Comparing date in jsp+jstl+el

I need help because i have to translate from jsp to jstl (using also Datetime Tag Library) but i can't . I have to do currentDate/HOur-Date/hour on DB. Logic the difference in millisec and then the division. But how can operate?
Operations are between ${...} but i can't use <dt:currentTime />, dt:format and other
Help

attributte value doesn't accept any expressionsWait, you said "the page underlines"?? So you're using an IDE? Are you sure that it a JSTL problem and not an IDE problem? Ignore the IDE and just execute the code. Does it work without any compilation errors or runtime exceptions? If so, then there's a problem in the IDE.

Grouping Data with JSP or JSTL

Hi All,
I would like to ask a question about how I can group data in JSP. Essentially, I have a DataBean (extends ArrayList) that is being returned to my JSP. The ArrayList contains HashTables. Please note that the JSP assumes the data is returned in sorted order. This JSP is not responsible for sorting the data itself.
[UPDATED EXAMPLE]
For example, here is what the data might look like:
Column A Column B Column C
1 2 3
1 15 20
4 5 6
4 99 66
7 8 9
10 11 12
Here is how I would use my DataBean:
String column1Name =bundle.getString(�columnA.title�);
String column2Name =bundle.getString("columnB.title");
String column3Name =bundle.getString("columnC.title");
/* Loop through the bean. */
for (int i=1;i<myDataBean.size();i++) {
Hashtable reportRow=myDataBean.get(i);
String column1Value=reportRow.get(Constants.COLUMNA);
String column2Value=reportRow.get(Constants.COLUMNB);
String column3Value=reportRow.get(Constants.COLUMNC);
}Question
If I want to change my layout/display to group by a particular column. How would I do that without changing the data structure that is running my current DataBean? Below is an example of grouping by the values in ColumnA.
ColumnA: 1
ColumnB ColumnC
2 3
15 20
ColumnA: 4
ColumnB ColumnC
5 6
99 66
ColumnA: 7
ColumnB ColumnC
8 9
ColumnA: 10
ColumnB ColumnC
11 12
Your help is very much appreciated.
Thanks!

Just curious, do people find my question unclear? Can I help clarify any points?

JSP/JSTL & XML

I am trying to have JSP pages parse and read an XML file and then return some data in an HTML table. I'm using the JSTL libraries and have a basic understanding of them, but I apparently need help.
My first page just gets the value and passes it to the second page. The second page handles all of the processing. Here is my JSP page:
<%@page contentType="text/html" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="x" uri="http://java.sun.com/jsp/jstl/xml" %>
<%@include file="index.jsp" %>
<% String clientID = request.getParameter("enteredID"); %>
<c:import url="npiXMLTest5.xml" var="doc" />
<x:parse varDom="dom" doc="${doc}"/>
<x:set var="srcCID" select="string($dom/npiNumbers/client/clientNum)" />
<html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>NPI XJTL Test</title></head>
<body>
<c:set var="CID" value="<%= clientID %>" />
<h2>NPI XJTL Test Page</h2>
<table border="1">
<tr><th>NPI Number</th><th>Description</th></tr>
<c:choose>
<c:when test="${CID}=${srcCID}">
<x:forEach select="$dom/npiNumbers/client/npiNum" var="$n">
<tr><td><x:out select="$n/npi" /></td><td><x:out select="$n/desc" /></td></tr>
</x:forEach>
</c:when>
<c:otherwise>
There is an error with your coding
</c:otherwise>
</c:choose>
</table></body></html>My XML structure is as follows:
<npiNumbers xsi:schemaLocation="http://localhost/namespace NPI_XSD5.xsd" xmlns="http://localhost/namespace" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<client>
<clientNum/>
<clientName/>
<npiNum>
<npi/>
<desc/>
</npiNum>
</client>
</npiNumbers>I am trying to return the results of the <npiNum> element (which can have multiple values) - <npi> and <desc> - in a table based on the <clientNum> element. I try to evaluate the page variable with the xml element. If it matches, I will return a table. A client can have multiple <npiNum> elements, so the construction of the table is in the x:forEach loop.
I think my problem is getting the variable from JSP to compare against the <clientNum> element in the XML file.
Any ideas?

I think your problem is less JSP/JSTL and more querying the XML.
You are trying to "select all <npinum> elements from a client based on clientnum"
I am far from an expert on XPath, but I think the following query is what you are after: "/npinumbers/client[clientNum=????]/npiNum"
To do that with JSTL you would replace ???? with $param:enteredId or $CID (equivalent in your example)
Here is the resulting JSP page.
<%@page contentType="text/html" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="x" uri="http://java.sun.com/jsp/jstl/xml" %>
<c:import url="npiXMLTest5.xml" var="doc" />
<x:parse varDom="dom" doc="${doc}"/>
<html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>NPI XJTL Test</title></head>
<body>
<c:set var="CID" value="${param.enteredId}" />
<h2>NPI XJTL Test Page</h2>
<table border="1">
<tr><th>NPI Number</th><th>Description</th></tr>
<x:forEach select="$dom/npiNumbers/client[clientNum=$CID]/npiNum" var="n">
<tr><td><x:out select="npi" /></td><td><x:out select="desc" /></td></tr>
</x:forEach>
</table>
<hr>
<form>
<input type="text" name="enteredId"/>
<input type="submit">
</form>
</body></html>I made up the following test file to use with it. I don't know if it was exactly what your requirements are, but it was a best guess based on your info.
<npiNumbers>
     <client>
          <clientNum>42</clientNum>
          <clientName>Ford Prefect</clientName>
          <npiNum>
               <npi>123</npi>
               <desc>life</desc>

For eg: The amount should be displayed in 0.00 format .when i am exporting it to excel it is displaying as 0 :( .
I am using the following code in JSP.
"out.print(amt + '\t');"
Would like to know if there is any otherway where in i can get my requirement.
Thanks
Tom

Hi,
Try using format part of the JSTL tag libs.
Syntax :
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<fmt:formatNumber value="40" pattern="$#,##0.00"/>
I need help in writing the data from JSP to excel.I
somehow able to retrieve the data into excelHow do u convert the jsp to excel?
One way to convert the jsp page to excel, is to render it as an excel appl instead of html. Set the content type of the response to application/ms-excel.
response.setContentType("application/ms-excel")Hope this Helps....

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.

Should I use JSP,JSTL,SERVLETs without a framework?

Hi Guys
I'm making a multi player browser game. The game will have some forms to setup data into the database and the player will be able to check other players data.
I will load the players data from the DB into a Bean when the application starts and then just get the other players information from DB when and if asked.
I'm planing on doing it as MVC2 using JSP, JSTL, SERVLETs, BEANs
Would you recommend me to use Struts for example? should I just use it without any framework?
I read a lot about Struts and can't really see what it can bring to an application like mine. I can use the i18n easily with JSTL and for few validation of forms I don't know if it's worth it.
What do you think? (-:
Thanks in advance
(-:

If your going to use MVC2 then I would use a framework, otherwise where are you going to get your MVC from, were you planning on writing an MVC yourself?

Comparing data in the database with the input text

hi there i have problem with the comparing data in the database with the input text. here is the piece of code of mine:
//declaration
datasourcedb.connect();
String stcode = req.getParameter("txtCode");
ResultSet rs = null;
String action = req.getParameter("action");
ResultSet portquery = null;
if (action.equals("SELL"))
-->portquery = datasourcedb.query("SELECT stockcode FROM portfolio where stockcode =\'"+ stcode + "\'");
-->portquery.next();
-->if((portquery.wasNull()) == true)
disp = req.getRequestDispatcher("error.jsp"); }
else */
Status = "Sell";
datasourcedb.close();
with the code that i marked with --> it doesnt work since i have to compare the input text stcode with stockcode in the db. could anyone tell me how to compare it?
regards
virginia

i have try to change into this code:
if (action.equals("SELL"))
portquery = datasourcedb.query("SELECT distinct stockcode FROM portfolio where stockcode =\'"+ stcode + "\' + and userName = \'"+ user + "\'");
if(portquery.next()) {
Status = "Sell";}
else {
disp = req.getRequestDispatcher("error.jsp");
but so far the coding doesnt give any result.... could anyone help me? since the coding does not reach status n the disp

Javax.servlet.jsp.jstl.sql.Result and arraylist

Hi,
I try to explain my problem, I have posted in another section of forum, but perhaps this is a better place:
I'm trying to use MVC model, so I call an EJB from a servlet which returns me a javax.servlet.jsp.jstl.sql.Result object (this derive from a resultset of a query) and then I make this available to a jsp page.
I've choosen to return an javax.servlet.jsp.jstl.sql.Result object because I'd like to use this syntax:
<c:forEach var="profiloString" items="${listaProfili}" >
${profiloString.anything}
</c:forEach>Now I need to put my listaProfili object in session and permit users of my application to add and delete items from it. Finally I will update my database with the new data from listaProfili object.
If listaProfili is an arraylist I can easily add or delete item from it, but if it is a javax.servlet.jsp.jstl.sql.Result I don't know how I can do this.
If I return an arraylist object instead of an javax.servlet.jsp.jstl.sql.Result object, I can't use "<c:forEach ..." syntax.
Can anyone help me?
Thanks.

So why didn't you think that the JSP forum here wasn't a good place to ask JSP questions like this one?
You can use <c:for-each> with a List. That's how it's designed. I don't understand why you say you can't. Perhaps you were confused by the SQL tags in JSTL. But anyway, you should just return a List from your EJB and forget about using obscure internal JSP classes.

Compare data in R/3 with data in a BW Cube after the daily delta loads

Hi Friends,
How can I compare data in R/3 with data in a BW Cube after the daily delta loads? Are there any standard procedures for checking them or matching the number of records?

Hi Sunil,
If you want to check the records daily instead of checking the data in R/3 manually ......
You can try this...
If you have staging DSO(level 1) that means whatever data is in source system load it to Staging DSO without any routines or any modifications.
Now load this DSO data to Cube or DSO(level 2) as per your requirement with routines etc.
Now Staging DSO contains Source system data.
Now the level 2 Cube or DSO contains BW data with some modifications.
Now create a Multiprovider based on level 1 and level 2 data targets.
Now create a report on which keyfigures you want to test the data.
In Multiprovider there is a field called 0infoprovider in data packet dimension.
you can drag this infoprovider to the columns and restict your keyfigures with level 1 and level 2 data targets.
In the first column you can see the level 1 DSO data ( source system data),in the 2nd column you can see the BW data.
Now create a formula which gives the diffrence b/n level 1 and level2.
that is R/3 data - BW data.
If the diffrence is zero both R/3 and BW data are same.
if the diffrence is not eqaul to zero check whether any routine is there or not.

Comparing data b/w biw and oltp

hi
Could some one can halp me how to compare data between biw and oltp system.which has been extracted.
Thank for your precious time spent to help me in learning.
Thanks,
Jagadeesh

Jagadish,
It is not always all extracted data are coming from one standard table and comparison is easy. most of the time from multiple tables. There are couple of things you can do.
1. If you know any R3 functionals you can inquire about reports available that produce the same kind of column groupings.
2. If no one exists or do not get much help from them, and if you have SQ01 access in R3 you can create a query to bring the same columns fromcorresponding tables (This is a harder because you need access and need to findout from where data is coming from though info is available in help.sap.com).
3. more practical would be select a small subset of data, with right filters in your selection columns of the info package and extract data, at the same time use the same selection in RSA3 (R3 side) to extract data and compare. This should tell you whether what you have in R3 is matching with the extracted data.
4. After your transformations you can compare the same with your info provider (cube or ODS) contents as well.
hope this helps,
Award points if useful.

Comparing data in different resultsets

Hi everybody!
I am working on an web application involving some EAI, as a requirement i need to compare data from two different sources (databases to be precise) and fill a XML based on certain rules. I wish to know if there is a way to compare two ResultSet objects (with almost similar data) directly, or the only way to do is compare each value seperately.
Also please suggest from efficiency point of view if its viable to store data from resultSet to a certain struc kind of object and then comparing, as it would involve lots of overhead compared to directly comparing the two resultsets.
TIA
Abhishek

i have to compare various columns of each row and assign flags in output xml as to note if data is inconsistant, though i am taking measures so as to get the rows in the same order in both result sets, but the primary purpose of this comparison is indeed to check data integrity between both the sources.

How to Hightlight the Data in Jsp Page

How to Hightlight the Data in Jsp Page,
I am doing doing search page,based on values given search page those are sent to servlet,in servlet based on some conditions if particuler id i am getting then i am redirecting to Respective jsp page with highlight the data from database..
Thanks in advance...

"Highlighting data in JSP sounds strange".
Without looking at your search specific algorithms I feel you are finally going to display a page (HTML content) to user which contains highlighted text. Highlighting is not directly related to server side language you use (JSP, ASP, PHP etc.). This is purely HTML and CSS. However, server side script (such as JSP) should generate HTML content for getting highlight effect.
Following HTML shows highlighted text using background-color property on span element.
<html>
<head>
    <title></title>
    <meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
</head>
<body>
      <p style="font-size:1.1em">This is a long paragraph which contains <span style="background-color: yellow;">highlighted text</span> and non highlighted text.</p>
</body>
</html>Thanks,

Table_comparison - how to compare data at a high level

Hi,
I have to do data validation at a high level between two tables that I am loading.
I am trying to use table_comparion transform but the problem is that my target table is at a much lower level than at which I want to compare data. So it has many more columns (both key and data fields) than what I want to compare.
Does the output of query transform ( which I am using as input into table_comparion) be in the exact same format as comparion table? If not, then can somebody suggest me something else.
Or how can I compare output of two query transforms ?
Thanks,
Saurabh Bansal

Dear Saurabh,
Not sure if you have already got the solution to this. If yes please close the thread.
If not, i would suggest you can use the validation rule to compare the two tables and then based on the PASS or FAIL result can check what needs to be done on the output.
Do post back if you have got the solution or you need any furthur help or else close the question.
regards,
Den

Compare data from a table

Hello, I am trying to compare data from one and the same table. In short I have:
     NAME     DTM     CHARGE
     Atanas     8/18/2012 9:33:23 AM     100
Atanas     8/18/2012 9:33:23 AM     101

     Joro     8/17/2012 12:10:21 PM 301
And I want to sum CHARGE for each DTM for each NAME and present the difference in an additional column, the output should be like that:
NAME     DTM     CHARGE DTM CHARGE DIFFERENCE
     Atanas     8/17/2012 9:33:23 AM     101 8/18/2012 9:33:23 AM 201 - 100

Joro     8/17/2012 9:33:23 AM     601 8/18/2012 9:33:23 AM 801 200
the DTM will be always /sysdate - 2/ and /sysdate - 1/,

I have some dates fields on JSP page I want to store data in mysql databse. Can someone tell me how I can format dates as I do for other data types in servlet before I send data to add in databse: such as
For int type data:
String paymentID = request.getParameter("PaymentID")
I format it like this for class Payment.
Payment newPayment(int.parseInt(paymentID)
how do i work with date fields this is what I Am trying to do:
Code patches....
import java.text.DateFormat;\import java.text.ParseException;
public date date1;
try
      date1= format.parse(paymentStartDate);
catch(ParseException pe)
System.out.println("Problem found");
....I do not get any error but it leaves date fields empty because date1 formatting never goes to try... Always say "Problem found on console"
Any help?

I just realized I should post the whole file... here is code of the servlet that recieved dates from JSP and process it.

                  try
