Parameters b/w javascript and JSp

how i can pass values between javascript and jsp .
( java script varaible in the JSP part & jsp object in the javascript code )

Since Java script is on the client side , to get the value of a java script variable into jsp, u have to set some form field variable and submit it to the server again. So, it can be something like:
<script>
function submit()
     var scriptVar = 12;
     document.form1.formVariable.value=scriptVar;
     document.form1.submit();
</script>
<%
System.out.println("Script variable value = " +request.getParameter("formVariable"));
%>
<form name="form1" method="post">
<input type="hidden" name="formVariable" value=""/>
<input type="button" name="bSubmit" value="Submit" onclick="javascript:submit()" />
</form>
The first time this jsp is called, the value of formVariable will be null.
The next time, when u click on submit button, the value will be 12.
I have not tested this. There might be some syntax errors. Just try it out. Also, make sure that u don't end up submitting the form in an infinite loop by using the submit() generally in the script. Hope this helps.

Mix JavaScript and JSP

Hi.
I have jsp and javascript mixed when I click a check call a function javascript for example:
//JavaScript
function Hola(numerop) {
idRol = Number(numerop)
<%nombreRol = roles.get(numerop)%> }
//Form
<input type="checkbox" name="<%=roles.get(sum)%>" value="<%=roles.get(sum)%>" onClick="Hola('<%=roles.get(sum)%>')">
In the function numerop is a number but in the jsp code numerop is undefined.
How I can mixed javaScript and jsp??
Please I need help you.

Remember that the JSP runs on the server and generates the HTML, including Javascript. The Javascript runs on the browser after the JSP is finished. So you cannot do whatever it is you expected that to do.

Problem in JavaScript and JSP

Hello all, I have a problem. I am using a file upload box in my JSP page.
And I want to put some validations on the input of that file - see if it exists, check its size, or may be its type. I tried to use ActiveXObject in the JavaScript but it gives an error - ActiveXObject is not defined. Is not allowed to use ActiveX object in JavaScript. if not then where can we use such an object. I used such a FileSystemObject in VbScript, but that too was a independent running scripts like .vbs file. Can anybody help?

Use of ActiveX object is strongly discouraged, however
Check if this solution solves your problem
Inorder to use ActiveX Objects ,check whether ActiveX object s are enabled in IE.
Goto IE>Internet Options>Security Tab>click button Custom level>
scroll to 'Run ActiveX controls and plug-ins'>select �enable�.
also enable "Initialize and script ActiveX control not marked as safe."

Again combining javascript and jsp

can i do the post methode of a form inner a javascript function?
i want first check whether the reqiered fileds r filled and the do the post action.
Andre

Yeah that is really quite simple....
function FormValidation()
//do Validation stuff here
document.MyForm.submit;
<HTML><BODY>
<input type=submit name=submit value="Submit
onclick = "FormValidation(); return false;">
The return false will cancel the submit action.
null

Javascript and jsp forms

Hi,
I have the following java code what I am trying to do is to use some java script to read values from the buttons. As per my thinking the javascript code when called should print out the no of radio buttons but what it is giving is undefined. Could somebody point out what I ma doing wrong???????
Its already drawing me crazy.
<dsp:form name="students" action="../../check.jsp" method="post">
            <P>books </P>
      <INPUT type="radio" name="books" value="Java2InANutShell">
                               Java 2 in a nutshell
                      </INPUT>
                      <br><br>
     <input type="button" value="Length" id="length"      name="Log In" onclick="launchAutoWindow()"/>
</dsp:form>
function launchAutoWindow(id)
alert(document.students.books.length);
}

You only have one radio with the name of "books" on
the page.
If you have only one, "document.students.books"
evaluates directly to the radio object
If there is more than one object with that name, it
evaluates to an array of the objects. At that point,
length would be defined.
So if length is not defined, you know you only have
one :-)
Don't you just love javascript?Thanx mate. That solved the problem. I would have never figured it out myself. Thats kindaa silly but as long as it works ;)
Thanx again.

Embed javascript in JSP

hi
i want to store the query string of an URL in a flat file. but i want to append the name of the person who's passing the query string by prompting him to enter his/her name. i have a code something like this
FileWriter outputFile = new FileWriter("Libset1.txt", true);
BufferedWriter outputBuffer= new BufferedWriter(outputFile);
final PrintWriter outputWriter = new PrintWriter(outputBuffer);
//writes all data to the output file
for (int i=0; i<Selected_set1.length; i++)
outputWriter.println("some javascript to prompt the user goes here..." + Selected_set1);
outputWriter.close(); //closes output file
i want to embed some javascript in place "some javascript to prompt the user goes here..." prompting the user to enter his name..
is it possible to do that. if yes, how.?
sorry i'm just a beginner, it might look silly for you...please help...
thanks in advance..

First of all, you need to understand how Javascript and JSP work together....they don't. Javascript is a client side scripting language, which means that it executes and runs in the client browser after the page has been loaded. JSP is purely server side, it only runs while the request is being serviced, or while it's generating the HTML to send back to the client browser.
To do what you're asking for should be pretty easy using javascript. You should be able to use the Javascript onClick() event for the link the user is clicking on to execute a Javascript method that prompts the user for their name.
You might try something like this...
<script language="JavaScript">
function promptUser(newPage)
var username = prompt("Please enter your username");
if(username)
document.location = newPage + "&username=" + username;
}</script>
Click Here Please!
This will result in a query string that looks something like mypage.jsp?id=23&view=whatever&username=john
Make sense?

Problem with include and relative path in jsp

Precompile jsp with wlappc in 9.2, I got the error "The include file was not found" when the jsp use <%@ include file="../includes/dataEntry/code_error.html" %>
          This code used to work with 8.1. I notice that someone has report the same problem with 9.0 and you have patch for it. Is it fix in 9.2 or do I require a patch as well?
          Thanks,
          Khuemy

When you precompile, can you say "Keepgenerated=TRUE". It might help you track
          down the difference with the URL. You should only get a 404 error when the
          resource is not found at runtime, which is independant of when you compile. The
          difference should be in how the URL is compiled.

WL vs. WL-express and JSP vs. javascript/SQL

folks-
i am trying to convince a certain party to
disband a web-based job tracking system being
written in ASP, javascript, html, css and SQL.
it will be hosted on MS webserver running NT.
i am trying to convince them to use JSP and
WL express. i have done two years of EJB
component work on weblogic, however, i have not
done work with JSP or thin-clients. i was mostly
business-logic.
anyway i have some questions and need some
direction. i already know JSP is better than
ASP/javascript etc. because:
* ASP is proprietary. ditto for VBscript
* with an IDE creating JSP is easy and JSP
automatically creates servlets which is way
faster than by hand
* JSP is JAVA based and hence benefits from
all the portability pluses of JAVA
but here are the more difficult questions:
* why is WL express better than an MS
web server? (not including WL market share
and size. after all MS can claim that)
* since WL express does not have an EJB
container, how do you access the database?
via JDBC? does one just have JDBC code
floating around?
* since there is no EJB container how does
one separate presentation from logic from
data access? this is a major downside of
javascript, html, css and SQL etc.
* if a web app grows beyond JSP with WL express
into the need for an EJB container, i would
think that most of the app needs to re-written
as business-logic must be refactored into EJBs
and all JDBC code will be replaced by container
managed beans. this sounds a like a lot of
rework.
* isn't JSP slower than javascript as the
servlet and hmtl code is bounced back and
force across the network?
with respect to architecture, scalability,
and robustness what are the downsides to an
MS webserver and non-JSP coding?

* since WL express does not have an EJB
container, how do you access the database?

Use JDO or an OR-mapper or embed JDBC into your own data access classes.
* since there is no EJB container how does
one separate presentation from logic from
data access? this is a major downside of
javascript, html, css and SQL etc.
Presentation=JSP
Logic=Servlet
Data access=JDO or similar

You should be able to tell up front if it a tx-intensive app that requires
WLS.
* isn't JSP slower than javascript as the
servlet and hmtl code is bounced back and

They aren't exclusive. For dynamic pages, use Javascript on the front end,
JSP on the back.
* with respect to architecture, scalability,
and robustness what are the downsides to an
MS webserver and non-JSP coding?
In the real world, and for most apps, while Java has the architectural edge,
they both have similar scalability and similar robustness. MS gives you no
choice though, and you rewrite every time they see a new buzzword. You can't
leave MS-land without abandoning almost everything. You can leave WLS in a
week if you have to.
It's an investment. Invest wisely.

EXPRESS and JSP relation

have got some basic doubtd in IDM
We have XML and JSPs how both r getting related in
the sense Take Login Form --> Login.jsp how both
are gettign related
Suppose In form1 I am entering some data that data
if I want to recieve in form 2 How to specify the
action ?
It seems elementary
Thanks in Advance
senthilRajan

I'm not really sure I understand your question.
Although it's probably generally true that a JSP file maps to an XML form, it's not always the case.
Can you be more specific about what you are trying to do? Are form1 and form2 different forms that would be presented during the processing of a workflow? Are you referring to end user vs. and admin activity?
Often it can be easier to use a single form that nests fields within fields that can be conditionally disabled. Thus, a single form can look like multiple different forms. Or you can use tabs in the form spread fields out on multiple tabbed pages.
Hope that helps,

FORM and JSP in the same page

Hello All
Is it possible to pass variable from a html textbox to a JSP? but they both are in the same page.
For this purpose, I have a created a index.html, which contain two frames, top.html and bottom.jsp. There is a textbox in the top.html, it collects 2 variables and use form action "POST" to call bottom.jsp to display a graph.
However after I run this page on Tomcat, it gave me error message in the bottom.html:
The server encountered an internal error () that prevented it from fulfilling this request.
Can anyone teach me how to solve this problem? Thanks a lot
Viola
index.html
===============================
(FRAME) top.html
<form action="bottom.jsp" method="post">
<input type="text" name="apple">
<input type="text" name="orange">
===============================
(FRAME) bottom.jsp
String apple = request.getParameter("apple");
String orange = request.getParameter("orange");
use those two variables to do something
and display a graph

The problem is that both pages are loaded @ the same time so when the getParameter gets executed the parameters are null and this is the probable cause of your error. Another problem is the action in form will cause the bottom to go into tops frame and not have anything to do with the other frame. If you want data to go from one frame to another while the user still sees them look @ DHTML, JavaScript and IFrames.

How to find out the filename of javascript and pathname of javascript?

I got the filename of javascript and pathname of javascript(not the active document file name) using the below code in illustrator cs3.
var path = $.fileName;
But my problem was if i run the javascript through "extendscript toolkit" i got it correctly. But if i run my script through illustrator cs3 application(File->Scripts->test.jsx) i got some integer value only(did not get the javascript filepath and filename). Kindly advice how to get the javascript file name and file path in windows platform through illustrator cs3 javascript. Please help me.

I already have that extension, but I'm not sure which idx I need to look at. Also, I suppose that the numbers I'm looking for depend on places.history.expiration.transient_current_max_pages and therefore there is no way to get them relative to the installation of Firefox. My point is, I can see my history only up to 1 year, even though I have Firefox installed for 3 years. Correct me if I'm wrong.

Associating two events with submit button using javascript in jsp

Hi
How can i Associate two events with submit button using javascript in jsp. Firstly it should insert the data to database and secondly it should close the same pop-up window

Have something like :
<input type="submit" name="submitbtn" value="Click me" onClick="function1(); function2(); " />
You just call both functions sequentially, it's that simple. Although using javascript to work with a database, that seems a bit tricky.

Help me!! How to use JavaScript with JSP ??

I am using JDeveloper and I created a screen in JSP which uses a bean for database connectivity and retriving info onto the page.
The page has a ListBox where list items are populated from the database.My requirement is
whenever the list is changed the page shuold be refreshed with the selected item info.
I tried to use 'JavaScript' for triggering the event with 'onChange' event of the ListBox.But the event is not getting invoked. I think JavaScript is not working with JSP.
Please help me with how to Use javaScript with JSP or any other alternative where I can meet my requirement.
I have one more question...I have gone through the JSP samples in OTN and I am trying do download the sample 'Travel servlet' which show list of countries...etc
I have also gone through the 'readme' but I don't know how to extract .jar file.
I would be great if you could help me in this.
Thanks!!

We have a similar need. We have used Cold Fusion to display data from Our Oracle Database. We have a simple SElect Box in HTML populated with the oracle data. When someone selects say the State of Pennsylvania. then we have an On change event that runs a Javascript to go get all the cities in Pennsylvania.
Proble we are having is that inorder for the Javascript to work , we currently have to send all the valid data.
Do you know of any way to dynamically query the the Oracle database in Javascript
