Communicating with Servlets....

hi!
Wat are all the different ways in which the JSP used to communicate with Servlet?
Thanx,
Rgds,
Sasi

Jsp page communication with Servlets....
web.xml -- Servlets loaded during application startup
struts config -- Servlet mapping (w.r.t struts).
and u can import servlets in jsp and can use it... there are so many possible ways of using servlets coz jsp pages inturn convert into servlets and got executed.....

    I have done up,but I found the program don't run as I have thought.
    Can you help me to find where is wrong?Very thank!

    You are trying to pass the current URL to the servlet
    from the applet, right?
    Well, what I put was correct. Your servlet code is
    trying to read some information from session data.
    request.getInputStream() is not the IP address of
    anything...see
    http://java.sun.com/products/servlet/2.2/javadoc/javax
    servlet/ServletRequest.html#getInputStream()
    Please read
    http://www.j-nine.com/pubs/applet2servlet/Applet2Servle
    .htmlNo,you all don't understand I.
    I want to send an Object to the server from a applet on a client.not url only.I maybe want to send a JPEG file instead.
    All I want is how to communicate with a servlet from an applet,send message to servlet from client's applet.
    for example,Now I have a method get the desktop picture of my client .and I want to send it to a server with a servlet to done it.How can I write the applet and servlet program?
    Now my program is down,But can only do string,can't not done Object yet.Can anyone help me?

  • Applet not communicating with servlet when given ip address (not localhost)

    I have a strange problem with my applet -
    I have a java applet and a Tomcat server running. I am able to communicate between the applet
    and a servlet on the server (sending strings from applet to servlet, for example..) when the
    URL that I write in the applet is -
    "http://localhost:8080/ProjectName/ServletName "
    BUT - when instead of that "localhost" I insert my ip address, it throws the exception:
    java.net.ConnectException: Connection refused: connect
    in the line -
    urlConn.getOutputStream(); (urlConn is the HttpURLConnection that I created with the URL)
    also, I did port forwarding (I have a router)
    so that 8080 port will be directed to my computer, and tested the forwarding, and it does work.
    Does anybody know why there is a problem?
    Thank you.. :)

    >
    well, in the final version of the project the applet will be signed.. >Uh-huh..
    >
    but, I got tired of signing it every time I edited the code, so now I just simply run it as a "java applet" project
    from the eclipse.. NOT as a signed jar..>Eclipse has Ant built in. Write a script that will compile/build/sign the jar for you, then build it to the point of being signed for every test run. (Just today I was making some changes to a signed applet project that does just that - I probably built it 25 times before I was happy with the changed code - not a problem.)
    >
    you think that's the problem ?>Yep. Not that I provide support for Eclipse, nor know how it goes about launching applets (trusted or sandboxed).

    I want to view this data in my application
    This application is not an applet. It is a class that extends JFrame
    Thanks you

    1:
    get it working passing text
    2:
    get it working passing a simple object
    3:
    then get it working using your example below
    Notes:
    You are try to mix text and objects
    PrintWriter out = response.getWriter();
    ObjectOutputStream os = new ObjectOutputStream(response.getOutputStream());This is not thread safe
    group = request.getParameter("g");You are rewriting to the same place

  • Communication with servlet using HTTPURLConnection

    Hi Again,
    well..trying to connect to a servlet using the HTTPURLConnection class.
    but the servlet is found (as i have put a system.out in init method of the servlet and that gets printed correctly).my problem is that the doget method does not get invoked.
    following is the code:

  • Communicating with servlet's?

    Hello,
    I am planning to a write a servlet which will include several methods for adding to a database, searching for records and amending records.
    The adding, search and amending will each involve separate html or jsp pages which will include the post method.
    I just wondered how best I could tell the servlet which html/jsp page is posting to the servlet?
    Is using something like addrecord.jsp?action=ADD
    Widely used, or are there better methods?
    Thank you

    Thanks
    Rather than using addrecord.jsp?action=ADD,
    do you think its better to input a hidden input in the html or jsp
    <input type="hidden" name="ACTION" value="ADD"/>

  • Applet failed to communicate with servlet for https, on tomcat5.0+apache2.0

    Hi
         I have a problem, we have a tomcat5.0 and apache 2.0 with jk connector, and an application where an applet comunicate to servlet.
    we need to set the ssl , the apache is configured with the ssl( openssl,).
    when I run the application with standalone tomcat with ssl
    connector (port 8443)enable, it runs fine for both http and https.
    i use httpsURLconnection for https communication from applet to servlet.
    But at production envoirment (Tomcat 5.0 , apache 2.0 and j connector with ssl enable at apache) it fails for https, all the jsps runs properly, but the applet isn't communicating with servlet. can anyone guess what is the problem.
    the exception dump is
    ava.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 401 SSL Connection Not Granted"

    Make sure your deployment is using a supported network configuration, we do not support running under localhost. Your SGD  server needs a valid DNS name configured.

  • VB Client communicating with a Java servlet

    Hi,
    I have a java servlet and I would like to have a VB application communicating with the servlet.
    Can I do it ? and if yes, how to do it.
    Thanks in anticipation,
    Ayana

    The VB client can open an internet or Http connection to the servelet, send a request and parse the response. We've done it here but I don't know exactly which ActiveX control the VB guy uses.
    Also look into using webservices.

  • Servlet Communication with Java WebStart

    Hi there,
    we have an application that works fine with Java WebStart whenever we start it in a local area network. But from outside the LAN the application cannot communicate to it's servlets. I use the codebase IP address with the servlet runner's port (http://<codebase IP>:port/) as URL for servlet communication, but the application's request never reaches the servlets.
    My question is now, if anyone had the same or a similar problem with servlet communication using Java WebStart, or if anyone knows, if that might be a problem with proxy configuration.
    The servlet runner we use, is JServ from Sun (JSDK2.0) and the webserver where it is running on is not behind a firewall or a proxy, but the client PC with the web start application is.
    Thanks,
    Katja

    Thank you for your early reply. But I think, that's not the problem.
    I get no security error and the webserver is identified the same way it is in the jnlp file. Also my application is not running in the Sandbox. My assumption is, that the http-request to the servlet does not go through the proxy server between my PC and the PC the servletrunner is running on.
    I wonder if I have to configure my application to use a proxy server for communication with the servlets instead of the direct http-request to the servlet runner?

  • Communication Applet - Servlet

    Hello,
    I'm trying to do a communication Applet - Servlet.
    When i'm typing in my browser internet explorer
    http://pcsm1:8080/servlet/MyServlet
    My servlet is invoqued perfectly and i see the good message in the prompt ms-dos (cf MS-DOS PROMPT : MESSAGE OF THE SERVLET!)
    But when i'm trying with my applet, i have a security exception : cannot access "pcsm1":8080
    SERVLET :
    public class MyServlet extends HttpServlet
    public void init(ServletConfig config)
    System.out.println("Servlet Init");
    public void doGet(HttpServletRequest request,HttpServletResponse response)
    ObjectOutputStream outputToApplet;
    long data=69;
    try
    outputToApplet = new ObjectOutputStream (response.getOutputStream());               System.out.println("Sending data to applet...");
    outputToApplet.writeLong(data);
    outputToApplet.flush();
    outputToApplet.close();
    System.out.println("Data transmission complete.");
    catch (IOException e)
    public void doPost(HttpServletRequest request,HttpServletResponse response)
    APPLET :
    public class MyApplet extends Applet
    public void init()
    try
    URL url = new URL("http://pcsm1:8080/servlet/MyServlet");
    or
    URL url = new URL(getCodeBase(),"http://pcsm1:8080/servlet/MyServlet");
    URLConnection servletConnection = url.openConnection();
    servletConnection.setDoInput(true);
    servletConnection.setDoOutput(true);
    servletConnection.setUseCaches (false);
    servletConnection.setDefaultUseCaches (false);
    servletConnection.setRequestProperty("Content-type","application/octet-stream");
    ObjectInputStream inputFromServlet = new ObjectInputStream(servletConnection.getInputStream());
    data = inputFromServlet.readLong();
    inputFromServlet.close();
    catch (Exception e)
    MS-DOS PROMPT : MESSAGE OF THE SERVLET
    when caller is internet explorer
    C:\Servlet\bin>servletrunner -d "c:\servlet\bin"
    servletrunner starting with settings:
    port = 8080
    backlog = 50
    max handlers = 100
    timeout = 5000
    servlet dir = c:\servlet\bin
    document dir = .\examples
    servlet propfile = c:\servlet\bin\servlet.properties
    Servlet Init
    Sending data to applet...
    Data transmission complete.
    What can i do to avoid my security exception problem?
    Very thanks...

    Are MyServlet and the HTML page hosting MyApplet being served from the same server (i.e., pcsm1:8080)? If not, this is a violation of one of the security constraints placed on unsigned applets.
    If the above scenario is the case, there are three options to overcome:
    1) Create a signed applet
    2) Move the HTML/Applet to the same server as the Servlet
    3) On the server serving the HTML/Applet, create a "proxy" servlet to which the applet can connect and which will in turn contact MyServlet (through HttpURLConnection)

  • Sir i am using datasocket read ,i am communicating with java but my problem is that bcz im using while loop to see if value has changed my labview consumes all the processors time ,sir i want a event like thing so that while loop is not in continuous loop

    sir i have given lot of effort but i am not able to solve my problem either with notifiers or with occurence fn,probably i do not know how to use these synchronisation tools.

    I want to pass along a couple of tips that will get you more and better response on this list.
    1) There is an un-written rule that says more "stars" is better than just one star. Giving a one star rating will probably eliminate that responder from individuals that are willing to anser your question.
    2) If someone gives you an answer that meets your needs, reply to that answer and say that it worked.
    3) If someone suggests that you look at an example, DO IT! LV comes with a wonderful set of examples that demonstate almost all of the core functionality of LV. Familiarity with all of the LV examples will get you through about 80% of the Certified LabVIEW Developer exam.
    4) If you have a question first search the examples for something tha
    t may help you. If you can not find an example that is exactly what you want, find one that is close and post a question along the lines of "I want to do something similar to example X, how can I modify it to do Y".
    5) Some of the greatest LabVIEW minds offer there services and advice for free on this exchange. If you treat them good, they can get you through almost every challenge that can be encountered in LV.
    6) If English is not your native language, post your question in the language you favor. There is probably someone around that can help. "We're big, we're bad, we're international!"
    Trying to help,
    Welcome to the forum!

    I'm trying to install windows 7 on my macbook pro. I went through the process of bootcamp telling it to install windows 7. Once the windows boot manager started an error message came up. The error message says " windows has encountered a problem communicating with a device connected to your computer. I don't have a usb connected to my computer. I  am using windows 7 professional install disc. I  can't figure out what i am doing wrong. The same message keeps coming up over and over. Am I doing something wrong or is it something else?

    Well, shucks, i just spent almost 30 minutes trying to find your model user guide to explain it better, I guess they never got around to making it.....
    I would just borrow another Windows disk and try installing it again and if it does it again then you might take it to an Apple Store and see if one of the "Genius' " can figure it out.
    Make sure your internet is enabled and click on your blank desktop and at the top of your screen is a Help menu option, enter PRAM and it should give you a list of things relating to Pram. It may take a few seconds to list anything as it has to connect to Apples severs first. It should list the things you may have to fill back in when your done.
    "P-ram" stores some common information that is used in the background, your date, time, startup disk, etc, that you don't have to re-fill when you restart, it's a little different for each computer.

  • "The software required for communicating with the iPod is not installed..."

    I realize my explanation of my problem is long-winded, so if you want a shortened version, here it is:
    I've followed all the instructions trying nearly everything, and no matter what I do, iTunes gives me the error saying: "The software required for communicating with the iPod is not installed correctly. Please reinstall iTunes to install the iPod's software." My G5 iPod (60GB) works on two other computers (both without any music on them), so I assume there something wrong with my computer and not the iPod itself.
    Now for the long-winded story of the last eight hours of my life...
    I just got the Generation-5 iPod Video (60GB) a today and I'm having problems already. I followed the instructions and installed the iPod software and then plugged in my iPod (iTunes has been on my computer for a while now). I was expecting iTunes to open after plugging in the iPod, but my device manager only detected and installed "a new device". I manually opened iTunes and got an error saying: "The software required for communicating with the iPod is not installed correctly. Please reinstall iTunes to install the iPod's software."
    After re-installing the iPod software and iTunes, and restarting my computer countless times, I came looking for help here. I found this page, which seemed to outline my problem exactly. My computer recognizes the iPod as a drive, but iTunes won't have anything to do with it. I have all the symptoms outlined in the heading, so I hoped to solve my problem there. I followed the instructions step-by-step, and after the final restart, I open iTunes to get the same exact error message.
    I decided to determine whether there was a problem with my iPod or if it was my computer. I plugged my iPod into my uncles's powerbook, and got to the point where I can name and configure my iPod. I expected it to work flawlessly on a Mac (which it did) but there is no way for me to continue using a Mac (after tomorrow) for my iPod. This formatted the iPod for a Mac, so I went to another (different from the original) Windows computer, clean of any iTunes and iPod software, and followed the instructions exactly as they're supposed to be followed. After the installations, I plugged in my iPod, and although iTunes didn't open, I was able to format back to Windows and name my iPod (a step in the right direction). I should note that my (anti-iPod) computer is a Windows XP Pro, and the working one is Windows XP Home Edition. This was all well and good, until I remembered there was no music on this computer. So my iPod is completely working there, but there isn't anything I can do with it.
    Next, I came back here and browsed around the discussion boards, hoping to find somebody with a similar problem to mine. There seems to be alot of errors concerning iTunes not recognizing the iPod, but none of the solutions I tried worked for me, including changing the drive letter. I get the "iPod Service Error" while trying to restore to factory settings through iPod updater.
    Of course, I could transfer all 32GB of music from one computer to another, but the second (working) computer isn't mine and I won't have access to it in a couple months. It would be most convenient if I could get my iPod working on my own computer. Any help would be appreciated, especially from somebody who has solved this problem or know how to solve this problem.
    P.S.
    Here are some other minor details that my be important, but I didn't feel they were worth including.
    - My brother has his iPod mini set up on my computer, under a different user login. He gets the same error once in a while, but re-installing iTunes always solves the problem for him. I had him try solving my problem his way, but nothing worked for him either.
    - My computer is an AMD Athlon 64 Processor 3200+, 512MB RAM with Windows XP Pro SP2 installed. My internal hard drive is partitioned, using the letters C, D and H (C being my system files, D used for recovery files and H for my applications and games). My E drive is used as a DVD/CD-ROM Drive, and drives F and G are reserved for virtual drives (none have been running during this entire ordeal). My external hard drive uses the letter I, and I manually set my iPod to use the letter J (I've never used 'J' for anything else before).
    - Yes, I have downloaded and installed the latest versions of iTunes and the iPod software.
    - I'm assuming there is a problem with my computer and not my iPod, since it worked on both other computers I tried. I'm hoping it's as simple as changing a registry file or cleaning out (yet another) temp directory.

    Solution to "Software required for communicating with the iPod is not installed"!
    I battled this same problem for about 5 hours. Going through re-installations, the "5 R's", all these discussion boards. Nothing worked.
    The problem is that iPodService was repeatedly crashing after minute or so. You can verify this by hitting Ctrl-Alt-Delete and noting that iPodService is missing from the process list (sort by image name), or by right-clicking on My Computer and selecting "Manage", then going to Services and checking out the IPodService service - if it gives you the option to "Start", then it's not running.
    Here is what worked.
    1. De-install iTunes and iPod (if you have the updater installed) completely by going to Start --> Control Panel --> Add/Remove Programs. Also delete the C:\Program Files\iTunes and c:\Progam Files\iPod\bin directories. (Don't worry, this doesn't affect your saved music files.)
    2. Log in as an Administrator
    3. Go into the registry (note this is dangerous - you should be careful) and remove the iPod entries that the uninstaller misses.
    3.1 Go to Start menu --> Run.
    3.2 Type in "regedit".
    3.3 Go to HKEYCLASSESROOT --> IPodService.iPodManager.
    There are two keys here, iPodManager and iPodManager.1. In my case, I did not have permission to view either of these. I think this is the root cause of the problem. I think the installer can't properly update these because it doesn't have permission. So you need to change the permissions:
    3.4 Right-click on IPodService.IPodManager
    3.4.1 Select "Permissions..." A warning will appear saying you don't have permission, but that you can change permissions.
    3.4.2 On the window that launches, click on "Advanced..."
    3.4.3 Click on the "Owner" tab.
    3.4.4 Select a valid account (the one you're logged in under) under "Change Owner To".
    3.4.5 Hit "OK".
    3.4.6 Back on the main Permissions window, hit Add and add the same account as a valid user.
    3.4.6.1 Where it says "Enter the object names to select", type in the account name, e.g. "Smith".
    3.4.7 Click on the "Allow" checkboxes for "Full Control" and "Read".
    3.4.8 Hit "OK".
    3.5 Repeat procedure for the "iPodManager.1" key.
    3.6 Now right-click and delete both of these keys.
    I think that's all that's required, but I also searched through the registry and deleted the following keys.
    4. Other keys I deleted:
    4.1 HKEYCLASSESROOT --> IPodManager.IPodManagerUI.1
    4.2 HKEYLOCALMACHINE --> SOFTWARE --> Apple Computer Inc. --> iPod
    I think that's all I deleted, but I'm not positive. I seached for instances of "ipod" using the Find... and Find Next functions under the Edit menu.
    5. Exit out of the registry editor.
    6. Re-install iTunes. I re-installed iTunes and reconnected the iPod, and everything worked.
    I want to repeat that editing the registry can completely mess up your computer if you modify the wrong things, so only do this if you're comfortable, and be extremely careful.
    Hopefully this helps!
    Apple support people: assuming this works, please add it to your solutions page, and feel free to reimburse me for spending half of Christmas figuring this out.
