  • Secure copy uucp style

    - by Alexander Janssen
    I often have the case that I have to make a lot of hops to the remote host, just because there is no direct routing between my client and the remote host. When I need to copy files from a remote host two or more hops away, I always have to: client$ ssh host1 host1$ ssh host2 host2$ scp host3:/myfile . host2$ exit host1$ scp host2:myfile . host1$ exit client$ scp host1:myfile . Back when uucp still was being used this would be as simple as a uucp host1!host2!host3 /myfile . I know that there's uucp over ssh, but unfortunately I don't have the proper privileges on those machines to set it up. Also, I'm not sure if I really want to fiddle around with customer's machines. Does anyone know of a method doing this tasks without the need to setup a lot of tunnels or deploying new software to remote hosts? Maybe some kind of recursive script which clones itself to all the remote hosts, doing the hard work for me? Assume that authentication takes place with public keys and that all hosts do SSH Agent Forwarding. Edit: I'm not looking for a way to automatically forwarding my interactive sesssion to the nexthop host. I want a solution to copy files bangpath-style using scp via multiple hops without the need to install uucp on any of those machines. I don't have the (legal) rights or the privileges to make permanent changes to the ssh-config. Also, I'm sharing this username and hosts with a lot of other people. I'm willing to hack up my own script, but I wanted to know if anyone knows something which already does it. Minimum-invasive changes to hosts on the bangpath, simple invocation from the client. Edit 2: To give you an impression of how it's properly been done in interactive sessions, have a look at the GXPC clustershell. This is basically a Python-script, which spwans itself over to all remote hosts which have connectivity and where your ssh-key is installed. The great thing about it is, that you can tell "I can reach HostC via HostB via HostA." It just works. I want to have this for scp.

  • Include a version control tag in VSS

    - by Sjuul Janssen
    I was reading Code Complete 2 and it mentions this: Many version-control tools wil insert version information into a file. In CVS, for exmple the characters // $id$ Will Automaticly expand to // $id: ClassName.java, v 1.1 2004/02/05 00:36:42 ismene Exp $ So now I would like to do something similar with VSS for our SQL scripts I have been googling around for the answer but can't find it. Is this possible? can someone maybe point me in the right direction?

    I got the following trigger on my sql server 2008 database CREATE TRIGGER tr_check_stoelen ON Passenger AFTER INSERT, UPDATE AS BEGIN IF EXISTS( SELECT 1 FROM Passenger p INNER JOIN Inserted i on i.flight= p.flight WHERE p.flight= i.flightAND p.seat= i.seat ) BEGIN RAISERROR('Seat taken!',16,1) ROLLBACK TRAN END END The trigger is throwing errors when i try to run the query below. This query i supposed to insert two different passengers in a database on two different flights. I'm sure both seats aren't taken, but i can't figure out why the trigger is giving me the error.

  • IOUC Summit: Open Arms and Cheese Shoes

    - by Justin Kestelyn
    Last week's International Oracle User Group Committee (IOUC) Summit at Oracle HQ was a high point of the past year, for a number of reasons: A "quorum" of Java User Group leaders, several Java Champions among them, were in attendance (Bert Breeman, Stephan Janssen, Dan Sline, Stephen Chin, Bruno Souza, Van Riper, and others), and it was great to get face time with them. Their guidance and advice about JavaOne and other things are always much appreciated. Mix in some Oracle ACE Directors (Debra Lilley, Dan Morgan, Sten Vesterli, and others), and you really have the making of a dynamic group. Stephan describes it best: "We (the JUG Leaders) discovered that behind the more formal dress code the ACE directors are actually as crazy as we are." (See link below for more.) Thanks to Bert's (NLJug) kindness, I am now the proud owner of a bonafide, straight-from-the-NL cheese shoe. How the heck did he get this through security? I suggest that you also read more robust reports from Stephan, Arun Gupta, and of course "Team Stanley."

  • New Java EE/GlassFish Testimonial

    - by reza_rahman
    As you may be aware, we have been making a concerted effort to ask successful Java EE/GlassFish adopters to come forward with their stories. A number of such stories were shared at this year's GlassFish Community event at JavaOne. In addition to Adam Bien's testimonial (which we posted earlier), another story that really stands out is the one from Stephan Janssen. Stephan is one of the main organizers of Devoxx and the webmaster of the popular Parleys e-learning platform. Parleys, which won the Duke's Choice award this year, runs on GlassFish as does the Devoxx CFP/registration website. Stephan's story is particularly interesting because he talks about his reasons and experience of moving from Tomcat to GlassFish and from Spring to Java EE. See what Stephan had to say here.

  • Parleys Testimonial at GlassFish Community Event, JavaOne 2012

    - by arungupta
    Parleys.com is an e-learning platform that provide a unique experience of online and offline viewing presentations, with integrated movies and chaptering, from the top notch developer conferences and about 40 JUGs all around the world. Stephan Janssen (the Devoxx man and Parleys webmaster) presented at the GlassFish Community Event at JavaOne 2012 and shared why they moved from Tomcat to GlassFish. The move paid off as GlassFish was able to handle 2000 concurrent users very easily. Now they are also running Devoxx CFP and registration on this updated infrastructure. The GlassFish clustering, the asadmin CLI, application versioning, and JMS implementation are some of the features that made them a happy user. Recently they migrated their application from Spring to Java EE 6. This allows them to get locked into proprietary frameworks and also avoid 40MB WAR file deployments. Stateless application, JAX-RS, MongoDB, and Elastic Search is their magical forumla for success there. Watch the video below showing him in full action: More details about their infrastructure is available here.

  • GlassFish Back from Devoxx 2011 Mature Java EE 6 and EE 7 well on its way

    - by alexismp
    I'm back from my 8th (!) Devoxx conference (I don't think I've missed one since 2004) and this conference keeps delivering on the promise of a Java developer paradise week. GlassFish was covered in many different ways and I was not involved in a good number of them which can only be a good sign! Several folks asked me when my Java EE 6 session with Antonio Goncalves was scheduled (we've been covering this for the past two years in University sessions, hands-on labs and regular sessions). It turns out we didn't team up this year (Antonio was crazy busy preparing for Devoxx France) and I had a regular GlassFish session. Instead, this year, Bert Ertman and Paul Bakker covered the 3-hour Java EE 6 University session ("Duke’s Duct Tape Adventures") on the very first day (using GlassFish) with great success it seems. The Java EE 6 lab was also a hit with a full room of folks covering a lot of technical ground in 2.5 hours (with GlassFish of course). GlassFish was also mentioned during Cameron Purdy's keynote (pretty natural even if that surprised a number of folks that had not been closely following GlassFish) but also in Stephan Janssen's Keynote as the engine powering Parleys.com. In fact Stephan was a speaker in the GlassFish session describing how they went from a single-instance Tomcat setup to a clustered GlassFish + MQ environment. Also in the session was Johan Vos (of Mollom fame, along other things). Both of these customer testimonials were made possible because GlassFish has been delivering full Java EE 6 implementations for almost two years now which is plenty of time to see serious production deployments on it. The Java EE Gathering (BOF) was very well attended and very lively with many spec leads participating and discussing progress and also pain points with folks in the room. Thanks to all those attending this session, a good number of RFE's, and priority points came out of this. While this wasn't a GlassFish session by any means, it's great to have the current RESTful Admin and upcoming Java EE 7 planned features be a satisfactory answer to some of the requests from the attendance. Last but certainly not least, the GlassFish team is busy with Java EE 7 and version 4 of the product. This was discussed and shown during the Java EE keynote and in greater details in Jerome Dochez' session. If any indication, the tweets on his demo (virtualization, provisioning, etc...) were very encouraging. Java EE 6 adoption is doing great and GlassFish, being a production-quality reference implementation, is one of the first to benefit from this. And with GlassFish 4.0, we're looking at increasing the product and community adoption by offering a pragmatic technical solution to Java EE PaaS deployments. Stay tuned ! (the impatient in you is encouraged to grab a 4.0 build and provide feedback).

  • Favorite moments of JavaOne

    - by Tori Wieldt
    There are so many events and sessions to attend at JavaOne, it's unfair to ask people to choose just one thing they liked, but here are some favorite moments: I loved meeting many open source contributors and friends I have not met in person before and seeing that projects like e.g. Hudson are alive and kicking and have a great future ahead of them. -Manfred Moser My "The Problem with Women" session. It had LOADS of interactivity from the audience, who really helped to make that session.  I came out if it with a real sense of optimism - we love our jobs, we love what we do, and we should be proud of telling everyone about it to attract different talent into the industry. (Read her blog JavaOne: The Problem With Women - A Technical Approach for details.) -Trish Gee My kudos to Oracle for making the presentation materials quickly available to the public. Some of them were already available during JavaOne. Lots of slide decks are already there, and in some cases you may even find the video recordings too. Go to http://www.oracle.com/javaone and select JavaOne Technical Sessions.  -Yakov Fain I loved that not only was James Gosling present at the Community Keynote (which felt more like the keynotes of old times [big space, big screens, fun and tech]) but he was also found wandering the halls of the Hilton the day prior. Bring back James! Add back the toys section in the Community Keynote. Let the t-shirt tossing begin anew. These are "small" things that really fire up the community. -Andres Almiray Seeing James Gosling at JavaOne was a real shot in the arm for Java.  He needs to be there every year. -Frank Greco +42 on having James and the T-shirt tossing. -Stephan Janssen The session "Integrate Java with Robots, Home Automation, Musical Instruments, and Kinect." Fabiane Nardon explained connecting Jenkins to jHome to a truck horn placed in their sysadmin's bedroom. She dubbed it "extreme feedback."  -Tori Wieldt The User Group Forum [on Sunday] was a success! Congratulations Bruno Souza and John Yeary and everybody that were involved. I believe it really helps to increase community participation! There were lots of interesting talks, and great discussion with JUG leaders and members. Thank you Oracle for supporting that! -Yara Senger What was your favorite moment? Please comment!

  • Creative, busy Devoxx week

    - by JavaCecilia
    I got back from my first visit to the developer conference Devoxx in Antwerp. I can't describe the vibes of the conference, it was a developer amusement park, hackergartens, fact sessions, comic relief provided by Java Posse, James Bond and endless hallway discussions.All and all - I had a lot of fun, my main mission was to talk about Oracle's main focus for OpenJDK which besides development and bug fixing is making sure the infrastructure is working out for the full community. My focus was not to hang out at night club the Noxx, but that was came included in the package :)The London Java community leaders Ben Evans and Martijn Verburg are leading discussions in the community to lay out the necessary requirements for the infrastructure for build and test in the open. They called a first meeting at JavaOne gathering 25 people, including people from RedHat, IBM and Oracle. The second meeting at Devoxx included 14 participants and had representatives from Oracle and IBM. I hope we really can find a way to collaborate on this, making sure we deliver an efficient infrastructure for all engineers to contribute to OpenJDK with.My home in all of this was the BOF rooms and the sessions there meeting the JUG leaders, talking about OpenJDK infrastructure and celebrating the Duchess Duke Award together with the others. The restaurants in the area was slower than I've ever seen, so I missed out on Trisha Gee's brilliant replay of the workshop "The Problem with Women in IT - an Agile Approach" where she masterly leads the audience (a packed room, 50-50 gender distribution) to solve the problem of including more diversity in the developer community. A tough and sometimes sensitive topic where she manages to keep the discussion objective with a focus of improving the matter from a business perspective. Mattias Karlsson is organizing the Java developer conference Jfokus in Stockholm and was there talking to Andres Almires planning a Hackergarten with a possible inclusion of an OpenJDK bugathon. That would be really cool, especially as the Oracle Stockholm Java development office is just across the water from the Jfokus venue, some of the local JVM engineers will likely attend and assist, even though the bug smashing theme will likely be more starter level build warnings in Swing or langtools than fixing JVM bugs.I was really happy that I managed to catch a seat for the Java Posse live podcast "the Third Presidential Debate" a lot of nerd humor, a lot of beer, a lot of fun :) The new member Chet had a perfect dead pan delivery and now I just have to listen more to the podcasts! Can't get the most perfect joke out of my head, talking about beer "As my father always said: Better a bottle in front of me than a frontal lobotomy" - hilarious :)I attended the sessions delivered by my Stockholm office colleagues Marcus Lagergren (on dynamic languages on the jvm, JavaScript in particular) and Joel Borggrén-Franck (Annotations) and was happy to see the packed room and all the questions raised at the end.There's loads of stuff to write about the event, but just have to pace myself for now. It was a fantastic event, captain Stephan Janssen with crew should be really proud to provide this forum to the developer community!

The call for papers begins  on December 1st for Devoxx in London and Paris.  Speakers will be able to present at the two  conferences in the same week. Oracle committed  to fully sponsor the three Devoxx conferences in  2013 with a platinum sponsorship. Over 5,000 developers are expected to attend those conferences. Five dancing NAO robots welcomed attendees at the keynote. Stephan Janssen offers the JUGs to replicate Devoxx4kids workshops using his content and web infrastructure.  He recommended organizing kid events because “the workshops were really fun and such rewarding experience.” Stephan also announced the redesign of Parleys with Html 5 and GlassFish. Friendlier to speakers, they will be able to post their slides online before their talks and then sync the talk's sound track with the slides. Nandini Ramani, VP of product development explained in her keynote address the growing role of Java from enterprise application development to cloud computing to embedded machine-to-machines systems. “Java continues to drive the applications and devices that enrich our interactivity with the world around us” she said. The Java platform has expanded its reach with the OS X and Linux ARM support on Java SE and with two new releases, Java SE embedded and Java embedded Suite 7.0 middleware platform.  Coming up next year is JDK 8, which will include Project Lambda, Project Nashorn and more. As part of that release, JavaFX will offer 3D and third-party component integration. At Devoxx, the slick and interactive schedules were designed with JavaFX. The earliest version of the Java EE 7 SDK is available for download and has WebSocket support, improved JSON support and more.  Stephen Chin arrived on stage with his bike, ending his European NightHacking tour.

  • JavaOne: Parleys.com, Spring Vs. Java EE and HTML5 tooling

    - by delabassee
    Parleys.com, a 2012 Duke's Choice Award winner, is an E-Learning platform that host content from different sources (conferences, JUGs meetings, etc.). There is a lot of technical content available for online but also offline consumption, including many sessions on Java EE. Parleys has just released, for free, all the Devoxx 2011 sessions (video and slides sync'ed!). From a technical point of view, Parleys.com is interesting as they have switched from Spring to Java EE 6 to avoid being locked in a proprietary framework. During the GlassFish Community BoF, Stephan Janssen (Parleys.com and Devoxx founder) also presented how GlassFish is used to support 2000 concurrent Parleys users over a cluster of 2 GlassFish instances. Talking about Java EE and/or Spring, Harshad Oak has posted an update on the 'Spring Vs. Java EE' panel discussion that took place on Tuesday. As Arun said standards such as Java EE does not necessarily refrain innovation: "JBoss Forge & Arquillian from RedHat are great examples of innovation in the JavaEE community. Standardization is important but innovation does continue even within that framework." Simplicity, productivity along with HTML5 are the driving themes of Java EE 7. In terms of simplicity and productivity, the developer experience can also be improved by the tooling. Every NetBeans release comes with a large set of improvements, the just released NetBeans 7.3 beta is no exception. The goal of ‘NB 7.3’s Project Easel’ is to improve HTML5 development, something that will be handy for Java EE 7 developers. Project Easel can, for example, communicate directly to Chrome's WebKit engine, this feature was shown during Sunday's Technical Keynote at the end of the Java EE section. In this beta release, Chrome and the embedded JavaFX browser are the only supported browsers but the NetBeans team plan to add support, over time, for other WebKit based browsers. NetBans 7.3 beta NetBeans 7.3 screenscasts Today (i.e. Wednesday 3rd) is also the final exhibition day, so make sure to visit the Java EE and the GlassFish pods on the Java DEMOgrounds (Hilton Grand Ballroom, 9:30 am - 5:00 pm). Finally, here are some Java EE and GlassFish related activities worth attending today if you are at JavaOne : Wednesday October 3rd Time Title Location 8:30-9:30am What's New in Servlet 3.1: An Overview Parc 55 Mission 8:30-9:30am Bean Validation 1.1: What's New Under the Hood Parc 55Cyril Magnin II/III 10:00-11:00am JSR 353: Java API for JSON Processing Parc 55 Mission 10:00-12:00pm Tutorial : Integrating Your Service into the GlassFish PaaS Platform Parc 55 Devisidero 11:30-12:30pm What's New in JSF: A Complete Tour of JSF 2.2 Parc 55Cyril Magnin I 11:30-12:30pm Best of Both Worlds: Java Persistence with NoSQL and SQL Parc 55 Mission 1:00-2:00pm Sharding Middleware to Achieve Elasticity and High Availability in the Cloud Parc 55Market Street 1:00-2:00pm Pimp My RESTful Java Applications Parc 55Cyril Magnin I 3:00-4:00pm Migrating Spring to Java EE Parc 55Cyril Magnin II/III 4:30-5:30pm JavaEE.Next(): Java EE 7, 8, and Beyond Parc 55Cyril Magnin II/III 4:30-5:30pm HTML5 WebSocket and Java Parc 55Cyril Magnin I 4:30-5:30pm Easy Middleware for Your Embedded Device Nikko Ballroom II/III

  • JavaOne Tutorial Report - JavaFX 2 – A Java Developer’s Guide

    - by Janice J. Heiss
    Oracle Java Technology Evangelist Stephen Chin and Independent Consultant Peter Pilgrim presented a tutorial session intended to help developers get a handle on JavaFX 2. Stephen Chin, a Java Champion, is co-author of the Pro JavaFX Platform 2, while Java Champion Peter Pilgrim is an independent consultant who works out of London.NightHacking with Stephen ChinBefore discussing the tutorial, a note about Chin’s “NightHacking Tour,” wherein from 10/29/12 to 11/11/12, he will be traveling across Europe via motorcycle stopping at JUGs and interviewing Java developers and offering live video streaming of the journey. As he says, “Along the way, I will visit user groups, interviewing interesting folks, and hack on open source projects. The last stop will be the Devoxx conference in Belgium.”It’s a dirty job but someone’s got to do it. His trip will take him from the UK through the Netherlands, Germany, Switzerland, Italy, France, and finally to Devoxx in Belgium. He has interviews lined up with Ben Evans, Trisha Gee, Stephen Coulebourne, Martijn Verburg, Simon Ritter, Bert Ertman, Tony Epple, Adam Bien, Michael Hutterman, Sven Reimers, Andres Almiray, Gerrit Grunewald, Bertrand Boetzmann, Luc Duponcheel, Stephen Janssen, Cheryl Miller, and Andrew Phillips. If you expect to be in Chin’s vicinity at the end of October and in early November, by all means get in touch with him at his site and add your perspective. The more the merrier! Taking the JavaFX PlungeNow to the business at hand. The “JavaFX 2 – A Java Developer’s Guide” tutorial introduced Java developers to the JavaFX 2 platform from the perspective of seasoned Java developers. It demonstrated the breadth of the JavaFX APIs through examples that are built out in the course of the session in an effort to present the basic requirements in using JavaFX to build rich internet applications. Chin began with a quote from Oracle’s Christopher Oliver, the creator of F3, the original version of JavaFX, on the importance of GUIs:“At the end of the day, on the one hand we have computer systems, and on the other, people. Connecting them together, and allowing people to interact with computer systems in a compelling way, requires graphical user interfaces.”Chin explained that JavaFX is about producing an immersive application experience that involves cross-platform animation, video and charting. It can integrate Java, JavaScript and HTML in the same application. The new graphics stack takes advantage of hardware acceleration for 2D and 3D applications. In addition, we can integrate Swing applications using JFXPanel.He reminded attendees that they were building JavaFX apps using pure Java APIs that included builders for declarative construction; in addition, alternative languages can be used for simpler UI creation. In addition, developers can call upon alternative languages such as GroovyFX, ScalaFX and Visage, if they want simpler UI creation. He presented the fundamentals of JavaFX 2.0: properties, lists and binding and then explored primitive, object and FX list collection properties. Properties in JavaFX are observable, lazy and type safe. He then provided an example of property declaration in code.  Pilgrim and Chin explained the architectural structure of JavaFX 2 and its basic properties:JavaFX 2.0 properties – Primitive, Object, and FX List Collection properties. * Primitive Properties* Object Properties* FX List Collection Properties* Properties are:– Observable– Lazy– Type SafeChin and Pilgrim then took attendees through several participatory demos and got deep into the weeds of the code for the two-hour session. At the end, everyone knew a lot more about the inner workings of JavaFX 2.0.

Oracle fully supports "Devoxx UK" and "Devoxx France" as a European Platinum Partner. Submit proposals and participate in both conferences since they are a two-hour train ride away from one another. The Devoxx conferences are designed “for developers by developers.” The conference committees are looking for speakers who are passionate developers unafraid to share their knowledge of Java, mobile, web and beyond. The sessions are about frameworks, tools and development with in-depth conference sessions, short practical quickies, and bird-of-a-feather discussions. Those different formats allow speakers to choose the best way to present their topics and can be mentioned during the submission process Devoxx has proven its success under Stephan Janssen, organizer of Devoxx in Belgium for the past 11 years. Devoxx has been the biggest Java conference in Europe for many years. To organize those local conferences, Stephan has enrolled the top community leaders in the UK and France. Ben Evans and Martijn Verberg are the leaders of London Java User Group (JUG) and are also known internationally for starting the Adopt-a-JSR program. Antonio Goncalves is the leader of the Paris JUG. He organized last year’s Devoxx France, which was a big success with twice the size first expected. The organizers made sure to add the local character to the conferences. "The community energy has to feel right," said Ben Evans and for that he picked an "old Victoria hall" for the venue. Those leaders are part of very dynamic Java communities in France and in the UK. France has 22 JUGs; the Paris JUG alone has 2,000 members. The UK has over 50,000 developers working in London and its surroundings; a lot of them are Java developers working in the financial industry. The conference fee is kept as low as possible to encourage those developers to attend. Devoxx promises to be crowded and sold out in advance. Make sure to submit your talks to both Devoxx UK and France before January 31st, 2013.

  • Adjust static value into dynamic (javascript) value possible in Sharepoint allitems.aspx page?

    - by lerac
    <SharePoint:SPDataSource runat="server" IncludeHidden="true" SelectCommand="&lt;View&gt;&lt;Query&gt;&lt;OrderBy&gt;&lt;FieldRef Name=&quot;EventDate&quot;/&gt;&lt;/OrderBy&gt;&lt;Where&gt;&lt;Contains&gt;&lt;FieldRef Name=&quot;lawyer_x0020_1&quot;/&gt;&lt;Value Type=&quot;Note&quot;&gt;F. Sanches&lt;/Value&gt;&lt;/Contains&gt;&lt;/Where&gt;&lt;/Query&gt;&lt;/View&gt;" id="datasource1" DataSourceMode="List" UseInternalName="true"><InsertParameters><asp:Parameter DefaultValue="{ANUMBER}" Name="ListID"></asp:Parameter> This codeline is just one line of the allitems.aspx of a sharepoint list item. It only displays items where lawyer 1 = F. Sanches. Before I start messing around with the .ASPX page I wonder if it possible to change F. Sanches (in the code) into a dynamical variable (from a javascript value or something else that can be used to place the javascript value in there dynamically). If I put any javascript code in the line it will not work. P.S. Ignore ANUMBER part in code. Let say to make it simple I have javascript variable like this (now static but with my other code it is dynamic). It would be an achievement if it would place a static javascript variable. <SCRIPT type=text/javascript>javaVAR = "P. Janssen";</script> If Yes -- how? If No -- Thank you!
