FOREACH var IN REFDATA

Hi everybody,
some info on FOREACH var IN REFDATA. If the filter restriction is such that there is not existing data within the filter restriction, then the function will no be executed at all (and hence there is no looping over REFDATA).
The typical example for using FOREACH var IN REFDATA is when moving actual data from an actual cube to a plan cube. IF the filter restriction then is e.g. VTYPE = 20 (where 10 = actual and 20 = plan) AND there is no plan data existing in the cube at the moment of executing the function THEN the coding in the function is not executed at all since the buffer is empty.

Help on aForeach in Selection and Foreach in Variable

Hello,
The planning function of type formula reads the reference data automatically.
The statement should do the job.
{ KEYFIGURE, 10 } = { KEYFIGURE, 20 }.
If you write
DATA VERS TYPE 0VERSION.
FOREACH VERS IN REFDATA.
{ KEYFIGURE, 10 } = { KEYFIGURE, VERS }.
ENDFOR.
the system would not do the job. The system will not read in data from version = 20.
You can tell the system, which reference data you use by
a) writing it in an operand at the left side of an expression
{ KEYFIGURE, 10 } = { KEYFIGURE, 20 }.
b) using a global variable and using this variable in an operand.
DATA VERS TYPE 0VERSION.
VERS = VARV( GLOBVERS).
{ KEYFIGURE, 10 } = { KEYFIGURE, VERS }.

Hi,
You can use session variables to set the value. There are apis available for setting and getting the session variables.
declare
persons number;
begin
p_session.set_value(
p_block_name => blk,
p_attribute_name => 'A_FLIGHTNO',
p_value => to_char(NULL)
persons := p_session.get_value_as_number(
p_block_name => blk,
p_attribute_name => 'A_NOF_PERSONS');
end;
Thanks,
Sharmila

How to name items that are coming from forEach loop

I have an arraylist of String[]'s that I need to display on the screen. I am sorting through the arrayList and pulling the values I need and displaying them without a problem. Two of the values from the String[] the user can modify. The problem is that when they modify it they aren't being mapped back to the original ArrayList when I submit the form. There seem to me to be two possible answers... A. It can't be done, or B I don't know what to name the values.
So here is the code I am using and then I'll explain how I've worked around the problem.
<table><tr>

          <th><fmt:message key="T895Form.deNumber" /></th>

          <th><fmt:message key="T895Form.calcOptions" /></th></tr>
          <c:set var="counter" value="0" />

</table>Right now when I submit the page I get String[]'s returned for each of the columns... I thing use the position string[] that contains the position the row was pulled from the arraylist at and loop through the arrays and put them back in the arraylist... that way when I revisit the screen the arraylist still contains the users changes...
This all works.. but I was wondering if there was a better way to do this. .. ie name the deNumber input something else that will map directly back to the arrayList?
Thanks in advance... but again, it works the way I'm doing it... it just isn't very pretty.

There seem to me to be two possible answers...
A. It can't be done, or
B I don't know what to name the valuesIf you are talking standard JSP/JSTL the answer is A
however as part of Struts, they developed indexed properties.
You can use the jakarta commons BeanUtils package to automatically populate
Therefore the answer is B if you consider this approach.
Each individual textfield gets numbered. This is resolved by the BeanUtils package.
You don't NEED struts to do this. You can use the BeanUtils class on its own. I haven't done too much research into it though :-)
<INPUT type="text" size="5" MAXLENGTH="5" name="deNumber[${status.index}]" Linkies:

c:forEach use .......need help

I am making a form of registering details of competitive exams.in this i am using the jstl for fetching the values fromthe database
like qualification table is master table and the eligibilty table .
these two tables are drop down list and depend on one another
in the sense ...eligibility table when u select multiple values from it then an event onblur will make the changes in the qulaification drop down list.
the list of values from the master tables are taken to the bean first and then into the form and also all the getter and setter methods are also there in it
the code for it is as follows:
bean
private String examinationName;
     private List eligibilityList = new ArrayList();
     private List qualificationList = new ArrayList();
     private List sourceList = new ArrayList();
     public CompetitiveExamBean() {
     eligibilityList = DAOMaster.getQualificationMaster();
     if(eligibility!=null) qualificationList=DAOMaster.getQualificationDetail(eligibility);
     sourceList = DAOMaster.getSourceList();

Problem using c:forEach

Just the same way as you do in JSP. Since JSF 1.2 you can use unified EL #{ } in c:forEach.
You can also use Tomahawk's [t:dataList|http://myfaces.apache.org/tomahawk-project/tomahawk12/tagdoc/t_dataList.html] by the way. It is more efficient.

JSTL forEach inside html form

I am using JSTL to display data in an editable menu. The data is retrieved from a database and the user may change it if required. The problem is that I get a blank page inside the forEach tag.
%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<sql:query var="rs" dataSource="jdbc/agenda">
SELECT * FROM cardapios WHERE username="${pageContext.request.remoteUser}"
</sql:query>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<form action="../ChangeMenu" method="POST">
Everything I write here I can see!!!
<c:forEach var="r" items="${rs.rows}">
Restaurante: <input type="text" name="restaurante" value="${r.restaurante}" /> I cant see it!!
Here I have many <input type="text" ..... etc />
</c:forEach>
<input type="submit" value="Salvar" />
</form>
</body>
</html>Well, if I remove the form action, it works properly. So, the data is being retrieved from the database.
Also, do I really have to use <c:forEach> since it will always retrieve just one line from the table? Is there any other way I can get the data from "rs" ?
Thanks!

If you know for certain there is exactly one and only ever one row returned, then you can just access it directly:
<c:set var="r" value="${rs.rows[0]}"/>With regards to the query, it would probably be better using parameter rather than the variable directly:
<sql:query var="rs" dataSource="jdbc/agenda">
SELECT * FROM cardapios WHERE username= ?
<sql:param value="${pageContext.request.remoteUser}"/>
</sql:query>I don't think that would change the functionality, but it would prevent SQL injection attacks.
I don't see how removing the form action would change the display of the html page.
My suggestion would be to view source on the generated HTML page, and see what is being produced by running the page.
Did the query return the results that you wanted? Is it generating valid HTML?

Formating table using c:forEach

Dear fellow Java Developers,
I have an object in session called grid whose properties consist of several array lists. I am trying to iterate through each ArrayList so that each list has its own column side by side in one HTML table. Currently the page displays the data but does not build the table correctley. I am having a lot of trouble correctly building the HTML table. Here is my JSP code:
<table border="1">
     <c:forEach var="cusID" items="${grid.cusID}">
     <tr>
          <td>
               <c:out value="${cusID}" />
          </td>
     </c:forEach>
     <c:forEach var="cusName" items="${grid.cusName}">
          <td>
               <c:out value="${cusName}" />
          </td>
     </tr>
     </c:forEach>
</table>The CusID and CusName are printed in one long column rather then having a table with two columns side by side as desired.
Could anyone show me a JSP code example which prints two ArrayLists in seperate columns of a HTML table?
many thanks in advance to anyone who replies,
James.

Lemme see if I understand correctly...
You have a grid object, with two ArrayLists, cusID and cusName. You want to print a table that looks like this:
|    cusID[0]    |    cusName[0]    |
|    cusID[1]    |    cusName[1]    |
//...My approach would be to redesign your grid to contain a single ArrayList of Customers, which would be a simple JavaBean, like this:
package beans;
private String id, name;
public class Customer implements java.io.Serializable
public Customer();
public void setId(String _id) { id = _id; }
public void setName(String _name) { name = _name; }
public String getId() { return id; }
public String getName() { return name; }
}Then change your grid to use the Customer bean to store customer IDs and Names in a single array list (named customers) with an appropriate get method... then you could do:
<table border="1">
     <c:forEach var="customer" items="${grid.customers}">
     <tr>
          <td><c:out value="${customer.id}" /></td>
          <td><c:out value="${customer.name}" /></td>
     </tr>
     </c:forEach>
</table>

JSTL nesting of foreach tag in the c:import

Ran into the problem when migrated the jstl to 1.2.
We have the code like below with the c:import and dynamic parameters.
jstl 1.2 is complaining about the nesting of tags.
<c:import url="Ixxxxxxxx">
<c:forEach var="entry" items="${usebean1.htmlParameters}">
<c:param name="${entry.key}" value="${entry.value}" />
</c:foreach>
</c:import>
What is suggested approach for the c:import with dynamic parameters?
Any suggestions/solutions will be appreciated.
Thank you,
-Sreeni.

Are you the one who commented out the code you're looking for ?//String desc = StringFactory.getString(attributes.getValue("desc"));You just have to modify you AttributeObject class to hold a new field : String description. And then, it's up to you to create a new constructor or a new setter method.
Btw, this is not a Swing related question.

JSTL forEach tag taking longer time than scriplets ???

Hi Gurus,
My STRUTS action class setsup a collection object [roughly 900 + records stored as java beans] to be displayed on my view [JSP]. The problem is, when I iterate over this collection in JSP using <c:forEach> tag, it takes around 4-5 minutes to build up the page.
I coded the same looping logic through java scriplets embedded within JSP and the processing came down to 1 minute. Should I assume that <c:forEach> tag will have a processing overhead over plain java code in JSP?
FYI, I checked the server generated SERVLET code under WORK directory of TOMCAT for this JSP with <c:forEach> tag and find lot of code being generated for this <c:forEach> tag implementation. Could it be that the processing of these generated code takes longer than plain java using scriplets?
Please Help.
Thanks,
Karthik.

Never looked at the speed issues. For me it has always been "fast enough"
When displaying pages with 900 records on it the common approach is to split the result across multiple pages, so that loading doesn't get too long.
The JSTL tags obviously introduce some overhead in extra procedure calling. As you found out by looking at the generated servlet code.
Also the EL expressions have to be evaluated. using the reflection APIs. Its pretty certain that direct access to the object is faster.
The forEach tag uses an iterator under the hood, where you are calling get(i) directly on an ArrayList.
Any or all of these would be contributing. My guess would be the EL expression evaluation is probably the most overhead.
One thing about your example I would like to see is how long it would take using an Iterator, rather than calling get(i) on the array elements. That would remove at least one of the differences.
So in short, yes the JSTL is adding overhead to your page. I'm a bit surprised to hear it is so much though.

ForEach items syntax help please

This shouldn't be a problem but it is. I have a JSP. I am sending it an attribute that is a collection by calling setAttribute() on the request and then dispatching to the JSP from my front controller servlet. I want to iterate through the collection. The name of the attribute is "changeRequets" and I have tried accessing it without any scope qualifiers and with scope qualifiers and no matter what, this forEach produces no data. I have verified that the JSP is receiving data, because I've accessed the request attribute separately without JSTL. What is wrong with the following please?
   <c:forEach var="chgRequest" items="${requestScope.request.changeRequests}">
                <tr>
                    <td>
                        <input type="radio" name="crButton" value="<c:out value="${chgRequest.crChangeRequestID}"/>" <c:if test="${status.first}">checked</c:if> />
                    </td>
                </tr>
</c:forEach>This produces no data, no rows. I don't get it. I can't find anything in my JSTL book that helps. Thanks.
Ken

Ignore the previous reply
change it to the following
<c:forEach var="chgRequest" items="${changeRequests}">
                <tr>
                    <td>
                        <input type="radio" name="crButton" value="<c:out value="${chgRequest.crChangeRequestID}"/>" <c:if test="${status.first}">checked</c:if> />
                    </td>
                </tr>
</c:forEach>

How to numberformat when using sql:query alogn with c:forEach JSTL tags

Is there anyway to format the numeric values returned from the database when using <sql:query> alogn with <c:forEach> tags
Here is my jsp code
<sql:query..../>
<c:forEach var="row" items="${queryResults.rows}">
<tr>
<td><c:out value="${row.COL1}" /></td>
<td><c:out value="${row.COL2}" /></td>
</tr>
</c:forEach>
Col1 values are numeric without any formats Eg: 1000, 10000, 1000000 etc.
how can i format them to 1,000 , 10,1000 , 100,000 etc

It is polite to mention what your answer was. These posts are not just here for you to ask questions, but to be used as a resource for other people to find answers. Saying "I solved it" with no details helps noone.
I presume you discovered the JSTL <fmt:formatNumber> tag?

[JDev 10.1.2] Compare JSTL var attribute with sessionScoped bean attribute

I'm new to JSTL.
I'm looking for a way in JDev 10.1.2 to compare a sessionScope bean attribute (sessionScope.User.Username) and a JSTL attribute variable. For this purpose I've developed the following code:
+<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c"%>+
+<%@ page import="bean.User"%>+
+<jsp:useBean id="User" class="bean.User" scope="session" />+
+...+
+<c:forEach var="Row" items="${bindings.ReadOnlyViewObject.rangeSet}">+
+<c:choose>+
+<c:when test="${Row.CreatedBy == sessionScope.User.Username}">+
+...+
+</c:when>+
+</c:choose>+
+</c:forEach>+
+...+
However it doesn't work on the test line. I'm not able to compare Row.CreatedBy to sessionScope.User.Username.
I've also tried <c:when test="${Row.CreatedBy == User.Username}"> without success.
Could you help me?
Thanks.

The bean property will have an initial lowercase name, so try sessionScope.User.username ?
I believe since you used the jsp:useBean, that you can also just use User.username without the "sessionScope" in there, as well.
