the covers, that will be what you have.
It says "simple program" - do you think you are expected to connect your own socket and send a request you build from scratch yourself? Unlikely.
As for the response - you can probably skip the headers and just display the content that follows (in your example 438 bytes). -
ExecutorService creating tasks to send HTTP requests - time out
In my java application, I have introduced ExecutorService to create tasks. The tasks consist of sending HTTP requests to an application server, to process transactions. The ExecutorService will process about 1000 requests.
The executor process the transactions and terminates OK, but some of the transactions timed out (before introducing ExecutorService, I was just sending one transaction at time, all the transactions were processed OK; but, it was taking a long time to process).
See the code below.
private ExecutorService threadExecutor;
threadExecutor = Executors.newFixedThreadPool(30);
threadExecutor.execute(transaction);
try
//Shutting down the ThreadExecutor
threadExecutor.shutdown();
threadExecutor.awaitTermination(30, TimeUnit.SECONDS);
threadExecutor.shutdownNow();
catch (InterruptedException e)
System.out.println("ERROR - cannot shutdown the ThreadExecutor - exception is: " + e);
Is this the best way to implement this use case?
Thank you.From the above code, it seems like you are starting only a single transaction in a thread pool. Or does the transaction object you pass to the threadExecutor spawn more tasks for the executor?
If you are indeed still making all HTTP requests from the single transaction object, then yes, it will 'time-out' after 30 seconds, since the ExecutorService was instructed to stop its threads after that period of time.
Your description of the use case is actually a good example of the usage of an ExecutorService, since it is faster to do 1000 HTTP requests in parallel than it is to do them sequentially.
Consider this:
ExecutorService threadExecutor = Executors.newFixedThreadPool(30);
for (int i = 0; i < 1000; i++)
threadExecutor.execute(new Transaction());
try
threadExecutor.shutdown();
threadExecutor.awaitTermination(30, TimeUnit.SECONDS);
threadExecutor.shutdownNow();
catch (InterruptedException e)
// Ignore
}This will spawn 1000 transactions that will execute in parallel, with max. 30 running at any single point in time. Any transactions still not executed after 30 seconds will be terminated.
Hope this helps.

I have a Java program that creates a url from a String, then uses the openConnection method of URLConnection to send the request to a web server. The exact same Url string works fine from my browser, but the Java program throws a java.io.FileNotFoundException. Other url's work OK.
Any pointers as to what could cause this are appreciated.See if anything in http://forum.java.sun.com/thread.jsp?forum=4&thread=135019 helps you.

Help: Sending HTTPService request using POST to a php script
Hello all,
I need help in learning the proper method of communicating to php scripts from flex 3. I am very new to flex 3, php and web development. Thanks!
What I am trying to do is as follows:
1. User drags and drops a few items in a list control
2. user clicks a button to send these keywords to server php script
3. server will form a query based on the words sent and retrieve records and send them back
Here is what I have done so far:
1. When I send a request to server without any parameters, I amable to receive the request and query the database and send results in xml format
current issues I am facing:
1. I am gathering the list of entries in list control as follows:
<*** this function is callled when user decides to send request to server ***>private function startsearch():void {
var i:int;
var myAC:ArrayCollection = ArrayCollection(SelCtypes_id.dataProvider);
var nct:XML = new XML("<contenttypes></contenttypes>");
// add contenttype child now
for (i = 0; i<myAC.length; i++) {
nct.appendChild(XML(<contenttype>{myAC[i].toString()}</contenttype>));
var params:Object = new Object();
params.contenttypes = nct.toXMLString();
getsearchresults.send(params);
<*** my http service entry****>
<mx:HTTPService id="getsearchresults"
method="post"
url="http://localhost/search_xml.php"
result="handlesearchresultsXml(event)"
contentType="application/xml" />
This is what I see in flex debugger just when the request is sent out:
-> just before gersearchresults.send(params) call:
params.contenttypes = "<contenttypes>
<contenttype>AVI</contenttype>
<contenttype>SWF</contenttype>
</contenttypes>"
<*** within the HTTPrequest send function, I see th following in debugger ***>
message.contentType="application/xml"
message.body = paramsToSend shows "<contenttypes><contenttypes>
<contenttype>AVI</contenttype>
<contenttype>SWF</contenttype>
</contenttypes></contenttypes>"
This looks like my XML object is again formatted by an out <contenttypes> tag and the string is converted to be HTML safe (i.e. <, > notation).
It looks like I am not doing something right with my params formation to XML and HTTPservice is reformatting it to be some form of XML (I do not know XML well either :-)
My questions:
1. What am I doing wrong?
2. If there is a good example where I can send multiple parameters from flex client to php server and get data back where the request parameters will beof the form...
<query>
<type1>
<type1val>value1</type1val>
<type1val>value2</type1val>
</type1>
<type2>
<type2val>value3</type2val>
<type2val>value4</type2val>
</type2>
</query>

I removed some parts of the code so it's easier to read, if you can help me. I'm trying to populate a datagrid with info from a database, according to the alias I choose in the ComboBox. I get the error when I pick an alias from the ComboBox.

Apache HA: Probe sends HTTP request to HTTPS port
Hello,
i have a Sun 3.2 Cluster and the Apache HA module configured as described in the documentation. Works fine, except of the probe sending a HTTP request to the HTTPS port - this causes every minute an error log entry which is annoying. The log file runs full of these "HTTP spoken on HTTPS port" messages.
I have already tried to set the Monitor_Uri_List parameter to http://servername:80/ but this does not help. Has anyone a solution to this problem? Can I just re-create the apache HA module and leave out the '44/tcp' in the Port_list parameter?
Thanks for help,
marc.It doesnt matter where they are, you just need to set up the two virtual hosts as per my example. The fact that the domains are the same with/without ssl doesnt change my example above.
So, you need to set up one ssl host for the domain sharpie.pen.com, and a non-ssl host for the domain sharpie.pen.com. If you want bic.pen.com to have the same behavior you will need another pair for that.
Apache must have a virtual host to respond to a port/domain combination.
The reason I suggested a re-write rule of the form I did was to ensure that if someone went to:
http://sharpie.pen.com/webmail/login.php (for instance)
they would be redirected to
httpS://sharpie.pen.com/webmail/login.php
rather than the root of the domain.
Does this help?

File.upload on Air SDK for iOS devices failed to send http request to server.
I am trying to use ActionScript's File.upload to upload a file on Air SDK for iOS8 environment, but the File.upload does not work properly. No handler about the file upload is executed after File.upload is invoked, and no exception is caught. When I check the network traffic of the server side, I found that no http request even hit the server after File.upload is executed. The code snippet here is very simple.
private var file:File;
private var dir:File;
//This method is executed to create a file and upload it when the Upload Button is pressed.
protected function OnUploadButtonPressed(event:MouseEvent):void{
var str:String = 'This is test';
var imageBytes:ByteArray = new ByteArray();
for ( var i:int = 0; i < str.length; i++ ) {
imageBytes.writeByte( str.charCodeAt(i) );
try{
dir = File.applicationStorageDirectory
var now:Date = new Date();
var filename:String = "test" + now.seconds + now.milliseconds + ".txt";
file = dir.resolvePath( filename );
var stream:FileStream = new FileStream();
stream.open( file, FileMode.WRITE );
stream.writeBytes( imageBytes );
stream.close();
file.addEventListener( Event.COMPLETE, uploadComplete );
file.addEventListener( IOErrorEvent.IO_ERROR, ioError );
file.addEventListener( SecurityErrorEvent.SECURITY_ERROR, securityError );
file.addEventListener(ErrorEvent.ERROR, someError);
file.addEventListener(ProgressEvent.PROGRESS, onProgress);
file.upload( new URLRequest("http://10.60.99.31/MyPath/fileUploadTest.do"));//This line does not work. No handler is executed. No http request hit the server side.
} catch( e:Error ) {
trace( e );
//Complete Handler
private function uploadComplete( event:Event ):void
trace( "Upload successful." );
//IOError handler
private function ioError( error:IOErrorEvent ):void
trace( "Upload failed: " + error.text );
//SecurityError handler
private function securityError(error:SecurityErrorEvent):void{
trace( "Security error:" + error.text );
//Other handler
private function someError(error:ErrorEvent):void{
trace("some error" + error.text);
//Progress handler
private function onProgress(event:ProgressEvent):void{
trace("progressHandler");
When executed on Air Simulator, it works fine as expected, and the file is successfully uploaded to the server. But When executed on iOS devices(in my case, iPad), as I explain early, no handler about the file upload is executed, and no the http request even hit the server. So I think the problem may be in the client side. It seems that the Air SDK for iOS just failed to send the http request for some reason.
To make my problem more clear, I list my environment below:
Development Environment: Windows7 (64bit) / Mac os 10.9.4 (Tested on OS platforms.)
IDE: Flash Builder 4.7
Air SDK: 3.8 / 16.0.0 (After I updated to the lastest Air SDK 16.0.0 , the problem still exists.)
Application Server: Tomcat7 + Spring
Target OS: iOS 8
I have been struggling for this for days. So I really appreciate it if anyone has any idea about this.
Thanks in advance.Hi bluewindice ,
As you have quoted ( ActionScript's File.upload does not work on Air SDK for iOS devices ) , this issue has been replicated at our end, and our team will be working on it.
Thanks,

In ActionScript 2.0 , How can I send HTTP request and get the response in JSON format.
I am using ActionScript 2.0 for my app development. I have checked XML and LoadVars class. These classes by default send/receive data either in XML or name/value pair format. I want to send data in JSON format and receive the response in JSON format. How can I achieve this behavior using AS2.0. I have noticed that AS3.0 has the capabilities to do so. My client platform doesn't support AS3.0. Can anybody suggest a way to achieve this?
Thanks in Advance.Atlast I am able to find the solution for this problem. In the end solutioin is very simple.
Following steps will help in sending request in JSON format.
1. extend LoadVars class
2. override toString method. (It should return JSON format )
3. Use subclass to send the request. -
Guys,
i need to implement a program that will send request to the server and recieve the http response from the server.
Some of information will attached in the http response from the server.
My application must able to catch out this info in the http response header.
I had use the httpClient jar to send the request and i able to recieve http response 200 or 400 only from the server.
Can any one of you give me some idea on how to retrieve the attached info in the response header?
Thanks in advance.See http://jakarta.apache.org/commons/httpclient/apidocs/index.html

Problems sending HTTP request to PI
In order to receiver a HTTP request from HTTP server onto PI, what things needs to be defined in PI?
there is an HTTP application which can connect to other PI server in my environment without any issues, but when I point it to intended PI server, it is throwing exceptions. Where am I doing wrong? do I need to create a some RFC destination for this?Hello!
Since you are talking about "PI" I believe you're using 7.1X.
From this, check this link: http://help.sap.com/saphelp_nwpi71/helpdata/EN/44/bcd15381f456a1e10000000a1553f6/frameset.htm
Also, when you go to the INTEGRATION_DIRECTORY_HMI, the result
should be 500 "Internal Server Error" and not the 200 Ok that we're used to
Hope it helps!
