JSP :: JSTL Tag To Select Dropdown Value
Mar 14, 2014
I have for values in drop down:
<SELECT name = "productCodeDefault" id="productCodeDefault" value="<c:out value ='${ProductDefBean.productCodeDefault}'/>" >
<OPTION value="" ></OPTION>
<OPTION value="a" >A1</OPTION>
<OPTION value="b" >B1</OPTION>
<OPTION value="c" >C1</OPTION>
<OPTION value="d" >D1</OPTION>
</SELECT>
When I am getting value = "a" from ProductDefBean, In the dropdown 'A1' should get selected. This is not happening. What I need to modify?
Note** When I am doing view Source of my JSP, I am getting value='a'

I am familiar with Java but new to JSP. I have a Java Servlet app where user actions are recorded in a SQL Server database amd I now need to quickly put together a JSP front end application to view user actions. I want two drop down boxes to filter the results that will be displayed in a list box. What I need is the first drop down list box to show unique user names that have logged in. I can interrogate the database with the following SQL;
"SELECT DISTINCT(USER_ID) FROM AUDIT_MESSAGE"
Then when a user is selected from the first drop down list box (perhaps some sort of on change event) a second drop down list box shows the logins times of the selected user. Again I can interrogate the database with the following SQL;
SELECT SESSION_ID, EventTIME FROM dbo.AUDIT_MESSAGE
WHERE OPERATION = 'loginResponse' AND RESULTS = 'OK'
AND USER_ID = 'firstdropdownlistselection'
Then finally when a login time is selected in the second drop down list box all events for the selected user while logged in with that login time are displayed in the list box.

I am able to generate text boxes. But I need one specific thing in that:
Through a drop-down I should select a number and those many text boxes should get generated.
Suppose I selected 4 from the drop down list. Then on screen it should display:
Student 1: Textbox
Student2: Textbox
Student3: Textbox
Student4: Textbox

I have a jsf form which has a drop down. When I select any value in drop down it shows related details. When I use chrome browser, and I press back space key it comes back to the page, it keeps the value selected which was selected earlier, but in the firefox, IE it keeps the zero index selected. The same code is not working for chrome browser.
I would like the zero index to be selected in the drop down in previous page in chrome browser also when back space key is pressed...

I have a fixed list of 20+ values to be populated in a dropdown. The set of values are always going to remain the same, no future scope of modifications, additions or deletions.
Listing each of them as <option> in JSP is making the page look cluttered. Or is it better reading it as a comma-separated string from a properties file and then iterating to populate the dropdown.
What will be the best approach to populate such a dropdown in JSP?

Is it possible to get the list/ values in html/jsp from servlet?
I have a table inside an html/jsp page and when the user clicks a button I need to refresh the whole page with some additional text message.
Currently what I am doing is that I am using a java bean for the jsp page that contains a list of values inside the table then store it in session but I think there is a better way without storing it in session.
I tried using request.getParameter() but it only returns string.

I have list of employees in my database and their associated information like employeeId,supervisor and process. I have class named EmployeeDetails having same properties. I am fetching details of all users using below code:
<%EmployeeDetails employeeList;
employeeList=(List<EmployeeDetails>)assetmain2.getEmployeeList(loginName);%>
<table>
<tr>
<td>
Requested For <select name="requestedForName" id="requestedForNameID">
<option selected="selected">--Select--</option>
<%int i=0;
[Code] .....
In employeeList, we have list of objects having data of employees. I donot know how to get which object is selected in dropdown and based on that rest of the text fields are populated. Example:
Name ID Supervisor
-------------------------------------------------------
Pawan Kumar3033045Vimal Kumar
Vimal Kumar3040901Dinesh Hemrajani
If Pawan Kumar is selected from dropdown then '3033045' and 'Vimal Kumar' should get populated.

I have encountered a very tricky spot in a project that i am working on. I must have a JTable to programmatically select the very last row in an AbstractTableModel. I have tried every thing but nothing works so far.
The problem is is that the JTable only scrolls down to the second last table row in the model? What am i missing?
//Show the very last row in a tablemodel object using the method updateTableRows
//after an "insert action event" occurred
public void updateViewMode(String name,
java.util.List<NetworkSwitch> list,
boolean flag) {
CableTableModel model = cableTable.getCableModel();
[code]....
What happens is that the only row that gets selected is the second last row of the total rows iny AbstractTableModel object, "CableTableModel"
What am i missing?

What I need to do is ask the user to input some text and then turn it into pig latin. I am confused on how to select each word from the string to determine if it ends in a way or ay. I am to assume that the letters are all lowercase and the text ends with a period.
import java.util.Scanner;
public class Trial
{
public static void main(String [ ] args)
{
Scanner input = new Scanner(System.in);

I have problem with manually (through my java code) selecting items in a JTree. I did Google the problem and found solutions here :
[URL]
This code worked for me only partially. Once I tried selecting deeper nested nodes, I ran into problems. Since my production code is very cluttered I built an example and reproduced my exact problem in it.
DummyView.java
package de.fortis.tcws.client.controller;
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
[code].....
The important method is 'manualSelect(String[])'.
It streps through the tree by comparing user objects and finds the target node. Then it calls 'navigateToNode()' which uses the solution discussed in the links above.
This method behaves incosistently:
If you call it with an empty array it will correctly select the root node. The righthand pane shows the text of the selected node. = correct
If you call it with target node 1 it will correctly select node 1. The righthand pane shows the text of the selected node. = correct
If you call it with target node 1.1 it will select node 1.1 but for some reason it is not displayed as marked (no background). The righthand pane shows the text of the selected node. = only partly correct
If you call it with target node A it will run into an exception. Debugging reveals that the selection occurs correclty at first. You can also observe the righthand pane showing that 'A' was selected. But afterwards another TreeselectionEvent is occuring that has a NewLeadSelectionPath of null. I do not know where this second SelectionEvent is triggered from.
This code is run with Java 1.6.0_39 which is also what I will have to use in production.

I am quite new to Java programming. I'm actually taking a class and I have an assignment due tonight. The program below compiles and functions correctly for the most part. It is supposed to be a simple GUI Text Editor with Edit and Format functions. Of the functions under the "Edit" menu, only word count actually works. Cut, copy, paste, delete, and select all are not working.

I have a jsp form that has a drop down option for a user to select. I would like to know how to have a pre-selected option that has been retrieved from my database or provide a default option if none has been selected by the user. My form allows a user to update a record in my database and what I need to achieve is when a user is updating an existing record they do not have to touch the drop down box if the do not need to change that option.
Here is my current form below form method
="POST" action='UserController?action=edit&albumId=${album.albumId}' name="frmAddAlbum">
<label for="album id">Format : </label>
<select name="action" selected=<c:out value="${album.format}" /> >
<option value="listUser">CD</option>
<option value="listUser">Tape</option>
<option value="listUser">MP3</option>
<option value="listUser">VINYL</option>
</select>

I am struggling to get a way to click within a Pane and select a Line. The Line has been drawn by the user and there can be numerous.
For example if you select a Vertex I can just ask if it contains the point. How would you do this for a line?

Example of my table.Head1Head2 Head3Head4 ( table headers )
“R1C1”“R1C1”“R1C1”“R1C1”
“R2C1”“R2C1”“R2C1”“R2C1”
“R3C1”“R3C1”“R3C1”“R3C1”
Below is a snippet from DataTable component to display the contents of the “Head4” column.
<p:column headerText="Head4" style="width:150px;height:8px" >
<h:outputText value="#{message.data}" />
</p:column>
All the entries in the table are of type String.However, the String content for the “Head4” column can be very larger and displaying this makes the table very large.As an alternative, is there a way to provide a button for the “Head4” for each row and when the user selects the button on that row, the corresponding “Head4” column contents is displayed in a pop up dialog box ? I am using Primefaces 5.0.
