Jsf passing parameter between jsp's

Hi
I have my main.jsp and another screen which i call object.jsp
the object.jsp can present an object in multiple ways : add, edit, view
i have 3 buttons in my main.jsp add, edit, view. I want to pass a parameter from main.jsp to object.jsp such that object.jsp will know in what state its being loaded... how do i do this?
Thanks..

session?
as the article says :
To avoid these problems, developers might use session-scoped variables instead. This fixes both of those problems, but adds new ones:
A single user cannot have two windows open simultaneously; session-scoped variables are global to the user. So, for instance, a user could not work with two different search results simultaneously.
Back button support is highly limited, since navigating back can't magically restore the session to its old state.

Passing parameter between jsp pages

Hi
I'v got the following problem: I have an jsp page that shows result of sql query as a list of 5 items, if there are more items returned - it shows first five, user is able to see more by clicking to a link which shows him the same page with next 5 items etc. The piece of index.jsp file with that link looks like that:
        <html:link action="<%=(String)request.getAttribute("actionMod")%> module=... name=... styleClass=...>and at the end of initSearchAction I have:
req.setAttribute("actionMod","initSearch.do");Action is defined:

        <action path="/initSearch"
                type="...list.InitSearchAction"
                name="productListForm"
                validate="false"
                scope="request"
                unknown="false"
                >
                <forward name="success" path=".search"/>
        </action>      .search is defined as
<definition name=".search" extends=".main">
        <put name="body" value="/list/index.jsp" />
</definition>The problem is when I set a paramter in initSearchAction like that:
req.setAttribute("handle",h);and try to read it next time when initSearchAction action is running, parameter h is null. I need that to pass handle to stateful session bean that holds important information that need to be static during a session. Can anyone tell me how to pass that handle in some other way?

ania

now it works :)
I'm new to this things so I'm not familiar with all those sessions and requests...
thanks a lot

Passing parameter between JSP

Hi All,
I want to pass a parameter (let us say data from a text box) from one JSP to another on an event (when 'Submit' button is clicked.). Can you please let me know how to go about this? Any sample codes or any other kind of help will be greatly appriciated.
Thanks in advance.

hi,
It's quite easy, just go thru the following code.
one.jsp
<form action="two.jsp" method="post">
<input type="text" name="name"/>
<input type="submit" value="Press"/>
</form>now receive the value in two.jsp and print the same.
two.jsp
<%
String name=request.getParameter("name");
out.print("Your Name -->"+name);

Passing Parameter between Methods

I have some problems because i don't really know how to pass parameter between methods in a java class.
How can i do that? below is the code that i did.
I want to pass in the parameter from a method called dbTest where this method will run StringTokenizer to capture the input from a text file then it will run storeData method whereby later it will then store into the database.
How can i pass data between this two methods whereby i want to read from text file then take the value to be passed into the database to be stored?
Thanks alot

In a nutshell, you don't "pass" parameters. You simply call methods with whatever parameters they take. So, methods can call methods, which can call other methods, using the parameters in question. Hope that makes sense.

Passing parameter between two applets

hi all,
i want to pass parameter between two applets. in other words, when user clicks the button; close the running applet, pass parameter to another applet and run another applet.
now i think that could be, ( creating a parameter table in database, when user click on button write parameters to table and stop active applet and run other applet. when other applet runs in init methot it takes parameter from table). but it will be very indirect way.
if you have an idea or information, plesae tell me.
thanks for your interest

Urgent! pass parameters between jsp pages

Does anyone can give an example about how to pass parameters between jsp pages?
This is what I do:
pageContext.forward("pag_loginc.jsp?p_idusr=" + strUsr + "&c_password=");
But when deployed is not working.
Help is needed.

can you put that stuff in the session context in the first page, then pull it out in the second page?

Passing values between jsp and php

hi there, is it possible to pass values between jsp and
php? i really need to find out the way if there is
any. thanks in advance
-azali-

Yes, there are a few ways to do this.
1) Think about using Cookies.
2) Maybe use a Redirect passing the values in the Query string.
3) Retain the data in a repository in the back end.
4) Using Hidden fields within your pages.
I am sure you can use these Idea's for a base to develop other methods on how to pass values back and forth from JSP -> PHP and vice versa.

Using Go URL to Pass parameter between dashboard

Hi All,
I am trying to pass parameter using GO URL functionality from one dashboard analysis field to another dashboard.
The navigation is working properly but the parameter is not getting passed, I am not sure why.
The Called dashboard has a analysis which has IS PROMPTED filter attached to it for the passing filter. I tried various ways to make this work
Option 1
In the calling analysis, I am using a Narrative View and inside I have used the below code.
<a href="saw.dll?Go&Path=/shared/MI/_portal/Client-MI&Page=Supplier%20Detail%20Tab&Action=Navigate&P0=1&P1=eq&P2=Dim%20Supplier.Supplier%20Name%20Current&P3=1+%22STR%20LTD%22"> @2[br/]
This one navigate but filtering is not happening
Option 2 (My first preference will be this option)
Also I tried to provide custom Data Format under the column Properties
[html]"<font class="nav" onclick=\"JavaScript:GoNav(event, '/shared/MI/_portal/Client-MI/Supplier Detail Tab','Dim Supplier','Supplier Name Current','"@"');\">"@"</font>
This ends up giving error
Type mismatch of catalog object /shared/MI/_portal/Client-MI/Supplier Detail Tab -- expected , got .
Error Details
Error Codes: UVWDR6UA
Also, both the tabs (Called and Calling are under the same Dashboard)
Can anyone please let me know, were I am making mistake. I tried refereeing Oracle documentation but still no result.
Thanks

Looks like you've got it almost right - just an extra unneeded "
<a href="two.jsp"?ant=<%= ant %>"><%=antName%></a>
which should render on the page as something like
My Ant Task
When you click the link, it should pass that parameter, and you can get it via request.getParameter().

Pass parameter between programs

Hi,
I need to pass one parameter between 3 programs :
That is the actual flow of my parameter.
SAPF110V -> RFFOBE_I -> which include ZRFFORI99B)
get param <- RFFOBE_I <- set param
with statments
SET PARAMETER ID 'ZDBL' FIELD p_doublon.
GET parameter ID 'ZDBL' FIELD p_doublons.
But unfortunatly it doesn't work :/ (value of my param = 0)
I can run the include program in debug because it is run in background...
I can't use a Ztable
Any idea to pass value between this flow ?
Thanks,

Hello,
The value which you want to pass between the programs can be stored in the SAP memory space by using the IMPORT and EXPORT to MEMORY ID statement.
EXPORT <internal table/variable> to MEMORY-ID 'MY MEMORY'.
Above statement will keep the value in SAP memory by creating a memory named as 'MY MEMORY'.
IMPORT <internal table/variable> from MEMORY-ID 'MY MEMORY'.
Above statement will get the value from SAP memory space.
But while using the above statement please consider that all the three programs should be run in the same session because the Memory that you are using will automatically be cleaned up by the Garbage collector as the session ends.
Hope it helps.
Thanks,
Jayant.

Portlet event link to pass parameter between portlets

Ok list, I followed the documentation Adding Parameters and Events to Portlets
PDK Release 2 (9.0.2 and later) and tried to make a portlet that pass parameter to another portlet using event link. I created the supposed parameter in the page and made the correct association to the receiving parameter portlet. The case is: The parameter is not caught in the receiving parameter page.
This is my event link jsp code:
<%
String sImgPath = PropertiesReader.getProperty(PropertiesReader.KEY_IMAGES_PATH);
PortletRenderRequest portletRequest = (PortletRenderRequest)request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
// The portlet definition in provider.xml includes the following:
// - Event "submit" with event parameters "funcionalidade"
String eventSubmit = EventUtils.eventName("submit");
String eventParamFuncionalidade = EventUtils.eventParameter("funcionalidade");
// Build up the list of parameters for the "submit" event
NameValuePair[] eventSubmitParams = new NameValuePair[2];
// Give the 'funcionalidade' event parameter the constant value 'chat'
eventSubmitParams[0] = new NameValuePair(eventParamFuncionalidade, "chat");
// The event name must be passed as a parameter on the URL
eventSubmitParams[1] = new NameValuePair(eventSubmit, "");
%>
<TABLE CELLPADDING="0" CELLSPACING="0" BORDER="0">
<TR><TD><a href="<%=PortletRendererUtil.constructLink(portletRequest,   portletRequest.getRenderContext().getEventURL(), eventSubmitParams, true, true)%>"><IMG SRC="<%= sImgPath + "menuButChat.gif" %>" BORDER="0"></a></TD><TR>
</TRABLE>
And this is my receiving parameter jsp code:
<%
String sFuncionalidade = "";
PortletRenderRequest portletRequest = (PortletRenderRequest)request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
// Get the portlet definition - needed to get the public portlet parameters
PortletDefinition portlet = portletRequest.getPortletDefinition();
// Get the public portlet parameters
ParameterDefinition[] parameters = portlet.getInputParameters();
// Display all values for each of the public portlet parameters
for (int currParameter = 0; currParameter < parameters.length; currParameter++)
String name = parameters[currParameter].getName();
out.println(" <p>name = " + name + "</p> ");
// Get the parameter values
String[] values = portletRequest.getParameterValues(name);
// Display the parameter's values.
if ( values == null )
// Null array indicates no values for this parameter.
out.println(" <p>values i null</p> ");
else
out.println(" values nco i null ");
// Loop through each of the values and display non-null values on a separate line.
for ( int j = 0; (values != null) && (j < values.length); j++ )
sFuncionalidade = values[j];
out.println(" <p>" + sFuncionalidade + "</p> ");
%>

Where do I miss ???
Any help will be appreciated.
Regards,
Leandro.

Leandro,
Few things which you might want to cross check to see if we are
on the right track :
1. Page containing Parameter receiving portlet contains a
paga parameter mapped on to its public parameter.
As per your example, parameter receiving page should have a page
parameter with name - "funcionalidade" - and portlet's corresponding
parmeter should be mapped to this page parameter. This can be
done through "Parameters" tab in the Page Properties screen.
2. Page containing Parameter passing portlet contains proper event
mapping.
As per your example, we have an event called "submit". We should
be able to see "submit" event under "MenuColaboracao" portlet.
When this event is raised, select which page should receive the event
data. As soon as a page is selected, this page's public parameters
are displayed below. Beside that we must be able to see a choice box
which displays four choices one of which would be "Event Output".
Map this output to the event parameter.
Hope it helps.

Pass parameter between uix page

Hi, I am new to JDeveloper UIX technologies. I have created two uix page: page1 is built on a view. Page2 is on a table. How do I pass a parameter (customer_id) from page1 to page2?
Any help is appreciated. Thanks ahead!

You can get the sample code for your answer here:
http://otn.oracle.com/sample_code/products/jdev/index.html
Download sample code with title:
Passing values between pages
Or alternatively your can keep the customer_id in the session during ActionForward then passing back the value into a textbox in page 2.
Code in ActionForward:
request.getSession().setAttribute("customer_id", value);
Code in UIX Page 2:
<textInput text="${sessionScope.customer_id}" name="code2"/>
Thanks.

Pass value between JSP pages

I would like to pass values between pages.
I don't want showing up on the url. Ex: some.jsp?param=value
I don't feel it's safe.
It's not coming from form either....
How can I hide the value and pass it to next page?
I want to pass the value when the user click on a hyperlink
Thanks In Advance.

Client side information is never safe no matter what you do. If the values don't end up in the url, they are always present SOMEWHERE in the html content.
If you don't want the values to end up in the url, rework the page so it DOES do a post form submit. You could turn the hyperlink into a javascript call that submits the form for you.

Passing parameter between JSF pages

I need to pass a parameter value between 2 different JSF pages.
The reason I need to do this is to be able to know which JavaBean (A or B) called the other JavaBean (C).
Can I somehow set a parameter within the JSF page and retrieve it in the second JSF page for my backing bean to read?
Thanks in advance.

A co-worker of mine helped me fix my code to make it work!
Here is the final solution in case someone else needs to do the same thing in the future:
In the main JSF page that calls the second JSF page, the following code was added at the beginning of the page in the JavaScript section:
<% session.setAttribute"className", "CcmReassignEmployeeBean");
And in the Backing Bean of the second JSF page, the following code was used in the action listener used to transfer the data:
HttpSession session = (HttpSession) context.getExternalContext().getSession(true);
String className=(String) session.getAttribute("className");
It works great! Thanks!
