Date in jsp

Hi all,
I have a typical problem
our application deals with getting reports from the database.
the user can enter the status code to get the details or can enter
to date and from date to get the reports .
only one is enough to get the reports ..both are not mandatory.
so if the user enters the statsucode the date fields can be kept empty.
by the function in java with interacts with database has a signature like
function(statuscode,todate,from date)
hence if we enter only status code the todate and from date are passed as
null ..hence we get an error
like null pointer exception....................
can u plz suggest me a solution

Well, you could simply check if the date values being passed are null and if yes, then use your default dates.

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,

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....

Dates in JSP page

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?

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?

Sending binary data from JSP (1.1)

Hi all:
I am using Tomcat 3.2.1 and Apache under Linux Mandrake OS.
I have a JSP (1.1) sending binary data (GIF, PDF, DOC ..) using response.getOutputStream().write(data)
method.
The problem is the precompiler automatically creates the JspWriter and puts some out.write("\r\n") lines
before I use getOutputStream method. The JVM throws an IllegalStateException because I am using both
methods (this is from Servlet 2.2 specification).
Must I change my code to forwarding to a servlet that make this work or is there a simple solution to
avoid this?
Thanks in advance.

Inserting data from jsp form to multiple tables !

Hi,
I want to insert data from jsp form to two tables
tables are
(1) Form
formId (PK)
deptName
(2) Data
formId (FK)
sNo
description
itemCode
and the problem is that i want to save information form a jsp form to above two tables and i have only one form.
so how do i insert data from a jsp form to multiple tables.

You already know what your form in the jsp will be and what fields they are. You also already know what your database looks like. Using one form, you should be able to break the data down, and give it certain ids and/or names, so that when the form is submitted, you retrieve the correct values corresponding to a specific field and insert it.
Unless there is something else I am not catching, this seems pretty straight forward.

Passing data from JSP to Oracle Reports

Hi,
We have a requirement to query and display data in JSP pages and when clicked on 'Report' button of the JSP, an Oracle report should be called.
The data which is queried in JSP should be passed to the Oracle report. Is there any way of doing it? This is to avoid re-querying the database again from Oracle Reports.
Environment: jdk1.3, Oracle Application Server 9i, Oracle 9i, Report 6i
Thanks in Advance,
Srinivas

You could have the Applet make a request to the server (via URLConnection).

Displaying calculated data in JSP pages

This is a general question about displaying data in JSP pages which has been calculated through ViewObj Routines. I have exposed the methods to the application level however, I want these methods to automatically run on the launch of the page. I can so this with a data action in the struts file. However, I have lots of these methods (all bringing single values of data), it seems inelegant to have 10 data actions or so. What's the best way to expose and show data on a JSP page automatically which has been calculated from the database rows.
Thanks in advance

You could convert the vo row to a hash using BeanUtils and then you could do what you want with it programmaticaly to automatically dissplay the lhash values.

Binary Data and JSP

Hi all I have a basic doubt. How does Servlets is preferred technology to generate binary data than JSP? Any limitation in JSP?

Okay,
When you write a JSP file, you type it in text, and all the text you type is sent to the client that requests your page. Everything is sent including carriage returns, spaces, tab characters and anything you have type into the file. Only things that are inside <% and %> do not get sent through. If you have several blank lines at the end of the file they will be sent to the client and may cause issues if you are writing binary data that needs to be handled by an application.
With Servlets you have to write data to the outputstream you get from the (cant quite remember) response.getOutputStream() method. This ensures that only what you want to send gets sent to the client.
It sepends on what you need it for. If it doesnt matter what you send through then JSP can be used to write binary data. In one application I had to send through sound files to the client and any extra data would only corrupt the sound, so it had to be sent using servlets.
Does that help?

HI Prabhat,
Thanx for your reply, I worked out and able to receive the data in oracle database, Actually there was some problem in insert Query. Now I have tested the same... and able to edit the same in the Database.....
But I am facing a new problem, Http Dispatcher in SES console is displaying all the Events generated as well as event in Que but there is no events in the Event Send. I guess it is not able to send the events.....?????
Event statical is showing like this
Events Received: 0 (0.00/sec)
Events Generated: 311 (0.19/sec)
Events Sent: 2 (0.19/sec)
Queued Events: 309 (0.19/sec)
Kindly suggest where is the problem, Is it a JSP problem or OSES end problem.....
Thanks and regards

How to sort the data in JSP using stylesheet sorting?

Hi, i extracted data out in and display them <%=data%> in the jsp, but how to sort? do i have to provide a drop down list that gives different sorting options, and when user clicks on one option, say sort by title, the collection of results are sorted out on the same jsp page? so all in all, only one jsp page is needed or do i need to create xml files, etc?
i have no idea how to integrate the xml sorting into the jsp page, even after seeing online help, cos there is no example of a jsp page with sorting to refer to. PLease help, thanks alot!

im getting the data from beans, but one of the requirements was that i cant use the database to sort and display but i have to use xslt to do the sorting in the jsps, so i have no idea how to do so. possible to give an example? thanks

No data in JSP Page

Hi,
JDeveloper: 10.1.3.3.0.4157
Database: Oracle XE 10.2.0.1.0
Browser: Firefox 2.0.0.14
I am doing the following steps but the resulting web page displays no data. Any
help would be appreciated:
- This is all in JDeveloper...
- Create an application, 'testapp', using the template [JSP, Struts, ADF BC].
- On the Model node, create a Business Components Diagram. Rename this to
'Business Domain Diagram' and put it in the 'testapp.model.businessdomain'
package.
- Go to a databse connection, expand Tables and drag a table,
'SYSTEM_PARAMETERS' on to the diagram. The table has 2 VARCAHR2(100) columns,
one of which is the primary key. I choose 'Business Component Entity Objects'
from the 'Create From Database Object' popup.
- I then right-click on the diagram and select 'Generate/Default Data Model
Components for Diagram'.
- I put the objects in the package 'testapp.model.datamodel' and create a new
application module; 'TestModule'.
- On the testapp.model.datamodel node, I create another Business Components
Diagram; 'Data Model Diagram' and, from the same node, drag
SystemParametersView and TestModule on to this new diagram.
- I then right-click TestModule and select 'Test', and the Business Components
Browser pops up allowing me to navigate through the dozen or so rows in the
table.
Right now I know that the database connection is all good and my java objects
can see then.
- I right-click on the ViewController node and select 'Open Struts Page Flow'.
From the Components pallet, I drag a 'Data Page' icon on to the
struts-config.xml diagram and rename it 'TestPage'.
- I then double-click this icon and accept all the default settings to create
the page and open it in the page diagrammer.
- From the 'Data Connection' pallet, I expand TestModuleDataControl' and drag
SystemParametersView1 on to the page.
- From the drag options, I choose 'Forms/Read-Only Form' and a form
containing a table is created. The table is 2x2 and contains bindings for
the databae table column names and data.
Now the naughty bit...
- I click the 'Run' icon, a new tab opens up on Firefox and the page renders -
i.e. I get a 2x2 HTML Table - but there is no data in it. I can see neither
the column name labels or the contents of the row. There being no text in
the table, it has collapsed to 2 very thin rows. I think that I should see
data from one of the rows in the table and I appreciate that I can't see
any others because I have not yet added any navigation.
I would appreciate it if anyone could point at the fatal flaw in this
procedure.

Hi,
make sure the Struts action in the Struts diagrammer is selected when pressing the run button. Or select the action and choose run from the context menu
