Problem with Javascript in JSP

Hi Guys,
I have this problem with my JSP page. I am using a javascript function
which calls a function within a bean. The problem that I have is that I get an error when trying to call the following function :
function refDataTypes_onchange()
Vector empNames = DBQuery.getResult();
I get a runtime error at the line Vector empNames = DBQuery.getResult;
Any ideas would be much appreciated.
Below is the whole code:
Thanks in advance
FRank
<%@ page contentType="text/html;charset=WINDOWS-1252"%>
<%@ page import="java.util.*, java.lang.*" %>
<%-- Declare the java bean for the countries to be queried --%>
<jsp:useBean id="DBQuery" class="DBQuery" scope="page" />
<%-- Bean property searchCondition is not set to query countries --%>
<jsp:setProperty name="DBQuery" property="searchCondition" />
<%
Vector empNames = DBQuery.getResult();
%>
<HTML>
<BODY BGCOLOR="GREY">
<SCRIPT LANGUAGE="JavaScript1.1">
function refDataTypes_onchange()
Vector empNames = DBQuery.getResult();
</SCRIPT>
<FORM NAME = form1>
Please enter in the following details
<p>
Reference Type :::====
<select name="refDataTypes" onchange="refDataTypes_onchange()">
<option value ="1"></option>
<% for(Enumeration enum = empNames.elements();enum.hasMoreElements();)
String nextEmpName = (String)enum.nextElement();
%>
<option value =<%=nextEmpName%>><%=nextEmpName%></option>
<%
%>
</select>
<BR>
<BR>
Emp No
<INPUT TYPE="text" NAME=txtAge >
<BR>
<BR>
<INPUT TYPE="button" VALUE="Check Details" NAME=butCheckForm >
</FORM>
</BODY>
</HTML>

Thanks dimadoo
I need my JSP to do the following :
When a user selects a option from a select list. There is a textfield which I want to populate based on the option that thas been selected from the list.
I tried the following :
<% Vector empNames = DBQuery.getResult(); %>
and it does not even go into the bean.
Will this work if I refresh the page?

Problem with Javascript and opening a new page

Hi,
I'm developping a website with Java Server Faces.
I've a problem with JavaScript.
I have a table, and each row of that table, has a button, to display more information about that specific row. I want to display this information in a new window. For this I want to use JavaScript.
The new window, of course, needs some information of the other window, to show the right data.
The first time I click the 'more-information-button', it works perfectly, but from than on, he keeps showing the same information...
Here is my jsp-page of the first page (the one with the table):

Problem with JavaScript in URL iView

Hi,
I am facing a problem with javascript when i am trying to access my application through URL iView. In the javascript window.top is used to access the frames in the window. But the EP is not recognizing it as valid. what exctly the problem and please suggest me a solution.
Ashok.

Hi,,
thanks for the quick reply. But what i asked was different. I will put it in different way. I have deployed a application in Web Application Server and trying to access it through URL iView. My application is pure J2EE application with html,jsp and JS files. In javascript we used window.top property of the java script which is working fine MS IE. The problem is window.top is a IE specific property which is not having any equallent open standerd so EP is throwing a java script error. As I know the only possible solution for this problem is inherating IE rendaring capabilities to iView(i.e iFrame). is there any way to do that?

JSF problems with Javascript

Hi everyone!!
The situation is this: I have a datable with one of its columns make an h:commanLink, which has two f:params, its actionListener is a function of a ManagedBean. This is JSF, not MyFaces. In IE, When the link is pressed, it shows a javascript error: " 'elements.idVar' is null or it's not an object ", however in Firefox, it works perfectly. I have been looking for the problem and it have to do with this:
</form><a href="# onclick="clearFormHiddenParams_formResultado('formResultado');document.forms['formResultado'['formResultado:_idcl'].value='formResultado:dtTablaResultados:0:_id10';document.forms['formResultado']['idVar'].value='37';document.forms['formResultado']['idMun'].value='168'; document.forms['formResultado'].submit(); return false;"><span id="formResultado:dtTablaResultados:0:itColumna3" title="AREA COSECHADA EN CULTIVOS PERMANENTES">1,230</span></a></td>
</tr>
<tr class="standardTable_Row2">
<td><span id="formResultado:dtTablaResultados:1:itColumna1" style="text-align:center;" title="Código Municipio">718</span></td>
<td><a href="javascript:void(0)" onclick="javascript:window.opener.opener.showLink('SASAIMA')"><span id="formResultado:dtTablaResultados:1:itColumna2_l" title="Municipio">SASAIMA</span></a></td>
<td><form id="formResultado:dtTablaResultados:1:_id9" method="post" action="/ConsultaEstadisticasGeo/resultadoConsulta.jsf" enctype="application/x-www-form-urlencoded">
<input type="hidden" name="com.sun.faces.VIEW" id="com.sun.faces.VIEW" value="_id39:_id41" /><input type="hidden" name="formResultado:dtTablaResultados:1:_id9" value="formResultado:dtTablaResultados:1:_id9" /><input type="hidden" name="idVar" /><input type="hidden" name="idMun" /><input type="hidden" name="formResultado:_idcl" />
<script type="text/javascript">

</script>
the way JSF manage the params. The error, acdording to the message shonw by IE is in this line: curForm.elements['idVar'].value = null;
The code of the JSP is this:
<h:commandLink     actionListener="#{consultaEstadisticasMB.detalleEstadistica}">
     <f:param name="idVar" value="#{consultaEstadisticasMB.idColumna3}" id="idVar" />
     <f:param name="idMun" value="#{registro[0]}" id="idMun" />
     <h:outputText title="#{consultaEstadisticasMB.columna3}" id="itColumna3" value="#{registro[2]}" />
</h:commandLink>
Waht can i do? (Not using MyFaces, because I can�t do that)
Thanks for your answers!!

I have run into this same problem with javascript and the colon. I am not sure if the colon is a valid character for a javascript identifier (one would think the RI developers would have checked it out though!?!).
Anyway, my workaround is to search through the Javascript DOM for the widget you want to obtain a reference to, using part of its id. After all, you know its id, you just can't use it as a javascript reference. In your Javascript code, do something like:
    var inputWidgets = document.getElementsByTagName("input");
    var targetInput;
    for(var i = 0; i < inputWidgets.length; i++)
       var inputId = inputWidgets.id;
if(inputId.indexOf("yourInputId") != -1)
targetInput = inputWidgets[i];
break;
It's a lot of effort to just get a reference to a form widget....but it works (I pasted in the code and changed it a bit, so it might not work as is, but at least it demonstrates the idea).

Problem with JavaBeans in JSP.IT'S URGENT!!!

Hi, i have problems with JavaBeans in JSP.

where ParamBean it's a "bean" class locating in jakarta-tomcat-4.0.6\webapps\examples\web-inf\classes\licentza (licentza is the package i'm using).
And i get this error:

Webcontrol problems with javascript

Hello,
the page I want to navigate making me problems in my webcontrol. The same page works fine if I go there manually with the Internet Explorer. I force webcontrol to use another IE version than default. I changed regedit >
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION
and a new key for my application with value 2af8(11000)
If I do not force this version the used version in the webcontrol seems to be to old.
I think that my application does not use the settings of my IE because if I use IE manually it works.
I used Google and I can not find a property to force the webcontrol to activate javascript - it seems that I have to change this by the "global" settings.
Edit: I do not exactly know if its javascript. The error is a script error.
It does not help to suppress this errors - the page is not working correctly

Hello,
in the meantime I tried GeckoFX to solve the issue, but I get another problem later so I come back to the native webcontrol. To get help I will translate the error message because I can not attach a screenshot
"Scripterror
URL: http://www.transerv2000.de/DesktopModules/SNITNET_Metrix/js/rma_main.js
Do you want to continue? Yes / No"
Because I see the .js I think that this is an issue because of javascript.
If I navigate to this site and do some work I have no problems. This is why I think that the used IE in my webcontrol is having other settings?!
Please help and thanks alot.
Edit: If I supress javascript errors, I got not Messagebox but the content dont work - so I really think that it is a problem with javascript. As I said, if I use the IE as application the page works fine.

Problem with Sessions in JSP

Hi,
I am working on a JSP based website, where I am facing problem with sessions. The user is asked to login by providing her id and password. If found correct, a bean is created and populated with all her details and placed in session scope. I plan to use the information stored in the bean on other related pages until she logs out.
<jsp:useBean id="validUser" scope="session" class="UserBean" >
<c:set target="${validUser}" property="userId" value="${fn:trim(dbValues.UserId)}" />
<c:set target="${validUser}" property="userName" value="${fn:trim(dbValues.UserName)}" />
</jsp:useBean>
<c:redirect url="userHome.jsp" /> The user is presented her homepage - 'userHome.jsp', where she can find various links, like 'Update Profile', 'Pay Registration Fees', 'Book Room' etc. The information stored in the bean is available on 'userHome.jsp'page.
<A HREF='userHome.jsp'>Home</A>
<A HREF='editPersonal.jsp'>Update Profile</A>
<A HREF='registrationFee.jsp'>Pay Registration Fees</A>
<A HREF='bookRoom.jsp'>Book Room</A>
<A HREF='logout.jsp'>Logout</A> The problems are:
1. Whenever user clicks on any of the above mentioned links and moves to any page, the bean comes out as null.
<%-- Verify that the user is logged in --%>
<c:if test="${validUser == null}">
<jsp:forward page="loginForm.jsp">
<jsp:param name="origURL" value="${pageContext.request.requestURL}" />
<jsp:param name="errorMsg" value="You must be logged in to access this site." />
</jsp:forward>
</c:if> 2. The URL shows an additional jsessionid, which my client doesn't want to see.
3. On every click on any link, the value of this jsessionid changes.
What I presume, when I am clicking on different links, my session changes, and so I am seeing a different jsessionid. And since session is changing, therefore the bean is not available in a different session.
All this works fine with localhost, problem comes into picture, when I upload my pages to the server.
Puzzled, can anyone help, where am I going wrong? Let me add here, I am new to JSP and hence don't have much resources with me.

There are several ways sessions can be exchanged between the browser and the server in a j2ee web application.
1. The default is through cookies. However when the client does not accept cookies, the server appends the session id to the url.
2. Some servers also facilitate session information exchange using session id in the url even if the client does accept cookies. This is usually ahieved through a setting in some server configuration file.
You will have to find out why the server in your application is appending the session id to the url.
Whatever be the case, the server should be able to look up the session from the incoming request (be it from the session id in the url or a session cookie).
When session information is exchanged through the JSESSIONID in the url, you should ensure that each and every url that goes to the server has this input parameter. To do that all links and form post urls in your servlet/jsp should be treated with a call to encodeURL().
For example, in a jsp
   <a href = "<%=response.encodeURL("/nextJsp.jsp")%>">Click here </a>
or
   <form action = "<%=response.encodeURL("/nextJsp.jsp")%>">
   </form>etc.

Problem with JavaScript getPageNumWords

Using AR7.0.9. I have a problem with the JavaScript method doc.getPageNumWords and the associated machinery for keeping
track of the words on a page. And I'm wondering if it's a bug,
or something which is not properly defined by the PDF spec.
The situation is illustrated by the test file:
http://www.amrita-cfd.org/4adobe/word-count/test1.pdf
It would appear that the word machinery is aware of
the text in the /Xform's used by /Widget annotations.
But the text is locked in the first time the
machinery is activated on a page i.e. visible /Widget's
are included and invisible ones are ignored.
But since /Widget's can be turned on and off
it's then possible for the word-cache to become out of sync
with respect to the visible text on the page.
Note that a widget which is invisible when
the document is opened, but visible when
doc.getPageNumWords is first called is included
in the word list i.e. the word-cache is computed
once in a just-in-time fashion.
Is the above a known problem, or an inconsistency that has
not been considered before? One solution would be
to add an optional parameter to getPageNumWords
that would force the word-cache to be recomputed,
when needed. Thus removing the need to keep automatic
track of which widgets to include and exclude.

Problem with JavaScript snipet that DreamWeaver is writing

I am having a problem with code that DreamWeaver (CS3) is
writing. I'm fairly certain the problem is in a small piece of
JavaScript that DreamWeaver is composing.
This is a fairly complex problem, so bear with me.
First - What I am trying to make happen: When on a page on my
site (the-oilman.com) I want a link that opens a new window in the
on-line store at a different site (AMSOIL.com). I need to leave
both the page on my site open and have this 'store' page open.
First of all this is working fine, using the 'Open Window'
'behavior' in DreamWeaver. If someone wants to change windows (or
tabs) and go back to my page, leaving the 'store' window open also
- the problem is set up to happen. If from back at my site, you
click on the same or a different link that goes back to the 'store'
either on the same page or a different page at AMSOIL.com - the
'store' window goes to the correct page, but the 'store' window
does NOT come on top. When they click on a link to go back to the
'store' I need the 'store' window to come to the top. If they have
previously put something in the cart, and come back and add
something else to the cart in the 'store' by coming in from
different links on my site the 'store' is working correctly because
I leave it open the whole time.
snipets of code that DreamWeaver is writing for my site
(the-oilman.com):
from the head:
<script>

</script>
code from 2 different links that is using this script:
<a href="
http://www.amsoil.com/redirect.cgi?zo=52257&page=storefront/sso"
target="store" onClick="MM_openBrWindow('#','store','')"
csclick="10D39F40">Buy Now</a>
<a href="
http://www.amsoil.com/redirect.cgi?zo=52257&page=store"
title="AMSOIL Store at AMSOIL.com" target="store"
onClick="MM_openBrWindow('http:www.amsoil.com/redirect.cgi?zo=52257&page=store','stor e','')">On
Line Store</a>
I believe what I need is a longer javascript. Instead of just
"window.open" I need an "if" but my javascript knowledge is very,
very limited.
I need it to first check that if the window named 'store' is
open then 'focus' it, or if it is not open to open the window named
'store'.
Will this fix my problem? If so, please help me write the
lines of code to do it.
If this isn't the solution, what is the problem and the
solution?
A separate question but related: if you look in the two
different links codes, in the function call one of them uses a
'null' page reference and the other repeats the full link reference
from the href= . Both seem to work, but which is the correct or the
preferred syntax. My guess is there are some browsers that this
will give a problem, but which way is preferred.

Create a new page. Try to apply this same behavior to a link
on that new
page. Look at the code. Can you reproduce the problem there?
The code you
show below has oodles of GL stuff in it. Do you need that GL
markup?
What operational sequence did you go through to get this
behavior call?

Problem with javascript/PHP/ oracle 10g smart quotes

I have a problem with my php form that passes the text field to a javascript object. When I copy text from MS Word that includes smart quotes, the form inputs that into the database as ? (upside down) marks. The charset of the DB is WE8MSWIN1252. How do I store these smart quotes as regular quotes? And also if I can do any conversions on the front end (js or php). I tried doing some conversion but to no avail. Any help would be appreciated thank you. “double”

Decide if you want your HTML pages in Windows code page 1252 or Unicode UTF-8. Then, make sure the pages are properly tagged as either "text/html;charset=windows-1252" or "text/html;charset=utf-8". Use HTTP header Content-type or the corresponding <META HTTP-EQUIV=...> tag. Then, set NLS_LANG environment variable for your PHP engine to either AMERICAN_AMERICA.WE8MSWIN1252 or to AMERICAN_AMERICA.AL32UTF8, depending on which encoding you selected for your HTML.

Problem with JavaScript code in Page Attributes, modal popup...

Hello all!
I'm encountering a problem with a modal popup I wrote in JavaScript.
h3.
The situation*
A user sees an interactive report with rows that are clickable, so these rows are links. Upon clicking the name of something in a row, some items get a certain value and a modal popup shows on the screen. In this modal popup, there are details regarding that particular row the user has clicked, but the problem_ here is...
The modal popup closes itself only seconds after it has been opened.
This must be because I've probably made a mistake somewhere in my code, but I just can't figure out where... It also appears that when I click on a row link, the popup shows, but the progress bar of my toolbar seems to show a loading bar (as if I refreshed the page).
h3.
My code*
This code is located in the _"Function and Global Variable Declaration"_ part, under the _"JavaScript"_ tab. Code is in the _"Page Attributes"_ of my page 24.

Link Text: #FOODTEMPLATENAME#
Link Attributes: class="temppop"
Target: Page in this Application
Page: 24
Item 1, name: P24_MEALID; item 1, value: #MEALTYPEID#
Item 2, name: P24_TEMPLATEID; item 2, value: #FOODTEMPLATEID#So basically I call the function to open the modal popup by the class name. When a link with that class name in it is clicked, it opens the popup.
To remind you of the problem, the modal popup closes seconds after it has been opened. How do I fix this?
Thanks in advance.

Problem with JavaScript in DPS

Hello,
i have little problem with one HTML page in DPS. We've created HTML form, which is formatting output with JavaScript and then passing to local mail client via mailto. It works nicely in Safari on desktop, it works in Safari on iPad BUT it don't work in DPS, when we use it as HTML content (frame on page where form is loaded). Unfortunately, there is no way how to learn what's wrong - on iPad it works, it's not working just in DPS (and it's not working in Viewer on desktop too).
Anyone have any idea what to do?
Script is fairly simple, it's my compilation of other works, because i'm not JS programmer, just i'm skilled with google-copy-paste... So there can be some VERY trivial error, but i don't know correct syntax...
very simple version of this form, which is not working in DPS (but everywhere else), is here
http://dl.optio.cz/mailtoExample.html
Thanks for any help!

Hello,
when used in DPS browser, it's working (as part of HTMLresources.zip). I don't know if this will help, but here is small game, which works correctly in DPS in web overlay. when you move any red circle, it will let you send results via email. But this is too complicated for my minimal skills.

Anyway, thanks for help

Problem with javascript confirm() in a JSP

I'm trying to use a confirm() box in a jsp. I've looked at tons of examples and I still have the same problem. If I just add this to my page the prompt will pop up as expected: (of course it doesn't really do anything.)<SCRIPT LANGUAGE="JavaScript">
confirm( "Are you sure you want to delete?" )
</SCRIPT>As soon as I add an if clause around it it doesn't even pop up anymore, such as:if (confirm("Are you sure you want to delete?")){
<%
     Do some jsp stuff
%>
else {
<%
     Do some jsp stuff
%>
}I can include more of the code if needed. This code is for deleting some files, so I want to add an "are you sure prompt?". If they hit ok it will delete, otherwise cancel the operation.
I assume that the "if confirm( "Are you sure you want to delete?" ) " should wait for a reponse before continuing. Any help is appreciated.
Thanks,
James

You can use Javascript to confirm a delete, and delete an object in the following manner.
//link to delete an object..
<a href="thisPage.jsp?delete=<%= itemID %>"
   onClick="return confirm('Are you sure you wish to delete this item?');">delete</a>Then, at the top of the JSP pageif(request.getParameter("delete") != null)
   //do whatever to delete, then load the page as normal
}Now, your item will be deleted, and the page will be refreshed to show the changes.

Problem with onload in jsp page

Hi all,
I had two jsp pages, a search and a results page. I need to enter some search criteria in the first page and based on that criteria i will be getting the results in the results jsp. Now, when i click the back button in the results page, i need to go to the search page and the values which i entered in the search page needs to be present there. But the problem is i had a javascript function which runs on loading of the search page. This function will set all the values in this search page to empty whenever we go to the search page. I am calling this javascript function as follows in my search jsp page.
<body onload="setdefaultvalues('<%=name%>');">
I am having the code for the back button in the results page as follows.
<INPUT TYPE="button" VALUE='Back' onClick="javascript:history.go(-1);resetvalue(name);" class="button">
The problem i am facing is whenever i go to the search page by clicking on the back button, the values in the search page are getting empty because of the onload method. There is no way that i can remove this onload method as i require it for setting the values in the search page evrytime i get to that from other modules as it is the main page for my module. So, is there anyway that i can stop this function from executing when i come from the results page or is there any other way that i can store the values in the search page when going from the results page.

i think you really should have the result page include your search page contents rather than having the user need to click back as you'll end up with all sorts of nightmares in caching & session object management to be honest. if the search page is complex use javascript to hide contents and let the users expand them when they want to re-search.
however, if you feel you must i would suggest the following:
in your result page:
session.setAttribute("userQuery","true"); (you probably actually want to put a container object with the query information in here)
in your search page you could have something like:
<body <% session.getAttribute("userQuery")==null { %>onload="setdefaultvalues('<%=name%>');"<% } %>>
-or-
<body onload="setdefaultvalues('<%=name%>',<%=session.getAttribute("userQuery")==null?"true":"false"%>);">
function setdefaultvalues(name,run) { if ( !run ) return;....}
you'll have to decide when to remove the object though cause once its set its there until the session expires or you remove it.
hope that helps, good luck!
