Calling servlet from another method

Hi,
I am writing a program which requires executing another servlet from within
thie main program. I do not care to return the information from the servlet
request.
http://usx500.crn.st.com:7000/TPMCenter_V2/insertAutomationValue.do?reqCode=confirmed
Thanks for the help.

The reason I continue posting this question, is because I cannot find a solution.
I have looked through the link provided, as well as many other solutions on the web,
none which have been successful. Following are two solutions which I have tried, and
niether have worked. I still am in need of some help in resolving this. If you would like
to assist me in this it would be greatly appreciated.

Solution 1 ---
    try {
        // Construct data
        String data = URLEncoder.encode( "reqCode", "UTF-8") + "=" + URLEncoder.encode( "show", "UTF-8" ) ;
        // Create a socket to the host
        String hostname = "usx500.crn.st.com" ;
        int port = 7000 ;
        InetAddress addr = InetAddress.getByName( hostname );
        Socket socket = new Socket( addr, port );
        // Send header
        String path = "/TPMCenter_V2/insertAutomationValue.do";
        BufferedWriter wr = new BufferedWriter( new OutputStreamWriter( socket.getOutputStream(), "UTF8" ) ) ;
        wr.write( "POST " + path + " HTTP/1.0\r\n" );

        wr.write("\r\n");
        // Send data
        wr.write(data);
        wr.flush();
        wr.close();
    } catch (Exception e) {
        e.printStackTrace() ;

  • How to call a servlet from another servlet

    hi everybody,
    i have a problem, i have to call one servlet from another one.
    Everything works on my pc, but when i install the application on the customer's server i got an error about an Uknown URL followed by the name of the machine.
    Wjat i do is the folloqing :
    String urlString = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+"/"+servletName;
    URL url = new URL(urlString);
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    the variable servletName is the name of the servlet i have to call.
    Is there another way to call the servlet ?
    All the servlet are installed in the same server.
    Any suggestion ?
    Cheers.
    Stefano

    Sweep is correct about requestDispatcher being another approach for inter-servlet delegation; the only issue that i recall with this approach is that it defaults the method of the destination servlet to the one it was called from...for example, calling servlet2 from within servlet1.post() resulted in the dispatcher attempting to utilize servlet2.post() - i believe that i searched for a parameterize solution to no avail :( (ended up handling the request by placing a "fake" doPost() in servlet2 that simply called servlet2.doGet())
    however, if your application is functioning correctly on your pc/webserver then the problem may be external to servlet communication (e.g. client webserver's ports not configured or blocked, missing runtime classes, etc.)
    my suggestion would be to set aside the programmatic concerns for the moment - what is the response if you open a browser on a client's machine and access the URL in question (i.e. http://clientserver:port/stefanoServlet)? If it will not respond to access in this manner then it certainly won't when your application calls for it.
    It's possible that there is a coding error but, given the info supplied, i'd start examining the environment, first. Let us know if you have any luck with the test i recommended or not (please provide abundant detail). Or, if you've found the solution then you may want to post back with a quick blub so the next person knows how to escape the trap.

  • Calling a servlet from another servlet?

    Hi
    I would like to know that how can I call one Servlet from another Servlet. I have tried getServlet() method of ServletContext but it has been deprecated. I want to call a specific method of the other Servlet, is there any other way?
    Thanks

    I should have seen it from your previous post :(
    Code of Servlet 1:
    public void doGet(HttpServletRequest request,
    HttpServletResponse response) throws
    ServletException, IOException
    RequestDispatcher rDispatch = null ;
    rDispatch = getServletConfig
    ().getServletContext().getRequestDispatcher
    ("/Servlet2") ;
    rDispatch.forward(request, response) ;
    System.out.println("Back in 1");
    I assume Servlets 1and 2 are in same web app and you've mapped your servlet2 to /Servlet2 in your web.xml
    make it as
    rDispatch = request.getRequestDispatcher("/Servlet2");
    rDispatch.forward(request,response);
    Nothin's wrong with yer servlet2

  • Calling servlet from a java program

    Hi
    I need to call a servlet's doPost() method from a java program. I have a specific situation, where I need to call servlet from a java program. DUring this call I need to pass a file and two string to the servlet. Servelt after receiving the file and string uploads the file to the server at a specified location. I am stuck up as how to call servlet from a java program instead of a HTML or JSP.
    Can anyone help me to start with this.
    any suggestion is welcome.

    You have to establish a URLConnection with servlet from your java program.
    URL servletURL = new URL("http://localhost:8080/Myservlet?str1=abc&str2=def");
    URLConnection servletConnection = servletURL.openConnection();you can get the objectOutputStream
    ObjectOutputStream oos = new ObjectOutputStream (servletConnection.getOutputStream());
    oos.writeObject(your file object);-------------------------------------------------
    In the servlet u can get the strings using request.getParameter("str1");
    In the servlet u can get the strings using request.getParameter("str2");
    file = new ObjectInputStream (request.getInputStream()).readObject()a lot of resources are available on this ...
    hope this helps :)

  • Calling Servlet from a java prog?

    Hi all,
    I am calling servlet from a java prog (Java Agent in Lotus Notes) by using URL and URLConnection object. how can i trigger the Servlet By using doPost method .I have to send some parameter also.
    Thanx
    Muthu

    you need to open a connection to the servlet. Then you must call getInputStream() and getOutputStream() and use them in any way you see fit. I was trying this before and could not get POST to work unless I openned the input stream from the servlet. Strange... but doGet worked without openning the input stream???
    // open a connection....
    // write to the servlet
    servletConnection.getOutputStream().write("whatever");
    servletConnection.getOutputStream().flush();
    servletConnection.getOutputStream().close();
    // grab what the servlet sends back, required to do a post.
    byte [] in = new byte[100];
    servletConnection.getInputStream().read(in);
    servletConnection.getInputStream().close();

  • How do I access array elements in one method from another method?

    Hi all!
    How do I access the array's elements from another method so that method 2 can have access to method 1's array elements? Thanks for any help!
    I am trying to create a simply program that will use a method to create an array and a SEPARATE method that will sort the array's elements (without using java's built in array features). I can create the program by simply having one method and sorting the array within that same method, BUT I want to sort the array from another method.
    Here's my code so far:
    public class ArraySort {
       public static void createArray(int size){
           double myArray[] = new double[size];    //create my new array
           for(int j=0; j < myArray.length; j++)
              myArray[j] = (200.0 * Math.random() + 1.0);   //fill the array with random numbers
       public static void sortArray(){
           // I WANT THIS METHOD TO ACCESS THE ARRAY ELEMENTS IN THE METHOD ABOVE, BUT DON'T KNOW
          //  HOW???? Please help!
        public static void main(String[] args) {
            createArray(4);    //call to create the array
    }Thanks again!
    - Johnny

    Thanks for the help all! I ve managed to get the program working, using java's built in array sort, but when i try to call on the array sort method from WITHIN my main method, nothing happens!
    Can somebody please tell me why I am not able to call on the sort method from within my main class???? Thanks!
    public class ArraySort {
       public void createArray(double[] arrayName, int size){
           double myArray[] = new double[size];  //create new array
           for(int j=0; j < myArray.length; j++)
              myArray[j] = (200.0 * Math.random() + 1.0);    //populate array with
           }                                                 //random Numbers
           sortArray(myArray); 
       } //Sort array(if I delete this & try to use it in Main method --> doesn't work???
       public void sortArray(double[] arrayName){

  • Different ways to invoke a servlet from another servlets?

    Hello,
    I am a bit confused today. I was thinking about all the ways by which I can invoke a servlet from another servlets. I know it can be done by creating an instance of the 2nd servlet in the 1st one. Is there any other way? such as say.... RequestDispatcher perhaps?
    Here is an example to illustrate my point. I have a login.jsp which submits to login.do. login.do search through database and first authenticate email and then the corresponding password. Now its time for displayGame.do. So here how do i do? if it was a displayGame.jsp then i could have used Redirection or Forward but when it is servlets? Can I still go for Redirection or Forward??
    Thank you for reading this confused post. :-)

    if it was a displayGame.jsp then i could have used Redirection or Forward but when it is servlets?Question: do you know what a JSP becomes when you first run it?
    Answer: a servlet.
    So yes, you can use a RequestDispatcher to forward/redirect to a servlet OR a JSP, whatever you like.

  • How to call a specific method in a servlet from another servlet

    Hi peeps, this post is kinda linked to my other thread but more direct !!
    I need to call a method from another servlet and retrieve info/objects from that method and manipulate them in the originating servlet .... how can I do it ?
    Assume the originating servlet is called Control and the servlet/method I want to access is DAO/login.
    I can create an object of the DAO class, say newDAO, and access the login method by newDAO.login(username, password). Then how do I get the returned info from the DAO ??
    Can I use the RequestDispatcher to INCLUDE the call to the DAO class method "login" ???
    Cheers
    Kevin

    Thanks for the reply.
    So if I have a method in my DAO class called login() and I want to call it from my control servlet, what would the syntax be ?
    getrequestdispatcher.include(newDAO.login())
    where newDAO is an instance of the class DAO, would that be correct ?? I'd simply pass the request object as a parameter in the login method and to retrieve the results of login() the requestdispatcher.include method will return whatever I set as an attribute to the request object, do I have that right ?!!!!
