  • SecurityException when accessing (ejb2-) session bean via local interface in JBoss 5

    - by sme
    I have the following problem with an EJB 2 SessionBean when deploying in JBoss 5: The SessionBean (called LVSKeepAliveDispatcher) requires a specific user role (called "LVSUser"), specified by <method-permission > <description></description> <role-name>LVSUser</role-name> <method > <description></description> <ejb-name>LVSKeepAliveDispatcher</ejb-name> <method-name>*</method-name> </method> </method-permission> in ejb-jar.xml. I now want to access this SessionBean from a Service (i.e. a class implementing the org.jboss.varia.scheduler.Schedulable interface that is then registered as a service) running inside the same JBoss instance. This is my jboss-service.xml: <server> <mbean code="org.jboss.varia.scheduler.Scheduler" name="lvs:service=TranslationService"> <attribute name="StartAtStartup">true</attribute> <attribute name="SchedulableClass">de.repower.lvs.server.service.translation.TranslationService</attribute> <attribute name="SchedulableArguments"></attribute> <attribute name="SchedulableArgumentTypes"></attribute> <attribute name="InitialStartDate">NOW</attribute> <attribute name="SchedulePeriod">60000</attribute> <attribute name="InitialRepetitions">1</attribute> <attribute name="TimerName">jboss:service=Timer,name=TranslationServiceTimer</attribute> <depends><mbean code="javax.management.timer.Timer" name="jboss:service=Timer,name=TranslationServiceTimer"/></depends> <depends>jboss.j2ee:service=EJB,jndiName=de/repower/lvs/i18n/sessionbeans/LVSTranslation</depends> </mbean> As the service is deployed in the same vm as the session bean I want to call the session bean via the local interface, but I get a SecurityException when I try to create an instance. When instead I do a lookup of the RemoteInterface it works. This is the code inside the perform method of my service class: public void perform(Date now, long remainingRepetitions) { try { final UsernamePasswordHandler handler = new UsernamePasswordHandler(USERNAME, PASSWORD); final LoginContext lc = new LoginContext("client-login", handler); lc.login(); // Trying to instantiate an LVSKeepAliveDispatcher via remote interface // This part works LVSKeepAliveDispatcher localvHome = LVSKeepAliveDispatcherUtil.getHome().create(); LOGGER.info("Successfully instantiated an LVSKeepAliveDispatcher " + localvHome.toString()); // Trying to instantiate an LVSKeepAliveDispatcherLocal via local interface LVSKeepAliveDispatcherLocal localvLocalHome = LVSKeepAliveDispatcherUtil.getLocalHome().create(); // this code is unforunately never reached LOGGER.info("Successfully instantiated an LVSKeepAliveDispatcherLocal " + localvLocalHome.toString()); lc.logout(); } catch (final Exception ex) { LOGGER.error("Error: ", ex); } } Exception: 2009-02-17 10:38:02,266 INFO [lvsi18n] (Timer-2) Successfully instantiated an LVSKeepAliveDispatcher de/repower/lvs/server/service/alive/sessionbeans/LVSKeepAliveDispatcher:Stateless 2009-02-17 10:38:02,297 ERROR [org.jboss.ejb.plugins.SecurityInterceptor] (Timer-2) Error in Security Interceptor java.lang.SecurityException: Authentication exception, principal=internalSystemUser at org.jboss.ejb.plugins.SecurityInterceptor.checkSecurityContext(SecurityInterceptor.java:321) at org.jboss.ejb.plugins.SecurityInterceptor.process(SecurityInterceptor.java:243) at org.jboss.ejb.plugins.SecurityInterceptor.invokeHome(SecurityInterceptor.java:205) at org.jboss.ejb.plugins.security.PreSecurityInterceptor.process(PreSecurityInterceptor.java:136) at org.jboss.ejb.plugins.security.PreSecurityInterceptor.invokeHome(PreSecurityInterceptor.java:88) at org.jboss.ejb.plugins.LogInterceptor.invokeHome(LogInterceptor.java:132) at org.jboss.ejb.plugins.ProxyFactoryFinderInterceptor.invokeHome(ProxyFactoryFinderInterceptor.java:107) at org.jboss.ejb.SessionContainer.internalInvokeHome(SessionContainer.java:639) at org.jboss.ejb.Container.invoke(Container.java:1046) at org.jboss.ejb.plugins.local.BaseLocalProxyFactory.invokeHome(BaseLocalProxyFactory.java:362) at org.jboss.ejb.plugins.local.LocalHomeProxy.invoke(LocalHomeProxy.java:133) at $Proxy193.create(Unknown Source) at de.repower.lvs.server.service.translation.TranslationService.perform(TranslationService.java:68) at org.jboss.varia.scheduler.Scheduler$PojoScheduler.invoke(Scheduler.java:1267) at org.jboss.varia.scheduler.Scheduler$BaseListener.handleNotification(Scheduler.java:1235) at sun.reflect.GeneratedMethodAccessor281.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.jboss.mx.notification.NotificationListenerProxy.invoke(NotificationListenerProxy.java:153) at $Proxy87.handleNotification(Unknown Source) at javax.management.NotificationBroadcasterSupport.handleNotification(NotificationBroadcasterSupport.java:257) at javax.management.NotificationBroadcasterSupport$SendNotifJob.run(NotificationBroadcasterSupport.java:322) at javax.management.NotificationBroadcasterSupport$1.execute(NotificationBroadcasterSupport.java:307) at javax.management.NotificationBroadcasterSupport.sendNotification(NotificationBroadcasterSupport.java:229) at javax.management.timer.Timer.sendNotification(Timer.java:1234) at javax.management.timer.Timer.notifyAlarmClock(Timer.java:1203) at javax.management.timer.TimerAlarmClock.run(Timer.java:1286) at java.util.TimerThread.mainLoop(Timer.java:512) at java.util.TimerThread.run(Timer.java:462) To further diagnose the error I debugged through the SecurityInterceptor and found that in the first case (successful creating an instance via the remote interface) the security context "lvs-security" (which I defined in login-config.xml) is being used whereas in the second case (failure when creating an instance via the local interface) the generic security context "CLIENT-LOGIN" is being used. This is the definition of the securit context "lvs-security" in login-config.xml: <application-policy name = "lvs-security"> <authentication> <login-module code = "org.jboss.security.ClientLoginModule" flag = "required"> </login-module> <login-module code = "de.repower.lvs.security.UsersRolesLoginModule" flag = "sufficient"> </login-module> <login-module code = "de.repower.lvs.security.login.LVSLoginModule" flag = "required"> <module-option name = "lvs-jboss-host">localhost</module-option> <module-option name = "lvs-jboss-jndi-port">1099</module-option> </login-module> </authentication> </application-policy> I'm now kind of stuck and hope someone can give me a hint about where to further look for the cause of the problem. This worked fine in JBoss 3.2.7. Edit: My current workaround for this problem: create a new container configuration in jboss.xml and remove the security interceptor stuff from this configuration use this newly created container configuration for all my session beans that I only use locally (i.e. via local interface).

  • VS.NET 2010 SP1, Win 7, Parallels, and a MBP&ndash;Hell, my friends&hellip;HELL!

    - by D'Arcy Lussier
    LightSwitch Beta 2 is out. That’s how all this started. All I wanted was to install it on my MBP’s Win7 Parallels VM. But as I’m finding with running a Win7 VM on a MBP, nothing is as easy as it should be. First my MBP froze during the SP1 installation. Not my VM crashing, the entire machine freezing…no mouse, nothing. Had to do a hard reset. BLECH. Then we’re back and I try to re-install SP1 (since the first try obviously failed). I get met with a dialog asking me where silverlight_sdk.msi was. It was *nowhere*! So I hit the net and download it from Microsoft’s site. Unfortunately, it only downloads an exe and not the individual files which would include the msi. Here’s what I did: - Download the tools for Silverlight 4 (http://www.microsoft.com/downloads/en/details.aspx?FamilyID=b3deb194-ca86-4fb6-a716-b67c2604a139&displaylang=en) - Run it, but don’t hit the install or next button when the dialog comes up - Look in your file structure for a folder with a weird name…bunch of numbers and letters. This is a temp folder that the exe creates and dumps all the necessary setup files into, and clears away after its done. - Inside this folder you’ll find the silverlight_sdk.msi (hooray!). Just copy it to a different location on the C drive. You can then cancel installation. Ok, so that takes care of that…but then running the SP1 installer I get hit with *another* dialog asking for the WCF RIA Services SP1 msi. Now it looks like this MSI is part of the Silverlight Tools package because you’ll see the MSI, but the VS.NET 2010 SP1 installer will thumb its nose at this unworthy msi…for whatever reason. So instead, go here: http://www.silverlight.net/getstarted/riaservices/ …and click on the “Install WCF Ria Services Sp1…” option. This downloads the msi, which you should save to your C drive and direct the VS.NET 2010 SP1 installer to. Then, if you’ve done all that, been good all year, and not made any little children cry, you *might* just be able to install VS.NET 2010 SP1 on your Parallels VM. If you were playing that “Take a shot every time he writes VS.NET 2010 Sp1” drinking game, then you’re drunk…which is a better place to be than where I am right now: watching the installation progress bar slowly creep to completion, hoping there’s no more surprises in store.

  • Problem using Hibernate-Search

    - by KCore
    Hi, I am using hibernate search for my application. It is well configured and running perfectly till some time back, when it stopped working suddenly. The reason according to me being the number of my model (bean) classes. I have some 90 classes, which I add to my configuration, while building my Hibernate Configuration. When, I disable hibernate search (remove the search annotations and use Configuration instead of AnnotationsConfiguration), I try to start my application, it Works fine. But,the same app when I enable search, it just hangs up. I tried debugging and found the exact place where it hangs. After adding all the class to my AnnotationsConfiguration object, when I say cfg.buildSessionfactory(), It never comes out of that statement. (I have waited for hours!!!) Also when I decrease the number of my model classes (like say to half i.e. 50) it comes out of that statement and the application works fine.. Can Someone tell why is this happening?? My versions of hibernate are: hibernate-core-3.3.1.GA.jar hibernate-annotations-3.4.0.GA.jar hibernate-commons-annotations-3.1.0.GA.jar hibernate-search-3.1.0.GA.jar Also if need to avoid using AnnotationsConfiguration, I read that I need to configure the search event listeners explicitly.. can anyone list all the neccessary listeners and their respective classes? (I tried the standard ones given in Hibernate Search books, but they give me ClassNotFound exception and I have all the neccesarty libs in classpath) Here are the last few lines of hibernate trace I managed to pull : 16:09:32,814 INFO AnnotationConfiguration:369 -

  • Prepping a conference

    - by Laurent Bugnion
    I have had the chance to talk at many conferences these past few years, and came up with a way to prepare them which works really well for me. Most importantly, it would make it quite easy to overcome an emergency (for example if my laptop would suddenly lose data). The whole code as well as the slides and other documents are in the cloud. I also use source control for my demos, so that I always have the latest and the greatest, but also a history of changes I made to my demos. Finally I have a system of code snippets which works great, and I often had very positive remarks from the audience regarding that. Putting everything in the cloud The one thing I used to be the most scared of was a sudden crash of my laptop, and being unable to restore in time for a conference. Most conferences ask speakers to send slides a few days (or weeks…) in advance, but let's face it, we all have last minute changes to our talks and I always come in the conference with updated slides that I pass to the management team. The answer to that dilemma used to be working off memory sticks, and that worked not bad. However last year I started putting all the documents relating to a conference in a DropBox folder, and that works great too. Obviously DropBox works only if you have connectivity, so if I for instance update slides while on an international flight, I cannot save to the cloud. The obvious answer to that is to backup everything on a memory stick… but I have to admit, I have been trusting my luck and working off my laptop HD and then synching everything to the cloud after landing. Of course on some US national flights you get WiFi on board, so in that case it is even simpler :) Usually after the conference is done, I remove the files from DropBox and copy them to their "final destination". They are backed up from there to BackBlaze, the great online backup service I am using routinely (I currently have about 90GB of data in BackBlaze). Outlining the presentations I like to have a written outline of my presentations written somewhere. I keep it simple, just write the various sections of the presentation with timing. I guess it is a remnant of the time when I was a private pilot, and using checklists for flight preparation. For example: Demo about designability 15' (0:37) Switch to Blend Open MainPage.xaml Create a DataTemplate ... Here I can immediately see during the presentation if I am taking too much time for my demo (0:37 is where I need to be when I am done with this section of the presentation, and 15' is the time that this particular section takes). I keep these sections reasonable, I don't detail every step of the preparation. Typically I have one such section for every 10-15 minutes of my talks. Yes, I am timing my presentations. I keep adjusting these numbers when I rehearse, and this really helps to feel more confident during the presentations. This is especially important for presentations that are long, like my MIX11 demo which clocked at 57 minutes (I had a lot of stuff to show…). Such presentations are risky, because if anything goes wrong, you will have to cut stuff, so the answer to that is: Rehearse, rehearse and when you're done rehearsing, rehearse a little more. I also have a "Preparation" section where I outline what I need to do before a presentation. For instance: Preparation Reboot in VHD Make sure MSN and Twitter are not running. Open VS10 and load demo Open Blend and load demo Run the WP7 emulator ... I typically start preparing my laptop an hour before the talk, starting everything I need to start and then putting my laptop to sleep. Saving and printing the outline, Timing Printing is a real problem because it is really hard to find a printer at most conference venues, and also quite hard in hotels. To solve that, I simply write everything in OneNote (synched to the cloud, now you start to know what I like ;) and then I print it to a PDF (I use CutePDFWriter) that I save to my Kindle. During the presentation, I read the outline off the Kindle (I mostly just need a quick check to see how I am timing). For timing during the presentation, I use the free tool ChronoGPS on my Windows Phone 7, but of course any phone these days has a clock/chrono application. In some conferences, they even have timers that the presenters can see, but they tend to count down and I prefer to count up… so I just use my own :) Source control for demos For demos, I create a separate folder and use Mercurial as source control. Mercurial has the huge advantage (over SVN or TFS) to work offline too, so I can commit while on a plane, and all the history is saved. Then when I have connectivity I push everything to the cloud (I am using the fantastic Trunksapp.com for my private repositories). Here too the obvious downside is the risk of losing my last changes if my laptop crashes before I can push to the cloud, and here too the obvious answer would be to work from a memory stick… though I have to admit I didn't do that lately (except when I was writing Silverlight 4 Unleashed, where I was really paranoid…) And code snippets? I am one of these presenters who hates to type in front of an audience. I can type really fast (writing two books has this advantage, it really teaches you to touch type and be fast at it) but in the context of an audience, on a stage where it is often damn cold (an issue I had a lot in past conferences, air conditioning can freeze your fingers and make it really hard to type), it doesn't work as well. I don't know for you, but I really dislike seeing a presentation where the speaker uses the backspace key more often than others ;) To solve that, I like to have my code ready in snippets, and drag them to the screen. Then I can spend time explaining each code snippet, while highlighting portions of the code (always highlight what you talk about, the audience often doesn't even see the cursor and doesn't know where you are on the screen!) Over the years I have used various solutions for code snippets, and now I have one which works really well… if you take a few precautions! I use the Visual Studio Toolbox. Preparing the code snippets You can store code snippets in the Toolbox for anything, XAML, C# etc. I arrange the snippets in the order in which I need them, which is a great way to remember what comes next in the presentation. I also separate them by topic, to make it easier to find them, for example when I switch to the slides and then back to the code. Remember that no matter how experienced you are, you will feel more nervous on stage than while you are preparing, so any way to make it easier for you is going to be beneficial to the audience. To store a code snippet, I do the following: Open the final demo that you want to show to the audience in Visual Studio. In your code, select a snippet of code that you want to explain in particular. Make sure that the Visual Studio Toolbox is open (menu View, Toolbox or Ctrl-Alt-X). Drag the selected snippet from the code window to the toolbox. (if needed) drag the snippet to the correct location (for example between two other code snippets so that you can access it as you speak through the demo). Right click on the snippet and select Rename Item from the context menu. Select a meaningful name. For me I use the following conventions: If it is a method, I use the method's name. If it is not a whole method, I use a descriptive name. If it is the content of a method (i.e. the body only, without the method's signature), I use "-> MethodName". This reminds me during the presentation that this is only the body, and that I need to insert that into an existing signature. This is the case, for instance, when I use Visual Studio to automatically generate the members of an interface’s implementation; then I only need to insert my snippet inside the generated method body. Saving the snippets This is the most important!! It happened to me a few times that VS10 lost its settings. When that happens, the snippets are lost too! Yeah that really sucks, especially (as it happened once) when this is the case about an hour before a talk… Stress and sweat follows, not good conditions to start a talk in front of an audience believe me. Thankfully, saving snippets is really easy with the following steps: Select the menu Tools, Import and Export Settings. Select Export selected environment settings and press Next. Uncheck All Settings. Then expand General Settings and select Toolbox (only!). Press Next. Select your source control folder and save under a meaningful name (for instance Snippets.vssettings). Commit to source control and push to the cloud. By the way, this also has the advantage of applying source control to the snippets file (which is an XML file), so you get history for free on that file! Reimporting the snippets If VS loses its settings and you need to reimport the snippets, this can be done super easily and very fast. Make sure that the Toolbox is empty. When you import snippets, they are merged with existing ones, they do not replace the content of the Toolbox. Unless merging is really what you want, make sure that your Toolbox is clean before you import, it is really easier. Select the menu Tools, Import and Export Settings. Select Import selected environment settings and press Next. Select No, just import new settings and press Next. Press Browse and select the Snippets.vssettings file. Press Finish. Et voila, all your snippets appear again in the Toolbox. Whew, the worst was averted and you can start your demo without sweating! (I had to do that once literally 5 minutes before the start of a demo, while my laptop was already hooked to the projector, and it went just fine). What about special tools? When using special tools (for example beta versions of tools you have an early access to), or a special configuration of your laptop, things can get tricky because you cannot really be sure that you will get a laptop with the same tools and the same configuration at the conference. To solve that, I use the following precautions: I make my demos from a Virtual Hard Disk. The great John Papa made a very easy-to-follow web page where he explains how to create a VHD and install Win7 to it. This gives you the full power of your laptop (as fast as booting from the metal). For me, I have a basic configuration that I saved on a USB harddrive (Win7 plus drivers, basic settings for desktop, folder options, taskbar etc) and Visual Studio 2010 SP1 on it. When preparing, I start by copying this "basis VHD" to my laptop. I install additional tools and configurations. I save the VHD back to the USB harddrive in a different folder. This would allow me to reinstall my demo environment quite fast, for example in case of harddrive failure. Replace the harddrive, copy the VHD to it, configure the BCD and you can start. Unfortunately this only works if the laptop itself still works. In the worst case of total failure, my security is to back all the installers up: The installers I use are synched on all my laptops and backed up to BackBlaze. If the worst happens and my laptop is absolutely broken, I can download the installer from BackBlaze and install on another laptop. This of course takes some time, and if that happens 5 minutes before a presentation, well… I don't have an answer to that, except of course crossing my fingers. Still, all that gives me additional security. Conclusion Remember folks, talking to an audience, large or small, will make you nervous. Just ask Scott Hanselman :) The goal here is to create the best possible conditions for you, and to create an environment where everything is saved and easy to restore, where everything is well known and provides you with additional confidence. The cooler you feel before the presentation (and during ;)), the better your presentation will be. Here too, the goal is to provide the best user experience you can have, which in turn will make it more enjoyable for your audience! Happy presenting :) Laurent   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

  • Django as Python extension?

    - by NoobDev4iPhone
    I come from php community and just started learning Python. I have to create server-side scripts that manipulate databases, files, and send emails. Some of it I found hard to do in python, comparing to php, like sending emails and querying databases. Where in php you have functions like mysql_query(), or email(), in python you have to write whole bunch of code. Recently I found Django, and my question is: is it a good framework for network-oriented scripts, instead of using it as a web-framework?

  • SOLVED Install MythTV & 11.10 on Lenovo S12 (Intel atom) with wireless

    - by keepitsimpleengineer
    This is how I installed Ubuntu 11.10 and MythTV client on my Lenovo S12 (Intel Atom) laptop and use it using WiFi (see additional notes at end). I did this because the upgrade from 11.04 bricked the laptop. Note that the partitions on the Lenovo standard disk were already in place for this installation. Also note that my LAN is setup for fixed IP addresses. Downloaded and burned 11.10 x86 Desktop Ubuntu CD Connected the power supply cord, LAN wire and the external DVD USB drive. Ran Windows XP and made sure performance level "Performance" was set and "Wireless" was enabled. Booted S12 from CD Disabled Networking from icon on upper left panel icon Edited Connections… "Wired connection 1" ? Set IP address, accepted default netmask and set gateway. Also set DNS server. Good idea to check "Connection Information" here to verify everything's O.K. Selected Install Ubuntu from the initial "Install" window Verified the three items were checked (required disk space available, plugged into a power source, & connected to the Internet) Selected Download updates while installing and third party software. Hit Continue… At wireless selected don't want to connect…WiFi…now. Continue… At Installation type, selected Something else. Continue… At partition tale, selected the ext4 Linux partition, set the mount point as "/", and marked for formatting. Here I selected the main disk (/sda) for installing the boot manager. Continue… Selected or verified my Time zone. Continue… Selected my keyboard layout. Continue… Filled in the who are you fields. Make sure password is required to sign in is checked. Continue… Chose a picture. Continue… I selected import no accounts. Continue… Wait as the Install creeps along. If your screen goes blank, tap the space bar ? apparently the screen saver/power plan does this. There are several progress bars. The longest was "Installing system", and it was the next to the last one. Installation Complete window appears, Restart Now… Wait as it stops, The screen blanks then the message "…remove…media…close tray…press enter" I just unplugged the USB DVD and hit enter… It was disheartening but the screen turned Ubuntu Purple-beige and nothing happened, so I help down the power key until it shut down, the pressed it again and the Grub Boot screen appeared. Select Ubuntu… 25.The screen went blank with the little flashing underscore cursor on it and the disk light would occasionally flash. I hit the enter key and eventuality Ubuntu started. After a somewhat long time the unity desktop appeared. 11.10, unlike earlier versions, retains the connection information. Check this by checking the network icon on the upper left applet panel. Here the touch-pad·mouse quit working and I had to reboot. It takes and extremely long time to boot, sometimes requiring several power off/ power on (cold boot). You can try to get the default network manager to work, but it might not, it didn't on mine for WiFi. Thanks to: Chris at URL here's what to do… disconnect your wired Internet connection. input your wireless information into network manager open a terminal (unity dash, top of icon totem, open, and make sure the ruler&pen icon on the bottom is selected, 2nd from left) type in "terminal". Might be a good idea to drag and drop the terminal icon to the terminal, it's easy to get rid of later. click to open a terminal, and type in: sudo rmmod acer_wmi && echo "blacklist acer_wmi" >> /etc/modprobe.d/blacklist.conf and hit enter. type in your password as asked. if you have correctly entered your WiFi information and you are near your AP, you should connect immediately if not, see the URL above ? you might need to replace "network manager" with "wicd" ? I did with 11.04. Update the new 11.10, in the upper left panel applet weird·gear icon is menu with a line about updating. It's the new way to invoke Update Manager. Your lenovo S12 (intel atom) should now run the new unity Ubuntu. Point your elbow at the ceiling and pat yourself on the back.

Type in mythbuntu-control-centre in the Quick filter text box, and then select it "Mark for installation" by clicking on the box next to it's name. Marvel at the additional to be installed items, then select "?Mark"… At the top of the synaptic window click on the "? Apply" button. Marvel at the amount of stuff to be installed, the click on "Apply". When finished, close finished window and synaptic.

From Setup TV Settings Playback Alt-N(ext) Alt-N(ext) Playback Profiles (3/8) : Change Current Video Playback Profile to "Normal". You can fiddle with this setting later. For the lenovo S12, the second thing is to get the sound going.

Then Tab down to Audio Output Device: and left-right arrow until "ALSA:hw:Card=Intel,DEV=0" is selected. Then Alt-N(ext) until "Finish". Now you should have sound. You should now have MythTV working nicely on the Lenovo S12 Notes about wireless: Running Lenovo S12 on wireless is demanding on both power and WiFi connection.

Here Mythbuntu client-server (in den) <? wireless link 1 <?office LAN? wireless link 2 <? Lenovo S12 Ubuntu 11.10 The office LAN is fixed IP behind an Untangle firewall router.

In addition, the client mythtv when used all other users of its access point are turned off except for a Skype phone. Also, the client-server is set up to allow other connections though it's LAN connection, and these are used to connect the TV and disc players, not used when client is being used.

  • Playing NSF music in FMOD.net

    - by Tesserex
    So, as the title says, I want to be able to play NSF files using FMOD, because my project already uses FMOD and I'd rather not replace it. This will involve figuring out how existing players and emulators work and porting it. I haven't yet found an existing player that uses FMOD. My starting point is the MyNes source from http://sourceforge.net/projects/mynes/. There are two big steps between here and what I'm looking for. MyNes plays from a ROM, not NSF. So, I have to rip out the APU and get it to play NSF files. The MyNes APU uses SlimDX, so I have to convert that to FMOD.NET. I am really stuck about how to go about either of these, because I'm not that familiar with audio formats and it's hard finding resources online. So here are a few questions: From what I can tell from the NSF spec at http://kevtris.org/nes/nsfspec.txt, it's just contains the relevant memory section of the ROM, plus the header. If anyone can verify or correct this that would be great. The emulator APU uses data from the rest of the emulator to play, including things like cycle counts. I'm not sure what replaces this in a standalone player. Can't I just load all the music data at once into a stream and play it? Joining #1 and #2, does the header data from the NSF substitute for some of the ROM data in the emulator code? Using FMOD, will I be following the usercreatedsound example for loading a stream? And does this format count as PCM? Specifically MyNes says PCM8. Any tips on loading / playing the stream in FMOD are appreciated. As an aside, I don't really understand the loading / playing sections of the spec I linked at all. It seems to apply to 6502 systems / emulators only and not to my situation. I know it's a long shot for anyone here to have enough experience in this area to help, but anything you can provide is definitely appreciated. A link to an existing .NET library that does this would be even better, but I don't believe one exists.

Many dynamic programming environments back in the old days used to be self-contained VM images, e.g. SmallTalk, GemStone/S. One could checkpoint, modify, and ship these images wholesale and have it up and running with very little effort. Fast forward to now and I'm still using Make files to configure and install binaries.

    I do a lot of local web development work on my Ubuntu machine, and I'm constantly setting up virtual hosts in Apache. I don't need to do hard core server management, but I am getting tired of the repetitive process of manually adding config directives to files in /etc/apache2/sites-available/ and then updating the /etc/hosts file. Is there a more efficient or more automated way to do all this that I'm missing? Maybe something like rapache but that's actually working?

  • Installing Forms and Reports on a development system

    - by Duncan Mills
    By popular demand I've resurrected / updated one of the old blog postings from Jan Carlin's Blog on GroundSide here. A recent (lengthy) post on the Forms forums chronicles the problems some of you have had installing F&R on a development machine. See the link in the headline of this post for the main one. When installing, here are some points to bear in mind: Download and install Weblogic Server first. http://www.oracle.com/technology/software/products/middleware/index.htmlFind the Forms and Reports (and Disco and Portal) zip files here. Download them to the desktop (or some other temporary directory of your choosing). Unzip both of the two zip files into the same new directory (maybe called 'stage') and check that you have 4 directories in the stage dir when you are finished unzipping: 'Disk1', 'Disk2', 'Disk3' and 'Disk4'. These folders are specified in the zip file structure and must be preserved for the setup executable to work. If you use WinZip and have a right click menu option that say "Extract to here", use that by right click-dragging the zip file onto the newly created directory. Don't use the "Extract to folder %HOME%\Desktop\ofm_pfrd...disk_1of2" option. That will get you into the trouble that was reported early in this thread. Free up as much memory as you can. Stop services and background processes and virus scanners and databases (you don't need a DB to install Forms) and other things lurking about on your machine. You can restart them when the install is done. Around 1.5 GB free real memory should do it. If it doesn't, free up more if you can. Don't change the swap space unless you know what you are doing. Let Windows handle it. A 1 GB machine will likely not be enough. You will likely need at least 2GB of RAM.Start the install with setup.exe from the 'Disk1' directoryChoose the Install and Configure option unless you have a good reason not to.Choose a unique instance name even if you deinstalled and removed the last install. I suggest using 'asinst_20090722_1' (today's date in ISO format with a running incremented number at the end if you install more than two times on a particular day).Unselect Portal and Discoverer and select the Builders you want.Unselect WebCacheUnselect OHS.Unselect the single sign-on option Check for any failures and choose the retry option if any occur. If that doesn't fix the problem, call Oracle Customer Support .

Should I just delete the files manually? And then, should I resize my /boot to be larger, so this doesn't happen again? If so, how? If not, what maintenance should I be running regularly to prevent the accumulation of this cruft?
