How to change a file extension in NetBeans

2013-08-01T11:27:00.001-03:00

My friend Bruno Borges has asked NetBeans team to fix an issue about supporting extension changes in files during renaming. Looking about it I have found that NetBeans already support extension changes, not during renaming but it can be achieved using Properties view. I agree that it is a little bit hidden, so the idea here is write some words about it and make the user's life a little bit easier.

Basically what you need to do to achieve this is open Properties view in Window > Properties menu or using the shortcut Ctrl + Shift + 7. After that, select your file directly in Projects, Files, Favorites or even by opening it in the editor. Now, if you select a XML file for example, your Properties view should be something similar as the image below.

Now you can change the Extension property and the file type will be change as expected. I hope this little tip can help you.

Happy coding!

NetBeans IDE 7 Cookbook Review

2011-08-30T13:15:00.000-03:00

I have just read the NetBeans IDE 7 Cookbook, by Rhawi Dantas, so it is time for a quick review. This book, as most cookbook titles, is basically a collection of recipes which guide the reader, step by step, to accomplish each task. The recipes are divided basically in four sections:

Getting ready: helping the reader to organize the environment;
How to do it: a step-by-step guide throw the IDE interface;
How it works: a description of how it works and basically what the IDE do for you;
There's more: an additional description of how you can extend the procedure of the addressed task.

One of the first thing I always like to see in a book is if it is easy to read and specially easy to understand. NetBeans IDE 7 Cookbook is really ease to understand and the recipes are friendly to reproduce and follow. I should add that most images has a really good quality.

Another point I have liked at this book is that the first thing that is told at every chapter is what this chapter gonna cover and why it could be important for you, or not. It is really helpful when you are not a beginner.

There are some flaws at this book, that probably was caused by schedule issues. For example, this book focus on NetBeans IDE 7.0 but to follow the samples about JavaFX you need NetBeans 6.9.1. As far as I know, we can already use a beta support for JavaFX 2 at NetBeans 7.0. Another point is that there is no coverage for CVS at Version Control chapter. Some companies still use it and when you are migrating from another tool, this kind of information could be helpful.

My personal opinion is that this book is not intended for NetBeans advanced users, so if you already have experience with NetBeans, this book probably is not for you. If you are a beginner or are starting with NetBeans, this book will help you through some common development process using this amazing tool. If you would like to take a look at the book, you can read a sample chapter or even take a look at the official book's website for more information.

Happy coding!

NetBeans IDE 7 Cookbook review and another news

2011-07-28T09:25:00.002-03:00

First of all, probably some of you have already heard NetBeans has announced it has reached the mark of 1.000.000 active users. That is an impressive mark and we hope this tool could help even more people in the future. Following this good news, I have been contacted by Packt Publishing to read and review its new book NetBeans IDE 7 Cookbook, written by Rhawi Dantas. You can take a look in a sample chapter at the book's page too.

I am really happy to see another Brazilian guy working and writing about this amazing tool and eager to be here soon again talking more about this new NetBeans book and my impressions about it.

Happy coding!

How to set CVS compression for NetBeans IDE

2010-11-10T16:07:00.000-02:00

I was looking for how to use cvs compression inside NetBeans and I have just found the following message from Peter Pis:

On Mon, Jul 3, 2006 at 12:47 PM, Peter Pis wrote:

Hi Diego,
try to run netbeans with switch "-J-Dnetbeans.experimental.cvs.io.compressionLevel"

Example:

Level range = <0,10)

Regards,

It is really old but thanks to GMail I still have it and the NetBeans source code still looks for this option :D

I have done some initial tests and it really works as expected for NetBeans 6.9 and I hope it can help you as it will help me a lot.

NetBeans Platform 6.9 Developer's Guide review

2010-10-24T12:42:00.008-02:00

The first thing I would like to highlight is the foreword from Geertjan Wielenga, which makes clear this book has a target: introduce NetBeans Platform building a sample application from scratch and that "zero knowledge of the NetBeans Platform is assumed", but you should keep in mind that Java and Swing knowledge are required. If it is not what you are looking for, as suggested by Geertjan you could look for "The Definitive Guide to the NetBeans Platform" and "Rich Client Programming: Plugging into the NetBeans Platform" which continue to be the best detailed sources about NetBeans Platform APIs, together with the several NetBeans Platform tutorials, of course.

The 1st chapter introduces the reader to the modularization world, why it is necessary with simple explanation and of course many aspects of how NetBeans Platform try to solve this issues are explained with good theory and samples. The most interesting point in this chapter is not just the NetBeans module system but the OSGi support, the de facto module system.

The 2nd chapter summarize how to create and customize UIs using Matisse and chapter 3th how to use and organize your UI in a NetBeans Platform using the Window System. These chapter was well write with good examples to how create and organize the views for your application.

The 4th chapter probably is one of the most important chapter in this book which describes one of the most important NetBeans APIs: Lookup. In this chapter, you will learn how to communicate between modules in a loosely-coupled way.

The 5th chapter the author presents to us how to write global Actions and the 6th chapter, together with chapter 4th, we have the most important chapter in my opinion, presenting the Nodes API and the Explorer and Property Sheet API. Here you will learn how and when use nodes as well how to shows it in your application.

The next two chapters covers the FileSystem API and Datasystems API respectively. These APIs help you to work with the local file system, the NetBeans central registry and how to registry and work with your own file types.

The 9th chapter covers how to write dialogs and wizards and chapter 10th how to store settings and integrate your application with NetBeans Options dialog. The next chapter 11th we learn how to create help sets and integrate it to Help menu as well how to support context-sensitive help sets for each of our UIs.

For next you will learn how to set the branding of the application, defining a new name and title for the application as well how to change the splash screen and icons in the chapter 12th. The chapter 13th shows you how to distribute the application creating installers for several operating systems as well how to distribute it in a ZIP file and the last but not least how to write and support live updates for your application or modules.

The book was really well write, the language is really accessible and easy to understand, and the examples cover satisfactory the book target.
There are minor issues as every book but I recommend it mainly if you don't know the NetBeans Platform or just know it superficially. In my opinion the only complain about the digital version of the book is the images quality, most of them are hard to read and understand since it look distorted.

If you wish to see more details and buy the book, visit this page.

New GridBagLayout designer for NetBeans 7.0

The correct way to file a performance issue for NetBeans IDE

2010-04-12T22:35:00.003-03:00

Sometimes you feel your favorite IDE is slower or the memory consumption is higher than you expect so you usually file a bug but just a description is not enough to solve it. For this kind of issue the developers need more information as steps to reproduce and of course the heap and/or thread dumps of your system. Based on these informations some bottleneck could be identified and a solution implemented.

But get these information is not trivial for many users and NetBeans IDE has since version 6.7 a feature named Profile Me! or even Fitness Via Partnership which helps to make this task easier.

In this page you can see step by step how to get the thread dump from your system in the section Profile Me! and just below you can see the section Snapshot me! with details about how to get and send the memory dump. Many people are not aware about it so I hope this post could help you to file better issues to NetBeans project helping to make this the only IDE you need.

Happy coding!

How to solve NetBeans and Java editors problem when scrolling down large files under Linux the text becomes garbled, distorted or scrambled

2010-04-06T09:38:00.007-03:00

I am sure one image tell more than thousands of works, so here... we... go!

If you are experiencing this kind of behavior in your application, IDE or any kind of editor, don't worry so much, it is a misconfiguration of your video device and you can face it in several Java applications. Just to track the problem, some issues was filed against NetBeans Issuezilla and them was identified as a invalid issue, since it is a video card misconfiguration. After some searches and tests I realized how to solve the problem. I am current using a Ubuntu 8.10 with an Mobile Intel X3100 video card, which was automatically configured by Ubuntu in my xorg.conf file as below:

 
Section "Device"
Identifier "Configured Video Device"
EndSection

The first step to solve the problem is to know which display controller you are exactly using. To got it, I used lspci command line tool, where Display controller property will say what you need. Now, you just need to edit your /etc/X11/xorg.conf file with the code that follow and don't forget to backup your current xorg.conf file:

 
Section "Device"
Identifier "Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller"
Option          "AccelMethod"           "xaa"
Option          "RenderAccel"           "true"
EndSection

where Identifier should be your display controller. Now you just need restart your X server and back to work. For details about this solution, see this discussion and comments are really appreciated.

Another alternative is add a new property for JDK:


-Dsun.java2d.pmoffscreen=false

This should fix it too.

Happy coding!

New feature in NetBeans 6.9: Terminal and Remote Terminal Emulators

2010-03-26T18:15:00.001-03:00

A new feature just added to the IDE, at least I think so :), is the new option to use terminal directly inside the IDE. The terminal has all features all use at Ubuntu terminal so, it is pretty awesome for me. To access this go to 'Window > Output > Terminal' or 'Window > Output > Remote Terminal'. Take a look here a image about this new feature.

Thanks Michael to point me this new feature. :)
