• Maven Command Line for NetBeans RCP Developers

  - by Geertjan

  In the ongoing work being done on Maven documentation support for NetBeans Platform developers, the tutorial describing how to use the Maven command line to set up and develop applications on the NetBeans Platform has ben updated: http://platform.netbeans.org/tutorials/nbm-maven-commandline.html An interesting next step after following the tutorial above is to... open the result into the free community edition of IntelliJ IDEA: It's not hard to register the JDK and Maven in IntelliJ IDEA and to then run your application directly from there. The point is that there's no requirement to use NetBeans IDE if you want to create applications on top of its framework.

• Only can move the pointer after upgrading

  - by Mystogan

  I made a partition on my desktop pc, 100 GB and installed Ubuntu 12.10 on it. It was pretty slow first thought it had to install updates or something, so I rebooted it. Now after the login it looks like everything freezes, I can move my mouse only, but that's it! I can see my desktop and launcher, but the task bar doesn't display time and misc system info, only a black bar, I downloaded the Android SDK pack and installed vlc media player before I rebooted. My computer info: 1 TB HDD 8 GB ddr3 RAM ATI Radeon 4890 videocard (1 GB) AMD Phenom 2 x4 black 3, 2ghz CPU (64 bits)

• Solaris 11 features: nscfg

  - by nospam(at)example.com (Joerg Moellenkamp)

  As you may have noticed many configuration tasks around name services have moved into the SMF in Solaris 11. However you don't have to use the svccfg command in order to configure them, you could still use the old files. However you can't just edit them, you have to import the data into the SMF repository. There are many reasons for this need but the ultimate one is in the start method. I will explain that later. In this article i want to explain, how nscfg can help you with with the naming service configuration of your system. Continue reading "Solaris 11 features: nscfg"

• New Solaris 11.2 beta features: SMF stencils

  - by user13366125

  As much as there is often a lot discussion about configuration items inside the SMF repository (like the hostname), it brings an important advantage: It introduces the concept of dependencies to configuration changes. What services have be restarted when i change a configuration item. Do you remember all the services that are dependent on the hostname and need a restart after changing it? SMF solves this by putting the information about dependencies into it configuration. You define it with the manifests. However, as much configuration you may put into SMF, most applications still insists to get it's configuration inside the traditional configuration files, like the resolv.conf for the resolver or the puppet.conf for Puppet. So you need a way to take the information out of the SMF repository and generate a config file with it. In the past the way to do so, was some scripting inside the start method that generated the config file before the service started. Solaris 11.2 offers a new feature in this area. It introduces a generic method to enable you to create config files from SMF properties. It's called SMF stencils. (read more)

• *raine Trip Report (Lorraine & Ukraine)

  - by delabassee

  Last week, I had the opportunity to talk about Java EE 7 in Nancy (Lorrraine - France) and Kiev (Ukraine). The first event was arranged by the local Lorraine JUG while the second one was a largest conference organised by the Ukraine Java User Group. Based on the overall feedback and discussions I had during those two events, it is clear that the WebSocket API (JSR 356) is really a hot topic. And travel issues aside, I have really enjoyed my time during those two events. Thanks to both JUGs for having me! A more detailed report can be found on my personal blog.

• Screencast: "Unlocking the Java EE Platform with HTML5"

  - by Geertjan

  The Java EE platform aims to increase your productivity and reduce the amount of scaffolding code needed in Java enterprise applications. It encompasses a range of specifications, such as JPA, EJB, JSF, and JAX-RS. How do these specifications fit together in an application, and how do they relate to each other? And how can HTML5 be used to leverage Java EE? In this recording of a session I did last week at Oredev in Malmo, Sweden, you learn how Java EE works and how it can be integrated with HTML5 front ends, via HTML, JavaScript, and CSS.

• Hello Again, San Francisco

  - by Geertjan

  From the moment I got to the airport in Amsterdam, I've been bumping into JavaOne pilgrims today. Finally got to my hotel, after a pretty good flight (and KLM provides great meals, which helps a lot), and a rather long wait at customs (serves me right for getting seat 66C in a plane with 68 rows). And, best of all, on Twitter I've been seeing a few remarks around the Duke's Choice Awards for this year. The references all point to the September - October issue of the Java Magazine, where page 24 shows the following: So, from page 24 onwards, you can read all about the above applications. What's especially cool is that three of the above are applications created on top of the NetBeans Platform! That's AgroSense (farm management software), MICE (NATO system for defense and battle-space operations), and Level One Registration Tool (UN Refugee Agency sofware for managing refugees). Congratulations to all the winners, looking forward to learning more about them all during the coming days here at the conference.

• Warning and error information in stored procedures revisited

  - by user13334359

  Originally way to handle warnings and errors in MySQL stored routine was designed as follows: if warning was generated during stored routine execution which has a handler for such a warning/error, MySQL remembered the handler, ignored the warning and continued execution after routine is executed MySQL checked if there is a remembered handler and activated if any This logic was not ideal and causes several problems, particularly: it was not possible to choose right handler for an instruction which generated several warnings or errors, because only first one was chosen handling conditions in current scope messed with conditions in different there were no generated warning/errors in Diagnostic Area that is against SQL Standard. First try to fix this was done in version 5.5. Patch left Diagnostic Area intact after stored routine execution, but cleared it in the beginning of each statement which can generate warnings or to work with tables. Diagnostic Area checked after stored routine execution.This patch solved issue with order of condition handlers, but lead to new issues. Most popular was that outer stored routine could see warnings which should be already handled by handler inside inner stored routine, although latest has handler. I even had to wrote a blog post about it.And now I am happy to announce this behaviour changed third time.Since version 5.6 Diagnostic Area cleared after instruction leaves its handler.This lead to that only one handler will see condition it is supposed to proceed and in proper order. All past problems are solved.I am happy that my old blog post describing weird behaviour in version 5.5 is not true any more.

• Tissue Specific Electrochemical Fingerprinting on the NetBeans Platform

  - by Geertjan

  Proteomics and metalloproteomics are rapidly developing interdisciplinary fields providing enormous amounts of data to be classified, evaluated, and interpreted. Approaches offered by bioinformatics and also by biostatistical data analysis and treatment are therefore becoming increasingly relevant. A bioinformatics tool has been developed at universities in Prague and Brno, in the Czech Republic, for analysis and visualization in this domain, on the NetBeans Platform: More info:  http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0049654

• Theme is broken in some places

  - by RidiculeSwarm

  I am using a computer that started out on 11.10. I have since updated it several times, and installed and used a great number of WMs (Unity, XFCE, Gnome, KDE, Cinnamon). I am not sure how, but somewhere along the way (probably when I upgraded to Ubuntu 13.04), some parts of my desktop theme were broken. I have tried switching themes and installing new themes, but that does not work. Neither did a removal of (and log out/login cycle) the ~/.config/dconf folder work. Specifically: on several menus, the central part of a button icon is a "grey square" that doesn't fit in with the theme (picture below). the window and desktop right click menus looks ugly. The same kind of grey field covers the items, and the square checkbox looks weird (just filled with a uniform blue). The separator is a thick line that looks out of place. It seems to be a similar problem to that of window buttons (picture below).

• Recent EC Meetings - RIM forfeits EC seat

  - by heathervc

  Materials and minutes from the JCP EC Face-to-Face Meeting, held September 2012 in Prague, are now available on the EC Meeting Summaries page.  Topics included JCP.Next, a JCP 2.8 progress report, Inactive JSRs, and two Spec Lead presentations. In October 2011, new EC Standing Rules went into effect. The Rules include the following: "Missing five meetings in a row, or missing more than two-thirds of all meetings in any consecutive twelve-month period, results in loss of EC membership."  Last week, the JCP EC met for their October EC teleconference meeting.  RIM missed this meeting, and has now missed five meetings in a row (see the attendance chart); therefore, RIM has forfeited their EC membership. Results from the 2012 EC Elections will be available on 30 October.  The new merged EC will go into effect on 12 November.

• Reduced Tree View in NetBeans IDE 7.2

  - by Geertjan

  Right-click within the Projects window in NetBeans IDE 7.2 and from the "View Java Packages As" menu, you can now choose "Reduced Tree".I never really understood the difference between "Reduced Tree" and the already existing "Tree". But it makes sense when you see it. Here's Reduced Tree view: And here's Tree view, where you can see that the "actions" and "nodes" packages above each have their own top level package nodes, which takes up more space than the above: What's cool is that your selected package view is persisted across restarts of the IDE. To be complete, here's the List view, which is the third option you have in the "View Java Packages As" menu: Seems to me like the new Reduced Tree view combines the best of the Tree view with the best of the List view!

• JavaFX: Use a Screen with your Scene!

  - by user12610255

  Here's a handy tip for sizing your application. You can use the javafx.stage.Screen class to obtain the width and height of the user's screen, and then use those same dimensions when sizing your scene. The following code modifies default "Hello World" application that appears when you create a new JavaFX project in NetBeans. package screendemo; import javafx.application.Application; import javafx.event.ActionEvent; import javafx.event.EventHandler; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.stage.Stage; import javafx.stage.Screen; import javafx.geometry.Rectangle2D; public class ScreenDemo extends Application { public static void main(String[] args) { Application.launch(args); } @Override public void start(Stage primaryStage) { primaryStage.setTitle("Hello World"); Group root = new Group(); Rectangle2D screenBounds = Screen.getPrimary().getVisualBounds(); Scene scene = new Scene(root, screenBounds.getWidth(), screenBounds.getHeight()); Button btn = new Button(); btn.setLayoutX(100); btn.setLayoutY(80); btn.setText("Hello World"); btn.setOnAction(new EventHandler() { public void handle(ActionEvent event) { System.out.println("Hello World"); } }); root.getChildren().add(btn); primaryStage.setScene(scene); primaryStage.show(); } } Running this program will set the Stage boundaries to visible bounds of the main screen. -- Scott Hommel

• AntClassLoader bug exposed by forgetful NetBeans

  - by vbkraemer

  Many users have run into ClassNotFoundExceptions and NoClassDefFoundErrors after working with web services that target GlassFish while developing their projects in NetBeans. The issue usually appears as a dialog similar to this This can be pretty debilitating. The bug appears to be in the AntClassLoader, which is tickled by the wsimport ant task that ships with GlassFish 3.1.2. The fix is pretty simple: Upgrade the Metro bits that ship in 3.1.2 with bits that have had a patch applied. There are detailed instruction about installing the updated Metro bits onto GlassFish. This upgrade is probably useful for any install of GlassFish 3.1, but it is critically important for folks that develop web services from inside NetBeans and deploy them onto GlassFish 3.1.2.

• The Minimalist Approach to Content Governance - Manage Phase

  - by Kellsey Ruppel

  Originally posted by John Brunswick. Most people would probably agree that creating content is the enjoyable part of the content life cycle. Management, on the other hand, is generally not. This is why we thankfully have an opportunity to leverage meta data, security and other settings that have been applied or inherited in the prior parts of our governance process. In the interests of keeping this process pragmatic, there is little day to day activity that needs to happen here. Most of the activity that happens post creation will occur in the final "Retire" phase in which content may be archived or removed. The Manage Phase will focus on updating content and the meta data associated with it - specifically around ownership. Often times the largest issues with content ownership occur when a content creator leaves and organization or changes roles within an organization.   1. Update Content Ownership (as needed and on a quarterly basis) Why - Without updating content to reflect ownership changes it will be impossible to continue to meaningfully govern the content. How - Run reports against the meta data (creator and department to which the creator belongs) on content items for a particular user that may have left the organization or changed job roles. If the content is without and owner connect with the department marked as responsible. The content's ownership should be reassigned or if the content is no longer needed by that department for some reason it can be archived and or deleted. With a minimal investment it is possible to create reports that use an LDAP or Active Directory system to contrast all noted content owners versus the users that exist in the directory. The delta will indicate which content will need new ownership assigned. Impact - This implicitly keeps your repository and search collection clean. A very large percent of content that ends up no longer being useful to an organization falls into this category. This management phase (automated if possible) should be completed every quarter or as needed. The impact of actually following through with this phase is substantial and will provide end users with a better experience when browsing and searching for content.

• Is this CPU usage normal for Xorg?

  I checked System Monitor to see if the frequency of my CPU increases without doing anything and saw that xorg is always using 10-40% of the CPU even if it's not doing much of anything on the desktop or simply surfing the Internet. Is this normal? If not, how can I fix it? I have: a Macbook white 4,1 Core2 Duo running at 2.10 GHz GPU Intel GMA X3100 4GB of RAM Ubuntu 11.04 I am running Unity and I do not have many effects enabled.

• How to load kernel from live cd on UEFI install of Ubuntu 12.10?

  - by Geezanansa

  Running a GYGABYTE FM1 motherboard which is using a AMD 3870k APU with a new WS Caviar 1TB HDD. Following the advice in the Motherboard manual and https://help.ubuntu.com/community/UEFI have now got to grub screen for UEFI install. The dvd.iso being used is Ubuntu 12.10 desktop amd64. The hdd has had a gpt partition table made for, by using gparted when in a live desktop session(booted in bios mode)but decided to leave it unformatted with the intention of using installer to set up partitions. Booting live dvd gives grub list with the option to "install ubuntu" but get "can not read cd/0" and "the kernel must be loaded first" errors; when that option is selected. Any pointers on how to get installer going for UEFI install would be good. Thanks in advance.

• Poll: How long will you wait before using Solaris 11 on production systems?

  - by nospam(at)example.com (Joerg Moellenkamp)

  When Sun released Solaris 10, it was my first migration phase to a new Solaris major release while being part of Sun. At that time i heard a lot of comments between "Oh, we will install it on new systems on day 1" to "oh ... not that fast ... we will wait ... we are not that fast ... we will do it in a year". I would like to get some additional insight and so i set up the poll plugin for s9y to get the answer to the question "How long will you wait before using Solaris 11 on production system?". Thank you for your participation!
