Using a variable as a value in jsp:param

I was wondering, I have a String variable, vid_1, and want to use a jsp:include and pass that in as one of the parameters. How can I do this? I have to do some testing to make sure vid_1 is valid and set a default if not. It contains a number referring to which video needs to be displayed.
Is there anyway I can get this value to be used in jsp:param value?

Well,First thing you haven't pharsed your question properly.
Anyways as per my understading.
The first thing is make use of in this case as your defined requirement states you need to make use of variables of both the JSP's which need compile time include not at the runtime.use of
<%@ include file="url" %>would be more appropriate as you want to use the variable of parent jsp to the child one.
Anyways if you are thinking to apply a solution using <jsp:include/>
<jsp:include page="url">
<jsp:param name="paramName" value="<%=stringVariable>"/>
</jsp:include>and extract the paramName's corresponding value as a request parameter in other JSP.
Hope that might answer your question :)
REGARDS,
RaHuLRaHul,
Thanks for the reply. The second example you gave is what I was trying to do. I thought I did exactly what you have there and it was not working. I will check it over again and post back on here when I have a chance.
For now I was trying to use c:set to save the variable in the request and then using the EL expression ${requestScope.variable} to put it in the <jsp:param> element. I had some things working and others not when I quit. Hopefully tomorrow I can give you a full report and we can get this worked out.
Maybe my problem is something else? Look at this post of mine:
http://forum.java.sun.com/thread.jspa?threadID=5236252&tstart=10
Thanks so much for the help.

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.

Report script - using substitution variable with multiple values

Hi All,
Substitution variable with multiple values is not working correctly with Report scripts. Can you please let me know what is the syntax to assign multiple values to a sub variable using maxl:
alter database samp.samp set variable 'ExtractQuarter' 'Q1,Q2,Q3,Q4';
alter database Samp.Samp set variable 'ExtractQuarter' 'Q1:Q4';
I tried both of the above but they are errored out with the below error:
Error: 1001005 - Unknown Member [Q1:Q4] in Report.
my requirement is different for both Actual and forecast data extract so i would like to make use of this variable to extract whole year data for Forecast and current quarter data for Actual with out duplicating the report scripts for both processes.
Thanks,

Passing javascript value to jsp param

Hi all,
I want to be able to pass the return value of function getUrl() to jsp param...Is this a correct way? it's not working.... What should I assign to the value of param?
<HTML>
<HEAD>
</HEAD>
<script language="javascript">
function getUrl()
     var url=window.location;
     return url;
</script>
<BODY>

thank you for your time and assistance

Hi all,

thank you for your time and assistanceThis can't be done, since the jsp call will be exercised on the server, before the page gets sent to the user, while the javascript gets performed on the client (well after the jsp is done its job).
An all server-side solution would be what you needed:
<HTML>
    <HEAD>
    </HEAD>
    <BODY>
        <jsp:include page='GetFileServlet' flush="true" >
            <jsp:param name="url" value= "<%=request.getRequestURL()%>"/>

Using substitution variable with multiple values in Maxl Command

Hi All,
Is there any option to use multiple values in 1 substitution variable and use them in a Maxl command.
alter database $app_name.$db_name clear data in region '{CrossJoin(CrossJoin(CrossJoin({StrTOMbr(&Months)},{XXX, YYY}),{StrTOMbr(&CURYR)}), {ZZZ})}'physical;
In the above case
Maxl is not working if I have multiple months in &Months Substitution variable.
Let me know if there is an alternate option to implement this.
Thanks
Sathish

What is the value of &Months?
If you put that exact value into the code, does it work?

Need to reference a cell using a variable or cell value.

Hi.
I am trying to build a master sheet and then have sub sheets that detail the information from the master. My master sheet looks like this:
1 | 101 | Bob | Smith |
2 | 104 | Sally | Jones |
3 | 108 | Tim | Abbott |
Then on separate sheets I want a summary for each line like this:
1 | Name | Bob |
2 | ID | 101 |
Now, I know I could just build this by creating references to the master sheet, but in reality my sheets are far more complex and I really need to be able to reference them by line number. So I would like to have a hidden cell (say AA1) on each summary which designates the line and then reference Master:B{AA1}. I did this years ago on excel but have no idea how I did it or howo to do it in Numbers.
Any help is greatly appreciated.

Hi 86,
Rearrange your table then add another table to find the result:
A2 in Table 1-1 will find the earliest date in Table 1 without having to sort Table 1.
A2 contains this formula
=MIN(Table 1::A)
B2 in Table 1-1 uses VLOOKUP to find which ID matches that MIN date.
The reason for rearranging your table (Table 1) is that VLOOKUP compares a search value to the values in the leftmost column of a specified collection.
(in this case, it looks in the leftmost column of the range Table1::A:B, then returns a match from column 2 of that range).
I forgot to include "Exact Match" in the VLOOKUP formula. Is that what you want, or "Close Match"?
Edit: I don't suppose that matters because MIN will always give an exact match. Duh!

Ian.

Web Forms using substitution variables with multiple values

Hi,
I am trying to select a substitution variable in a webform (Hyperion Planning 11.1.1.3) with multiple values in EAS, but is not working does somebody knows if this an expected behaviour.
I allready try ex.
&Months = "Jan","Feb", "Mar"
&Months = Jan, Feb, Mar
&Months = Jan:Mar
Please let me know something, since as far as I recall in previous versions of Hyperion Planning this was possible.
Kind Regards

We experienced the same issue, our requirement was that for the first half of the year the substitution variable was = Oct and for the second part of the year Jan:Dec. We were lucky that for the second scenario we had a Total Year member as well (that at the bottom level is Jan:Dec). So on web form we picked Level0 descendants of the substitution variable. That worked fine but not the range.

Using jsp:param

hi,
i am new to java and jsp programming and i am trying to use jsp:param nested in my
jsp:forward statement.
if i specify a value in jsp:param my page would display properly. however when i passed a variable in my jsp:param i get the error:
Generated servlet error:
[javac] Compiling 1 source file
C:\Program Files\Apache Group\Tomcat 4.1\work\Standalone\localhost\star\jsp\Meeting_CreateMinutes_jsp.java:135: cannot resolve symbol
symbol : method encode (long)
location: class java.net.URLEncoder
pageContext.forward("Meeting_ActionItems.jsp" + "?" + "docno=" + java.net.URLEncoder.encode( carno ) + "&" + "formmode=" + "Add");
^
1 error
this is the snippet in my jsp page that (i suspect) caused the error:
<% long carno = newcar.getDocno(); %>
<jsp:forward page="Meeting_ActionItems.jsp">
<jsp:param name="docno" value="<%= carno %>"/>
<jsp:param name="formmode" value="Add"/>
</jsp:forward>
my question is : does jsp:param do not accept variables as values?
thanks in advance.
best regards,

<% long carno = newcar.getDocno(); %>Change this part as
<% String carno = ""+newcar.getDocno(); %>

Furthermore i wanna know about the use and what are presentation variable
So pls help, asap

And what do you don't know?
How to set a presentation variable in dasboard? Answer: use a prompt see in here: http://gerardnico.com/wiki/dat/obiee/presentation_variable
How to use a variable after is set? It is very well described in http://shivabizint.wordpress.com/2008/10/02/oracle-bi-ee-variables-overview/ @{var_name}{defaultvalue}
you can filter data:
- static 'col = value'
- is prompted (in this case it will be filtered on value that comes from navigation or from a prompt)
- on other request
- finally from a variable
you can use variable to make for example topn and the user wants to modify number of topn
so you set a variable from a prompt and use that variable on topn(value, @{var_nr_values})
you can find a lot of docs on this topic, kart give you some links...
Make research, and when you have a problem please come back with the isue and we happily try to help...

How to use jstl variable in a jsp page

Hi all,
I am new to JSTL and i want to access the value of jstl in jsp.
when i use the tag like below it is displaying the value ""
<c:out value="${ack}"/>
But as ack is string, i want to convert it into int. and i have written like
<c:set var="ackvalue" value="${ack}"/>
and int ack = Integer.parseInt(ackvalue);
But it is showing error like varialbe can not be resolved: ackvalue
can anybody please help me regarding this?
Waiting for your warm response.
Thanks in advance

Hi,
Thanks for your immediate reply.
I am able to display the ackvalue when i am using
<c:set var="ackvalue" value="${ack}"/>
and <c:out value="${ackvalue}"/>
But my actual requirement is to use the ack value in
switch statement. if i can assign the value to a
String variable, then it si easy for me to proceed.
Please help me in this regard.
Thanks,You can use the c:choose, c:when and c:otherwise tags
<c:choose>
    <c:when test = "${ackvalue == 1}">
           //do stuff
    </c:when>
    <c:when test = "${ackvalue == 2}">
           //do some other stuff
    </c:when>
   <c:otherwise>
          //stuff
    </c:otherwise>
</c:choose>ram.

Using JSTL variables in JSP or Javascript. Possible ?

Hi All,
Is it possible to share or use the variables which are declared are used by JSTL in JSP expression or scriplet code and in Java Script.
Example:
This Works:
<fmt:set var="test" value="JSTL" />
<fmt:out value="${test}" />
But, this gives error:
<% out.println(test) %>
And passing the value of variable 'test' to Java Script code also gives error.
How to use JSTL variables in JSP and in Javascript ?

By default, JSTL variables are kept in servlet
attributes. Default is to store it in the page
context. You can make it request/session/application

Can anyone advise how to access JSP variables in JSTL?
Can it be done as the same method through request/session/application scope?

<input type="button" name="b" value="test" onClick="test(5)">
<input type="text" name="v" value="0">
In short, I am trying to pass JavaScript value to JSP variable. I hope that it is possible to do that. If it is possible then how can I do it. I want to assing the variable x passed to the JavaScript function called test to the JSP variable called num.
Regards,
Ageel

Thank you for your reply,,,
I think then the only way to do it is to post the
value on the server and then use request.getParameter
method in jsp code
but the question now how can I post values to the
server using JavaScript without reloading the pageyes... you can to it by create a new popup window which will submit the value to server after page was loaded... then, server return a value to the same window in html/jsp page which then using javascript to set it back to the opener and close up the window... however, this is not a good choice unless you have no other alternative...
>
There is other possible solution
if I can get the text field value from the same page
without reloading it that would work fine and will
solve my problem, is it possible?yes... you can get the value from the textfield...
for example :
function showValueInTextField()
alert(document.forms[0].elements["mytextfieldname"].value);
>
My final question> can jsp change things on the same
page without reloading it. I mean can it work like
JavaScript so that I can use it's internal functions
instead of using java script :S
not really know what you trying to say here...

Using drop down list value in jsp with AJAX

Hi All,
I am having a jsp page , which contains a dropdown list.
When user selects an item from the list, I've to pass this value to my java class to access other related information to be displayed on the same page without refreshing/submiting the page.
Now the problem is, i am getting selected value in java script function but how to use this variable & pass it to java class.
I googled a lot and found that AJAX could be used for it. Please suggest me that -
1) Whether AJAX is the only approch ? I am affraid of it bcoz I hvn't work on it.
2) Is there any other workaround by which i can use that value & call my java class method, without refreshing the page?
3) If I've to use AJAX, plz help me if u've similar example. I went through the w3 scool, but not getting much idea.
Kindly help me, the problem is very urgent with the strict timeline.
Thanks & Regards,
Sneha

3) If I've to use AJAX, plz help me if u've similar example. I went through the w3 scool, but not getting much idea.Well then you'll have to do more work. Do a Google search, research more. Ajax is such a broadly discussed topic, you have to be very bad at your work if you cannot find decent resources for it in the context of your problem domain.
To give you a hint, I suggest you look into JQuery. It is quite a popular Ajax javascript toolkit.
