  • Is this error caused by a 64-bit library being accessed by a Java program running in a 32-bit JVM?

    - by Mike
    I'm trying to create a simple Java app that uses JNI to call some native functions. I've followed the examples in the JNI Programming Guide and can't seem to get them to work. I have the following Hello World program, written in Java: class HelloWorld { private native void print(); public static void main(String [] args) { new HelloWorld().print(); } static { System.load("/home/mike/Desktop/libHelloWorld.so"); } } I compile it using javac HelloWorld.java, just like normal. Then I run javah -jni HelloWorld, and finally the following: gcc34 -shared -fpic -o libHelloWorld.so -I/<path to JDK>/include -I/<path to JDK>/include/linux HelloWorld.c gcc34 is the name of the GCC program on my machine here at work (I don't control that) and I obviously place the real path to the JDK in that command. When I run my program, using the standard java HelloWorld, I get an error saying the following: Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/mike/Desktop/libHelloWorld.so: /home/mike/Desktop/libHelloWorld.so: wrong ELF class: ELFCLASS64 (Possible causes: architecture word width mismatch) at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1778) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1674) at java.lang.Runtime.load0(Runtime.java:770) at java.lang.System.load(System.java:1003) at HelloWorld.<clinit>(HelloWorld.java:8) Could not find the main class: HelloWorld. Program will exit. I know I'm running a 32-bit JVM (and unfortunately, as of right now, I'm not allowed to get a 64-bit JVM). I tried telling GCC to compile in 32-bit mode using the "-m32" option, but we don't have (and again, can't get) what we need for that. Does this sound like a 32/64-bit conflict or something else?

  • Building Web Application project using MSBuild from command line on 64-bit: missing targets file

    - by James Allen
    Building a solution containing a web application project using MSBuild from powershell like this: msbuild "/p:OutDir=$build_dir\" $solution_file Works fine for me on 32-bit, but on a 64-bit machine I am running into this error: error MSB4019: The imported project "C:\Program Files\MSBuild\Microsoft\VisualStudio\v9.0\WebApplications\Microsoft.WebApplication.targets" was not found. Confirm that the path in the declaration is correct, and that the file exists on disk. I am using Visual Studio 2008 and powershell v2. The problem has already been documented here and here. Basically on 64-bit install of VS, the Microsoft.WebApplication.targets needed by MSBuild is in the Program Files(x86) dir, not the Program Files dir, but MSBuild doesn't recognise this and so looks in the wrong place. The two solutions are not ideal: Manually copy the file on 64-bit from Program Files(x86) to Program Files. This is a poor solution - every dev will have to do this manually. Manually edit the csproj file so MSBuild looks in the right place. Again not ideal: I would rather not have to get everyone on 64bit to manually edit csproj files on every new project. e.g. <Import Project="$(MSBuildExtensionsPathx86)\$(WebAppTargetsSuffix)" Condition="Exists('$(MSBuildExtensionsPathx86)\$(WebAppTargetsSuffix)')" /> Ideally I want a way to tell MSBuild to import the target file form the right place from the command line but I can't work out how to do that. Any solutions?

  • IIS will not install on Windows 7 Pro 64 bit

    - by Paul
    I have a new PC running Windows 7 Professional 64 bit. I have an issue installing IIS - it goes through the install process, but at the end tells me "not all components could be installed", with no additional information given. There is no sign of an error in the install log or in event viewer. However, at this point, IIS is installed and working! I can run IIS manager, browse to localhost and see the default page, but at the next reboot the system rolls back and th einstall vanishes. I have tried installing II using the Windows Components section in Add/Remove Programs, I have also tried the Web Platform Installer and using the command line, all with the same end result.

  • allowing 2 VM's to communicate RED HAT 64 bit

    - by ????? ????????
    My physical PC is running 2 VMs on virtualbox. Both of the VM's are linux 64 bit. I am going through this tutorial: http://www.cyberciti.biz/faq/rhel-centos-fedoracore-linux-network-card-configuration/ in order to expose both of their IP's so that they can speak to each other. Mike Schwager November 25, 2009 at 10:55 pm Whoops! In section 3, you forgot about editing /etc/hosts. I believe RedHat comes complete with the system’s host ip address set up in /etc/hosts. Don’t forget to give it a look. I agree with Mike because after I looked into the /etc/hosts files, it has just default localhost stuff in it. How should I reconfigure the hosts file?

  • Registering OCX on 64-bit Windows 7

    - by Jay
    I want to use MSCOMM control in my MS Excel 2010 VBA. The control shall appear in Tools-> Additional Controls dialog box in VBE of MS Excel 2010. I am trying to register MSCOMM32.OCX on my 64-bit Windows 7 machine. However, as I try to register it using regsvr32 as shown in the command window below, I am getting shown error popup. What am I missing here? Why is this component not getting registered? Or this is not the correct way to include MSCOMM control in MS Excel VBA? I have read following: Registering OCX file manually http://social.msdn.microsoft.com/Forums/en/vbgeneral/thread/1f00d6cc-00a9-4ca0-9698-535e2487af31 But to no avail.

  • SQL Server 2008 - Editing Tables: Bit columns require 'True' or 'False'

    - by CJM
    Not so much a question as an observation... I'm just upgrading to SQL Server 2008 on my development machine in anticipation of upgrading my live applications. I didn't anticipate any problems since [I think] I generally use standard T-SQL, and probably not too far from ANSI standard SQL. So far so good, but I was really thrown by a very simple change: I was creating a simple, small look-up table to store a list of codes and including a bit column to indicate the current default code. But when I used the new/modified 'Edit Top 200 Rows' option, and entered my 0s and 1s in the the bit column I got an error: 'Invalid value for cell - String was not recognised as a valid boolean' After a bit of head-scratching, I tried True and False - and they worked. So it seems this new Edit feature requires 4 or 5 characters to be typed, rather than the previous 1. Checking further, we can still use '...where bitval = 1' but can now also use '...where bitval = 'true''. But any results returned render these bit columns as 0 or 1 still. It all sounds like half a step backwards. Not the end of the world, but and unnecessary annoyance. Does anybody have any insight on this issue? Or there any other new Gotchas with SQL Server 2008?

  • Ubuntu Deluge shows errors when downloading large bit torrent files and keeps erroring out after try

    - by MikeN
    Ubuntu Deluge shows errors when downloading large bit torrent files and keeps erroring out after trying to resume. The error on details shows: "Invalid argument". This happens for many large torrents that are running for several days (trying to download.) I try to "resume" and "force rechceck" but it never works. Smaller torrents seem to work ok. What is causing these torrents to never complete? Is there a way to force Deluge to keep auto-resuming every few minutes after a failure instead of just giving up?

  • Slower wireless speed in Ubuntu 12.04 (64-bit) on Asus USB-N13

    - by PhantonTurtle
    I have an Asus USB-N13 which I use for wireless internet on my desktop. The download speed I get on Windows 7 (dual-boot) is 15.22 Mbps. On Ubuntu 12.04 (64-bit) I can only get 1.09 Mbps. I asked a question about this on the Ubuntu forums as well, but I did not get an answer. Here is the output from lsmod | grep rt which gives me, parport_pc 32866 0 rtl8192cu 103297 0 rtl8192c_common 75767 1 rtl8192cu rtlwifi 111202 1 rtl8192cu mac80211 506816 3 rtl8192cu,rtl8192c_common,rtlwifi cfg80211 205544 2 rtlwifi,mac80211 parport 46562 3 parport_pc,ppdev,lp I installed the drivers from Realtek (my chipset is Realtek, not Ralink) but that did not work.

  • Excel Add-In not loading properly with 64-bit Excel 2013

    - by David Hyde
    I have an Excel Add-In saved to an .xla file in %appdata%\Microsoft\Addins. In the subject version of Excel it is checked on the Add-Ins list. One thing this addin does is create a drop-down menu in ThisWorkbook's Workbook_Open sub. But the menu is not created and there is no Add-Ins tab on the ribbon. No error messages. This works fine in Excel 2010 and 2007 (at least), and worked fine on the 32-bit Excel 2013 that came preinstalled on this system before I nuked it. The really maddening thing is that if I get rid of this addin and open that same .xla file, either by double-clicking or using the Open command in Excel, the menu appears as expected. I get the same behavior if I instead open the source .xls file - it all works. I've also tried saving to a .xlam file instead of .xla, but get the same bad result. Any ideas?

  • How to fully use the 4G in my Laptop under Ubuntu 9.10 - 32-bit

    - by jfmessier
    I have a Toshiba A100, which I upgraded to 4G of RAM. The hardware startup indeed shows 4G of RAM, and I recently installed Windows 7, just to see how it behaves on it. So far so good, it displays 4G of RAM. Not that I tried to use it all, but it displays it. Previously under XP, I also would see 4G of RAM. But under Ubuntu 9.10 (32 or 64 bits), it only displays 2.9 G of RAM. And my kernel is the "pae" compiled one, which is supposed to do the trick to work around the 32-bit CPU limitation. How can I get Ubuntu to fully use my 4G of RAM ?

  • Corrupted .WAR file after transfer from 32-64 bit Windows Server to Desktop or vice versa

    - by Albert Widjaja
    Hi All, Does anyone experience this problem of corrupted .WAR file after it has been copied over the network share ? this is .WAR file (Web Archive) the J2EE application file (.WAR file is compressed with the same zip algorithm i think ?) Scenario 1: Windows Server 2008 x64 transfer into Windows XP using RDP client (Local Devices and Resources) Scenario 2: Windows XP 32 bit transfer into Windows Server 2003 x64 using shared network drive (port 445 SMB ?) for both of the scenario it always failed / corrupted (the source code seems to be duplicated at the end of line when you open up in the Eclipse / Java IDE). but when in both scenario i compressed the file into .ZIP file everything is OK. can anyone explains why this problem happens ? Thanks, Albert

  • Windows Media Encoder object not created in ASP.NET on MS Server 2003 64 bit

    - by Ron
    Hello, I created (and used) a Windows Media Encoder object in Microsoft Visual C# 2008 Express Edition on MS Server 2003 64 bit. This worked fine. However, when I attempted to create the equivalent Windows Media Encoder object using Microsoft Visual Web Developer 2008 on MS Server 2003 64 bit, the following exception was thrown: "Retrieving the COM class factory for component with CLSID {632B606A-BBC6-11D2-A329-006097C4E476} failed due to the following error: 80040154." It cannot be that the component isn’t registered, because both have a reference to the same WMEncEng.dll file. The Microsoft Visual Web Developer 2008 code also worked fine on XP 32 bit. Could it be a problem with permissions? Regardless, anyone have any ideas why this problem is occurring and, more importantly, how to resolve it? Thank you. Here are the two code snippets from MS Server 2003 64 bit: Microsoft Visual Web Developer 2008 (did not work): using System; using WMEncoderLib; namespace TestWMEnc { public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { try { WMEncoder encoder = new WMEncoder(); //exception thrown // ... } catch (Exception err) { string exception = err.Message; } } } } Microsoft Visual C# 2008 Express Edition (worked fine): using System; using System.Windows.Forms; using WMEncoderLib; namespace testWMEncoder { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { try { WMEncoder encoder = new WMEncoder(); // ... } catch (Exception err) { string exception = err.Message; } } } }

  • How do app servers inject into private fields?

    - by cibercitizen1
    I saw this question http://stackoverflow.com/questions/2021716/inject-into-private-package-or-public-field-or-provide-a-setter about how to manually inject into annotated private fields (The way is adding setters or through a constructor) But, the point is how do an application server (like glassfish, axis2, jboss, ...) is able to inject into a final private field (without adding setters or constructors to the user class)? Quoting the cited question: public SomeClass { @Inject private SomeResource resource; } Do they use a customized JVM (not the standard one) that allows to access private fields? Thanks

  • java unload static fields

    - by Alina Danila
    I have a java class that uses complex static fields which need special operations as close() so that they are safely cleaned by GC. For the initialization of static fields I use the static block. But I don't now how to unload the static field safely, so that I can call the close() method before the field is cleaned up by GC. Is there any way to unload a static field, similar to the static initialization block?

  • HP Photosmart 7450 Prints Noise On Windows 7 Pro 64-bit

    - by David Mackintosh
    I have received a working (in its last location) HP Photosmart 7450 printer. I connected it up to my Windows 7 Pro 64-bit workstation, and the driver was (apparently) installed. The problem is that whenever I try to print from it -- test page, text from notepad, picture, whatever -- it spins through a half dozen sheets of paper, some of which have fractions of text on them, but most of which are either blank or have line noise printed on them. Noise similar to what was printed out on ye olde laserjet printers when the postscript interpreter failed. HP's web site only has a "use the included driver in Windows 7, be happy" instruction. The driver has been removed and added several times. The printer was previously attached to a XP Home computer and worked correctly without incident. Does anyone have any ideas for troubleshooting before I drop this printer in the river?
