How to display rows of data in JSP?
Hi,
I am learning Servlet and JSP. There is an exercise which requires us to access a database from a Servlet and display the retrieved data in a JSP.
Now I am ok with the database connection. So how to display the data using some kind of loop?
Regards
They're called ResultSets and they are returned when you execute a query from a Statement. The next() method will tell you whether or not you have another row of data to read.

How to display rows of data into different columns?
I'm new to SQL and currently this is what I'm trying to do:
Display multiple rows of data into different columns within the same row
I have a table like this:
CREATE TABLE TRIPLEG(
T# NUMBER(10) NOT NULL,
LEG# NUMBER(2) NOT NULL,
DEPARTURE VARCHAR(30) NOT NULL,
DESTINATION VARCHAR(30) NOT NULL,
CONSTRAINT TRIPLEG_PKEY PRIMARY KEY (T#, LEG#),
CONSTRAINT TRIPLEG_UNIQUE UNIQUE(T#, DEPARTURE, DESTINATION),
CONSTRAINT TRIPLEG_FKEY1 FOREIGN KEY (T#) REFERENCES TRIP(T#) );
INSERT INTO TRIPLEG VALUES( 1, 1, 'Sydney', 'Melbourne');
INSERT INTO TRIPLEG VALUES( 1, 2, 'Melbourne', 'Adelaide');
The result should be something like this:
> T# | ORIGIN | DESTINATION1 | DESTINATION2
> 1 | SYDNEY | MELBORUNE | ADELAIDE
The query should include the `COUNT(T#) < 3` since I only need to display the records less than 3. How can I achieve the results that I want using relational views???
Thanks!!!T#
LEG#
DEPARTURE
DESTINATION
1
1
Sydney
Melbourne
1
2
Melbourne
Adelaide
1
3
Adelaide
India
1
4
India
Dubai
2
1
India
UAE
2
2
UAE
Germany
2
3
Germany
USA
On 11gr2, you may use this :
SELECT t#,
REGEXP_REPLACE (
LISTAGG (departure || '->' || destination, ' ')
WITHIN GROUP (ORDER BY t#, leg#),
'([^ ]+) \1+',
'\1')
FROM tripleg
where leg#<=3
GROUP BY t#;
Output:
1 Sydney->Melbourne->Adelaide->India
2 India->UAE->Germany->USA

How to display a pdf file in jsp
hi,
How to display a pdf file in jsp iam having a class which will return fileinputstream of the file object. the pdf file is in server.
regards
ArulA JSP is a combo of HTML and Java, so you can't really "display" a PDF file in a JSP.
You can provider a href link to the PDF file in your JSP.
You can use some utility package to read the contents of the PDF, pull certain things out of it, and display that in your JSP as html
In a servlet you can set the content type to application/pdf and write the binary data of the PDF back to the browser. Once the browser finishes reading in the data it should open the PDF. -

How to display planned movement date and actual movement date together?
Hi, Professionals,
My purpose is to list delayed outbound deliveries.
Anyone could tell me how to display planned movement date and actual movement date?
Appreciate your help.Thanks Shiva.
I tried another way to do it. It works only for a short period of time.
By using VL06O, I list all outbound deliveries by limiting both planned goods movement dates and actual goods movements dates to the same week I would like to inspect. Say both from 7th/11 to 14th/11.
then I list outbound delivery list with planned goods movement date to 7th/11 but left out actual goods movements dates this time.
In excel, I compare those two lists and filter out those unique ones because those unique documents means delayed deliveries which cannot delivery according to planned date.
However, the "delayed" list generated by this method has some noises. Not all of documents are really delayed although most of them do.
I'm also looking for a way to list sales documents number of these delayed delivery documents so i can retrieve order details from it such as order value.
Help still needed. -
Displaying metadata, how to display ONLY the Date
I would like to display the Date below each image in Aperture 3. When I select "Date" in the Browser & Viewer Metadata window, the result is a very long string with the Date, the Time and the Time Zone. meaning that most of the time I see nothing because the string is much too long to be displayed...
How to display ONLY the Date ?
Thank you.

I will do that but still... if the Date could be ONLY the Date "without time and time zone", I would be able to display more information.. and it will look nicer.
I said at the top of my first response above: +Afaik, there is no way within Aperture to change the date format of the date metadata overlay.+
Send Aperture feedback to Apple via "Aperture→Provide Aperture Feedback"
In the past I used Expression Media and the config for displaying such info was better.
Aperture has a strange interface for it (and for other parameters), it does not behave at all like an Apple software (for the GUI), probably an external development team... but I agree it is more complex than iPhoto.
Aperture is 10x more complex than iPhoto.
If you want to see a rigid, boxed, "engineer"-style image database interface, take a look at Lightroom 3. It's a great program -- but it's a very different concept of information presentation and interaction.
Thanks again. -

OBIEE:How to display row/columns where no data is present in pivot results?
I have a request from some team members to provide an OBIEE report of 7 teams and the number of open incidents for each team by week.
I was able to create the pivot listing the teams vertically and the age (by week#: 1 week, 2 weeks, 3 weeks, 4 weeks & > 4weeks) horizontally.
The dilemma I have is that of the 7 teams that have incidents tickets only 4 of them have data, thus only those 4 teams that have ticket data show up in my pivot. I would like to be able to reflect ALL 7 teams even if representing a dash or null value across the pivot for those teams that don't have data.
Does anyone know if this is possible and if so, how would I do this? I've tried searching the internet and found out how to replace a null value with a dash in columns/rows when a cell is null. But not how to display an entire row (or column) where no data is present.
Edited by: coutya on May 22, 2012 11:01 AM
Edited by: coutya on May 22, 2012 11:02 AMYou are correct; if there are no data at all, those teams won't show in a pivot table. NULLs or dashes only work if a particular column is null. There are two ways to accomplish what you wish. The first example I thought when I wasn't aware of being able to do a LEFT OUTER JOIN in Answers using the Advanced tab. The first method works nicely, though and is simpler to execute.
Read my solution here:
Re: Section Values showing NULL in Pivot
To do the LEFT OUTER JOIN read this:

How to display 2 dimensional data. i.e with rows and columns?
Hi,
I want to know how to display multiple, variable
rows and columns that are got from the database through
queries in forms.
(i,e. a Matrix of Values,something similar to an Excel Spreadsheet).
Is there a component in forms similar to JTABLE that is
available in Java through which MULTIPLE, VARIABLE
rows and columns can be displayed ?.
I am not using a base table since this data is got thru
a number of packages and procedures that are used in
Loops.
NOTE : I am using forms 6i.
Thanks
Sharath.I've heard Grant mention adding a Grid component to the Forms toolbox. From the context I would guess this is not yet even under development, so it's not going to be available anytime soon. And not for 6i.
Sorry, APC -
How to display Rows as Columns in JSF?
I am using dataTable component to get data for my Menu, i have one column in it which returns me the data, because its automatically adding <tr> and <td> tags to it, its showing data in tabular form.
I want to show output Horizontally instead of Vertically the way its showing.
Is their any way i can display Rows as Columns?
Code:
==============================================
<div class="bodyarea">
<div id="location">

<f:verbatim></li></f:verbatim>
</h:column>
<f:verbatim></ol></f:verbatim>
</h:dataTable>
</div>

Thank youTable is not the html element for you, in this situation.
I would use a dataList component (distributed with myfaces implementation).
dataList is able to return a list of item, and using css you will be able display in a horizontal grid. (otherwise you can use layout="grid" in dataList).
Anyway...my impression is that who made JSF was not really understanding how a html programmer like to write his code.
Why do JSF gives us only the possibility to write list of items throught tables?
Why do JSF prints error messages throught tables?
Why div is not a standard component?
This is an incredible lack...
I see also other incredible lasks...but they don't concern html ;) . -

JSP: How do display list of objects in jsp table?
sorry that my question my confuse you, let me explain more.
in my java class, have method : public List retrieveAllVacancies(); and it returns a list of available vacancies.
on my jsp page, i want to display the vicancies in the table have 3 rows:
vacancy title | location | contract type
should i use some form of for loop or iterator to get the vacancies in the list? how does the jsp page get the list of objects?
anyone can help me? thanksi found out the actual thing i look for is how to pass the vector to the jsp page.
<table>
<%
Vacancy vacancy= new Vacancy();
Vector allVacancies = new Vector();
*//allVacancies = (java.util.Vector)request.getAttribute("allVacancies");*
if(allVacancies.size() == 0)
out.print("<br><br><br> There are no vacancies available!!");
else
%>
<tr>
<td>Vacancy Title</td>
<td>Contract Type</td>
<td>Location</td>
</tr>
<%
for (int i=0;i<allVacancies.size();i++)
vacancy = (Vacancy)allVacancies.get(i);
%>
<tr>
<td><% out.print(vacancy.getVacancyTitle());%></td>
<td><% out.print(vacancy.getContractType());%></td>
<td><% out.print(vacancy.getVacancyLocation()); %></td>
</tr>
<%
%>
</table>*//allVacancies = (java.util.Vector)request.getAttribute("allVacancies");*
if i have this line, when i open the jsp page it will gives NullPoniterException.
the following was what i found for the similar problem,
You can add the Vector to the HttpSession with_
session.setAttribute(String name, Object value)_
or to the ServletRequest with_
request.setAttribute(String name, Object value)._
In the other JSP, retrieve the value with_
session.getAttribute(String name)_
or to the ServletRequest with_
request.getAttribute(String name)._
but i tried to do in this way it didn't work. for sure i didn't do it correctly. could anybody give bit more explanation about how to pass the Vector to the jsp page?
any help would be appreciated.
