• Java EE and GlassFish Server Roadmap Update

  - by John Clingan

  2013 has been a stellar year for both the Java EE and GlassFish Server communities. On June 12, Oracle and its partners announced the release of Java EE 7, which delivers on three major themes – HTML5, developer productivity, and meeting enterprise demands. The online event attracted over 10,000 views in the first two days! During the online event, Oracle also announced the availability of GlassFish Server Open Source Edition 4, the world's first Java EE 7 compatible application server. The primary role of GlassFish Server Open Source Edition has been, and continues to be, driving adoption of the latest release of the Java Platform, Enterprise Edition. Oracle also announced the Java EE 7 SDK, which bundles GlassFish Server Open Source Edition 4, as a Java EE 7 learning aid. Last, Oracle publicly announced the Java EE 7 reference implementation based on GlassFish Server Open Source Edition 4. Java EE is a popular platform, as evidenced by the 20+ Java EE 6 compatible implementations available to choose from. After the launch of Java EE 7 and GlassFish Server Open Source Edition 4, we began planning the Java EE 8 roadmap, which was covered during the JavaOne Strategy Keynote. To summarize, there is a lot of interest in improving on HTML5 support, Cloud, and investigating NoSQL support. We received a lot of great feedback from the community and customers on what they would like to see in Java EE 8. As we approached JavaOne 2013, we started planning the GlassFish Server roadmap. What we announced at JavaOne was that GlassFish Server Open Source Edition 4.1 is scheduled for 2014. Here is an update to that roadmap. GlassFish Server Open Source Edition 4.1 is scheduled for 2014 We are planning updates as needed to GlassFish Server Open Source Edition, which is commercially unsupported As we head towards Java EE 8: The trunk will eventually transition to GlassFish Server Open Source Edition 5 as a Java EE 8 implementation The Java EE 8 Reference Implementation will be derived from GlassFish Server Open Source Edition 5. This replicates what has been done in past Java EE and GlassFish Server releases. Oracle will no longer release future major releases of Oracle GlassFish Server with commercial support – specifically Oracle GlassFish Server 4.x with commercial Java EE 7 support will not be released. Commercial Java EE 7 support will be provided from WebLogic Server. Oracle GlassFish Server will not be releasing a 4.x commercial version Expanding on that last bullet, new and existing Oracle GlassFish Server 2.1.x and 3.1.x commercial customers will continue to be supported according to the Oracle Lifetime Support Policy. Oracle recommends that existing commercial Oracle GlassFish Server customers begin planning to move to Oracle WebLogic Server, which is a natural technical and license migration path forward: Applications developed to Java EE standards can be deployed to both GlassFish Server and Oracle WebLogic Server GlassFish Server and Oracle WebLogic Server have implementation-specific deployment descriptor interoperability (here and here). GlassFish Server 3.x and Oracle WebLogic Server share quite a bit of code, so there are quite a bit of configuration and (extended) feature similarities. Shared code includes JPA, JAX-RS, WebSockets (pre JSR 356 in both cases), CDI, Bean Validation, JAX-WS, JAXB, and WS-AT. Both Oracle GlassFish Server 3.x and Oracle WebLogic Server 12c support Oracle Access Manager, Oracle Coherence, Oracle Directory Server, Oracle Virtual Directory, Oracle Database, Oracle Enterprise Manager and are entitled to support for the underlying Oracle JDK. To summarize, Oracle is committed to the future of Java EE.  Java EE 7 has been released and planning for Java EE 8 has begun. GlassFish Server Open Source Edition continues to be the strategic foundation for Java EE reference implementation going forward. And for developers, updates will be delivered as needed to continue to deliver a great developer experience for GlassFish Server Open Source Edition. We are planning for GlassFish Server Open Source Edition 5 as the foundation for the Java EE 8 reference implementation, as well as bundling GlassFish Server Open Source Edition 5 in a Java EE 8 SDK, which is the most popular distribution of GlassFish. This will allow GlassFish releases to be more focused on the Java EE platform and community-driven requirements. We continue to encourage community contributions, bug reports, participation on the GlassFish forum, etc. Going forward, Oracle WebLogic Server will be the single strategic commercially supported application server from Oracle.

• ubuntu cobbler server - importing distros

  - by Stu2000

  I setup and fully configured ubuntu-12.04-server machine with cobbler/dhcp running in about 10 minutes (compared to taking over an hour on centos 5.8). I discovered the cobbler import which appears to be useful. Does this remove the need to use a cobbler distro add? whenever I run a cobbler report after a successful import of ubuntu desktop iso: sudo cobbler import --name=Ubuntu --path=/mnt --breed=debian task started: 2012-12-13_163245_import task started (id=Media import, time=Thu Dec 13 16:32:45 2012) Found a debian/ubuntu compatible signature: pool adding distros avoiding symlink loop avoiding symlink loop avoiding symlink loop associating repos associating kickstarts *** TASK COMPLETE *** I just get the following (nothing): distros: ========== profiles: ========== systems: ========== repos: ========== images: ========== mgmtclasses: ========== packages: ========== files: ========== I was rather hoping that I wouldn't have to do the traditional copying of all files in /mnt to a new /distro directory and then perform a cobbler distro add --initrd=/path/to/inird --kernel=/path/to/kernel Maybe I am mistaken about what the import actually does for me. If someone could elaborate on what the import is actually for please do.

• Gnome Classic U 11.04 trash not working, can't find my trash dir

  - by Bruce Salem

  I did an upgrade from U 10.10 to U 11.04. I can't upgrade further because Upgrade Manager says that there are unsupported packages. How do I find them? A more immediate problem is that trash stopped working even though "/.share/local/Trash is getting files removed by the file manager. The trash icon on the lower panel fails after having done the upgrade from Gnome 2 to Unity and using Gnome Classic, says "No Such File or Directory". File Operations says it is looking at "/". How do I reconfigure the trash icon to use my local trash dir? The trash dir is there, has the right permissons, I can "rm" the dir tree there, and recreate it by moving files to the trash from the file manager.

• How do I make Powertop changes permanent?

  - by arno

  I'm on a Compaq 615 and it's fan is loud as hell. Not much you can do about that but I'm trying to keep the CPU/GPU as cool as possible. This is what Powertop has to say: If I change all of them to "good", the changes don't survive a reboot. Also, upon exiting Powertop I get this: Loaded 8 prior measurements Cannot load from file /var/cache/powertop/saved_parameters.powertop Leaving PowerTOP I added the line to the "grub"-file as suggested here Upon closing gedit I get this: (gedit:2728): Gtk-WARNING **: Attempting to store changes into `/root/.local/share/recently-used.xbel', but failed: Datei »/root/.local/share/recently-used.xbel.9CIMAW« konnte nicht angelegt werden: Datei oder Verzeichnis nicht gefunden The part in German says: Couldn't be created: File or directory not found.

• Is there any new method for link-backs [on hold]

  - by Mir Hammad

  As all SEOs know that google is trying its very best to kill SEO and linkbacks are quite a difficult task now. Although content is the key but my boss is still possessed with linkbacks. I can not do directory posting, link exchange, paid linking, web 2.0 and blog commenting as they are spam now. I do not see what other choice i have except forum posting and article posting. Can someone suggest new method to acquire link backs ? I know almost all traditional methods so don't say press release or etc. If you really have something out of the box or not very much common please share.

• How to use Mercurial's LargeFiles extension? [migrated]

  - by DuncanBoehle

  I use Mercurial for game development, and I'm trying to use the LargeFiles extension included in Mercurial 2.0 to keep track of large binary assets. Unfortunately there isn't a whole lot of documentation on the extension, so I'm not sure how people are expected to use it. For example, is there any way to safely clean out the .hg/largefiles directory? If I'm on the tip revision, and expect to always have internet access, then I don't need the old versions of largefiles cluttering up the repository, since that's the whole point of using the LargeFiles extension. Also, how do I have more fine-grained control over where the largefile store is? I can only assume that it's created somewhere on the computer that ran hg init, but I have no idea about the details. Thanks!

• AWStats: cannot access /var/log/apache2/access.log

  - by Joril

  I installed awstats on my new Ubuntu Lucid server, but when cron tries to run it as user www-data, it complains that cannot access /var/log/apache2/access.log: Permission denied. In /usr/share/doc/awstats/README.Debian there's this paragraph: By default Apache stores (since version 1.3.22-1) logfiles with uid=root and gid=adm, so you need to either... 1) Change the rights of the logfiles in /etc/logrotate.d/apache so that www-data has at least read access. 2) As 1) but change to a specific user, and use the suEXEC feature of Apache to run as same user (and either change the right of /var/lib/awstats as well or use another directory). This is more complicated, but then the logs are not generally accessible to the server (which was probably the point of the Apache default). 3) Change awstats.pl to group adm (but beware that you are then taking the risk of allowing a CGI-script access to admin stuff on the machine!). I'd go with 1, but what are the recommended permissions to grant?

• problem using pydoc in python

  - by rohanag

  I'm using pydoc in python 2.7.3 to generate documentation for a file called PreProcessingAPI.py which contains a class called PreProcessingAPI In PreProcessingAPI.py, I have the following import in the beginning of the file: from __future__ import division from re import * from nltk.stem import porter The problem is, in the documentation generated by pydoc, nltk.stem.porter is shown as a Module. There is also a DATA heading with all sorts of variables I do not know about. Is there a way to avoid these variables and avoid showing nltk.stem.porter in the modules? I'm running the following command to generate documentation python pydoc.py -w PreProcessingAPI.py I've put the file pydoc.py in the directory containing my file. Here is the file generated: https://www.dropbox.com/s/4rb6ut99o25mwly/PreProcessingAPI.html

• How to download flash (streaming) videos from sites like youtube, dailymotion, vimeo, etc.?

  - by riclags

  I have read this thread but please hear me out. I use Ubuntu 10.04 LTS (32-bit) and I didn't bother to install the Flash plugin for Firefox as I am using a netbook and sometimes Flash caused firefox to crash. What I would like to ask is if I had the link to the video, is there some way I can download it and watch it offline (via VLC) so that I don't need to install Flash plugin? Command line or GUI techniques is welcome. Based on what I have read, using the /tmp technique requires Flash plugin to be installed and the video to be loaded before I can go scavenge it in the said directory. Note that I also want to dload videos from site aside from youtube.

• Is SimplePHPBlog a secure blogging engine?

  - by authentictech

  Has anyone used the blog engine SimplePHPBlog? It is a simple blog engine that uses only text files (no database). My problem with it is that the content directory where the texts files are stored appears to require being world writeable/readable (i.e. permission 777) for it to work. This means anyone can access the text files with a browser! These text files include the blog/comment poster's IP and email address! This is not secure or good practice, right?

• Fiddler Inspector for Federation Messages

  - by Your DisplayName here!

  Fiddler is a very useful tool for troubleshooting all kinds of HTTP(s) communications. It also features various extensibility points to make it even more useful. Using the inspector extensibility mechanism, I quickly knocked up an inspector for typical federation messages (thanks for Eric Lawrence btw). Below is a screenshot for WS-Federation. I also added support for SAML 2.0p request/response messages: The inspector can be downloaded from the identitymodel Codeplex site. Simply copy the binary to the inspector folder in the Fiddler directory.

• Proper way to create and work with a subdomain?

  - by Genadinik

  My site got effected by Panda, and I am trying to see if making a subdomain would work. The site is comehike.com, and I created a subdomain which is currently empty at hiking.comehike.com I have a directory /outdoors that has some high quality hand-written articles. I want to put those into the new subdomain to see what would happen. My questions are: Should I just copy and paste the files for those pages into the new subdomain's folder, and just change all the links in all my pages from the original domain to the new subdomain? Should I just do a 301 redirect to the new subdomain? Since test.site.com and www.site.com are different domains, will the new page have to start from scratch in terms of Pagerank, and its rankings in the SERPs?

• Best S.E.O. practice for backlinking etc

  - by Aaron Lee

  I'm currently working on a website that I am really looking to optimise in terms of search engines, i've been submitting between 5-20 directory submissions daily, i've validated and optimised my code and i've joined a lot of forums etc to speak of the website in question, however, I don't seem to be making much of an impact in terms of Google. I know that S.E.O. takes a while to start making an impact, and that Google prefers sites that a regularly updated and aged, but are there any more practices that can really help with organic results in Search engines. I have looked on Google itself, and a few other SE's but nobody is willing to talk about extensive S.E.O. practices as they normally don't want people knowing their formula's for S.E.O., also does anyone know of a decent piece of software that really looks into the in's and out's of your page and provides feedback, I usually use http://www.woorank.com, but only using one program doesn't show if it's exactly correct in what it's saying. If anyone could help it would be much appreciated, thank you very much.

• How is ~/bin added to my path?

  - by Hari Sundararajan

  I have not added ~/bin to any of my .bash* files. However, $PATH does list that directory. The reason I am asking this in the Ubuntu specific StackExchange is because, well, I have exactly the same .bashrc, .bash_profile and .bash_aliases in both Fedora and Ubuntu machines (in fact, I have them on Dropbox and symlinked in ~) and in my Fedora machines, ~/bin is not added. In other words, if I add ~/bin to my path by making an entry in .bashrc, it shows up once on Fedora and twice on Ubuntu. Where is ~/bin being added to my path?

• Methods of Geotargeting and optimising for location

  - by Switchfire

  This is somewhat an SEO question and somewhat a general web developer question. Our company website is pretty awful, I'm currently redesigning the new one, the problem is they have a directory called regions, which contains page for around 200 different locations around the country, all stuffed to the brim with keywords and useless things. Some of these pages work and the traffic's good enough to keep a few of them. Apart from creating a page for everyone again, is there another way of targeting all these locations without having to create a new page for each or is the a more dynamic way to do it? Any ideas or suggestions?

• Can third party content on sub-domains harm the main site's search rankings?

  - by dror

  I have a site that is a "portal" or "directory" for service providers. We opened every service provider's own page on our site, but now we get a lot of applications from those providers that want sites from their own. We want to make a full site for every service provider, but rather put them on sub domain URLs. (They don’t mind, it's OK for them.) So, my site is www.exaple.com Their site will be: provider.example.com Now I have two questions: Can the content on the provider sites harm my site in SEO? If one from those sub domains is punished by Google because the owner does "black hat SEO", how it will affect the rood domain? Can it make the root domain get punished?

Also why do I have to always do it 777, I tried 755 for folders and 644 for files, but that won't work.

• How to ensure apache2 reads htaccess for custom expiry?

  - by tzot

  I have a site with Apache 2.2.22 . I have enabled the mod-expires and mod-headers modules seemingly correctly: $ apachectl -t -D DUMP_MODULES … expires_module (shared) headers_module (shared) … Settings include: ExpiresActive On ExpiresDefault "access plus 10 minutes" ExpiresByType application/xml "access plus 1 minute" Checking the headers of requests, I see that max-age is set correctly both for the generic case and for xml files (which are auto-generated, but mostly static). I would like to have different expiries for xml files in a directory (e.g. /data), so http://site/data/sample.xml expires 24 hours later. I enter the following in data/.htaccess: ExpiresByType application/xml "access plus 24 hours" Header set Cache-control "max-age=86400, public" but it seems that apache ignores this. How can I ensure apache2 uses the .htaccess directives? I can provide further information if requested.

• home-folder encryption: Does it work?

  - by jpaugh

  Back when Ubuntu first sported home folder encryption (what, around the time of Jaunty Jackalope?), I opted in. That caused me some grief when I decided to change my login password. I found that I couldn't decrypt my home anymore! In trying to fix this, I eventually muddled things to the point that using my old password didn't work anymore, either. That experience has left me very shy of using an encrypted home directory--nevermind the performance hit of encryption. Has this feature become more "stable" since it came out? Does it break if you change your login password? Has your [more recent] experience been better? (Does it work in Natty Narwhal?)

• How to install Visual Python?

  - by user214152

  I'm a Linux newbie but I'm determined to get my favorite applications on my laptop running Ubuntu 12.04. I just installed Cinnamon. I'm trying to install Visual Python and it requires Python 2.7. I followed the instructions on the VPython site but the Wine application isn't extracting anything from the Python .msi file. From the first line wine start /i python-2.7.5.amd64.msi /qn TARGETDIR=~/Python27 ALLUSERS=1 it says fixme:storage:create_storagefile Storage share mode not implemented. I created that Python27 directory so I know it exists and it's empty. I know Ubuntu already has Python 2.7 so I just tried running the VPython.exe file but it says "This program can only be installed on versions of Windows designed for the following processor architectures: x64." My Toshiba satellite has a 64-bit processor. Could anybody help?
