JSF :: Display Values Of Selected Checkboxes On Page After Submitting Form

Feb 13, 2014

I have the following simple "selectManyCheckbox" specified in my jsf page:-

<h:selectManyCheckbox id="animalsmc" layout="pageDirection" value="#{animalSelectionBean.selectedAnimals}">
<f:selectItem itemValue="1" itemLabel="Lion"/>
<f:selectItem itemValue="2" itemLabel="Tiger"/>
<f:selectItem itemValue="3" itemLabel="Elephant"/>
<f:selectItem itemValue="4" itemLabel="Eagle"/>
<f:selectItem itemValue="5" itemLabel="kangaroo"/>
</h:selectManyCheckbox>

I have the following specified in my bean class:-

private int [] selectedAnimals;
...
public int[] getSelectedAnimals() {
return selectedAnimals;
}
public void setSelectedAnimals(int[] selectedAnimals) {
this.selectedAnimals = selectedAnimals;
}

I would like to know how to display the values of selected checkboxes on the JSF page after submitting the form? I tried outputtext, however it displays the object and not the values. I cannot even frame the outputformat for the same.

JSF :: How To Convert Hashmap Values To Arraylist To Display On Page

Apr 2, 2015

I need assigning the selected hashmap values into a list and to display the values in a jsf page. The user will select certificates and will be stored in the below list:

private List<String> selectedCertificates = new ArrayList<String>();

The selectedCertificates will have the values ("AA","BB"). Now I will be passing the list into a hashmap in order to get the names and to display them on the jsf page.

My code is below:

Map<String, String> CertificatesNames =
new HashMap<String,String>(selectedCertificates.size());
CertificatesNames.put("AA", "Certificate A");
CertificatesNames.put("BB", "Certificate B");
CertificatesNames.put("CC", "Certificate C");
for(String key1: selectedCertificates) {
System.out.println(CertificatesNames.get(key1));
}

I want to display in my jsf page :

Certificate A
Certificate B

Now my issue is that is how to display all the values of the CertificatesNames.get(key1) in the jsf page as I tried to do the below and it printed all the values when I used the #{mybean.beans} using the :

List beans =
new ArrayList(CertificatesNames.values());

So how to do this?

EJB / EE :: Maintaining Values From Primefaces Form After Form Submit

Jan 29, 2015

I have a form containing several fields, 2 of which persist to different table in a database than the rest of the fields on the form. I have no problem persisting the data into both tables of the database, and after the form is submitted I reset the form to its default values. That all works fine.

But in the same session, when I open another form (a search form) and enter search criteria, which then displays a datatable containing the search results, those 2 values that are persisted to another table are not showing up, but the rest of the data is.

Here is the method that calls the persist methods:

@ManagedBean(name = "foreignPartyController")
@SessionScoped
public class ForeignPartyController implements Serializable {
...
public void saveData() {

[Code].....

The values do show up, but the problem is, when a subsequent form is opened in the same session (e.g. a search form) the field for that value shows the actual value, instead of the field being blank.'

I am not sure why the data from the one database ("parent") is showing up, yet the data from the other database ("child") is not.

Is it something I am doing wrong? I thought by setting the setter in the child controller class back to a new instance of the Entity class (PolicyPayment) that it would reset the form to default values, but at the same time retain (or save) the inputted values in the same session.

How To Visualize Values Of The Selected Row

Nov 30, 2014

I'm currently writing a small program, where I need to save data into a Defaulttablemodel in a jTable.I have to save the name, a number and the email-adress.I added a button which opens a new JFrame and there I need to change the email and/or the name.My current solution is far from good: No matter which row I select, i can only update the "newest" row (last created). How can I visualize the values of the selected row (out.println// or whatever) so I can go further and overwrite these values.My Code when I click on Update:

int zeilenwahl = jTableStudenttab.getSelectedRow();
// System.out.println(jTableStudenttab.getSelectedRow());
if (zeilenwahl != -1) {
this.setVisible(false);
new Bearbeitung().setVisible(true);
} else {
JOptionPane.showMessageDialog(rootPane, "Zum Bearbeiten Zeile auswählen");
}

Here is where the mistake is (probably)

public Bearbeitung() {

initComponents();
jTextFieldvorname.setText(Student.vorname);
jTextFieldnachname.setText(Student.nachname);
matrikelstring = matrikelstring.valueOf(Student.matrikelnummer);
jLabelmatrikelwert.setText(matrikelstring);
jTextFieldemail.setText(Student.email);

}

JSF :: Reset Values In Back Form Bean

Jun 3, 2014

When we have a jsf form to store clients in a ddbb for example and the backing bean is in session scope.... Lets think of a user that requests 3 times the xhtml view with the form to store 3 clients.

1) If we dont reset the backing bean each time the form is processed, he would see the values he sent beforea and it doesnt have much sense, right?

2) Here there is an example of clearing form after submitting : [URL] ...... Clearing the form after submititng is a common practice for the reason of the statement 1, right?

3 ) What is the best or normal approach to reset values in a form? when the user requests it or done automatically by the application after processing a form?

4) Are there known issues about resetting or not resetting the values in a form bean?

JSP :: Java Code To Display Data In The Form Of Map

Apr 8, 2014

I written java code in JSP to display data. I know it is bad practice. Actually my Business-service communicates with DB and returning data in the form of MAP. I don't have beans Because the fields in DB is dynamically changing. So, for now I'm retrieving Data by writing Java code in JSP. Is there any other way to display data without writing java code in JSP?

Java Servlet :: How To Receive Parameters From A Form And Insert Values In DB

May 23, 2012

I'm trying to create a Servlet that takes input from a form and process it and insert it in database.tablename.

My MAIN ISSUE IS WITH THE NUMBER OF COLUMNS THAT WOULD BE DYNAMIC AND THUS CANT RECEIVE THE PARAMETERS IN STATIC CODE.

Here is the form code

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<form action="Test" method="post" />
<table width="90%" border="1" cellspacing="1" cellpadding="1">

[Code] ....

And here is the Servlet

import javax.servlet.*;
import javax.servlet.http.*;
import java.sql.*;
import java.io.*;
public class Test extends HttpServlet {

[Code] ....

This is the basic code structure and I'm trying to figure out this special case with handling the multiple parameters:

I don't want to use String []a=request.getParameterValues("studentname"); as hard code. The reason being the number of rows will be diyamic and I would like to get the column name and then then use an array of string to take values. But how can I connect these to form a query so that the rows goes on inserted one after other.

JSP :: How To Display Multiple SQL Queries On One Page Using JSTL

Jul 2, 2014

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)
%>

JSF :: Getting Null Values From XHTML Page To Java Code

Nov 13, 2014

My project consists of a web app where a user can select a area from a picture and f.e. if it is a office layout he can input the worker name and any peace of hardware that the area might have. In this case there are two categories: Hardware and Computer. Hardware - it has 5 dropdown lists consisting of printer, scanner and etc. Computer - like Hardware consists of many dropdown lists which add up to components such as processor, motherboard and etc. For me, considering this is my first ever web app project, is a huge step towards web development, I have used various mixes of Java, javascript and primefaces code.

My current problem: When a user selects an area he gets a dialog box where he is prompted to select his desired input, afterwards the user clicks the 'save' button and get's another dialogbox which has a resume of what he has selected so he could check out his input and save it by clicking the 'save' button in the resume box. My problem is that when the user clicks the save button the button calls a method which takes all the input and creates an Area object (Area object consists of various objects such as: Coordinates, Dimensions, Employee, ComputerList and HardwareList) and sends a query to the database, but all the values I get is null.

XHTML code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
