I have requirement, in that I am showing a Datatable, above that table i have form in that i can register a employee, after clicking on submit employee data have to be saved in the database aswell as i have to update datable, so that I can see that registered employee in that Datatable, how can i full fill this requirement. I am using jsf 2.0, ejb3.0,jpa 2.0.
@Override
public List<Employees> getallEmployees() {
System.out.println("all employee fetched");
return (List<Employees>) em.createNamedQuery("Employees.findAll").getResultList();
}
In managed bean I am calling this service as fallow in init method, and i am binding same this. employee list to UI
public String getAllEmployeesfronHr() {
this.employees = customerservice.getallEmployees();
System.out.println(this.employees.size() + "=================size of employee");
return "";
}
For every submit button click i have to query database or is there any mechanism to update List / can we use entity manager in anyway so that we can update Employee List....
I am trying to create an array list without using the built in arrayList class that java has. I need to start the array being empty with a length of 5. I then add objects to the array. I want to check if the array is full and if not add a value to the next empty space. Once the array is full I then need to create a second array that starts empty and with the length of the first array + 1.
The contents of the first array are then copied into the new array without using the built in copy classes java has and then the new array ends up containing 5 elements and one null space the first time round. The first array is then overwritten with the new array containing the 5 elements and the null space. The process then starts again adding values until the array is full which will be 1 more value then recreating the second array empty and the length of the first array + 1. This is my attempt at creating this but I have run into multiple problems where I get only the last value I added and the rest of the values are null:
public class MyArrayList {
public Object arrayList[];
public MyArrayList(Object[] arrayList) {
this.arrayList = arrayList;

I have a strange behaviour when trying to update a bean. Here is the edit page:
<h3>Edit Post</h3>
<div class="row">
<h:form>
<div class="small-3 columns">

[Code] ....
Here is the bean class:
package com.airial.controllers;

postToUpdatet is always NULL. Why the title property is not binded ? What is wrong here ?

I have a requirement like in a Rich datatable, and i have placed two links up and down in one of the column of each row, here i wanted to swap rows (move up/ down ) the rows when i click the link on a perticular row. is it possible with jsf/ java script?

View Replies View RelatedWhen I have a datatable of primefaces with paginator and its only readable and not editable, its not needed to be inside of a form, right? although I have seen it many times inside of it
View Replies View Related1. If we have and xhtml page and we just have a datatable to show some records through a managed bean, I think there is no validation phase, apply request values phase... so it would be a faces request but not with the lifecycle of a jsf request, right?
2. In the previous case because the normal phases of a jsf request are not going to be called, the method that will be called in the backing bean to get the records, could be called more than once although its not a normal faces request?
I am having a hard time trying to wrap my head around trying to get a couple of columns in a datatable populated with values from a @OneToMany collection. The concept is simple but my brain refuses to grasp it!! I will try to make this brief...
I have several forms built with primefaces 3.5 using NetBeans 8 IDE on a JBoss EAP 6.21 server, and JPA 2.1 annotations. Data is extracted from an Oracle 11 database, which consists of several lookup tables, as well as a primary table and secondary table. Using the EntityManager createQuery method I query the database, which of course returns a resultset. The query grabs all records from the primary, as well as values from 2 specific columns of the secondary database, based on search criteria entered by the user on a primefaces search form. The returned results are then iterated through, this is where I am trying to get the values from the secondary table to populate specific fields in the datatable.Here is the applicable code from the list.xhtml form containing the datatable:
<p:dataTable id="datalist" value="#{foreignPartyController.returnedSearchResults}" var="item"
selectionMode="single" selection="#{foreignPartyController.selected}"
paginator="true"
rowKey="#{item.foreignPartyId}"
rows="30"
rowsPerPageTemplate="10,20,30,40,50"
sortOrder="ascending"
resizableColumns="true"
style="overflow: auto"
[code]....
As odd as the code may look (and I will completely understand anyone cringing as to some of the coding methods I use), specifically with the ui:repeat tags nested inside the datatable tag of the list.xhtml form, I strangely do see the values from the secondary table showing up in the form showing the results in a datatable. However, when the user clicks on a specific record in the returned resultset listed in the datatable, another form is opened and populated with the values from the datatable, but the 2 fields on that form that should be populated with the 2 values I referred to before from the secondary table (i.e. policy1Num and totalPayoutAmt) do not have the values in them.
This is partly because I have those 2 fields in the editable form pointing to the managed bean of the secondary table (code from that bean not shown here), rather than the same "polNum. policy1 Num" and "totPayout.totalPayoutAmt" var I am using in the list.xhtml form. How those values are being successfully returned into the datatable of the list.xhtml form - I happened to "stumble" across the use of the "polNum" and "totPayout" vars with the "policy Payment Collection" list. I do not know how to do the same thing for those 2 fields in the editable form.how a datatable gets populated, specifically with values in a @OneToMany collection,
I used Primefaces 4.0.7.I has trouble with checkboxes, which are not change,with unselected checkboxes when I press . I mean, i selected someone from selectone menu in my bsPanel(first panel) and then the datatable fills with his/her duty.Then I select all the duties in the datatable to assign to someone else in bilgiPanel. Then duties assign this person and then i choose same person in the top panel(bsPanel),then datable seems with selected sutiesHere xhtml file;
<p:panel id="bsPanel" header="#{etiketler.personel}" collapsed="false" toggleable="true" >

I want to write a little java program that when ran it will add information to my host file. A screen will pop up with a button on it. When you click the button it will add a few ip to domain connections. In order to edit the host file with notepad you must first give notepad admin privileges. I can't find a way to do this and I'm extremely fresh to programming. Is there a way I can write directly to the file or is there a way to run notepad with elevated privileges?
View Replies View RelatedI have been developing what I intent to be a base class for several forms that will allow the user for adding / editing / deleteing records. These records could be customers, products, suppliers etc.
I have designed a basic form that has an add, edit and delete button. For the add button, I would want to clear all the values in all of the controls (textboxes, combox etc) in preperation for adding a new record.
My question is this. Is this something I should do in the base class OR should it be handled in the classes that will extend from the base class? Perhaps if the controls were datalinked to the data they will clear themselves (I haven't got that far yet so I dont know). I thought maybe I could write code in the base class that could loop through all of the controls and call this from the extended classes.

But when I tried to write another app which is basically the exact same thing just a different sentence, I keep getting a bunch of error codes saying illegal character. I did everything the exact same. I am using Text Edit on a Mac and using Terminal to execute the Java code.

I extracted a jar file and decompiled one of the classes using jad in order to made a small edit (the original jar was looking to load an image file in the current directory, I replaced the current directory with an environmental variable). I went and recompiled that class. It complained that it cannot find some swt classes, so I downloaded swt.jar for Linux from the Eclipse website and specified the classpath to contain it. It compiled fine and I repacked the jar file. But when I tried to execute it I got:
Java Code: Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/swt/widgets/Decorations

I do not get the same error when I execute the original jar file (that complains that it cannot find the image file unless I put the image in the directory I execute it from). I even tried putting swt.jar in the classpath during execution:
