• Admin Panel like Custom Framework

  - by bhuvin

  I want to Create a Framework , like Admin panel , which can rule almost all the aspects of what is shown on the frontend. For an (most basic) example: If suppose the links which are to be shown in a navigation area is passed from the server, with the order and the url , etc. The whole aim is to save the time on the tedious tasks. You can just start creating menus and start assigning pages to it. Give a url, actual files which are to be rendered (in case of static files.), in case of dynamic files, giving the file accordingly. And all this is fully server side manageable using different portlets, sort of things. So basic Roadmap is having : Areas like: Header Area - Which can contain logos, links etc. Navigation Area - Which can contains links and submenus. Content Area - Now this is where the tricky part is that that it has zones like: left, center & right. It contains Order in which it has to be displayed. So, when someday we want to change the way the articles appear on the page, we can do so easily, without any deployments. Now these zones can have n number of internal elements, like the word cloud, or the advertisement area. Footer Area: Again similar as Header Area. Currently there is a preexisting custom framework, which uses XSLT files for pulling out data from the server side. And it has the above capabilities. For example: If there's a grid it will be having a <table> tag embedded in the XSLT file. Now whatever might be the source of the data, we serialize this as XML and give it to the XSLT file and the html is derived from this and is appended to the layer in a page. The problem with this approach is: The XSLT conversion is occurring on the server side, so the server is responsible for getting the data, running XSLT transform, and append the html generated to the layer div. So, according to me, firstly this isn't the server's concern to do so. Secondly for larger applications this might be slower. Debugging isn't possible for XSLT transformation. So, whenever we face problems with data its always a bit of a trial & error method. Maintaining it is a bit of an eerie job i.e. styling changes, and other stuff. Adding dynamic values. Like JavaScript can't actually be very easily used in this. Secondly, we can't use JQuery or any other libraries with this since this is all occurring on the server. For now what I have thought about is using Templating - Javascript - JSON combination in place of XSLT, this will be offloaded to the client and the rendering will take place accordingly. This could solve the above problems and also could add mobile support for the same. Only problem which I could think of is that: It is much work and adding new portlets on the go needs to be looked into. What could be the alternatives for this? What kind of problems are there with the JavaScript approach? What are the different ways to implement the same? Are there any existing frameworks for similar usage?

• What's new in Servlet 3.1 ? - Java EE 7 moving forward

  - by arungupta

  Servlet 3.0 was released as part of Java EE 6 and made huge changes focused at ease-of-use. The idea was to leverage the latest language features such as annotations and generics and modernize how Servlets can be written. The web.xml was made as optional as possible. Servet 3.1 (JSR 340), scheduled to be part of Java EE 7, is an incremental release focusing on couple of key features and some clarifications in the specification. The main features of Servlet 3.1 are explained below: Non-blocking I/O - Servlet 3.0 allowed asynchronous request processing but only traditional I/O was permitted. This can restrict scalability of your applications. Non-blocking I/O allow to build scalable applications. TOTD #188 provide more details about how non-blocking I/O can be done using Servlet 3.1. HTTP protocol upgrade mechanism - Section 14.42 in the HTTP 1.1 specification (RFC 2616) defines an upgrade mechanism that allows to transition from HTTP 1.1 to some other, incompatible protocol. The capabilities and nature of the application-layer communication after the protocol change is entirely dependent upon the new protocol chosen. After an upgrade is negotiated between the client and the server, the subsequent requests use the new chosen protocol for message exchanges. A typical example is how WebSocket protocol is upgraded from HTTP as described in Opening Handshake section of RFC 6455. The decision to upgrade is made in Servlet.service method. This is achieved by adding a new method: HttpServletRequest.upgrade and two new interfaces: javax.servlet.http.HttpUpgradeHandler and javax.servlet.http.WebConnection. TyrusHttpUpgradeHandler shows how WebSocket protocol upgrade is done in Tyrus (Reference Implementation for Java API for WebSocket). Security enhancements Applying run-as security roles to #init and #destroy methods Session fixation attack by adding HttpServletRequest.changeSessionId and a new interface HttpSessionIdListener. You can listen for any session id changes using these methods. Default security semantic for non-specified HTTP method in <security-constraint> Clarifying the semantics if a parameter is specified in the URI and payload Miscellaneous ServletResponse.reset clears any data that exists in the buffer as well as the status code, headers. In addition, Servlet 3.1 will also clears the state of calling getServletOutputStream or getWriter. ServletResponse.setCharacterEncoding: Sets the character encoding (MIME charset) of the response being sent to the client, for example, to UTF-8. Relative protocol URL can be specified in HttpServletResponse.sendRedirect. This will allow a URL to be specified without a scheme. That means instead of specifying "http://anotherhost.com/foo/bar.jsp" as a redirect address, "//anotherhost.com/foo/bar.jsp" can be specified. In this case the scheme of the corresponding request will be used. Clarification in HttpServletRequest.getPart and .getParts without multipart configuration. Clarification that ServletContainerInitializer is independent of metadata-complete and is instantiated per web application. A complete replay of What's New in Servlet 3.1: An Overview from JavaOne 2012 can be seen here (click on CON6793_mp4_6793_001 in Media). Each feature will be added to the JSR subject to EG approval. You can share your feedback to [email protected]. Here are some more references for you: Servlet 3.1 Public Review Candidate Downloads Servlet 3.1 PR Candidate Spec Servlet 3.1 PR Candidate Javadocs Servlet Specification Project JSR Expert Group Discussion Archive Java EE 7 Specification Status Several features have already been integrated in GlassFish 4 Promoted Builds. Have you tried any of them ? Here are some other Java EE 7 primers published so far: Concurrency Utilities for Java EE (JSR 236) Collaborative Whiteboard using WebSocket in GlassFish 4 (TOTD #189) Non-blocking I/O using Servlet 3.1 (TOTD #188) What's New in EJB 3.2 ?

• Property overwrite behaviour

  - by jeremyj

  I thought it worth sharing about property overwrite behaviour because i found it confusing at first in the hope of preventing some learning pain for the uninitiated with MSBuild :-)The confusion for me came because of the redundancy of using a Condition statement in a _project_ level property to test that a property has not been previously set. What i mean is that the following two statements are always identical in behaviour, regardless if the property has been supplied on the command line -  <PropertyGroup>    <PropA Condition=" '$(PropA)' == '' ">PropA set at project level</PropA>  </PropertyGroup>has the same behaviour regardless of command line override as -  <PropertyGroup>     <PropA>PropA set at project level</PropA>   </PropertyGroup>  i.e. the two above property declarations have the same result whether the property is overridden on the command line or not.To prove this experiment with the following .proj file -<?xml version="1.0" encoding="utf-8"?><Project ToolsVersion="4.0" >  <PropertyGroup>    <PropA Condition=" '$(PropA)' == '' ">PropA set at project level</PropA>  </PropertyGroup>  <Target Name="Target1">    <Message Text="PropA: $(PropA)"/>  </Target>  <Target Name="Target2">    <PropertyGroup>      <PropA>PropA set in Target2</PropA>    </PropertyGroup>    <Message Text="PropA: $(PropA)"/>  </Target>  <Target Name="Target3">    <PropertyGroup>      <PropA Condition=" '$(PropA)' == '' ">PropA set in Target3</PropA>    </PropertyGroup>    <Message Text="PropA: $(PropA)"/>  </Target>  <Target Name="Target4">    <PropertyGroup>      <PropA Condition=" '$(PropA)' != '' ">PropA set in Target4</PropA>    </PropertyGroup>    <Message Text="PropA: $(PropA)"/>  </Target></Project>Try invoking it using both of the following invocations and observe its output -1)>msbuild blog.proj /t:Target1;Target2;Target3;Target42)>msbuild blog.proj /t:Target1;Target2;Target3;Target4 "/p:PropA=PropA set on command line"Then try those two invocations with the following three variations of specifying PropA at the project level -1)  <PropertyGroup>     <PropA Condition=" '$(PropA)' == '' ">PropA set at project level</PropA>   </PropertyGroup> 2)   <PropertyGroup>     <PropA>PropA set at project level</PropA>   </PropertyGroup>3)  <PropertyGroup>     <PropA Condition=" '$(PropA)' != '' ">PropA set at project level</PropA>   </PropertyGroup>

• Identity in .NET 4.5&ndash;Part 3: (Breaking) changes

  - by Your DisplayName here!

  I recently started porting a private build of Thinktecture.IdentityModel to .NET 4.5 and noticed a number of changes. The good news is that I can delete large parts of my library because many features are now in the box. Along the way I found some other nice additions. ClaimsIdentity now has methods to query the claims collection, e.g. HasClaim(), FindFirst(), FindAll(). ClaimsPrincipal has those methods as well. But they work across all contained identities. Nice! ClaimsPrincipal.Current retrieves the ClaimsPrincipal from Thread.CurrentPrincipal. Combined with the above changes, no casting necessary anymore. SecurityTokenHandler now has read and write methods that work directly with strings. This makes it much easier to deal with non-XML tokens like SWT or JWT. A new session security token handler that uses the ASP.NET machine key to protect the cookie. This makes it easier to get started in web farm scenarios. No need for a custom service host factory or the federation behavior anymore. WCF can be switched into “WIF mode” with the useIdentityConfiguration switch (odd name though). Tooling has become better and the new test STS makes it very easy to get started. On the other hand – and that was kind of expected – to bring claims into the core framework, there are also some breaking changes for WIF code. If you want to migrate (and I would recommend that), most changes to your code are mechanical. The following is a brain dump of the changes I encountered. Assembly Microsoft.IdentityModel is gone. The new functionality is now in mscorlib, System.IdentityModel(.Services) and System.ServiceModel. All the namespaces have changed as well. No IClaimsPrincipal and IClaimsIdentity anymore. Configuration section has been split into <system.identityModel /> and <system.identityModel.services />. WCF configuration story has changed as well. Claim.ClaimType is now Claim.Type. ClaimCollection is now IEnumerable<Claim>. IsSessionMode is now IsReferenceMode. Bootstrap token handling is different now. ClaimsPrincipalHttpModule is gone. This is not really needed anymore, apart from maybe claims transformation (see here). Various factory methods on ClaimsPrincipal are gone (e.g. ClaimsPrincipal.CreateFromIdentity()). SecurityTokenHandler.ValidateToken now returns a ReadOnlyCollection<ClaimsIdentity>. Some lower level helper classes are gone or internal now (e.g. KeyGenerator). The WCF WS-Trust bindings are gone. I think this is a pity. They were *really* useful when doing work with WSTrustChannelFactory. Since WIF is part of the Windows operating system and also supported in future versions of .NET, there is no urgent need to migrate to the 4.5 claims model. But obviously, going forward, at some point you want to make the move.

• Selective Suppression of Log Messages

  - by Duncan Mills

  Those of you who regularly read this blog will probably have noticed that I have a strange predilection for logging related topics, so why break this habit I ask?  Anyway here's an issue which came up recently that I thought was a good one to mention in a brief post.  The scenario really applies to production applications where you are seeing entries in the log files which are harmless, you know why they are there and are happy to ignore them, but at the same time you either can't or don't want to risk changing the deployed code to "fix" it to remove the underlying cause. (I'm not judging here). The good news is that the logging mechanism provides a filtering capability which can be applied to a particular logger to selectively "let a message through" or suppress it. This is the technique outlined below. First Create Your Filter  You create a logging filter by implementing the java.util.logging.Filter interface. This is a very simple interface and basically defines one method isLoggable() which simply has to return a boolean value. A return of false will suppress that particular log message and not pass it onto the handler. The method is passed the log record of type java.util.logging.LogRecord which provides you with access to everything you need to decide if you want to let this log message pass through or not, for example  getLoggerName(), getMessage() and so on. So an example implementation might look like this if we wanted to filter out all the log messages that start with the string "DEBUG" when the logging level is not set to FINEST:  public class MyLoggingFilter implements Filter {     public boolean isLoggable(LogRecord record) {         if ( !record.getLevel().equals(Level.FINEST) && record.getMessage().startsWith("DEBUG")){          return false;            }         return true;     } } Deploying   This code needs to be put into a JAR and added to your WebLogic classpath.  It's too late to load it as part of an application, so instead you need to put the JAR file into the WebLogic classpath using a mechanism such as the PRE_CLASSPATH setting in your domain setDomainEnv script. Then restart WLS of course. Using The final piece if to actually assign the filter.  The simplest way to do this is to add the filter attribute to the logger definition in the logging.xml file. For example, you may choose to define a logger for a specific class that is raising these messages and only apply the filter in that case.  <logger name="some.vendor.adf.ClassICantChange"         filter="oracle.demo.MyLoggingFilter"/> You can also apply the filter using WLST if you want a more script-y solution.

• Disabling the right-click sub menu using JQuery

  - by nikolaosk

  Recently I needed to disable the right-click contextual menu in an HTML page for a very simple HTML application I was creating for a friend.This is going to be a short post where I will demonstrate how to disable the right-click contextual menu.I will use the very popular JQuery Library. Please download the library (minified version) from http://jquery.com/downloadPlease find here all my posts regarding JQuery.In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like.You can use Visual Studio 2012 Express edition. You can download it here. I am going to create a very simple HTML 5 page with some text and an image. The HTML markup for the page follows. <!DOCTYPE html><html lang="en">  <head>    <title>HTML 5, CSS3 and JQuery</title>        <meta http-equiv="Content-Type" content="text/html;charset=utf-8" >    <link rel="stylesheet" type="text/css" href="style.css">     <script type="text/javascript" src="jquery-1.8.2.min.js">        </script><script type="text/javascript"> (function ($) { $(document).bind('contextmenu', function () { return false;}); })(jQuery); </script>       </head>  <body>      <div id="header">      <h1>Learn cutting edge technologies</h1>      <h2>HTML 5, JQuery, CSS3</h2>    </div>      <figure>  <img src="html5.png" alt="HTML 5"></figure>        <div id="main">          <h2>HTML 5</h2>                        <article>          <p>            HTML5 is the latest version of HTML and XHTML. The HTML standard defines a single language that can be written in HTML and XML. It attempts to solve issues found in previous iterations of HTML and addresses the needs of Web Applications, an area previously not adequately covered by HTML.          </p>          </article>      </div>             </body>  </html> This is the JQuery code, I use (function ($) { $(document).bind('contextmenu', function () { return false;}); })(jQuery); I simply disable/cancel the contextmenu event.When I load the simple page on the browser and I right-click the context menu does not appear.Hope it helps!!!

• Xenserver 5.6 SR_BACKEND_FAILURE_47 no such volume group, but it is there

  - by Juan Carlos

  I've looked everywhere (Google, here, a bunch of other sites), and while I have found people with similar problems, I couldn't find a single one with a solution to this. Last night our xenserver 5.6 box corrupted the /var/xapi/state.db, and I couldn't fix the xml, no matter what I did. After a good hour fiddling with the file, I figured it would be faster to just reinstall. The server had one 2tb hard drive running Xen and its VMs, and since Xen's install said it would erase the hard drive it was installed on, I plugged a new harddrive and installed Xen on it, without selecting any hard drives for storage. I Figured I could make it happen after install, using the partition on the old harddrive with all my VMs on it. After instalation finished and the system booted I did: #fdisk -l found the old partition at /dev/sda3 #ll /dev/disk/by-id found the partition at /dev/disk/by-id/scsi-3600188b04c02f100181ab3a48417e490-part3 #xe host-list uuid ( RO) : a019d93e-4d84-4a4b-91e3-23572b5bd8a4 name-label ( RW): xenserver-scribfourteen name-description ( RW): Default install of XenServer #pvscan PV /dev/sda3 VG VG_XenStorage-405a2ece-d10e-d6c5-ede2-e1ad2c29c68d lvm2 [1.81 TB / 204.85 GB free] Total: 1 [1.81 TB] / in use: 1 [1.81 TB] / in no VG: 0 [0 ] #vgscan Reading all physical volumes.

So, now I'm kinda lost about what to do, I'm not used to Xen and most sites I've been finding are really unhelpful. I hope someone can guide me in the right way to fix this. I cant lose those VMs (got backups, but from inside the guests, not the VMs themselves).

• Task Scheduler permissions error for some jobs

  - by MaseBase

  I have recently moved to a 64-bit Windows Server 2008 R2. I setup my Scheduled Tasks to run under one user (TaskUser) specifically created for the scheduler and most run just fine. However some of them do not run under TaskUser but will for my own credentials. Here is the Event Log entry I found, which from my research points me to believe that it doesn't have permissions, but it does. It also has the option "Run with highest privileges" checked on. I have seen this particular checkbox work wonders on some tasks, but I have a number of them that it's not helping for. The error is ERROR_ELEVATION_REQUIRED but the user is a member of the administrators group and has folder/file permission and is set to "Run with highest privileges" Log Name: Microsoft-Windows-UAC/Operational Source: Microsoft-Windows-UAC Date: 4/27/2010 2:21:44 PM Event ID: 1 Task Category: (1) Level: Error Keywords: User: LIVE\TaskUser Computer: www2 Description: The process failed to handle ERROR_ELEVATION_REQUIRED during the creation of a child process.

• IIS 7.5 Error 1007

  - by darkdog

  I have a Windows 2008 R2 Virtual Server. I removed the "Default Web Site" using IIS Manager and now all my other sites now report an error saying they can't access the site (or something similar). I thought I could just remove the role, re-install IIS again and start with a clean slate. After I re-installed IIS it's now reporting the following error in the event log: The World Wide Web Publishing Service (WWW service) failed to register the URL prefix of "http://www.mash-guild.com:80:192.168.245.132/" for the website of "4". The required network connectivity may already be used. The site has been disabled. The data field contains the error number. This is the full version with the german error note (I'm from germany): Der WWW-Publishingdienst (WWW-Dienst) konnte das URL-Präfix "http://www.mash-guild.com:80:192.168.245.132/" für die Website "4" nicht registrieren.

• How to setup Hadoop cluster so that it accepts mapreduce jobs from remote computers?

  - by drasto

  There is a computer I use for Hadoop map/reduce testing. This computer runs 4 Linux virtual machines (using Oracle virtual box). Each of them has Cloudera with Hadoop (distribution c3u4) installed and serves as a node of Hadoop cluster. One of those 4 nodes is master node running namenode and jobtracker, others are slave nodes. Normally I use this cluster from local network for testing. However when I try to access it from another network I cannot send any jobs to it. The computer running Hadoop cluster has public IP and can be reached over internet for another services. For example I am able to get HDFS (namenode) administration site and map/reduce (jobtracker) administration site (on ports 50070 and 50030 respectively) from remote network. Also it is possible to use Hue. Ports 8020 and 8021 are both allowed. What is blocking my map/reduce job submits from reaching the cluster? Is there some setting that I must change first in order to be able to submit map/reduce jobs remotely? Here is my mapred-site.xml file: <configuration> <property> <name>mapred.job.tracker</name> <value>master:8021</value> </property> <!-- Enable Hue plugins --> <property> <name>mapred.jobtracker.plugins</name> <value>org.apache.hadoop.thriftfs.ThriftJobTrackerPlugin</value> <description>Comma-separated list of jobtracker plug-ins to be activated. </description> </property> <property> <name>jobtracker.thrift.address</name> <value>0.0.0.0:9290</value> </property> </configuration> And this is in /etc/hosts file: 192.168.1.15 master 192.168.1.14 slave1 192.168.1.13 slave2 192.168.1.9 slave3

• Windows 7 + Deep Freeze - I'm stuck in an endless reboot loop

  - by myermian

  I have the following setup: Windows 7 Ultimate Deep Freeze I "thawed" my machine last night and performed a Windows Update. The update is having issues (it gets stuck at 32%, fails, and restarts my machine). When it reboots it attempts it again, and again, and again, etc. (Endless loop). I looked online and found some solutions, but none of them seem to be working: When I run Safe Mode, Safe Mode w/ Network, or Safe Mode w/ Command Prompt it attempts to revert the Windows Update changes. However, the problem is with Deep Freeze on (and now in "Frozen" mode) the reverted changes don't stay, and I'm back into the loop of death. Oh, and side note: "Safe Mode w/ Command Prompt" does not actually take me to a command prompt window? Perhaps because it is attempting to complete the Windows Update changes first? I have tried to select the option to NOT restart when an windows error occurs, but it still does. I tried the remainder of all the other options in the F8 screen. The only other option left is to find my Windows 7 Media Disc (I can't find it right now) and use it to repair windows (because for some reason the repair option does not show up in the F8 screen). Is there a way to disable Deep Freeze from loading? When I selected "Safe Mode w/ Command Prompt" I noticed that it loads the DpFrz.sys file. I know that when I'm in the Windows Boot Manager if I press F10 instead of F8 (while highlighting Windows 7) it takes me to an "Edit Boot Options" screen: Edit Windows boot options for: Windows 7 Path: \Windows\system32\winload.exe Partition: 2 Hard Disk: 8e90e329 [ /NOEXECUTE=OPTIN (I CAN EDIT THIS LINE) ] Update: I found my Windows 7 Media Disk and it did not help out. The laptop had the "System Restore" as a partition on the HDD. I later received (in the mail) a Windows 7 Upgrade Disc from Sony to upgrade my system from Windows Vista to Windows 7 Ultimate. I placed the disc into the DVD drive and it does not come up as a "bootable" disc. I'm going to try to find an alternative disc to see if I can get into Command Prompt. Update 2: I got a Windows Repair disc and got into a command prompt window. I got into the registry and disabled Deep Freeze. Also: I renamed the Pending.xml file to Pending.old I cleared out the Windows Temp directory I still am stuck in the loop (though, it isn't an issue with DeepFreeze anymore because I can make changes to the hard drive and they persist). Not sure what to do at this point? Update 3: I ran the repair option and it couldn't repair, but it did point me to something. It says the error was due to a driver that was failing. I have a feeling it is my UPEK Fingerprint scanner.

• Django rewrites URL as IP address in browser - why?

  - by Mitch

  I am using django, nginx and apache. When I access my site with a URL (e.g., http://www.foo.com/) what appears in my browser address is the IP address with admin appended (e.g., http://123.45.67.890/admin/). When I access the site by IP, it is redirected as expected by django's urls.py (e.g., http://123.45.67.890/ - http://123.45.67.890/accounts/login/?next=/) I would like to have the name URL act the same way as the IP. That is, if the URL goes to a new view, the host in the browser address should remain the same and not change to the IP address. Where should I be looking to fix this?

• LaunchDaemon causing Lion to hang on boot

  - by Brett

  I've got a Mac Mini 2011, which I intend to use for a few tasks such as Plex and running a few VM's. I've installed virtualbox, along with XAMPP and phpvirtualbox, which all worked fine. However, getting this to run on startup is proving a real PITA! I'm at the moment trying to get vboxwebsrv running on boot. I've created a launchd plist within /Library/LaunchDaemons to run it and it works fine... well sort of. Lion when booting will show the spinning wheel and stop, never showing a GUI - however if I remote in via screen sharing or SSH, I can login fine and see that vboxwebsrv has launched successfully. Setting this plist to disabled makes lion boot up fine again. Initially I thought it was due to it staying open, so tried to add -b which causes it to run in the background, this just caused launchd to constantly spawn new processes and didn't even fix my problem of Lion being stuck at the spinning wheel. Does anyone have any ideas? I'm losing my mind here! PLIST: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Disabled</key> <false/> <key>KeepAlive</key> <false/> <key>UserName</key> <string>vbox</string> <key>RunAtLoad</key> <true/> <key>OnDemand</key> <false/> <key>Label</key> <string>org.virtualbox.vboxwebsvc</string> <key>ProgramArguments</key> <array> <string>/Applications/VirtualBox.app/Contents/MacOS/vboxwebsrv</string> </array> </dict> </plist>

• IIS can't load Oracle.Web assembly (for ASP.NET membership provider)

  - by Konamiman

  I am trying to configure an IIS web site to use an Oracle database for ASP.NET membership, but I can't get it to work. IIS doesn't seem to be able to load the assembly containing the Oracle membership provider. That's what I have so far: An Oracle 10g database online and with all the tables for ASP.NET membership created. Windows 2008 R2 Standard with the web server role installed, including support for ASP.NET. Oracle 11g Release 2 ODAC 11.2.0.1.2 installed. The installed components are: Oracle data provider for .NET, Oracle providers for ASP.NET, Oracle instant client. The default web site on IIS (I am using that for testing) has the following web.config file: <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.web> <membership defaultProvider="OracleMembershipProvider"> <providers> <remove name="SqlMembershipProvider" /> <add name="OracleMembershipProvider" type="Oracle.Web.Security.OracleMembershipProvider, Oracle.Web, Version=2.112.1.2, Culture=neutral, PublicKeyToken=89b483f429c47342" connectionStringName="OracleServer" /> </providers> </membership> </system.web> </configuration> (Additional attributes on the "add" element omitted for brevity. Also, the connection string is defined for the whole server.) The Oracle.Web.dll file is on the GAC. That's the relevant part of the C:\Windows\Assembly folder: The web site application pool is configured for .NET 2.0, and has 32-bit applications enabled. I have allowed untrusted providers in the IIS' administration.config file (just for the sake of testing, I'll explicitly add the assembly to the trusted providers list later). With all of this setup in place, when I click on the ".NET Users" icon on the IIS manager, I get a warning about the provider having too much privileges, and when I accept I get the following message: There was an error while performing this operation. Details: Could not load file or assembly 'Oracle.Web, Version=2.112.1.2, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The system cannot find the file specified. So, what am I missing? How can I get the Oracle membership provider to work? Thank you! UPDATE: It seems that the problem is not with IIS itself, but with the IIS administrator only. When using the web site configuration tool provided by Visual Studio, everything works fine.

• gunicorn + django + nginx unix://socket failed (11: Resource temporarily unavailable)

  - by user1068118

  Running very high volume traffic on these servers configured with django, gunicorn, supervisor and nginx. But a lot of times I tend to see 502 errors. So I checked the nginx logs to see what error and this is what is recorded: [error] 2388#0: *208027 connect() to unix:/tmp/gunicorn-ourapp.socket failed (11: Resource temporarily unavailable) while connecting to upstream Can anyone help debug what might be causing this to happen?

• Nginx phpmyadmin redirecting to / instead of /phpmyadmin upon login

• SQL Server 2008 R2 upgrade fails on upgrade rule check

  - by Tim

  I'm trying to upgrade an evaluation instance of SQL Server 2008 to a fully licensed instance of SQL Server 2008 R2. I made it most of the way through the installer, but I'm getting stopped at the Upgrade Rules page - the SQL Server Analysis Services Upgrade Service Functional Check is failing. The specific error I get: Rule "SQL Server Analysis Services Upgrade Service Functional Check" failed. The current instance of the SQL Server Analysis Services service cannot be upgraded because the Analysis Services service is disabled or not online. Please start the service and then run the upgrade rules check again. Simple enough - just need to start the service. Here's where it gets troublesome. When I open Services and go to start the SQL Server Analysis Services (MSSQLSERVER) service, it provides me the following message: The SQL Server Analysis Services (MSSQLSERVER) service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs. Trying from the command line as Administrator yields: PS C:\Windows\System32 net start MSSQLServerOLAPService The SQL Server Analysis Services (MSSQLSERVER) service is starting... The SQL Server Analysis Services (MSSQLSERVER) service could not be started. The service did not report an error. More help is available by typing NET HELPMSG 3534. I've tried changing the logon setting of this service to Administrator, a user with admin privileges, and both the Local System and Network Service accounts - nothing works. In addition, when I look at the service through the SQL Server Configuration Manager (also run as Administrator), attempting to change the logon setting for the service results in the message: The server threw an exception. [0x80010105] I have no need for analysis services themselves - all I need is for this one service to be running long enough to do the R2 upgrade, then it can shut down again. Any thoughts on how to get the Analysis Services service running? Update: Checking the event log, I found an error logged to the Application log from the MSSQLServerOLAPService. It has event ID 0, task category (289), and says: The service cannot be started: XML parsing failed at line 1, column 4: Unrecognized input signature.

• Use launchctl to fire an AppleScript script periodically

  - by Daktari

  I have written an AppleScript that lets me back up a particular file. The script runs fine inside AppleScript Editor: it does what it's supposed to do perfectly. So far so good. Now I'd like to run this script at timed intervals. So I use launchctl & .plist to make this happen. That's where the trouble starts. the script is loaded at set interval by launchctl the AppleScript Editor (when open) brings its window (with that script) to the foreground but no code is executed when AppleScript Editor is not running, nothing seems to be happening at all Any ideas as to why this is not working? -- After editing (as per Daniel Beck's suggestions) my plist now looks like: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>KeepAlive</key> <false/> <key>Label</key> <string>com.opera.autosave</string> <key>ProgramArguments</key> <array> <string>osascript</string> <string>/Users/user_name/Library/Scripts/opera_autosave_bak.scpt</string> </array> <key>StartInterval</key> <integer>30</integer> </dict> </plist> and the AppleScript I'm trying to run: on appIsRunning(appName) tell application "System Events" to (name of processes) contains appName end appIsRunning --only run this script when Opera is running if appIsRunning("Opera") then set base_path to "user_name:Library:Preferences:Opera Preferences:sessions:" set autosave_file to "test.txt" set autosave_file_old to "test_old.txt" set autosave_file_older to "test_older.txt" set autosave_file_oldest to "test_oldest.txt" set autosave_path to base_path & autosave_file set autosave_path_old to base_path & autosave_file_old set autosave_path_older to base_path & autosave_file_older set autosave_path_oldest to base_path & autosave_file_oldest set copied_file to "test copy.txt" set copied_path to base_path & copied_file tell application "Finder" duplicate file autosave_path delete file autosave_path_oldest set name of file autosave_path_older to autosave_file_oldest set name of file autosave_path_old to autosave_file_older set name of file copied_path to autosave_file_old end tell end if

  Hey guys, I've been working on this for a day now and still don't know what's wrong. I am essentially building a second environment for our web and app server.

• Windows Server 2008 R2 time keeps changing unexpectedly

  There is a serious problem with one of my servers time. At some random hours (5:59 localtime in the following example) it goes 1 hour back and keeps doing this again and again next times it reaches 5:59. Like this: 5:59-4:59 … 5:59- 4:59 and so on. It stays in the loop until I manually update its time. The server OS is Windows 2008 R2 Standard x64, acting as a standalone web server on the internet. time zone (UTC-05:00). system log: Information 4/13/2012 5:59:34 PM Kernel-General 1 None Information 4/13/2012 5:59:34 PM Kernel-General 1 None Information 4/13/2012 5:59:34 PM Kernel-General 1 None Information 4/13/2012 5:59:34 PM Kernel-General 1 None Information 4/13/2012 5:59:34 PM Kernel-General 1 None Information 4/13/2012 5:59:34 PM Kernel-General 1 None all of the above entries have same content: The system time has changed to ?2012?-?04?-?13T21:59:34.500000000Z from ?2012?-?04?-?13T22:59:34.500000000Z.

• Tomcat with virtual hosts - 404

  - by Thardas

  I have a CentOS 5.2 server set up with Apache 2.2.3 and Tomcat 5.5.27. The server hosts multiple virtual hosts connected to multiple Tomcats. For instance we have one tomcat for development and testing and one tomcat for production. project.demo.us.com points to dev tomcat and project.us.com points to production tomcat. Here's the virtual host's configuration: <VirtualHost *:80> ServerName project.demo.us.com CustomLog logs/project.demo.us.com/access_log combined env=!VLOG ErrorLog logs/project.demo.us.com/error_log DocumentRoot /var/www/vhosts/project.demo.us.com <Directory /var/www/vhosts/project.demo.us.com> Allow from all AllowOverride All Options -Indexes FollowSymLinks </Directory> ########## ########## ########## JkMount /project/* online </VirtualHost> JkMount line defines that we use online worker and our workers.properties contains this: worker.list=..., online, ... worker.online.port=7703 worker.online.host=localhost worker.online.type=ajp13 worker.online.lbfactor=1 And tomcat's conf/server.xml contains: <Connector port="7703" enableLookups="false" redirectPort="8443" protocol="AJP/1.3" URIEncoding="UTF-8" maxThreads="80" minSpareThreads="10" maxSpareThreads="15"/> I'm not sure what redirectPort is but I tried to telnet to that port and there's no one answering, so it shouldn't matter? Tomcat's webapps directory contains project.war and the server automatically deployed it under project directory which contains index.jsp and hello.html. The latter is for static debugging purposes. Now when I try to access http://project.demo.us.com/project/index.jsp, I get Tomcat's HTTP Status 404 - The requested resource () is not available. The same thing happens to hello.html so it's not working with static content either. Apache's access_log contains: 88.112.152.31 - - [10/Aug/2009:12:15:14 +0300] "GET /demo/index.jsp HTTP/1.1" 404 952 "-" "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2" I couldn't find any mention of the request in Tomcat's logs. If I shutdown this specific tomcat, I no longer get Tomcat's 404 but Apache's 503 Service Temporarily Unavailable, so I should be configuring the correct Tomcat. Is there something obvious that I'm missing? Is there any place where I could find out what path the Tomcat is using to look for requested files?
