How can share data between jsp pages using beans??

any one can give me code for 2 jsp pages with bean that share data for them

<jsp:usebean name="yourBeanName" type="com.whatever.foo" scope="session"/>
this will look for a bean named yourBeanName in the scope specified by the scope attribute. If none was found, the container will instantiate one with the no arg constructor for your bean and place it into the proper scope.
if your bean had a method getName(), you could then on your jsp do:
<%=yourBeanName.getName()%> to print the results of the method to the page. there are other ways to do the actual placing of the output on the page, but this is the most direct.

How to share data between applications.

I'm trying to share data between LabVIEW v6.0 and another program (16 bit), both running on Windows95. At first DLL's seemed to be the answer but I would need to call 16 bit DLL's which I understand can be a problem. With my limited knowledge of C++ I've written a program (Borland C++4.2) which can access the data I need and save it to a file, this is then repeatedly read by LabVIEW, crude but it works. When I add code to do the same the other way I get occasional file sharing errors. I can't get either LabVIEW or C++ to trap these errors. As an alternative I thought I could write and read to a reserved portion of memory (less than 1K should be enough) using in port and out port. Is this viable, and if so how do I
reserve the memory in Windows 95 so that LabVIEW & my C++ program can access it?
Any suggestions?

May be TCP/IP or UDP interprocess communication will do? It shouldn't be
a problem via localhost. You can try separate VI server to handle
communication task from your vi with C++ socket.

How the hell does a person share session data between JSP page and a Servle

1. How the hell does one share session data between a servlet and a JSP page without using a bean but rather using a normal string variable.
2. When using session scope to access a bean the application complains about not finding the bean on the specified scope, however when I use an application scope the save the same bean, the application does find it.
Please help!!!!!!!
SERVLET:
HttpSession session = request.getSession(true);
ServletContext servletContext = session.getServletContext();
customerID = result.getString("CustomerID");
userName = result.getString("UserName");
session.setAttribute("UserName",userName);
session.setAttribute("CustomerID",customerID);
System.out.println("Customer UserName = " + session.getAttribute("UserName"));
response.sendRedirect("/economics/subscriptions/default.jsp");
JSP PAGE:
<?xml version="1.0" encoding="UTF-8"?>
<jsp:root xmlns:jsp=http://java.sun.com/JSP/Page mlns:c="http://java.sun.com/jsp/jstl/core" xmlns:sql="http://java.sun.com/jsp/jstl/sql" version="2.0">
<jsp:directive.page isThreadSafe="true" session="true" contentType="text/xml"/><jsp:output omit-xml-declaration="false"/><jsp:scriptlet>response.addHeader("x-xslt-nocache", "true");</jsp:scriptlet><pml>
<page type="web" search="y">
     <pageName>Commercial Banking</pageName>
     <jsp:directive.include file="/economics/header.inc"/>
     <jsp:directive.include file="/login.inc"/>
     <jsp:directive.include file="/economics/leftMenu.inc"/>
     
     <content>
     <searchSum>Commercial - Main Content</searchSum>
     Value = <c:out value="${request.session.getAttribute("UserName")}"/>
     </content>
     <jsp:directive.include file="/economics/rightNav.inc"/>
     <jsp:directive.include file="/footer.inc"/>
</page></pml></jsp:root>

For a start, just "session" instead of "request.session" would work better. But why did you post this here and not in the JSP forum? Doesn't seem to have anything to do with Java programming.

How can I change between JSP and Java in the page language attribute

Does any one know the answer to this? I am trying to Switch between the 2 in the middle of the page. I want to include a file that uses <%@ page language = "JAVA" %> but the main mage uses Java Script. How can I switch it for this one file. I can't find the answer anywhere. Thanks for your time, and please help me. Also can some one post a good link for Session Tracking. I can't find much good information on that. Thanks again.

Wow this didn't make sense in so many ways. It's truly bordering on nonsense. I think it's written in English.
<%@ page language="Java" %>This is optional. JSPs don't use any language other than Java. This is known as a JSP Directive. This line will be processed by the JSP/Servlet engine, and you won't see it in your output. If JSP ever supported a language other than Java, this would be where you would change it.
<script type="text/javascript">

</script>You can include a block like this in your JSP file. The JSP/Servlet engine will not process this script block at all (unless you include JSP <% %> tags somewhere in there, in which case they will be processed before the response is sent back to the web browser). This script block is where JavaScript goes. This code will be executed on the client's browser.
This is about as clear as I can make things given how muddled your question is. Please ensure you understand the basic differences between JSP, Java, JavaScript, HTML, Servlet engine, web browser before proceeding. Understand what code executes where, and in what order.

Using events (?) to share data between tab pages

I don't know whether this is an event question or an Object-Oriented design question or a JTabbedPane question.
I'm pretty new to Java, so be patient!
I wish to have a JTabbedPane with a tab to do 'Import' of data, and a tab to do 'Export' of data (the SAME data which was imported). Now, how do I share the data between the 2 tabs?
It seems the data belongs at the JFrame level, but then how does the data in each tab access it? In other languages I would pass a reference to the data object in the window to each tab.
Or how do I get (or set) the data when the tab changes? And how do I know when the tab changes?
I think I need to set trigger some sort of event to the parent window, who I suppose has a listener, and then it can then query the appropriate pane? If so, I'm not sure what sort of event trigger I should be using, where etc.
I know if I had one tab with an import/export functionality then I could declare the Collection within that panel.
Help!!!
Thanks ;)

I think this is an OO design question.
You basically have two views (the two panes) of the same data. So I'd suggest the Observer pattern (see the Design Patterns book) where one model holds the data and the model is observed by several views.

How can I make the jsp pages not displayed by using the navigation class?

I'm right now implementing a function on my program GUI . It's like whenever I click "STOP THE SERVER" button on the main page, I need those jsp pages relates to the server running to be not displayed, even by directly type in the URL(that's just stay in the main page), How can I do that? I heard that a navigation class might do it, but I'm not sure how. It might be great if some experts could help me!! Thanx a million !!

How to transfer data between spreadsheets without using Business Objects?

Hello, every time I try and log onto the business objects platform I keep getting "this system can be contacted but there is no central management server running at port 6400". All I need to do is pass variables between spreadsheets. Both files are located in the same folder. Below are the links ive tried but have been unsuccessful to pass data.
(This link I used the swf loader component child and flash variables task Daya posted on Feb 15. However nothing loaded. The link wasnt a link i could display is in a browser. So i kept getting 0% when in preview mode.
Passing values from dashboard to dashboard with Flash Variables
Next I tried the following link. I did everything word for word and was able to display both files on the html page, but no link or connection between them existed. I would select a state and noting happened to the other swf files chart. Does this need to be in the Business Objects platform?
Dashboards 4.0: Connect to an external
Lastly , I used the link below. I followed everything and was able to get interaction from the parent to child however with only the files that were available on this thread. Their URL was this http://myxcelsius.com/wp-content/uploads/2010/10/child.swf?salesman=Schrute,Dwight. I get the concatenation but I dont get how this URL was generated? How do I develop my URL? My URL is able to display in a browser. My URL is
http://kln-ftvp/KLNPheonix//LinkToReport.htm?fqn=MyEnterprise.Public.graphtest&run=true
SWF Loader shows 100% instead of Dashboard.
Even with my URL being able to display in internet explorer, I still only show 100% and a blank screen. Can anyone help me with any of the issues I am having trouble with? Your help is most appreciated. Thank you.

It looks like you have more than one problems so it might be good to separate them out.
Issue 1 - Logging on to BusinessObjects
You say that when you try log on to the BO Platform you get the error message there is no central management server running on port 6400. I'm assuming you are trying to do this from the Dashboard designer.
Does it work when you try to log on from the web browser?
Make sure that you enter the correct system name in the system field when trying to log on from Designer. If you are unsure, either check what system name is used when you log on from your browser or check with your BO administrator.
Issue 2 - Passing values to a child dashboard
If you try to preview the dashboard in the designer, remember that the swf loader doesn't work in preview mode, so whatever you are trying to display won't be visible.
First of all you need to have 2 separate flash files that works independently of each other. The one that you are planning to use as a child flash, make sure that you create the flash variables so you can pass variables to it and use them to filter your data if that is your requirement. But hold off on that for now.
When you have 2 working flash files, save them both to the BI Launch Pad (or InfoView if you are on 3.1) and make sure they both work there. Then get the opendocument url for the child dashboard and try to open it in your browser directly using this url. If that works, use the same url in the swf viewer in the parent dashboard, save the parent dashboard back to BI Launch Pad and open it. It should now work.
Let me know if you have any problems with these steps.
Cheers,
Josh

Thanks in advance.

          Thanks Deepak but I think you don´t understand me.
          I would like the include works like a normal include. I have a jsp in my application
          and , when the client requests this jsp, in the jsp should be added the result
          of the other jsp ejecution that belong to other application in the same domain.
          Is this possible?
          Thank you very much.

How can split data into multiple sheets using an excel template

Hi all,
I'm using BIP 10.1.3.4.1 upgrated with the latest rollup patch, 9546699.
I followed the example inside the article "Real Excel Templates 1.5" (on the Tim Dexter's blog)
http://blogs.oracle.com/xmlpublisher/2010/05/real_excel_templates_i.html
and I built my report directly from an excel template containing only one sheet (plus the XDO_METADATA sheet), and for one sheet it worked fine !!!
Now I need to add more sheets to the template.... and I have two big questions:
1. if I need to create a second sheet which contains almost the same data (with a different layout), I saw that it is not possible to map a value to more than 1 cell....so if I map a value in the first sheet, I can't map it in the second sheet (because it's already used in the first one).
How can I map same values into two or different execll
2. if I need to create a second sheet which contains another dataset (completely different from the dataset in the first sheet), I can I do, considering that every BIP report is based on ONLY a data source.
Tim wrote: The most impressive, for me at least, is the sheet 'bursting'. You can split your hierarchical data across multiple sheets and dynamically name those sheets
but I didn't yet understand how this bursting it's possible.....considering what I said above.....
Surely I've a lack of knowledge.....but anybody can help me to understanding the "multiple excel sheets" black hole ?
I'll appreciate any kind of help
Thanks in advance

How to share variable between jsp and JSF?

hi:
I have code :
<h:dataTable binding="#{Tables.dataTable}" value="#{Tables.query}" var="currentRow">
<h:column>
<h:outputText value="#{currentRow['factorycode']}"/>
</h:column>
<%
//here I want get upon variable currentRow and process some field.
// but how java code I can get the currentRow,
//currentRow is a ResultSet object
%>
</h:dataTable>
thanks

EL cannot pick up scripting variables. It picks up attributes from scope only.
Similarly it doesnt set any scripting variables too.
<%
int g_nAge=12;
pageContext.setAttribute ("g_nAge", new Integer(g_nAge));
%>
${g_nAge}cheers,
