• 64-bit 13.10 shows 1GB less RAM than 64-bit 13.04 did

  - by kiloseven

  Multiple 64-bit versions (Kubuntu, Lubuntu and Xubuntu) once installed on my ThinkPad R60 show 3GB of RAM, not the correct 4GB of RAM. Last week with 13.04, I had 4GB of RAM (which matches the BIOS) and this week I have 3GB available. Inquiring minds want to know. Details follow: Linux R60 3.11.0-12-generic #19-Ubuntu SMP Wed Oct 9 16:20:46 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux r60 free -m reports: _ total used free shared buffers cached Mem: 3001 854 2146 0 22 486 -/+ buffers/cache: 346 2655 Swap: 0 0 0 . . . . . . lshw shows: description: Notebook product: 9459AT8 () vendor: LENOVO version: ThinkPad R60/R60i serial: redacted width: 64 bits capabilities: smbios-2.4 dmi-2.4 vsyscall32 configuration: administrator_password=disabled boot=normal chassis=notebook family=ThinkPad R60/R60i frontpanel_password=unknown keyboard_password=disabled power-on_password=disabled uuid=126E4001-48CA-11CB-9D53-B982AE0D1ABB *-core description: Motherboard product: 9459AT8 vendor: LENOVO physical id: 0 version: Not Available *-firmware description: BIOS vendor: LENOVO physical id: 0 version: 7CETC1WW (2.11 ) date: 01/09/2007 size: 144KiB capacity: 1984KiB capabilities: pci pcmcia pnp upgrade shadowing escd cdboot bootselect socketedrom edd acpi usb biosbootspecification {snip} *-memory description: System Memory physical id: 29 slot: System board or motherboard size: 4GiB *-bank:0 description: SODIMM DDR2 Synchronous physical id: 0 slot: DIMM 1 size: 2GiB width: 64 bits *-bank:1 description: SODIMM DDR2 Synchronous physical id: 1 slot: DIMM 2 size: 2GiB width: 64 bits dpkg -l linux-* returns: Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Description +++-======================================-=======================================-========================================================================== un linux-doc-3.2.0 (no description available) ii linux-firmware 1.79.6 Firmware for Linux kernel drivers ii linux-generic 3.2.0.52.62 Complete Generic Linux kernel un linux-headers (no description available) un linux-headers-3 (no description available) un linux-headers-3.0 (no description available) un linux-headers-3.2.0-23 (no description available) un linux-headers-3.2.0-23-generic (no description available) ii linux-headers-3.2.0-52 3.2.0-52.78 Header files related to Linux kernel version 3.2.0 ii linux-headers-3.2.0-52-generic 3.2.0-52.78 Linux kernel headers for version 3.2.0 on 64 bit x86 SMP ii linux-headers-generic 3.2.0.52.62 Generic Linux kernel headers un linux-image (no description available) un linux-image-3.0 (no description available) ii linux-image-3.2.0-52-generic 3.2.0-52.78 Linux kernel image for version 3.2.0 on 64 bit x86 SMP ii linux-image-generic 3.2.0.52.62 Generic Linux kernel image un linux-initramfs-tool (no description available) un linux-kernel-headers (no description available) un linux-kernel-log-daemon (no description available) ii linux-libc-dev 3.2.0-52.78 Linux Kernel Headers for development un linux-restricted-common (no description available) ii linux-sound-base 1.0.25+dfsg-0ubuntu1.1 base package for ALSA and OSS sound systems un linux-source-3.2.0 (no description available) un linux-tools (no description available)

• Integrating Flickr with ASP.Net application

  - by sreejukg

  Flickr is the popular photo management and sharing application offered by yahoo. The services from flicker allow you to store and share photos and videos online. Flicker offers strong API support for almost all services they provide. Using this API, developers can integrate photos to their public website. Since 2005, developers have collaborated on top of Flickr's APIs to build fun, creative, and gorgeous experiences around photos that extend beyond Flickr. In this article I am going to demonstrate how easily you can bring the photos stored on flicker to your website. Let me explain the scenario this article is trying to address. I have a flicker account where I upload photos and share in many ways offered by Flickr. Now I have a public website, instead of re-upload the photos again to public website, I want to show this from Flickr. Also I need complete control over what photo to display. So I went and referred the Flickr documentation and there is API support ready to address my scenario (and more… ). FlickerAPI for ASP.Net To Integrate Flicker with ASP.Net applications, there is a library available in CodePlex. You can find it here http://flickrnet.codeplex.com/ Visit the URL and download the latest version. The download includes a Zip file, when you unzip you will get a number of dlls. Since I am going to use ASP.Net application, I need FlickrNet.dll. See the screenshot of all the dlls, and there is a help file available in the download (.chm) for your reference. Once you have the dll, you need to use Flickr API from your website. I assume you have a flicker account and you are familiar with Flicker services. Arrange your photos using Sets in Flickr In flicker, you can define sets and add your uploaded photos to sets. You can compare set to photo album. A set is a logical collection of photos, which is an excellent option for you to categorize your photos. Typically you will have a number of sets each set having few photos. You can write application that brings photos from sets to your website. For the purpose of this article I already created a set Flickr and added some photos to it. Once you logged in to Flickr, you can see the Sets under the Menu. In the Sets page, you will see all the sets you have created. As you notice, you can see certain sample images I have uploaded just to test the functionality. Though I wish I couldn’t create good photos so please bear with me. I have created 2 photo sets named Blue Album and Red Album. Click on the image for the set, will take you to the corresponding set page. In the set “Red Album” there are 4 photos and the set has a unique ID (highlighted in the URL). You can simply retrieve the photos with the set id from your application. In this article I am going to retrieve the images from Red album in my ASP.Net page. For that First I need to setup FlickrAPI for my usage. Configure Flickr API Key As I mentioned, we are going to use Flickr API to retrieve the photos stored in Flickr. In order to get access to Flickr API, you need an API key. To create an API key, navigate to the URL http://www.flickr.com/services/apps/create/ Click on Request an API key link, now you need to tell Flickr whether your application in commercial or non-commercial. I have selected a non-commercial key. Now you need to enter certain information about your application. Once you enter the details, Click on the submit button. Now Flickr will create the API key for your application. Generating non-commercial API key is very easy, in couple of steps the key will be generated and you can use the key in your application immediately. ASP.Net application for retrieving photos Now we need write an ASP.Net application that display pictures from Flickr. Create an empty web application (I named this as FlickerIntegration) and add a reference to FlickerNet.dll. Add a web form page to the application where you will retrieve and display photos(I have named this as Gallery.aspx). After doing all these, the solution explorer will look similar to following. I have used the below code in the Gallery.aspx page. The output for the above code is as follows. I am going to explain the code line by line here. First it is adding a reference to the FlickrNet namespace. using FlickrNet; Then create a Flickr object by using your API key. Flickr f = new Flickr("<yourAPIKey>"); Now when you retrieve photos, you can decide what all fields you need to retrieve from Flickr. Every photo in Flickr contains lots of information. Retrieving all will affect the performance. For the demonstration purpose, I have retrieved all the available fields as follows. PhotoSearchExtras.All But if you want to specify the fields you can use logical OR operator(|). For e.g. the following statement will retrieve owner name and date taken. PhotoSearchExtras extraInfo = PhotoSearchExtras.OwnerName | PhotoSearchExtras.DateTaken; Then retrieve all the photos from a photo set using PhotoSetsGetPhotos method. I have passed the PhotoSearchExtras object created earlier. PhotosetPhotoCollection photos = f.PhotosetsGetPhotos("72157629872940852", extraInfo); The PhotoSetsGetPhotos method will return a collection of Photo objects. You can just navigate through the collection using a foreach statement. foreach (Photo p in photos) {     //access each photo properties } Photo class have lot of properties that map with the properties from Flickr. The chm documentation comes along with the CodePlex download is a great asset for you to understand the fields. In the above code I just used the following p.LargeUrl – retrieves the large image url for the photo. p.ThumbnailUrl – retrieves the thumbnail url for the photo p.Title – retrieves the Title of the photo p.DateUploaded – retrieves the date of upload Visual Studio intellisense will give you all properties, so it is easy, you can just try with Visual Studio intellisense to find the right properties you are looking for. Most of hem are self-explanatory. So you can try retrieving the required properties. In the above code, I just pushed the photos to the page. In real time you can use the retrieved photos along with JQuery libraries to create animated photo galleries, slideshows etc. Configuration and Troubleshooting If you get access denied error while executing the code, you need to disable the caching in Flickr API. FlickrNet cache the photos to your local disk when retrieved. You can specify a cache folder where the application need write permission. You can specify the Cache folder in the code as follows. Flickr.CacheLocation = Server.MapPath("./FlickerCache/"); If the application doesn’t have have write permission to the cache folder, the application will throw access denied error. If you cannot give write permission to the cache folder, then you must disable the caching. You can do this from code as follows. Flickr.CacheDisabled = true; Disabling cache will have an impact on the performance. Take care! Also you can define the Flickr settings in web.config file.You can find the documentation here. http://flickrnet.codeplex.com/wikipage?title=ExampleConfigFile&ProjectName=flickrnet Flickr is a great place for storing and sharing photos. The API access allows developers to do seamless integration with the photos uploaded on Flickr.

  I'm having frequent disconnects with my new install of Ubuntu 12.10. I tried updating the kernel driver to the latest intel release to no avail. My expertise is spent.

• Configure 27" 2560x1440 for a monitor with corrupt EDID

  - by Aras

  I am trying to get a monitor work with my Ubuntu laptop. The monitor is this cheap 27" Korean monitors which has a 2560x1440 resolution -- and nothing else. Here are some specifications of this monitor: 2560x1440 @60Hz Only one dual link DVI-D input -- no other input port (no HDMI or display port) no OSD no scalar reports corrupt EDID does 2560x1440 @60Hz, did I say that already? Anyways, the monitor works beautifully with my Ubuntu desktop which has an nVidia card with DVI output. However, I am having problem using this monitor with my laptop. After some searching around I found a few posts suggesting to use an active adaptor for mini display port, so I went and bought a mini display to dual link DVI-D adaptor.. When using this adaptor the monitor is recognized by nvidia-settings tool but with incorrect resolution information. As you can see the monitor is incorrectly recognized and there are no other resolution available to set. This post on ubuntu forums and this other post on overclock both suggest that the monitor is reporting corrupt EDID file. I have tried following their instructions, but so far I have not been able to display any image on the monitor from my laptop. The laptop I am using is an ASUS G75VW with a 1920x1080 screen. It has a VGA, an HDMI 1.4a, and a mini display port. The graphic card is an nvidia gforce gtx 660M with 2GB dedicated memory. I am running Ubuntu 12.10 on here which I upgrade from 12.04 a few weeks ago. As I said I have tried several suggestions, including specifying Modeline in xorg.conf and also linking to EDID files I found from those forum posts above. However, I am not sure if the EDID files I found are suitable for my monitor. I think the solution to my problem consist of obtaining the EDID file of my monitor and then fixing it and modifying xorg.conf to force nvidia driver to load the correct resolution. However, I am not sure what steps I need to take to do this. Here is the part of sudo xrandr --prop output that is related to this monitor: DP-1 connected 800x600+1920+0 (normal left inverted right x axis y axis) 0mm x 0mm SignalFormat: DisplayPort supported: DisplayPort ConnectorType: DisplayPort ConnectorNumber: 3 (0x00000003) _ConnectorLocation: 3 (0x00000003) 800x600 60.3*+ I was expecting to see the EDID file in this output as was mentioned in this post, but it is not there. After several hours of tweaking X configurations, I decided it was time to ask for help here. I would really appreciate if someone with experience regarding EDID and X configuration could give me a hand to solve this issue.

• What's the recommended way to configure a Synaptics touchpad device?

  - by htorque

  I want to increase the scroll area by moving the so-called RightEdge a bit towards the middle. Right now I'm doing this via a one-liner that's called at session start (added via gnome-session-properties): xinput --set-prop --type=int --format=32 11 252 1781 5125 1646 4582 This works fine, but feels like a hack. What's the recommended way to edit/set touchpad device properties like this one? Few years ago I'd have put that into the xorg.conf, but this seems to be discouraged nowadays.

• Deploying Socket.IO App to Windows Azure Web Site with Azure CLI

  - by shiju

  In this blog post, I will demonstrate how to deploy Socket.IO app to Windows Azure Website using Windows Azure Cross-Platform Command-Line Interface, which leverages the Windows Azure Website’s new support for Web Sockets. Recently Windows Azure has announced lot of enhancements including the support for Web Sockets in Windows Azure Websites, which lets the Node.js developers deploy Socket.IO apps to Windows Azure Websites. In this blog post, I am using  Windows Azure CLI for create and deploy Windows Azure Website. Install  Windows Azure CLI The Windows Azure CLI available as a NPM module so that you can install Windows Azure CLI using  NPM as shown in the below command. After installing the azure-cli, just enter the command “azure” which will show the useful commands provided by Azure CLI. Import Windows Azure Subscription Account In order to import our Azure subscription account, we need to download the Windows Azure subscription profile. The Azure CLI command “account download” lets you download the  Windows Azure subscription profile as shown in the below command. The command redirect you login to Windows Azure portal and allow you to download the Windows Azure publish settings file. The account import command lets you import the downloaded publish settings file so that you can create and manage Websites, Cloud Services, Virtual Machines and Mobile Services in Windows Azure. Create Windows Azure Website and Enable Web Sockets In this post, we are going to deploy Socket.IO app to Windows Azure Website by using the Web Socket support provided by Windows Azure. Let’s create a Website named “socketiochatapp” using the Azure CLI. The above command will create a Windows Azure Website that will also initialize a Git repository with a remote named Azure. We can see the newly created Website from Azure portal. By default, the Web Sockets will be disabled. So let’s enable it by navigating to the Configure tab of the Website, and select “ON” in Web Sockets option and save the configuration changes. Deploy a Node.js Socket.IO App to Windows Azure Now, our Windows Azure Website supports Web Sockets so that we can easily deploy Socket.IO app to Windows Azure Website. Let’s add Node.js chat app which leverages Socket.IO module. Please note that you have to add npm module dependencies in the package.json file so that Windows Azure can install the dependencies when deploying the app. Let’s add the Node.js app and add the files to git repository. Let’s commit the changes to git repository. We have committed the changes to git local repository. Let’s push the changes to Windows Azure production environment. The successful deployment can see from the Windows Azure portal by navigating to the deployments tab of the selected Windows Azure Website. The screen shot below shows that our chat app is running successfully.   You can follow me on Twitter @shijucv

• How to setup Dual Head with "radeon" driver for R770?

  - by user1709408

• Ubuntu doesn't let me to blacklist modules

  - by László Monda

  I'd like to blacklist a couple of modules, namely drm, drm_kms_helper, i2c_algo_bit and i915 to not allow my integrated Intel GPU to ever be used, but instead my Nvidia MXM card. I inserted the following lines into /etc/modprobe.d/blacklist.conf: blacklist i915 blacklist drm blacklist drm_kms_helper blacklist i2c_algo_bit Despite the above right after rebooting my laptop and typing lsmod I can see these modules loaded. Why does my blacklist get utterly disrespected and what can I do about it?

• Apply LADSPA filter to only one channel of multichannel output with Alsa and PulseAudio

  - by justinzane

  I want to apply a filter, specifically SWH's glame-bandpass-iir, to only one of several output channels. I want unfiltered output to go to the front, rear and LFE channels with bandpass filtered output for the center channel. I'm assuming that this needs to be done with Alsa's /etc/asound.conf but I cannot understand the documentation well enough to figure out how. If there is a better way, via PulseAudio, Jack or whatever, I'm open to whatever works. Thanks.

• Parent Objects

  - by Ali Bahrami

  Support for Parent Objects was added in Solaris 11 Update 1. The following material is adapted from the PSARC arc case, and the Solaris Linker and Libraries Manual. A "plugin" is a shared object, usually loaded via dlopen(), that is used by a program in order to allow the end user to add functionality to the program. Examples of plugins include those used by web browsers (flash, acrobat, etc), as well as mdb and elfedit modules. The object that loads the plugin at runtime is called the "parent object". Unlike most object dependencies, the parent is not identified by name, but by its status as the object doing the load. Historically, building a good plugin is has been more complicated than it should be: A parent and its plugin usually share a 2-way dependency: The plugin provides one or more routines for the parent to call, and the parent supplies support routines for use by the plugin for things like memory allocation and error reporting. It is a best practice to build all objects, including plugins, with the -z defs option, in order to ensure that the object specifies all of its dependencies, and is self contained. However: The parent is usually an executable, which cannot be linked to via the usual library mechanisms provided by the link editor. Even if the parent is a shared object, which could be a normal library dependency to the plugin, it may be desirable to build plugins that can be used by more than one parent, in which case embedding a dependency NEEDED entry for one of the parents is undesirable. The usual way to build a high quality plugin with -z defs uses a special mapfile provided by the parent. This mapfile defines the parent routines, specifying the PARENT attribute (see example below). This works, but is inconvenient, and error prone. The symbol table in the parent already describes what it makes available to plugins — ideally the plugin would obtain that information directly rather than from a separate mapfile. The new -z parent option to ld allows a plugin to link to the parent and access the parent symbol table. This differs from a typical dependency: No NEEDED record is created. The relationship is recorded as a logical connection to the parent, rather than as an explicit object name However, it operates in the same manner as any other dependency in terms of making symbols available to the plugin. When the -z parent option is used, the link-editor records the basename of the parent object in the dynamic section, using the new tag DT_SUNW_PARENT. This is an informational tag, which is not used by the runtime linker to locate the parent, but which is available for diagnostic purposes. The ld(1) manpage documentation for the -z parent option is: -z parent=object Specifies a "parent object", which can be an executable or shared object, against which to link the output object. This option is typically used when creating "plugin" shared objects intended to be loaded by an executable at runtime via the dlopen() function. The symbol table from the parent object is used to satisfy references from the plugin object. The use of the -z parent option makes symbols from the object calling dlopen() available to the plugin. Example For this example, we use a main program, and a plugin. The parent provides a function named parent_callback() for the plugin to call. The plugin provides a function named plugin_func() to the parent: % cat main.c #include <stdio.h> #include <dlfcn.h> #include <link.h> void parent_callback(void) { printf("plugin_func() has called parent_callback()\n"); } int main(int argc, char **argv) { typedef void plugin_func_t(void); void *hdl; plugin_func_t *plugin_func; if (argc != 2) { fprintf(stderr, "usage: main plugin\n"); return (1); } if ((hdl = dlopen(argv[1], RTLD_LAZY)) == NULL) { fprintf(stderr, "unable to load plugin: %s\n", dlerror()); return (1); } plugin_func = (plugin_func_t *) dlsym(hdl, "plugin_func"); if (plugin_func == NULL) { fprintf(stderr, "unable to find plugin_func: %s\n", dlerror()); return (1); } (*plugin_func)(); return (0); } % cat plugin.c #include <stdio.h> extern void parent_callback(void); void plugin_func(void) { printf("parent has called plugin_func() from plugin.so\n"); parent_callback(); } Building this in the traditional manner, without -zdefs: % cc -o main main.c % cc -G -o plugin.so plugin.c % ./main ./plugin.so parent has called plugin_func() from plugin.so plugin_func() has called parent_callback() As noted above, when building any shared object, the -z defs option is recommended, in order to ensure that the object is self contained and specifies all of its dependencies. However, the use of -z defs prevents the plugin object from linking due to the unsatisfied symbol from the parent object: % cc -zdefs -G -o plugin.so plugin.c Undefined first referenced symbol in file parent_callback plugin.o ld: fatal: symbol referencing errors. No output written to plugin.so A mapfile can be used to specify to ld that the parent_callback symbol is supplied by the parent object. % cat plugin.mapfile $mapfile_version 2 SYMBOL_SCOPE { global: parent_callback { FLAGS = PARENT }; }; % cc -zdefs -Mplugin.mapfile -G -o plugin.so plugin.c However, the -z parent option to ld is the most direct solution to this problem, allowing the plugin to actually link against the parent object, and obtain the available symbols from it. An added benefit of using -z parent instead of a mapfile, is that the name of the parent object is recorded in the dynamic section of the plugin, and can be displayed by the file utility: % cc -zdefs -zparent=main -G -o plugin.so plugin.c % elfdump -d plugin.so | grep PARENT [0] SUNW_PARENT 0xcc main % file plugin.so plugin.so: ELF 32-bit LSB dynamic lib 80386 Version 1, parent main, dynamically linked, not stripped % ./main ./plugin.so parent has called plugin_func() from plugin.so plugin_func() has called parent_callback() We can also observe this in elfedit plugins on Solaris systems running Solaris 11 Update 1 or newer: % file /usr/lib/elfedit/dyn.so /usr/lib/elfedit/dyn.so: ELF 32-bit LSB dynamic lib 80386 Version 1, parent elfedit, dynamically linked, not stripped, no debugging information available Related Other Work The GNU ld has an option named --just-symbols that can be used in a similar manner: --just-symbols=filename Read symbol names and their addresses from filename, but do not relocate it or include it in the output. This allows your output file to refer symbolically to absolute locations of memory defined in other programs. You may use this option more than once. -z parent is a higher level operation aimed specifically at simplifying the construction of high quality plugins. Although it employs the same operation, it differs from --just symbols in 2 significant ways: There can only be one parent. The parent is recorded in the created object, and can be displayed by 'file', or other similar tools.

• Integrating Coherence & Java EE 6 Applications using ActiveCache

  - by Ricardo Ferreira

  OK, so you are a developer and are starting a new Java EE 6 application using the most wonderful features of the Java EE platform like Enterprise JavaBeans, JavaServer Faces, CDI, JPA e another cool stuff technologies. And your architecture need to hold piece of data into distributed caches to improve application's performance, scalability and reliability? If this is your current facing scenario, maybe you should look closely in the solutions provided by Oracle WebLogic Server. Oracle had integrated WebLogic Server and its champion data caching technology called Oracle Coherence. This seamless integration between this two products provides a comprehensive environment to develop applications without the complexity of extra Java code to manage cache as a dependency, since Oracle provides an DI ("Dependency Injection") mechanism for Coherence, the same DI mechanism available in standard Java EE applications. This feature is called ActiveCache. In this article, I will show you how to configure ActiveCache in WebLogic and at your Java EE application. Configuring WebLogic to manage Coherence Before you start changing your application to use Coherence, you need to configure your Coherence distributed cache. The good news is, you can manage all this stuff without writing a single line of code of XML or even Java. This configuration can be done entirely in the WebLogic administration console. The first thing to do is the setup of a Coherence cluster. A Coherence cluster is a set of Coherence JVMs configured to form one single view of the cache. This means that you can insert or remove members of the cluster without the client application (the application that generates or consume data from the cache) knows about the changes. This concept allows your solution to scale-out without changing the application server JVMs. You can growth your application only in the data grid layer. To start the configuration, you need to configure an machine that points to the server in which you want to execute the Coherence JVMs. WebLogic Server allows you to do this very easily using the Administration Console. In this example, I will call the machine as "coherence-server". Remember that in order to the machine concept works, you need to ensure that the NodeManager are being executed in the target server that the machine points to. The NodeManager executable can be found in <WLS_HOME>/server/bin/startNodeManager.sh. The next thing to do is to configure a Coherence cluster. In the WebLogic administration console, go to Environment > Coherence Clusters and click in "New". Call this Coherence cluster of "my-coherence-cluster". Click in next. Specify a valid cluster address and port. The Coherence members will communicate with each other through this address and port. Our Coherence cluster are now configured. Now it is time to configure the Coherence members and add them to this cluster. In the WebLogic administration console, go to Environment > Coherence Servers and click in "New". In the field "Name" set to "coh-server-1". In the field "Machine", associate this Coherence server to the machine "coherence-server". In the field "Cluster", associate this Coherence server to the cluster named "my-coherence-cluster". Click in "Finish". Start the Coherence server using the "Control" tab of WebLogic administration console. This will instruct WebLogic to start a new JVM of Coherence in the target machine that should join the pre-defined Coherence cluster. Configuring your Java EE Application to Access Coherence Now lets pass to the funny part of the configuration. The first thing to do is to inform your Java EE application which Coherence cluster to join. Oracle had updated WebLogic server deployment descriptors so you will not have to change your code or the containers deployment descriptors like application.xml, ejb-jar.xml or web.xml. In this example, I will show you how to enable DI ("Dependency Injection") to a Coherence cache from a Servlet 3.0 component. In the WEB-INF/weblogic.xml deployment descriptor, put the following metadata information: <?xml version="1.0" encoding="UTF-8"?> <wls:weblogic-web-app xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-web-app" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd http://xmlns.oracle.com/weblogic/weblogic-web-app http://xmlns.oracle.com/weblogic/weblogic-web-app/1.4/weblogic-web-app.xsd"> <wls:context-root>myWebApp</wls:context-root> <wls:coherence-cluster-ref> <wls:coherence-cluster-name>my-coherence-cluster</wls:coherence-cluster-name> </wls:coherence-cluster-ref> </wls:weblogic-web-app> As you can see, using the "coherence-cluster-name" tag, we are informing our Java EE application that it should join the "my-coherence-cluster" when it loads in the web container. Without this information, the application will not be able to access the predefined Coherence cluster. It will form its own Coherence cluster without any members. So never forget to put this information. Now put the coherence.jar and active-cache-1.0.jar dependencies at your WEB-INF/lib application classpath. You need to deploy this dependencies so ActiveCache can automatically take care of the Coherence cluster join phase. This dependencies can be found in the following locations: - <WLS_HOME>/common/deployable-libraries/active-cache-1.0.jar - <COHERENCE_HOME>/lib/coherence.jar Finally, you need to write down the access code to the Coherence cache at your Servlet. In the following example, we have a Servlet 3.0 component that access a Coherence cache named "transactions" and prints into the browser output the content (the ammount property) of one specific transaction. package com.oracle.coherence.demo.activecache; import java.io.IOException; import javax.annotation.Resource; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import com.tangosol.net.NamedCache; @WebServlet("/demo/specificTransaction") public class TransactionServletExample extends HttpServlet { @Resource(mappedName = "transactions") NamedCache transactions; protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { int transId = Integer.parseInt(request.getParameter("transId")); Transaction transaction = (Transaction) transactions.get(transId); response.getWriter().println("<center>" + transaction.getAmmount() + "</center>"); } } Thats it! No more configuration is necessary and you have all set to start producing and getting data to/from Coherence. As you can see in the example code, the Coherence cache are treated as a normal dependency in the Java EE container. The magic happens behind the scenes when the ActiveCache allows your application to join the defined Coherence cluster. The most interesting thing about this approach is, no matter which type of Coherence cache your are using (Distributed, Partitioned, Replicated, WAN-Remote) for the client application, it is just a simple attribute member of com.tangosol.net.NamedCache type. And its all managed by the Java EE container as an dependency. This means that if you inject the same dependency (the Coherence cache named "transactions") in another Java EE component (JSF managed-bean, Stateless EJB) the cache will be the same. Cool isn't it? Thanks to the CDI technology, we can extend the same support for non-Java EE standards components like simple POJOs. This means that you are not forced to only use Servlets, EJBs or JSF in order to inject Coherence caches. You can do the same approach for regular POJOs created for you and managed by lightweight containers like Spring or Seam.

• What's the difference between View Criteria and Where clause?

  - by frank.nimphius

  Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman","serif";} A View Criteria is a filter that you apply programmatically or by definition to a View Object instance. It augments the WHERE clause in a View Object query. Named View Criteria are defined in the Query panel of the View Object and are used ·         In combination with the af:query component to build search forms. To do this, you drag and drop the View Criteria from the Named View Criteria node of the View Object in the Data Controls Panel. In the context menu, you then select the Query component - optionally with a result table ·         To restrict a View Object instance in the Application Module model. For this, select a View object instance in the right hand list of the ADF Business Component Data Model panel. Use the Edit button to add a View Criteria to the View Object instance. This ensures that the View Object instance also runs with a query filter applied. View Criteria use bind variables for query conditions that you want to pass in dynamically at runtime. Beside of the ability to apply View Criteria declaratively, you can apply them programmatically in Java. A WHERE clause, if added to a View Object query by design restricts all instances of this View Object, which usually is not what developers want. Because of the benefits - and the configuration options not explained above but in the product documentation referenced below - the recommendation is to use View Criteria. The product documentation explains View Criteria in chapter 5 of the Developer Guide: http://download.oracle.com/docs/cd/E15523_01/web.1111/b31974/bcquerying.htm#BCGIFHHF
