How to 'tunnel' requests/response with servlet?

Hallo!
I have the following problem.
Tomcat is used as ServletEngine. Here should work a servlet for authorization. The web application resides on another webserver.
After authorization all request go to Tomcat where a servlet should get (via HTTP) the HTML-pages from the other webserver and sends them to the client. The customer wants to act the Tomcat as Server to the client and as client to the other webserver. For me it seems to be some kind of proxy functionality.
How can I achieve this?
Kind regards
Jochen

Hi,
I am currently writing almost the same thing. And I have a partial success with something like ProxyServlet. What it does:
1. creates a URL object
2. creates HttpURLConnection through the URL
3. copies servlet's request parameters to the HttpURLConnection's request
4. copies the HttpURLConnection's response to the servlet's response
It works, but it is very - very slow.
I am currently struggling with the Keep-Alive feature in HTTP 1.1 that the remote server sends. If I copy that header onto the response, the client sends another request to the same channel, that is mean while broken - the servet is used only by one to one.
I am trying to find something like URL Connection pool, but still I am not successful. I am going to try not to trasfer the Keep-Alive headers to the client - perhaps this sort of downgrading Http 1.1 to 1.0 will limit the timeout delays ...
Did you succeed in your work ?

How to redirect request to a servlet on another server/context

Hi
I want to redirect a request came to a servlet to another servlet on another server or atlest different context on same server.
Thanks in advance,
--Nagesh

Thanks but, now after rediriceting the request I am
not getting any ServletInputStream. Getting rintime
error as NoClassDefinitionFoundError :
ServletInputStream.That's indicative of a problem with your classpath settings.
DO I have to do anything the JSP
(which submitted the request to first servlet) after
redirecting?Nops, you shouldnt do anything after sendredirect(). The response is committed after using this method.

How to deploy an app with servlet and background processing

i have a servlet with background processing. it has to run 24 hours a day.
but i have problem with shutdown (after 1-2 hours without user action). [9iAS 9.0.3.0, windows 2000]
i created for application seperate OC4J (in the EM) and i deployed it there. first time as war file, later as ear file (because there is possible to re-deploy only ear file).
but it seems that the servlets are not designated to run as a uninterruptible task.
the question is: how to deploy such (servlet + uninterruptible background processing) application in the 9iAS?
a) everything in the OC4J (then how to disable shutdown?)
b) servlet in the OC4J. where (and how) to install the rest of application?
b1) servlet in the OC4J + rmi/soap/... + standalone server?
what is the standard in the oracle world :) ?
thanks

How to implement request/response domain in JMS

hi friends,
I need help regarding implementing request/response domain
in jms.please help me.

See the TopicRequestor and QueueRequestor helper classes in the JMS API.
FWIW there's a POJO based request/response implementation using JMS here...
http://lingo.codehaus.org
you might find the source code useful as it does efficient request/response in a highly concurrent way using JMS under the covers.

Simulate multiple request / response with a HTTP URL

I need to communicate with a servlet. In the first request, the user gets authenticated and a connection is created. Now I need to use this connection to send further requests since all requests undergo an authentication check.
However, when I try to implement the same, the second time I write to the output stream of the connection, I get the following exception:
java.net.ProtocolException: Cannot write output after reading input.
Please help! I need to create an application which communicates with this Servlet in the specified way

Now I need to use this connection to send
further requests since all requests undergo an
authentication check.That's not how HTTP works. For each request, you have
to make a new connection. And as for authentication,
it's perfectly feasible for you to do the
authentication for every single request, but (at
least in the case of basic authentication) browsers
tend to send an Authorization header once they have
done the original authentication dialogue. You could
do that too.Also, underneath it all, HTTP 1.1 tries to maintain a socket connection so you don't have that overhead to deal with each time. But as DrClap says, you need to use fresh HTTP instances each time and set the appropriate session/authentication headers.

How to use EAServer Jaguar with servlets?

I have a web application that I have done using Tomcat and now need to run it with EAServers Jaguar. I am currently going through EAServer 5.2 documentation and the tutorial for creating a simple java application seems rather tedious ( have to use EAServers manager to create packages and components etc).
Can anyone out there with experience tell me if going through the entire EAServer documentation will help me configure the server for servlets n jsp or is there an easier way to do things? Is it possible for me to just export my whole Web Application folder to some location in EAServer directories and run it like we do in Tomcat?
I cant seem to find much help or tutorials on the net... Thanks for any help!!

Ive found a few sources that uses PowerJ IDE to create WAR files to deploy in EAServers Manager. I tried creating a HelloWorld WAR without any IDE but cant seem to deploy it in EAServer Manager.
Can anyone give some advice??

How can my applet communicate with servlet via HTTPS?

hi all,
I'm using jdk1.4.2_03. Tomcat 4.1.27/29.
My applet used to communicate to serlvet/JSP via http protocol. However, I wish to apply SSL in my tomcat standalone. Is there any implication towards my existing applet to servlet codes?
For example,
URL servletURL = new URL("http://www.myhost.com/Shopping");
// open connection between applet and servlet
URLConnection servletConnection = servletURL.openConnection();
servletConnection.setDoOutput(true); // allow connection do output
servletConnection.setDoInput(true); // allow connection do input
servletConnection.setUseCaches(false);
servletConnection.setRequestProperty("Content-Type", "application/octet-stream");
ObjectInputStream input = new ObjectInputStream(servletConnection.getInputStream());
resultset = (Vector)input.readObject(); //get Object from Servlet
input.close();

I never used it though, you can check for some code here:

How to use Oracle Procedures with Servlet page

Hi all
I'm working on Servlet pages and I need to insert and select some records from Oracle database but it has to be done by calling some already written Procedures. I've never really used them before so I'm little lost. I know where the queries are used it'll be Procedures but what is the syntax for it.Can anyone put me in right direction please.

Request Response Receive Port and Solicit Response Send Port

Can anyone give me some idea how to bind Request Response Receive Port and Solicit Response Send Port with each other through TCP/IP adapter ??

The binding of a Receive and Send Port has nothing to with the choice of Adapter.
1) There is no out-of-the-box TCP/IP Adapter for BizTalk, but several 3rd. Party Adapters has been made, along with this one in CodePlex: http://tcpipbz2010.codeplex.com/
2) Most people will use an Orchestration for binding a SR Send Port to a RR Receive Port. This may not be necessary though. All you need to do is have your Send Port subscribe to your Receive Port (by setting the Filter on the Send Port to "BTS.ReceivePortName
== [The name of your Receive Port]". In this case, internal correlation will make sure that the response is routed back to the Receive Port.

Swings with servlets

Hi,
how we can use swings with servlets or jsps.
or
how we can display the browser in the swings.
please give me a valid answer with examples.

Hi,
Your question is not clear... are you trying to display HTML using swing components or are you trying to use swing in a server-side application?
Some Swing components (e.g. JLabel) natively support simple html, so:
JLabel lbl = new JLabel("<html>hello world</html>");would result in a JLabel that looks with the word "world" in bold. If you need also frames, css and javascript support - you'll need to reach for a 3^rd^ party library, I'm afraid.
As for using swing in servers, look at this article:
http://today.java.net/pub/a/today/2006/04/20/bringing-swing-to-the-web.html
If you meant neither, please explain more.
Hope this helps, though.

Using forward(request, response) in Java Servlet

Hi
I need help on how to use the forward() method in a java servlet passing a List object and riderecting to another jsp.
when I use the following code;
request.getRequestDispatcher(path).forward(request, response);
I'm getting this message:
Content modified /content...

Referer
Thanks,

Looking at your traces seems like you are forwarding during POST. Seems like issue with your component implementation missing with POST & proxy scripts. Please eloborate more on the exact steps you are following. Alternatively See if this helps.
org.apache.sling.api.wrappers.SlingHttpServletRequestWrapper req =
new org.apache.sling.api.wrappers.SlingHttpServletRequestWrapper(slingRequest) {
public String getMethod() {
return "GET";
String path = "/content/.../test.html";
javax.servlet.RequestDispatcher dispatcher = slingRequest.getRequestDispatcher(path);
dispatcher.include(req, slingResponse);

How do i track clicks with jsp/servlets?

I would like to know how to imitate the click of link in JSP or serlvet, in order to track clicks.
I have pages with links containing tel protocol URIs like this:
Click here to listen!
I want to replace the above with something like this:
Click here to listen!
And have call_tracking.jsp do its tracking stuff and then spawn a phone call, just like the first example does. I do not want to bother the user with another page, hence the need to accomplish the click action programmatically. I presume this feat is achievable via Response header magic, I just don't know the right incantation ;-)
Thanks

You should create a servlet to track the links, let´s say LinkTracker. Here I have an example for you. Each link calls a servlet and pass the url as a parameter.
<html>
<head>
 <title>Some Links Tracked by the LinkTracker Servlet</title>
</head>
<body>
Some good links for you. Each link is directed
through the LinkTracker Servlet. Click on a few and visit
the <a href="LinkTracker">LinkTracker Servlet</a>.
<ul>
 <li><a href="LinkTracker?link=http://www.google.com">
 Google Site</a></li>
 <li><a href="LinkTracker?link=http://www.yahoo.com">
 Yahoo site</a></li>
 <li><a href="LinkTracker?link=http://java.sun.com">
 Sun Microsystems</a></li>
</ul>
</body>
</html>And here the code to LinkTracker servlet
public class LinkTracker extends HttpServlet {
static private Hashtable links = new Hashtable();
String tstamp;
public LinkTracker() {
 tstamp = new Date().toString();
public void doGet(HttpServletRequest request,
 HttpServletResponse response)
 throws IOException, ServletException {
 String link = request.getParameter("link");
 if (link != null && !link.equals("")) {
 synchronized (links){
 Integer count = (Integer) links.get(link);
 if (count == null) {
 links.put(link, new Integer(1));
 else {
 links.put(link, new Integer(1+count.intValue()));
 //here the servlet redirect the client to the link he clicked
 response.sendRedirect(link);
 else {
 response.setContentType("text/html");
 PrintWriter out = response.getWriter();
 request.getSession();
 out.println("<html>");
 out.println("<head>");
 out.println("<title>Links Tracker Servlet</title>");
 out.println("</head>");
 out.println("<body>");
 out.println("Links Tracked Since");
 out.println(tstamp+":");
 if (links.size() != 0) {
 Enumeration enum = links.keys();
 while (enum.hasMoreElements()) {
 String key = (String)enum.nextElement();
 int count = ((Integer)links.get(key)).intValue();
 out.println(key+" : "+count+" visits ");
 else {
 out.println("No links have been tracked! ");
 out.println("</body>");
 out.println("</html>");
public void doPost(HttpServletRequest request,
 HttpServletResponse response)
 throws IOException, ServletException {
 doGet(request, response);

How to Modify Data in a Servlet Response

Hi..
I have a servlet that upon receving an http request from client sends some data to the client browser, but i want to modify the data that is being sent to the client and resend it somehow (like its a kind of bypassing...without sending the original data..i want to modify the data and send the response ON THE FLY.
Any ideas of suggestions how to do it, if some one of you has already done it then pls do send some code snippet.
Thanx in advance
mark.

Aha... now the truth comes out. You asked how to do it, but your secret question was that you were already doing it and you were having some problems. It's generally just better to come out and ask the question, even though it may be embarrassing that what you did isn't working.
To me, what you did sounds like a perfectly good method, except that writing the data to a temp file is going to run you into problems as soon as you get two requests at about the same time. I would do that in memory instead (write to a ByteArrayOutputStream, get the resulting array of bytes, modify it, and write the end result out to the servet response's output stream).
The problem you describe, though, is probably caused because the browsers are caching requests to your servlet. Do you have something like this code in your servlet that tells the browsers not to cache it?response.setHeader("Cache-Control", "no-cache");
response.setHeader("Pragma", "no-cache");

How can I know whether the Servlet is sending a response!!!

Hello,
My question is this :
How do I know whether that server outputstream is sending me a response or not?
I have opened the Client InputStream to recieve a response from a servlet,but how
can i be sure that i will receive a response from the servlet?
I cud be waiting for an 15 expecting a response but havent received one..
Is there any way to check whether the servlet is sending me a response?
The reason I am asking is this.
I have written a Java Client that connects to a servlet.It has to wait for a
response from the servlet.It will wait for 5 seconds and if this doesnt recieve
a response,it will return back else it will display the response.
I have set a timer on my client for 5 seconds and a timer on the servlet for 15 seconds.
Essentially,when the client connects,the servlet response is held for 15 seconds
and the client tries for 5 seconds.
But the client is unable to exit without a response.The response comes back in 15 seconds.
The client shud have the message 'Connection Timed Out' after 5 seconds.
This means there is an error somewhere.
As the response takes 15 seconds,the client shudnt recieve one.
So,is there a way I can block the servlet response?
I am using threads and Inner classes for the timer purposes..
Please can any one help me?

sMess = dis.readUTF();
System.out.println("Received from Client: " + sMess);
// Send response back after 15 seconds Only.
try {
for(int i=0;i<15;i++)
System.out.println(i);
DataOutputStream dos = new DataOutputStream(response.getOutputStream());
String sResponse = "Hello Client...This is server sending response";
dos.writeUTF(sResponse);
Thread.sleep(1000);
}catch(InterruptedException e){}

I don't know whether you solve your problem or not! Anyway, I have the same problem. The program hangs when getInputStream is called.
DataInputStream dis = new DataInputStream(request.getInputStream());
If you have the answer, please let me know. Thanks!!
