"Unsupported major.minor version 51.0" on Mac

Mack06 — 2013-05-25T14:45:35

What versions of JDK do you have? It looks like the MAC has the wrong JDK version that you compiled your project as.

This setAutoRequestFocus? http://docs.oracle.com/javase/7/docs/api/java/awt/Window.html

What JDK version are you running? That is a JDK 7 function that is not valid in previous versions.

Re: Delay in appending text to TextArea box

Eduard Karel de Jong — 2013-05-24T17:26:11

Your code is run as event process, that means that no other UI events can be processed until your code is finished. while your code does modify a UI element, the update of that element is postponed till the next time an event is processed, so after your code.

All UI events are executed on the event Thread and it is a very bad idea to execute any time consuming code on that thread. Your delay loop is such time consuming code.

SWING has a timer class (http://docs.oracle.com/javase/7/docs/api/javax/swing/Timer.html) specially designed for what you want: you start it in the event process and when it is finished it does it's thing. In your case  change content of a text area.  For programed delay not related to the ui you can also use java.util.Timer.

cheers

< at >work I also my projects this way, as it was decided, that we want to

The action/menu entries in netbeans freeform projects call ant targets.

So if you have an ant target that runs your programm, you are good, if
not, you have to create one. (Hint: there is a java ant task).

You can modify the menu entries/mappings in the project.xml directly or
maybe easiert in the "Projects Properties" dialog.

Go to "Build and run". There you can map the default menu entries to ant
targets and also add more menu entries.

Agressive JNLP handling

Hervé Bitteur — 2013-05-24T12:22:14

Let me share this funny example, part of a Java project meant to be 
deployed with Java Web Start.

In the build.xml file, I wrote the following dummy targets, for the sake 
of demonstration :

    <target name="-jnlp-starting-some-name">
             <echo message="Hello from target -jnlp-starting-some-name"/>
         </target>
         <target name="-some-name-with-jnlp-in-it">
             <echo message="Hello from target -some-name-with-jnlp-in-it"/>
         </target>
         <target name="-some-name-ending-with-jnlp">
             <echo message="Hello from target -some-name-ending-with-jnlp"/>
         </target>

         <target  name="-post-jar"
                  depends="-some-name-ending-with-jnlp,
    -some-name-with-jnlp-in-it, -jnlp-starting-some-name">
         </target>


If, from the project properties / web start category dialog, I check the 
box "Enable Web Start", I can see the build.xml buffer modified 
instantly to the following:

    <target name="-jnlp-starting-some-name">
             <echo message="Hello from target -jnlp-starting-some-name"/>
         </target>
         <target name="-some-name-with-jnlp-in-it">
             <echo message="Hello from target -some-name-with-jnlp-in-it"/>
         </target>
         <target name="-some-name-ending-with-jnlp">
             <echo message="Hello from target -some-name-ending-with-jnlp"/>
         </target>
         <target depends="-some-name-ending-with-,
    -some-name-with--in-it, --starting-some-name" name="-post-jar"/>


You can notice that some reformatting has been performed in the 
"-post-jar" target. I don't know why, but this is no big deal.
What really puzzles me is the last line, read it carefully: the names 
that were listed in the dependencies of "-post-jar" target have been 
modified: all instances of "jnlp" string have disappeared!

Could we qualify this as a bug?
(if so, tell me where I can file a report)

Delay in appending text to TextArea box

gonzago — 2013-05-24T08:15:51

I have the code below in button 2. I expect to see the string "we are here" appended in my text area five times with a delay of a few seconds between each append. But that doesn't happen. Instead after a delay all five strings are displayed together at the same time. 

Can someone please explain why? and how to fix it? 

private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) { 
int j,k,m,n,x; 

for(j=0;j<5;j++) 
{ 
jTextArea1.append(j+"We are here \n"); 
for(k=0;k<100000;k++) 
{ 
for(m=0;m<10000;m++) 
for(n=0;n<10;n++) 
x=99*43; 
} 
}

Re: create executable in netbeans

For most project types select the project and click "Clean and build".  
In he "dist" directory of the project you will find the compiled jar.

Hi,

I would like to set the destination directory for a project depending on
platform and architecture.
The variable for the platform exists (CND_PLATFORM), but I can't find
any with the architecture (32 or 64 bits).

Does anyone know the easyiest way to do that ? I want to avoid setting
multiple configuration profiles.

Thank you in advance !

There is an appropriate 'code examples' forum

I'm going to post my question there, and maybe together we can get something started!

Looking for a beans wizard, plugin (or example)

sturdyworks — 2013-05-23T17:45:21

I'm new to JavaFX 2.0 (and Java) but have heard IDEs like NetBeans have wizards for bindings, properties, annotation type things? Are there wizards for the new JavaFx 2.0 Beans?

Reading the Apress book 'Pro JavaFx 2.0' says 'JavaFX 2.0 introduces the JavaFX Beans specification that adds properties support to Java objects through the help of the properties classes from the JavaFX 2.0 properties and bindings framework...with two Properties Strategies: Eagerly Instantiated, Lazily Instantiated.'

The recent post below mentions 'New --> Web Service Client' and if something like that did some setup for my application making a 'RESTful URL call' or 'Binding JSON data' to JavaFx Beans? (http://forums.netbeans.org/viewtopic.php?t=55290)

I can tell that many beans related examples (and client/server) are for Swing, AWT type applications and am hesitant to add plug-ins that are not appropriate for JavaFx 2.0.

Clicking on my NetBeans7.3->Tools->Plugins then Available Plugins tab, I can see plugins below, but is anything relivant to JavaFx Beans? Also, I have yet to find any plugin (e.g., RESTful Web Services) listed in Available Plugin out on (http://plugins.netbeans.org/PluginPortal/)

RESTful Web Services - Certified

2) Select "Libraries" from the left list, named "Categories".
3) Select "Add JAR/Folder" from the right button choices.
4) Find the jar file that you just downloaded and select it.

Java EE Base  Source: NetBeans

Support for additional Java EE technologies such as Java Persistence, JSF and JSF component suites, REST and SOAP web services, EJB or EAR projects needs to be installed and enabled separately, as well as support for more web frameworks such as Spring or Hibernate.


I hope I'm understanding some of this correctly--so much information :-)

Netbeans Design Time

turc0033 — 2013-05-23T17:13:53

I'm working on a projet that opens several UDP ports to communicate with a 3rd party device as soon as the app starts.  

So this is what happens:
When I have Netbeans 7.3 opened, I open my project.  Once the project is done loading / fully opened in Netbeans, the 3rd party device starts spitting out data to my computer (3rd party device is connected to my computer) - meaning that the program is running.  I used Wireshark (a packet sniffing tool) to verify that netbeans does open the ports and communicates (runs my code) with the 3rd party device.

In order to avoid this, I currently use the following call:

Code:

if(!Beans.isDesignTime())
{
    //Do not run this code in design mode
    ...
    ...
}




Now, I'm guessing that there is a setting in Netbeans to disable this "feature" (automatically runs program in background).

Netbeans Design Time

turc0033 — 2013-05-23T17:34:56

Figured out why:

Netbeans runs the code in the constructors so that it can display the GUI/components.  Since my program is fully automated, I have an Initialize() function in the constructor that starts some of my threads.  That function gets called and starts the communication process with the 3rd party device.
