Can we call a javascript fun through jsp page without any event

Hi ,
I am new to jsp,javascript and i have a little question.
If i make a function in a js file and want to call it from a jsp file without any event ,ie can i write some thing like <%abc()%> in ths jsp page ,which call the function from another .js file.
I suppose that it can be done as gmail page reloads it self after some time and for http mostly we use pull ie request from the client side ,so i think that they must be doing something like timer expiry and reload themselves.
please help me with the solution.
Thanks & Regards
Saurabh

sorta....
The JS runs in the client, not on the server, so you would just be writing JS code as HTML... If your page is like this and the myscript.js file defines 2 functions (function1, function2), you can call them on page load in either of these ways. I'm not sure offhand which would get called first, but the scripts called inline in the page would be called in the order they are defined in the page. But that is all HTML, it has nothing to do with JSP.
<head>
<script language="JavaScript" type="text/javascript" src="myscript.js" />
</head>
<body onload="function1();">
<script language="JavaScript" type="text/javascript">
function2();
</script>
</body>

How can i call java class file in jsp page

Hai,
i wants to call .class file in jsp page.
my class file is in C:\jsdk\bin.
Thanks

I'm not entirely sure what you mean by "calling a class file", but I'm going to assume that you want to do something like the following in your page:
<%
MyClass myClass = new MyClass();
myClass.someMethod();
%>etc
If that's the case, then all you have to do is make sure that the class is in the servlet engine's classpath. You'll probably also need to include an appropriate import statement at the top of the page.
Hope that helps.

How can I access xml document from javascript whithin a JSP page

how can I access xml document from javascript whithin a JSP page?
I have a JSP that receives an XML document from a JavaBean, so I can access it within the entire JSP, but I need to access it from the javascript inside the JSP... and I have no idea how i can do this.
Thanks in advance!

The solution would only work on MS IE browsers, as other browsers do not support an XML DOM.
It can be done, but you would be stuck with using the Microsoft broswer. If that is acceptable, I have some example code, and a book recommendation.

How can we use java variable in javascript code on JSP page?

How can we use java variable in javascript code on JSP page?
Pls help

Think about it:
JSP/Java is executed on the Server and produces HTML+JavaScript.
Then that HTML+JavaScript is transfered to the client. The client now interpretes the HTML+JavaScript.
Obviously there's no way to access a Java variable directly from JavaScript.
What you can do, however, is write out some JavaScript that creates a JavaScript variable containing the value of your Java variable.

Including JavaScript into a JSP Page

Hi,
How do i include a piece of JavaScript <SCRIPT> stuff into a JSP Page?
Right now i have an HTML Page that includes some <SCRIPT> code. Now many other HTML files use this piece of <SCRIPT> stuff. How do i remove it , put it in one place(I mean where to put it and what would that file be called) and in a JSP page call this <SCRIPT> code?
Please help . i'm pretty new to JSP and JavaScript.
Thanks in Advance.

/**** CODE
<SCRIPT language=javascript>

</SCRIPT>

Ok, first let us make clear the demarcation between java and javascript.
Java runs on the server, and produces an HTML page which is sent to the client.
That HTML page may contain javascript code on it to run on the client side.
As the page is loaded, javascript may be compiled/run on the client.
So you have some javascript code which you want to include on every page as template text?
I would do this in JSP by using the include directive to add that bit of template text to every single JSP page.
ie
header.jspf
<SCRIPT language=javascript>

</SCRIPT>
<noscript>
// stuff here for when the browser does not support javascript
</noscript>And then in every jsp page
<%@ page include="header.jspf" %>
// rest of the JSP pageThe file "header.jspf" will be included with every jsp page served, and you only need to update that page in one place.
If you have a JSP2.0 container you can define a jsp prelude which will be the same as having the <%@ page include="header.jspf" %> on every page.
You do this in the web.xml file:
Something like this:
<jsp-property-group>
     <url-pattern>*.jsp</url-pattern>
     <include-prelude>/WEB-INF/jspf/prelude1.jspf</include-prelude>
</jsp-property-group>The specified file will be loaded into every JSP page without the JSP page having to define the import itself.
Hope this helps,

Virus scan failed Error on deploying a web application having a jar file for calling the applet on the jsp page

Hi,
I have an applet application that i want to deploy on the Oracle cloud.
So i have created a jar file for the applet application and i am using this jar to call the applet on a jsp page.
But when i am delpoying my application on the java cloud, its giving me the below error:
2014-10-28 03:16:41 CDT: Starting action "Virus Scan"

Can't we deploy any application having applet or swing component's onto the cloud?
Or do we need to request for any extra permissions for the same?
Thanks,
Manoj

I don't see applets mentioned in the supported features nor in the unsupported features so not sure if they are supported you would likely need to contact the operations team to confirm.

How to call a report from a jsp page

Hi
1) Can anyone please tell me how can i view Discoverer report from a jsp page instead of opening it directly thru plus/viewer.
2) Please clarify do i need to install Infrastructure and OID for it.
Please advice.
Thanks

You need the AS infrastructure if you want to use connections. If you do not intend using connections, you do not require the infrastructure.
Note that you cannot pass in passwords in the URL any longer. You do not need to pass passwords if you pass in a Discoverer connection id (but then again - if you don't use connections, then you do need to still pass in the connection information - username, password, database, language, EUL)
I have a post on my blog that describes how to pass a password using an HTML Form submit - http://oraclebi.blogspot.com/2005/08/passing-password-to-viewer.html

Hi Friend,
These are the codings to be wirtten in BSP for transferring values to the REPORT
DATA:wf_date TYPE ztable-ID.
      data:seltab type standard table of rsparams,
       wa_seltab like line of seltab,
     event TYPE REF TO if_htmlb_data.
DATA:p_value TYPE REF TO CL_HTMLB_INPUTFIELD.
event = cl_htmlb_manager=>get_event( runtime->server->request ).
p_requ ?= CL_HTMLB_MANAGER=>GET_DATA(
                                        request = runtime->server->request
                                        name     = 'inputField'
                                        id       = 'i1'
if p_requ is not initial.
wf_date = p_requ->value.
endif.
clear wa_seltab.
if wf_date is not initial.
wa_seltab-selname = 'P_REQU'.
wa_seltab-kind = 'P'.
wa_seltab-option = 'EQ'.
wa_seltab-low = wf_date.
append wa_seltab to seltab.
endif.
submit *ZSAMPLEAP1* with selection-table seltab AND RETURN .(ZSAMPLEAP1 refers to the report name and AND RETURN for coming back to the BSP page after the completion of its operation in Report )
IMPORT int_name TO int_name FROM MEMORY ID '*zid*'.(For importing the obtained value from Report)
In Report
REPORT ZSAMPLEAP1.
SELECT-OPTIONS: p_requ FOR ztable-id NO INTERVALS.
SELECT SINGLE name from ztable into int_name WHERE id = p_requ-low.
WRITE:int_name.
    EXPORT int_name TO MEMORY ID 'zsharmila'.

hi,
I wanted to use the JTabbedPane for tab buttons in my

As for GUI (graphics) in the HTML page you can use only the html form elements (but you should simulate other behaviours by dynamically reloading the page).-

Forward to JSP page without using Navigation Model

How can I forward to a JSP page without using the Navigation Model?

It's done in the cardemo example in
ImageMapEventHandler.processAction() Is there a reason
for it there?Ah ... that makes sense.
That code in CarDemo was written before there was such a thing as a NavigationHandler, and we didn't have time to update it to the new approach before the EA4 release. That'll be changed before the next one. In the mean time, I'd recommend that you use the navigation rules mechanism where it works for you, because it encourages good separation of business logic and presentation logic that will lead to more maintainable applications.

Whatever you read was incorrect. You can upgrade directly to Mavericks. It is in the App Store and is free.
Snow Leopard predates the operating system you already have. That's the reason it will not install on your MacBook Air. You spent $20 needlessly for it, but it's yours to resell if you wish.

I don't think you're on iOS 5, I think you're using iOS 6. That's the latest version.
Unless you've used iCloud to back up your documents, you won't be able to restore them. And for future reference, you don't have to uninstall Pages to update your iPad anymore. Sorry about this.
