How to call the form bean value on jsp withthe help of jstl tag

hi
all friends
i am working in struts & i use jstl tag in jsp. i have one problem rise is how to call the form bean value in jsp page by using jstl tag.
i now how to retrive the value through jsp:logic
eg. <logic:empty name="userListForm" property="users">
NO USER FOUND
</logic:empty>
see * userListForm mean formbaen name.
* users means collection object.
so how can i write above e.g in jstl

You use the jstl core:if or core:choose combined with the EL:
<c:if test="${empty users.userListForm}">
NO USERS FOUND
</c:if>I suggest you lookup the jsp expression language (EL) using google, it's very powerful.

  • How to clear the Managed Bean Values prior to load a JSF page

    Hello.
    I have a jsf page that contains fields that need to be cleared BEFORE the page is loaded.
    My managed bean where the fields are linked (I�m using the value attribute) is in the SESSION scope because I need to control they values across a popup window and if I use request scope, my vectors that load objects like dataTable are cleared when I post the form.
    My question is :
    How I CLEAR all the values in the managed bean BEFORE the page is loaded ???
    In the WebForms (Microsoft .NET) I have an method on the codebehind called Page_Load where I put my initialization code for my page.
    Thanks in advance.
    Rog�rio

    Rog�rio,
    You can do this with a PhaseListener. Just regiser a new listener for the RESTORE_VIEW phase, and implement the beforePhase method; you can do this in the backing bean's constructor, or somewhere elase. This is pretty much the same as the Page_Load event handler in .NET.

  • How to call the backing bean method through javascript by closing window?

    Hi all,
    What I want to do is:
    I open a new page by clicking <t:commanLink.../> from the first page. Then I close the new page. By closing the new page I will call a function in the backing bean such as myBean.doSomething() to do something. Such like:
    <body onUnload=jsFunction()..../>
    ...

    So far I understand, I should write following code
    in my second page:
    <html>
    <head>
    <script type="txet/javascript">
    function jsFunction()
    {>
    ocument.forms[0].action="#{myBean.doSomething}";
    document.forms[0].submit();
    </scrip>
    </head>
    <body onunload="jsFunction()">
    <ui:composition>
    <h:form id="myForm">
    <t:commandLink id="myLink" immediate="true"
    action="#{myBean.doSomething}"
    value=""></t:commandLink>
    </h:form>
    </ui:composition>
    Is that right? I am not sure if I've the javascript
    in the right position.I am sorry! That solution will not work. My Bad.
    You can try this.
    1) Have a invisible command button on your first page with the action attribute set to "#{myBean.doSomething}" as below
    <t:commandButton style="width:0px;height:0px" id="myButton" immediate="true"
    action="#{myBean.doSomething}"
      value=""></t:commandButton>2) Your JS onunload method on the second page should look like
    <script type="txet/javascript">
       function jsFunction()
    var buttonObject= window.parent.document.getElementById("formname:myButton");
    buttonObject.click(); // This would help in submitting the first page
    // to submit to the needed action method
    </script>Karthik

  • How to Supply the form field values to a pdf form when loading it

    I am working on a web site project using Asp.net where the user has to fill in a PDF eform in acrobat reader. Then when he clicks on submit it returns to my asp.net app and the PDF form supplies the values back to my asp.net app. So my asp.net app has the values that were filled in the PDF form and can save those values and work with them...
    OK.
    What I need to know is when I am in my asp.net app, and the user wants to go back and reopen the same form, from my asp.net app..... then how do I pass back the values that were saved back to the PDF form??
    I know if I had a way to pass the values to the PDF form in some way then in the Doc.open or doc.load event of the form I could easily write a little javascript to plug in the values in the PDF form fields.
    but how do I pass those values from my asp.net app to my PDF form???
    thanks

    Thanks bcweed for all the info. I fixed my problem, it had something to do with LiveCycle Designer. If I just use Acrobat to add the form fields, then the FDF works fine. As to your situation with the SavToBuf, that happens to be the method that I am using, so I will just post my code here, and maybe you can pick out what is different from yours. The Response.BinaryWrite(FDFin.FDFSaveToBuf)is at the bottom.

    Hi all,
    I am trying to refresh the data that have been retrieved from database to a jsp page. The first action class is retrieving data from database and display them in the jsp page.

    so now you will have 2 fields.
    iam considering it as for ex: field1 & field2

    e_dynpfld_mapping-dyfldname =   -
