  • PowerShell - grabbing values out of the registry and running them

    - by Rob Farley
    So I closed an application that runs when Windows starts up, but it doesn’t have a Start Menu entry, and I was trying to find it. Ok, I could’ve run regedit.exe, navigated through the tree and found the list of things that run when Windows starts up, but I thought I’d use PowerShell instead. PowerShell presents the registry as if it’s a volume on a disk, and you can navigate around it using commands like cd and dir. It wasn’t hard to find the folder I knew I was after – tab completion (starting the word and then hitting the Tab key) was a friend here. But unfortunately dir doesn’t list values, only subkeys (which look like folders). PS C:\Windows\system32> dir HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Run PS C:\Windows\system32> Instead, I needed to use Get-Item to fetch the ‘Run’ key, and use its Property property. This listed the values in there for me, as an array of strings (I could work this out using Get-Member). PS C:\Windows\system32> (Get-Item HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Run).Property QuickSet SynTPEnh Zune Launcher PS C:\Windows\system32> Ok, so the thing I wanted wasn’t in there (an app called PureText, whicih lets me Paste As Text using Windows+V). That’s ok – a simple change to use HKCU instead of HKLM (Current User instead of Local Machine), and I found it. Now to fetch the details of the application itself, using the RegistryKey method GetValue PS C:\Windows\system32> (Get-Item HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Run).GetValue('PureText') "C:\Users\Rob\Utilities\PureText.exe" PS C:\Windows\system32> And finally, surrounding it in a bit of code to execute that command. That needs an ampersand and the Invoke-Expression cmdlet. PS C:\Windows\system32> '& ' + (Get-Item HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Run).GetValue('PureText') | Invoke-Expression A simple bit of exploring PowerShell which will makes for a much easier way of finding and running those apps which start with Windows.

  • Strange rendering in XNA/Monogame

    - by Gerhman
    I am trying to render G-Code generated for a 3d-printer as the printed product by reading the file as line segments and the drawing cylinders with the diameter of the filament around the segment. I think I have managed to do this part right because the vertex I am sending to the graphics device appear to have been processed correctly. My problem I think lies somewhere in the rendering. What basically happens is that when I start rotating my model in the X or Y axis then it renders perfectly for half of the rotation but then for the other half it has this weird effect where you start seeing through the outer filament into some of the shapes inside. This effect is the strongest with X rotations though. Here is a picture of the part of the rotation that looks correct: And here is one that looks horrible: I am still quite new to XNA and/Monogame and 3d programming as a whole. I have no idea what could possibly be causing this and even less of an idea of what this type of behavior is called. I am guessing this has something to do with rendering so have added the code for that part: protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.Black); basicEffect.World = world; basicEffect.View = view; basicEffect.Projection = projection; basicEffect.VertexColorEnabled = true; basicEffect.EnableDefaultLighting(); GraphicsDevice.SetVertexBuffer(vertexBuffer); RasterizerState rasterizerState = new RasterizerState(); rasterizerState.CullMode = CullMode.CullClockwiseFace; rasterizerState.ScissorTestEnable = true; GraphicsDevice.RasterizerState = rasterizerState; foreach (EffectPass pass in basicEffect.CurrentTechnique.Passes) { pass.Apply(); GraphicsDevice.DrawPrimitives(PrimitiveType.TriangleList, 0, vertexBuffer.VertexCount); } base.Draw(gameTime); } I don't know if it could be because I am shading something that does not really have a texture. I am using this custom vertex declaration I found on some tutorial that allows me to store a vertex with a position, color and normal: public struct VertexPositionColorNormal { public Vector3 Position; public Color Color; public Vector3 Normal; public readonly static VertexDeclaration VertexDeclaration = new VertexDeclaration ( new VertexElement(0, VertexElementFormat.Vector3, VertexElementUsage.Position, 0), new VertexElement(sizeof(float) * 3, VertexElementFormat.Color, VertexElementUsage.Color, 0), new VertexElement(sizeof(float) * 3 + 4, VertexElementFormat.Vector3, VertexElementUsage.Normal, 0) ); } If any of you have ever seen this type of thing please help. Also, if you think that the problem might lay somewhere else in my code then please just request what part you would like to see in the comments section.

  • How can I transfer photo's from my Kodak camera that normally would use KODAK EASYSHARE Software?

    - by Ryan
    Normally I would plug my camera into my Windows XP pc, and the software would auto start, and transfer the files to a set location. I need to be able to perform the same or similar function on my PC installed with Ubuntu 10.04 (LTS). I would like to plug the camera in (USB), and then be able to select the files I want. At the moment, the camera does not seem to recognise the PC. I do not want to rely on the Windows PC anymore.

  • Gradle for NetBeans RCP

    - by Geertjan
    Start with the NetBeans Paint Application and do the following to build it via Gradle (i.e., no Gradle/NetBeans plugin is needed for the following steps), assuming you've set up Gradle. Do everything below in the Files or Favorites window, not in the Projects window. In the application directory "Paint Application". Create a file named "settings.gradle", with this content: include 'ColorChooser', 'Paint' Create another file in the same location, named "build.gradle", with this content: subprojects { apply plugin: "announce" apply plugin: "java" sourceSets { main { java { srcDir 'src' } resources { srcDir 'src' } } } } In the module directory "Paint". Create a file named "build.gradle", with this content: dependencies { compile fileTree("$rootDir/build/public-package-jars").matching { include '**/*.jar' } } task show << { configurations.compile.each { dep -> println "$dep ${dep.isFile()}" } } Note: The above is a temporary solution, as you can see, the expectation is that the JARs are in the 'build/public-packages-jars' folder, which assumes an Ant build has been done prior to the Gradle build. Now run 'gradle classes' in the "Paint Application" folder and everything will compile correctly. So, this is how the Paint Application now looks: Preferable to the second 'build.gradle' would be this, which uses the JARs found in the NetBeans Platform... netbeansHome = '/home/geertjan/netbeans-dev-201111110600' dependencies { compile files("$rootDir/ColorChooser/release/modules/ext/ColorChooser.jar") def projectXml = new XmlParser().parse("nbproject/project.xml") projectXml.configuration.data."module-dependencies".dependency."code-name-base".each { if (it.text().equals('org.openide.filesystems')) { def dep = "$netbeansHome/platform/core/"+it.text().replace('.','-')+'.jar' compile files(dep) } else if (it.text().equals('org.openide.util.lookup') || it.text().equals('org.openide.util')) { def dep = "$netbeansHome/platform/lib/"+it.text().replace('.','-')+'.jar' compile files(dep) } else { def dep = "$netbeansHome/platform/modules/"+it.text().replace('.','-')+'.jar' compile files(dep) } } } task show << { configurations.compile.each { dep -> println "$dep ${dep.isFile()}" } } However, when you run 'gradle classes' with the above, you get an error like this: geertjan@geertjan:~/NetBeansProjects/PaintApp1/Paint$ gradle classes :Paint:compileJava [ant:javac] Note: Attempting to workaround javac bug #6512707 [ant:javac] [ant:javac] [ant:javac] An annotation processor threw an uncaught exception. [ant:javac] Consult the following stack trace for details. [ant:javac] java.lang.NullPointerException [ant:javac] at com.sun.tools.javac.util.DefaultFileManager.getFileForOutput(DefaultFileManager.java:1058) No idea why the above happens, still trying to figure it out. Once the above works, we can start figuring out how to use the NetBeans Maven repo instead and then the user of the plugin will be able to select whether to use local JARs or JARs from the NetBeans Maven repo. Many thanks to Hans Dockter who put the above together with me today, via Skype!

  • Brasero Burns Data, Not Time - or Piles of Discs

    <b>Linux Insider:</b> "There are a lot of CD/DVD burners for Linux out there, but Brasero stands out as a straightforward, easy-to-use, burner that has some nice extra features but won't make you relearn a lot of complex commands if you only use it occasionally. One nicety is the option to start a burn project and finish it much later, even if you're not using a rewritable disc."

    Reputation management is often seen as necessary only when a negative publicity attack is under way. While working with an accomplished reputation management company in such circumstances can counter an attack and minimize potential damage, the best results are actually seen when companies start working with a company that will both build and protect their reputation prior to any kind of attack.

  • Code Analysis Rule Sets in Visual Studio 2010

    - by Anthony Trudeau
    Microsoft Visual Studio 2010 introduces the concept of rule sets when configuring code analysis.  This is a valuable change from Visual Studio 2008 that I didn't even realize I wanted.  Visual Studio 2008 by default selected all rules and then you had to remove rules on an item by item basis. The rule sets fall into logical groups including "Microsoft All Rules", "Microsoft Basic Correctness Rules", "Microsoft Security Rules", et al.  And within the project properties you can select one rule set, multiple rule sets, or you can define your own rule set based upon another. Selecting a single rule set is obviously the easiest option.  The default rule set when you create a new project is the "Microsoft Minimum Recommended Rules".  However, in my opinion the recommended rules are just too permissive.  For that reason you might want to change your rule set to "Microsoft All Rules" until you get around to creating your own rule set; or alternately you can select multiple rule sets which is an option from the rule set combo box.  The Visual Studio documentation has comprehensive help on what is contained within the rule sets. Creating your own rule set is easy if not obvious.  You need to start a rule set from an existing rule set.  To get started select a rule set in the combo box within the Code Analysis tab of the project properties.  I selected the "Microsoft All Rules" for my rule set, but you may find it easier to start with the "Microsoft Minimum Recommended Rules" if your rules are on the more permissive side. Once your rule set is selected click the Open button.  This will display a dialog that is similar in composition to the rules selection from Visual Studio 2008.  Browsing through the tree view you can select or deselect individual rules within their categories; and you can indicate that the rules are flagged as errors instead of the default which is a warning.  A nice touch to the form is that you get a help pane when you select an individual rule.  That helped me considerably when I first configured my rule set. Once you have finished selecting your rules click the Save tool button, specify a location and name, and click the Save button on the Save As dialog.  Once you're back on the Code Analysis tab you'll choose the Browse option within the combo box and open the file you just created.

  • Backup Azure Tables with the Enzo Backup API

    - by Herve Roggero
    In case you missed it, you can now backup (and restore) Azure Tables and SQL Databases using an API directly. The features available through the API can be found here: http://www.bluesyntax.net/backup20api.aspx and the online help for the API is here: http://www.bluesyntax.net/EnzoCloudBackup20/APIIntro.aspx. Backing up Azure Tables can’t be any easier than with the Enzo Backup API. Here is a sample code that does the trick: // Create the backup helper class. The constructor automatically sets the SourceStorageAccount property StorageBackupHelper backup = new StorageBackupHelper("storageaccountname", "storageaccountkey", "sourceStorageaccountname", "sourceStorageaccountkey", true, "apilicensekey"); // Now set some properties… backup.UseCloudAgent = false;                                       // backup locally backup.DeviceURI = @"c:\TMP\azuretablebackup.bkp";    // to this file backup.Override = true; backup.Location = DeviceLocation.LocalFile; // Set optional performance options backup.PKTableStrategy.Mode = BSC.Backup.API.TableStrategyMode.GUID; // Set GUID strategy by default backup.MaxRESTPerSec = 200; // Attempt to stay below 200 REST calls per second // Start the backup now… string taskId = backup.Backup(); // Use the Environment class to get the final status of the operation EnvironmentHelper env = new EnvironmentHelper("storageaccountname", "storageaccountkey", "apilicensekey"); string status = env.GetOperationStatus(taskId);   As you can see above, the code is straightforward. You provide connection settings in the constructor, set a few options indicating where the backup device will be located, set optional performance parameters and start the backup. The performance options are designed to help you backup your Azure Tables quickly, while attempting to keep under a specific threshold to prevent Storage Account throttling. For example, the MaxRESTPerSec property will attempt to keep the overall backup operation under 200 rest calls per second. Another performance option if the Backup Strategy for Azure Tables. By default, all tables are simply scanned. While this works best for smaller Azure Tables, larger tables can use the GUID strategy, which will issue requests against an Azure Table in parallel assuming the PartitionKey stores GUID values. It doesn’t mean that your PartitionKey must have GUIDs however for this strategy to work; but the backup algorithm is tuned for this condition. Other options are available as well, such as filtering which columns, entities or tables are being backed up. Check out more on the Blue Syntax website at http://www.bluesyntax.net.

  • Commerce Anywhere...Where the Web, Store, Mobile, Social and Call Center Come Together

    - by divya.malik
    I am pleased to introduce guest blogger, Bill Zujewski today. Bill has just joined the Oracle CRM Product Marketing team as part of our recent ATG acquisition. Based in Cambridge, MA Bill was the VP of Product Marketing for ATG and collaborated on eCommerce strategy with some of the best brands in the world. Welcome Bill!! BY BILL ZUJEWSKI "Times are a changing"...or so the song goes. Not long ago, eCommerce just meant having a cool brand and a slick website. Today, customers expect much more... what I think they really want...Commerce Anywhere...a seamless, consistent and personal way to interact or transact business with you and your products, whether they start on the web, go into a store, talk over the phone, access products via their mobile device or on their favorite social media site. They want one more thing... for you to remember them and their history with you... so they can be treated more intelligently and not have to repeat previous interactions. It makes sense to me, I want it too... it saves me time and money. I work with many companies that are trying to understand how to evolve their business structure and technology solutions to meet the challenges of Commerce Anywhere. My advice ... think differently and take a more holistic approach to the customer experience and the cross-channel selling solution. Stop integrating siloed legacy systems and start thinking about a single platform as your new foundation... the e-Commerce platform. I recently wrote a new white paper, Commerce Anywhere - A Business and Technology ! Strategy to Maximize Cross- channel Commerce Growth to help our customers better understand how to create that "Commerce Anywhere" customer experience that customers really want. The paper offers practical insights into an IT transformation that can help you leverage a commerce platform to go beyond the web store front and instead use it to enable rapid expansion into mobile apps, new in-store apps, and interact with your customers through social commerce. Let me know what you think by posting a comment on this blog.

  • New Oracles VM RAC template with support for oracle vm 3 built-in

    - by wcoekaer
    The RAC team did it again (thanks Saar!) - another awesome set of Oracle VM templates published and uploaded to My Oracle Support. You can find the main page here. What's special about the latest version of DeployCluster is that it integrates tightly with Oracle VM 3 manager. It basically is an Oracle VM frontend that helps start VMs, pass arguments down automatically and there is absolutely no need to log into the Oracle VM servers or the guests. Once it completes, you have an entire Oracle RAC database setup ready to go. Here's a short summary of the steps : Set up an Oracle VM 3 server pool Download the Oracle VM RAC template from oracle.com Import the template into Oracle VM using Oracle VM Manager repository - import Create a public and private network in Oracle VM Manager in the network tab Configure the template with the right public and private virtual networks Create a set of shared disks (physical or virtual) to assign to the VMs you want to create (for ASM/at least 5) Clone a set of VMs from the template (as many RAC nodes as you plan to configure) With Oracle VM 3.1 you can clone with a number so one clone command for, say 8 VMs is easy. Assign the shared devices/disks to the cloned VMs Create a netconfig.ini file on your manager node or a client where you plan to run DeployCluster This little text file just contains the IP addresses, hostnames etc for your cluster.

  • Configure Calendar Server 7 to Use the davUniqueId Attribute

    - by dabrain
    Starting with Calendar Server 7 Update 3 (Patch 08) we introduce a new attribute davUniqueId in the davEntity objectclass, to use as the unique identifier.  The reason behind this is quite simple, the LDAP operational attribute nsUniqueId  has been chosen as the default value used for the unique identifier. It was discovered that this choice has a potential serious downside. The problem with using nsUniqueId is that if the LDAP entry for a user, group, or resource is deleted and recreated in LDAP, the new entry would receive a different nsUniqueId value from the Directory Server, causing a disconnect from the existing account in the calendar database. As a result, recreated users cannot access their existing calendars. How To Configure Calendar Server to Use the davUniqueId Attribute? Populate the davUniqueId to the ldap users. You can create a LDIF output file only or (-x option) directly run the ldapmodify from the populate-davuniqueid shell script. # ./populate-davuniqueid -h localhost -p 389 -D "cn=Directory Manager" -w <passwd> -b "o=red" -O -o /tmp/out.ldif The ldapmodify might failed like below, in that case the LDAP entry already have the 'daventity' objectclass, in those cases run populate-davuniqueid script without the -O option. # ldapmodify -x -h localhost -p 389 -D "cn=Directory Manager" -w <passwd> -c -f /tmp/out.ldif modifying entry "uid=mparis,ou=People,o=vmdomain.tld,o=red" ldapmodify: Type or value exists (20) In this case the user 'mparis' already have the objectclass 'daventity', ldapmodify do not take care of this DN and just take the next DN (if you start ldapmodify with -c option otherwise it stop's completely) dn: uid=mparis,ou=People,o=vmdomain.tld,o=red changetype: modify add: objectclass objectclass: daventity - add: davuniqueid davuniqueid: 01a2c501-af0411e1-809de373-18ff5c8d Even run populate-davuniqueid without -O option or changing the outputfile to dn: uid=mparis,ou=People,o=vmdomain.tld,o=red changetype: modify add: davuniqueid davuniqueid: 01a2c501-af0411e1-809de373-18ff5c8d The ldapmodify works fine now. The only issue I see here is you need verify which user might need the 'daventity' objectclass as well. On the other hand start without the objectclass and only add the objectclass for the users where you get 'Objectclass violation' report. That's indicate the objectclass is missing. # ldapmodify -x -h localhost -p 389 -D "cn=Directory Manager" -w <passwd> -c -f /tmp/out.ldif modifying entry "uid=mparis,ou=People,o=vmdomain.tld,o=red" Now it is time to change the configuration to use the davuniquid attribute # ./davadmin config modify -o davcore.uriinfo.permanentuniqueid -v davuniqueid It is also needed to modfiy the search filter to use davuniqueid instead of nsuniqueid # ./davadmin config modify -o davcore.uriinfo.subjectattributes -v "cn davstore icsstatus mail mailalternateaddress davUniqueId  owner preferredlanguageuid objectclass ismemberof uniquemember memberurl mgrprfc822mailmember" Afterward IWC Calendar works fine and my test user able to access all his old events.

  • MapRedux - PowerShell and Big Data

    - by Dittenhafer Solutions
    MapRedux – #PowerShell and #Big Data Have you been hearing about “big data”, “map reduce” and other large scale computing terms over the past couple of years and been curious to dig into more detail? Have you read some of the Apache Hadoop online documentation and unfortunately concluded that it wasn't feasible to setup a “test” hadoop environment on your machine? More recently, I have read about some of Microsoft’s work to enable Hadoop on the Azure cloud. Being a "Microsoft"-leaning technologist, I am more inclinded to be successful with experimentation when on the Windows platform. Of course, it is not that I am "religious" about one set of technologies other another, but rather more experienced. Anyway, within the past couple of weeks I have been thinking about PowerShell a bit more as the 2012 PowerShell Scripting Games approach and it occured to me that PowerShell's support for Windows Remote Management (WinRM), and some other inherent features of PowerShell might lend themselves particularly well to a simple implementation of the MapReduce framework. I fired up my PowerShell ISE and started writing just to see where it would take me. Quite simply, the ScriptBlock feature combined with the ability of Invoke-Command to create remote jobs on networked servers provides much of the plumbing of a distributed computing environment. There are some limiting factors of course. Microsoft provided some default settings which prevent PowerShell from taking over a network without administrative approval first. But even with just one adjustment, a given Windows-based machine can become a node in a MapReduce-style distributed computing environment. Ok, so enough introduction. Let's talk about the code. First, any machine that will participate as a remote "node" will need WinRM enabled for remote access, as shown below. This is not exactly practical for hundreds of intended nodes, but for one (or five) machines in a test environment it does just fine. C:> winrm quickconfig WinRM is not set up to receive requests on this machine. The following changes must be made: Set the WinRM service type to auto start. Start the WinRM service. Make these changes [y/n]? y Alternatively, you could take the approach described in the Remotely enable PSRemoting post from the TechNet forum and use PowerShell to create remote scheduled tasks that will call Enable-PSRemoting on each intended node. Invoke-MapRedux Moving on, now that you have one or more remote "nodes" enabled, you can consider the actual Map and Reduce algorithms. Consider the following snippet: $MyMrResults = Invoke-MapRedux -MapReduceItem $Mr -ComputerName $MyNodes -DataSet $dataset -Verbose Invoke-MapRedux takes an instance of a MapReduceItem which references the Map and Reduce scriptblocks, an array of computer names which are the remote nodes, and the initial data set to be processed. As simple as that, you can start working with concepts of big data and the MapReduce paradigm. Now, how did we get there? I have published the initial version of my PsMapRedux PowerShell Module on GitHub. The PsMapRedux module provides the Invoke-MapRedux function described above. Feel free to browse the underlying code and even contribute to the project! In a later post, I plan to show some of the inner workings of the module, but for now let's move on to how the Map and Reduce functions are defined. Map Both the Map and Reduce functions need to follow a prescribed prototype. The prototype for a Map function in the MapRedux module is as follows. A simple scriptblock that takes one PsObject parameter and returns a hashtable. It is important to note that the PsObject $dataset parameter is a MapRedux custom object that has a "Data" property which offers an array of data to be processed by the Map function. $aMap = { Param ( [PsObject] $dataset ) # Indicate the job is running on the remote node. Write-Host ($env:computername + "::Map"); # The hashtable to return $list = @{}; # ... Perform the mapping work and prepare the $list hashtable result with your custom PSObject... # ... The $dataset has a single 'Data' property which contains an array of data rows # which is a subset of the originally submitted data set. # Return the hashtable (Key, PSObject) Write-Output $list; } Reduce Likewise, with the Reduce function a simple prototype must be followed which takes a $key and a result $dataset from the MapRedux's partitioning function (which joins the Map results by key). Again, the $dataset is a MapRedux custom object that has a "Data" property as described in the Map section. $aReduce = { Param ( [object] $key, [PSObject] $dataset ) Write-Host ($env:computername + "::Reduce - Count: " + $dataset.Data.Count) # The hashtable to return $redux = @{}; # Return Write-Output $redux; } All Together Now When everything is put together in a short example script, you implement your Map and Reduce functions, query for some starting data, build the MapReduxItem via New-MapReduxItem and call Invoke-MapRedux to get the process started: # Import the MapRedux and SQL Server providers Import-Module "MapRedux" Import-Module “sqlps” -DisableNameChecking # Query the database for a dataset Set-Location SQLSERVER:\sql\dbserver1\default\databases\myDb $query = "SELECT MyKey, Date, Value1 FROM BigData ORDER BY MyKey"; Write-Host "Query: $query" $dataset = Invoke-SqlCmd -query $query # Build the Map function $MyMap = { Param ( [PsObject] $dataset ) Write-Host ($env:computername + "::Map"); $list = @{}; foreach($row in $dataset.Data) { # Write-Host ("Key: " + $row.MyKey.ToString()); if($list.ContainsKey($row.MyKey) -eq $true) { $s = $list.Item($row.MyKey); $s.Sum += $row.Value1; $s.Count++; } else { $s = New-Object PSObject; $s | Add-Member -Type NoteProperty -Name MyKey -Value $row.MyKey; $s | Add-Member -type NoteProperty -Name Sum -Value $row.Value1; $list.Add($row.MyKey, $s); } } Write-Output $list; } $MyReduce = { Param ( [object] $key, [PSObject] $dataset ) Write-Host ($env:computername + "::Reduce - Count: " + $dataset.Data.Count) $redux = @{}; $count = 0; foreach($s in $dataset.Data) { $sum += $s.Sum; $count += 1; } # Reduce $redux.Add($s.MyKey, $sum / $count); # Return Write-Output $redux; } # Create the item data $Mr = New-MapReduxItem "My Test MapReduce Job" $MyMap $MyReduce # Array of processing nodes... $MyNodes = ("node1", "node2", "node3", "node4", "localhost") # Run the Map Reduce routine... $MyMrResults = Invoke-MapRedux -MapReduceItem $Mr -ComputerName $MyNodes -DataSet $dataset -Verbose # Show the results Set-Location C:\ $MyMrResults | Out-GridView Conclusion I hope you have seen through this article that PowerShell has a significant infrastructure available for distributed computing. While it does take some code to expose a MapReduce-style framework, much of the work is already done and PowerShell could prove to be the the easiest platform to develop and run big data jobs in your corporate data center, potentially in the Azure cloud, or certainly as an academic excerise at home or school. Follow me on Twitter to stay up to date on the continuing progress of my Powershell MapRedux module, and thanks for reading! Daniel

  • Installed Sun Java 6 - configuration problem when running as sudo

    - by HorusKol
    I have install Sun Java 6 on an Ubuntu server and set an environment variable in the default profile as per the instructions at http://www.edugate.ie/workshop-guides/shibboleth-2-identity-provider-installation-linux-debian-or-ubuntu I then try to run an installer for a Java servlet - but when I run it as myself, it cannot create the required directory in /opt. When I run it as sudo, I am told that JAVA_HOME is not correct and it doesn't even start the installer - shouldn't this be coming from /etc/profile like it is for my normal user?
