Alert srceen in JSP

Hi,
New to JSP, do we have a function to pop up an alert message in JSP?
Thanks.
Jason

This was just an example. Did you expect me to write all of the code he wants? Just trying to show what it would like. JSP is a page. It can include beans, Javascript and of course HTML tags. So it is amateur to say that it is not JSP and it is javascript. Even if you built your page with .java file you must write: <HEAD> and <BODY> and the rest tags. That doesnt me that your page is not JSP!

Using window.alert in a jsp file

I am creating a website, when a user is found invalid I want to display an alert. The code is below
    if( invalid )
         window.alert( "Invalide user" );
         response.sendRedirect( "login.jsp" );
   } The problem is that window.alert is not working, Please tell how to solve this problem.
Thanks

You need to distinguish between the serverside Java programming language and the clientside Javascript scripting language. Those are two completely different languages. The alert() is a Javascript function, not a Java class/method.

Polish , turkish text not decoding in the alert boxes in JSP file

Hi All,
Currently I am working on application in the J2ee development perspective in NWDI and this contains many Jsp pages.As per the business requirement we need to make this application support Polish and turkish languages , for this we have maintained properties files .
I have encoded the polish and turkish text using the u201CHTML Unicode format encodingu201D hence when checked the url in the IE with Polish and turkish locale all the characters are getting decoded properly ,but i have a proplem with the text in the alert boxes i.e. the special characters in the text displayed in the alert boxes is not getting decoded at all eg:"Wprowadź numer konta BP" whereas it has to display as "Wprowadź numer konta BP:
Also i have used java encode also to achieve the same and for this "?" is getting displayed i.e. it is not getting properly decoded.
I have also used native2ascii method in this also it is getting decoded but not correctly i.e. "?" is displayed
Please note that the alert boxes are written in the script tag in the JSP page.
Request you to kindly help me in resolving the issue at the earliest as this is a very critical issue in my project now.
Thanks and Regards,
Nishita Salver

Hi nishita,
We had a similar problem in one of my projects, but what i remember is we have kept the ascii value for that character directly in the properties files and tried to encode it, this way i resolved my problem.
Try this way and let me know the result.

The transfer of values works fine when we select one or more values by individually selecting them. But this fails to work when we do a move all or we click on the Select radio button which eventually does a move all.
After analyzing we found that when we do a move all then the form bean does not get updated with the changes made by the user; like suppose we move all from the Select list to Available list then the availableTypes array (which is associated with the Select for Available Types) show all the types moved to it which is correct but the selectedTypes array (which is associated with the Select for Select Types) also shows all the types in the form bean so when the JSP is reloaded then both the lists boxes show the same entries (all the entries on either side), thus duplicating each entry and causing an error.
The same work absolutely correctly when we manually select one or more entries from either of the list boxes. Meaning both the form bean arrays reflect what the user has selected on the screen.
The methods called on click of the buttons are clearly setting and removing entries selected from the two arrays. We put alerts in the JSP to see the changes in the arrays and they reflect correct values. But once the control has been transferred to the java classes we view the form bean values of the same two arrays which show different values.
Please let me know how I can make the changes of the user reflect in the form bean somehow!

'session' is undefined - javascript error in my JSF/JSP page

I have the following JSF/JSP page. In onLoad() I invoke a javascript function func(). In this method, I attempt to lookup an attribute from the Http Session. When I run my application, my page is loaded with but the icon on the lower left corner of the browser indicated that there was an error. When I viewed the error, it read : 'session' is undefined.
The 'session' variable is available in a JSP page.
So why does my code not work from within a JSF application.

Because :

Alert box on form load

can anyone plz tell me how can i display an alert box on jsp page load

Standard way is for the form to have an onload event on the body that invokes some javascript.
<body onload="alert('Hello World')">Or more likely
<script language="javascript">
function loadFormEvent(){
var message = "<%= messageToOutput %>";
alert(message);
</script>
<body onload="loadFormEvent()">Thats a very basic/broken example that won't work in all cases, but should communicate the basics.

Hi Brian,
OAF supports the master-detail based design. You can very well implement your model. You can use 2 VO for your 2 objects and link them using a ViewLink. Check OAF Dev guide for more details.

PS: MAYSCRIPT (imho) is for the reverse - accessing javascript from java With IE6.0/NN7.02 and JRE1.4.2beta, I've found that html file no longer needs to be converted with htmlconverter. Furthermore:
1) a simple <APPLET>...</APPLET> tag is all that is needed (i.e., no longer is there a need for <OBJECT>...</OBJECT> for IE, or <EMBED>...</EMBED> for NN).
2) MAYSCRIPT="true" is all that's needed for Java<-->JavaScript communications via LiveConnect.

How to Show the Alerts inside the Form in JSP?

Hello
I am having parent form inside that thru one of the links,opening
a small another JSP. Inside the small another JSP, i am validating
the Screen and giving alerts. While Validating, the Alerts are coming
outside the small another JSP and appearing in the Parent Big Page.
I want the alert to appear in the small Another JSP. What to do?
Thanks

When you submit, the whole form is submitted. thats why you are getting alerts like that.
you can use HTML frames to avoid these. but it is not possible to have frames inside a form. you have to have forms inside a frame. submit that particular frame's form so that only that part will be refreshed with messages/alerts.
the otherway is paint the screen as it was earlier just change the inner jsp content. its seems you are getting only alerts cos the information is same.

Could not display Alert component in Visualweb JSP page

Hi All,
I am having difficulty getting the Ajax Autovalidation Alert Component to work in Netbeans Visualweb 6.5 on Windows XP with the following steps:
( i ) Set autoValidate attribute of firstnametextField and lastnametextField to "true" from property windows of Page1.jsp.

            </webuijsf:html>
        </webuijsf:page>
    </f:view>
</jsp:root>However, the Alert Component does not pop up after leaving First Name or Last Name text field blank prior to entering the field such as middlenametextField...
Your suggestion would appreciated.
Thanks,
