Include jsp/jsf code in a jsf page at runtime

Hello,
I have a problem. I must get data from a Firebird db. The data is posted in jsp/jsf
code. I've tried to get them through a servlet. The problem is that when I include
result in my jsf page, the code doesn't get compiled.
If I include code with a <h:outputText> or a jsp action <jsp:include> or a <c:import
url> the code doesn't get compiled. If I include code with directive <%include> it is
translated correctly, but include directive accepts only physical files.
Any suggestion?
Thanks

Is it possible to use two diff forms in same jsp/jsf page?

Hi all,
My requirement is to submit the form based on selection of radio button.
since half part needs to be jsp based which is not using any tags etc.
But i am trying to use some jsf based component which requires to be inside <f:view><h:form> of
<%@ taglib prefix="f" uri="http://java.sun.com/jsf/core" %>
<%@ taglib prefix="h" uri="http://java.sun.com/jsf/html" %>
i.e. some <c:comboBox>
</h:form> </f:view>
Now earlier i was submitting the form as
<form action="/techstacks-v2_1/reportAction.do" method="post" name=doSearch id='doSearch'>
But now i found, in order to use combo box component which is entirely jsf based i need to use <f:view><h:form> which is kind of taking over the previous form submission mechiansm.
I am trying to keep them separate as two differnt forms.
one entirely jsp based and other as jsf based.
Now my question is can i use such way of doing so or is there any better way of implementing so.
My friend suggested that i can pass the value of jsf based form in hidden form to a input box of form to be submitted finally instead of submitteing two diff forms.
but in that case also i ahev to use two forms in a single jsp/jsf page.
suggest me something which can really work out.
thanks

You can use as many forms as you want as long as you don't nest forms. The HTML spec probibits that.

How can I include a jsf page?

I need to include a jsp page that contains jsf code, I try with:
<c:import url="faces/include.jsp" var="prova" />
but the server response:
javax.servlet.ServletException: Cannot find FacesContext
There something that is wrong?
Thank's
Teo

I read the document but is not my case.
My java server faces works well until I put the tag
<c:import url="./include.jsp" var="jsf" />
from tag library, ans I don't know why
Thank's

Including a jsf page into simple jsp

hey i m including a xhtml i.e facelet into an jsp file.till this scenarion it is working fine but when i am including that page into another jsp page it is not showing the correct representation of the jsf components

I know it is frustrating to have a problem, but read your own question and ask yourself this: can anybody help me with the information I am giving here? I hope you can reason for yourself that this is simply not true, no matter how much you want it to be.
You'll have to dig deeper yourself until you can either solve it, or unearth more information that might allow people to help you.

Access Java class in my JSP/JSF page and conditionally open a new browser

When the user clicks on a button in my JSP page, I'd like to launch a new browser and display certain things in that browser window while leaving the original browser window open.
My thought was to invoke a javascript method in 'onLoad' which would determine if the new window needs to be launched.
This is kinda what my page looks like:
<jsp:root version="1.2" ................>
    <jsp:directive.page import="java.util.*, com.test.Configuration" contentType="text/html;charset=UTF-8" pageEncoding="UTF-8"/>
    <f:view>
     <ui:body binding="#{Page1.body1}" id="body1" onLoad="launchWindow();">
     </ui:body>
   </f:view>
   <script type="text/javascript">
        function launchWindow(){
         if (Configuration.openWindow()) {
          window.open("hello.jsp", "newWindow", 'toolbar,width=400,height=400');
    </script>
</jsp:root>My problem is that the call to "Configuration.openWindow()" does not resolve correctly. If I remove that call and simply make a call to "window.open()" all works. But once I put the condition in, nothing happens. I do not see an exception in my browser window but a new browser window does not open.
Is my syntax correct. Can I make a call to the static method 'openWindow()' in my class 'Configuration.java'.
thanks,
tsc

I have made some changes so that I do not directly access the 'Configuration' class in my javascript.
I have a hidden field on my form and when the user clicks the button, in my back bean, I set a value for the hidden field. In the javascript function 'launchWindow()' I check if a value has been set for the hidden field and if yes, I open a new window.
<ui:body binding="#{Page1.body1}" id="body1" onLoad="launchWindow(document.forms[0]);">
<h:inputText id="hiddenField" value="#{formBean.hiddenValue}" />
<script type="text/javascript">
        function launchWindow(form){
            alert("in lw");
            var test = form["form1:hiddenField"].value;
            alert("got test");
            if (test != "")
                window.open("hello.jsp", "newWindow", 'toolbar,width=400,height=400');
            alert ("done test");
</script>When my page is first loaded, the launchWindow() is called and all the alerts popup as expected.
When I click on the button (the back bean sets the value on the hidden field), my page is reloaded but this time its blank.
Any ideas as to why this maybe the case?
thanks,
tsc

Re-rendering JSP/JSF pages

I wnat to be able to set up a checkbox that will cause some other components to be visible or invisible. I was thinking of using the rendering attribute on the target components. However, I am having trouble finding a good method of causing the rendered attribute to be re-evaluated when the checkbox is clicked. This is an enhancement to a current applicaiton that uses JSF1.1 with Tomahawk.
Any help would be appreciated. I've put in several hours researching this and have not found anything helpful.
Mike

Just let the checkbox submit the form on click.
<h:selectBooleanCheckbox value="#{myBean.checked}" onclick="this.form.submit();" />
<h:someComponent rendered="#{myBean.checked}" />If you want to do this asynchronously, consider Ajax4jsf.

JSF page shows runtime error when application deployed in local oc4j server

I developed a wsrp portlet producer based application and delployed it in oc4j application server. But when I open input.jsp page url which has JackBe portlet mashlets on it in web browser.
I get an error 'mdsId=/oracle/adf/portlet/wsrpPortletProducer1_1223631729156/ap/E1default_e62a8fe5_011e_1000_8002_ac144d7e5e23.pxml not found'.
Oc4j, oracle database instance and JackBe presto are running on same local machine.
I am using trial version of JackBe presto. Similarly while installing oc4jpdk, I do need to change ORACLE_HOME path to oc4j from oracle database folder which stops running of my oracle database(Oracle10g) instance on my machine. Please suggest me with possible solution pointers to resolve it.

Hi
Thanks for the input. I checked at the forum you referred to. I did not find any similar question discussed on the forum. I highly appreciate if you suggest me few exact pointers to this issue. I am losing on time and appreciate quick response.

Embed a jsf page in a jsp page -

Is there some way to included a jsf page inside a jsp page and code form action correctly ?
In my JSP page I have the following:

The page loads correctly, however, when I submit the form I get "Cannot find FacesContext"
The way I'm coding form action in my JSP <form method="POST" action="../common/controller.jsp">
The way JSF generates <form id="utform" method="post" action="/riskdb/user/unMapTrans.jsp" enctype="application/x-www-form-urlencoded">
The JSP is another location than the JSF being called... http://localhost:7001/riskdb/common/controller.jsp

(1)Rewrite your jsp to a new jsf and use <f:subview> for jsp:include action.
(2)Rewrite your jsf action to produce a non-jsf response.

Newbie Alert: How can I include a JSF in a JSF

Sorry for what must be a really stupidly easy question but I have tried every way I can think to get one JSF page to include another JSF page. For instance I want to include a standard site wide header. I am using jspx and have tried
<f:subview id="header">
    <jsp:include page="header.jsf"/>
</f:subview>and
<f:subview id="header">
    <c:import url="header.jspx"/>
</f:subview>and every variation you can imagine (both .jsf and .jspx extentions, with and without a rendered property on the subview, including everything in the included page in f:verbatim and a million other things). My header page is as simple as <?xml version="1.0" encoding="UTF-8"?>
<jsp:root version="2.0"
     xmlns:jsp="http://java.sun.com/JSP/Page"
     xmlns:c="http://java.sun.com/jsp/jstl/core"

HTML markup for JSF page

I have a JSF page containing both standard JSF components and custom components. In the page am able to trigger AJAX requests,capture the requests in phaselistener. Now what I want is to generate output for a particular div inside the whole page. This div in turn contains a JSF page. The HTML markup corresponding to the page has to be sent to the browser.
(i.e) I need a mechanism wherein I can specify the name of JSF page,get the HTML markup for the same and send it across to the browser as response. Please guide me as how to go about it.

Its been a week since I posted this query.Still no replies. Let me make myself clear.
Suppose am having
<h:panelGroup id="outerDiv">
                 <h:panelGroup id="innerDiv1">
                                <jsp:include > //Includes firstpage-JSF page
                  </h:panelGroup>
                  <h:panelGroup id="innerDiv2">
                                <jsp:include > //Includes second page-JSF page
                   </h:panelGroup>
</h:panelGroup>I want to send an AJAX request,fetch corresponding HTML markup for the JSF page I have included and use it in javascript to write to the <div>. So is there any mechanism wherein I can give the name of the JSF page, get the corresponding HTML markup? If not, is there any workaround? I dont want to use any third-party components.

JSF page 'Initial load' problem

I've found several threads touching on this already, but none seem to have a solution.
When JSF loads a JSP page for the first time, it goes through the restore view phase which creates an initial view (as there isn't a current one to restore). It then goes directly to the render response phase.
My problem is, I have a JSP/JSF page that I pass paramaters to via html GET. For example:
http://localhost:8080/jsf/region.jsp?locationForm:directorate=1&locationForm=locationForm
Because the first load goes directly to the render response phase, the parsing of these paramaters is never done & the page does not update as expected.
The second time you perform the same request, JSF goes through the standard request processing lifecycle and works as you would expect, setting directorate to 1 in the backing bean and displaying an updated page.
Is there any way to change JSF's default behaviour on a JSP initial load to do the whole lifecycle? Is there another way to get around this, short of loading the page twice to ensure it has the right information in it (which would be quite a hack)?
I need to use html GET (as opposed to html POST) because:
I'm using a technique of a hidden iframe that loads dynamically created javascript to update a dropdown list (DDL) on the main page without reloading the page in its entirity. This is to minimise network chatter as the system will be run on a 56k network. I have an onchange event on my JSF DDL that calls javascript to reload the hidden iframe.

Thanks for the replies.
I tried both of the suggested options
1. If your bean is managed (declared as managed bean in faces_config), you can set the initial value of the property as, for example, #{param.locationFor }.
Unfortunately I can't use this option as the backing bean i'm using has to be session scope. This is because the DDL options are set by the iframe page, not the main page. There could be many request/responses between client/server before the user finally presses the submit button. If I change the backing bean to request scope, I end up getting "Validation Error: Value is not valid" for the DDL because the selected ID is not in the backing bean's list of possible values for the DDL.. #{param} can't be used for session level BBs.
2. If you don't want to use the managed bean properties, you can go get your parameters in your bean's constructor.
I'm unable to use this option either. The backing bean is shared between the main page and the hidden iframe page. When the main page loads, the backing bean's constructor is called but that isn't the time when parameters need to be parsed. When the iframe page is loaded for the first time (via javascript onchange on a DDL on the main page) using http://localhost/iframe.jsf?iframeForm:ddlId=1&iframeForm=iframeForm is when I need to parse the parameters, by which time the backing bean is already instanciated and the constructor has already been called.
I'm looking at where else I could get the parameters other than the constructor. I might be able to do it elsewhere.
My guess as to why the following code works is it's not using a backing bean & isn't updating backing bean values on the first run:
<f:view>
<h:outputText value="param= #{param}"/>
</f:view>To replicate the problem, create a simple backing bean, for example:
public class sample {
    private Integer selectedId
    public String getSelectedId() {
        return selectedId
    public void setSelectedId(Integer selectedId) {
        this.selectedId = selectedId;
}Then create the following sample.jsp:
<!doctype html public "-//w3c//dtd html 4.01 transitional//en">

<%@taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<html>
<head>
<f:view>
<h:form id="iframeForm">
    <h:panelGroup>
      <h:inputText id="selectedId" value="#{sample.selectedId}" />
    </h:panelGroup>
</h:form>
</f:view>
</head>
</html>Then try going to sample.jsp?iframeForm:selectedId=10&iframeForm=iframeForm (Similar to the request my main page is doing via javascript to populate the hidden iframe)
The first time you do this, the text box will be populated with 0 (ie, it skipped the JSF lifecycle and ignored your 10 input). The second time and subsequent times it works as expected, with the text box containing the number 10.

Modifications to JSF page dont show up

I am using JSF 1.1, Tomcat 4.1. I am facing a strange problem. If there happens some error on my jsp/jsf page once and any error message shown. I modify file, fix the problem and again load the page in browser. But the error continues to show as it was on first time. When I view the html source of this file from browser, I am shocked to see that same old html is being rendered. My modifications are not updated in it. First I thought it is due to browser settings, that cached page may be shown, but after testing from other machines it is confirmed that there is some problem at JSF engine level. that it continues to show the initial error prone version of page. I have restarted TOMCAT and even system. But unable to see the modified page.
Please help me for this.
Thanks,
Zahida

You may also clear the session. The error persists even after restarting tomcat because tomcat serialises sessions.
Create a simple jsp page to clear the session:
<%
session.invalidate();
%>

Actions/submitting non JSF forms to JSF pages

Ok, I am new to JSF so bear with me,
I am trying to execute some logic BEFORE displaying a JSP/JSF page - a simple example of this is checking if user is logged in, or getting data for the page based on parameters passed in from a non-JSF page (or on URL line), or deciding which page to display, etc. In other words similar to struts action.
Seems basic but I cant figure out how to do it without placing logic into JSPs. All examples I see seem to require a submit from a JSF page to get to the controller logic. What am I missing?
Thanks.

I decide the struggling is a sheer waste of time and hurts future reusability and maintainability.
Write a set of JSF embedded JSPs from scratch.
Or give a try to: https://facelets.dev.java.net/

Thank you.

Hi,
Can you post the source of the MenuGlobalDynamique.jsp page?
if MenuGlobalDynamique.jsp is a JSF page and you want to include it into other JSF page you must mark out (or delete) this parts from the MenuGlobalDynamique.jsp like here:
<?xml version='1.0' encoding='UTF-8'?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.0"
