JSP / JSTL :: Display Data From One Or More Table - Left Navigation Page
Dec 14, 2012
I am new to JSP . I am Using Jdeveloper UDI to create JSP Pages.
My main idea in creating JSP to display data from one or more tables.
I created 2 pages called Serverpage.jsp and Messagecount.jsp and it is working fine as expected,
Now i want to create home page and it should also have left navigation menu and it should contain MessageCount and MessageStatus.
When i click on Messagecount or MessageStatus my home page should refresh and have to display new JSP page (MessageCount.jsp or Serverpage.jsp)
Here is my JSP pages
Serverpage.jsp
<%@ page contentType="text/html;charset=windows-1252" isELIgnored="true"%>
<!--<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>-->
<html>
<head>
<title>Welcome to Monitoring Page!</title>
<link type="text/css" rel="stylesheet" href="jdeveloper.css"/>
<script language="javascript" type="text/javascript" src="Calender.js">
[Code] ....

I am new to JSTL and JSP & I am running 2 seperate SQL queries from a java/jsp program and I need to display the results from both queries on one JSP page output.Currently I have java code that passes the 2 queries to a method along with passing the jsp files to output the query results
- the method dispatches the results to these 2 JSP pages using JSTL tags in hope for separate output results:
I need to have a way to display these 2 outputs into 1 jsp page: - currently one just overwrites the other.I also tried using the jstl core <c: tags in 2 separate methods on the same jsp page but the <c: tags just resulted in overwriting one another - The queries run and display fine except I cannot get them both to display correctly.using jstl and jsp for displaying multiple queries on the same page.example: the jsp file that runs the queries:
runQuery.jsp:
<%
String query1 = "SELECT * FROM TABLE A";
String query2 = "SELECT * FROM TABLE B";
runReport(query1...,viewResults1.jsp)
runReport(query2...,viewResults2.jsp)
%>
[code]....

I am relatively new to JSF. I am trying to display data into a web page sorta like a jTextArea or at least onto a panel that is on the webpage, something similar to that. I can display the data in a particular format but it won't appear onto a panel in a specific location or the panel being a particular size.

<sql:query dataSource="${statistics}" var="result4">
SELECT COUNT(id) AS count FROM statistics;
</sql:query>
<c:forEach var="row" items="${result4.rows}">
Total players: ${result4.count}
</c:forEach>
But, it doesn't work.

I need to pass advanced object into controller from JSP page, but I always get null result.It's a controller method:
Java Code:
@RequestMapping(value="admin-user-edit", method=RequestMethod.POST)
public ModelAndView editUser(@ModelAttribute(value="user") UsersEntity user)
{
if (null == user)System.out.println("User is null");
else
System.out.println("User name = " + user.getName() + " | Users id = " + user.getId());
ModelAndView view = new ModelAndView();
return view;
} mh_sh_highlight_all('java');
And this is a JSP page snippet. I need to choose some user from user list and pass it to controller.
XML Code:
<c:forEach var="user" items="${user_list}">
<tr>
<td><c:out value="${user.id}" /></td>
<td><c:out value="${user.name}" /></td>
<td><c:out value="${user.login}" /></td>
<td><c:out value="${user.status}" /></td>
[code]...
I tried to pass it through HttpServletRequest argument but all the same.

we had a requirement to display a combobox which is filled with some values on the webpage when somebody checks the checkbox which is present on the webpage.
The approach we have taken is ajax. how we did this is, when somebody checks the checkbox on the webpage we are initiating the ajax call requesting a servlet. this servlet pulls the data from the database, places the data in the request and forwards the request to a jsp. In that jsp i am writing simple html combobox and populating the values in the combobox from the request using JSTL and this jsp will be sent as response to ajax call. The ajax gets the html as responce which contains a combobox and i am just placing that html ( the complete response) in a div which is next to checkbox.
In this approach there is lot of pain. if i have to display 10 html components dynamically based on some condition then i have to have 10 jsp's one for each component. I always feel this is a wrong way of doing things. what is the best approach to deal with the dynamic stuff on webpages.

Is there a way to inform the Entity Manager or force the JPA provider to reload data from the database? The scenario could be data being updated by a store procedure or direct SQLPlus maintenance, without restarting the Application Server, the JPA need to load the newly updated data from the database.
I think the current JPA API is not enough. The void refresh(java.lang.Object entity) from EntityManager need to pass in the Entity object, I will like to know how to refresh the entire JPA Entity data after the physical table data being update from backend.

I have a program which consist of several classes. The program reads a pom file and parses the data and then writes the data to a static table. The issue I'm having is with writing my LIB file data to my table. In the HtmlDataTable Class Im trying to write the files that are read in the lib directory to the table. My table currently consist of 3 columns (missing jar files,Lib Directory files, and POM file data) currently Im only able to write the missing jar files data to my table. In the HtmlDataTable class there is a for statement where I write the missing jar file data to my table. Im also trying to write the contents of the Lib directory within this statement as well. This is where I'm having my issue. My other classes consist of a SAX parser which parses the xml file, a class that creates my static table and a class that compares the jar files in my lib directory to the jar files in my pom file. . Theres a lot of code so I included the parts I felt were useful. If needed I can include the other classes as well.
public class ReadPomFile extends DefaultHandler {
public static void main(String[] args) {
try {
// obtain a SAX based parser to parse XML document

I am creating a JSP page with a html table to display employee directory. This is scriptlet :
<%
List<Employee> list = new ArrayList<Employee>();
PhoneListController controller = new PhoneListController();
list = controller.getAllContacts();
for (Employee eachEmp : list) {
%>
and then i display the table rows and columns for each employee object(PS: I know scriptlets are bad and obsolete but this is my first individual project.)
I would like to change the background color of certain rows based on value of one particular value(based on eachEmp.getManagerCode).
How can i achieve that by using javascript? I tried to call a js function by calling onload event on . But as I need to check for each row that is not the possible solution. I have not tried jquery yet as I am very new to jquery and I didnt quite understand how to do it in jquery.

I'm new to JSP but I've to use it to grab data coming from an external site, pass data to a Bean, write data in a DB and redirect the user to another page. Follow the JSP page.
<%@page import="EJB.getResponse"%>
<%
long paymentID = Long.parseLong(request.getParameter("paymentid"));
String responsecode = "9999";
getResponse g = new getResponse();
[Code] ....
This is the bean:
@ManagedBean
@RequestScoped
public class getResponse implements Serializable {
private Long paymentId;
private String result;
private String auth;
[Code] ....
On the console I see the prints but I receive the NullPointerException
