Sharing data between jsp's

how can i share different variable difined in one jsp to another jsp??
thanks!!!!

Are the two JSPs on the same user request? Use the request object to store the variables?
Are the two JSPs read by the same user but on different requests? Use the session object.
Are the two JSPs read by different users? Put the data in the application object.
Not sure how to use the pageContext, request, session, and application objects? Read chapters 11-16 of the J2EE tutorial: http://java.sun.com/j2ee/1.4/docs/tutorial/doc/index.html

Sharing data between two separate user sessions

Hi all!
I have been trawling my brain for a solution to this - any help will be appreciated!
I would like to create a single instance of a class but share that instance over more than one user session (two separate users but both running concurrently).
Just as you can pass data between sessions using ABAP memory - I would like to pass data (specifically an object reference) between two separate users that could even be logged in to two separate application servers...
Even a mini Client/server solution would suffice but I cannot figure one out!
Is this possible?
Many thanks for your thoughts in advance...

Hello N K,
sorry thats not possible. Sharing a data item / object instance requires at least a common physical memory. As this is not guaranteed between different app. server this is technical not possible.
With release 640 ABAP offers the new feature Shared Objects. These mechanism allows access by different users and some propagation to differnt servers.There is an interesting article on the ABAP SDN homepage
https://www.sdn.sap.com/sdn/developerareas/abap.sdn
For relases below more or less the database is the only chance to store data accross application servers (known to me). One exception might be the ENQUEUES which might (mis)used to store some Flags.
Kind Regards
Klaus

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.

Passing session data between jsp and servlet

I have a servlet that I pass data to my jsp.
I do a session.setAtrribute in the servlet. No problem.
I get the data no problem in the jsp that I call.
How do I pass this same data to the another servlet?
I basically have an array of values that I already have in the existing jsp that has been set in session.
When I call the secondary servlet, I don't have anything in this session variable related to my array.
Prior to posting to my next servlet, do I need to do another setAttribute inside the jsp to get the data passed to the servlet?
Thanks.

Two different things. The encoding adds this to the URL (after the page, before the query string
;jsessionid=ABC123 but only if the user isn't using cookies.
So in your example, you would do this (maybe):
<%
String url = response.encodeURL("Servlet");
%>
<form name="form1" method="post" action="<%= url %>?cmd=pay"> ... Or some modification.
So the difference between encodeing and using a post is that
1) encoding adds the jsessionid to the url string if necessary. It does nothing else
2) POSTing will send a request to the provided URL via the POST method, including the inputs of the form as parameters to the URL.
They really don't interact with each other. It is like asking what is the difference between the Color Orange and thr Size Big? They can both be applied to the same thing, or not... and have no real relation to each other.

Sharing Date between Projects

I can copy slides and use the Library to share data. I can
also combine multiple projects into a chain of projects. Is it
possible to have a source of data that can be shared accross
multiple projects? For example, lets say I have one slide I want to
use across 30 projects. Right now I can create a slide and copy it
into 30 projects. I can also create a project with the one slide
and have all projects run the second project, but starting a new
movie (I think) won't allow the user to go back to the previous
movie.
Is it possible to link data so multiple projects can point to
one or multiple files with the one or multiple slides. So when I
update that one slide, it updates it in 30 locations. I don't have
to update 30 slides. Its kind of lik building common pieces and
sharing them so you don't have to duplicate the same work multiple
times.
Shawn

Yeah, what you are talking about used to be called dynamic
link libraries or just dynamic linking - might still be, for all I
know. No, Shawn, it's not possible in Captivate. Not the way you
want to use it - sorry.
You've been around long enough to know the drill -

Sharing data between two canvases on the same form ?

Hello,
I have one form with two canvases and two data blocks.
Datablock A and datablock B are same tables.
The reason I split is so I can have a search field on canvas A, then after executing the query, I want to populate canvas B.
I'm having trouble sharing the data across both data blocks.
Note: I set up a relation in datablock B to correspond with A, and I've chosen field name "Horse" to be my master and detail item.
"When-button-pressed-trigger" --> Here is part of my code after the user presses the "Search" button (in datablock A).
     execute_query;
     SHOW_VIEW('CANVAS_HORSE');
     HIDE_VIEW('CANVAS_SEARCH');
     :fox_horse.horse := :fox_horse1.horse     ;                         GO_BLOCK('FOX_HORSE');
When I go back to my "FOX_Horse" datablock, why is the :fox_horse.horse field the only one populated? I though by creating a relation btwn the two blocks they would syncronize automatically ?
Any advice ?
Thanks,
Bob

Alex,
I have tried your suggestion, yet I'm still having a problem once I issue my execute_query command.
In my Search button I have this code:
BEGIN
:fox_horse1.horse := :fox_horse.horse;
GO_BLOCK('FOX_HORSE1');
execute_query;
END;
Note that FOX_HORSE is NOT a database block (as you suggested), but FOX_HORSE1 is a database block.
So when I click on the "Search" button I can see the :fox_horse1.horse field getting populated immediately, but then the system asks me if I want to save changes. When I say NO, the actual data block portion of my screen just defaults to the first record, so my exec_query show no effect at all.
What am I doing wrong in my search button trigger ?
Thanks so much for your advice,
Bob

Sharing data between CRM and Sharepoint

Does anyone have an easy way to share dynamic lists in CRM with Sharepoint? We basically have a client list/view in accounts in CRM (all are online services with Microsoft 2013) and want to have it or a variation of it in sharepoint, but we want the data
to be dynamic. Wondering about BCS or using dynamic spreadsheets. Thanks.

Hi,
Yes, this is what EPMA is meant for. You can create and share dimensions between applications of different type. In the property grid of any member at dimension library you can choose the category and edit the properties in selected category of the member (Planning, Consolidation (HFM), Essbase, etc.).
Further details are in below:

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.

Sharing data between swf files

Hello,
I have a login.swf file which authenticates the user. Once login is successful I want redirect to loggedin.swf file and pass some user information to the loggedin.swf?. How do i do it? I dont want to use shared objects as users may prevent saving on to local machine. I dont want to send it in URL either. I want something like hidden variables in html. Is it possible.
Thanks,
Bharani

Hi
I have mutiple swf files in single page each having its sound attached to it.
Now I want one sound to play at a time while all rest swf's sound to be mute.
When user clicks second swf then first swf sound to be mute and second's swf sound to play and all rest swf to mute.
Similarly when he clicks third then third's sound to play while rest all swf to be mute.
I have already implemented swf with sound attached.
But they all are playing at a time.
How this control can be implemented ?? Number of swf files can vary.
Any help??

Transferring data between JSp's

I have a servlet, PC502, which I invoke and use PC502.jsp to display the results. I have a clickable button so if the user wants to see more account information I invoke servlet PC503, and use PC503.jsp to display the results. Within the PC503.jsp I want to reference and display a field that is part of the PC502 servlet. I thought that by using the useBean,
<jsp:useBean id="pC502Command" class="pc502.PC502Command" scope="request"></jsp:useBean>
I would be able to reference <%= pC502Command.getOp02o__Debt__Name() %> within the PC503.jsp, but PC503.jsp displays a blank for the DebtName.
My question is how can I reference a property from the PC502 bean while I am in the PC503.jsp. Each servlet is in its own package, and project. So I have project PC502, which has package pc502, which has command PC502Command, and servlet PC502Servlet. The same holds true for PC503.
Any help would be appreciated.

Hello,
I do not think you can reference a PC502 object from PC503, since they reside in their own package structure.
I have developped a few JSP/Servlet applications and have come to the conclusion that the best way to get the information across is to have PC502 set a session variable and let PC503 get the info from the session.
Similarly, you can put information in the request object.
session.setAttribute("paramName", "hello");
String object = (String) req.getParameter("paramName");So now, the string object has a value of "hello".
Hope this helps,
Haig

Sharing data between two Web Apps

Hi,
I have got two web applications that share a MySQL database accessed by
Kodo JDO. I have tremendous difficulty to share the state that one web
application writes to the database with the second web application. The
data seems to stay in the cache of the first app and I have not found a
way to flush the data to the SQL database, so that the second can read it.
I do a refresh on the relevant object within the second app. The problem
seems to be flushing the cache of the first app.
Best regards
Wolfgang
PS: To Solarmetric: Thanks for this wonderfull technology. I am building a
complex database application, without having to learn SQL.

Hi Greg,
this:
properties.setProperty("kodo.DataCache", "false");
does not do the trick. There is no difference in behaviour. To use
kodo.RemoteCommitProvider I would need the performance pack at 900 bucks a
pop, which is not an option right now.
Best regards
Wolfgang

Hi Wolfgang,
Are you using Kodo's Datastore cache in both web apps? I suspect that what
is happening is that the data actually is being flushed to the database
appropriately (assuming that you commit your transactions), but that your
cache in your second app has stale data. Could you turn off the datastore
cache in both apps just test that hypothesis?
If your applications start to work as expected with the datacache off, then
you should check out (assuming you're using Kodo v. 3.1.3)
http://www.solarmetric.com/Software/Documentation/3.1.3/docs/ref_guide_event.html#ref_guide_event_conf
That section of doc describes how to get the datastore caches in the two
