In a scenario like when user changes the item in dropdown box. label name as to change for the next text box.
-----JSP page------
h:outputText value="*" styleClass="mandatoryField" />
<h:outputText value="Matching Criteria:" />
<h:selectOneMenu id="MatchingCriteria" styleClass="dropDownMenu" value="#{OffsetTradingRuleBean.matchingCriteria}"immediate="true" onchange="unitChange()">

-----Java Script-----
function unitChange(){
     if(document.getElementById("frm:MatchingCriteria").value!="1"){

balu
actually i want to swap label name using javascript. first i will call onchange event from matching criteria dropdown box . then it will fire unitChange() function.
then i am putting value Deminimis dollor or deminimis shares accroiding to the value which is there in dropdown.
this value as to come in <h:outputText id="deminimisLabel" value=" should come value from java script" />
and it should act dynamically ,. like when ever user changes the dropdown item . the corresponding name should change in lable name.
thanks

How to invoke javascript function after business action??

How to call javascript function(such as "window.close(), window.open(...),...") in the action method(public String doBusiness(){...}) of <h:commandButton>?If not,then,is there any alternate approach to call javascript function when the bussiness action method finished??
Thanks a lot!

Since your business method is called after the form is submitted, and your code is running on the server, probably the only thing you can do is this:
Create a custom component (Maybe call it the "onLoad" component) that you always render at the top of your JSP. In the regular situation it wouldn't render anything, but in the case you mention, after your busines method, you would call a method on this new component on the server that would cause it to actually render something the next time it is rendered. When rendered this time, it could then render the "onLoad" method which has your window.close() code in it. The window would then close right away.
The key is that you are not doing any of this on the client. The form is submitted, your business logic is executed, then the next page is rendered. When the next page is rendered, your javascript could be rendered to close the window.
If I'm offbase here, someone please say something, I'd hate to send this guy on a wild goose chase.

How can I pass a value into a page fragment?

How can I pass a value into a page fragment?
I am implementing four search screens. And the only thing different about them will be their backing bean.
So I’d like to do something like have four pages, each which retrieves its appropriate backing bean, sets that bean to a variable, and then includes a page fragment which contains the generic search page code (which will make use of that variable).
The code in the four pages would be something like this:
<?xml version='1.0' encoding='windows-1252'?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.0"
xmlns:c="http://java.sun.com/jsp/jstl/core">
<jsp:directive.page contentType="text/html;charset=windows-1252"/>
<c:set var="searchPageBackingBean"
value="#{pageFlowScope.employeeSearchPageBean}"
scope="page"/>
<jsp:include page="./SearchPageBody.jsff"/>
</jsp:root>
At this point, what I’m seeing is that the fragment page, SearchPageBody.jsff, has no visibility of the searchPageBackingBean variable, either referencing it as #{pageFlowScope.searchPageBackingBean} or just #{searchPageBackingBean}

The following will work, assuming you are needing to access a managed bean:
Put this in the parent page:
<c:set var="nameOfSearchPageBackingBean"
value="employeeSearchPageBean"
scope="request"/>
Put this in the child, SearchPageBody.jsff:
<c:set var="searchPageBean"
value="#{pageFlowScope[nameOfSearchPageBackingBean]}"
scope="page"/>

How do i use Connection pool in JSP pages

Hey everyone,
I am using a connection pool in my web application. I am using DbConnectionBroker from Javaexchange.com. It has a class that creates a connection pool available for the servlets. I am trying to figure out that how to use connection pool within the JSP pages if I want to connect to the database. In the servlets i am using DBConnectionBroker pool = (DbConnectionBroker) getServletContext().getAttribute("dbPool") to get database connection. How Can i use this in JSP page to get a db connection.
Thanks

If the reference to the connection pool is already stored as an ServletContex attribute, try:
<jsp:useBean id="dbPool" scope="application" class="com.javaexchange.dbConnectionBroker" />
<%
Connection con = dbPool.getConnection();
%>

How to get the value retruned by java script function into my jsp page

Hai all,
I had a particular java script function which returns a date.
function getDate() {
var sDate;
// This code executes when the user clicks on a day in the calendar.
if ("TD" == event.srcElement.tagName)
// Test whether day is valid.
if ("" != event.srcElement.innerText)
//alert(event.srcElement.innerText);
sDate = document.all.year.value + "-" + document.all.month.value + "-" + event.srcElement.innerText;
document.all.ret.value = sDate;
var mahi=window.open("configurexml.jsp?xyz=document.all.ret.value")
return sDate;}
Now i want to display this particular date in my jsp page. can anyone tell me the correct approach or a sample code to diaplay this date in my jsp page.

<form name="f1">
<b>20 october 2006 </b>
Here where i am printing the date i had to get the value from the js function. how to do that. plz help me....

Are you talking about server-side java code (servlets/jsp) or client side (applet)? Given we are in the JSP forum I'll assume we're talking server side.
If so, you are making a common but fundamental mistake. JavaScript executes on the client, not on the server. If you want client data on the server it has to get there somehow. The simplest way to do this in JSP land is via HTTP. So... have your JavaScript code call a JSP (or servlet) and pass the value you want as a URL parameter. Of course this will also change the browser location, so if you don't want this to happen use a frame or iframe to capture your HTTP request.
For example:
Javascript....
function someFunction() {
return 1;
var value = someFunction();
location.href="somejsp.jsp?value=" + value;

How to use value returned from a bean in jsp page

Hi All,
I have a string array value being returned from a javabean to a jsp page. I want to be able to assign the value to a variable in the jsp page.
How do I do this?
Many thanks :)

thanks for your response.
I actually used something like this:
<% String loggedin = log.User(user,password);
out.println(loggedin);
%>i am not yet as much of an expert on beans as i would like to be, but i thought it is not really a bean if it has a getter method which takes arguments?
