when I look at javaee-api it has javax.enterprise.context.ApplicationScoped and javax.inject.Named which are the particular imports being used in the bean. The facelets part is working, the template navigates correctly. It deploys to Glassfish and runs, except...there's no output from the @Named bean:
package dur.beans; import javax.enterprise.context.ApplicationScoped; import javax.inject.Named; @Named("nextClient") @ApplicationScoped public class NextClient implements NextClientLocal {
[code]...
Now it's working. I can't figure what I did for the life of me...that's the desired output, each time the page is accessed the counter increments.Now it works. Is this on the right track? Way off base? I have an entity class from a database which I'd like to link up to this, and output the class.I can inject the entity into NextClient? I'm trying to do the "R" for Read in a CRUD application with CDI and facelets (using templates).
I've found much reference material on EJB, but it seems a mishmash. I just want to use CDI. What am I doing right/wrong, or, besides the PDF from Oracle on Java EE 7, what are good CDI reference material's?
I am working on eclipse kepler, JSF 2.2 with PrimeFaces 4.0 / Mojarra 2.2 library.
actually there are 2 Problems:
I still get this server message no matter what I do.
(( javax.el.PropertyNotFoundException: /Order.xhtml @28,76 value="#{kk.refugee.id}": Target Unreachable, 'refugee' returned null))
and if I delete the input text puls the hidden, the message keeps pop up for 'material' selectOneMenu. -
I have no chance to examin : ((is this javascript code correct, to copy the value of one component to the other.)) these are my xhtml file and java calsses.
**kk.java** ----------- package khldqr.beans; import javax.faces.bean.ManagedBean; import javax.faces.bean.SessionScoped; @SessionScoped @ManagedBean public class kk {
In my Icefaces 3 application I have a ManagedBean ancestor that defines common attributes to those they spread it. Including CSS styles to be apply at the menu as icons depending on whether they are selected or not. Classes that extend the CommonMBean class define styles. My question is what do I have to put in the language experssion styleClass to tell him that the getter to use is that of the parent class.
CommonMBean.java package com.omb.view; public class CommonMBean private String menu1Css = ""; private String menu2Css = "";
I am new to JSF and when i try to implement a sample application im getting this wierd error of page not found(.xhtml). Here is the code i have created..
Bean class :
package com.trail.beans; import javax.faces.bean.ManagedBean; import javax.faces.bean.SessionScoped; @ManagedBean @SessionScoped public class UserLoginBean {
And in the server getCustomerList() accessed to database, how many times getCustomerList() would be called from I request the xhtml page?. I have read this would be called several times because of JSF internals and It would be better to store it in a variable and access this variable.
1. Is this true this would be called several times? why?
2. If the previous statement was true, how to avoid it, I mean not call the method from a service?
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.

1. All jsf tags like datatable, form, etc.. will generate UIComponents in server side, right?
2. All non JSF tags will not generate UIComponents in server side, right?
3. If you want something in a view that will be the same across users and requests, I mean, It will not change like a label tag, it doesn't make any sense to create it with a JSF tag in order to save memory in server side, right?
I am developing a web application using JSF-2.0 on weblogic 10.3.6. I am using Facelets as VDL. I have 5 different machine. They are different according to their OS and their geographical location. On my first xhtml page server (machine) is decided. Then on next page file upload and rest of processing takes place. My restriction is that SSO configuration can be done on only one machine.
So I am restricted to using xhtml files from only my primary server where SSO configuration is done. But I have to connect to servlets or managed-bean of different machine as requests are machine specific and file needs to be uploaded to those machines for processing. So I cannot use redirectUrl as I need to be only on one machine. Is it possible that xhtml on one server can talk to managed-bean on other server(different machine)?.
When i access to this page and save it as xml in realtime, the tags in xml file saved is empty while it is initialized and everything is working properly.
<edges> </edges>
How can i access to content of this xhtml page and save it on disk?
I am working on a project that uses a custom tag in a JSP file. Here is the tag descriptor
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN" "http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd"> <taglib> <tlibversion>1.0.0</tlibversion> <jspversion>1.1</jspversion>
[code]...
Everything seems working fine except that the custom tag handler does not get called at call. I set breakpoint and it never stops there. The JSP page is displayed fine, only not showing the custom tag content and there is no logged error/warning from the log. The tld is found fine. Like what classes called/validated the tag handler so I can logging those classes at DEBUG level to see what goes wrong.
I would like to create a custom tag which works similar to <c:forEach/> tag i.e
<c:forEach var = "movie" items = "${collection}> ${movie} </c:forEach>
I would want to create the similar behaviour(as above) in my own custom Tag.Morever I would like to use the doStartTag() and doEndTag() and doAfterBody() methods while creating custom Tag.
My jsp page needs to have a dropdown box. on selecting one/more than one values from this list, the same values get populated in another one.. we have a delete button too , it allows to populate the second box again.
The thing is i am to avoid scripts and use custom tags as much as i can...
I am supposed to implement a custom Map interface and I'm having some trouble with this method:
// 1. From the interface /** * Gives an iterator iterating over the key set from the smallest key that is not less than the key provided. * @param key the key * @return the iterator * @throws NullPointerException if key == null */
public Iterator<Key> tailIterator(Key key);
[Code] .....
My implementation is wrong according to a JUnit test. Also, to get a full score this method should have a worst case running time of O(log N), which obviously isn't the case now. (My Map implementation is currently based on binary search in an ordered array, keeping a prallel array for the values).
I'm having trouble creating a highly efficient algorithm for counting within a custom scale. This problem applies to futures trading, specifically treasuries contracts.
One specific treasury contract has 32 units before rolling over to the next whole number. So, the price scale looks something like this ...
If I pick a number (price) at random, let's say 1 28, and I want to add 8 units to that value, I should end up with 2 4. I can do this using brute force, calculating remainders, etc, etc....

I cant custom my own icon. There is no error. But the image that I tried to show in the joptionpane is not showing. What should i do?
I have a java code that should sort an array of names based on the last name. e.g jane a, jane b, jane z, jane d should be jane a, jane b, jane d, jane z. I have the following code but for some reasons, the s1 in the comparator method is always null.
public class ShuffleName { public static void sortNames(String[] names){ Arrays.sort( names, new Comparator<String>() { public int compare( String s1, String s2 ) { String s1last = s1.split("s+")[1]; String s2last = s2.split("s+")[1]; return s1last.compareTo(s2last);
my application shows a profile. The profile has various interactors. I'm trying to follow the MVC model, so I neeed to tell my controller that something was selected. But the profile has many elements that can be selected(mostly labels, so not setActionCommand), how do I tell it WHICH one was it?
how do I separate those interactors? I created a HashMap that maps from JLabels to Strings. When a mouse event occurs I loop trough it to search for the event source. If I find it I fire my custom event.
I would like to ask about JTree custom renderer. What could be wrong with this. Here's the deal:
I have a Jtree which suppose to view the structure of given folder, so far so good its working. But my problem is that i dont want it to show the full path as name, only folder name and file name. I wrote a custom JTree renderer in hope that this will solve my problem but it didn't.
Here is my custom Jtree renderer:
private static class MyTreeCellRenderer extends DefaultTreeCellRenderer { @Override public Component getTreeCellRendererComponent(JTree tree, Object value, boolean sel, boolean expanded, boolean leaf, int row, boolean hasFocus) { super.getTreeCellRendererComponent(tree, value, sel, expanded, leaf, row, hasFocus); if( value instanceof DefaultMutableTreeNode){
