New javafx properties in netbeans.

Hi everybody,
Is there a way to let netbeans automatically generate the new type of getters and setters for the javafx Property objects simply by selecting the Property fields in the code?
The same way it is done in eclipse.
I tryed using the "add JavaFx property" but this allows only to add a single javafx property at a time, but is not so convenient to add the various properties one by one this way.
Thanks!

Drag and Drop objects with JavaFX properties

Has anyone tried to implement drag and drop functionality with objects containing JavaFX properties? The issue I'm running into is that the objects appear to need to be serializable, and the JavaFX properties are not serializable. I can implement Externalizable instead of Serializable, and basically serialize the values contained by the FX properties, but of course I lose any bindings by doing this (as the listeners underlying the bindings are not serialized).
The [url http://docs.oracle.com/javafx/2/api/javafx/scene/input/Clipboard.html]javadocs for Clipboard state "In addition to the common or built in types, you may put any arbitrary data onto the clipboard (assuming it is either a reference, or serializable. See more about references later)" but I don't see any further information about references (and at any rate, this doesn't really make sense since anything that's serializable would be a reference anyway). Is there a special DataFormat I can use to specify a reference in the local JVM so the reference gets passed without serialization?
I know this might not make sense without a code example; I just thought someone might have come across this closely enough to recognize the problem. I'll try to post a code example tonight...

Here's pretty much the simplest example I can come up with. I have a real-world example of needing to do this, but the object model for the real example is quite a bit more complex.
For the toy example, imagine we have a list of projects, some employees, and we want to assign each project to one or more employees. I have a Project class with a title and assignee. (In real life you can imagine other properties; due date, status, etc.) I'll keep a ListView with a bunch of unassigned projects (titles but assignees equal to null) and then a ListView for each of the employees.
To assign a project to an employee, the user should be able to drag from the "master" list view to one of the employee list views. When the project is dropped, we'll create a new project, set the assignee, and bind the title of the new project to the title of the project which was dragged. (Remember we want to be able to assign a single project to multiple employees.)
So here's the first shot:
A couple of simple model classes
Project.java
import java.io.Externalizable;
import java.io.IOException;
import java.io.ObjectInput;
import java.io.ObjectOutput;
import javafx.beans.property.ObjectProperty;
import javafx.beans.property.SimpleObjectProperty;
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;
public class Project {
     private final StringProperty title ;
     private final ObjectProperty<Employee> assignee ;
     public Project(String title) {
          this.title = new SimpleStringProperty(this, "title", title);
          this.assignee = new SimpleObjectProperty<Employee>(this, "assignee");
     public Project() {
          this("");
     public StringProperty titleProperty() {
          return title ;
     public String getTitle() {
          return title.get() ;
     public void setTitle(String title) {
          this.title.set(title);
     public ObjectProperty<Employee> assigneeProperty() {
          return assignee ;
     public Employee getAssignee() {
          return assignee.get();
     public void setAssignee(Employee assignee) {
          this.assignee.set(assignee);
     @Override
     public String toString() {
          String t = title.get();
          Employee emp = assignee.get();
          if (emp==null) {
               return t;
          } else {
               return String.format("%s (%s)", t, emp.getName()) ;
}Employee.java
import java.io.Externalizable;

import java.io.ObjectOutput;
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;

     private StringProperty name ;
     public Employee(String name) {
          this.name = new SimpleStringProperty(this,"name", name);
     public StringProperty nameProperty() {
          return name ;
     public String getName() {
          return name.get();
     public void setName(String name) {
          this.name.set(name);

                    setGraphic(null);
                    setOnDragDetected(dragDetectedHandler);
}If you try to drag from the list on the left to one of the lists on the right, it will fail pretty quickly and tell you that the data need to be Serializable.
Simply adding "implements Serializable" to the Project and Employee classes doesn't work, as you find that SimpleStringProperty and SimpleObjectProperty are not Serializable. So instead I can use Externalizable:
public class Project implements Externalizable {
@Override
     public void writeExternal(ObjectOutput out) throws IOException {
          out.writeObject(title.get());
          out.writeObject(assignee.get());
     @Override
     public void readExternal(ObjectInput in) throws IOException,
               ClassNotFoundException {
          setTitle((String)in.readObject());
          setAssignee((Employee)in.readObject());
}and
public class Employee implements Externalizable {
     @Override
     public void writeExternal(ObjectOutput out) throws IOException {
          out.writeObject(name.get());
     @Override
     public void readExternal(ObjectInput in) throws IOException,
               ClassNotFoundException {
          setName((String) in.readObject());
}This makes the drag and drop work, but if you drop a project on one of the employee lists, then edit the project title in the master list, the binding is not respected. This is because deserialization creates a new SimpleStringProperty for the title, which is not the property to which the title of the new Project object is bound.
What I really want to do is to be able to drag and drop an object within the same JVM simply by passing the object by reference, rather than by serializing it. Is there a way to do this? Is there some DataFormat type I need?

JavaFX and the Netbeans platform

Hi,
Quick question...does anyone know if there are any plans or ongoing work to port the netbeans platform to JavaFX?
Nuwanda

Nuwanda, take a look at these links, perhaps they can help you:
http://blogs.oracle.com/geertjan/entry/deeper_integration_of_javafx_in
http://netbeans.dzone.com/javafx-2-in-netbeans-rcp
http://blogs.oracle.com/geertjan/entry/a_docking_framework_module_system
http://blogs.oracle.com/geertjan/entry/thanks_javafx_embedded_browser_for
I think the Netbeans RCP JavaFX strategy would be to enhance Netbeans RCP to provide better support for embedding JavaFX scenes in the platform.
Converting the platform to be written in JavaFX rather than Swing would not make much sense - such as thing would actually be a completely new platform in it's own right.

Request: Mechanism to generate JavaFX Properties

Hello,
I am making a request for some mechanism to generate JavaFX Properties. Maybe something for the eclipse IDE. I don't know if Netbeans has such a tool, but some of us are not current user of Netbeans.
Although JavaFX is a beauty to work with, the management/genaration of the properties is quite tedious.
Thanks

You may be interested in Re: Java(FX) Property Compiler "Java(FX) Property Compiler"
I don't think the JavaFX team will provide such a mechanism (well without it being perhaps created for something like Java9). You could file a request against the e(fx)clipse project and/or project Lombok.

CcBPM - what does meant "Create New Transaction" properties ?

Hi XI expert,
could you enligtheen me on what is the meaning of "Create new transaction" properties in step Send, Transformation in the ccBPM. When i need to tick this properties. ?
Cheers
Fernand

Specify whether the system is to create a separate transaction for the send step.
You can improve system performance if you define that the system is not to create a separate transaction for the send step. Note, however, that all messages to be sent are collected and not sent until the end of the relevant transaction. This is of particular importance for transactions that take a long time to execute.
An asynchronous sender step that waits for an acknowledgment must always be executed in a separate transaction.

Programmatically create a new fileRealm.properties

Hello,
Is there a way to programmatically create a new fileRealm.properties?
Imagine I've one soft platform which is based on the webLogic.when I
install the software I don't want to install webLogic again and create
a new domain in advance,so I want to create the domain during the
install and dynamicly generate the essential files including
fileRealm.properties.
Are there any best practices here?

When you add operation "Create with parameters", an action "createWithParams" is created inside your page definition file. If you look in the structure window on the left hand side of your screen, you will find it under the "bindings" node.
Right click on it and select "Insert inside ..." and then "NamedData". "NamedData" node will appear under the action "createWithParams".
Right click on it and select "Go to properties". There you will see attributes NDName, NDType and NDValue (you don't have to worry about the NDOption attribute).
Under NDName, write the name of the attribute you'd like to set.
Under NDType write the class type of this attribute (example: oracle.jbo.domain.Number ).
Under NDValue, write the default value of this attribute. This can be a direct value or EL expression.
Example:
+<action IterBinding="EmployeesIterator" id="Createwithparameters"+
InstanceName="AppModuleDataControl.Employees"
DataControl="AppModuleDataControl" RequiresUpdateModel="true"
Action="createWithParams">
+<NamedData NDName="FirstName" NDType="java.lang.String" NDValue="#{requestScope.userFirstName}"/>+
+</action>+
As you can see from the example above, my attribute is "FirstName", it is of type "java.lang.String" and its value should be derived from EL expression "#{requestScope.userFirstName}".
If you need help with the expression language, you can search for the document "The Java EE 6 Tutorial Volume II Advanced Topics" on Google. It contains an overview of EL. Useful stuff :)

p.s. You can also buy the "Jdeveloper 11g Handbook". It's a great resource of information :)

Javafx properties not displaying in Netbeans

The property pane comes up but when I select a component no properties are displayed. Netbeans 6.9 RC2.
Thoughts?
Thanks.

I have found the same bug, using Netbeans 6.9.1 and developing a JavaFX GUI. When I add a component to my design scene, and then select that component and try to view its properties in the Properties window, it displays <No Properties>. Have you found a solution to this problem? I have submitted this as a bug to NetBeans.org to see if they can make sense of it.

Profiling JavaFX project with Netbeans

Hello,
I'm trying to profile my application with the built-in netbeans profiler.
But when I click the 'Run' button, the message 'Connecting to the target VM...' does not disappear anymore...
What could be the problem?
thanks

I've installed a 64 bit JDK and additionally a JRE , where I'm not sure if this is 32 or 64 bit.. I thought having downloaded a 64 bit version, but the system wanted to locate it in the 'Program Files (x86)' folder (Win 7).
The jvisualvm does not really support my javafx applications.
They're listed as <Unknown application> and eg. at the 'System properties' tab only the message 'Not supported for this JVM' is shown.
Tell me if you need some more informations viewed in jvisualvm!
thanks
P.S. i had massive problems with installing the java staff under Win 7. After first installation java did not work in Firefox. So I had to experiment with uninstalling / installing again and the env variables. Now it works with Firefox too and all my apps can be run in netbeans. But the Java symbol in the Control Panel does not work, and the 'java -version' command results in " Error: could not open `C:\Java\jre6_x86\lib\amd64\jvm.cfg' "
amd64 in the path ?? I have Intel. I'm really scared .....

Create web service client for javafx project in netbeans 6.8

I here have a javafx project and need to create a web service client for it (in netbeans 6.8).
However when I right click this project -> new -> web service client -> input wsdl location\package -> finish, it seems that the client code is never generated. This is quite different from what happens when creating web service client for a java project.
Anyone knows how is this happening?

Thanks for your reply.
I did write my own ws client code but I need to create a web proxy based on an appointed wsdl path. That requires me to create a web service client from netbeans 6.8, like what I described in my first post. Unfortunately, it's not behaving like what I imagined it should do for a java project, even the javafx file itself doesn't have any error. The error occurs in package definition line.
package fx;For the definition above, it cannot access java.lang.builtins.
The question now is about the possibility to include javafx file in an non-javafx, say, java project. Any comments?
---Regards.
