Trying to pass Hidden/Session variables from 1 JSP to 3rd JSP

Hellol JSP Gurus !!
This is a question on how a hidden or a value of a session variable can be passed from 1 JSP to a 3rd JSP, with the 2nd JSP as a Processing page.
For eg., here's the scenario
I have a Login page which has the hidden variables. Once the user enters the Login information, the info is validated in a LoginP.jsp (say, its a Processing page for the Login user/passwd info), which does a sendRedirect to a 3rd (Final) JSP which displays the values of the hidden/session variables of the 1st JSP.
In my case, for some reason, I am not able to see the value for the hidden or the session variables in the 3rd JSP - they are null values.
I am attaching some Duke dollars to who ever gives me the right solution.
Thanks a lot in advance

Use strings to set attributes;You can store any serializable object in the session. I doubt this will actually change anything.
Anything wrong with the above code ?Not that I can see ... A number of other things can explain why you're getting null values out of the session. For example :
- You are not using the implicit session obj in the 3rd jsp, but creating a new one and thus overwriting the one created previously
- the session timeout value is unusually low, and by the time you're getting to the 3rd jsp, the session is invalidated and you're getting nulls. Verify your server config, or call session.getMaxInactiveInterval() to check the value. Check also if the session is new ( session.isNew() )
Somebody already pointed this out : If the client does not support cookies and URL rewriting is not enabled, no session ID is returned to the server on a request, which the server then perceives as a new session.
- Another (remote?) possibility : your 3rd jsp belongs to another webapp (i.e you're redirecting to another app context).
If nothing of the above applies, post the jsp code and we'll try to help.

Passing Session Variable from PHP to Applet

I'm trying to pass a session variable from a PHP script to a third party applet. The applet needs to accept the variable as a string into a parameter. I think the htnl has to be dynamically created to turn the session variable into a string for the parameter value. Any suggestions ?

This is really a PHP question. You might get better results on a PHP forum.

Adding session variables from a recordset

I'm trying to create a session variable from data from a
recordset, can anyone help?
this is what I want the session variable to be from the
recordset:
<?php echo $row_rsStrata_plan['plan_str']; ?>
but I'm not sure where to go from here: $_SESSION[test] =?
Thanks,

Make sure you have <?php session_start(); ?> at the top
of your page
Then
$_SESSION['test'] = $row_rsStrata_plan['plan_str'];

Passing multiple session values from cold fusion into a flash movie

Hello all,
I know that to pass multiple variables into a flash movie
you could use the embed tag like this(with the & between each
variable):
<embed
flashvars="variable1=value1&variable2=value2"
></embed>
Now to pass a single session variable from coldfusion in i
did the following; which worked:
<embed
src="ASdb.swf"
FlashVars="UserName=<cfoutput>#session.userName#</cfoutput>"
width="550" height="400" autostart="true">
</embed>
Note that i had to use the cfoutput tags to get the value
stored in the variables. Now; i tried to do the same thing for two
session variables and the second one does not get read in. Here was
my code:
<embed src="ASdb.swf"
FlashVars="UserName=<cfoutput>#session.userName#</cfoutput>&testTypeID=<cfoutput>#session .testTypeID#</cfoutput>"
width="550" height="400" autostart="true">
</embed>
Can someone please tell me what I am doing wrong? Thank you
very much in advance.

Hold on there was a little error: My final code that did not
work was the following:
<embed src="ASdb.swf"
FlashVars="UserName=<cfoutput>#session.userName#</cfoutput>&testTypeID
=<cfoutput>#session.testTypeID#</cfoutput>"
width="550" height="400" autostart="true">
</embed>

Can I set a Session Variable from a Dashboard Prompt, using values that are

Hi All
Trying to set a Session Variable to an integer value, by letting users select a text value from the drop-down list on a Dashboard Prompt. The goal is to set the input parameter to the IndexCol function, but to provide the end users with a text description of what they are setting.
Select Value Set Variable Value
My 0
My Team 1
My Companies 2
My Teams Companies 3
Any suggestions on how to accomplish this? Certainly we could populate the drop-down from a data source, however I don't see how to populate a variable with something other than the values on the screen.
The IndexCol function is referenced in a Filter in Answers, and I'm thinking to populate a Session variable using the (Presentation) variable value set from the prompt. But how to do this? I see a reference to a function NQSSetSessionValue(), but cannot find documentation on how it works.
Any clue will be greatly appreciated.
Thanks

Hi kishore..
Looks like the link u have sent uses advanced SQL tab to set session variables. I want to know if I can use "set variable NQ_SESSION.myvar= @something" in the "SQL results" -while creating a dashboard prompt-.
Purpose: I want the session variable to be set based on whatever report that im currently in.
And i dont want to use presentation variables because im using a reset button in my page.
My reset script resets presentation variables and NOT session variables.
Thanks in advance

Problem accessing session variable from jsp

Hi!
I get an error retrieving a session variable from inside a JSP declaration scriptlet....
Something like this code in a JSP page:
<%!
public void funtion1() {
String parameter1 = session.getAttribute("parameter1");
%>I have seen that I have available getContextServer() method and from there I could call getAttribute("parameter1") . But the thing is that the attribute I want to retrieve was stored in session by another Jsp page.
Any solutions are welcome
Cheers
Victor

Appropriately the above is one the reasons also You cannot use JSP implicit objects from the declaration tag. However we can think of a small workaround by passing the reference like the one discussed below
<%!public void funtion1(HttpSession session) {
String parameter1 = session.getAttribute("parameter1").toString();
}%>
<% funtion1(session);%>Hope that helps :)

Passing variable from one JSP to another

Hi....
I am working on customizing Oracle Application(istore).
I need to pass variable from 1 JSP to another.
JSP 1 contains the following line of code:
<INPUT type="HIDDEN" name="soldtoCustPartyName" value="<%=soldtoCustPartyName%>">
How can I pass this to another JSP Page. The other JSP should take the 'soldtoCustPartyName' and find out the primary address country.
So please help me in getting variable passed from 1st JSP to next.
By default, 1st JSP is not fwded to 2nd JSP.
This is very very urgent...Please help.....

When you push the submit button on jsp1 - it goes to jsp2?
ie
// in jsp1.jsp
<form action="jsp2.jsp">
<INPUT type="HIDDEN" name="soldtoCustPartyName" value="<%=soldtoCustPartyName%>">
<input type="submit">
</form>
//Then in jsp2.jsp all you need is
request.getParameter("soldtoCustPartyName");This will pick up the value that is coming from the hidden field on jsp1

Passing variables from one jsp to another

Hi All,
I've searched thru the forum and can't find an answer to a prob I'm having, trying to pass a variable from one jsp to another.
in file searchBar.jsp i have
<%
String archiveSearch = "off";
%>
and
<%
if (userUtils != null && userUtils.getSearch().equals("on"))
%>
<a href="/webLayout/webSideBar.jsp?searchState=<%=archiveSearch%>onclick="archiveSearch = "on""></a>
and in file webSideBar.jsp
<%
String searchState = "off";
String archiveSearch = (String)request.getParameter("searchState");
%>
basically it will give me a variable archiveSearch set to on in webSideBar when the user clicks on the search button, but as it is it's not passing the variable from the searchBar.jsp to the webSideBar.jsp and I think it looks ok !!!! but it's not
Help

Looks good to me as well.
Couple of suggestions
1 - view source on searchbar.jsp - see what the generated source code for that link is
2 - Look at the url used to generate webSideBar.jsp. If its not in the address bar, right click the webSideBar page and choose properties.
Check to see what parameter was passed.
Are these pages in a frameset? Do you have to specify a target frame for your link?

Problems accessing session variables from a pop-up

I am working on a webapp and I when I click on a certain button I need to have a pop-up appear that will either prompt a user to enter log-in info if they haven't already, otherwise the pop-up just needs to display a report. Users can navigate around on the main page and select various reports so multiple pop-ups could possibly be opened. When a user logs in I save the login info in session variables, but for some reason whenever I click to have another pop-up open it always says that my session variables are null. Is there a way to have more global session variables so that multiple windows (the pop-ups) can touch session variables? Would there be a way to pass the login info in session variables back to the main page and then pass those session variables back out to each pop-up that opens? Thanks so much.

Have you got session cookies enabled?
The most common way to keep track of the session id is via a session cookie.
This cookie gets shared by all windows of the same browser session.
You are opening these pop-up windows with window.open?
Print out the session id <%= session.getId() %> on each page to see if it is the same.
Cheers,

Retrieving a session variable from a php script and putting it in an applet

I have a chat applet and i'm trying to have a session variable in one my php scripts be setted onto the user area of my chat. Would it start out by doing this?
<object codetype="application/java"

No.
Use the parameter tags.

Scripting - Passing and Enterprise variable from script to script

Hello all,
We are using UCCX 7.0_SR5
I am looking to be able to pass a captured variable from one script to another.
We use a message in queue where a caller waiting in queue can choose to leave a message and then that message is queued back into the sytem for the next available agent. When that agent recieves the message in queue they basically call back out to the customer leaving the message.
We capture a variable in the first script when they decide to leave a message. The variable holds the call back number that they enter into the system. There is a second script that presents these message in queue calls to the agents. We would like to pass that variable that holds the number enterend by the customer to the second script so that that number appears on CAD in the enterprise data fields. The reason behind this is so the agent has a number to call back in the event they don't reach anyone when the system calls back out and the message left by the customer does not contain a call back number.
How can I pass that variable from one script to another so it can be presented in CAD for the agents?
Thanks for any help and let me know if you need any further information.

You would use a "Get Call Contact Info" step to set your callerID variable, where the "Calling Number" attribute is set to your callerID variable.

Accessing variable from another JSP

Friends,
say, I have a Test1.jsp which has a variable "input". Is it possible to access this variable from other jsp "Test2.jsp"?
any ideas?
Thanks

hi hari,
there are essentially 3 ways of doing it....
1).Usage of Hidden Values
2).Using Cookies
3).Storing attribute value within the scope of request/session/appln
The choice is all urs....???

Pass the data back from the jsp page to the java code

Hi,
I have written an iView that receives an event using EPCF and extracts data from the client data bag.
I need this iView to pass the data back from the jsp page to the java code.
I am trying to do this using a hidden input field, but I cannot get the code to work.
Here is the code on the jsp page.
<%@ taglib uri="tagLib" prefix="hbj" %>
<hbj:content id="myContext" >
<hbj:page title="PageTitle">
   <hbj:form id="myFormId">
<hbj:inputField id="myInputField" type="string" maxlength="100" value="" jsObjectNeeded="true">
<% myInputField.setVisible(false);%>
</hbj:inputField>
   </hbj:form>
</hbj:page>
</hbj:content>
<script language=JavaScript>
EPCM.subscribeEvent("urn:com.peter", "namedata", window, "eventReceiver");
function eventReceiver(eventObj) {
     var url = eventObj.dataObject;
     var funcName = htmlb_formid+"_getHtmlbElementId";
     func = window[funcName];
     var ipField = eval(func("myInputField"));
     ipField.setValue(url);
     var form = document.all(htmlb_formid);
     form.submit();

After receive event, then call java script function "eventReceiver" and call "form.submit()".
But .. PAI Logic in Java code doesn't called ...
Where is my problme ?
Help me ...
Regards, Arnold.

Hi Arnold,
you should not do a form.submit yourself. Instead you can put a component called ExternalSubmit to your page:
ExternalSubmit exSubmit = new ExternalSubmit("EX_SUBMIT"));
exSubmit.setServerEventName("MyEvent");
This results in a java script funtion on the page which is called "_htmlb_external_submit_". If you call this function the the form gets submitted and your event handler is called.

Martin

Passing values to session variables from another application

Hi,
From an external application we are passing username and password for accessing the OBIEE Dashboard.In the url call we are passing NQUser and NQPassword. This is working fine.
To setup data level security we need to pass region id list also as request object. Then we can filter the tables by the value in the region id list for that user. If we use external table to pass the home_id list then the application is working fine by setting up row-wise init block. But we need request object from an external application to send the list. How can we accept the list from OBIEE RPD?
In the documentation it mentions about session variables - non system. But it requires an init block. How can we create a variable that accepts the values when user logins just like NQUser and NQPassword.
Please suggest.
Thanks.

Yes, this absolutely possible. You can get the details from the Web Services guide since it has all the necessary examples and more explanation. Thats why i did not include it in the blog. You can get it from page 213 of the Docs http://download.oracle.com/docs/cd/B40078_02/doc/bi.1013/b31766.pdf
