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.

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>
 This is a long paragraph which contains highlighted text and non highlighted text.
</body>
</html>Thanks,

How to display all data on one page in web app

Hello.
So I have web app JSF (IceFaces framework) + JBoss all Crystal Report working perfectly. So I have page with Crystal Report tags (e.g.
<bocrv:reportPageViewer reportSource="#{crystalReport.reportPath}" ...
in this report I have table with some data (data from DB) and I want to display this data on one page. Unfortunately now this data are moving to the next page and unfortunately I even donu2019t know how switch to the next page (I see only info e.g. 1with 2).
So how to display this data on one page if its impossible how to torn on pagination.

So I canu2019t do this, I canu2019t display all data on one page (until Iu2019m using JSF tags)?
In JSF tags Iu2019m setting only path to file. In my bean Iu2019m using u201CReportClientDocumentu201D object itu2019s easy way to load report file (u201Copenu201D method) and set parameters (u201CgetDataDefController().getParameterFieldController()u201D method) and also connect to data base (u201Clogonu201D method) but I havenu2019t this property u201CsetSeparatePages(boolean)u201D.
Maybe Iu2019m doing this wrong and there is a simpler way maybe I can use somehow u201CCrystalReportVieweru201D please give my any advice.

Sensors in BPEL to publish data to JSP page ??

Hi Guys
In the BPEL console the result comes in a XML format. I want the result to be displayed on a JSP page that i created. So that the end user is comfortable to see results. I wanted to know can sensors be used to capture the results from the BPEL console and publish it on the JSP page. If we can do it, which kind of sensors will work. If you could provide me some examples on how i can do it .. It will be really helping . I am new to BPEL and need to complete it urgently. heLp required

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.

Display current date in jsp?

I hate asking for code, but I can't find anything on this. I'm trying to display the current date in the format YYYYMMDD on a jsp page without using scriplets. I've seen getting the time in milliseconds used through
<jsp:useBean id="now" class="java.util.GregorianCalendar" />
<c:out value="${now.timeInMillis}" />but now.year/Year/YEAR etc all give me 500 errors. I've also tried
<jsp:useBean id="now" class="java.util.Date" />
<c:out value="${now.year}" />But this just yields a constant. I know there is the SimpleDateFormat which I think would go with the java.util.Date example, but I'm not sure how it would be used in this context. Can anyone help me to get the date?

Or how about using the JSTL tag for it:
<jsp:useBean id="now" class="java.util.Date" />
<fmt:formatDate value="${now}"/>This tag leverages the java.text.SimpleDateFormat to do its job.
Cheers,

Display processing data ... page when gettting data

I need to display a page which will display processing data please wait .... till i get the data from the database. How do i implement this in jsp ??

Instead of going directly to JSP/servlet performing time consuming task, go to an intermediate JSP that has this code...
<%
String timeConsumingTask = "absolute URL to actual time consuming task";
%>
<META http-equiv="refresh" CONTENT="0; URL=<%= timeConsumingTask %>">
 please wait ....

Implementing Database codes FAIL /error in parsing data into jsp page

Hi there,
I have this problem trying to build a portal application. I am using the JSPDynPage, jsp page and a bean to build a page.
I have this problem parsing data from JSPDynPage to the beans and to the jsp page.
I tested out the connection between the beans and the jsp page. There is no error parsing information from the beans to the jsp page.
So i tried to test out the codes for the database from the beans.
Will this work? Because it does not display the results i want.
I need an Solution asap to find out wad is wrong also also the correct codes to the database.
public String db(){
try {
 InitialContext iC = new InitialContext();
 DataSource dataSource = (DataSource)iC.lookup("java:env/jdbc/mySQL");
 java.sql.Connection connection = dataSource.getConnection();
 PreparedStatement st = connection.prepareStatement("SELECT name FROM test WHERE id='123'");
 ResultSet resultSet = st.executeQuery();
 while (resultSet.next()){
 name = resultSet.getString("name");
 name = name.toString();
 connection.close();
 return name;
 } catch(Exception n){
 e = "Exception";
 return e;
This is the method i put in the beans to test out the database connection.

Displaying Mysql data in JSPs...

Problem with displaying BLOB images on JSP page using a servlet

hi. I have a big problem with displaying BLOB images using JSP. I have a servlet that connects to the oracle database, gets a BLOB image , reads it, and then displays it using a BinaryStream. The problem is , this works only when i directly call that servlet, that is http://localhost:8080/ImageServlet. It doesn't work when i try to use that servlet to display my image on my JSP page (my JSP page displays only a broken-image icon ) I tried several coding approaches with my servlet (used both Blob and BLOB objects), and they work just fine as long as i display images explicitly using only the servlet.
Here's what i use : ORACLE 10g XE , Eclipse 3.1.2, Tomcat 5.5.16 , JDK 1.5
here is one of my image servlet's working versions (the essential part of it) :
 BLOB blob=null;
 rset=st.executeQuery("SELECT * FROM IMAGES WHERE ID=1");
 while (rset.next())
 blob=((OracleResultSet)rset).getBLOB(2);
 response.reset();
 response.setContentType("image/jpeg");
 response.addHeader("Content-Disposition","filename=42.jpeg");
 ServletOutputStream ostr=response.getOutputStream();
 InputStream istr=blob.getBinaryStream(1L);
 int size=blob.getBufferSize();
 int len=-1;
 byte[] buff = new byte[size];
 while ((len=istr.read( buff ))!=-1 ) {
 ostr.write(buff,0,len);
 response.flushBuffer();
 ostr.close(); and my JSP page code :
<img src="/ImageServlet" border="0" > If you could just tell me what i'm doing wrong here , or if you could show me your own solutions to that problem , i would be very greatful ,cos i'm realy stuck here , and i'm rather pressed for time too. Hope someone can help.

I turns out that it wasn't that big of a problem after all. All i had to do was to take the above code and place it into another JSP page instead of into a servlet like i did before. Then i just used that page as a source for my IMG tag in my first JSP. It works perfectly well. Why this doesn't work for servlets i still don't know, but it's not a problem form me anymore . Ofcourse if someone knows the answer , go ahead and write. I would still appriceatte it.
here's the magic tag : <img src="ImageJSP.jsp" border="0" > enjoy : )

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"
