Displaying Mysql data in JSPs...

I am having problem displaying results that I am pulling from a Mysql table. When I test the code in a Java environment it works absolutely fine but when I transfer the code to a JSP it seems to execute it correctly but not display the output on the screen. The code I'm using is as follows.
<%
Class.forName("com.mysql.jdbc.Driver");
Connection conn=DriverManager.getConnection(url,"root","111101");
stmt = conn.createStatement();
rs = stmt.executeQuery("SELECT * FROM student");
while (rs.next()) {
System.out.println(rs.getString("student_id")+"<br>");
rs.close();
catch( Exception x ) {
x.printStackTrace();
%>
Any help on this topic would be much appreciated.

My code now reads like this but I am still ahving the same problem -> I can't display the data being retrieved.
<%@ page import="java.sql.*" %>

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.

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,

This may be your logic problem in the servlet.
I am expecting that you are doing like this.
On submitting the first select request....
In the servlet you setting the request.setAttribute("SUBJECT_CATEGORY_RESULT", ......
This is fine..
when you are submitting the second select request.
In the servlet you are setting the request.setAttribute("SUB_CAT_RES".... only.
But here you should set the request.setAttribute("SUBJECT_CATEGORY_RESULT", ... ALSO
Means both SUBJECT_CATEGORY_RESULT and SUB_CAT_RES should set in request.
Then it will work fine..

Featured Problem: Displaying unknown data in a GUI

The featured problems are problems submitted for your enjoyment and education. In the world of java, there are many many things to learn. It is, naturally, impossible to know them all. If you are new or old to java, this will give your brain a workout. The goal isto come up with the BEST solution to the problem.
Problem:
You need to show some data in a GUI List control. The difficulty is that the objects of data and their type will not be known to you until runtime. What is the best way to accomplish this?

You have a misunderstanding. You have NO CONTROL at all over the objects you are displaying. Reflection is the key, yes, but not on the object side. Instead on the cell renderer side.
The solution calls for the invention of a ListCellRenderer that allows the user of the render to render on whatever he wants, field or method result. The user tells you what he wants to render on and you render on it. Furhtermore if he can change the target and have your rendere adapt on the fly, that would be better.

Problem displaying XML data in XSL page

Hi There!
I'm having trouble when adding XML data from the schema (which shows up properly in the bindings panel) to the XSL page..
Following the step by step available here...
http://help.adobe.com/en_US/dreamweaver/cs/using/WScbb6b82af5544594822 510a94ae8d65-7a56a.html#ionCTAAnchor
After adding the XML item to the XSL file it ends up showing up as parent/client/name (no brackets) Instead of like the example above where it should display as {parent/client/name} and be highlighted. Also when previewing the XSL document it just shows 'parent/client/name' instead of the actuall XML content..
I believe the XML data source is properly attached because it shows up in the bindings panel.. But I don't know what else could be going wrong..
Any help would be great!

This is being enhanced to that the [...] button that appears in the data grid is available for all grid of data so that a popup with an extended area is shown.

Problem in displaying extension data at item level in JSP!!!

Hi Experts,
I am facing a problem when i try to display extension data in JSP. This is how i have coded in CRM system and in JSP:
After searching an order in the webshop let say order no 1, and i ll select this order no .1. Now the BADI CRM_ISA_BASKET_ITEMS is triggered and in the method getitems_getdata, i have written a code with hard coded values like this:
method IF_EX_CRM_ISA_BASKET_ITEMS~GETITEMS_GET_DATA..
data:wa_extension like line of ct_extension.
wa_extension-ref_guid = '498AB6EC7B623152E1000000AC1383C5'.(ref guid is item guid of the order 1)
wa_extension-name = 'Z_CustomItemExtData'.
wa_extension-value = 'he is a good boy'(hardcoded value) .
append wa_extension to ct_extension.
endmethod.
And in JSP i have written code like this to display:
<%-- code for extension data --%>
<tr>
<td class="identifier">Ext data</td>
<td class="value" ><%= JspUtil.encodeHtml(orderitem.getExtensionData("Z_CustomItemExtData")) %></td>
</tr>
But i am not getting the value in the JSP which i have hard coded in the BADI method. Is there any thing wrong in the above code? Please help me in this as i am very much new to ABAP.
Thanks a lot in Advance!!
Regards,
lakshman.

hi,
did you hardcode the ref-guid too? This could be the problem.

How to display the data in XML files into JSP using Jdeveloper.

Hi All,
I have two XML files one XML file has the view names and the other has the table names of a particular views, how to display the data in JSP using JDeveloper where when i click a particular view the list of tables of that particular view from XML file two should be displayed in JSP Page.
Are there any reference documents, regarding the above process please can anyone guide through how to do it.

Let the servlet ask your business tier to provide the data, then stuff it into beans, and pack those into the Session instance. Then forward the request to the JSP, let the JSP get those beans and display them.

DataGrid does not display XML data

Hello, and thanks for reading this...
I am having a problem displaying XMLList data in a DataGrid.
The data is coming from a Tree control, which is receiving it
from a database using HTTPService.
The data is a list of "Job Orders" from a MySQL database,
being formatted as XML by a PHP page.
If it would be helpful to see the actual XML, a sample is
here:
http://www.anaheimwib.com/_login/get_all_orders_test2.php
All is going well until I get to the DataGrid, which doesn't
display the data, although I know it is there as I can see it in
debug mode. I've checked the dataField property of the appropriate
DataGrid column, and it appears correct.
Following is a summary of the relevant code.
...An HTTPService named "get_all_job_orders" retrieves
records from a MySQL database via PHP...
...Results are formatted as E4X:
HTTPService resultFormat="e4x"
...An XMLListCollection's source property is set to the
returned E4X XML results:
...The "order" node is what is being used as the top-level of
the XML data.
<mx:XMLListCollection id="jobOrdersReviewXMLList"
source="{get_all_job_orders.lastResult.order}"/>
...The "jobOrdersReviewXMLList" collection is assigned to be
the dataProvider property of a Tree list, using the @name syntax to
display the nodes correctly, and a change event function is defined
to add the records to a DataGrid on a separate Component for
viewing the XML records:
<mx:Tree dataProvider="{jobOrdersReviewXMLList}"
labelField="@name"
change="jobPosForm.addTreePositionsToDG(event)"/>
...Here is the relevant "jobPosForm" code (the Job Positions
Form, a separate Component based on a Form) :
...A variable is declared:
[Bindable]
public var positionsArray:XMLList;
...The variable is initialized on CreationComplete event of
the Form:
positionsArray = new XMLList;
...The Tree's change event function is defined within the
"jobPosForm" Component.
...Clicking on a Tree node fires the Change event.
...This passes an event object to the function.
...This event object contains the XML from the selected Tree
node.
...The Tree node's XML data is passed into the positionsArray
XMLList.
...This array is the dataProvider for the DataGrid, as you
will see in the following block.
public function addTreePositionsToDG(event:Event):void{
this.positionsArray = selectedNode.positions.position;
...A datagrid has its dataProvider is bound to
positionsArray.
...(I will only show one column defined here for brevity.)
...This column has its dataField property set to "POS_TITLE",
a field in the returned XML record:
<mx:DataGrid width="100%" variableRowHeight="true"
height="75%" id="dgPositions"
dataProvider="{positionsArray}" editable="false">
<mx:columns>
<mx:DataGridColumn width="25" headerText="Position Title"
dataField="POS_TITLE"/>
</mx:columns>
</mx:DataGrid>
In debug mode, I can examine the datagrid's dataProvider
property, and see that the correct XML data from the Tree control
is present. However, The datagrid does not display the data in any
of its 6 columns.
Does anyone have any advice?
Thanks for your time.

Hello again,
I came up with a method of populating the DataGrid from the
selected Item of a Tree Control which displays complex XML data and
XML attributes. After the user clicks on a Tree branch, I call this
function:
public function addTreePositionsToDG(event:Event):void{
//Retrieve all "position" nodes from tree.
//Loop thru each Position.
//Add Position data to the positionsArray Array Collection.
//The DataGrid dataprovider is bound to this array, and will
be updated.
positionsArray = new ArrayCollection();
var selectedNode:Object=event.target.selectedItem;//Contains
entire branch.
for each (var position:XML in
selectedNode.positions.position){
var posArray:Array = new Array();
posArray.PK_POSITIONID = position.@PK_POSITIONID;
posArray.FK_ORDERID = position.@FK_ORDERID;
posArray.POS_TITLE = position.@POS_TITLE;
posArray.NUM_YOUTH = position.@NUM_YOUTH;
posArray.AGE_1617 = position.@AGE_1617;
posArray.AGE_1821 = position.@AGE_1821;
posArray.HOURS_WK = position.@HOURS_WK;
posArray.WAGE_RANGE_FROM = position.@WAGE_RANGE_FROM;
posArray.WAGE_RANGE_TO = position.@WAGE_RANGE_TO;
posArray.JOB_DESCR = position.@JOB_DESCR;
posArray.DES_SKILLS = position.@DES_SKILLS;
positionsArray.addItem(posArray);
So, I just had to manually go through the selected Tree node,
copy each XML attribute into a simple Array, then ADD this Array to
an ArrayCollection being used as the DataProvider for the DataGrid.
It's not elegant, but it works and I don't have to use a Label
Function, which was getting way too complicated. I still think that
Flex should have an easier way of doing this. There probably is an
easier way, but the Flex documentation doesn't provide an easy path
to it.
I want to thank you, Tracy, for the all the help. I checked
out the examples you have at www.cflex.net and they are very
helpful. I bookmarked the site and will be using it as a resource
from now on.
