  • Tool for checking source for dependencies on specific Java versions

    - by Gregor
    Is there a quick way (e.g. tool) to detect, from the source (or maybe even from compiled classes), which parts of an application call Java API methods that are only implemented in a specific Java version? (e.g. which parts of my app are Java6-specific) I don't necessarily want to hop through all ClassMismatchErrors and avoid the trial-and-error-method. Let's say I only want to document which parts of an application won't work if they were writte for, e.g., Java6 and I want to run it in a version 5 JDK. Is there something like this? Google did not help this time, nor did I find any solution here (a rare case indeed:)

  • Will using a VCS help me as a web dev?

    - by jsims281
    I'm thinking of trying a VCS such as subversion, to manage my next project, but I'm not sure if will offer any real benefits for me as a web developer. As I understand it, one of the major benefits of a VCS is that a group of people can work on a project at once. Reading material on the subject seems pretty one sided: "Using a version control system is an absolute must for a developer of a project above a few hundred lines of code" ...and I've got a feeling it could become a chore, with not many benefits. I work on development server on the local network, so any amount of people can work on the files already. If anyone needs to get in remotely, they use FTP. What would a modern version control system give me on top of this?

  • Using SVN alone or in small workgroups - workflow approach?

    - by Industrial
    Hi everybody, I have spent some months working on a web application and we're come close to production stage. It's soon time to expand the development group with 1-3 people on this project. I have not too much experience on working with SVN, but It's obviously the choice for a big part of the larger companies out there, so I am guessing that the pros of SVN without a doubt outweights the time spent on commit/check ins / check outs etc. The workflow seems to become a bit more complicated with SVN, and even though I have read Version Control with Subversion by O'Reilly Media and I am not sure yet if it's overkill to use SVN for any reasons besides backup when developing alone or in a small (1-3 people) workgroup? How do you do it? What's your workflow with version control while working alone or in small workgroups? Thanks!

  • Multiple repositories or single repository with branches?

    - by Goro
    I have been working on a project for some time, and it has branched off into several different versions. All versions have some common code base, and each version has specific functionality that is unique, and each version will need to be supported individually. What SVN structure would you recommend? Right now I am using a separate repository for each project, but the downside of that is that it is impractical for large number of products. The downside of using a single repository with branches is that it would add revision numbers to every branch whether anything was committed, regardless from which branch. What setup do you/would you use in this situation?

  • Grails + GAE - Issue using app.servlet.version=2.5

  • Android SQLite database locale, locking, and version

    - by gdoten
    In some books and online I see these method calls being made after a database is created: db.setLocale(Locale.getDefault()); db.setLockingEnabled(true); db.setVersion(DB_VERSION); Why is this done? As far as I can tell, after creating a new database, the system adds a table named android_metadata with one field named locale and that table has one row with the locale field set to "en_US". Now I assume the column has that value because I am using a U.S. phone, and if I were using a phone from a different region then the locale field would be set appropriately. Can anyone confirm this? I'm guessing that the setLocale method would only be useful in the case that you install a pre-built database onto a phone and then want to change the locale to match the phone's locale. Sound right? The documentation for setLockingEnabled says it defaults to true so there's no need to make that call, right? Lastly, what's with the call to setVersion? I can't find a table that contains this information so I've been assuming that the database file itself stores the version number somewhere. So when I create a database, which requires you to have already specified the version number in the call to the SQLiteOpenHelper constructor, there's no point in calling setVersion. Again, perhaps this method exists for the case of installing a pre-built database to a device and you then wish to change the database's version (though I can't think of when doing this would make sense). Thanks for any insight!

  • Adobe Air update error "file version doesn't match" but it's the same!...

    - by baroquedub
    I'm using Claus Wahlers' AIR Remote Updater class (codeazur.com.br/lab/airremoteupdater/). All works fine and an update is triggered if the remote version is newer. The newer file is downloaded and the update starts. However I then get "an error has occured" message: "This application cannot be installed because this installer has been mis-configured" (The same file will update without errors when run manually "Would you like to replace the currently installed version?" Choosing 'replace' works fine) I have enabled Air Application Installer logging and I can see that both the app id and the pub id match - this seems to be a common reason for this problem (forums.adobe.com/thread/243421?tstart=60) The error given in the log file is as follows: AIR file version doesn't match Requested version: ; AIR file version: 1.0.2 But if I unzip the new app file and look at META-INF\AIR\application.xml the version designator shows <version>1.0.2</version> As requested! The log file is also showing me where the newer file is being downloaded and unpacked. If I look at the application.xml file in that directory: Unpackaging to C:\Documents and Settings\myusername\Local Settings\Temp\fla893D.tmp the version designator also shows <version>1.0.2</version> I don't get it?! The log tells me that the requested file version doesn't match but it's exactly the same as what's shown in the version designator of the downloaded update package... This is driving me crazy. Can anyone help?

  • SVN Version Rollback Question

    - by phimuemue
    Hello, I'm using SVN (TortoiseSVN) and often came into the following situation: I wanted to discard any changes since a specific (old) revision and turn all files back to this specific (old) version. Then I wanted to work further as if this specific (old) revision was the newest one, i.e. I wanted to be able to commit the specific old revision as a new revision. I found several solutions for this problem (for example stackoverflow.com/questions/402159/roll-back-or-revert-entire-svn-repository-to-an-older-revision or rustyrazorblade.com/2007/04/how-to-roll-back-commits-to-an-earlier-version-of-a-repository-in-svn/). However, I wonder if there is a simple way to roll back to a specific revision. I thought version control is just good for such things (or am I misunderstanding something?). Is there a simple command/button/etc. that takes an updates my local repository to an old revision and declares it to be the newest one? Since I suppose that there is no "built-in" function to do this, I wanted to know what reason lead the developers to the decision not to integrate this feature. Does anybody know this?

  • URL path changes between dev and published version

    - by Bob Horn
    I just got Scott Hanselman's chat app with SignalR working with ASP.NET MVC 4. After hours of configuration, trial and error, and getting different versions of Windows to talk to each other on my home network, it's all working except that I'm left with one issue that I'm not sure how to handle. This line of javascript has to change, depending on if I'm running the app through Visual Studio or the published (IIS) version: Works when running within VS: var connection = $.connection('echo'); Works with published version: var connection = $.connection('ChatWithSignalR/echo'); When I run within VS, the URL is: http://localhost:9145/ And the published version is: http://localhost/ChatWithSignalR If I don't change that line of code, and try to run the app within VS, using the javascript that has ChatWithSignalR in it, I get an error like this: Failed to load resource: the server responded with a status of 404 (Not Found) http://localhost:9145/ChatWithSignalR/echo/negotiate?_=1347809290826 What can I do so that I can use the same javascript code and have it work in both scenarios? var connection = $.connection('??????'); Note, this is in my Global.asax.cs: RouteTable.Routes.MapConnection<MyConnection>("echo", "echo/{*operation}");

  • OpenVPN access server on Amazon VPC vs free version

    - by imaginative
    Maybe I'm missing the point, but I'd like to setup simple VPN access with software VPN to access my private network on Amazon VPC. I thought OpenVPN would be a great solution for this, and I thought it might make sense to put this on the NAT instance that comes with VPC so I don't have to spend money on another instance. Is there any advantage to running the following: http://www.openvpn.net/index.php?option=com_content&id=493 vs sticking to the free solution of OpenVPN? What does one offer over the other? Any reason not to run this on the NAT instance itself?

  • Since updating to today's version of Skype on Win8, Skype won't even log in

    - by Warren P
    I am using the desktop (win32 not appstore) Skype on Windows 8. I accepted an auto-update today which now will not let me log into skype at all. I wiped out the AppData\Roaming\Skype folder because that's how you get Skype back in the past when it has gone stupid, but that didn't help either. I do not get any error message, just the circular progress indicator that lasts forever. (Okay, so far it's been 30 minutes. It may eventually time out yet.) Other ideas please? I tried the Windows 8 App Store Skype app (WinRT), which I hate, I guess I'll go back and install that for now. Update Skype 6.0.126 seems to be completely broken on my Win8 machine.

  • Git version control with multiple users

    - by ignatius
    Hello, i am a little bit lost with this issue, let me explain you my problem: I want to setup a git repository, three of four users will contribute, so they need to download the code and shall be able to upload their changes to the server or update their branch with the latest modifications. So, i setup a linux machine, install git, setup the repository, then add the users in order to enable the acces throught ssh. Now my question is, What's next?, the git documentation is a little bit confusing, i.e. when i try from a dummy user account to clone the repository i got: xxx@xxx-desktop:~/Documentos/git/test$ git clone -v ssh://[email protected]/pub.git Initialized empty Git repository in /home/xxx/Documentos/git/test/pub/.git/ [email protected]'s password: fatal: '/pub.git' does not appear to be a git repository fatal: The remote end hung up unexpectedly is that a problem of privileges? need any special configuration? i want to avoid using git-daemon or gitosis, sorry, maybe my question sound silly but git is powerfull but i admit not so user friendly. Thanks Br

  • PC version of Google Chrome doesn't recognize ".local" domain name

    With Bonjour installed in PC, I can access my server in Mac with ".local". For example, I can access my mac with the name "prosseek.local". The problem is that in Chrome for PC, it doesn't recognize "local" to open search page instead of accessing mac server. This issue isn't happening with other web browsers (explore/firefox) in PC. What is even wierder is that chrome seems to recognize the ".local" sometimes, but not always. How to solve this issue? Or, how can I teach chrome that ".local" is a part of page name in order not to direct to search page?
