Jsf Ajax integration

hello All
Has anyone come across the issue with JSF ajax integration in JSF 2. When I try to use jsf 2 F:ajax TAG i GET THE following error
JSF1064: Unable to find or serve resource, jsf.js.xhtml
Thanks for your help
Nek

Unfortunately you are not giving us enough information. How are you using the tag?

JSF/Ajax adoption in the industry

All,
We have been using JSF/Ajax since last couple of years. What I wanted to find out from the user community in this group is ,
- how is JSF, Ajax combination being adopted in the industry?
- What do experts see as the growth for JSF?
- Are organizations spending time/money in training their in-house resources?
Regards,
Praveen

I'm waiting for the offer to learn how to say NO! without hurting feelings ;)

Problem with JSF AJAX portlets

I am seeing the following issues with JSF portlets
1) When you AJAX enable the portlet, they will not work. There are some javascript errors on the component we are using. They work fine if we don't AJAX enable them
2) I had 2 portlets. 1 JSF and 1 pageflow portlet. If I click on a link in pageflow portlet and after the page gets refreshed, nothing will work in JSF potlet. Again javacript errors
If we had only 1 portlet on the page, JSF portlet works fine
Do you think the prototype javacript library used in the portal causing any issues?

I tried with <naming:namingContainer> immediatly after the f:view tag , but still getting same errors
I am psoting the generated html and javascript error

JSF AJAX post-back

I have a javascript function for a POST request from XMLHttprequest object.The post-back is handled within the decode function of the component which generates the AJAX request. The javascript request looks as follows:
function lookup(field) { .... if (window.XMLHttpRequest) { req = new XMLHttpRequest(); } else if (window.ActiveXObject) { req = new ActiveXObject("Microsoft.XMLHTTP"); } var formdata = "ajaxreq=true"; " var formAction = window.document.forms[0].action;\n" + "req.open(\"POST\",formAction,true);\n" + "req.setRequestHeader(\"Content-Type\",\"application/x-www-form-urlencoded\");\n" + req.onreadystatechange = processXMLResponse; req.send(formdata); } This request is generated from within the directoryBrowser.jsp itself. This request is not being recognized as a post-back by the JSF framework ,successful as it is not causing the decode method of the component to be executed. What is wrong? When i print out the responseText of the request object from the callback function, i get teh html of the page printed out.The responsexml is null.

Maybe, you've already solved the problem.
Anyway, I faced with a similar problem and (after days of debugging and googling) I solved it making the request object local rather than globa (and changing the request callback accordingly)l.
function sendRequest()
var req = createRequestObject(); // e.g. new XMLHttpRequest();
req.open('GET', url, true);
req.onreadystatechange = function{ handleRequest(req); };
req.send(null);
function handleRequest(req)
if (req.readyState == 4)
if (req.status == 200)
// request done
}Hope this help!!
PS: I would thank the guys that made me see the light: [Ajax: The Basics (Part 1)|http://courses.coreservlets.com/Course-Materials/pdf/ajax/Ajax-Basics-1.pdf]

Facelets and jsf-extensions problem.

I'm fairly certain I've run into a problem between facelets and jsf-extensions. I'm working with JSF 1.2 RI, Woodstock, Facelets 1.1.13, on Tomcat 6.
When trying to get Woodstock autoValidation to work I get a javascript error the "I has no properties". The error occurs in the com_sun_faces_ajax.js file in the jsf-extensions-dynamic-faces-0.1.jar (I've used both the RC4 and a build today ,10/18/07 from source with the same results). Here is the code snippet where it happens (with my comment).
var I = G.getElementsByTagName("components")[0];
var C = I.getElementsByTagName("render");
for(var F = 0; F < C.length; F++) {
In the second line there it looks like the variable I is null, but based on the post response below I don't know why.
The response from the post looks like this:
<partial-response><components><render id="PayableForm:vendorGci"><markup><![CDATA[{"valid":true,"id":"PayableForm:vendorGci"}]]></markup></render></components>
However the server side code (validation method) never gets executed. I'm willing to do some digging and debug work, but I'd need to be pointed in the right direction.
The following is more potentially useful code snippets.
Here is the textField code:
<w:form id="PayableForm">
<w:textField style="display:none;" />
<w:message for="vendorGci" />
<w:label id="vendorGciLabel" for="vendorGci" text="Vendor: " />
<w:textField id="vendorGci" autoValidate="true"
text="${vendorBean.searchGci}" maxlength="8" required="true"
validatorExpression="#{ vendorBean.validateVendor}" />
Here is the javascript in the page (the init function is called from the body: onLoad="setTimeout('init();', 0);" , this does happen):
<w:script type="text/javascript">
function VendorListener(){
function VendorNotify(props){
alert("VendorNotify called!"); <--------------- I never see this alert message
if ( props.id != "PayableForm:vendorGci") { return; }
var field = document.getElementById("PayableForm:vendorGciLabel");
field.setProps({
valid: props.valid
VendorListener.prototype.notify = VendorNotify;
function initAccountRows(){
var table = document.getElementById("PayableForm:vendorAccountTable");
table.initAllRows();
function init(){
initAccountRows();
var listener = new VendorListener();
dojo.subscribe(
webui.suntheme.widget.textField.event.validation.endTopic ,
listener, listener.notify);
Here is the validator method. It currently doesn't do anything, just trying to get something to work. I never see the output, and I never hit the breakpoint in the method.
public void validateVendor(FacesContext context, UIComponent comp, Object value){
System.out.println("**********************************");
System.out.println("validateVendor called");
System.out.println(value);
System.out.println("**********************************");
}

Actually I don't need a global variable. I need to refer in my included template the actual backing bean used in the current page. As all my backing bean extends a abstract class I could bind my component to a property of the current backing bean, no matters which one. Just like a polymorphic call but without the parameter. Let's imagine I could get this object of the facesContext object I would be able to do:
<rich:datascroller renderIfSinglePage="false" align="right" for="listagem" maxPages="12" fastStep="10"
pageIndexVar="pageIndex" pagesVar="pages" stepControls="show" fastControls="hide" boundaryControls="show"
inactiveStyleClass="paginacaoInativa" selectedStyleClass="paginacaoSelecionada"
styleClass="paginacao" tableStyleClass="paginacaoTabela"
binding="#{facesContext.currentBackingbean.formDataScroller}" id="paginacao">
Instead of pass the backing bean to the ui:param of this template... Dou you get the point?

Ajax problem in IE7 - get.get() is empty

I am testing Ajax under Mozilla Firefox and IE7. Under Firefox is everything fine but IE7 gives me errors.
My process is the following:
declare
l_counter number;
l_o_name varchar2(2000);
begin
owa_util.mime_header('text/xml', FALSE );
htp.p('Cache-Control: no-cache');
htp.p('Pragma: no-cache');
owa_util.http_header_close;
htp.prn('<select>');
htp.prn('<option value="x">x</option>');
htp.prn('</select>');
debug.add('ok');
end;
debug_add('ok') adds text 'ok' into debugging table. I can see that this info is being inserted into the table, so the process runs through.
My JavaScript is in ApEx page attributes "HTML header" section and is like the following:
<script type="text/javascript">
function get_AJAX_SELECT_XML(pThis,pSelect){
     var l_Return = null;
     var l_Select = html_GetElement(pSelect);
     var get = new htmldb_Get(null,html_GetElement('pFlowId').value,'APPLICATION_PROCESS=my_proc',0);
     get.add('GTEST',pThis.value);
alert(get.get());
     gReturn = get.get('XML');
     if(gReturn && l_Select){
alert('Never here in IE7');
          var l_Count = gReturn.getElementsByTagName("option").length;
          l_Select.length = 0;
          for(var i=0;i<l_Count;i++){
               var l_Opt_Xml = gReturn.getElementsByTagName("option");
               appendToSelect(l_Select, l_Opt_Xml.getAttribute('value'), l_Opt_Xml.firstChild.nodeValue)
     get = null;
function appendToSelect(pSelect, pValue, pContent) {
var l_Opt = document.createElement("option");
l_Opt.value = pValue;
     if(document.all){/* why is ie different ask bill */
          pSelect.options.add(l_Opt);
          l_Opt.innerText = pContent;
     }else{
          l_Opt.appendChild(document.createTextNode(pContent));
          pSelect.appendChild(l_Opt);
</script>
alert(get.get()); gives me popup with text "undefined" in IE.
So "if(gReturn && l_Select)" will never become true.
I call it in an item:
onchange="get_AJAX_SELECT_XML(this,'P3201_XXX')"
In Mozilla 2.0.0.7 everything works, i can get correct answer from get.get() and the list is being filled with "x".

Hi,
I'm having a sporatic problem.
Where do you put the encoding?
Content-type: text/xml; charset=UTF-8
Cache-Control: no-cache
Pragma: no-cache
<?xml version="1.0" encoding="UTF-8"?>
I have the following in my ODP function
owa_util.mime_header('text/xml', FALSE );
htp.p('Cache-Control: no-cache');
htp.p('Pragma: no-cache');
owa_util.http_header_close;
then I start my select list:
     htp.prn('<select>');
     htp.prn(ls_default);
and a loop to build the option code

MAC OS/X JSF "hang" problem in 10.1.3 preview

I'm experiencing some really odd delays in JDev 10.1.3 on my Mac:
Machine Name:     PowerBook G4 15"
Machine Model:     PowerBook5,6
CPU Type:     PowerPC G4 (1.2)
Number Of CPUs:     1
CPU Speed:     1.5 GHz
L2 Cache (per CPU):     512 KB
Memory:     1 GB
Bus Speed:     167 MHz

State:     Enabled
Version:     1.0
System Version:     Mac OS X 10.4.2 (8C46)
Kernel Version:     Darwin 8.2.0
The problem only seems to occur with JSF projects. When I switch from a JSF-JSP document "code" tab to a "design" tab in a project, it takes 60+ seconds... always. The entire IDE freezes up at this point.
I've also noticed the following start-up errors in JDev:
/Users/rhayes/jdevhome/lib/ext/junit_addin.jar!/meta-inf/jdev-ext.xml

Error: <Line 11, Column 14>: XML-24521: (Error) Element not completed: 'extensions'
I have JDev 10.1.2 and 10.1.3 installed on the same Mac with different ".app" extensions. Is this a problem?
I'm running 10.1.3 on WinXP Pro and I don't notice any of these problems...

Doing what you mentioned improves the speed by about 50%.
However, the JSF form then becomes a little more difficult to work with.
Thanks.

JSF Rendering problems

Hello
I have encountered tow problems using JSF 1.0
First:
I have a site that has a css file asociated with it.
In this css file i have a class for the option tag "<option>".
My problem is that JSF dose not provide a way to pass and render the class attribute on the option tag.
Is there a way to render this attribute on the option tag without extending the component or writing a renderer for it?
Second:
How can I pass the attributes colspan and rowspan of a <td> element rendered for a panelGrid tag without extending the component or writing a renderer for it?
Thx.

Hello again
I forgot to mention this for th above problem.
The problem with the option tag is that this jsf code
<h:selectOneMenu id="someId" value="" styleClass="select">
<f:selectItems value="#{Dummy.dummySelects}" />
</h:selectOneMenu>
generates this HTML code
<span class="select">
<select id="someId" name="someName" size="1">
<option value="dummy select">dummy select</option>
<option value="dummy select">dummy select</option>
<option value="dummy select">dummy select</option>
<option value="dummy select">dummy select</option>
</select>
</span>
the class="select" attribute should be on the <select> tag but is on the <span> tag.
Why is this and how can I fix it ?

JSF encoding problem with Russian

Hi,
I am new to JSF, trying to build prototype i18n JSF app with MyFaces 1.1.5
Mostly care about IE6/7, do not officially support other browsers.
I do have resource bundles, it is localized and internationalized.
So user is supposed to work in either English or Russian.
It all works except a few issues:
1) When user enters something in Russian in inputText field on the first page,
trying to pass it to the next page via managed bean.
But instead of showing it in Russian, it shows some garbled text in outputText or outputLabel: Îëåã
FF3 & Chrome show it as: Олег [&#xxxx, where xxxx us a 4 digits]
It does pick up labels from correct bundle on the next page, so locale is changed correctly.
Actually, when I switch locale on the same first page, getting the same problem (after it's refreshed).
Seems to work OK with Spanish
Is that incorrect Cyrillic encoding, JSF encoding or broken Unicode or locale?
How can we fix that ?
Less important issues:
2) When we switch locale (correct values in bundles), on the screen it can not change currencyCode, currencySymbol, TimeZone,
it always shows the first one it picked, although dateTime and Number formatting changes correctly;
3) In IE6 "alt" tag attribute produces garbled characters in Russian (black vertical squares), looks like IE6 bug; FF3 & Chrome work fine.
Please help !
TIA,
Oleg.

For 1, you are not passing the characters in the correct encoding from one page to the next when you pass the parameter (most likely).

It looks Oracle Form/Applet die hard versus J2EE Servlet/JSP/JSF & AJAX

I left the form forum for a while and am busy with transfering our Oracle web forms app to Struts based J2EE application (just because the Oracle EE AS is the moving cause, it's out of my control.). After a year or so on J2EE which I enjoyed the fresh OO coding while keep enhancing Oracle webform app in production, I have some thought on Applet vs J2EE JSP/JSF plus AJAX.
1) JSP itself is hard to avoid the full screen refreshing even though user just does partial changes ,e.g., lists, on the screen, it has to use AJAX to do the tricks. While partial refreshing in applet is natural default behavior.
2) Forms is really an RAD, while J2EE's IDEs does help a bit(IBM's Websphere v6 even called iRAD) which takes way longer programming time compared to Forms. One IBM's article says it trys to win the Oracle Forms developers by giving the familiar graphical way of drag/drop GUI, so IBM recognizes the RAD coding power of Oracle Forms. So, IBM promotes the RAD similar to Oracle Forms.
3) GUI/business rules related validation: Applet offered a great advantage over JSP/ even JSF which to avoid the full screen refresh, AJAX/JavaScript is used heavily. User friendly interaction of applet is way better than J2EE.
4) Browser's back/refresh buttons also are headache to J2EE, expecially we need to support IE and Firefox. Applet basically is not bothered by these buttons.
Recently, I read techi news said that the new chips will make the network transfer speed 10 time faster than now-even the cell phone transfer the image will be way faster. Then I predict the applet, just like IBM's mainframe, will see its Spring again, not like now in its winter. Especially the Oracle Forms makes coding easier than pure applet coding.
Oracle folks, kepp beefing up the Oracle Forms, don't just pay attention to JDev. J2EE IDE, most of all, remove the Oracle EE ASxx block, be open. Oracle EE ASxx is really not a pretty baby, even though so Oracle thinks it is.

1) Why we are transfering your Oracle web forms app to Struts based J2EE application?
Since our corporate is IBM world-DB2/UDB, WebSphere AS (WAS) etc. It only allows Oracle Forms/reports servers to be compatible with the infrastructure. It does not allow to purchase another EE app server(espeically LDAP). We could not upgrade our forms/reports6i to 9i or 10g.
2.Therefore the Oracle EE AS is the moving cause, it's out of my control because I did my best to talk to Oracle sales, but no avail. I am glad that I got a good chance to beef up my J2EE Struts skills.
If extract out the forms/report9i/10g engines from the Oracle EE AS 9i/10g, (don't attempt to bundle sell the EE AS to customers-regardless of the shrinked 9.0.4 forms/reports services version, it's still another EE AS) and make them compatible with other ASs(espcially the LDAP), then Oracle Forms will have more customers.

java.lang.NoClassDefFoundError means that a class can't be found. The class that can't be found is:

So what do you think is the problem?

How to solve Ajax problem in Tomcat server

we are using Tomcat 5.0.27 server and my sql server. we using AJAX Techniques in my projects. but its some times working fine but sometimes not working the code sample is given by
var req;
var names;
function initRequest(url) {
if (window.XMLHttpRequest)
     req = new XMLHttpRequest();
else if (window.ActiveXObject)
isIE = true;
req = new ActiveXObject("Microsoft.XMLHTTP");
if (req==null)
          alert("Your browser does not support XMLHTTP.")
function loadPurchase(startLetter)
     var mon=document.getElementById('month').value;
var yea=document.getElementById('year').value;
var url = "../inventory?actionS=INVPurchase&month="+escape(mon)+"&year="+escape(yea)+"&id="+escape(startLetter);;
     initRequest(url);
     req.onreadystatechange = PurchaseRequest;
     req.open("GET", url, true);
     req.send(null);
function PurchaseRequest() {
          0 (Uninitialized) The object has been created, but not initialized (the open method has not been called).
          1 (Open) The object has been created, but the send method has not been called.
          2 (Sent) The send method has been called, but the status and headers are not yet available.
          3 (Receiving) Some data has been received.
          4 (Loaded) All the data has been received, and is available
alert(re.readyState)
     if(req.readyState == 4)
alert("Inside Ready State");
document.getElementById('Edit').disabled=true;
document.getElementById('Delete').disabled=true;
if (req.status == 200)
PurchaseMessages();
     else
          alert("Problem retrieving XML data")
function PurchaseMessages()
var batchs = req.responseXML.getElementsByTagName("purchases")[0];
var str="";
for(loop = 0; loop < batchs.childNodes.length; loop++)
var batch = batchs.childNodes[loop];
var Refid = batch.getElementsByTagName("Refid")[0];
str = str +Refid .childNodes[0].nodeValue;
var tb=document.getElementById('PurchaseTable');
tb.innerHTML=str ;
the alert coding( req.readyState) is always 1
how to solve for that
please any one help me

Sorry, I've never done this. I went to the Tomcat site and pulled down the CGI docs, which you might have seen:
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/cgi-howto.html
No other help available from me. Sorry.
