  • How can I stop the execution on a JSP page and start it again

    Hi
    I am making a program that simulates how to manage transactions when accessing a database by using locks. I have run into a problem and I hope someone has the time to help me.
    When a user does an update the transaction commits and releases its locks when the program executes
    <%stmt.executeUpdate("commit!"); %>
    I need to put a break in to stop the program executing this statement, to illustrate the lock is set correctly.
    I have tried to put in an alert box but this does not prevent the rest of the java code being executed.
    I have tried to use prompt boxes, JavaScript functions, but these functions cannot have any java code in them.
    I have tried using the java.swing JOptionPane boxes but this didn?t work either
    I have tried to get input from the user but I don?t know how to retrieve this data on the same page. (As far as I know you have to use submit and even refresh the page or retrieve it on the next page).
    Does anyone know how I can stop the execution on a JSP page and start it again (on same page)
    Mette

    I already have another client (Tomcat jsp application) running and it throws a SQLException correctly when I don�t put in a commit=true statement and don't close the database connection.
    But the problem is how to get the code above to stop to illustrate I have set this lock.
    I have tried to use the JOptionPane but because my program is running in a web browser I cannot use the JOptionPane dialog box.
    I have tired using an alert box but it executes the commit statement before the alert box is dispayed. So this does not work
    While (i < 2)
    if( i==1)
    %>alert(�The transactions commits when you press Ok�); <% //what it to stop execution here
    else
    stmt.executeUpdate(�commit�);
    I am not using threads so I cannot use the sleep function.
    I am using mysql and have already configured it to detect deadlocks and how long to wait for locks.
    Thanks for your help

  • Error while trying to open the same JSP page.

    Hi partners,
    After solving some issues with JSP deployment, we are getting another error message.
    This is when we try to open the same JSP page at the same time.

    I mean this is a concurrency problem.
    Any information about this will be really appreciated.
    Best regards!!!!!
    Francisco Mtz.

    After running the BI_Checkconfig tool I got an inconsistent OLAP API Metadata
    result, it was because a partner was modifying the OLAP metadata without saving
    the changes.
    After saving the changes in the OLAP metadata, I ran the BI_Checkconfig tool
    again with success (no metadata errors).
    Now the pages are displayed without any error message.
    Best regards!!!!

  • More than one business component (views) in the same JSP page

    Hi, I am trying to have more than one business component (views) in the same JSP page as Input Form.
    For example:
    There are two BC4J:
    Person:
    Code.
    Name.
    Address:
         Person_code
         Street.
         City.
    There is a master detail relationship between them and there is a link between both views in the application module.
    I want to create a JSP page with an Input form for both views. When the user decides to create a Person, I need to insert in both tables.
    Insert code and name into Person table.
    Insert Person_code, Street and City into Address table.
    It is possible to do in Forms but I am not sure if I can be able to do this in JDeveloper 10G.
    Thanks

    Sorry I lost the tabs
    Person has two attributes Code and Name.
    Address has three attributes Person_coden Street, City.

  • I want to post the values of the form in the same Jsp Page

    I want to post the values of the form in the same Jsp page.

    Was that a question? Or are you just informing the world of your grand intentions?
    But yeah, all you need to do is direct your action to the same page you're in. So, if this is your foo.jsp, it'd be something like...
    <%
    if(request.getParameter("bar") != null) out.println("Hello");
    %>
    <form method="post" action="foo.jsp">
       <input type="text" name="bar" value="baz">
       <input type="submit">
    </form>When you submitted your form, it would post the value to the same JSP page as you're already in, and print out Hello to the screen. "Hello" would not print out on the first visit, as the request would obviously not contain the parameter "bar" yet.

  • Dynamicaly populating textbox in same same jsp page

    hi,
    i have a list box like
    <select name="ss">
    <option value="1">one
    <option value="2">two
    <option value="3">three
    </select>
    if i select "one" from list box than two text should be populated in same jsp page.
    please tell me how to achive this.

    It isn't a disturbance, it just looked different then what it is.
    My favorite way of doing this is to create the three text boxes, but hide two of them (and disable them). Then use the javascript function to show and enable them... like this:
    <html>
    <head>
    <script type="text/javascript">
      function showBoxes() {
        selectElem = document.getElementById("ss");
        selectedValue = selectElem.options[selectElem.selectedIndex].value;
        text2 = document.getElementById("text2");
        text3 = document.getElementById("text3");
        if (selectedValue==1) {
          text2.style.display = "none";
          text2.disabled = "disabled";
          text3.style.display = "none";
          text3.disabled = "disabled";
        if (selectedValue==2) {
          text2.style.display = "inline";
          text2.disabled = null;
          text3.style.display = "none";
          text3.disabled = "disabled";
        if (selectedValue==3) {
          text2.style.display = "inline";
          text2.disabled = null;
          text3.style.display = "inline";
          text3.disabled = null;
    </script>
    </head>
    <body>
    <form>
    <select name="ss" id="ss" onchange="showBoxes();">
      <option value="1" selected="selected">One</option>
      <option value="2">Two</option>
      <option value="3">Three</option>

  • Can't update the info for my music (e.g., artist names, ratings) on iTunes anymore.

    I used to be able to update the info for my music (e.g., artist names, ratings) via iTunes, but it doesn't work anymore. In the past I'd change it in the music tab underneath my phone's tab. Using one band as an example, it's all spelled exactly the same on my computer in both music tabs (under my phone and on my computer), but it has various spellings still on my phone. Also, when I rate a song on my phone, it no longer shows when I plug into iTunes. I rate songs 1 star if I want to delete them later but it just doesn't work anymore. How can I fix this? Thanks in advance.

    I agree that it should work. But for some reason it does not.
    Suggestions here -> http://www.apple.com/feedback/
    However, I don't understand why you want to keep songs with incorrect info and then correct them on the phone every time you add them to the phone. Most people would want to do it one time.

  • How to print new line in jsp page

    hi
    how to print new line in jsp page
    thanks

    \n - new line character is in java specific not HTML
    specific.Well, if the correct line separator sequence (by far not always \n) would be used, it does add a new line to the HTML output. Too bad that you don't want to see HTML but formatted text. The BR tag is a formatting element for the displayed text, not a line break in HTML. ;)

  • Two managed beans in same jsp page

    Hello
    First this could be a stupid question, but i just can't find a solutions on this problem.
    I wondering that could it be a two managed beans in same jsp page, here is a example:
    index.jsp
    <t:commandLink disabled="#{listBean.currentPage == 1}" id="previous2" type="button" immediate="true" style="font-size:small" action="#{listBean.previousPage}">
    <h:outputText value="Edellinen" id="prev"/>
    </t:commandLink>
    <t:commandLink disabled="#{listBean.currentPage == listBean.totalPages}" id="next2" type="button" immediate="true" style="font-size:small;" action="#{listBean.nextPage}">
    <h:outputText value="Seuraava" id="next"/>
    </t:commandLink>
    then i have a dataTable like this:
    <t:dataTable value="#{customerListBean.customerBeans}"
    binding="#{customerListBean.dataTable}" preserveDataModel="true" style="text-align:left">
    My problem is that when i push a commandLink it doesn't refresh a dataTable. Does anyone know a solution here or is this just a impossible way to do it?
    Thanks for help.

    when i push nextPage (commandLink) it's call action
    and count a new range of dataset and after that it's
    calls a method which is declared on subClass and that
    method get a new data of database on given params.
    and put it on DataTable.
    So listBean is upper class and customerListBean
    extends on ListBeanNo, it doesn't work that way as you expected. You have created two independent instances. They doesn't communicate automatically with each other or so. Just use one CustomerListBean instance and call the inherited methods of ListBean on the #{customerListBean} managed bean instance.

Maybe you are looking for
