Lazy loading of records into a Jsp page

Hi,
I am having 1000 records in a result set. There is variable called Pn whose value is 100. For the first request to the jsp , it should fetch and display only the Pn number of records. As I cannot see all the 100 records on the browser at a time, I am providing a scroll bar to see all the 100 records. When scroll bar reaches at the 100th record and tries to see the next record by clicking on scroll bar it should fetch another Pn(100) number of records and display. Like that at the end of every Pn th record it should fetch another Pn number of records until all the 1000 records are displayed. Constraint is I should not use Next or Previous buttons.
Please let me know how to achieve this functionality and what is the scroll bar event I suppose to write to fetch next Pn number of records.
Thanks
Subbarao.

  • Importing visual jsf page into another jsp page

    Hi
    I am developing a web application using jsp and struts. I want to embed a visual jsf page that Ive created into another jsp page (which is a normal jsp page, not a jsf one.)
    Ive tried quite a few things but nothing seems to work..
    <jsp:include page="Page2.jsp">
    Ive surrounded the code in the f:subview tags. still doesnt work.
    Ive tried using <jsp:useBean id="Page2" scope="page" class="visualwebapplication.Page2" > .. It does not give me an error, but does not embed the page as well. Do I need to some other code after this to use the above bean to display the page.
    Any help would be greatly appreciated.
    Regards

  • Including JavaScript into a JSP Page

    Hi,
    How do i include a piece of JavaScript <SCRIPT> stuff into a JSP Page?
    Right now i have an HTML Page that includes some <SCRIPT> code. Now many other HTML files use this piece of <SCRIPT> stuff. How do i remove it , put it in one place(I mean where to put it and what would that file be called) and in a JSP page call this <SCRIPT> code?
    Please help . i'm pretty new to JSP and JavaScript.
    Thanks in Advance.
    Phani
    /**** CODE
    <SCRIPT language=javascript>
    <!--
         if ((document.images) && ("Netscape" != navigator.appName) && (navigator.appVersion.indexOf('Mac') == -1))
         document.write("<LINK REL=\"stylesheet\" TYPE=\"text/css\" HREF=\"http://www.telia.se/tews/css/1.css\">");
         else if ((document.images) && ("Netscape" != navigator.appName) && (navigator.appVersion.indexOf('Mac') > 1))
         document.write("<LINK REL=\"stylesheet\" TYPE=\"text/css\" HREF=\"http://www.telia.se/tews/css/5.css\">");
         else if (("Netscape" == navigator.appName) && (parseInt(navigator.appVersion) == 4) && (navigator.appVersion.indexOf('Mac') == -1))
         document.write("<LINK REL=\"stylesheet\" TYPE=\"text/css\" HREF=\"http://www.telia.se/tews/css/2.css\">");
         else if (("Netscape" == navigator.appName) && (parseInt(navigator.appVersion) == 4) && (navigator.appVersion.indexOf('Mac') > 1))
         document.write("<LINK REL=\"stylesheet\" TYPE=\"text/css\" HREF=\"http://www.telia.se/tews/css/3.css\">");
         else if (("Netscape" != navigator.appName) && ("Microsoft Internet Explorer" != navigator.appName))
         document.write("<LINK REL=\"stylesheet\" TYPE=\"text/css\" HREF=\"http://www.telia.se/tews/css/6.css\">");
    // -->
    </SCRIPT>

    Ok, first let us make clear the demarcation between java and javascript.
    Java runs on the server, and produces an HTML page which is sent to the client.
    That HTML page may contain javascript code on it to run on the client side.
    As the page is loaded, javascript may be compiled/run on the client.
    So you have some javascript code which you want to include on every page as template text?
    I would do this in JSP by using the include directive to add that bit of template text to every single JSP page.
    ie
    header.jspf
    <SCRIPT language=javascript>
    <!--
    if ((document.images) && ("Netscape" != navigator.appName) && (navigator.appVersion.indexOf('Mac') == -1))
    document.write("<LINK REL=\"stylesheet\" TYPE=\"text/css\" HREF=\"http://www.telia.se/tews/css/1.css\">");
    else if ((document.images) && ("Netscape" != navigator.appName) && (navigator.appVersion.indexOf('Mac') > 1))
    document.write("<LINK REL=\"stylesheet\" TYPE=\"text/css\" HREF=\"http://www.telia.se/tews/css/5.css\">");
    else if (("Netscape" == navigator.appName) && (parseInt(navigator.appVersion) == 4) && (navigator.appVersion.indexOf('Mac') == -1))
    document.write("<LINK REL=\"stylesheet\" TYPE=\"text/css\" HREF=\"http://www.telia.se/tews/css/2.css\">");
    else if (("Netscape" == navigator.appName) && (parseInt(navigator.appVersion) == 4) && (navigator.appVersion.indexOf('Mac') > 1))
    document.write("<LINK REL=\"stylesheet\" TYPE=\"text/css\" HREF=\"http://www.telia.se/tews/css/3.css\">");
    else if (("Netscape" != navigator.appName) && ("Microsoft Internet Explorer" != navigator.appName))
    document.write("<LINK REL=\"stylesheet\" TYPE=\"text/css\" HREF=\"http://www.telia.se/tews/css/6.css\">");
    // -->
    </SCRIPT>
    <noscript>
      // stuff here for when the browser does not support javascript
    </noscript>And then in every jsp page
    <%@ page include="header.jspf" %>
    // rest of the JSP pageThe file "header.jspf" will be included with every jsp page served, and you only need to update that page in one place.
    If you have a JSP2.0 container you can define a jsp prelude which will be the same as having the <%@ page include="header.jspf" %> on every page.
    You do this in the web.xml file:
    Something like this:
      <jsp-property-group>
         <url-pattern>*.jsp</url-pattern>
         <include-prelude>/WEB-INF/jspf/prelude1.jspf</include-prelude>
      </jsp-property-group>The specified file will be loaded into every JSP page without the JSP page having to define the import itself.
    Hope this helps,

  • What's up when you drag and drop a table into a jsp page?

    Hi All,
    I was wondering what's happen in dragging and drop a table into a jsp page. This question because untill yesterday i had an application up and running, with a table displaying a number of rows of the database, and an action associated with an update into a database.
    The action is managed trough JNDI, defined from Preference-Embedded.......
    It was working.
    Then the machine hosting the db changed IP addres. I went into Webcenter Administration console, I've changed the connection string into the jdbc parameters, by updating the new IP address... but it's not working anymore! The log comes out with a big error, but basically it can't connect at the db!
    So, I think there is somewhere some reference to the old db.....where???
    Thanks
    Claudio

    Yes Shay,
    I got this error:
    JBO-29000: Unexpected exception caught: oracle.jbo.JboException, msg=JBO-29000: Unexpected exception caught: oracle.jbo.JboException, msg=JBO-29000: Unexpected exception caught: oracle.jbo.DMLException, msg=JBO-26061: Error while opening JDBC connection.
    in few hours I'll be able to give you the full stack.

    Hi Shay,
    Thanks a lot..you were right.
    I've located the ba4j on the webcenter server...and I've noticed that it was with the old address.
    I think it's a bug, cause on the local machine (before to deploy) this file comes with the right address.
    So next time, before to redeploy a new application, I think I'm going to fiscally delete the folder from j2ee folder.
    Thanks again for the help!

  • How do I Display a string from a servlet into a JSP Page???? NEED HELP!!!!

    Hi guys,
    How do I Display a string from a servlet into a JSP Page...
    Ive tried so many bloody things!.....
    Simply.
    I get text from JSP. The servlet does what ever it does to the string.
    Now. Ive create sessions and bean things,.... how the hell do I display it in a text box... I can display on the screen.. but not in the text box.!!!
    please help!!!

    hmmm, I dont really like using JSP programming, u should be using JAVA..
    the way to do it is:
    Call and cast to the bean like this:
    <%@ page import="beans.*" %>
    <% //cast to bean get request create object
    userNameBean u= (userNameBean) request.getSession().getAttribute("userNameBean");
    then... all you do is call it like this:
    <input type="text" name="firstName" value="<%= u != null? u.getFirstName(): "" %>">
    this is the real programmers way,,,

  • How include a Servlet into a JSP page?

    Hi!!
    I need make a combobox with a servlet and place its result into a jsp page.
    The servlet is in a package, but when i do: <jsp:include file="sic.view.servlet.ComboServlet" />
    tell me that "file attribute isn�t a valid attribute name"
    whow can i do to make the combobox whit the servlet and include this into the jsp page??
    Thanks!!
    PD: Sorry my pour English...

    Servlets should be mapped to a URL, then you access the servlet via that URL.
    The servlet mapping is done in the web.xml (in WEB-INF/ directory of your web application)
      <servlet>
        <servlet-name>
          Combo_S
        </servlet-name>
        <servlet-class>
          sic.view.servlet.ComboServlet
        </servlet-class>
      </servlet>
      <servlet-mapping>
        <servlet-name>
          Combo_S
        </servlet-name>
        <url-pattern>
          /combo
        </url-pattern>
      </servlet-mapping>Then you would use:
    <jsp:include file="combo" />
    to include it.
    Make sure the class file gets put in the right package under WEB-INF/classes/

  • How do i display every 10 Records in my JSP page??

    Hi..
    I have developed one web-page which shows ALL employee records fetched from a employee table and display them in my JSP page.
    It has contain more than 1000's of records. I need to display first 10 Records in my page. There should be some 4 links below the records display which get me to see next 10 records or previous 10 records or first 10 records or Last 10 records.
    IS it possible in JSP??
    This is my sample code for your ref:
    <jsp:useBean id="empOperation" class="com.venki.gen.EmployeeOperation" />
    <html>
    <head>
         <title>Stardeveloper : DataAccess JSP Tag</title>
         <style>
         p, td { font-family:Tahoma,Sans-Serif; font-size:8pt;
              padding-left:15; }
         </style>
    </head>
    <body>
    <p align="center"><u>DataAccess JSP Tag</u></p>
    <%
         EmployeeList empList[] = null;
         empList = empOperation.getEmployees(empName);
    %>
    <table align="center" border="0" width="90%" cellspacing="2" cellpadding="2">
    <tr bgcolor="#CCDDEE">
         <td>EMPNO</td>
         <td>EMP Name</td>
         <td>DESIGNATION</td>
    </tr>
    <%if(empList!=null)
         for(int i=0; i<empList.length; i++)
          EmployeeList emp = empList;%>
         <tr bgcolor="#F7F7F7">
         <td><%= emp.getEmpNo() %></td>
         <td><%= emp.getEmpName() %></td>
         <td><%= emp.getEmpDesignation()%></td>
         </tr>
         <% }%>
    </table>
    </body>
    </html>
    It would be extremely useful,if i know the technique how to display every 10 Records thru JSP.
    Waiting for You people valuable reply and code!
    Regards
    venki

    I do it by pages. i.e. http://example.com/page.jsp?page=1 would show records 1-10, ?page=2 would show records 11-20
    let's pretend each record is identified by one field in the database, `id`
    then the SQL query you'd use to grab the records could be..
    SELECT * FROM `your_table` WHERE `id` >= (page*10) and <= (page*10+10)or this might even work:
    SELECT * FROM `your_table` ORDER BY `id` ASC LIMIT (page*10),10(all examples untested as I'm at work :P)

      </tr>  
    </table>  
    </form>Login is sucessful and I am brought to the 'studentstub.jsp' page. I would like the user name to appear on the 'studentstub.jsp' page. I used the following code in the 'studentstub.jsp' page :
    <td><%= request.getParameter("j_username")%></td>  but all I am getting is a null. The 'j_security_check' servlet is not exactly part of my package, but the glassfish app server. Is there anything wrong in the way I am extracting the information from 'j_security_check' ? Hope someone can advise, thanks.

    Hi Folks..
    I managed to get a reply from another forum and the suggested solution works. I am going to share it with everyone here.
    I repalced this line of code:
    <td><%= request.getParameter("j_username")%></td>with this:
    <td><%= request.getRemoteUser()%></td>The 'getRemoteUser' method from HttpServletRequest returns the name of the authenticated user. I hope this information will be helpful to those caught in a simillar problem. Thanks.

  • Retrieving lists from other layer into a JSP page - Design Question

    Hi all,
    What should be a good design technique in order to allow a JSP page to present some list obtained from other layer of my application. I intend to leave only presentation logic in the JSP layer, while all data access will be in other layer.
    For example, I have a JSP page that will show the results of a SQL query originated from an entry form in other JSP page. Let's name them 'search.jsp' and 'result.jsp'
    I want that all JDBC access be done in some other layer.
    Question 1:
    What would be better for this task? A servlet or a bean? (A bean, I suppose?)
    Then this bean (?) would have to find some way to pass all the result set into this 'result.jsp'. I think it would be very poor design if I used some Data Object, because it would have to store all rows and pass them at once.
    I don't want, either, that the presentation (JSP) layer access directly the data access layer (JDBC, files...). This way, I don't want any JSP page accessing the Resultset object directly.
    Question 2:
    What do you think could be a good design technique?
    I thought of some intermediate layer that provided data objects and data access interfaces. I mean, as my data will come from different sources, like some database (JDBC), some Electronic Document Manager, I thought of having a common access interface, that would provide methods for accessing the resultsets. This could be even a java.util.Enumeration that has a hasMoreElements() method that could be implemented as the next() method from JDBC result sets and the nextElement() method that would actually bring the next row of data.
    This way the JSP layer would see only hasMoreElements() and nextElement() methods from the middle layer. On the other hand, the data layer would provide as many different implementations to this access interface (Enumeration?) as there were data sources (JDBC, Files, ...)
    Question 3:
    What do you think of this design?
    Question 4:
    Is there any flaw in my approach? Which?
    Question 5:
    Could you suggest other designs?
    I really thank you all, for any kind of answer. I actually use this design for development, however I've never seriously discussed it with someone... this is going to be of great value for me.

    Well I saw you question and I'll tell you what I do.
    I have JSP's which post form data to servlets.
    The servlet then calls a factory to produce a ResultContainer (analagous to your lists) which is generated
    via JDBC, and/or request parameters etc...
    this provides a single point of reference and a "group" of containers (functions really) that can be produced and reused (same container different amount of data)
    I also have other static classes which can manipulate the data in the containers
    (such as add additional info to the items in the containers) before I forward the container (request attribute)
    to the JSP page
    Additionally I use Type safe constants for all my HTML form tag names (easier to change and ensure the same name is used everywhere when reading parameters) and again for item statuses
    and any other info I need to send along with the page (using Javascript to update the
    status to another type safe constant).
    I've found that using factories for ResultContainers is very worthwhile and allows you to implement additional servlets extremely quickly (mostly reusing containers that exist) and since the
    container is the same for all my JSPs (this may not be the case with you) I can implement JSP's
    very quickly as well (just change the view)
    btw I refrain from calling my ResultContainer a bean because it is not serializable
    I don't know if this will help but at least it gives me a forum to test my ideas
    Thanks

  • Include a Servlet into a JSP page

    Hi guys,
    When i try to include a Servlet into my JSP, the execution of the JSP stops...Somebody know why???

    Hi guys,
    When i try to include a Servlet into my JSP,the
    execution of the JSP stops...Somebody knowwhy???
    No, and do you know why ? Bcos including a
    servlet
    in
    a jsp doesnt stop the execution of the jsp. Sotell
    us that you tried to do, post some relevant
    code,
    for us to help you.
    ram.<%@page contentType="text/html"%>
    <%@page pageEncoding="UTF-8"%>
    <%@page buffer="500kb"%>
    <html>
    <head><title>JSP Page</title></head>
    <body>
    <jsp:include page="/showCryptValue"
    ptValue" flush="true" />
    asdfasdfasdfasdfasdf
    </body>
    </html>
    that's the source code....do you have any idea????
    Thak's a lottttFrom linxpda:
    1) setting the flush="false" parameter for thejsp:include tag?
    Here is the problem that I, and perhaps linxpda,
    think you have:
    You get an exception in the servlet.
    You have already written to and flushed the response,
    therefore you can not see the exception on your
    screen (seeing the exception on screen requires a
    send redirect to the error page, which can't happend
    when the response is already committed).
    The exception that is occuring MAY be alreay written
    in your logs, take a look.
    To see the problem on screen so as to be able to
    identify it, make sure your include tag DOES NOT
    flush the buffer. That means change
    <jsp:include page="/showCryptValue" flush="true" />
    to
    <jsp:include page="/showCryptValue" flush="false" />Hi!
    No even setting flush false or true it works...If somebody have done this before tell me how have you did....If you can post your code!

  • Loading Java Class File in JSP page

    I'm trying to load a java class file from a jsp page.
    (e.g. MyFile.java <-- Source "MyFile.class<--Class file of MyFile.java")
    jsp page
    <%@ include file = "MyFile.class" %>
    <HTML> // HTML Tags are here
    MyFile.java
    A normal java source file that has "public static void main" in it.
    My jsp page can display it's contents, 'except' for showing e.g. "1235%%215648%%public%%$$@##" through out the page...
    My guess is that it can't display my java class file..
    Can anyone please help me solve this problem of mine ?
