Invoking the servlet on startup

How can i invoke the one servlet while server is getting started.
I am using the Apache Tomcat v 1.4
Actually i have to send some Message from one servlet A to servlet B.
Here while the server getting started i have to invoke the servlet A to send some message to servlet B.
Both servlets are in same same server.
Thanks in Advance

I presume you mean tomcat 4.1 ?
Add the following tag to your web.xml file under the servlet you want to start when the server starts:-
<load-on-startup/>
or if you need to assign priorities to several servlets that start when the server starts, use:-
<load-on-startup>1</load-on-startup>
where the lower the number, the higher the priority.

  • How to -only- invoke a Servlet/JSP

    Hi,
    I would like to invoke a Servlet or JSP inside a standalone application WITHOUT opening a stream. When I use url.openConnection() or con.connect() the servlet/JSP is not executed, I must also do "ObjectInputStream o = new ObjectInputStream(con.getInputStream());" in order to get the servlet/jsp executed.
    I just want to invoke the servlet/JSP, because I use the returned data for nothing.
    Thanks

    If you openConnection, you might also have to get the output stream from the servlet to make it work properly. (Otherwise, the server, or proxies in-between, might consider that the client has decided it doesn't want the page after all, and may stop requesting it.)
    A cheap way to request a page but get less data back would be..
    conn.setRequestMethod("HEAD");HEAD is exactly like GET, except it doesn't return the body (just the headers, hence the name.) Not entirely sure if it works on Java.
    Failing that, you should be able to just open the input stream, and close it again straight away.

  • How to invoke a servlet from an application-URGENT

    Hi,
              My requirement is as follows :
              I have to invoke a servlet from a client application. I am using
              java.net.URL and java.netURLConnection classes to
              open a connection and invoke the servlet.
              I am using WebLogic5.1
              my code snippet is as follows :
              URL url = new URL("http://localhost:7001/urlservlet");
              URLConnection connection = url.openConnection();
              connection.setRequestMethod("GET");
              connection.setDoOutput(true);
              connection.setDoInput(true);
              PrintStream outStream = new PrintStream( connection.getOutputStream() );
              outStream.print("message=hai");
              outStream.flush();
              outStream.close();
              When I execute the application, Webloigc server console is displaying the

              If you want to send Java object you have to use POST:
              URLConnection conn = ...
              conn.setDoOutput(true); // makes this a POST
              OutputStream os = conn.getOutputStream();

              os.close();
              InputStream in = conn.getInputStream(); // sends data to the server and
              // opens input stream
              ..read servlet response..
              .. ot just close the stream...

  • Invoking a servlet from an unix shell script

    I have successfully created a servlet that when loaded via a browser takes input values in a form. After hitting "submit" the results are returned to the browser.
    Now I would like to create an unix shell script that:
    1. takes input values from the command line
    2. invokes the servlet that does the necessary processing
    3. returns the results (via echo, or in a text file, etc.)
    Please give me any clues, hints, directions on
    1. how to convert my existing servlet to accommodate a shell script
    2. how to invoke the script within the shell script
    Please refer me to any existing examples if available.
    Thanks,
    George

    Using the code below as an example I think you are saying I should take the following steps in a java sample program:
    1. in a sample program create an Testservlet object -
    Testservlet newservlet = new Testservlet();
    2. to send input to the servlet execute -
    newservlet.doGet( ? , ? );
    I'm not sure what the parameters should look like
    but I guess one of them is the input value.
    3. to get output from the servlet execute -
    String results = null;
    results = newservlet.doPost( ? , ? );
    Again, I'm not sure what the parameters
    should look like.
    public class TESTservlet extends HttpServlet
    String connPool;
    public void init(ServletConfig config)
    throws ServletException
    super.init(config);
    connPool = getInitParameter("dataSource");
    if (connPool == null) {
    System.err.println("This servlet requires a " +
    " dataSource initArg." );
    public void doPost(HttpServletRequest req,
    HttpServletResponse res)
    throws ServletException, IOException
    // first, set the "content type" header of the response
    res.setContentType("text/html");
    //Get the response's PrintWriter to return text to the client.
    PrintWriter pw = res.getWriter();
    pw.println("test");
    String testinput = null;
    try
    testinput = req.getParameter("testinput");
    catch (Exception e)
    e.printStackTrace();
    pw.println("testinput = " + testinput");
    finally
    pw.close();
    public void doGet(HttpServletRequest req,
    HttpServletResponse res)
    throws ServletException, IOException
    res.setContentType("text/html");
    PrintWriter pw = res.getWriter();
    pw.println("Test Servlet");
    putForm(req, pw);
    pw.println("</body></html>");
    pw.close();
    * putForm() writes an HTML form to the response
    public void putForm(HttpServletRequest req,
    PrintWriter pw)
    throws IOException
    pw.println("<form action=\"" +
    req.getRequestURI() +

  • Tomcat 4 as service plus invoke servlet on startup

    Hi all. My two questions are as follows, any feedback is much appreciated.
    1st)
    I wish to run tomcat as a service where it will start automatically on startup plus you can restart it from the win 2000 service console. I have followed the advice on the following link http://www.prabhums.org/weblogs/?postid=237 which places an entry into the service console but doesn't start or stop tomcat as required.
    2nd)
    On tomcat startup I wish to invoke a servlet when the service starts. Where would I config this and any parameters etc? web.xml?
    Thanks in advance
    Tas

    It's very simple to have a servlet startup. Just use the load-on-startup element in your wbe.xml when you define the servlet.
    <servlet>
       <servlet-name>MyServlet</servlet-name>
       <servlet-class>com.kcole.mypackage.MyServlet</servlet-class>
       <load-on-startup>1</load-on-startup>
    </servlet>Use a different number. I believe the numbers indicate order of startup.
    We use them to mainly to start processes/threads that run at an interval, like a TimerTask for example. We use them for things like setting up our custom connection pool and setting up jobs such as checking directories for files to import, etc.
    As to what the request and response objects contain, I don't think there are any. The servlet spec doesn't say regarding this when using the load-on-startup. It runs the init() method.

  • Invoking the creation of an array with servlets

    I have a servlet that first creates an array of catalogue items that allows site users to add products to a shopping cart, obtaining information for each product from the catalog items array. Because I am forced in this scenario to declare the array first and create it later on in the code and cannot declare and create it at the same time, I have to allocate a size for it. e.g.
    private static CatalogItem items[] = new CatalogItem[60];
    However this is not very good as if a second site user invokes this array then there will be an out of bounds exception. Can anyone give me advice on how I can declare an array of certain size but not have it give out of bounds exceptions everytime it is invoked??
    by the way this is what I am trying to do, but it only allows the servlet to be invoked by one site user at the moment...
    private static CatalogItem items[] = new CatalogItem[60];
    while(rs1.next()){
                   // getInt or getString or getFloat etc to get the appropriate
              recordingidDB = rs1.getInt("recording_id");
              imageDB = rs1.getString("image_name");
              titleDB = rs1.getString("title");
              directorDB = rs1.getString("director");
              categoryDB = rs1.getString("category");
              durationDB = rs1.getInt("duration");
              ratingDB = rs1.getString("rating");
              yearDB = rs1.getString("year_released");
              priceDB = rs1.getFloat("price");
              items[i] =
                new CatalogItem
                  (recordingidDB,
                    titleDB,
                    directorDB,
                    categoryDB,
                    durationDB,
                    ratingDB,
                      yearDB,
                    priceDB);
              i++;          
         } //while rs1 endanyone??

    I'd look into an ArrayList or other Collection of some sorts so you can dynamicly expand / decrease the size.

  • Method to get the file path that invoked a servlet

    i have a html file that invokes a servlet.Within the servlet i want a method that gives me the path of the html file.Is this possible without using cookies.or is there any method that serves my purpose?

    Hi,
    after reading the last posts I think you should try what KPSeal said (althought I haven't tried it) or use my last suggestion :
    on your HTML link (which will be handled by server) add an extra parameter (e.g. http://handle.xxx?page=mypage.HTML) and catch it inside the servlet code to know from what page it came.
    nevertheless, about the getRequestURL() (and getRequestURI()) it's a method from the interface HttpServletRequest, in the package javax.servlet.http that comes in the Servlet API. (you can find the servlet API at http://java.sun.com/products/servlet/download.html), but I believe if you have a servlet you already should have inside it the request object.

  • How to invoke a servlet from the command line

    Hi,
    I have a process that needs to do something remotely. One of the ideas is to have a servlet on the other side that can do that. So the question is how can I invoke it from my process?
    Thanks,

    First approximation to code:URL remoteTask = new URL("http://yourserver.org/yourservlet");
    InputStream response = remoteTask.openStream();
    // read the servlet's response from that InputStreamYou will find more comprehensive versions of this code if you search the forum.

  • ADF Bindings Servlet/Filter  not invoking  Faces Servlet

    I'm getting ADF Faces and Facelets working properly with pages written in jspx format, but the Faces Servlet being mapped to jsf format.
    The problem I'm getting is while displaying ADF Tables with data retrieved from the database using Toplink and bindings provided by ADF Databindings.
    The following is the Web.xml mappings for Faces Servlet and ADF bindings filter:
    <servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
    <servlet-name>resources</servlet-name>
    <url-pattern>/adf/*</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.jsf</url-pattern>
    </servlet-mapping>
    <filter>
    <filter-name>adfBindings</filter-name>
    <filter-class>oracle.adf.model.servlet.ADFBindingFilter</filter-class>
    </filter>
    <filter-mapping>
    <filter-name>adfBindings</filter-name>
    <url-pattern>*.jsp</url-pattern>
    </filter-mapping>
    <filter-mapping>
    <filter-name>adfBindings</filter-name>
    <url-pattern>*.jspx</url-pattern>
    </filter-mapping>
    I'm getting the ADF tables displayed using ADF Bindings, if the faces servlet is mapped for jspx format;but, at the cost of losing Facelets...Facelets is not working with Faces Servlet mapped to jspx format(though written in jspx format, the faces servlet mappping has to be made for jsf format.On the other hand, if I use faces servlet mapping for jsf pages I'm getting Facelets working but ADF Databindings are not working ,(I guess) and hence ADF Faces Tables are not being displayed(I'm getting Access Denied message).
    I even tried to change the ADF binding filter mappings
    ---- from ---- jsp &jspx---- to ----- jsp and jsf ----
    But I got the same Access denied message.
    I read a similar post on this forum by Mr.Ashish Kumar who said he is using java script and automatic form submission, to refresh the page and that gave him the table working.
    as quoted in the post:
    af:table displays Access Denied
    Why should the page be refreshed at all. I Guess , the Faces Servlet is not being invoked by the ADF Bindings Filter/Servlet, and for this , I suppose , Mr.Ashish is using java script to provide the action required.
    And one more thing which that Automatic Refreshing of page using JavaScript cannot do.
    Suppose,
    I need customised display, rather than just a Table or Form,like:
    public String getEmp() {
    BindingContainer bindings = getBindings();
    OperationBinding operationBinding =
    bindings.getOperationBinding("findAllEmp");
    Object result = operationBinding.execute();
    if (!operationBinding.getErrors().isEmpty()) {
    return null;
    List<Emp> res=(List<Emp>)result;
    for(int i=0;i<res.size();i++)
    Emp myrec=res.get(i);
    System.out.println("Employee ["+myrec.getEname()+"], Salary ["+myrec.getSal()+"]");
    return "";
    where I do some customisation in the backing bean.
    and I call that method binded to a button as below:
    <af:commandButton
    text="findAllEmp"
    disabled="#{!bindings.findAllEmp.enabled}"
    binding="#{backing_Success.commandButton1}"
    id="commandButton1"
    action="#{backing_Success.getEmp}"/>
    What I'm getting is a disabled button.
    Why doesn't ADF bindings servlet invoke the faces Servlet?
    Can't we make ADF Bindings Servlet invoke Faces Servlet by configuring in the web.xml?
    Can't we get ADF Bindings filter mapped to work with jsf pages?
    Won't ADF Bindings work with jsf pages, will they work only with jspx pages?
    ADF Team,
    Please Help me.
    Thanking you,
    Samba

    Hi! Frank,
    Thankyou for your Reply.
    Yes, Mr.Adam Winer has contributed that library, I guess.
    But I already have that adf-facelets.jar in my lib folder ; and with out that the Facelets won't work with ADF faces , in the first place.
    I'm getting Facelets working excellently with ADF Faces but I'm not getting ADF Bindings working with Faceletpages.
    The thing is even in another application which does not have facelets in it, if we use mapping for jsf pages, ADF Bindings are not working.
    I think the ADF bindings filter is configured some where to work with jspx pages only.Could you tell me where to change that entry to make ADF Bindings work with jsf extension?
    Thanking you,
    Samba.
