ZK How to update ListBox ListModel using selected item - java

I'm making a web file browser using ZK Components and find a block. Is there any way to update the ListBox model using the selected item of the listbox?
The use case is when traversing the files and folder, the user click the folder, and the list is refreshed with the content of the selected folder. The selection event is triggered and for regular file, it handle well, but not the folder.
My Code:
myfilesvm.zul
<zk>
<window apply="org.zkoss.bind.BindComposer"
viewModel="#id('vm') #init('com.my.zk.mvvm.MyFilesViewModel')">
<hlayout>
<listbox vflex="true" hflex="1" model="#load(vm.files)"
id="fileBrowser" selectedItem="#bind(vm.selectedFile)">
<auxhead>
<auxheader colspan="3">File List</auxheader>
<auxheader colspan="3">
<hlayout>
<!-- breadcrumb, implemented later -->
</hlayout>
</auxheader>
</auxhead>
<listhead>
<listheader label="Name" />
<listheader label="Size" />
<listheader label="Modified" />
</listhead>
<template name="model" var="file">
<listitem>
<listcell label="#load(file.name)" />
<listcell label="#load(file.length())" />
<listcell label="#load(file.lastModified())" />
</listitem>
</template>
</listbox>
</hlayout>
<separator />
</window>
</zk>

String homeFolder = "D:\\path\\home";
ListModel<File> files = new ListModelList<File>(Arrays.asList(FileCrumbManager.populateList(new File(homeFolder))));
File selectedFile;
#Init
public void init() { // Initialize
}
public ListModel<File> getFiles() {
return files;
}
#NotifyChange({ "selectedFile" })
public void setFiles(ListModel<File> files) {
this.files = files;
}
public File getSelectedFile() {
return selectedFile;
}
public void pilihFile() {
if (getSelectedFile().isDirectory()) {
log.info("File is a directory");
this.files = new ListModelList<File>(
Arrays.asList(FileCrumbManager.populateList(new File(getSelectedFile().getAbsolutePath()))));
} else {
try {
Filedownload.save(getSelectedFile(), null);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
log.error(e.getMessage());
}
}
}
public void setSelectedFile(File selectedFile) {
this.selectedFile = selectedFile;
pilihFile();
}
}
Appreciate for any help. Thank you.


The correct way to refresh ListModelList in pilihFile() is:
this.files.clear();
this.files.addAll(Arrays.asList(FileCrumbManager.populateList(new File(getSelectedFile().getAbsolutePath()))));
Because Listbox is model-driven rendering, you should control the rendering by manipulating the model object. When you call methods of ListModelList, it will notify Listbox to render into a browser. If you replace this.files with a new object, ZK doesn't know it. That's why your browser doesn't have the update.

Connecting SQL Server with Java (javafx)

I have the setup below for the connection SQL Server with Java. Am also using javafx. I am very new to developing with Java. Note: I added the sqljdbc driver. I don't want to add main to DBConnection because am using the Connection method in the controller. Is there a way to fix this or how can I add main method without changing the connection method? Am getting error message:

Java programs require a main method as an entry point in order to run. The standard definition of a main method is like this:
public static void main(String[] args) {
// First code of your program goes here
}
This main() method should include the code that starts your application and loads any interface elements for display.
A JavaFX application also needs to have a class that extends Application and override its start() method.
Here is a very quick and dirty example of one such class:
import javafx.application.Application;
import javafx.stage.Stage;
class Main extends Application {
public static void main(String[] args) {
launch(args); // Starts the JavaFX application and calls the start() method
}
#Override
public void start(Stage primaryStage) throws Exception {
// Here is where you'll initialize your views and such
}
}
I would recommend taking a few Java and JavaFX tutorials to get a feel for some of the basics before attempting more complicated tasks like connecting to databases.

GXT Grid in ContentPanel messes up BorderLayout

EDIT
Although, thanks to Colin, the problems with the Grid itself are now fixed, the BorderLayoutPanel still initializes the grid on a strange (small) height and the middle border is nowhere to be found.
--
I have a GWT application that has a GXT viewport, containing a BorderLayoutContainer containing another BorderLayoutContainer, like so:
Now this works fine if I substitute my Grid for a GXT ContentPanel:
However, I am unpleasantly surprised when I implement the Grid:
The grid suddenly brings the size of the North component back to something smaller, it hides further under the header (the north component already has a margin-top of 10px), and the line between the grid and TabPanel can no longer be grabbed to resize the viewports. Also, one'd expect the grid to show scrollbars in this scenario. Also, on collapsing the Grid's ContentPanel, the center component doesn't proceed to fill up the leftover space as it should.
The Grid worked fine back when I used GWT panels (DockLayoutPanel, SplitLayoutPanel), so I proceeded to wrap the grid in a VerticalPanel (within a GXT ContentPanel). No changes ensued.

The relevant java is as such (constructor of the UiBinder's class):
initWidget(uiBinder.createAndBindUi(this));
osHeader.setMenuLabel(this.user.getLabel());
docGrid.fillGrid(user);
// Docgrid selection handler
docGrid.grid.getSelectionModel().addSelectionChangedHandler(new SelectionChangedHandler<DocumentNode>() {
#Override
public void onSelectionChanged(SelectionChangedEvent<DocumentNode> event) {
List<DocumentNode> selected = event.getSelection();
if (selected.size()>0) {
documentSelected(selected.get(0));
}
}
});

Add layout data to the Grid and PagingToolbar within the VLC in that widget. The toolbar probably should be set to be 100% width (i.e. width="1.0"), and use only the height it needs (height="-1"), and the Grid should use all width and all height (height="1.0" and `width="1.0"). This will probably look more or less like this (from http://www.sencha.com/examples/#ExamplePlace:paginguibindergrid)
<ui:with type="com.sencha.gxt.widget.core.client.container.VerticalLayoutContainer.VerticalLayoutData" field="middleData">
<ui:attributes width="1" height="1" />
</ui:with>
<ui:with type="com.sencha.gxt.widget.core.client.container.VerticalLayoutContainer.VerticalLayoutData" field="bottomData">
<ui:attributes width="1" height="-1" />
</ui:with>
<ui:with type="com.sencha.gxt.widget.core.client.grid.GridView" field="view">
<ui:attributes stripeRows="true" forceFit="true"></ui:attributes>
</ui:with>
<gxt:FramedPanel ui:field="panel" headingText="Grid UiBinder Example" pixelSize="600, 300"
collapsible="true" addStyleNames="margin-10">
<row:VerticalLayoutContainer borders="true">
<row:child layoutData="{middleData}">
<grid:Grid ui:field="grid" cm="{cm}" store="{store}" view="{view}" loadMask="true" columnReordering="true"
borders="false">
</grid:Grid>
</row:child>
<row:child layoutData="{bottomData}">
<toolbar:PagingToolBar pageSize="50" ui:field="toolBar"></toolbar:PagingToolBar>
</row:child>
</row:VerticalLayoutContainer>
</gxt:FramedPanel>
It is then also important that your class backing that xml file is capable of being resized by its parent. Either extend ResizeComposite to get that notification or implement RequiresResize and have that call the ContentPanel's own onResize function, or don't deal with Composite at all, but just implement IsWidget, and have asWidget() return the ContentPanel.
In this case you've got the Java resize wiring correct. However, if asWidget() is called multiple times, you will end up generating multiple copies of a widget - make sure this always returns the same one, probably by storing it in a field and checking if it is null (i.e. createAndBind hasn't been called yet).

ADF Faces multiple file upload

I am trying to create multiple file upload by using multiple af:inputFile component. Here is my xhtml:
<?xml version='1.0' encoding='UTF-8'?>

<f:view>
<af:document id="d1" title="Home">

</af:panelGroupLayout>
</af:form>
</af:document>
</f:view>
</jsp:root>
and this is the managed bean:
package com.edfx.massupload.bean;
import java.util.ArrayList;
import java.util.List;
import javax.faces.event.ActionEvent;
import oracle.adf.view.rich.component.rich.input.RichInputFile;
import oracle.stellent.ridc.IdcClientException;
import org.apache.myfaces.trinidad.model.UploadedFile;
public class MassUploadBean {
private List<RichInputFile> fileComponents = new ArrayList<RichInputFile>();
private List<UploadedFile> files = new ArrayList<UploadedFile>();
public MassUploadBean() {
super();
}
public void add(ActionEvent event) {
fileComponents.add(new RichInputFile());
files.add(null);
}
public void upload(ActionEvent event) throws IdcClientException {
for(UploadedFile file : files) {
System.out.println(file.getFilename());
}
}
public void setFiles(List<UploadedFile> files) {
this.files = files;
}
public List<UploadedFile> getFiles() {
return files;
}
public void setFileComponents(List<RichInputFile> fileComponents) {
this.fileComponents = fileComponents;
}
public List<RichInputFile> getFileComponents() {
return fileComponents;
}
}
The problems that I am facing are:
I have clicked on the Add button; a new file upload component added to the page; I browse a file; Again clicked on the Add button; Another file upload component added and the first file upload get submitted (but it is having a border, or something similar); I browse file from the second file upload; Again click on Add button; now the first file upload get cleared (reset) and the second file upload get submitted;
Whenever I clicked on the Add button the file get uploaded. Why? How to resist it? I have tried by setting atoSubmit="false" but no luck. Also tried to put the iterator, file uploader and the Upload button inside af:subForm
My requirement is to Upload the file when the upload button is clicked, not before.
Am I doing something wrong? Any pointer would be very helpful.

I see you're using IdcClientException which tells me you're uploading into UCM. If you're also using WebCenter then you might be able to use the out of the box Upload task flow that comes with WebCenter Portal: http://docs.oracle.com/cd/E29597_01/webcenter.1111/e25595/jpsdg_content_jsfpg.htm#autoId18
As of PS5 that task flow will do multifile upload for you.

THe later versions of ADF should help with bulk upload:
http://jdevadf.oracle.com/adf-richclient-demo/docs/tagdoc/af_inputFile.html
Turn on displayMode and maximumFiles (see also uploadType).

CookSwing - Retrieving the string from a textfield

I'm using CookSwing (http://cookxml.yuanheng.org/cookswing/) to build a Java Swing UI, but the site doesn't have a lot of information. I'm stuck trying to get my Java class to retrieve the string from a textfield in the form (declared in XML). This should be easy to do, but nothing I've tried works. Does anyone have experience doing this? Here is the Java class:
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import cookxml.cookswing.CookSwing;
public final class CookSwingForm
{
// Listener for the Quit button
public ActionListener exitAction = new ActionListener()
{
public void actionPerformed (ActionEvent e)
{
System.exit(0);
}
};
public CookSwingForm()
{
CookSwing cookSwing = new CookSwing(this);
cookSwing.render("sampleform.xml").setVisible(true);
}
public static void main(String[] args)
{
new CookSwingForm();
}
}
Here is the XML file ("sampleform.xml"):
<frame title="Sample Form" size="300,70"
defaultcloseoperation="EXIT_ON_CLOSE">
<borderlayout>
<constraint location="West">
<textfield columns="20" />
</constraint>
<constraint location="East">
<button text="Quit" actionlistener="exitAction" />
</constraint>
</borderlayout>
</frame>
I just need to have the Java class retrieve the string from the textfield that's declared in the XML file. Any help is greatly appreciated. Thanks!

I think you should use the id attribute and then use that as the variable name for the text field.
The xml would look as : <textfield id="box1" />
Here is what you have to do:
JTextField txtField = (JTextField) cookSwing.getId("box1").object;
//now,set some text
txtField.setText("Blah!");
//or get some text as you may wish
Also. Looks like the library is no longer being developed. That's a red flag right there.

Seam - ListSelectMenus with dependencies

I'm trying to build some select boxes with dependencies on other select boxes. I'm fairly new to Seam - just to add this. Here is my JSF - for test purposes I'm trying to display a dataTable
<f:facet name="header">Profil</f:facet>
<a:form ajaxSubmit="true" reRender="testTable">
<s:decorate id="techTypeField" template="layout/edit.xhtml">
<ui:define name="label">Choose tech</ui:define>
<h:selectOneRadio id="techType" value="#{technologyType}" onchange="submit()">
<s:selectItems value="#{technologyTypes}" var="elem" label="#{elem.name}" id="typeId"/>
<s:convertEntity/>
</h:selectOneRadio>
</s:decorate>
</a:form>
<div style="clear:both"/>
<h:dataTable var="productLine" id="testTable" value="#{productLines}" rendered="#{productLines.rowCount > 0}">
<h:column >
<f:facet name="header">pl</f:facet>
#{productLine.id}
</h:column>
</h:dataTable>
My backing bean
package de.ac.dmg.productfinder.workflow;
import java.util.List;
import javax.ejb.Remove;
import javax.ejb.Stateful;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import org.jboss.seam.annotations.Factory;
import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Logger;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.datamodel.DataModel;
import org.jboss.seam.annotations.datamodel.DataModelSelection;
import org.jboss.seam.international.StatusMessages;
import org.jboss.seam.log.Log;
import de.ac.entity.Machine;
import de.ac.entity.ProductLine;
import de.ac.entity.TechnologyType;
#Stateful
#Name("Profil")
public class ProfilBean implements IProfil {
#PersistenceContext
private EntityManager entityManager;
#Logger
private Log log;
#DataModel(value = "technologyTypes")
private List<TechnologyType> technologyTypes;
#DataModelSelection(value = "technologyTypes")
private TechnologyType technologyType;
#DataModel(value = "productLines")
private List<ProductLine> productLines;
#DataModel(value = "machines")
List<Machine> machines;
#In
StatusMessages statusMessages;
// add additional action methods
#Factory("technologyTypes")
public void loadTechTypes() {
technologyTypes = entityManager.createQuery("Select t from TechnologyType t").getResultList();
}
#Factory("productLines")
public void loadProductLinies() {
System.out.println(technologyType);
productLines = entityManager.createQuery("select p from ProductLine p where p.technologyType = :type ")
.setParameter("type", technologyType).getResultList();
}
public void next() {
// implement your business logic here
log.info("Profil.next() action called with: #{Profil.value}");
statusMessages.add("next #{Profil.value}");
}
#Remove
public void destroy() {
}
}
I can set the tech type on time - after one click it isn't refreshed sadly. What I'm doing wrong here?

When selecting a 'technology type', you need an action which reloades the product types based on the selected techtype. Something like action=#{Profil.loadProductLines()}
